This is Part 3 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 first-line treatment of metastatic colon cancer. The patient is a 48-year-old man who presents to his primary care provider with bloody diarrhea. Colonoscopy reveals a nonobstructing sigmoid colon tumor, which pathology confirms as adenocarcinoma. CT of the chest, abdomen, and pelvis reveals a liver mass and multiple bilateral pulmonary nodules, and he is diagnosed with metastatic adenocarcinoma. His ECOG performance status score is 1, and he is started immediately on FOLFOX chemotherapy. Meanwhile, next-generation sequencing is ordered, which reveals APC and TP53 mutations, and wild-type KRAS, NRAS, and BRAF. The faculty discuss the myriad treatment options for this relatively young and fit patient with left-sided RAS wild-type metastatic colon cancer. They review the impact of tumor sidedness on decision making in the front-line setting, as well as the clinical implications of the recent phase III PARADIGM study.
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.
This is Part 1 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 HER2-positive metastatic colorectal cancer. The patient is a 49-year-old man who presents to the ER with nausea, vomiting, and abdominal pain. A CT of the chest, abdomen, and pelvis reveals bowel obstruction, extensive hepatic metastases, and abdominal lymphadenopathy, and a partially obstructing mass in the sigmoid colon is found on colonoscopy. Next-generation sequencing is ordered, and the patient has APC and TP53 mutations, as well as an ERBB2 amplification. The faculty discuss potential next steps for a patient such as this, highlighting the role of HER2 amplification/overexpression in metastatic colorectal cancer, how the presence of brain metastases impacts treatment decisions, and treatment options for patients whose disease progresses on prior anti-HER2 therapies.
