Brief Summary
The purpose of this study is to determine whether adjuvant radiotherapy following radical prostatectomy in prostate cancer patients with positive margins or capsular penetration improves biochemical, overall and/or cancer specific survival and whether adjuvant radiotherapy is reasonably well tolerated when compared to watchful waiting.

Eligibility Criteria
You may qualify if:
- Patients with pT3aN0M0 or pT2N0M0 prostate cancer with a positive margin, gleason score 2-10, preoperative PSA \< 20 ug/l, postoperative PSA \<0.5 ug/l after surgery (within 8 weeks), the WHO performance status 0-2, life expectancy at least 3 months, informed consent obtained.
You may not qualify if:
- Other simultaneous cancer therapy including systemic endocrine therapy; more than 12 weeks has elapsed since surgery for prostate cancer; metastatic disease (N+ or M1); cancer invasion to the seminal vesicles; any other previous malignancy within the last 5 years except basalioma or squamous cell carcinoma of the skin; any contraindication to irradiation (severe locoregional infection, prior radiation therapy to the prostate/bladder); any physical or mental condition, which in the opinion of the investigator, may interfere with patient's ability to comply with scheduled visits.
