Key Points

• To evaluate the survival benefits of adjuvant chemotherapy in older patients with varying risk levels of colon cancer.
• Multi-institutional retrospective analysis
• Comparison of outcomes based on cancer stage and risk levels
• Assessment of adjuvant chemotherapy impact on survival
• Significant survival benefits in older patients with high-risk stage III colon cancer
• No survival benefits for high-risk stage II or low-risk stage III cancer
• Emphasis on risk stratification rather than age for treatment decisions
