Multidisciplinary Care and New Treatment Options in CRC

Kristen K. Ciombor, MD, MSCI, an assistant professor in the Division of Hematology/Oncology in the Department of Medicine at the Vanderbilt University Medical Center, recently spoke at an Around the Practice discussion regarding updates in the world of metastatic colorectal cancer (CRC).

In this episode of the ONCOLOGY® On the Go Podcast, she discusses treatment updates, molecular testing options, and emerging targets in CRC. Ciombor also highlighted ongoing research in the space, including the phase 3 BREAKWATER (NCT04607421)¹ trial and the phase 3 MOUNTAINEER-03 (NCT05253651)² trial. She also discussed some of the most important presentations from the 2023 European Society for Medical Oncology (ESMO) Congress, including those covering the phase 2 MOUNTAINEER study (NCT03043313)³ and the phase 3 KEYNOTE-811 trial (NCT03615326).⁴ Additionally, she spoke about her work in the phase 2 ECOG-ACRIN trial (NCT04751370) assessing neoadjuvant nivolumab (Opdivo) plus ipilimumab (Yervoy) in patients with microsatellite instability-high or mismatch repair deficient rectal cancer.⁵

“I’m hoping that we see more treatment options for patients [and that] we identify more patient subtypes that we can target and find actionable alterations for,” Ciombor said.
