This project combines advances in functional imaging of prostate cancer and hypofractionation through stereotactic body radiotherapy (SBRT), with an aim to improve tumour control and reduce or maintain normal tissue complications. The strategy will make use of the combined effectiveness of several functional imaging approaches to identify the dominant lesion(s) within the prostate. An SBRT treatment plan will be designed which utilizes 5 fractions to treat the entire prostate gland with an additional boost to the dominant lesion. The lower dose to the entire prostate should reduce normal tissue complications but still be effective in treating prostate cancer while the increased dose to the dominant lesion should improve tumour control. The use of only 5 fractions will reduce the number of patient visits, thus reducing overall treatment costs.
