We report a case of advanced rectal cancer successfully treated with a combination of S-1 and CPT-11 as neoadjuvant chemotherapy. The patient, a 61-year-old man, had a rectal cancer with pelvic viscera invasion and severe stenosis. After colostomy for removing stenosis, he was treated with a combination of S-1 and CPT-11 (S-1 120 mg/body day on day 1-14, CPT-11 120 mg/body/day on day 1 and day 15, every 4 weeks).
