Design outcomes

Primary

Measure	Time frame
Does the additional irradiation of the lymphatic drainage area of the prostate improve oncological outcomes in terms of a lower or at least comparable biochemical recurrence rate compared to patients who received irradiation of the prostate bed only?	—

Secondary

Measure	Time frame
Is the additional irradiation of the lymphatic drainage area of the prostate associated with increased toxicity in terms of a higher complication rate or greater severity of complications, either acutely or in the long term, compared to local irradiation alone?	—
