Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Randomized trial comparing 2 external beam radiotherapy fractionation schemes in patients with localized high risk prostate cancer. Primary endpoint is acute toxicity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients enrolled onto this study will be randomized to one of the following treatment arms:

* Standard fractionation: Using 2 sequential IMRT plans, the pelvic lymph nodes and prostate will initially be treated to 46 Gy in 23 fractions, followed by a subsequent boost to the prostate to a total dose of 78 Gy.
* Hypofractionation: Using a one phase IMRT plan, the pelvic lymph nodes will be treated to a dose of 48 Gy in 25 fractions, while the prostate will be treated to a dose of 68 Gy in 25 fractions concomitantly (simulataneous integrated boost).

In addition, all patients receive 1.5- 3 years of androgen deprivation therapy.
