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.

Abstracts

Molecular pathology selected abstracts

Personalized oligonucleotide therapy for treatment of a rare genetic disease
December 2019—A variety of molecular diagnostic laboratory tools are available to diagnose diseases caused by mutations in the human genome. However, few treatments are available to correct the underlying pathophysiology driven by these mutations. This is due, in part, to pharmaceutical companies’ inability to justify, from a business perspective, the expense and time necessary to develop and obtain FDA approval for novel therapies that benefit only a small number of patients.

Clinical pathology selected abstracts

Intensive versus standard blood pressure control with cerebral white matter lesions
November 2019—The effect of intensive systolic blood pressure control on brain health is uncertain, despite its efficacy for reducing cardiovascular morbidity and mortality. However, hypertension is a primary risk factor for cerebral small vessel ischemic disease (SVID), especially in developing white matter lesions (WML). The pathogenesis of Alzheimer disease and related dementia is known to be associated with SVID and cognitive decline.

Angiosarcoma of the liver: clinicopathologic features and morphologic patterns
November 2019—Angiosarcoma is a rare malignant neoplasm of the liver for which morphologic patterns have not been systematically studied. To provide more comprehensive data on morphologic patterns, the authors reviewed angiosarcomas that had been diagnosed between 1996 and 2016 at a large medical referral center. The major growth patterns were classified as sinusoidal (nonmass forming) or mass forming.

Anatomic pathology selected abstracts

April 2019—Frequent GNAQ and GNA14 mutations in hepatic small vessel neoplasm: April 2019—Hepatic small vessel neoplasm is a recently described infiltrative vascular neoplasm of the liver composed of small vessels. Although its infiltrative nature can mimic angiosarcoma, hepatic small vessel neoplasms (HSVNs) are thought to be benign or low-grade neoplasms because they lack cytologic atypia and increased proliferation.

Molecular pathology selected abstracts

April 2019—Variants in NUDT15: association with thiopurine–induced myelosuppression: The thiopurines mercaptopurine, thioguanine, and azathioprine are purine antimetabolites widely used as anticancer and immunosuppressive agents. Commonly prescribed in patients with inflammatory bowel diseases (IBD), such as Crohn’s disease and ulcerative colitis, they are valuable steroid-sparing treatment options.

Clinical pathology selected abstracts

March 2019—Evaluation of ethanol interference on routine biochemical tests: Ethanol, a central nervous system depressant widely consumed in many societies, is metabolized in the liver through multiple enzymatic pathways. If the liver’s capacity is exceeded, the excess alcohol will flood into the systemic circulation.

Anatomic pathology selected abstracts

March 2019—ALK expression in angiomatoid fibrous histiocytoma: a potential diagnostic pitfall:
The authors recently encountered a case of primary pulmonary angiomatoid fibrous histiocytoma (AFH), which was initially misdiagnosed as inflammatory myofibroblastic tumor based in part on anaplastic lymphoma kinase expression by IHC. Prompted by this experience, they evaluated anaplastic lymphoma kinase (ALK) expression in 11 AFH, 15 inflammatory myofibroblastic tumors (IMT), and 11 follicular dendritic cell sarcomas using three antibody clones: D5F3, 5A4, and ALK1.

Molecular pathology selected abstracts

March 2019—Using circulating cell-free fetal DNA to test for monogenic disorders: Screening for fetal chromosomal abnormalities can be performed by noninvasive methods in which fetal cell-free DNA (cfDNA) circulating in the maternal blood is isolated and analyzed. However, the standard of care for screening for monogenic diseases remains population-based carrier screening—testing the parents for their carrier status of deleterious genes.

Clinical pathology selected abstracts

February 2019—Impact of commercial laboratory testing on a care delivery system: Care delivery systems have become increasingly fragmented and complex, which impacts patient care. The amount of health care data generated has also created a problem by reducing the time devoted to direct patient care.

Anatomic pathology selected abstracts

February 2019—Diagnostic algorithmic proposal based on IHC evaluation of invasive endocervical adenocarcinomas: The International Endocervical Adenocarcinoma Criteria and Classification was developed to separate endocervical adenocarcinomas into two main categories based on morphology: human papilloma virus-associated (HPVA) and nonhuman papilloma virus-associated adenocarcinomas.
