HR-A
\< 15% risk of + lymph nodes (LN) \< 15% risk of + LN: Total of 54 Cobalt gray equivalent (CGE) over 30 treatments to prostate + seminal vesicles (SV), then proton boost total of 23.4-27 CGE over 13-15 treatments to prostate +/- SV. Low dose docetaxel every week during radiation therapy (RT) followed by androgen deprivation therapy for 6 months.
