Introduction: Postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) and metastasectomy play an important role in the management of advanced-stage nonseminomatous germ cell tumors (NSGCT). We aimed to analyze preoperative parameters that could predict postoperative histology. Materials and Methods: We analyzed the data of 72 patients who underwent PC-RPLND and 14 patients who underwent metastasectomy after receiving cisplatin- or carboplatin-based chemotherapy for advanced stage NSGCT at our institute from 1994 to 2015. Clinical and pathological parameters such as the histology of orchidectomy, RPLND and metastasectomy, serum tumor markers, and the pre and post chemotherapy retroperitoneal lymph node size were recorded. Results: Seventy-two patients with a mean age of 28 years underwent PC-RPLND. Of the various variables evaluated, only percentage change in nodal size was found to be statistically significant in predicting necrosis (P = 0.004). A decrease of 75% was found to predict the necrosis with a specificity of 100%. There was 84.6% concordance between the histology of RPLND and that of metastasectomy. Conclusion: A 75% reduction in tumor size is highly predictive of absence of viable tumor or teratoma, however larger series are required to confirm these findings. RPLND histopathologies have a high concordance with metastasectomy histology and thus can be used as a guide to tailor further management.
