Primary Outcome Measures:
  • proportion SDR of patients with no grade III/IV toxicity and/or treatment discontinuation [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
    Proportion SDR of patients with no NCI CTC AE grade 3-4 toxicity and no discontinuation of treatment during the full set of 18 fractions by any reasons in the intent-to-treat (ITT) population


Secondary Outcome Measures:
  • biochemical recurrence free survival (BFS) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Quality of Life [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Quality of Life Scores as measured by the EORTC-QLQ30 and -PR25 questionnaires

  • overall survival [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 80

Estimated Study Completion Date: February 2016
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
prostate bed Radiation: hypofractionated helical IMRT
hypofractionated helical IMRT of the prostate bed, 18 x 3 Gy
prostate bed & lymph nodes Radiation: hypofractionated helical IMRT
helical IMRT of the prostate bed (18 x 3 Gy) and the pelvic lymph nodes (18 x 2.5 Gy)

Detailed Description:

While evidence on safety and efficacy of primary hypofractionated radiotherapy in prostate cancer is accumulating, data on postoperative hypofractionated treatment of the prostate bed and of the pelvic lymph nodes is still scarce. This phase II trial was initiated to investigate safety and feasibility of hypofractionated treatment of the prostate bed alone or with the pelvic lymph nodes.

A total of 80 prostate cancer patients with the indication for adjuvant radiotherapy will be enrolled, where 40 patients with a low risk of lymph node involvement (arm 1) and another 40 patients with a high risk of lymph node involvement (arm 2) will each receive 54 Gy in 18 fractions to the prostate bed. Arm 2 will be given 45 Gy to the pelvic lymph nodes additionally. Helical Tomotherapy and daily image guidance wil be used.
