Many patients with localized prostate cancer choose radiotherapy for treatment. Recent improvements in technology have lead to better outcomes with less side effects and better disease control rates by allowing high doses of radiation to be delivered to the cancer with lower doses to surrounding healthy tissues. Currently patients are required to attend daily treatments over seven to eight weeks which can be costly and disruptive for patients, especially those not living close to a cancer centre.

There is recent research that suggests that the same or better outcomes might be achieved in prostate cancer by delivering a smaller number of treatments, but with a higher dose of radiation given on each visit, over a shorter time than the usual seven to eight weeks.

In this study the investigators propose to treat patients with prostate cancer using 16 treatments over four weeks, thus reducing the number of visits to the cancer centre for treatment by 50%.
