There have been expectations that neoadjuvant hormonal therapy would decrease the rate of positive surgical margins and, therefore, to improve the patient's survival rate after radical prostatectomy for clinically localized prostate cancer. A review of seven prospective randomized studies for clinically localized prostate cancer revealed a significant decrease in the positive surgical margin rate in cases of clinical T2 disease after neoadjuvant hormonal therapy with prostatectomy. However, this treatment did not alter the rate of seminal vesicle invasion or lymph node metastasis after radical prostatectomy. ⋯ Furthermore, there was no improvement in prostate specific antigen-free survival rate after a maximum of 4 years follow-up. Further research is required to determine the optimal duration of neoadjuvant hormonal therapy and whether this therapy increases the survival rate. Neoadjuvant hormonal therapy before radical prostatectomy is not supported by any outcome at this point and its use remains in the investigational stage.

Review[Management of a hormone dependent cancer with endocrine therapy--prostate cancer].
We offer a historical overview of endocrine therapy for prostate cancer. Hormone therapy remains the cornerstone of treatment for patients with locally advanced or metastatic prostate cancer. ⋯ New treatment strategies and modalities such as LH-RH antagonists, intermittent hormonal therapy, and antiandrogen monotherapy are appearing and being tested in clinical trials. However, to date there is still no effective therapy for patients who have hormone refractory disease.
