PURPOSE: Percent of @entity189 and @entity3 in the @entity5 are risk factors for occult retroperitoneal @entity3 . High risk @entity1 with clinical stage I and IIA @entity10711 who underwent primary retroperitoneal lymph node dissection were identified to discern any other risk factors for @entity3 . MATERIALS AND METHODS: @entity1 who had undergone retroperitoneal lymph node dissection at our institution from 1993 to 2009 were identified and clinical charts were reviewed. A total of 90 @entity1 with orchiectomy specimens containing more than 30% @entity189 who underwent primary retroperitoneal lymph node dissection were identified and perioperative data were obtained. RESULTS: Of 353 @entity1 90 (25%) had greater than 30% @entity189 and underwent primary retroperitoneal lymph node dissection. Of these @entity1 45 (50%) had @entity3 . Median followup was 1.1 years. Positive lymph nodes identified at retroperitoneal lymph node dissection were noted in 30 (46%) and 15 (60%) @entity1 with clinical stage I vs clinical @entity34 . On multivariate analysis @entity189 (OR 1.02, 95% CI 1.00-1.04) and @entity3 (OR 3.52, 95% CI 1.43-8.67) were associated with positive lymph nodes at retroperitoneal lymph node dissection. The positive predictive value for 100% @entity189 was 65.5%, although the negative predictive value for 30% @entity189 was 85.7%. CONCLUSIONS: @entity189 and @entity3 were significantly and independently associated with the risk of occult retroperitoneal @entity3 . These results should be considered when counseling @entity1 about appropriate treatment options.
