RESUMO
BACKGROUND: Many studies have investigated the efficacy and safety of lentinan combined with cisplatin versus cisplatin alone for controlling malignant pleural effusion (MPE). This study is a meta-analysis of available evidence. MATERIALS AND METHODS: Seventeen studies reporting lentinan combined with cisplatin versus cisplatin alone for controlling MPE were reviewed. Pooled odds ratios and hazard ratio with 95% confidence intervals were calculated using the fixed effects model of meta-analysis. RESULTS: The overall response rate (ORR) of lentinan combined with cisplatin for controlling MPE was significantly higher than that of cisplatin alone (P < 0.001). In addition, lentinan combined with cisplatin showed a better benefit of quality of life (QOL) compared with cisplatin alone (P < 0.001). The main adverse effects (AEs) found in the control plan were hematological reactions, nausea/vomiting, chest pain and fever. However, the presence of lentinan did not have an extra influence on the incidence of AEs (P > 0.05). CONCLUSIONS: Intrapleural injection of lentinan combined with cisplatin had a better benefit of ORR and QOL for controlling MPE, compared with cisplatin alone. Moreover, lentinan combined with cisplatin had a similar incidence of AEs with cisplatin alone.
