BRAF V600E–Mutated Colon Cancer

This is Part 2 of The Evolving Targeted Treatment Landscape for Colorectal Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable.   In this video, Drs. John Strickler, Stacey A. Cohen, and Harshabad Singh discuss the management of BRAF V600E–mutated colorectal cancer. The patient is a 40-year-old woman who presents to the ER with severe abdominal pain. CT scan of the chest, abdomen, and pelvis reveals a cecal mass with adjacent nodularity, abdominal lymphadenopathy, and multiple liver lesions consistent with metastatic disease. Colonoscopy demonstrates a nonobstructing mass in the ascending colon; pathology confirms adenocarcinoma, and biopsy of liver lesion confirms adenocarcinoma consistent with colorectal primary. Her performance status is limited due to severe abdominal pain related to her metastatic disease. The patient is started on FOLFOX plus bevacizumab, which results in an improvement in her pain and performance status. Next-generation sequencing reveals APC, SMAD4, and TP53 mutations, as well as a BRAF V600E mutation.   The faculty discuss the treatment options for patients with aggressive BRAF V600E mutations, which are associated with poor prognosis and EGFR resistance, in both the first- and second-line setting. They also highlight importance of individualizing treatment based on a patient’s age, performance status, goals of treatment, and comorbidities.
