Short-term hormone therapy plus radiation therapy increases survival for men with early-stage prostate cancer

A new study published in the New England Journal of Medicine found that combining short-term hormone therapy (ADT) with radiation therapy significantly improves overall survival rates for men with intermediate-risk prostate cancer. The treatment also resulted in a 10% reduction in disease-specific deaths among high-risk patients.
