When you do recommend conventional fractionation over moderate hypofractionation for prostate cancer?

I am routinely using 2.5-3 Gy in patients with low, intermediate, and some high risk patients so I guess I am an early adopter (or a cavalier nutjob). The exclusion criteria from the two published non-inferiority trials of moderate hypofractionation that are relevant to this question are quoted more...

At the Scripps proton therapy center, we have been treating most of our prostate patients using the 70 Gy in 28 fractions with simulteous boost to the DIL (seen on MRI) to 78 Gy using Intensity Modulated Proton Therapy. The on...

I had measured some unexpectedly fortuitous and significant lowering of the IPSS in IPSS>20 patients undergoing 81 Gy/45 fx IG-IMRT (the "old" popular MSKCC regimen). In my experience, 79 of 81 IPSS>20 patients had a stable or (much) lower IPSS after 1.8 Gy daily fractional doses. ( @Dr. First Last....
