Accurate staging of prostatic carcinoma requires determination of the status of the regional draining lymph nodes. Pelvic lymphadenectomy is the definitive examination but has certain morbidity and even mortality. Lymphography is safe but may not be sufficiently accurate. A total of 41 patients with clinically localized disease and abnormal or suspicious lymphograms underwent percutaneous lymph node biopsy. Ten of 11 patients (91 per cent) with abnormal lymphograms and 14 of 30 (47 per cent) with suspicious lymphograms had positive cytology studies. Of the suspicious defects an unopacified void in a nodal chain most frequently was positive. Of 22 potentially curable patients with stages A and B1 disease 12 had metastatic disease.
前列腺癌的准确分期需要确定区域引流淋巴结的状况。盆腔淋巴结清扫术是确定性检查，但有一定的发病率甚至死亡率。淋巴管造影术安全但可能不够准确。共有41例临床局限性疾病且淋巴管造影异常或可疑的患者接受了经皮淋巴结活检。11例淋巴管造影异常的患者中有10例（91%）以及30例可疑淋巴管造影的患者中有14例（47%）细胞学检查呈阳性。在可疑缺损中，淋巴结链中未显影的空洞最常呈阳性。在22例A期和B1期可能治愈的患者中，有12例有转移性疾病。
