This is a phase II trial looking at the feasibility of HistoScanning- based dose-painting image- guided interstitial brachytherapy in non- metastatic prostate cancer


Primary endpoint Evaluation of the feasibility of HistoScanning- based dose-painting image- guided interstitial brachytherapy

Secondary endpoints

  1. Evaluating tumor response using HistoScanning
  2. Evaluating locoregional recurrence rates by measuring PSA
  3. Analysis of the correlation between tumor response as determined by HistoScanning and PSA response
  4. Evaluating the safety dose-painting image- guided interstitial brachytherapy by recording serious adverse events

Study Start Date: September 2011
Estimated Study Completion Date: September 2016
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Brachytherapy Radiation: brachytherapy
interstitial image- guided PDR/HDR brachytherapy

Detailed Description:


The study is designed as a prospective monocentric phase II trial. The choice of the therapeutic concept is governed by the risk group that the patient falls into. Risk groups are defined according to the classification by D' Amico.

The following concepts will be used:

HDR brachytherapy: 19,0- 38 Gy / 2-4 fractions (2-4 x 9,5 Gy)

PDR brachytherapy: 35-70 Gy / 50 --100 pulses(1 puls/h, 24 h/d)

Dose painting the timorous areas as seen in HistoScanning as covered with a dose Dref2>130-150%

External beam radiotherapy will be used in addition to brachytherapy for intermediate and high risk patients. The following concepts will be used 50,40 Gy / 28 fractions at 1.8 Gy
