title: Follow-up recommendations for colon cancer.
abstract: Recent evidence suggests that intensive follow-up after curative resection of colorectal cancer is associated with a small but significant improvement in survival. Regimens that employ cross-sectional imaging and carcinoembryonic antigen determination appear to have the greatest benefit. A risk-adapted approach to follow-up, intensively following patients at highest risk of recurrence, increases efficacy and cost-effectiveness. Ongoing improvements in risk stratification, disease detection, and treatment will increase the benefits of postoperative surveillance. Large randomized controlled trials are needed to determine the optimal surveillance regimen and must include an analysis of survival, quality of life, and cost-effectiveness to assess efficacy properly.
