University of Pittsburgh Pathologists Create World Tumor Registry to Assist Medical Professionals in the Identification and Diagnosis of Cancers

May 24, 2024 | Clinical Laboratory Middleware, Informatics, Analytics, Digital Pathology, Laboratory Instruments & Laboratory Equipment, Laboratory News, Laboratory Resources, Laboratory Testing

As the cancer registry expands it will increasing become more useful to anatomic pathologists, histopathologists, oncologists, and even clinical laboratories

Oncologists, histopathologists, anatomic pathologists, and other cancer physicians now have a powerful new Wikipedia-style tumor registry to help them with their diagnoses and in educating patients on their specific types of cancer. Clinical laboratory managers may find it useful to understand the value this searchable database, and it can help their staff pathologists as well.

Free to use by both physicians and patients the World Tumor Registry (WTR) is designed “to minimize diagnostic errors by giving doctors a searchable online database of cancers that have been collected and categorized with cellular images collected from around the world,” Pittsburg-Post Gazette reported.

Prompt, accurate cancer diagnoses offer cancer patients the best chance for optimal treatment outcomes. However, many medical professionals around the globe do not have the training and resources to offer superior cancer diagnoses. That deficiency can translate to inferior treatment options and lower survival rates among cancer patients. 

To help improve cancer diagnoses, pathologist Yuri E. Nikiforov, MD, PhD, Division Director, Molecular and Genomic Pathology, Vice Chair of the Department of Pathology,  and Professor of Pathology, University of Pittsburgh, developed the WTR to provide educational and practical resources for individuals and organizations involved in cancer research.

Officially announced at the United States and Canadian Academy of Pathology (USCAP) annual convention, the WTR is an open-access catalog of digital microscopic images of human cancer types and subtypes.

The lower cost of technology and improved speed of access via the internet are technologies enabling this effort.

“We are creating sort of a Wikipedia for cancer images,” said Alyaksandr V. Nikitski, MD, PhD (above), Research Assistant Professor of Pathology, Division of Molecular and Genomic Pathology at Pittsburg School of Medicine and Administrative Director of the WTR, in an exclusive interview with Dark Daily. “Anyone in the world, if they can access the internet, can look at the well-annotated, diagnostic digital slides of cancer,” said Nikitski. Clinical laboratories may also find this new pathology tool useful. (Photo copyright: Alyaksandr V. Nikitski)

Minimizing Diagnostic Errors

Based in Pittsburgh, the WTR is freely available to anyone for viewing digital pathology slides of known cancer tumors as well as borderline and questionable cases. On the website, individuals can search for pictures of tumors in the registry by diagnosis, specific cohorts, and by microscopic features. Individuals may search further by tumor type and subtype to receive a picture of related tumors. 

According to the WTR website, the mission of the nonprofit “is to minimize diagnostic errors, eliminate inequality in cancer recognition, diagnosis, and treatment in diverse populations, and improve outcomes by increasing access to the diagnostic pathology expertise and knowledge of microscopic characteristics of cancers that occur in different geographic, environmental, and socio-economic settings.”

This new comprehensive initiative will eventually encompass cancer images from all over the world. 

“Let’s assume that I am a pathologist or a trainee who has little experience, or I don’t have access to collections of atypical tumors,” Nikitski explained. “I can view tumor collections online [in the WTR database] and check how typical and rare tumors look in various geographic regions and environmental settings.”

Once an image of a slide is selected, users will then receive a brief case history of the tumor in addition to such data as the age of the patient, their geographic location, sex, family history of the disease, and the size and stage of the tumor.

Increasing Probability of Correct Diagnosis

Pathologists and clinicians may also predict the probability of a particular diagnosis by searching under the microscopic feature of the database. This feature utilizes an innovative classifier known as PathDxFinder, where users may compare a slide from their lab to slides in the database by certain criteria. This includes:

After completing the questions above, the user presses the “predict diagnosis” button to receive the probability of cancer and most likely diagnosis based on the answers provided in the questionnaire.

WTR Editorial Boards

The WTR represents collections for each type of cancer site, such as lung or breast. A chairperson and editorial board are responsible for reviewing submitted slides before they are placed online. The editorial boards include 20 pathologists who are experts in diagnosing cancer categories, Nikitski explained.

Thousands of identified microscopic whole slide images (WSI) representing various types of cancer are deposited by the editors and other contributors to the project. The editorial board then carefully analyzes and compiles the data before posting the images for public viewing. 

The editorial boards are located in five world regions:

  • Africa and the Middle East
  • Asia and Oceania
  • Central and South America
  • North America and Europe
  • Northern Asia

Any physicians or pathologists can contribute images to the database, by “simply selecting the editor of their region on the website, writing their name, and asking if they can submit tumor cases,” Nikitski stated.

“We have established a platform that allows pathologists to contact editors who are in the same geographic region,” he added.

Helping Physicians Identify Cancer Types 

In a YouTube video, Nikiforov states that the WTR is an “educational nonprofit organization rooted in [the] beliefs that every cancer patient deserves accurate and timely diagnosis as the first and essential step in better treatment and outcomes.”

“We believe this can be achieved only when modern diagnostic tools and technologies are freely available to every physician and pathologist. Only when we understand how microscopic features of cancer vary in different geographic, environmental and ethnic populations, and only by integrating histopathology with clinical immunohistochemical and molecular genetic information for every cancer type,” he stated.

Since patient privacy is important, the database contains only basic data about patients, and all patient information is protected.

Launched in March, there are currently more than 400 thyroid tumor slides available to view in the online database. At the time of the announcement, the WTR platform was planned to be implemented in three phases:

  • Thyroid cancer (released in March of this year).
  • Lung cancer and breast cancer (anticipated to be completed by the third quarter of 2026).
  • Remaining cancers, including brain, soft tissue and bone, colorectal, head and neck, hematolymphoid, female genital, liver, pancreatic, prostate and male genital, skin, urinary system, pediatric, other endocrine cancers, and rare cancers (anticipated to be completed by the end of 2029).

“We believe that this resource will help physicians and pathologists practicing in small or big or remote medical centers to learn how cancer looks under a microscope in their own communities,” Nikiforov said in the video. “We also see WTR as a platform that connects physicians and scientists from different parts of the world who can work together to better understand and treat cancer.”

Catalogs like the World Tumor Registry might potentially create a pool of information that that could be mined by analytical and artificial intelligence (AI) platforms to ferret out new ways to improve the diagnosis of certain types of cancer and even enable earlier diagnoses. 

“It is an extremely useful resource,” Nikitski said.

Anatomic pathologists will certainly find it so. And clinical laboratory managers may find the information useful as well when interacting with histopathologists and oncologists.

Shortage of Histopathologists in the United Kingdom Now Contributing to Record-Long Cancer-Treatment Waiting Times in England

Oct 31, 2018 | Laboratory Hiring & Human Resources, Laboratory Management and Operations, Laboratory News, Laboratory Operations, Laboratory Pathology, Laboratory Testing

Only 3% of histopathology departments that responded to the Royal College of Pathologists’ workforce census reported enough staff to meet clinical demand

There is a chronic shortage of histopathologists in the United Kingdom (UK) and it is being blamed for cancer treatment waiting times that now reach the worst-ever levels, as National Health Service (NHS) training initiatives and other steps fail to keep pace with growing demand for diagnostic services.

For US anatomic pathologists and clinical laboratory managers, headlines from the UK reveal the impact a shortage of trained histopathologists (UK’s version of anatomic pathologists) and support technical staff can have on patient care when longer wait times for pathology support and diagnosis become the norm.

Royal College of Pathologists Report

The extent of the UK-wide histopathology staff shortages was highlighted in a recently released 2017 workforce census by the Royal College of Pathologists (RCPath). Of the 103 histopathology departments that responded to a survey, only 3% said they had enough staff to meet the current clinical demand! And 45% of departments had to outsource work, while half of the departments were forced to use more expensive temporary workers.

“The cost of staff shortages across histopathology departments is high for both patients and for our health services,” Jo Martin, PhD, President of the Royal College of Pathologists, noted in a statement announcing the survey results. “For patients, it means worrying delays in diagnosis and treatment. For NHS hospitals, it means spending more resources on [temporary] doctors to fill staffing gaps, or outsourcing services. We estimate this cost [to be] £27 million ($35.2 million) each year across the UK health service—money that could be better invested in staff and new diagnostic equipment.”

Royal College of Pathologists President Jo Martin, PhD, is calling on the National Health Service to take additional steps to increase the number of pathologists working in the United Kingdom, including more funded training places. That’s following the release of a Royal College of Pathologists workforce survey, which reported only 3% of histopathology departments in the UK have enough staff to meet clinical demand.

According to iNews, NHS England recorded its worst cancer treatment waiting times on record in July 2018, with more than 3,000 people waiting longer than two months for cancer treatment to begin. NHS’ target is for 85% of patients to begin cancer treatment within 62 days of being referred by their general practitioner.

Anatomic pathologists in the United States should consider how the UK’s average delay in starting cancer treatment affects patients in that country. It is a metric that patients in the US would not tolerate. However, in the UK’s single payer system, the government’s National Health Service sets the budgets for training new physicians, including histopathologists. For many years, the pathology profession in the UK has regularly advocated for increasing the number of histopathologists trained each year by the medical schools in that country.

In July, the number of patients waiting for treatment longer than 60 days fell to 78.2%, the 31st month in a row the target was breached, iNews reported.

“We know that histopathology consultant shortages contribute to at least part of that problem,” Martin told iNews.

The RCPath report highlights the intense pressures on histopathologists—most of whom working in understaffed laboratories—face from increased workloads, as new NHS cancer screening initiatives, an aging population, and a shift toward precision medicine result in a rising number of cases being referred to labs.

“Demand for pathology services has grown significantly in recent years and continues to grow,” Martin noted in the RCPath statement. “The pathology workforce has not increased in line with this demand. If this trend continues unchecked, clinical services could be in jeopardy. Making sure pathology services can cope with current and future demand is essential if we are to ensure early diagnosis and improve outcomes for patients.”

Lack/Loss of Trained Histopathologists an Ongoing Problem

This is not the first time the alarm has been sounded in the UK over the lack of investment in trained pathologists along with a growing shortage of trained professional staff. In 2017, Dark Daily reported on calls by pathologists and other physicians for the UK government to increase funding for trained medical laboratory professionals to avert a predicted critical shortage in laboratory staffing within the next decade. (See “Pathologists and Physicians in United Kingdom Comment on How Shortage of Medical Laboratory Professionals Could Soon Delay Essential Diagnostic, Therapeutic Testing,” February 6, 2017.)

In its most recent workforce report, The Royal College of Pathologists is reiterating its call for:

  • Increased funding for training;
  • Better information technology (IT) for day-to-day work;
  • Capital investment to implement digital pathology more widely; and,
  • Development of advanced clinical practitioner apprenticeships to help more biomedical scientists become independent practitioners who would work alongside medically-qualified histopathologists.

Long-term, the organization is calling for additional training slots for pathologists in universities as well as other changes to draw more scientists into the field.

Aging Pathology Staff Means Shortages in US a Possibility

The NHS has stopped short of declaring the pathologist shortage a crisis. Instead, a Department of Health and Social Care spokesperson in an interview with the BBC highlighted recent initiatives taken in response to the shortage. “There are hundreds more pathologists in the NHS compared to 2010 and hospitals have reduced spending on temporary agency staff by over half a billion pounds in the last year,” the spokesperson noted. “We are listening to staff, encouraging more flexible working, and have increased medical training places for home-grown doctors by 25%, to ensure the NHS has the workforce it needs for the future.”

Despite those steps, the NHS may have more work to do. According to the Royal College of Pathologists workplace survey, a quarter of all histopathologists in the UK are 55 or older, adding an approaching retirement crisis to the existing shortage.

US anatomic pathology groups and clinical laboratories should monitor these events with a keen eye. The American pathology industry is challenged by many of the same trends, such as an aging workforce and lackluster replacement initiatives. Time will tell if the US learns from the UK’s experience.
