Abstract Background Prostate radiotherapy RT dose escalation has been reported to result in improved biochemical control at the cost of greater late toxicity. We report on the application of Gy in 42 fractions of prostate image guided RT IGRT . The primary objective was to assess 5-year biochemical control and potential prognostic factors by the Phoenix definition. Secondary endpoints included acute and late toxicity by the Radiotherapy Oncology Group RTOG scoring .
