Radoslaw Pach, Jagiellonian University
  Purpose
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.

Condition Intervention Phase

Primary Purpose: Treatment
Official Title: Randomized Clinical Trial on Preoperative Radiotherapy 25 Gy in Rectal Cancer

Further study details as provided by Radoslaw Pach, Jagiellonian University:

Primary Outcome Measures:
  • local and systemic recurrence rate [ Time Frame: 5 years ]
    Rate of local and sytemic recurrences in patients included to the protocol.


Secondary Outcome Measures:
  • radical resections rate (R0) [ Time Frame: 1 month ]
    Rate of R0, R1 and R2 procedures according to Hermanek.

  • sphincter saving (sparing) procedures [ Time Frame: 1 month ]
    Rate of sphincter saving operations in both arms.

  • overall survival [ Time Frame: 5 years ]
    Overall survival and disease specific survival at 5 years follow-up

  • downstaging of rectal cancer [ Time Frame: 1 month ]
    Downstaging of the rectal cancer after preoprearite radiotherapy - assessed by comparison of preoperative ERUS, 3D ERUS, contrast enhanced ERUS and postoperative histologic staging

Detailed Description:
The treatment group comprises patients with locally advanced rectal cancer who were operated on in the 1st Department of General Surgery, Jagiellonian University, Cracow. The data on survival has been systematically collected using national census registry. Patients are qualified to preoperative radiotherapy 5x5 Gy and then randomly assigned to subgroups with different time interval between radiotherapy and surgery: one subgroup consists of patients operated on 7-10 days after the end of irradiation, the second subgroup consists of patients operated on after 4-5 weeks. Both should be homogenous in sex, age, cancer stage and localization, distal and circumferential resection margins, number of resected lymph nodes. 3D endorectal ultrasound and endorectal ultrasound with SonoVue are performed to assess the tumor before and after preoperative radiotherapy.
