This session explores the evolving role of RAS in precision oncology, from the biology of RAS mutations to the expanding landscape of targeted therapies. Through expert presentations, real-world case discussions, and interactive audience polling, participants will examine best practices for RAS biomarker testing across solid tumors, including lung, colorectal, and pancreatic cancers. The session will highlight practical considerations for tissue and liquid biopsy, strategies to address testing gaps, and the importance of multidisciplinary collaboration to ensure timely identification of patients who may benefit from RAS-targeted therapies.

September 2025—When someone dies suddenly and unexpectedly, a forensic autopsy is often performed to identify the manner and cause of death. However, up to 30 percent of autopsies fail to identify any underlying anatomic or toxicologic etiologies, and the autopsy classification may be sudden unexplained death. This is particularly concerning in young people, in whom the cause could be an inherited genetic condition that could also affect family members. Therefore, postmortem genetic testing, also known as a molecular autopsy, may have utility in identifying underlying inherited diseases that could contribute to death. In many cases, sudden death is due to cardiac factors, but the type of cardiac dysfunction may depend on age.

Q&A column

September 2025
Q. Some of my laboratory staff are reluctant to reach out to the CAP with accreditation questions on checklist requirements because they fear that doing so will lead CAP inspectors to scrutinize those related items more closely during the next inspection. How does the College manage information from these phone calls? Read answer.

Q. An oncologist recently told me to perform a platelet count on a sodium citrate (blue top) tube even though the platelet results from the EDTA tube were valid—no platelet flags, a Q-flag value of zero, a normal platelet histogram, and no clumps seen on slide review. Based on this evidence, this patient is not an EDTA clumper and using the blue-top tube isn’t indicated or recommended, as far as I know. What is the science behind this request? There were platelet clumps in the blue-top tubes (platelet instrument flags and clumps seen on the slides from the citrate tubes), which further invalidated these results in my opinion as a licensed laboratory scientist. Read answer.

September 2025—In his previous role as a pathologist at Seattle’s Virginia Mason Medical Center, Dick Hwang, MD, PhD, was looking for a way to make his life—and his colleagues’ lives—easier. So he reached for something he hadn’t used in a while: his doctorate in computational biology. It was 2014, and Virginia Mason’s pathology group had just rolled out M*Modal Fluency Direct speech-recognition software as an optional tool for dictating diagnostic data. Dr. Hwang and many of his colleagues embraced the new software, but they soon realized that it meant they’d be spending a lot of time editing and formatting data. Entering a final diagnosis required, for example, typing “1.{tab}{caps lock},” dictating “cecum and ascending colon comma polypectomy,” then typing “:{caps lock}{return}{backspace}A.{tab}”—just as a start.

Put It on the Board

September 2025—CAP president Donald Karcher, MD, in a July 25 letter urged the chairs and ranking members of the Senate and House appropriations subcommittee on labor, health and human services, education, and related agencies to apply pressure to obligate and award already approved funding for the CDC Division of Cancer Prevention and Control. “Even though Congress approved FY 2025 funding in March, the CDC has not issued notice of awards to provide funding to state and local health departments for the remaining FY 2025 funds,” he said. “State and local health departments are challenged to continue their work without knowing if they will be reimbursed. State health departments and grantees are on the verge of shutting down programs and furloughing staff.”

Letters

September 2025—It has come to the attention of the American Association of Pathologists’ Assistants that some pathologists and pathology fellows assume the pathologists’ assistant profession is widely licensed, since we are comparable to the nationally licensed physician associates. This is a misconception that I, chair of the AAPA legislative subcommittee, and the AAPA Board of Trustees would like to address with the pathology community.

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.

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.
