Brief Summary
According to the current opinion, local excision in rectal cancer should be limited to selected T1N0 tumours. The investigators addressed the question whether preoperative radio(chemo)therapy can expand the use of this procedure for more advanced cancers. The rationale of preoperative radiotherapy is eradication of mesorectal subclinical disease. Besides, there is a correlation between radiosensitivity of rectal cancers and low cancer aggressiveness. For this reason, conversion to abdominal surgery is needed in patients with radioresistant tumour. The investigators aim to compare the short-course radiotherapy schedule with the chemoradiation in order to determine an optimal scheme. The study hypothesis is that the chemoradiation assures 25% more patients who do not require conversion to an open surgery. In addition, the aim is to asses safety and efficiency of preoperative radiotherapy and local excision for radiosensitive rectal cancer.

Study Arms (2)
1
EXPERIMENTALPreoperative radiotherapy with five fractions of 5 Gy during one week and boost 4 Gy after 1 week interval, total dose 29 Gy; after 6 weeks full-thickness local excision
2
ACTIVE COMPARATORRadiochemotherapy with 28 fractions of 1,8 Gy plus boost 5,4 Gy in 3 fractions \+ simultaneous bolus 5-Fluorouracil and leucovorin; after 6 weeks full-thickness local excision
Interventions
28 x 1,8Gy plus boost 3 x 1,8 Gy with three 2-days cycles of chemotherapy during weeks 1, 3 and 5 of irradiation (the each cycle consisted of leukovorin 20 mg/m2 per day and 10-20 minutes later of 5-fluorouracil 400 mg/m2 per day, both administrated as rapid intravenous infusion)
