title: Preoperative concomitant radiochemotherapy and IORT in locally advanced rectal cancer.
abstract: 34 patients with locally advanced (T4) or recurrent rectal cancer have been treated with: 1. external beam radiotherapy (45-48 Gy) + 5FU(1000 mg/m2/daily iv continuous infusion day 1-4) + MMC (10 mg/m2/daily iv, day 1); 2. surgical resection (if feasible) + IORT (10-15 Gy); 3. adjuvant chemotherapy (5FU+leucovorin, 6-8 cycles). Grade 3 acute hematological toxicity was observed in 1 case only. 23 of 34 patients underwent radical surgery. Perioperative mortality and morbidity was 0% and 17% respectively. In the 23 operated patients with a mean follow-up of 18.6 months there were 2 local recurrences, 5 blood metastases, (1 death of disease). 16 patients were shown to be NED (3-36 months).
