Thursday, September 24, 2026 11 AM-12 PM CT
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

February 2023—Atypical mitosis is considered a feature of malignancy, but its significance in breast cancer remains elusive. The authors conducted a study to assess the clinical value of atypical mitoses in breast cancer and explore their underlying molecular features. They quantified and correlated atypical and typical mitotic figures with clinicopathological variables in a large cohort of primary breast cancer tissue sections (n=846) using digitalized H&E whole slide images. They also used RNA sequencing data from The Cancer Genome Atlas (TCGA) breast cancer data set (n=1,032) to link atypical mitoses to the underlying genetic alterations and pathways.

Molecular pathology selected abstracts

February 2023—Systemic lupus erythematosus is an autoimmune disease that affects multiple organ systems and is most prevalent in women of Asian, Hispanic, and African ancestries. People with the heterogeneous disease experience major organ damage, which primarily affects the kidneys, skin, heart, and joints. Transcriptomic studies of systemic lupus erythematosus (SLE) have implicated increased type 1 interferon signaling, dysregulated lymphocyte activation, and failure of apoptotic clearance as hallmarks of the disease. Many genes are near the approximately 100 loci associated with SLE. Despite the use of flow cytometry and transcriptome profiling to characterize the role of circulating immune cells in SLE, there is not a complete census of circulating immune cells in the disease, and characterizing the genetic associations has been challenging.

Put It on the Board

February 2023—The CAP and three other organizations told the FDA in a Jan. 6 letter they are increasingly concerned that it is not recognizing updated antimicrobial susceptibility interpretive criteria, or breakpoints, in a sufficiently timely manner.
