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.

Webinar presenters David Braxton, MD, Chief of Molecular Pathology Services, Hoag Family Cancer Institute & Hoag Memorial Hospital Presbyterian, and Carlos Becerra, MD, Research Director for Medical Oncology, Margaret Given Larkin Endowed Chair for Developmental Cancer Therapeutics, Hoag Memorial Hospital Presbyterian.

July 2021

From the President’s Desk: ‘Divided we fall’

July 2021—It has been a long time since the American public has been so terribly divided by politics. So many topics seem polarizing in our country right now. As pathologists, we should not allow these forces to fragment us. I fear that if we are not careful, we could find our community pulled apart, and that would be detrimental to those we should most protect—our patients. I’ve been thinking a lot lately about the phrase, “United we stand, divided we fall.” It is well worn but still meaningful. It’s the official motto of the Commonwealth of Kentucky, where I was born. Within the CAP and each state’s pathology society—in my view, the two groups every pathologist should belong to—it is imperative that we stick to the topics that unite us to keep our organizations strong and inclusive. We are all pathologists or soon-to-be pathologists, and we are all physicians. We are united on measures that allow us to better serve our patients and protect our practices. We should not be divided by politics, and there is no room for that in the CAP or state-level pathology societies. I am not saying that we should not individually be politically active or work peacefully in other politically active groups.

Clinical pathology selected abstracts

July 2021—Pathologists play a key role in molecular and genomics testing, so pathologists-in-training should demonstrate an understanding of genetics concepts and the utility of molecular and genomic testing in patient care. A list of published competencies for training includes determining sample adequacy, ensuring that appropriate molecular tests are ordered, and effectively communicating genomic testing results through pathology reports and interdisciplinary teams.

Anatomic pathology selected abstracts

July 2021—Microscopic colitis is characterized by chronic watery diarrhea, endoscopically normal findings, and abnormal histology. The disorder is most prevalent in adults. Pediatric cases are rare and may vary in presentation.

Pathology informatics selected abstracts

July 2021—Despite growing awareness of whole slide imaging, few pathology laboratories have implemented and validated such a digital pathology system for primary diagnosis. Among the barriers to adopting whole slide imaging (WSI) for routine clinical work is the difficulty of justifying the expense, time and effort, and change management involved in deploying this disruptive technology.

Molecular pathology selected abstracts

July 2021—The accurate diagnosis of malignant pleural mesothelioma is important because of its association with asbestos inhalation and because it is an aggressive tumor with poor outcome despite multimodal treatment. Unfortunately, however, diagnosing malignant pleural mesothelioma is not straightforward. Initial diagnosis often occurs on small biopsies, and the disease has morphologic overlap not only with other neoplasms that affect the lungs and pleura, such as solitary fibrous tumor or synovial sarcoma, but also with reactive conditions, such as reactive mesothelial hyperplasia or sclerosing fibrous pleuritis. While immunohistochemical markers can provide ancillary information, many of them are nonspecific and can lead to diagnostic dilemmas. Sequencing of cancer genes can help in some situations but cannot provide a definitive diagnosis.

Q&A column

July 2021
Q. Our lab does not have reference ranges established for body fluid manual differentials. Is it acceptable to use ranges from a reference material and include a disclaimer citing the source of the ranges? Read answer.
Q. In our lab, we perform semen analysis and make slides to send out for sperm morphology using Kruger’s strict criteria. We get quite a few results back as swollen sperm head for probable contamination. The reference lab insisted that liquefying agent was added, but when we reviewed the results, the sample was normal, so liquefying agent wasn’t used. What can cause a sperm head to swell, other than liquefying agent? Read answer.

July 2021—As the role of informatics in the practice of medicine continues to grow, so does the need to move formalized informatics education from the category of luxury to necessity, says Bruce Levy, MD, associate chief medical informatics officer at Geisinger Health System, Danville, Pa., and professor and program director of the clinical informatics fellowship at Geisinger Commonwealth School of Medicine.

Letters

July 2021—The article about eGFR (“A transparent lens on estimated GFR,” June 2021) reinforces my initial attitude about eGFR: that it is an inaccurate contrived calculation. Testing for the status of a patient’s renal function is information too crucial to be done as a shortcut even though the National Kidney Foundation claims that eGFR is the most accurate way of determining renal function.

Put It on the Board

July 2021—The FDA in May approved two new targeted therapies for non-small cell lung cancer.
