Adjuvant Systemic Chemotherapy for Stage II and III Colon Cancer after Complete Resection: An Updated Practice Guideline

The routine use of adjuvant chemotherapy for all patients with stage II colon cancer is not recommended. However, a subset of patients with high-risk stage II disease should be considered for adjuvant therapy. Patients with completely resected stage III colon cancer should be offered adjuvant chemotherapy. Treatment should depend on factors such as patient suitability and preference, and patients and clinicians must work together to determine the optimal course of treatment.
