Clinical Studies

A Phase III Prospective Randomized Trial of Standard-Fractionation versus Hypo-Fractionation with Proton Radiation Therapy for Low Risk Adenocarcinoma of the Prostate Rochester, Minn.
The purpose of this study is to compare the effects (good and bad) on patients with prostate cancer by comparing the standard dose of radiation therapy (44 treatments over 8½-9 weeks) with a higher daily dose of radiation (5 treatments over 1-2 weeks) to see if the effects of the treatments are similar or better.

A Phase III Prospective Randomized Trial of Dose-Escalated Radiotherapy With or Without Short-Term Androgen Deprivation Therapy for Patients With Intermediate-Risk Prostate Cancer Rochester, Minn.
RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Androgens can cause the growth of prostate cancer cells. Androgen-deprivation therapy may lessen the amount of androgens made by the body. It is not yet known whether radiation therapy is more effective with or without androgen-deprivation therapy in treating patients with prostate cancer.

PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with androgen-deprivation therapy in treating patients with prostate cancer.
A Phase III Prospective Randomized Trial of Standard-Fractionation versus Hypo-Fractionation with Proton Radiation Therapy for Low Risk Adenocarcinoma of the Prostate Scottsdale/Phoenix, Ariz.
The purpose of this study is to compare the effects (good and bad) on patients with prostate cancer by comparing the standard dose of radiation therapy (44 treatments over 8½-9 weeks) with a higher daily dose of radiation (5 treatments over 1-2 weeks) to see if the effects of the treatments are similar or better.
