title: Post-lymphangiography fine needle aspiration lymph node biopsy in staging carcinoma of the prostate: preliminary report.
abstract: Five cases of clinical stage B carcinoma of the prostate are reported. Bipedal lymphangiography showed unequivocal involvement of the pelvic nodes in 3 patients and was equivocal in the other 2. Percutaneous transabdominal fine needle aspiration biopsy of abnormal or suspicious iliac nodes was performed and a positive cytolocal diagnosis of metastasis was obtained in all 5 patients. Therefore, staging lymphadenectomy and an extensive radical operation were avoided. Percutaneous fine needle biopsy is a reliable, easy and safe technique that should be used in staging prostatic carcinoma whenever there is evidence of metastatic nodal involvement by lymphangiography.
