Intensive follow-up after colorectal cancer surgery improves survival. A risk-adapted approach using imaging and tumor markers is most effective and cost-efficient for detecting recurrence.
Area of Science:
- Oncology
- Surgical Oncology
- Gastroenterology
Background:
- Colorectal cancer (CRC) recurrence is a significant concern after curative resection.
- Postoperative surveillance aims to detect recurrence early for improved patient outcomes.
- Current evidence suggests intensive follow-up strategies may enhance survival benefits.
Purpose of the Study:
- To evaluate the impact of intensive follow-up regimens on survival after curative CRC resection.
- To identify the most beneficial surveillance methods, including imaging and biomarker testing.
- To assess the efficacy and cost-effectiveness of risk-adapted follow-up strategies.
Main Methods:
- Review of recent evidence on postoperative surveillance for colorectal cancer.
- Analysis of regimens incorporating cross-sectional imaging and carcinoembryonic antigen (CEA) determination.
- Evaluation of risk-adapted approaches focusing on high-risk patient populations.
Main Results:
- Intensive follow-up is associated with a small but significant improvement in survival.
- Regimens combining cross-sectional imaging and CEA monitoring offer the greatest benefit.
- Risk-adapted surveillance enhances both efficacy and cost-effectiveness.
Conclusions:
- Intensive postoperative surveillance, particularly risk-adapted strategies using imaging and CEA, improves survival after CRC resection.
- Further large randomized controlled trials are necessary to establish optimal surveillance protocols.
- Future trials should comprehensively analyze survival, quality of life, and cost-effectiveness.
