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.

February 2021

Clinical pathology selected abstracts

February 2020—SARS-CoV-2 is transmitted through respiratory droplets, close person-to-person contact, and infected surfaces. Those with COVID-19 often present with fever and respiratory symptoms, and diagnosis relies on detecting the virus through specimens from the upper and lower respiratory tract. However, an increasing number of patients are exhibiting such gastrointestinal symptoms as diarrhea, vomiting, and abdominal pain. A growing number of studies are reporting the presence of SARS-CoV-2 RNA in stool samples and anal swabs, generating interest in research focused on a fecal-oral route of transmission. The authors conducted a study to assess the clinical relevance of testing stool samples and anal swabs for SARS-CoV-2 and to provide a critical overview of literature addressing possible fecal-oral transmission.

Anatomic pathology selected abstracts

February 2021—SARS-CoV-2 primarily causes pulmonary injury, but it has been implicated in hepatic injury through the use of serum markers and histologic evaluation. The histologic pattern of injury has not been completely described, and studies quantifying viral load in the liver are lacking. The authors conducted a study in which they reported the clinical and histologic findings related to the liver in 40 patients who died of complications of COVID-19. For the study, they subjected a subset of liver tissue blocks to polymerase chain reaction (PCR) for viral RNA. Peak levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated, with a median ALT peak of 68 U/L (normal up to 46 U/L) and median AST peak of 102 U/L (normal up to 37 U/L). Macrovesicular steatosis was the most common finding, involving 30 (75 percent) patients.

Molecular pathology selected abstracts

February 2021—Beta-thalassemia and sickle cell disease are common hereditary conditions that can have life-threatening complications. Both diseases are caused by genetic alterations affecting the beta subunit of hemoglobin. Mutations that reduce or prevent the synthesis of the beta-globin protein cause beta-thalassemia, a disease characterized by inadequate red blood cell production and, therefore, anemia. In contrast, sickle cell anemia results from a specific point mutation in the beta-globin gene that causes the resulting protein to polymerize. These protein polymers form rigid fibers that affect the stability of the red blood cell and cause its characteristic sickling deformity. Destruction of the aberrant red blood cells leads to anemia, and the sickled cells can also cause painful vaso-occlusive episodes and tissue damage.

Q&A column

Q.
 Can toxicology testing be performed on a person who has been deceased for two years? Read answer.
Q. Is there a standardized procedure for performing platelet estimates that incorporates the dilution effect for low hemoglobin in anemic patients? The formula I found for platelet estimation works well with low hemoglobin levels but not with levels greater than 13 g/dL. Read answer.
