Abstract
- This study analyzed the oncological outcomes of robotic-assisted total mesorectal excision (TME) in patients with rectal cancer after neoadjuvant concurrent chemoradiotherapy (CCRT). We enrolled 109 consecutive patients with stage II–III rectal cancer who underwent robotic-assisted TME after neoadjuvant CCRT at one hospital between July 2013 and June 2018. All 109 patients underwent preoperative CCRT. Of them, 37 (33.9%) achieved a pathologic complete response, and 29 (26.6%) experienced relapse, with local recurrence in 9 (8.3%) and distant metastasis in 20 (18.3%). R0 resection was performed in 104 (95.7%) patients; however, 7 (6.7%) of them developed local recurrence and 17 (16.3%) developed distant metastasis. Over a median follow-up of 42 months, the 3-year disease-free survival and overall survival rates were 73.4% and 87.2%, respectively. Robotic-assisted TME after neoadjuvant CCRT is safe and effective for treating patients with stage II–III rectal cancer in one institution with acceptable short-term oncological outcomes. It may be a therapeutic alternative to salvage surgery for T4 tumors invading adjacent organs, such as the bladder, prostate, and uterus. [ABSTRACT FROM AUTHOR]
