According to the American Cancer Society, colorectal cancer is the second-leading cause of cancer-related death in the United States. In 2023, the disease is expected to cause an estimated 52,550 deaths. Studies show that receiving a clinician recommendation is the strongest and most consistent...
This is Part 3 of New Directions in Metastatic Colorectal Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Michael Overman, Laura Goff, and Katrina Pedersen discuss later-line treatment options for metastatic colorectal cancer. The patient is a 64-year-old male with metastatic ascending colon moderately differentiated adenocarcinoma. On CT scan, he has liver, lung, and retroperitoneal lymph node metastases. Molecular testing demonstrates proficient mismatch repair, HER2 IHC negative; a 100-gene next-generation sequencing panel demonstrates KRAS G13D, PIK3CA, CCND2, and ATM mutations. The patient has a good performance status and is initiated on FOLFOXIRI/bevacizumab with partial response, then develops disease progression on fluorouracil/bevacizumab maintenance therapy. The faculty review the next steps for this patient and the importance of quality-of-life considerations when making treatment decisions. They also discuss the evolving third-line landscape, highlighting the recent SUNLIGHT trial that evaluated the addition of bevacizumab to TAS-102.
This is Part 2 of New Directions in Metastatic Colorectal Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Michael Overman, Laura Goff, and Katrina Pedersen discuss second-line treatment options for metastatic colorectal cancer. The patient is a 46-year-old female with locally advanced, poorly differentiated rectal adenocarcinoma who received neoadjuvant chemoradiation followed by resection, which revealed a ypT4N1 tumor. She received adjuvant FOLFOX for eight cycles; 5 months after completion of therapy, a restaging CT scan revealed more than 10 growing pulmonary nodules, all < 1 cm. In the conversation that follows, the faculty discuss the many treatment options available in the second-line setting, the factors that impact decision-making, and the emerging role of HER2 amplification/overexpression as an actionable target in metastatic colorectal cancer.

This is Part 1 of New Directions in Metastatic Colorectal Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Michael Overman, Laura Goff, and Katrina Pedersen discuss front-line treatment options for metastatic colorectal cancer. The patient is a 77-year-old male with a history of resected prostate cancer who developed rectal bleeding. He had a colonoscopy in 2016 that revealed a transverse T3N1 adenocarcinoma that was subsequently resected. After four cycles of FOLFOX, he developed chest pain that led to a CT scan demonstrating left supraclavicular adenopathy. A biopsy is performed, and CT scan shows liver and adrenal metastases. In the conversation that follows, the faculty discuss the next steps for this patient, the importance of mismatch repair testing in the decision-making process, and the role of monotherapy vs combination therapy.
