System architects are often impatient about the future, especially when they can see something good coming down the pike. And thus, we can expect a certain amount of healthy and excited frustration when it comes to the Compute Express Link, or CXL, interconnect created by Intel, which with the absorption of Gen-Z technology from Hewlett Packard Enterprise and now OpenCAPI technology from IBM will become the standard for memory fabrics across compute engines for the foreseeable future.
The CXL 2.0 specification, which brings memory pooling across the PCI-Express 5.0 peripheral interconnect, will soon available on CPU engines. Which is great. But all eyes are already turning to the just-released CXL 3.0 specification, which rides atop the PCI-Express 6.0 interconnect coming in 2023 with 2X the bandwidth, and people are already contemplating what another 2X of bandwidth might offer with CXL 4.0 atop PCI-Express 7.0 coming in 2025.
In a way, we expect for CXL to follow the path blazed by IBM’s “Bluelink” OpenCAPI interconnect. Big Blue used the Bluelink interconnect in the “Cumulus” and “Nimbus” Power9 processors to provide NUMA interconnects across multiple processors, to run the NVLink protocol from Nvidia to provide memory coherence across the Power9 CPU and the Nvidia “Volta” V100 GPU accelerators, and to provide more generic memory coherent links to other kinds of accelerators through OpenCAPI ports. But the path that OpenCAPI and CXL will not be exactly the same, obviously. OpenCAPI is kaput and CXL is the standard for memory coherence in the datacenter.
IBM put faster OpenCAPI ports on the “Cirrus” Power10 processors, and they are used to provide those NUMA links as with the Power9 chips as well as a new OpenCAPI Memory Interface that uses the Bluelink SerDes as a memory controller, which runs a bit slower than a DDR4 or DDR5 controller but which takes up a lot less chip real estate and burns less power – and has the virtue of being exactly like the other I/O in the chip. In theory, IBM could have supported the CXL and NVLink protocols running atop its OpenCAPI interconnect on Power10, but there are some sour grapes there with Nvidia that we don’t understand – it seems foolish not to offer memory coherence with Nvidia’s current “Ampere” A100 and impending “Hopper” H100 GPUs. There may be an impedance mismatch between IBM and Nvidia in regards to signaling rates and lane counts between OpenCAPI and NVLink. IBM has PCI-Express 5.0 controllers on its Power10 chips – these are unique controllers and are not the Bluelink SerDes – and therefore could have supported the CXL coherence protocol, but as far as we know, Big Blue has chosen not to do that, either.
Given that we think CXL is the way a lot of GPU accelerators and their memories will link to CPUs in the future, this strategy by IBM seems odd. We are therefore nudging IBM to do a Power10+ processor with support for CXL 2.0 and NVLink 3.0 coherent links as well as with higher core counts and maybe higher clock speeds, perhaps in a year or a year and a half from now. There is no reason IBM cannot get some of the AI and HPC budget given the substantial advantages of its OpenCAPI memory, which is driving 818 GB/sec of memory bandwidth out of a dual chip module with 24 cores. We also expect for future datacenter GPU compute engines from Nvidia will support CXL in some fashion, but exactly how it will sit side-by-side with or merge with NVLink is unclear.
It is also unclear how the Gen-Z intellectual property donated to the CXL Consortium by HPE back in November 2021 and the OpenCAPI intellectual property donated to the organization steering CXL by IBM last week will be used to forge a CXL 4.0 standard, but these two system vendors are offering up what they have to help the CXL effort along. For which they should be commended. That said, we think both Gen-Z and OpenCAPI were way ahead of CXL and could have easily been tapped as in-node and inter-node memory and accelerator fabrics in their own right. HPE had a very elegant set of memory fabric switches and optical transceivers already designed, and IBM is the only CPU provider that offered CPU-GPU coherence across Nvidia GPUs and the ability to hook memory inside the box or across boxes over its OpenCAPI Memory Interface riding atop the Bluelink SerDes. (AMD is offering CPU-GPU coherence across its custom “Trento” Epyc 7003 series processors and its “Aldebaran” Instinct MI250X GPU accelerators in the “Frontier” exascale supercomputer at Oak Ridge National Laboratories.)
We are convinced that the Gen-Z and OpenCAPI technology will help make CXL better, and Boost the kinds and varieties of coherence that are offered. CXL initially offered a kind of asymmetrical coherence, where CPUs can read and write to remote memories in accelerators as if they are local but using the PCI-Express bus instead of a proprietary NUMA interconnect – that is a vast oversimplification – rather than having full cache coherence across the CPUs and accelerators, which has a lot of overhead and which would have an impedance mismatch of its own because PCI-Express was, in days gone by, slower than a NUMA interconnect.
But as we have pointed out before, with PCI-Express doubling its speed every two years or so and latencies holding steady as that bandwidth jumps, we think there is a good chance that CXL will emerge as a kind of universal NUMA interconnect and memory controller, much as IBM has done with OpenCAPI, and Intel has suggested this for both CXL memory and CXL NUMA and Marvell certainly thinks that way about CXL memory as well. And that is why with CXL 3.0, the protocol is offering what is called “enhanced coherency,” which is another way of saying that it is precisely the kind of full coherency between devices that, for example, Nvidia offers across clusters of GPUs on an NVSwitch network or IBM offered between Power9 CPUs and Nvidia Volta GPUs. The kind of full coherency that Intel did not want to do in the beginning. What this means is that devices supporting the CXL.memory sub-protocol can access each other’s memory directly, not asymmetrically, across a CXL switch or a direct point-to-point network.
There is no reason why CXL cannot be the foundation of a memory area network as IBM has created with its “memory inception” implementation of OpenCAPI memory on the Power10 chip, either. As Intel and Marvell have shown in their conceptual presentations, the palette of chippery and interconnects is wide open with a standard like CXL, and improving it across many vectors is important. The industry let Intel win this one, and we will be better off in the long run because of it. Intel has largely let go of CXL and now all kinds of outside innovation can be brought to bear.
Ditto for the Universal Chiplet Interconnect Express being promoted by Intel as a standard for linking chiplets inside of compute engine sockets. Basically, we will live in a world where PCI-Express running UCI-Express connects chiplets inside of a socket, PCI-Express running CXL connects sockets and chips within a node (which is becoming increasingly ephemeral), and PCI-Express switch fabrics spanning a few racks or maybe even a row someday use CXL to link CPUs, accelerators, memory, and flash all together into disaggregated and composable virtual hardware servers.
For now, what is on the immediate horizon is CXL 3.0 running atop the PCI-Express 6.0 transport, and here is how CXL 3.0 is stacking up against the prior CXL 1.0/1.1 release and the current CXL 2.0 release on top of PCI-Express 5.0 transports:
When the CXL protocol is running in I/O mode – what is called CXL.io – it is essentially just the same as the PCI-Express peripheral protocol for I/O devices. The CXL.cache and CXL.memory protocols add caching and memory addressing atop the PCI-Express transport, and run at about half the latency of the PCI-Express protocol. To put some numbers on this, as we did back in September 2021 when talking to Intel, the CXL protocol specification requires that a snoop response on a snoop command when a cache line is missed has to be under 50 nanoseconds, pin to pin, and for memory reads, pin to pin, latency has to be under 80 nanoseconds. By contrast, a local DDR4 memory access one a CPU socket is around 80 nanoseconds, and a NUMA access to far memory in an adjacent CPU socket is around 135 nanoseconds in a typical X86 server.
With the CXL 3.0 protocol running atop the PCI-Express 6.0 transport, the bandwidth is being doubled on all three types of drivers without any increase in latency. That bandwidth increase, to 256 GB/sec across x16 lanes (including both directions) is thanks to the 256 byte flow control unit, or flit, fixed packet size (which is larger than the 64 byte packet used in the PCI-Express 5.0 transport) and the PAM-4 pulsed amplitude modulation encoding that doubles up the bits per signal on the PCI-Express transport. The PCI-Express protocol uses a combination of cyclic redundancy check (CRC) and three-way forward error correction (FEC) algorithms to protect the data being transported across the wire, which is a better method than was employed with prior PCI-Express protocols and hence why PCI-Express 6.0 and therefore CXL 3.0 will have much better performance for memory devices.
The CXL 3.0 protocol does have a low latency CRC algorithm that breaks the 256 B flits into 128 B half flits and does its CRC check and transmissions on these subflits, which can reduce latencies in transmissions by somewhere between 2 nanosecond and 5 nanoseconds.
The neat new thing coming with CXL 3.0 is memory sharing, and this is distinct from the memory pooling that was available with CXL 2.0. Here is what memory pooling looks like:
With memory pooling, you put a glorified PCI-Express switch that speaks CXL between hosts with CPUs and enclosures with accelerators with their own memories or just blocks of raw memory – with or without a fabric manager – and you allocate the accelerators (and their memory) or the memory capacity to the hosts as needed. As the diagram above shows on the right, you can do a point to point interconnect between all hosts and all accelerators or memory devices without a switch, too, if you want to hard code a PCI-Express topology for them to link on.
With CXL 3.0 memory sharing, memory out on a device can be literally shared simultaneously with multiple hosts at the same time. This chart below shows the combination of device shared memory and coherent copies of shared regions enabled by CXL 3.0:
System and cluster designers will be able to mix and match memory pooling and memory sharing techniques with CXL 3.0. CXL 3.0 will allow for multiple layers of switches, too, which was not possible with CXL 2.0, and therefore you can imagine PCI-Express networks with various topologies and layers being able to lash together all kinds of devices and memories into switch fabrics. Spine/leaf networks common among hyperscalers and cloud builders are possible, including devices that just share their cache, devices that just share their memory, and devices that share their cache and memory. (That is Type 1, Type 3, and Type 2 in the CXL device nomenclature.)
The CXL fabric is what will be truly useful and what is enabled in the 3.0 specification. With a fabric, a you get a software-defined, dynamic network of CXL-enabled devices instead of a static network set up with a specific topology linking specific CXL devices. Here is a simple example of a non-tree topology implemented in a fabric that was not possible with CXL 2.0:
And here is the neat bit. The CXL 3.0 fabric can stretch to 4,096 CXL devices. Now, ask yourself this: How many of the big iron NUMA systems and HPC or AI supercomputers in the world have more than 4,096 devices? Not as many as you think. And so, as we have been saying for years now, for a certain class of clustered systems, whether the nodes are loosely or tightly coupled at their memories, a PCI-Express fabric running CXL is just about all they are going to need for networking. Ethernet or InfiniBand will just be used to talk to the outside world. We would expect to see flash devices front-ended by DRAM as a fast cache as the hardware under storage clusters, too. (Optane 3D XPoint persistent memory is no longer an option. But there is always hope for some form of PCM memory or another form of ReRAM. Don’t hold your breath, though.)
As we sit here mulling all of this over, we can’t help thinking about how memory sharing might simplify the programming of HPC and AI applications, especially if there is enough compute in the shared memory to do some collective operations on data as it is processed. There are all kinds of interesting possibilities. . . .
Anyway, making CXL fabrics is going to be interesting, and it will be the heart of many system architectures. The trick will be sharing the memory to drive down the effective cost of DRAM – research by Microsoft Azure showed that on its cloud, memory capacity utilization was only an average of about 40 percent, and half of the VMs running never touched more than half of the memory allocated to their hypervisors from the underlying hardware – to pay for the flexibility that comes through CXL switching and composability for devices with memory and devices as memory.
What we want, and what we have always wanted, was a memory-centric systems architecture that allows all kinds of compute engines to share data in memory as it is being manipulated and to move that data as little as possible. This is the road to higher energy efficiency in systems, at least in theory. Within a few years, we will get to test this all out in practice, and it is legitimately exciting. All we need now is PCI-Express 7.0 two years earlier and we can have some real fun.
The best editor is the person who can take a modest story and make it big, broad, and powerful. Image: Shutterstock
Embody each of your core brand values in their purest form. If you have built a story strategy around uniqueness—the expression of personal gifts, creativity, and nonconformity—you may identify someone who is unwavering in commitment to uniqueness and is extremely articulate about belief in that value.
We can no longer treat our audiences as passive consumers of marketing messages. They must be our partners. And we cannot create those partnerships by simply intruding into their lives and manipulating their actions. Superficially dressing up old tactics in terms of engagement rarely delivers any result from a bored audience.
People who believe and tell the same stories hold the same values. This is what constitutes a worldview. This is what builds a society. In fact, a social norm is just a collection of stories about the who, what, and why of things as they are. Therefore, stories serve as fundamental ingredients in allowing people to create a shared sense of being. Shared stories lead to shared values, which lead to a shared worldview. This calls for attention to the goings on in the world as an Editor would provide it.
Brand stories activate emotions and communicate values. Your brand story is a complete picture of various elements from website copy to social media to traditional ads. It is the way your brand presents itself to the world and the way the public perceives you. Even when you don’t communicate, you actually do.
We need narratives to inspire others to join our cause, for our sales team to convince people to buy, and for our customer support centres to convey a positive experience.
Brand narratives evolve, changing to suit the product, the market, culture, and the audience. A brand’s story must be true, and it must help sell whatever it is you’re selling. You can’t control a brand’s narrative and your audience may take it places you’d never expect it to go, but you can shape it.
The most important rule of brand storytelling and the one most difficult to put into editorial gear is that Your brand is not the hero, the consumer is. To resonate with your audience, content should put the consumer first.
Editors who run brands as fountains of content must set their ambitions to create compelling narratives. When done successfully, a great brand story should create change. If not a huge change, at least an improvement of some kind. Also read: Should brands dissociate with influencers who promote toxic content?
The editor must run the content engine such that it can routinely land an emotional impact or advantage. The story involves the people you are selling to, so drop the spin and tell the truth. The best brand stories are real. But we live in a mutation era where even the internet is going from 2D to 3D, and with the imminent full bloom of the Metaverse, even more people will engage brands beyond reality.
Nearly a hundred million people a day log on to Roblox, Minecraft, and Fortnite Creative, platforms that operate tens of millions of interconnected worlds, which support a consistent virtual identity, virtual goods, and communications suites, and can be accessed from most devices. Most time on these platforms is spent on leisure-playing games and attending concerts—but we are starting to see people go further. No brand or business can neglect its representation given such a massive shift to new media.
Steve Jobs famously said, “it’s better to be a pirate than to join the navy” and that attitude drove a lot of Apple’s most significant product launch campaigns. 1984, an iconic ad, created by TBWA\Chiat\Day and directed by Ridley Scott put Apple on the map at the Super Bowl.
Based on George Orwell’s dystopian novel, the ad cost $650,000 to make and featured a British discus thrower as the woman who stops crowds of men from mindlessly following the words of a dictator on the screen. The ad made a deep statement, on American politics as well as its rivals IBM, in the middle of a very challenging political climate. It proclaimed that ‘Apple was revolutionary.’Also read: Storytelling: Not just a good old practice
But it almost did not air. Test groups found it to be one of the least effective commercials made. Steve Jobs—one of the greats if ever Brand Editors had a hall of Fame—saw to it.
Taking a risk is the hallmark of a great Editor as is a spine of tempered steel.
It was only in 1997 that Think Different was launched, but this advert seeded the spirit much ahead in time.
Not only brands but also the business entity can tell a story—at each stage of its evolution. It has a huge bearing on how it evolves and has value. Ever wondered how a company that has never turned a profit has a multibillion-dollar valuation? Why do some startups attract large investments while others do not? The power of the story very substantially drives corporate value. In business, some storytellers spin compelling narratives essential to success. Tesla, RedBull, Nike, Disney, Apple, and Amazon are all examples of how a company's editorial track can enrich and constrain its narrative.
There are brilliant examples of brand editing everywhere. Some of the most exciting content initiatives are going beyond blogs and articles, to podcasts, video series, and even experiential, real-life encounters. Brand editors take authentic content and find new platforms and avenues on which it can continue to expand ideally in ways that are profitable for their brand.

Cancer of the uterine cervix has become a growing public health challenge with increasing mortality and morbidity among women in lower human development index countries.1 It is reported as the foremost and fourth most common cause of cancer deaths among women.2,3 Bray et al2 reported estimated global new cases of 569,847 (3.2%) and a mortality of 311,365 (3.3%) in 2018. Low- and middle-income countries account for one of the highest prevalence of cervical cancer, with an estimated 90% of global deaths occurring in this region. Cancer of the uterine cervix is the second leading female cancer among Nigerian women, after breast cancer,4 and accounts for more than 10,000 annual deaths.2,5
CONTEXT
Key Objective
What are men and women's knowledge and screening practices of cervical cancer in urban slum community settings?
Knowledge Generated
The mean knowledge score of cervical cancer detection was 5.0 ± 2.6 on a 0- to 39-point scale. Cervical cancer prevention practices (screening and human papillomavirus vaccination) were very low.
Relevance
Low knowledge potentially translates to low practice, as shown in this study. These may result in late detection and presentation at health facilities with poor treatment outcomes. Prevention strategies, at primary and secondary levels, including educational interventions should be encouraged in clinical and other settings to prevent an overburdening of the health system.
The major cause of cervical cancer is the human papillomavirus (HPV), and the disease is sexually transmitted. Other risk factors include high parity, smoking, sexual initiation at an early age, multiple sexual partners, and prolonged use of oral contraceptives. The prevention rate for cervical cancer is high if detected and treated early.6 The WHO recommends regular screening every 3-5 years among women age 30-49 years, in addition to timely treatment of precancerous lesions.2 More recently, the World Health Assembly endorsed the WHO Global Strategy for elimination of cervical cancer. The global targets for 2030 emphasize primary prevention (90% coverage of HPV vaccination of girls by age 15 years) and secondary prevention (70% of women to be screened by age 35 and 45 years).7
Vaccination is reported as an important public health primary prevention approach to reduce the risk of HPV, whereas cervical cytology or Papanicolaou test (Pap smear) is documented as secondary form of prevention.8 In Nigeria, primary prevention through HPV vaccination is not yet part of the national routine immunization program; it is, however, accessible, at a high cost, through a limited number of private and public health care settings. Conventionally, secondary prevention through screening is carried out in Nigeria using Pap smear test.9 However, Pap smear test is not suitable as primary screening in low-resource settings although it has played a substantial role in reducing cervical cancer in developed countries over the past 70 years. Awareness and knowledge of cervical cancer are, however, necessary for improved involvement of women in prevention and screening practices. Several studies have been carried out among Nigerian women to assess the knowledge and screening practices for cervical cancer (including HPV vaccine and Pap smear test) and among HIV-infected women. Most studies have shown an appreciable high knowledge of cervical cancer in urban workplace settings, women attending health facilities, or health workers. Conversely, many studies have documented low knowledge and practice among women,1,10,11 especially at population levels. Incessant creation of awareness about cervical cancer has the potential to increase knowledge and utilization of cervical cancer screening practices.12 More research documenting both men's and women's knowledge of cervical cancer and screening practices among women in urban slum community settings is needed. Focus on men in addition to women on cervical cancer studies is very scanty in Nigeria. Thus, the inclusion of men, and not only women, is important because of the decision-making role of men in Nigerian families and in improving family health. This study therefore investigated the knowledge and screening practices for cervical cancer among male and female adults in urban poor settings in Ibadan, Nigeria. The findings from this study would inform baseline data for planning appropriate health promotion and education, prevention interventions, and policy formulation to prevent and control cervical cancer in poor community settings in Nigeria.
Study Design and Setting
This study used a cross-sectional design in two urban community-based settings in Ibadan, Oyo State, Nigeria. Data collection lasted for 3 weeks in both communities. Ibadan is the largest city in Africa situated in the western region of Nigeria. Ibadan has a population of 3 million and is a combination of both urban and semiurban community settings. Two underserved communities located in the urban slum areas of Ibadan North Local Government Areas (LGAs) were identified. The two communities selected for this study are at the heart of Ibadan city in an urban LGA but have a mixture of higher- and lower-educated people and subsequently a combination of high-, middle-, and low-income communities. The LGA has an estimated population of 308,119, and sanitary conditions in the slum areas are poor as the majority of houses do not have access to potable water and water-flushed toilets.
Study Population, Sampling, and trial Size
All consenting male and female adults in both communities age 18-65 years were eligible to participate in this study. Exclusion criteria included persons who did not provide consent to participate in the study and physically or mentally ill men and women, who were unable to provide adequate information. A previous community-based study by Nnodu et al13 informed the calculation of the trial size of 500, using the Leslie Kish formula. The prevalence of knowledge about HPV was 33%, with calculations on the basis of 95% confidence level, a margin of error of 5%, and a design effect of 1.5. The final trial size calculated was 334, but to cater for attrition and to cover a larger trial area, the trial size was increased to 500. Community members age 18-65 years were randomly selected from the total community population. Simple random sampling technique was used to select participating households, whereas one respondent was selected in each household by ballot to avoid selection bias. A total of 147 males and 353 females completed the electronic data.
Data Collection Methods and Instruments
The research team had earlier visited and interacted with the communities' stakeholders including the heads of the landlord association, executives of the association, and religious leaders. The two communities had committed to support the study and paved the way for easy connection to the community members. In the two communities, 552 people were approached and only 52 declined to participate, mostly because they had to engage with other commitments at the time of the interview. Most of those who consented to participate were self-employed so could create time for the interview.
Data collection instrument was developed and converted into an electronic data capture tool (ODK Collect). Data collection was interviewer administered using the translated instrument into the local language Yoruba and back-translated to English for content validity. Data tool contained both open- and closed-ended questions (Data Supplement). Interviewers were trained before data collection process to ensure increased quality of data set, and all followed a homogenous procedure. Data were pretested in similar community settings before real data collection was undertaken. The ODK tool included questions on sociodemographic characteristics of respondents and cervical cancer questions on awareness and knowledge of cervical cancer risk factors, symptoms, and detection. Questions were also asked about screening practices with Pap smear, visual inspection with acetic acid, reasons for nonscreening, and HPV vaccination. Respondents were asked to identify their responses to knowledge questions with yes or no as appropriate. Open-ended question responses were recorded on the ODK tool by interviewers. Knowledge questions were scored (on a scale of 0-39) for respondents' knowledge of cervical cancer detection, symptoms, and risk factors. Total scores were added together, and a mean knowledge score for respondents was calculated.
Quality Assurance
Throughout the data collection process, research assistants were monitored and gave daily feedback on the research process. The electronic data collected were uploaded daily and checked for completeness and errors. In those cases where there were errors, research assistants were asked to collect additional data and the data previously collected were discarded. Quality assurance meetings were held weekly to review the data collected, weekly targets, and any challenges that research assistants encountered. This enabled immediate response to facilitate ease of data collection procedure.
Data Analysis
Electronic data collected using the ODK tool were checked before they were transferred into the Statistical Package for Social Sciences (IBM SPSS) version 21. Both descriptive and inferential statistics analyses were used to meet the criteria of the study objectives. Categorical variables were presented using frequencies and percentages, whereas continuous variables reported means and standard deviations. Inferential statistics was obtained using chi-square statistics to estimate the degree of association between the variables in the study. Multivariate regression analysis was not carried out because there was no statistical significance from the chi-square statistics.
Ethical Consideration
The study protocol was approved and informed (by signing an informed consent form), and voluntary consents were sought and obtained from community leaders, stakeholders, and all study respondents, before the commencement of data collection (Data Supplement). There were no physical risks to the respondents; data were collected in privacy, and respondents were assured that they would not be penalized in any way if they chose to stop the data collection at any stage. Respondents were assured of confidentiality of responses, and only identification codes were assigned to ODK files. Study findings were disseminated to participating communities after the completion of the study.
The study protocol was approved by the University of Ibadan/University College Hospital Nigeria Ethical Review Committee, Nigeria, with the reference number UI/EC/17/0410.
Socioeconomic Characteristics of Respondents
A majority of respondents were females (70.6%), and the mean age was 35.36 ± 12.24 years. More than half (52.6%) of the respondents had completed secondary school education, with most numerous ethnic group among them being Yoruba (88.8%). A majority (64.0%) of respondents were married, and the most predominant religions were Christianity (51.0%) and Islam (49.0%). A majority of respondents (72.6%) were self-employed with small-scale business. Many (67.2%) had a monthly income of 20,000 naira ($51 US dollars) or less. More than half of the respondents (54.8%) had a household size of two to four people, whereas 37.0% had more than five members (Table 1).
Awareness of Cervical Cancer
A majority of respondents were not aware of cervical cancer screening (91.2%) and Pap smear test (93.6%). Few (10%) had ever heard of HPV vaccine for the prevention of cervical cancer.
Knowledge of Cervical Cancer (detection, symptoms, and risk factors)
The knowledge of the risk factors for cervical cancer showed that majority (92.4%; 0.92 ± 0.27) reported that old age, low socioeconomic status (88%; 0.88 ± 0.33), unhealthy diet (75.8%; 0.76 ± 0.43), and high rate of abortion (73%; 0.73 ± 0.44) were risk factors for cervical cancer (Table 2).
A majority of respondents (91.60%; 0.92 ± 0.28) reported that the absence of menstruation or irregular menstruation, itching at the vagina (91.00%; 0.91 ± 0.29), and painful menstruation (95.40%; 0.95 ± 0.21) constitute symptoms of cervical cancer (Table 2).
The results of knowledge on detection of cervical cancer showed less than half (41.4%; 0.41 ± 0.49) of the respondents reported that cervical cancer can be terminal. However, a majority of respondents (88.6%; 0.89 ± 0.32) reported that it is sufficient to only do cervical cancer test once to eliminate its risk, and 83.4% (0.83 ± 0.37) reported that cervical cancer is a genetic disease, whereas 92.6% (0.93 ± 0.26) reported that postmenopausal women still have the risk of getting cervical cancer.
The mean knowledge score of cervical cancer detection was 5.0 ± 2.6 with a minimum knowledge score of two and a maximum of 13, the mean knowledge score of cervical cancer symptoms was 3.3 ± 0.8 with a minimum knowledge score of one and a maximum of eight, and the mean knowledge score of risk factors for cervical cancer was 6.7 ± 1.6 with a minimum knowledge score of three and a maximum of 13. The overall knowledge of participants was pooled and assessed on a (0-39) point scale. This was further categorized into ranges with 0-18 points as poor knowledge, 19-23 points as fair knowledge, and 24-39 points as good knowledge of cervical cancer. Respondents' overall mean knowledge score was 15.0 ± 4.1. Majority (77.2%) had low knowledge score for cervical cancer.
There was a statistically significant association between knowledge of cervical cancer and employment status of respondents (χ2 = 10.35; P < .05). There was no statistically significant difference between knowledge and sex (Table 3).
Cervical Screening Practices
Only women (n = 353) reported about cervical cancer practices. Very few women had been screened for cervical cancer with the Papanicolaou test (4%), and one woman with visual inspection with acetic acid (0.3%). Four women had taken HPV vaccine before (1.1%) (Table 4).
The overall results of this study indicated low knowledge of cervical cancer and screening practices. The study findings revealed a considerable proportion of the respondents to have had either secondary or tertiary education. Average to high level of education did not seem to translate to awareness or good knowledge of cervical cancer among the study respondents. This was in contrast to findings reported by Ezenwa et al10 among women in similar urban community settings in Nigeria. Importantly, findings highlighted low socioeconomic status on the basis of low income of respondents with majority living on 20,000 naira or less per month (equivalent of 51 dollars per month), and moreover, majority were self-employed with petting trading. This translates to less ability to afford the cost of screening or vaccination for the prevention of cervical cancer, coupled with lack of accessibility. This result was similar to the findings of Olanlesi-Aliu et al14 on the quality of services on cervical cancer being affected by inadequate resources. Subsequently, the employment status was a variable that could exert influence on knowledge of the respondents on cervical cancer.
Poor level of awareness was reported for cervical screening, Pap smear, and HPV vaccine from the results of this study. Previous research findings13,15 corroborated these outcomes. These findings consequently demonstrate a need for increased awareness on cervical cancer, HPV screening, and vaccination, as well as the need for health promotion and education strategies targeting cervical cancer screening and the benefits of vaccination among adults in poor urban community settings in Nigeria. Almost all the knowledge scores for questions on risk factors, symptoms, and detection for cervical cancer had responses below the average. This is suggestive of perceived low susceptibility to the disease, but strikingly, majority perceived postmenopausal women to still have the risk of getting cervical cancer, whereas mean score was high for testing is only needed once to eliminate the risk of cervical cancer. Knowledge gaps among study respondents highlight a crucial need for health education to increase knowledge about cervical cancer. Health education should include recommendations for screening, according to the ACOG. The ACOG highlighted that women age between 25 and 29 years are recommended for cervical cytology or Pap test only at 3-year intervals, whereas those who are 30 years to 65 years could have a combination or cotesting of Pap test and HPV test every 5 years. For women over 65 years, screening can be halted on the basis of acceptable previous negative screening within the past 5 years.16
This study highlights major gaps in prevention practices for cervical cancer and identifies an urgent need to upscale cervical cancer prevention and intervention strategies in urban poor community settings of Nigeria. Findings are similar to a accurate study carried out among women,1 where only two women had gone through cervical cancer screening test, but none of them had taken HPV vaccination. These findings are reflective of the inadequate health programs and services regarding cervical cancer prevention in Nigeria.14
In conclusion, the findings of this study have underscored a necessity for increased awareness creation through health promotion interventions and strategies to alleviate low knowledge of cervical cancer, prevention, and screening practices in poor community settings in Nigeria. The provision of prevention services, which must be accessible and affordable to the populace irrespective of the geographical location, is also needed.

The venerable ATX standard was developed in 1995 by Intel, as an attempt to standardize what had until then been a PC ecosystem formed around the IBM AT PC’s legacy. The preceding AT form factor was not so much a standard as it was the copying of the IBM AT’s approximate mainboard and with it all of its flaws.
With the ATX standard also came the ATX power supply (PSU), the standard for which defines the standard voltage rails and the function of each additional feature, such as soft power on (PS_ON). As with all electrical appliances and gadgets during the 1990s and beyond, the ATX PSUs became the subject of power efficiency regulations, which would also lead to the 80+ certification program in 2004.
Starting in 2019, Intel has been promoting the ATX12VO (12 V only) standard for new systems, but what is this new standard about, and will switching everything to 12 V really be worth any power savings?
As the name implies, the ATX12VO standard is essentially about removing the other voltage rails that currently exist in the ATX PSU standard. The idea is that by providing one single base voltage, any other voltages can be generated as needed using step-down (buck) converters. Since the Pentium 4 era this has already become standard practice for the processor and much of the circuitry on the mainboard anyway.
As the ATX PSU standard moved from the old 1.x revisions into the current 2.x revision range, the -5V rail was removed, and the -12V rail made optional. The ATX power connector with the mainboard was increased from 20 to 24 pins to allow for more 12 V capacity to be added. Along with the Pentium 4’s appetite for power came the new 4-pin mainboard connector, which is commonly called the “P4 connector”, but officially the “+12 V Power 4 Pin Connector” in the v2.53 standard. This adds another two 12 V lines.
In the ATX12VO standard, the -12 V, 5 V, 5 VSB (standby) and 3.3 V rails are deleted. The 24-pin connector is replaced with a 10-pin one that carries three 12 V lines (one more than ATX v2.x) in addition to the new 12 VSB standby voltage rail. The 4-pin 12 V connectors would still remain, and still require one to squeeze one or two of those through impossibly small gaps in the system’s case to get them to the top of the mainboard, near the CPU’s voltage regulator modules (VRMs).
While the PSU itself would be somewhat streamlined, the mainboard would gain these VRM sections for the 5 V and 3.3 V rails, as well as power outputs for SATA, Molex and similar. Essentially the mainboard would take over some of the PSU’s functions.
The folk over at GamersNexus have covered their research and the industry’s thoughts on the course of ATX12VO in an article and video that were published last year. To make a long story short, OEM system builders and systems integrators are subject to pretty strong power efficiency regulations, especially in California. Starting in July of 2021, new Tier 2 regulations will come into force that add more strict requirements for OEM and SI computer equipment: see 1605.3(v)(5) (specifically table V-7) for details.
In order to meet these ever more stringent efficiency requirements, OEMs have been creating their own proprietary 12 V-only solutions, as detailed in GamersNexus’ recent video review on the Dell G5 5000 pre-built desktop system. Intel’s ATX12VO standard therefore would seem to be more targeted at unifying these proprietary standards rather than replacing ATX v2.x PSUs in DIY systems. For the latter group, who build their own systems out of standard ATX, mini-ITX and similar components, these stringent efficiency regulations do not apply.
The primary question thus becomes whether ATX12VO makes sense for DIY system builders. While the ability to (theoretically) increase power efficiency especially at low loads seems beneficial, it’s not impossible to accomplish the same with ATX v2.x PSUs. As stated by an anonymous PSU manufacturer in the GamersNexus article, SIs are likely to end up simply using high-efficiency ATX v2.x PSUs to meet California’s Tier 2 regulations.
Ever since the original ATX PSU standard, the improvements have been gradual and never disruptive. Although some got caught out by the negative voltage rails being left out when trying to power old mainboards that relied on -5 V and -12 V rails being present, in general these changes were minor enough to incorporate these into the natural upgrade cycle of computer systems. Not so with ATX12VO, as it absolutely requires an ATX12VO PSU and mainboard to accomplish the increased efficiency goals.
While the possibility of using an ATX v2.x to ATX12VO adapter exists that passively adapts the 12 V rails to the new 10-pin connector and boosts the 5 VSB line to 12 VSB levels, this actually lowers efficiency instead of increasing it. Essentially, the only way for ATX12VO to make a lot of sense is for the industry to switch over immediately and everyone to upgrade to it as well without reusing non-ATX12VO compatible mainboards and PSUs.
Another crucial point here is that OEMs and SIs are not required to adopt ATX12VO. Much like Intel’s ill-fated BTX alternative to the ATX standard, ATX12VO is a suggested standard that manufacturers and OEMs are free to adopt or ignore at their leisure.
Important here are probably the obvious negatives that ATX12VO introduces:
Add to this potential alternatives like Seasonic’s CONNECT module. This does effectively the same as the ATX12VO standard, removing the 5 V and 3.3 V rails from the PSU and moving them to an external module, off of the mainboard. It can be fitted into the area behind the mainboard in many computer cases, making for very clean cable management. It also allows for increased efficiency.
As PSUs tend to survive at least a few system upgrades, it could be argued that from an environmental perspective, having the minor rails generated on the mainboard is undesirable. Perhaps the least desirable aspect of ATX12VO is that it reduces the modular nature of ATX-style computers, making them more like notebook-style systems. Instead, a more reasonable solution here might be that of a CONNECT-like solution which offers both an ATX 24-pin and ATX12VO-style 10-pin connectivity option.
In the larger scheme of power efficiency it can be beneficial to take a few steps back from details like the innards of a computer system and look at e.g. the mains alternating current (AC) that powers these systems. A well-known property of switching mode power supplies (SMPS) like those used in any modern computer is that they’re more efficient at higher AC input voltages.
This can be seen clearly when looking for example at the rating levels for 80 Plus certification. Between 120 VAC and 230 VAC line voltage, the latter is significantly more efficient. To this one can also add the resistive losses from carrying double the amps over the house wiring for the same power draw at 120 V compared to 230 VAC. This is the reason why data centers in North America generally run on 208 VAC according to this APC white paper.
For crypto miners and similar, wiring up their computer room for 240 VAC (North American hot-neutral-hot) is also a popular topic, as it directly boosts their profits.
Whether ATX12VO will become the next big thing or fizzle out like BTX and so many other proposed standards is hard to tell. One thing which the ATX12VO standard has against it is definitely that it requires a lot of big changes to happen in parallel, and the creation of a lot of electronic waste through forced upgrades within a short timespan. If we consider that many ATX and SFX-style PSUs are offered with 7-10 year warranties compared to the much shorter lifespan of mainboards, this poses a significant obstacle.
Based on the sounds from the industry, it seems highly likely that much will remain ‘business as usual’. There are many efficient ATX v2.x PSUs out there, including 80 Plus Platinum and Titanium rated ones, and Seasonic’s CONNECT and similar solutions would appeal heavily to those who are into neat cable management. For those who buy pre-built systems, the use of ATX12VO is also not relevant, so long as the hardware is compliant to all (efficiency) regulations. The ATX v2.x standard and 80 Plus certification are also changing to set strict 2-10% load efficiency targets, which is the main target with ATX12VO.
What would be the point for you to switch to ATX12VO, and would you pick it over a solution like Seasonic CONNECT if both offered the same efficiency levels?

The framework to implement genomics-driven therapeutic oncology has been rapidly established in leading cancer centers worldwide. An exponential growth in characterized cancer genomes has ensued.1 The results of next-generation sequencing (NGS) assays are intricate and provide a multitude of somatic mutations in hundreds of genes. Mutation rates vary significantly between different cancers.2 Many somatic genetic variants are characterized as variants of unknown significance, and the implication of multiple mutations within a single tumor is poorly defined.3 Moreover, tumors possess intratumoral genetic heterogeneity, adding another layer of complexity to NGS results.4
CONTEXT
Key Objective
Algorithms to interpret the pathogenicity and clinical actionability of next-generation sequencing (NGS)–detected sequence variants have been implemented; however, little is known about their relative performance in clinical practice. The clinical interpretation of genomic alterations remains a major bottleneck for realizing precision medicine. We sought to examine the concordance for pathogenicity and clinical actionability of three annotation services available to the VA Precision Oncology Program (N-of-One, OncoKB, and Watson for Genomics).
Knowledge Generated
We demonstrate that NGS annotation services have wide-ranging agreements in pathogenicity (30%-76%). Moreover, there was moderate agreement (96.9%) in level 1 drug actionability.
Relevance
We anticipate these findings will encourage improvement in the precision of NGS multigene panel annotation. We provide detailed information regarding NGS panels, gene variant pathogenicity, annotation ontology, and level 1 drug actionability by annotation service. This study has significant implications for precision oncology clinical trials and molecular tumor boards.
At many institutions, including the Veterans Affairs (VA) healthcare system, molecular tumor boards (MTBs) have been instituted to interpret the results of NGS and develop treatment recommendations. In some instances the whole genome is sequenced, and in other cases selected subsets of genes are sequenced with smaller panels. Identified alterations that are of particular clinical interest include driver mutations or druggable mutations.1 For use in clinical decision making, identified gene variants must be annotated or interpreted in terms of the likelihood of their tumorigenicity and drug actionability.5 There are many resources to assist with data curation, including OncoKB (Memorial Sloan Kettering Cancer Center, New York, NY),6 My Cancer Genome (Vanderbilt-Ingram Cancer Center, Nashville, TN),7 Precision Medicine Knowledge Base (Weill Cornell Medicine Englander Institute for Precision Medicine, New York, NY),8 Personalized Cancer Therapy (MD Anderson Cancer Center, Houston, TX),9 CIViC (Washington University in St Louis School of Medicine, St Louis, MO),10 Jackson Laboratory Clinical Knowledgebase (Jackson Laboratory, Bar Harbor, ME),11 Cancer Genome Interpreter (Barcelona, Spain),5 Cancer Driver Log (omicX, Le-Petit-Quevilly, France),12 and N-of-One (NoO; Concord, MA).13 The identification of mutations that are pathogenic and actionable is generally performed by multidisciplinary teams who reference genomic databases, published literature, and clinical trials. The development of cognitive computing, such as Watson for Genomics (WfG), has also garnered interest in precision oncology. WfG14 is a cloud-based service that uses computerized models to simulate human thought to analyze large volumes of genome data and generate evidence-based guidelines.
The ultimate objective of gene sequencing is to Boost patient outcomes by matching patients to specific treatments that target mutations driving the growth of individual tumors. The landscape of genetic tests has evolved from single mutation to small hotspot mutation panels, large gene panels, and whole exome and whole genome platforms. The interpretation of the clinical significance of these genomic mutations has become a formidable task because of the number of genes tested and limited understanding of normal genetic variation as well as pathogenic gene-to-gene interaction. Although professional societies have recently published consensus guidelines15 for the use and interpretation of NGS, they have not been extensively used in practice. Moreover, traditional clinical trial design approaches of molecularly unselected tumor types may no longer be appropriate because of the molecular heterogeneity of tumors from each primary site (eg, breast). This has led to the development of basket and umbrella trial designs as well as precision genomic oncology trials at the point of care. An urgency exists to examine the various annotation services and clinical support tools available to ensure quality of NGS in oncology.
The VA National Precision Oncology Program (NPOP)16 initially used two commercial vendors for NGS testing, Personal Genome Diagnostics (PGDx, Baltimore, MD) and Personalis (Menlo Park, CA), that used the NoO commercial annotation service. In addition, WfG was available to the VA through a gift from IBM. Until NPOP accrues substantial outcomes data, treatment recommendations are largely based on biomarker panels, annotations, and relevant patient characteristics.17 NPOP also references open data sources, including OncoKB (an evidence source, not an annotation provider), when interpreting pathogenicity and actionability of gene variants. For some variants and cases, annotation is assisted by a molecular pathologist. The primary objective of this study was to assess the concordance for pathogenicity determination and clinical actionability for the annotation services available to NPOP.
Sequencing data from all patients who underwent NGS testing under NPOP since its genesis in 2015 through 2017 were analyzed. The work described here was conducted to assess the quality of annotation services available to the NPOP, a clinical operational program that is not research and does not require institutional review board review; permission to publish was obtained from the appropriate VA authority. Details of the NPOP have been published previously.16 The goal is to use NGS testing to facilitate patient access to US Food and Drug Administration (FDA)–approved targeted therapies and immune checkpoint inhibitors and increase participation in clinical trials (Data Supplement). Clinical trials have been the recommended option in > 50% of cases for which there was no FDA-approved therapy. NGS results were generated through two contracted vendors: PGDx18 (CancerSELECT 125, PlasmaSELECT 64, CancerSELECT 88, and CancerSELECT 203) and Personalis (ACE Cancer Plus 181)19 (Data Supplement).
We matched gene variants for the two contracted vendors, PGDx and Personalis, to compare vendor recommendations as well as commercial annotation services for the same unique gene variant. NGS-detected variants were annotated by the sequencing vendor using the commercial annotation service NoO. We examined NoO as implemented by the vendors. NPOP staff re-annotated DNA sequence results using WfG and OncoKB. IBM donated use of WfG to the VA; OncoKB is created and maintained by Memorial Sloan Kettering Cancer Center (MSKCC) and available online.6
After completion of sequencing, results were uploaded by an NPOP data scientist to WfG (including tumor type, a list of sequence variants as a variant call file, presence of gene fusions, and gene copy number variation). Results were routinely uploaded into WfG as part of routine test interpretation workflow. Batch analysis was performed approximately weekly using a custom-built informatics workflow and a packaging tool provided by IBM. WfG assigned a pathogenicity label to each variant or fusion. Drug matching for pathogenic variants is also part of the WfG analysis pipeline. Variants that are pathogenic or likely pathogenic are matched with FDA-approved drugs and actively recruiting clinical trials using levels of evidence (level 1, 2A, 2B, 3A, 3B, 4, or R1; Tables 1 and 2).3 For actionability, WfG uses a subset of National Cancer Institute (NCI) thesaurus terms for diagnosis coding.20 WfG was performed on all samples as part of NPOP workflow, and OncoKB analysis was performed on an ad hoc basis in response to NPOP consults and/or MTB cases.
Using the same unique gene variants annotated by NoO and WfG, we queried all variants using the OncoKB curated database for the current study (Data Supplement). The public database21 includes information on the clinical actionability for each somatic gene variant organized by indication and four-tier levels of evidence (Tables 1 and 2) which are ultimately incorporated into cBioPortal22 for Cancer Genomics to aid physicians and cancer researchers.6 Many genes involved in tumorigenesis are not targetable with currently available drugs. More than 90% of alterations in OncoKB have biologic effects and are classified as oncogenic but not actionable. For actionability, tumor ontology is considered. OncoKB contains 43 tumor types with biomarker-drug associations and uses an open-source ontology, OncoTree,23 which was developed at MSKCC (699 tumor types). The Clinical Genomics Annotation Committee (CGAC) reviews the OncoKB alteration across 22 disease management teams. Curation reviews occur every 3 months, and CGAC recommendations and feedback are updated in real time.6
For this study, levels of evidence 2A and 2B were consolidated to level 2 and levels 3A and 3B to level 3 for both WfG and OncoKB. For actionability annotation comparisons, we mapped ontology from WfG to OncoKB to ensure that gene variants were properly annotated with their respective tumor type. In addition, for actionability annotation comparisons, we excluded microsatellite instability (MSI), as the MSI status was not entered into WfG and we do not have MSI information from WfG.
Among 1,227 NGS results, 1,388 unique variants were observed in 117 genes. The entire set of unique gene variants is shown in the Data Supplement. The genes with the largest number of variants included were: TP53 (270), STK11 (92), CDKN2A (81), ATM (67), PTEN (52), NF1 (46), and BRCA2 (45). The most common cancer was lung adenocarcinoma in 35.86% (440). Other cancer types included colon adenocarcinoma 9.21% (113) and lung squamous cell carcinoma 9.05% (111). The complete list of cancer types is shown in Figure 1.
Of the 1,388 unique gene variants, 1,082 were identified only by PGDx (a larger proportion of the samples were sequenced by PGDx), and 480 were identified only by Personalis, whereas 174 gene variants were generated by both vendors in different specimens. NoO classification should be similar for both vendors. The unique gene variants generated by each vendor are shown in the Data Supplement. The genes included in the gene panels are listed in the Data Supplement. We also list the well-characterized genes of each panel as well as the genes for which copy analysis is performed. For panel distribution by NGS samples, see the Data Supplement. All unique gene variants were annotated by NoO, WfG, and OncoKB. Out of the 1,388 unique gene variants, 337 (24.2%) were variants of unknown significance by OncoKB. Out of the 1,388 unique gene variants, 270 (19.4%) were variants of unknown significance by WfG.
For pathogenicity annotation, (ie, pathogenic and likely pathogenic variants v all other variants), there was fair agreement between WfG and OncoKB (76%; kappa, 0.22) and no agreement between WfG and NoO (30%; kappa, −0.26) as well as NoO and OncoKB (42%; kappa, −0.07; Table 3; Fig 2; Appendix Fig A1).

There were 91 unique gene variant–diagnosis combinations identified as having level 1 drug actionability recommendations identified by WfG, OncoKB, or both (not available from NoO). As part of actionability annotation, we mapped diagnosis ontology from WfG to OncoKB for each observed diagnosis (Data Supplement).
There was moderate agreement between WfG and OncoKB (96.9%; kappa, 0.445), with 58 variants identified only by WfG as level 1 and 6 variants identified only by OncoKB as level 1 (Table 4). The complete set of level 1 drug recommendations for WfG and OncoKB are shown in the Data Supplement. When both annotation services had level 1 drug actionability, the recommended drugs were overwhelmingly identical. An example of a unique gene variant with drug actionability concordance is the exon 19 deletion in lung adenocarcinoma, EGFR-L747_S752del, with level 1 evidence for use of erlotinib, afatinib, or gefitinib using both WfG and OncoKB annotation services. Response rates of tumors with EGFR exon 19 deletions at L747 have been reported as high as 83.3%.24

Among the 33 unique gene variant diagnoses identified as level 1 by OncoKB, WfG classification was level 1 in 27; for the 6 cases with discordant classification in WfG, 5 cases were lung adenocarcinoma EGFR mutations and a melanoma BRAF-V600R mutation. For the BRAF-V600R mutation in melanoma, WfG had no level 1 recommendations, whereas OncoKB had 5 drug or drug combinations as level 1. BRAF-V600R mutations constitute approximately 3%-7% of all BRAF mutations and were not included in the original BRAF/MEK inhibitors clinical trials.25 Although V600R is not listed on the BRAF/MEK FDA label, National Comprehensive Cancer Network panel guidelines from as early as 2016 consider single-agent BRAF inhibitor monotherapy and BRAF/MEK inhibitor combination therapy an appropriate treatment of all activating BRAF mutations, including V600R, V600D, and others.26 For EGFR mutations in lung adenocarcinoma (EGFR-A750P, EGFR-E746_T751delinsI, EFGR-G719C, EGFR-L861Q, and EGFR-S7681), WfG had no recommendations in 3 variants and had level 2A for EGFR-G719C and level 3B for both EGFR-A740P and EGFR L861Q for drugs afatinib, erlotinib, and gefitinib. For EGFR-L861Q, an uncommon EGFR mutation, the afatinib FDA label expanded to include EGFR-L861Q in January of 2018, which was after our annotation analysis. These approvals were based on findings from the phase 2 LUX-Lung 2 trial as well as the phase 3 LUX-Lung3 and LUX-Lung 6 trials that showed an objective response rate of 66% (95% CI, 47% to 81%).27
Among the 85 unique gene variant diagnoses identified as level 1 by WfG, OncoKB classification was level 1 in 27, and 58 had discordant classification. Most of the gene variant diagnoses (40/58 [68.9%]) with discordant recommendations were mismatch repair (MMR) genes, such as MLH1, MSH2, MSH6, and PMS2. The remaining gene variant diagnoses (18/58; 31.0%) with discordant recommendations included genes CDK4, EGFR, FGFR1, FLT4, KIT, PDGFRA, PIK3CA, POLE, PTEN, TSC1, TSC2, VEGFA, and VHL. For a lung adenocarcinoma case with MLH1-A42, which is part of DNA MMR genes and known to have increased MSI, WfG provide a level 1 recommendation for atezolizumab, nivolumab, and pembrolizumab. Although MMR status predicts the clinical benefit of immune checkpoint blockade in multiple tumor types,28,29 none of these drugs are FDA approved for MLH1 mutants. Similarly, for other MMR gene variants, WfG provided level 1 recommendations in the absence of an FDA on-label indication.
Precision medicine has promoted the development of biomarker-driven treatment strategies. There has been a surge in the genetic testing market, with a 10% annual increase in new genetic tests and a 20% annual increase in gene-based diagnostic tests.15,30 NGS generates massive amounts of data, and different biologic questions require the development of specific bioinformatics pipelines, which are frequently platform specific.30,31 The processing of raw sequence data has a profound effect on patient care and outcomes, and NGS test validation is necessary.32 Until recently, there were no established uniform technical standards for reporting tumor-derived NGS gene panel sequencing results.33 In this analysis, we examine a large number of clinically observed unique gene variants and compare annotations for pathogenicity and actionability through two commercial services, NoO and WfG, as well as an open database, OncoKB.
In efforts to establish guidelines for NGS gene panel interpretation of somatic variants, the Association of Molecular Pathology (AMP) and College of American Pathologists (CAP) issued a joint consensus of classification (Table 5).32,33 The four-tier system has different nomenclature and classification as compared with WfG and OncoKB (Tables 1 and 2). The WfG and OncoKB levels of evidence are similar and compatible, but not identical, to the AMP/CAP/ASCO evidence levels. The OncoKB evidence levels were mapped to the evidence levels for AMP/CAP/ASCO tier I and II variants (Table 5).34 We used the WfG and OncoKB classification systems to compare their levels to each other, and we found that variants classified as pathogenic had a wide range of concordance, from 30% to 76% (Fig 2; Table 3; Appendix Fig A1). In routine clinical practice, only gene variants that are pathogenic or likely pathogenic are considered for actionability, so misclassification in pathogenicity could readily affect provider prescribing. For drug actionability, there was moderate-strength agreement 96.9% (kappa, 0.445) for levels 1. In practice, levels of evidence 1 and 2A both frequently result in use of a targeted drug, so concordance in level 2A may be similar to level 1, and their combination may Boost concordance among annotation services for actionability. However, we expect greater discordance among levels of evidence 2B to 4.

Although no direct comparisons between NoO, WfG, and OncoKB have been previously performed, WfG has been compared with MTBs.3 The utility of WfG was compared with MTBs by examining 1,018 cases analyzed by the University of North Carolina’s Human-MTB. WfG identified an additional 8 actionable genes (7 of which passed actionability criteria by Human-MTB). Mutations in these 8 genes were identified in 231 and 96 patients out of 703 and 315 patients with already identified actionable and no actionable mutations, respectively.3 Of the 7 actionable genes identified by WfG, 3 had no clinical trial available, and 4 were made potentially eligible for a biomarker-selected clinical trial. The reason for the added genes by WfG was believed to be the opening of several clinical trials within weeks of the WfG analysis. Most genes identified and reclassified as actionable, however, have yet to demonstrate their utility as predictive biomarkers of response to the recommended therapy. These actionable mutations identified by WfG were found retrospectively in 323 patients, of whom only 47 (4.6%) had active disease requiring further therapy. Moreover, none of the patients had treatment altered based on WfG’s recommendation. Cognitive computing may supplement MTBs, and multiple studies have shown concordance of > 90%.35,36 WfG may provide additional decision support in the current era of rapid generation of information from clinical trials.
Currently, existing evidence does not support population-based universal tumor sequencing.37 The SHIVA trial (ClinicalTrials.gov identifier: NCT01771458) examined patients with any metastatic solid tumor refractory to standard treatment and randomly assigned 195 to receive treatment on the basis of molecular profile (n = 99) versus standard treatment (n = 95). Median progression-free survival was 2.3 months (95% CI, 1.7 to 3.8 months) in the experimental group versus 2.0 months (95% CI, 1.8 to 2.1 months) in the control group (hazard ratio, 0.88; 95% CI, 0.65 to 1.19; P = .41). The study used a variety of tumor types and histologies with single molecular alterations as a predictor for efficacy of targeted agents in heavily pretreated patients, possibly reducing their effectiveness. Nevertheless, there were no differences in progression-free survival or overall survival, and off-label use of targeted agents was discouraged.38 The benefit of off-label use of molecularly targeted agents is largely debated in oncology; however, most agree that clinical trial enrollment should be encouraged to identify predictive druggable biomarkers.
Other prospective studies, including EXACT,39 MOSCATO-01 (ClinicalTrials.gov identifier: NCT01566019),40,41 and MD Anderson’s Phase I Clinic42,43 have shown promising results for targeted therapy on previously treated solid tumors. Additional studies examining the efficacy of off-label use of targeted therapy on the basis of NGS test results are underway: ASCO’s Targeted Agent and Profiling Utilization Registry (TAPUR) study (ClinicalTrials.gov identifier: NCT02693535),44 NCI-MATCH (Molecular Analysis for Therapy Choice) trial (ClinicalTrials.gov identifier: NCT02465060),45 and Pediatric MATCH (ClinicalTrials.gov identifier: NCT03155620). Results from NCI-MATCH for patients with PIK3CA mutations treated with taselisib show 0% objective response rate,46 whereas patients with FGFR pathway mutations treated with AZD4547 showed a 5% objective response rate.47 Currently, there are no randomized controlled trial results supporting a universal NGS-based treatment paradigm. Despite this, NGS testing continues to be incorporated into the clinic.48 In a accurate survey of 1,281 US oncologists, 75.6% reported using NGS tests to guide treatment decisions. Of these, 34% used them for patients with advanced refractory disease, and 17.5% used them for decisions on off-label use of FDA-approved drugs.49 More than 50% reported that NGS tests were difficult to interpret either often or sometimes, which is a separate but related challenge facing personalized medicine.49 The use of NGS will likely continue to grow, with providers facing uncertainty as to how to integrate its use into the clinic. Studies like ours are critical and further highlight the current shortcomings in precisely interpreting results of NGS gene panels for use in clinical management.
