Effect of Adjunctive Metformin on Recurrence of Non-DM Colorectal Cancer Stage II High-risk/ III Colorectal Cancer
Effect of Adjunctive Metformin on Recurrence of Non-DM Colorectal Cancer Stage II High-risk/ III Colorectal Cancer: Open-label Randomized Controlled
The aim of this study is to identify the effect of adjunctive metformin on recurrence of non-DM Stage II High-risk/ III colorectal cancer. This study is open-label randomized controlled study.
The primary endpoint is to compare the 3-year disease free survival between metformin group and non-metformin group. The secondary endpoint is to compare the 5-year overall survival and disease specific survival between two group, to identify the safety of metformin, and to compare the recurrence rate of polyps after polypectomy between two groups.

Experimental: metformin
|
The patients of this group are treated according to NCCN guideline for stage II high-risk/ III colorectal cancer and receive an additional prescription metformin.
Metformin will be prescribed 1g/day (500mg, 2 table/day, or 1000mg, 1 table/day).
After adjustment period for 1month, patients who do not have side effects will be taken metformin for additional 47 months (total 48months including the adjustment period).
