Real-world Retrospective Data Analysis of Adjuvant Therapy for Patients With Stage II-III Colon Cancer After Radical Surgery

Study Overview
=================
Brief Summary
-----------------
Background: . The incidence and mortality of colon cancer are high in China and in the world. . The treatment of many patients in the real world is not standardized, and there are problems such as over-treatment or under-treatment. To explore the adjuvant treatment of colon cancer in the Chinese population, this study will retrospectively analyze real-world data on adjuvant therapy for colon cancer in Chinese patients after radical surgery. The purpose of research: . Current status of adjuvant therapy for stage II-III colon cancer in the real world: chemotherapy regimen, chemotherapy time, efficacy, safety, etc. . Comparison of efficacy and safety of different adjuvant chemotherapy time (<3 months vs. >=3 months) in high-risk stage II and III colon cancer patients in the real world . Comparison of efficacy and safety of different adjuvant chemotherapy regimens (XELOX vs. FOLFOX) in high-risk stage II and III colon cancer patients in the real world
