RATIONALE: Radiation therapy uses high energy x-rays to damage tumor cells.
PURPOSE: Randomized phase III trial to compare the effectiveness of conventional radiation therapy with high-dose radiation therapy in treating men with stage I or stage II prostate cancer.

Official Title: | A PHASE III TRIAL EMPLOYING CONFORMAL PHOTONS WITH PROTON BOOST IN EARLY STAGE PROSTATE CANCER: CONVENTIONAL DOSE COMPARED TO HIGH DOSE IRRADIATION |
Estimated Enrollment: | 390 |
Study Start Date: | January 1996 |
OBJECTIVES: I. Determine whether high-dose radiotherapy using conformal photons with a proton boost produces a 20% increase in the proportion of Stage I/II prostate cancer free from local failure and biochemical relapse at 5 years when compared to results of conventional-dose radiotherapy. II. Determine whether high-dose radiotherapy produces a 33% reduction in the cumulative incidence of a rising PSA (second hormone failure) following hormone therapy given at the time of first PSA/clinical failure when compared with conventional-dose radiotherapy. IV.
Assess the relative rectal, bladder, and sexual morbidity of conformal photon doses of 70.2 and 79.2 Gy in these patients. V. Collect, in a prospective manner, paraffin biopsy blocks for subsequent analysis of emerging molecular pathologic predictors of outcome in three patients.
OUTLINE: Randomized study. Arm I: Radiotherapy. Boost to the prostate using high-LET protons followed by irradiation of the prostate, periprostatic tissues, and seminal vesicles using conformal photons with energies greater than 6 MV. Conventional dose. Arm II: Radiotherapy. As in Arm I. High dose.
PROJECTED ACCRUAL: There will be 390 patients accrued into this study over 3 years. An additional 3.5 years will be required for follow-up.
