Introduction: Chemotherapy, postchemotherapy retroperitoneal lymph node dissection (pcRPLND), and metastasectomy remain the standard of care for the management of advanced nonseminomatous germ cell tumor (NSGCT). Methods: We retrospectively studied 73 patients who had pcRPLND at a single tertiary-care center (2003-2022). Surgical and clinicopathological features and oncological outcomes are presented. Results: The mean age was 28.27 years (15-48). Three-fourths had Stage III disease at diagnosis. International Germ Cell Cancer Collaborative Group risk stratification was 54.54 and 21.21 in intermediate risk, and poor risk, respectively. Sixty-two patients had Standard, 7 had Salvage and 4 underwent Desperation pcRPLND. Eleven patients (15.06) required adjunctive procedures. Thirteen patients (17.8) had ≥ class 3 Clavien-Dindo complications and postoperative mortality occurred in 5 (6.8) patients. The histopathologies (HPE) of the pcRPLNDs were necrosis, teratoma, and viable tumor in 39.7, 45.2, and 15.1, respectively. Seven patients underwent metastasectomy. An 85 size reduction in the size of RPLN predicted necrosis. There was 71.4 concordance between pcRPLND and metastasectomy HPEs. The median follow-up was 26.72 months (inter-quartile range - 13.25-47.84). The 2-year recurrence-free survival (RFS) rate was 93 (95 confidence interval [CI]-83-97) and the overall survival (OS) rate was 90 (95 CI-80-95). This is the largest series of pcRPLND for NSGCT in India to our knowledge. Conclusion: Although most of the cohort belonged to stage III, an RFS and OS rate of >90 at 2 years was achieved. We believe that successful management of postchemotherapy residual masses in NSGCT is contingent on the availability of multidisciplinary expertise and is therefore best done at tertiary-care referral centers., Author(s): Rakesh Kumar [1,2]; Madhuri Evangeline Sadanala [2]; Santosh Nagasubramanian [2]; Anjana Joel [3]; Arun Joseph Philip George [2]; S Mahasampath Gowri [4]; Partho Mukherjee [2]; Ashish Singh [3]; Rajiv [...]
