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.

Clinical pathology selected abstracts

October 2025—Whole genome sequencing is being evaluated in newborn screening to increase the diagnosis and treatment of rare clinical conditions. Such screening raises ethical questions about which results to report and the impact of those results on parents and their children. It is important to focus on societal norms when designing whole genome sequencing–newborn screening (WGS-NBS) to make sure people accept the testing and minimize patient harm. Although parents value the fact that WGS-NBS can lead to early diagnosis and treatment of various conditions, they recognize that results may cause psychological distress, eliminate children’s autonomy, raise data-storage and privacy concerns, and lead to uncertainty regarding adult-onset medical conditions. The public, in general, supports WGS-NBS for clinically actionable childhood-onset conditions, with the caveats that health professionals are trained to interpret such results and genetic counseling is available.

Anatomic pathology selected abstracts

October 2025—Crystal-storing histiocytosis is a rare disorder in which crystals accumulate in the cytoplasm of histiocytes. It is usually associated with a lymphoplasmacytic neoplasm. Cutaneous crystal-storing histiocytosis (CSH) is extraordinarily rare and limited to case reports in the literature. The authors reported on two cases of CSH with cutaneous involvement. Case one was a 65-year-old male with a four-month history of a pruritic eruption that started as a solitary pink to skin-colored indurated plaque on the anterior neck before progressing to involve the whole neck, chest wall, and face.

Molecular pathology selected abstracts

October 2025—GATA2 deficiency is a rare inherited condition that disrupts the normal development of blood and immune cells. People born with this genetic disorder may experience low blood counts, frequent infections, or such problems as lymphedema and hearing loss. The most serious long-term risk is development of myelodysplastic syndrome (MDS), a bone marrow disorder that can progress to leukemia. The authors conducted a large study in which they followed 218 people with confirmed GATA2 mutations to understand when and how MDS develops. In this cohort, symptoms of GATA2 deficiency were present in 205 of the participants, of whom 187 (91.2 percent) had MDS.

Pathology informatics selected abstracts

October 2025—Large language models are becoming commonplace for personal and business use. The health care community is leveraging large language models (LLMs) for various purposes. Researchers at the University Medical Center Hamburg-Eppendorf, Hamburg, Germany, have successfully used open-source LLMs to extract critical medical data from pathology reports. They conducted a study that demonstrated how LLMs can transform unstructured clinical text into structured pathology data. While pathology reports are rich in information about tumor type, size, and stage, their narrative format makes automated data extraction difficult.

Q&A column

October 2025
Q. Is telepathology used much in the United States for histology interpretation and diagnosis? For example, is it used to interpret digitally transmitted histology slides when working from home? Read answer.

Q. When a patient has a hematocrit level of ≥ 55 percent and a normal PT and APTT, do you still correct sodium citrate and ask for a redraw? Is it crucial to ask for a redraw when the emergency department orders a stat PT and APTT? Read answer.

October 2025—For pathology residents, there are easier tasks than writing a perfect preliminary case report on the first attempt. Nailing Jell-O to a tree, for example, or stapling sunlight to a cloud. “When the attendings make no changes or just sign out the case as we wrote it, there’s a sense of accomplishment,” says Jingjing Cao, MD, pathology resident in the Departments of Pathology and Laboratory Medicine, University of California San Francisco.

Put It on the Board

October 2025—Send-out and other high-cost tests are the typical targets of lab stewardship, but a clinical decision support session at the ADLM meeting in July had a different focus: daily labs. It’s generally believed there is little to no opportunity for savings on daily labs because the reagent cost per test is low, as is the incremental labor savings for tests performed on automated instruments. Instead, said Grace Mahowald, MD, PhD, informatician and director of the core laboratory at Massachusetts General Hospital, “think about what goes into the cost of each of our daily lab tests,” from the nurse, patient care assistant, and phlebotomist to the specimen transporter and the lab receiving staff and technical staff who review results and call providers when specimens have to be refused at receipt. “And it’s questionable if people are even looking at the result,” she said.

From the President’s Desk

September 2025—It’s hard to believe that my two-year term as president of the CAP is already at its end. By the time you read this column, Jim Zhai, MD, will have been sworn in as our new president at the CAP annual meeting in Orlando. Serving as CAP president has given me amazing opportunities that I’m sure I would never have experienced otherwise. Perhaps the most rewarding has been the chance to meet hundreds of pathologists in the U.S. and across the globe and to witness firsthand the great work they’re doing for our profession, for the CAP, and particularly for our patients. The worldwide community of pathologists is truly impressive.

Clinical pathology selected abstracts

September 2025—Severe acute respiratory syndrome coronavirus 2 infection can lead to post-acute sequelae, or a condition known as long COVID. The World Health Organization defines long COVID as any symptoms that typically present within three months of acquiring COVID-19 and that persist for at least two months. Long COVID generally manifests as fatigue, pulmonary symptoms, and cognitive dysfunction. The biological mechanisms of long COVID are not well understood. Changes in the serotonin system may lead to cognitive changes, while mitochondrial changes may lead to fatigue, and complement and platelet activation to vascular disease.

Anatomic pathology selected abstracts

September 2025—The efficacy of human epidermal growth factor receptor 2 antibody-drug conjugate therapy for treating HER2-low breast cancers necessitates more accurate and reproducible HER2 IHC scoring. The authors conducted a study to validate the performance and utility of a fully automated artificial intelligence (AI) solution for interpreting HER2 IHC in breast carcinoma. In the two-arm multireader study of 120 HER2 IHC whole slide images from four sites, four surgical pathologists assessed HER2 scoring with and without the aid of an AI solution. Both arms of the study were compared with high-confidence ground truth established by agreement of at least four of five breast pathology subspecialists according to the American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) 2018 and 2023 guidelines. The mean interobserver agreement among the ground truth pathologists across all HER2 scores was 72.4 percent (n =120).
