| Popis: | Simple Summary The concept of locoregional lymphadenectomy (LND) in adrenocortical cancer (ACC) has gained interest in recent years, but its definite prognostic and therapeutic significance remains to be established. We undertook a systematic review and meta-analysis to determine the oncologic value of LND in ACC, focusing on overall survival as the primary endpoint. Eleven studies were identified and five were included in the meta-analysis, all of them were retrospective studies. Three studies reported the impact of LND on disease-specific survival in patients with stage I–III ACC and revealed a survival benefit of LND, whereas studies including patients with stage I–IV ACC (N = 2) did not show a survival benefit of LND. In summary, our results demonstrate an oncologic benefit of LND in patients undergoing curative-intended surgery for at least localized ACC (stage I–III). Abstract (1) Background: Locoregional lymphadenectomy (LND) in adrenocortical carcinoma (ACC) may impact oncological outcome, but the findings from individual studies are conflicting. The aim of this systematic review and meta-analysis was to determine the oncological value of LND in ACC by summarizing the available literature. (2) Methods: A systematic search on studies published until December 2020 was performed according to the PRISMA statement. The primary outcome was the impact of lymphadenectomy on overall survival (OS). Two separate meta-analyses were performed for studies including patients with localized ACC (stage I–III) and those including all tumor stages (I–IV). Secondary endpoints included postoperative mortality and length of hospital stay (LOS). (3) Results: 11 publications were identified for inclusion. All studies were retrospective studies, published between 2001–2020, and 5 were included in the meta-analysis. Three studies (N = 807 patients) reported the impact of LND on disease-specific survival in patients with stage I–III ACC and revealed a survival benefit of LND (hazard ratio (HR) = 0.42, 95% confidence interval (95% CI): 0.26–0.68). Based on results of studies including patients with ACC stage I–IV (2 studies, N = 3934 patients), LND was not associated with a survival benefit (HR = 1.00, 95% CI: 0.70–1.42). None of the included studies showed an association between LND and postoperative mortality or LOS. (4) Conclusion: Locoregional lymphadenectomy seems to offer an oncologic benefit in patients undergoing curative-intended surgery for localized ACC (stage I–III). |
