Condition

Rectal cancer

Intervention

After informed consent had been received patients were randomized at the Finnish Cancer Registry. The randomization process was a true one, no blocks were used. The randomization was done between surgery only and 5x5Gy radiotherapy followed by surgery in one week or less. Radiotherapy was given from 3-4 fields on 5 consecutive days.

Postoperative chemotherapy consisted of bolus 5-fluorouracil (5-FU) treatment in the beginning of the study and intravenous infusion towards the end of the study. Chemotherapy consisted of six cycles and was begun 4-6 weeks after surgery.
All patients were followed up at least five years after surgery.

Radiotherapy: 25 gy (5x5Gy), 4 fields, 5 cm craniocaudal margins, 3 cm anteroposterior and lateral margins. Time interval between radiotherapy and surgery not more than 7 days.

Surgery:Total mesorectal excision with mobilisation of splenic flexure. Choice between anterior resection or abdominoperineal excision in low tumours made at the operation. Diversion recommended.

Chemotherapy: 3-10 weeks after surgery at 350mg/m2 5-FU intravenous bolus on 5 consecutive days+ 20mg/m2 leucovorin immeadiately before 5-FU. Six cycles, interval 3-4 weeks.
