Percutaneous pelvic lymph node aspiration in carcinoma of the prostate.

We report on 121 patients with adenocarcinoma of the prostate who underwent lymphangiography and, when indicated, subsequent fine needle aspiration biopsy of lymph nodes. The clinical staging correlation with this procedure reveals an assumed falsely negative rate of 5 to 15 per cent. The falsely positive rate is 0. This procedure is essentially without morbidity and has allowed us to stage more confidently prostatic cancer and make appropriate therapeutic recommendations.
