Purpose
Recent studies have investigated if the sodium fluorescein-guided (SFg) improves the extent of resection of BMs when compared to standard white light (sWL). Therefore, we aimed to assess the comparative efficacy and safety of SFg and sWL for resection of BMs.
Methods
We searched Medline, Embase, and Cochrane Library databases following Cochrane and PRISMA guidelines for studies reporting comparative data of SFg and WL resection of BMs. We pooled odds ratios (OR) with 95% confidence intervals under random effects and applied I² statistics and leave-one-out sensitivity analysis to assess heterogeneity. I² > 40% was considered significant for heterogeneity.
Results
Five studies involving 816 patients were included, of whom 390 underwent BMs resection with SFg and 426 with sWL, and ages ranging between 26 and 86.2 years old. Analysis revealed a statistically significant higher likelihood of complete resection in the SFg group when compared to the sWL group (OR = 2.15, 95%CI: 1.18–3.92, p = 0.01; I² = 47%). Sensitivity analysis revealed a consistent result in all five scenarios, with low heterogeneity in two of the five scenarios. Three studies reported significant improvement in OS in the SFg group, and the qualitative assessment of complications and procedure-related mortality did not provide sufficient information for conclusions.
Conclusion
This systematic review and meta-analysis identified a higher likelihood of complete resection in the SFg group when compared to the standard sWL group. This study is the first to directly compare the impact of SFg and sWL on resection outcomes for BMs.
