Reid M. Ness, MD, MPH, on Colorectal Cancer: Updates in Screening Recommendations

Reid M. Ness, MD, MPH, of Vanderbilt-Ingram Cancer Center, discusses significant updates to the NCCN Clinical Practice Guidelines in Oncology for colorectal cancer screening: lowering the age from 50 to 45 for the initiation of average-risk screening for all combinations of race, ethnicity, and sex; and extending the surveillance interval from 5 to 7–10 years following the identification of one to two low-risk adenomas.

Tumor Budding May Provide Independent Prognostic Value for Disease-Free and Overall Survival in Patients With Stage III Colon Cancer

Tumor budding is an emerging prognostic biomarker in colon cancer and currently influences decision-making in patients with pT1 and stage II colon cancer. In stage III colon cancer, its prognostic impact has been limited to small and retrospective cohorts. In a post hoc analysis of the IDEA-France...

None of the patients required chemoradiation or surgery, thus avoiding their attendant morbidities, and so PD-1 blockade may represent a new treatment paradigm. Follow-up on the durability of response is needed (Abstract 16).
