Assessing the Comparative Efficacy of Sentinel Lymph Node Detection Techniques in Vulvar Cancer: Protocol for a Systematic Review and Meta-Analysis.

This systematic review and meta-analysis protocol aims to evaluate the comparative efficacy of different sentinel lymph node (SLN) detection techniques in the management of vulvar cancer. Vulvar cancer, though rare, predominantly affects older women and requires effective management strategies. The SLN technique has become a standard approach for early-stage cases, offering reduced morbidity compared to complete lymphadenectomy. Currently, various SLN detection methods exist, including the use of Technetium-99m (Tc99m), Indocyanine Green (ICG), and superparamagnetic iron oxide (SPIO), but there is a lack of comprehensive comparison of their efficacy. This review will systematically search relevant databases, including PubMed, Scopus, Cochrane, Web of Science and Embase following PRISMA guidelines, to gather data from clinical trials. The primary outcome will be the detection rates of SLN techniques with secondary outcomes examining patient characteristics and procedural factors. The analysis will utilize random-effects models to compare detection rates across studies. The results of this study aim to provide insights into the optimal SLN detection method with potential implications for clinical practice guidelines in vulvar cancer management. The protocol is registered under the PROSPERO registration number CRD42024590774.
