Abstract

Aims: To assess the lymph node content of anterior prostatic fat (APF) sent routinely at robot-assisted laparoscopic radical prostatectomy (RALP) and the incidence of positive nodes in the extended pelvic lymph node dissection. Methods: Between September 2008 and April 2012, APF excised from 282 patients who underwent RALP was sent for pathological analysis. This tissue was completely embedded and lymph nodes counted. Results: In total, 49/282 (17%) patients had lymph nodes in the APF, median lymph node yield in this tissue was 1 (range 1-5). In four patients, the lymph nodes contained metastatic deposits. These patients did not have positive nodes elsewhere in the extended lymph node dissection. Conclusions: APF contains lymph nodes in 1 in 6 patients and infrequently these may be malignant. APF should always be removed at radical prostatectomy. APF should be routinely sent for pathological analysis.
