PURPOSE: To estimate the α/β ratio for rectal cancer according to the outcome of three
fractionation schedules of preoperative radiotherapy. METHODS AND MATERIALS:
Between 1996 and 2002, 168 patients with locally advanced rectal cancer were treated as
follows: 53 patients received 25 Gy in 5 Gy per fraction, 45 received 30 Gy in 3.0 Gy per
fraction, and 70 were treated with accelerated hyperfractionation (42 Gy, 1.5 Gy per fraction,
given twice daily). No patients received concurrent chemotherapy. The clinical …
