PSA-recurrence prostate carcinoma is associated with two general problems.
- Localisation of PSA-recurrence is unconfident. In many cases it's not clear if a local, locoregional oder systemic relapse is available.
- There is no standard therapy proved by randomised clinical trials. Recommended radiotherapy starting with PSA-value < 0.5 ng/ml according to german S3 guidelines is based on retrospective data.
These difficulties may lead to a therapy potentially not adapted to patients situation of disease.This study aims to randomised examine if an instant radiotherapy of prostate PSA-recurrence (PSA-value between 0.2 - 0.99 ng/ml) or a delayed radiotherapy with additional imaging (PSA value >= 1 ng/ml) including PET/CT and bone scintigraphy for reliable information about tumor location and expansion is beneficial regarding therapy efficiency, quality of life and social economic aspects.

PET/CT and Radiotherapy after achievement of PSA marginal value Additive imaging
Radiation: Radiotherapy after achievement of PSA marginal value
Radiotherapy after achievement of PSA marginal value
Active Comparator: instant radiotherapy
Instant Radiotherapy according to guidelines
Radiation: Instant Radiotherapy according to guidelines

- Disease-free survival according to PSA-value [ Time Frame: at the end of follow-up period of 4 years ]Subjects in the control arm have an aftertreatment period of 5 years. Follow-up period of intervention arm ends after 3 to 5 years after radiotherapy. Duration depends on the surveillance period until marginal value is reached. This period is subtracted from maximum follow-up period of 5 years.
- frequency of PSA-persistence [ Time Frame: at the end of therapy , an expected average of 6 weeks ]
- frequency of changes in therapeutic strategies by additional diagnostics [ Time Frame: at the end of therapy , an expected average of 6 weeks ]
- analysis for radiation parameters, restricted to patients of initiating center [ Time Frame: at the end of therapy , an expected average of 6 weeks ]
- therapy and following costs for patients [ Time Frame: time frame of 2 weeks before therapy starts; at the end of therapy , an expected average of 6 weeks; during follow-up each 3 months for the first 2 years, then each 6 months for the rest of follow-up period, an expected average of 2 further years ]
- overall survival [ Time Frame: at the end of therapy , an expected average of 6 weeks ]
- quality of life and side effects [ Time Frame: time frame of 2 weeks before therapy starts; at the end of therapy , an expected average of 6 weeks; during follow-up each 3 months for the first 2 years, then each 6 months for the rest of follow-up period, an expected average of 2 further years ]
