[Cytopuncture of lymph nodes opacified by lymphography in the pretreatment evaluation of prostatic cancer].

Fine needle aspiration of iliac lymph nodes after lymphography was performed in nineteen patients with prostatic carcinoma, ranging from stage A to C. In four patients (21%), fine needle aspiration showed lymph node dissemination. 3 patients were classified as stage B, and 1 as stage C before aspiration. In this study, fine needle aspiration biopsy proved to be useful in the staging of prostatic carcinoma.
