[Cytopuncture: an alternative to pelviscopy in the diagnosis of lymphatic metastases of urologic pelvic tumors].
119 patients with prostatic or vesical tumours without metastases were studied by lymphography-aspiration cytology to detect lymph node metastases. 12% of aspiration cytologies were uninterpretable, corresponding to N-patients. 12% of the 105 interpretable cases were positive. Some of the patients with negative biopsies were treated nonsurgically. 28 bladder tumours were treated intravesically. 11 prostatic cancers were treated by radiotherapy and 63 patients underwent surgical resection. These 63 patients had an interpretable aspiration cytology and surgical control. Aspiration cytology was falsely negative in 7 cases: 4 microscopic metastases and 3 macroscopic metastases. The sensitivity of aspiration cytology after lymphography is 66% and its specificity is 100%. The positive predictive value is 100% and the negative predictive value is 92.3%. These 7 false-negative results included 3 macroscopic metastases already identified on CT scan and 4 micrometastases in which surgical resection was legitimate.
