Columns

From the President’s Desk

August 2025—I’ve written in this column many times that pathologists should be leaders of the laboratory. But all of the leadership skills we develop through that role also make us a good fit for many other leadership positions in our health care institutions and beyond. I have met CAP members who are chief medical officers, chief quality officers, presidents of their medical staff, and even CEOs of hospitals and health care networks. The current commander of one of the largest military medical centers in the U.S. is a pathologist.

Clinical pathology selected abstracts

August 2025—The Accreditation Council for Graduate Medical Education (ACGME) oversees graduate medical education and closely monitors resident wellness. In 2017, the ACGME published findings from a national study outlining the causes of death among residents and fellows from 2000 through 2014. The most common overall cause of death was malignant neoplasm, and it was the leading cause of death among female residents and fellows. Suicide was the leading cause of death for male residents and the second leading cause for females. Twenty-three percent of deaths by suicide occurred in the first academic quarter of trainees’ first year in their medical programs.

Anatomic pathology selected abstracts

August 2025—Certain subtypes of colorectal carcinoma pose diagnostic challenges in daily practice due to sometimes overlapping morphologic and immunohistochemical features and are associated with worse prognoses than poorly differentiated adenocarcinoma not otherwise specified (PDA-NOS). Other variants of poorly differentiated colon cancers with solid growth patterns that have, anecdotally, been recognized as posing diagnostic challenges include large cell neuroendocrine carcinoma (LCNEC), medullary carcinoma (MC), undifferentiated carcinoma (UC), and lymphoepithelioma-like carcinoma (LELC). The authors conducted a study to determine survival outcomes between patients with poorly differentiated adenocarcinoma and those with a variant carcinoma morphology that may affect prognosis. They also analyzed interobserver agreement among gastrointestinal pathologists at their institution in subclassifying poorly differentiated colorectal carcinoma. All consecutive patients with diagnoses of PDA-NOS, MC, LCNEC, UC, and LELC between July 2018 and July 2023 were included.

Newsbytes

August 2025—Recognizing the value of researching options before purchasing a big-ticket item, the College of American Pathologists has developed the AI Playground to help pathologists assess artificial intelligence tools before going all-in on a technology that may not end up suiting their needs, among other potential issues. The playground will offer cutting-edge AI tools that pathologists can test-drive from the comfort of their own laboratories using simulated data sets on a platform designed specifically for that purpose. It will be available to CAP members at no charge and accessible via the CAP website after it is debuted in the CAP Innovation Hub and the College’s booth at CAP25, in Orlando, next month.

Molecular pathology selected abstracts

August 2025—Childhood malignancies such as Wilms tumor—the most common type of kidney cancer in children—exhibit very few DNA changes when tested by traditional sequencing methods. Some of these types of tumors have fewer genetic anomalies than age-matched normal tissue. This raises the question, How can such genetically “quiet” malignancies emerge and progress without conventional driver mutations? To address this question, the authors employed high-resolution, ultra-deep sequencing to determine if hypomutation in juvenile kidney cancers characterized by a paucity of mutations, specifically Wilms tumor, is genuine or an artifact of conventional analytical constraints. By applying high-resolution duplex sequencing (Nanoseq) to Wilms tumors and matched normal kidneys from six pediatric patients, including four infants and two school-age children, the authors showed that standard bulk whole genome sequencing significantly underestimates the mutational burden in tumors from infants.

Q&A column

August 2025
Q. We manage multispecialty laboratories in multiple hospital locations. Most of the laboratories function on the traditional model of compartmentalized specialty-based testing units that offer routine and specialized services with their own dedicated space, equipment, and personnel. There is a future plan to establish an offsite centralized referral lab, but to improve operational efficiency and cost savings sooner, management is considering consolidating testing services at each location. What factors should be considered while planning the consolidation, keeping in mind the plan to establish a centralized reference lab? Should the testing services that will eventually be performed in the reference lab be excluded from the current consolidation plan? And how should we manage operations during the transition phase, i.e. once consolidation is completed but prior to the reference lab implementation? Read answer.

Q. We have been discussing supervisory review of test results that are manually entered into our laboratory information system (i.e. a test result not sent via interface from an analyzer or autoverified). Examples are a urine hCG performed on a kit cassette or a manual differential performed on a CBC, entered directly into the LIS by the performing technologist. Do manual test results require supervisory review, or is it only higher-complexity tests (like the differential) performed by a medical laboratory technologist that require such review? If review is required, who can review and what is the recommended time frame? Read answer.

Put It on the Board

August 2025—In a position statement released in July, the CAP urged policymakers to consider scientific and logistical evidence and to protect the integrity and safety of the national blood supply. The statement was issued in response to legislation proposed in several states that would require blood product labeling based on donor vaccination status or mandate hospitals and blood collectors to honor requests for directed and autologous donations. Misinformation surrounding COVID-19 and mRNA vaccines has led to a growing number of patient requests for blood transfusions exclusively from unvaccinated donors.

Shorts on Standards: ISO/TS 23824 can help take anatomic pathology quality to another level

July 2025—The International Organization for Standardization (ISO) published a new technical specification, ISO/TS 23824 (Medical Laboratories—Guidance on Application of ISO 15189 in Anatomic Pathology), on the application of ISO 15189 to anatomic pathology. Although structured around the clauses of ISO 15189, the document offers useful guidance, ideas, and concepts applicable to any AP laboratory, including every AP laboratory in the United States that has to comply with CLIA ’88 or CAP Laboratory Accreditation Program requirements.

From the President’s Desk

July 2025—Whether we’re in academic or private practice, hospital labs or independent labs, as pathologists we share a broad set of common responsibilities and challenges. But a select group of us has an additional set of considerations for how to practice because of who and where they serve. In this month’s column, I’d like to shine a light on military pathologists and pathologists who serve our veterans in the Veterans Affairs health system—all of whom are supporting the defense of our country.

July 2025—A large number of cancers remain undetected until later stages, including lung, colorectal, cervical, ovarian, pancreatic, and prostate cancers. The U.S. Preventive Services Task Force recommends screening based on age and other risk factors. It is estimated that more than 4 million cancers have been avoided due to early screening methods. Efforts are being made to develop cancer-screening tests that are easier to perform and less invasive and that detect multiple types of cancer, with the intent of reducing cancer-related morbidity and mortality. Multicancer early detection (MCED) assays depend on circulating cell-free DNA to detect a shared single cancer signal.
