Summary
Brief summary (as posted)
The goal of this observational study is to determine the optimal surgical strategy based on oncologic outcomes in patients with stage I-III right-sided colon cancer who underwent curative right hemicolectomy. The main question it aims to answer is: Is there a significant difference in 5-year recurrence-free survival (RFS) between patients treated with Complete Mesocolic Excision (CME) and those treated with tumor specific mesocolic excision (TSME)? Participants will include patients who underwent curative right hemicolectomy for right-sided colon cancer between 2015 and 2020 at eight institutions. They will be categorized into two groups based on the surgical technique received-CME group and TSME group-and evaluated for primary and secondary endpoints of 5-year recurrence-free survival (RFS) and overall survival (OS), respectively.
