Clinical Utility of Including ctDNA Monitoring in Standard-of-Care CRC Surveillance

Thematic Newsreels

Advertisement

Arvind N. Dasari, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses data presented at the ESMO Gastrointestinal Cancers Congress 2025, which showed that adding circulating tumor DNA (ctDNA) testing to current standard of care surveillance for patients with colorectal cancer (CRC) better identified patients who are appropriate candidates for metastasis-directed therapy.

MRD Testing: Recent Data and Ongoing Efforts

Circulating tumor DNA has many roles in cancer treatment: early diagnosis, tumor profiling, determining response to therapy, and tracking clinical dynamics. In this video, Arvind N. Dasari, MD, MS, of The University of Texas MD Anderson Cancer Center, focuses on it as a marker for measurable residual disease (MRD), which can help to determine risk of disease recurrence in patients with cancer. Dr. Dasari reviews the development of assays for MRD, both tumor-informed and tumor-agnostic, and provides top-level data from several clinical trials on the topic that have informed the role of MRD testing in both the colorectal cancer and general solid tumor space.

Erika Hamilton, MD, on Oral SERDs in Breast Cancer: State of the Science

Erika Hamilton, MD, Director, Breast Cancer Research at Sarah Cannon Research Institute, provides a look at “where we stand in 2025” in the field of oral selective estrogen receptor degraders (SERDs) for patients with estrogen receptor–positive, HER2-negative breast cancer. She discusses the first and only FDA-approved oral SERD, elacestrant, indicated for use after CDK4/6 inhibitor therapy in patients with ESR1 mutations; reviews agents still being tested in clinical trials, such as imlunestrant and camizestrant; and highlights the role of oral SERDs as both monotherapies and in novel combinations. As Dr. Hamilton explains, “there haven’t been novel endocrine backbones [for these patients] since fulvestrant.”
