[Complete androgenic blockade: myth or reality. Study and follow-up of 35 patients with advanced carcinoma of the prostate]. / Bloqueo androgénico completo: mito o realidad. Estudio y seguimiento de 35 pacientes con carcinoma de próstata avanzado.

Retrospective evaluation of the efficacy of complete androgenic blockade started by Labrie et al. using therapy with leuprolide acetate in monthly dosage of 7.5 mg i.m. associated to flutamide at the usual dosage in 35 patients with prostate adenocarcinoma in C-D1-D2 stages, who had not been given prior anti-neoplastic therapy. Clinical and analytical control studies were carried out during therapy follow-up for a maximum time of 36 months. The objective response of adverse events that can be superimposed to previous studies carried out with analogs on daily administration was assessed. Castration levels achieved were maintained for the length of the study below 50 ng/dl. Correlation between tissue type, rated according to the Mostofi classification, evolution or degree of response obtained and preserved increase of tumour markers (PSA, PAP, LDH, Prolactin) was evaluated; the evolution observed in patients who maintained high values of markers was worse with the referred treatment.
