Background: Current guidelines recommend selective adjuvant chemotherapy for stage II colon cancer with high-risk features. This study aimed to assess survival benefit of adjuvant chemotherapy in patients with stage II colon adenocarcinomas ≥5 cm without high-risk features.
Methods: The National Cancer Database was retrospectively reviewed (2010-2019) for all patients with pathologic stage II colonic adenocarcinomas ≥5 cm who underwent colectomy.
Background: As the population ages, nonagenarian patients with cancer are more frequently treated. This study aimed to assess the characteristics of colon and rectal cancer in patients aged ≥90 years and to evaluate the role of surgical intervention in this age group.
Methods: This retrospective cohort study included nonagenarian patients with colon and rectal cancer identified from the Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2020.
