Neoadjuvant Hormone and Radiation Therapy Followed by Radical Prostatectomy in Patients With High-Risk Prostate Cancer
Neoadjuvant Hormone and Radiation Therapy Followed by Radical Prostatectomy in Patients With High-Risk Locally Advanced Prostate Cancer and Biomarker Research
National Taiwan University Hospital

INTERVENTIONAL
Conditions
Summary
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Androgens can stimulate the growth of prostate cancer cells. Hormone therapy can fight prostate cancer by androgen deprivation. It is not yet known if neoadjuvant radiation therapy is a more effective therapy for high-risk prostate cancer. PURPOSE: Two-stage randomized trial to compare the effectiveness and safety of neoadjuvant radiotherapy and hormone therapy followed by radical prostatectomy in men with high-risk locally advanced prostate cancer
