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.

April 2024

Clinical pathology selected abstracts

April 2024—Neonatal anemia is a common comorbidity of premature infants and may result from certain obstetric conditions or diseases, or, in the case of iatrogenic anemia, from multiple phlebotomies in the first days of life. Once infants enter the neonatal intensive care unit (NICU), they undergo a series of laboratory tests at baseline and then as needed for treatment or monitoring. These tests commonly include blood cultures, CBCs, coagulation profiles, metabolic screens, blood gases, blood glucose, and chemistry profiles. Phlebotomy-associated blood loss is more clinically relevant in lower birth-weight neonates since they have lower total circulating blood volumes. When blood is drawn from an indwelling umbilical catheter, even more blood is removed due to the need to flush residual intravenous fluid from the line.

Anatomic pathology selected abstracts

April 2024—Fumarate hydratase-deficient renal cell carcinoma is a rare and distinct subtype of renal cancer caused by FH gene mutations. FH negativity and s-2-succinocysteine (2SC) positivity on IHC can be used to screen for FH-deficient renal cell carcinoma (RCC), but their sensitivity and specificity are imperfect. The expression of AKR1B10, an aldo-keto reductase that catalyzes cofactor-dependent oxidation-reduction reactions, in RCC is unclear. The authors compared AKR1B10, 2SC, and FH as diagnostic biomarkers for FH-deficient RCC. They included genetically confirmed FH-deficient RCCs (n=58), genetically confirmed TFE3 translocation RCCs (TFE3-tRCC; n=83), clear cell RCCs (n=188), chromophobe RCCs (n=128), and papillary RCCs (pRCC; n=97).

Molecular pathology selected abstracts

April 2024—Personalized medicine is revolutionizing cancer therapy, with targeted treatments customized to a person’s cancer-specific mutational profile leading to substantially improved health outcomes. Personalized medicine can also be applied to cancer prevention for high-risk groups based on genetic predisposition or lifestyle factors. However, there is a significant gap in cancer research resulting from a lack of equitable representation of racial and ethnic groups in cancer databases. Most research data are derived from white patients in the United States and Europe, creating racial disparities in understanding cancer development and therapies. The underrepresentation of patients of African, Asian, and Native American descent in observational, translational, and clinical cancer studies is particularly notable.

April 2024—Transitioning to digital pathology can seem complex and costly. And for some, but not all, laboratories, cost in particular can be a barrier to adoption. So how do you determine which camp your lab falls into? You calculate, according to Orly Ardon, PhD, director of digital pathology operations at Memorial Sloan Kettering Cancer Center.

Q&A column

April 2024
Q. Ordering clinicians are requesting that our laboratory flag abnormally high absolute neutrophil counts (ANC) on peritoneal fluids. We cannot find sources for reference ranges, but there is literature that states that a polymorphonuclear cell count greater than 250/μL is a reliable discriminatory test for bacterial peritonitis. We would like to use this as our reference and flag results with an ANC greater than 250 cells/μL as abnormally high. Is this acceptable? Read answer.

Q. How do you code fallopian tubes submitted for sterilization with a finding of a paratubal cyst? Read answer.

Letters

April 2024—The article “Test adds twists to lung disease diagnosis” (November 2023, page 1) virtually ignores the major problem of clinicians in the hospital thinking that it is perfectly okay to take specimens from patients in the hospital and send them directly to whatever laboratory they choose without input from the hospital’s laboratory administration or medical director. The laboratory medical director is legally responsible for approving the menu of laboratory tests to be performed in-house and all of the reference laboratories to be used.

April 2024—Member organizations of the Enduring Consensus Cervical Cancer Screening and Management Guidelines effort released in March their recommendations for the use of p16/Ki-67 dual stain for managing individuals who test positive for HPV.
