Laparoscopic Abdominoperineal Resection after Preoperative Chemoradiotherapy for Adenocarcinoma Associated with Anal Fistula

A 72-year-old man had a chief complaint of anal pain and difficulty in defecation. He was diagnosed with adenocarcinoma by biopsy from a tumor of the anal canal. A computed tomography scan revealed neither regional lymph node metastasis nor distant metastasis. Hence, he was diagnosed with cT3N0M0, c...

Summary:A 72-year-old man had a chief complaint of anal pain and difficulty in defecation. He was diagnosed with adenocarcinoma by biopsy from a tumor of the anal canal. A computed tomography scan revealed neither regional lymph node metastasis nor distant metastasis. Hence, he was diagnosed with cT3N0M0, cStage Ⅱa anal canal cancer. Preoperative capecitabine- based chemoradiotherapy(CRT)(50.4 Gy in 28 fractions of 1.8 Gy each)was implemented. Digital rectal examination and imaging evaluation 8 weeks after preoperative CRT revealed that the tumor had shrunk. Fifteen weeks after preoperative CRT, laparoscopic abdominoperineal resection was performed. The pathological findings showed mucinous adenocarcinoma associated with anal fistula. At present, 12 months after the operation, no local recurrence and distant metastasis has been detected under follow-up evaluations.
