[A case of advanced rectal cancer responding to oral UFT and Leucovorin-based preoperative chemoradiation therapy].

We report a case of a 44-year-old male with advanced lower rectal cancer that showed a significant effect after preoperative chemoradiation therapy. Preoperative radiation and chemotherapy included whole pelvis irradiation (30 Gy in total), oral UFT (500 mg/day), and Leucovorin (75 mg/day) was administered daily for 4 weeks. Consequently, the patient underwent a total pelvic exenteration with lymph node dissection (D 3).
