|Condition or disease||Intervention/treatment||Phase|
|Prostate Cancer||Procedure: low-LET photon therapy||Phase 3|
I. Compare disease-free survival rates of patients randomly assigned to adjuvant external-beam radiotherapy vs. no adjuvant therapy following radical prostatectomy and pelvic lymphadenectomy for surgical Stage C (T3 N0 M0) adenocarcinoma of the prostate.
II. Determine the qualitative and quantitative toxicities associated with this adjuvant therapy.
OUTLINE: Randomized study. Randomization takes place when the patient is physically able to begin treatment, any time within 16 weeks after surgery.
Arm I: Radiotherapy. Irradiation of the prostatic bed using megavoltage equipment with effective photon energies of greater than 4 MV.
Arm II: No further treatment.
