Protocol Title: Postoperative or Salvage Radiotherapy (RT) for Node Negative Prostate Cancer Following Radical Prostatectomy
Principal Investigator: Henderson, Randal
Objective: The purpose of this study is to see what effects, good and/or bad, proton radiation, and/or conventional radiation and hormonal therapy (if applicable), has on prostate cancer that has already returned or the risk of prostate cancer returning.
Description: This study aims to examine the treatment-related rate of acute grade 3 gastrointestinal and genitourinary toxicity following treatment with proton based radiation therapy.
Phase: Phase II (Cancer Control)
Age Group: Adult
Age: 18 Years - N/A
Treatment: POSTOP NON-HIGH RISK: 66.6 CGE to prostate bed POSTOP HIGH RISK: 45 Gy to whole pelvis followed by 21.6 CGE to prostate bed and hormonal therapy encouraged SALVAGE HIGH RISK: 45 Gy to whole pelvis followed by 25.2 CGE to prostate bed, if image indicated an additional 3.6 CGE and hormonal therapy encouraged
Detailed Eligibility: INCLUSION CRITERIA: 1. Ages 18 years-old and older. 2. Prostate cancer treated primarily with open, laparoscopic or robotically assisted prostatectomy. 3. Maximum PSA value of 20 ng/ml. EXCLUSION CRITERIA: 1. Evidence of distant metastasis (M1). 2. Prior systemic chemotherapy for any reason. 3. Previous irradiation to the pelvis that would compromise the ability to deliver the prescribed study treatment. 4. Active inflammatory bowel disease (Crohn's disease, diverticulitis or ulcerative colitis) affecting the rectum. (Non-active diverticulitis and Crohn's disease not affecting the rectum are allowed). 5. History of hip replacement. 6. Prior or concurrent cancer, other than non-melanomatous skin cancer, unless disease free for at least 5 years. 7. Taking Saw Palmetto or methotrexate and unable or unwilling to discontinue its use during radiation.
