Comparison of the oncological, perioperative and functional outcomes of partial nephrectomy versus radical nephrectomy for clinical T1b renal cell carcinoma: A systematic review and meta-analysis of retrospective studies
2019
Abstract Objective To conduct a meta-analysis assessing the perioperative, functional and oncological outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for T1b tumours. The primary endpoints were the oncological outcomes. The secondary endpoints were the perioperative and functional outcomes. Methods A systematic literature review was performed by searching multiple databases through February 2019 to identify eligible comparative studies according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Identified reports were assessed according to the Newcastle-Ottawa Scale (NOS) for nonrandomized controlled trials. Results Overall, 13 retrospective cohort studies were included in the analysis. Patients undergoing PN were younger (weighted mean difference [WMD] –3.49 year, 95% confidence interval [CI] –5.16 to –1.82; p Conclusion PN is an effective treatment for T1b tumours because it offers similar surgical morbidity, equivalent cancer control, and better renal preservation compared to RN.
