Adjuvant Radiotherapy May Fight Advanced Prostate Cancer
TUESDAY, Nov. 14 (HealthDay News) -- A 10-year randomized, prospective clinical trial may provide guidance on the use of adjuvant radiotherapy after radical prostatectomy in men with pathologically advanced prostate cancer.

Radiation Delay Does Not Affect Prostate Cancer Relapse
FRIDAY, Nov. 3 (HealthDay News) -- Delaying radiotherapy for prostate cancer more than 40 days after the initial consultation has no significant effect on biochemical relapse rates, according to study results published in the October issue of the American Journal of Clinical Oncology.
Pelvic Radiation Doesn't Benefit All Prostate Cancer Patients
