Abstract |
A 60s man was diagnosed with rectal cancer and underwent low anterior resection of the rectum. The pathological diagnosis was mucinous adenocarcinoma, pT3(SS), pN0, pM0, pStage Ⅱ. Two years after the primary surgery, contrast-enhanced CT showed local recurrence on the oral side of the anastomosis. As the tumor had invaded the left seminal vesicle and coccygeus muscle, neoadjuvant chemoradiotherapy(NACRT)(S-1 80mg/m / 2 plus 45 Gy/25 Fr)was performed. After NACRT, abdominoperineal resection, including the left seminal vesicle, coccygeus muscle, and coccygeal bone, was performed. Pathological examination showed a histological response of Grade 2 and that R0 resection was achieved. Although the only radical treatment of locally recurrent rectal cancer is R0 resection, we performed R0 resection with Grade 2 histological response to NACRT.
