Prostate Cancer, Proton Radiation
Brief summary
The purpose of this study is to see what effects, good and/or bad, proton based radiation combined with low dose chemotherapy and hormonal therapy, has on patients and their cancer.
Interventions
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.
Total of 45 Gy over 25 treatments to prostate + SV + LN, then proton boost total of 32.4-36 CGE over 18-20 treatments to prostate + SV. Low dose docetaxel every week during RT followed by androgen deprivation therapy for 6 months.

Eligibility
Inclusion criteria
\* Adenocarcinoma of the prostate.
Exclusion criteria
* Previous prostate cancer treatment such as chemotherapy and/or pelvic radiation. * Active inflammatory bowel disease (diverticulitis, Crohn's disease or ulcerative colitis) affecting the rectum. (Non-active diverticulitis and Crohn's disease not affecting the rectum are allowed.) * History of hip replacement. * Prior intrapelvic surgery. This includes the following: * Transrectal or rectal surgery other than polypectomy or hemorrhoid removal or banding * Transabdominal pelvic surgery * Bladder surgery * Prior myocardial infarction (MI) or congestive heart failure (CHF). * Taking Saw Palmetto or methotrexate and unable or unwilling to discontinue its use during radiation.
