RESUMO
OBJECTIVES: To determine the usefulness of preoperative hormone therapy in patients with organ-confined prostatic carcinoma undergoing radical prostatectomy. METHODS: 7 patients with localized prostatic carcinoma are presented. All patients were submitted to radical prostatectomy; 4 had been randomly selected for preoperative hormone therapy. RESULTS: Histological examination showed no nodal involvement in all cases. The tumor could not be identified (Po) in two of the four patients who received hormone therapy. The other two patients were staged down; the Gleason score remained unchanged in one and increased in the other. The patients who did not receive preoperative hormone therapy showed concordant clinical and pathological stages, except one in whom infiltration of the prostatic capsule was observed. No difference was found concerning the facility in performing surgery between the treated and untreated patients. CONCLUSIONS: Hormonal deprivation eliminated the tumor burden in two cases that might have been completely hormone sensitive, with no correlation in the pretreatment histological grade. Clinical downstaging is achieved by this treatment modality. However, further studies in larger series comparing the percentages of downstaging, histological downgrading, absence of tumor cells in the surgical specimen and impact on survivorship are warranted.
