 The prostate if not previously treated will be treated to a dose of 35-40 Gy in 5 fractions. All visible nodal metastases will be treated to a dose of 30-35 Gy in 5 fractions. It is very likely that nodal metastases will shrink significantly often completely with ADT. In this scenario, the involved nodal regions will be treated to a more modest dose of 25 Gy in 5 fractions roughly equivalent to a dose of 46 Gy in 23 fractions assuming an αβ value of 1.4. Non-spine bone metastases will be treated to a dose of 30-40 Gy in 5 fractions. Metastases in the brain, spine, lung, liver, and adrenal will be treated according to established stereotactic radiotherapy SRT policies at Sunnybrook Odette Cancer Centre. Comprehensive SRT should be delivered within 3 months of starting ADT.
