AbstractContext: Guidelines recommend primary retroperitoneal lymph node dissection (RPLND) as a treatment option for tumour marker-negative stage II nonseminomatous germ cell tumour (NSGCT). Objective: To review the literature on oncological outcomes for men with stage II NSGCT treated with RPLND. Evidence acquisition: A systematic review of studies describing clinicopathological outcomes following primary RPLND in stage II NSGCT was conducted in the MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews databases according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. Baseline data, perioperative and postoperative parameters, and oncological outcomes were collected. Evidence synthesis: In total, 12 of 4387 studies were included, from which we collected data for 835 men. Among men with clinical stage II NSGCT, pathological stage II was confirmed in 615 of 790 patients (78%). Most studies administered adjuvant chemotherapy in cases with large lymph nodes, multiple affected lymph nodes, or persistently elevated tumour markers. Recurrence was observed in 12-40% of patients without adjuvant chemotherapy and 0-4% of patients who received adjuvant chemotherapy. Conclusions: The literature describing RPLND in clinical stage II NSGCT is heterogeneous and no meta-analysis was possible, but RPLND can provide accurate staging and may be curative in selected patients. Patient summary: We reviewed the literature to summarise results after surgical removal of enlarged lymph nodes in the back of the abdomen in men with testis cancer. This procedure provides accurate information on how far the cancer has spread and may provide a cure in selected patients.
