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.

Anatomic pathology selected abstracts

December 2020—It can be difficult to distinguish metastatic melanoma from melanocytic nevi in lymph nodes. Because diffuse IHC PRAME (preferentially expressed antigen in melanoma) expression is detected in the majority of primary and metastatic melanomas, but rarely in nevi, the authors conducted a study in which they hypothesized that PRAME could be a useful adjunct marker for the diagnosis of melanocytes in lymph nodes. They examined 45 nodal melanocytic deposits comprising 30 nodal nevi and 15 melanoma metastases. The latter were not straightforward from a diagnostic perspective because they coexisted with nodal nevi or were present in perinodal fibrous tissue. All nodal nevi were negative for PRAME and all melanoma metastases were diffusely positive for PRAME IHC.

Molecular pathology selected abstracts

December 2020—Next-generation sequencing-based mutation testing of various cancer types is clinically indicated and widely used to diagnose disease, inform potential therapeutic targets, prognosticate disease course, and monitor responses to targeted and nontargeted therapies. The genetic variants discovered by tumor-based next-generation sequencing (NGS) can be somatically acquired by the neoplastic cells or a fixed inherited component of the patient’s germline genome. Distinguishing the germline versus somatic status of tumor NGS-defined variants is of significant clinical importance not only for patient care but possibly for patients’ families. Because many cancers have a substantial inherited component, the discovery of a pathogenic germline mutation by tumor-based NGS may have substantial familial implications. For example, being aware of a cancer risk allele, such as BRCA1, can lead to the use of highly effective interventions to prevent or treat the related cancer in family members. Consensus guidelines recommend germline genetic testing only for those cancer patients who have a clinical presentation or family history suggestive of hereditary disease.

Q&A column

Q. Can a heel stick for a basic metabolic panel with magnesium and phosphorus be performed on a two-month-old baby? Read answer.
Q. Due to nationwide supply shortages affecting COVID-19 and other testing in the laboratory, we are concerned about using up critical supplies when assessing competency. Do you have suggestions or strategies we can use? Read answer.
Q. When a patient is admitted to our hospital, we collect MRSA nares PCR, MRSA axilla by culture, MRSA groin by culture, and vancomycin-resistant Enterococcus by PCR for infection control purposes. Many surrounding facilities have told us they have removed the axilla and groin cultures, but no references were cited to support removing these procedures. Our facility would like to follow the practices of other hospitals, but our providers would like a reference to cite.

Are there best practices or benchmarks from an infection control and microbiology point of view that would allow us to remove the axilla and groin MRSA screen cultures? Read answer.

New NovoPath CEO settled in and taking questions
December 2020—CAP TODAY publisher Bob McGonnagle recently spoke with Promise Okeke, who took the helm as CEO of NovoPath last summer. Here’s what Okeke had to say about NovoPath’s case distribution module, customer service, and the advantages of offering a best-of-breed system, among other topics.

December 2020—Antimicrobial Susceptibility Testing: Monitoring and Trend Analysis is a new CAP program that is beginning to roll out to laboratories this month. The CDC guidance for antibiotic stewardship consists of seven core elements to address resistance-associated risks, one of which points to the importance of laboratory collaboration, communication, and AST reporting practices to the success of stewardship programs. According to this core element, the laboratory must provide information to guide discussions on the potential implementation of test interpretive criteria, such as changes in antibiotic breakpoints, that might affect antibiotic use.
