title: Efficacy of total androgen blockade in metastatic prostatic carcinoma with transient hypogonadotropic hypogonadism: a case report.
abstract: A patient affected by metastatic prostatic carcinoma and hypogonadotropic hypogonadism (HH) was treated with flutamide 750 mg/day plus an LH-RH analog. After confirmation of basal castration during treatment, he continued with antiandrogens alone. Following the normalization of gonadic function and subjective mild bone flare-up, the patient resumed the initial treatment and obtained a partial response. When flutamide was interrupted because of liver toxicity, the patient showed progressive disease in the bone, which was unresponsive to both flutamide resumption and salvage hormone therapy (bicalutamide). The patient is currently receiving chemotherapy with VP16 and estramustine phosphate and is showing both serologic (PSA) and symptomatic response. The interest of this case lies in the incidental detection of HH during therapy and in the responsiveness to treatment.
