Dewayne,
I spent a whole afternoon at a university medical library researching various studies on HDR mono-therapy before making my decision. I found that HDR mono-therapy is becoming more accepted for low and intermediate risk patients. In Europe and Japan, they are also treating high risk patients with mono-therapy with good results.
Some relevant studies:
www.ncbi.nlm.nih.gov/pmc/articles/PMC4003433/jrr.oxfordjournals.org/content/early/2013/03/29/jrr.rrt027.fullwww.brachyjournal.com/article/S1538-4721(14)00505-4/fulltextMy R.O. explained that the only potential benefit of adding in a course of EBRT is to treat the pelvic lymph nodes, but there is a controversy now about
whether the EBRT to pelvic lymph nodes actually does any good or not.

Hormones before HDR brachy is also controversial. With LDR brachy, hormones are sometimes used to shrink the prostate before seed implant. With HDR, some R.O.s claim that shrinking a large prostate is not necessary before treatment, and some studies have claimed that adding the hormone treatment does not improve observed results.
As with any type of treatment, selecting a competent practitioner is extremely important. As one study concludes: "However, to date there are only a small number of centers worldwide that carry out HDR monotherapy. Because HDR monotherapy does not include supplemental EBRT, it requires technical maturity in terms of both implant technique and treatment planning. A special patient care protocol is also needed to manage the single implant over several days of treatment."
