However, higher doses have raised the concern of increased normal tissue toxicity, such as gastrointestinal and genitourinary toxicities. This study reports the effect of escalating the radiation dose in intermediate and high risk prostate cancer patients; via image guided intensity modulated radiotherapy; on the acute toxicity profile. The study also estimates the mean of change of prostate position using online verification of intraprostatic fiducial markers ER -
