Study information
Scientific title
HYpofractionated irradiation for PROstate cancer: a randomised multicentre phase III study
Acronym
HYPRO
Study hypothesis
The hypofractionated regimen of 19 fractions will result in an increase of relapse-free survival by 10% with the same acute and late toxicity as the standard fractionation of 39 fractions.
Ethics approval

Condition
Prostate cancer
Intervention
Hypofractionation arm:
Total dose of 64.6 Gy in 19 fractions of 3.4 Gy, three times per week, in 7 weeks, using conformal External Beam Radiation Therapy (EBRT).
Reference arm:
78 Gy total dose consisting of 39 fractions of 2 Gy, five times per week, in 8 weeks, using conformal EBRT.

Primary outcome measure
Five-year relapse-free survival after treatment. Relapse is defined as biochemical relapse, clinical relapse, loco-regional or distant relapse or start with hormonal therapy, whichever occurs first. Biochemical relapse will be defined in this study as PSA greater than the current nadir plus 2 mg/l, without backdating.
Other endpoints of this study will be:
1. The acute gastro-intestinal and genito-urinary toxicities by using the RTOG/EORTC Late Radiation Morbidity Scale questionnaire and scoring system.
2. The late gastro-intestinal and genito-urinary toxicities by using the RTOG/EORTC Late Radiation Morbidity Scale questionnaire and scoring system.
Secondary outcome measures
1. Quality of life by using the EORTC-PR25 prostate module
2. Erectile functioning by using the International Index of Erectile Function (IIEF)
