Brief Summary
The purpose of this study is to establish the influence of time-interval between preoperative hyperfractionated radiotherapy (5x5 Gy) and surgery on long term overall survival (5 years), local and distant recurrence rate, downstaging rate, sphincter saving procedures, radical resection rate (R0) in patients with locally advanced rectal cancer operated on according to TME technique. In particular 3D endosonography and 3rd generation ultrasonic contrast agents are evaluated to assess response to radiotherapy.
