Abstract

The US T(2b) study of 3 months of neoadjuvant hormonal therapy (NHT) showed a reduction in the likelihood of positive margins from 48% (control group) to 18% in the treated patients. Follow-up at 42 months shows that the cumulative relapse rate (prostate specific antigen) for 129 patients having NHT was not statistically different from that of the 126 control patients. Because the T(2b) study has been criticized for lacking central pathology review, we present a review of a series involving only one surgeon (MS) and one pathologist (FC) of NHT plus prostatectomy (109 patients) v prostatectomy alone (145 patients) with 24 months' follow-up. Positive margins were decreased from 38% in the untreated to 28% in the treated group, the only statistically significant difference in the results. Biochemical recurrence (PSA >0.2 ng/mL) was higher in the treated group, reflecting selection of more aggressive tumors for NHT, but the difference was not statistically significantly. The incidence of extracapsular extension, seminal vesicle invasion, and lymph node metastasis was similar in the two groups. The largest nonrandomized experience with NHT shows a decrease in the incidence of positive surgical margins when used in high-risk patients with clinically localized carcinoma of the prostate. However, it does not have an impact on disease-free survival at a mean 24-month follow-up.
