Percutaneous lymph node aspiration biopsy and tumor grade in staging of prostatic carcinoma

Percutaneous fluoroscopy‐guided fine‐needle aspiration biopsy was performed for staging procedures in 31 patients with clinically localized carcinoma of the prostate and showed overall accuracy of 93.54%, with a false‐negative rate of 6.46%. The Gleason grading system was found to be highly accurate in predicting the absence or presence of nodal metastases in low‐and high‐grade tumors (Gleason's sums 2, 3, or 4, and 8, 9, or 10). The combination of pelvic node biopsy aspiration and tumor grade can result in a very accurate prediction of nodal involvement, and may spare patients a staging lymphadenectomy or even an unnecessary radical operation.
