Primary retroperitoneal lymph node dissection for clinical stage II seminoma: A systematic review and meta-analysis of safety and oncological effectiveness.

To evaluate the oncological outcomes and safety of primary retroperitoneal lymph node dissection (RPLND) in patients with clinical stage (CS) II seminomatous testicular germ cell tumor (TGCT). A literature search using PubMed, Scopus, and Cochrane Library was conducted on July 2023 to identify relevant studies according to the Preferred Reporting Items for Systematic Review and Meta Analysis (PRISMA) guidelines. The pooled recurrence rate and treatment-related complications were calculated using a random effects model. Overall 8 studies published between 1997 and 2023 including a total of 355 patients were selected for systematic review and meta-analysis with the overall median follow-up of 38 months. The overall and infield recurrence rate were 0.14 (95% CI: 0.08-0.22) and 0.04 (95% CI: 0.00-0.11), respectively. The overall pooled rate of ≥ Clavien Dindo grade III complications was 0.04 (95% CI: 0.01-0.10); there was no significant heterogeneity (I^2 = 35.10%, P = 0.19). Antegrade ejaculation was preserved with the overall pooled rate of 0.98 (95% CI: 0.95-1.00); there was no significant heterogeneity on Chi-square and I2 tests (I^2 = 0.00%, P = 0.58). Primary RPLND is a safe and effective treatment option for patients with CS II seminomatous TGCT resulting highly promising cure rates combined with low treatment-associated adverse events, at medium-term follow-up. However, owing to the lack of comparative studies to the current standard of care and the limited follow-up, individual decision must be made with the informed patient in a shared decision process together with a multidisciplinary team.
