Objective. Bevacizumab was currently available for nonsquamous non-small-cell lung cancer (NSqNSCLC) patients and has been studied in several randomized controlled trials (RCTs) for treatment of these patients. This meta-analysis summarizes the most up-to-date evidences regarding the effects and adverse reactions of bevacizumab in the treatment of NSqNSCLC patients. Methods. The authors searched for RCTs from electronic database including PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. Experimental arm was defined as the bevacizumab-containing group and the control arm as the bevacizumab-free group. Data of objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and adverse reactions were synthetically extracted. A protocol for this meta-analysis has been registered on PROSPERO (http://www.crd.york.ac.uk/prospero). Results. Ten RCTs that involved a total of 3134 patients were included. The experimental group was associated with significant superior ORR (RR 1.63, 95% CI 1.24 to 2.14, P < 0.001 ), OS (HR 0.90, 95% CI 0.82 to 0.99, P < 0.001 ), and prolonged PFS (HR 0.68, 95% CI 0.62 to 0.74, P < 0.001 ) compared to the control. No significant difference was observed regarding DCR (RR 1.13, 95% CI 0.99 to 1.30, P = 0.08 ). The experimental group showed higher rate of hypertension (RR 6.91, 95% CI 4.62 to 10.35, P < 0.00001 ) and hemorrhagic events (RR 3.07, 95% CI 1.78 to 5.30, P < 0.0001 ) than the control group. The experimental group showed lower rate of anemia (RR 0.72, 95% CI 0.55 to 0.96, P = 0.02 ) than the control group. No significant difference was observed regarding treatment-related adverse event grade 3-5 (TRAE3-5) (RR 1.23, 95% CI 0.99 to 1.53, P = 0.06 ), thrombocytopenia (RR 1.11, 95% CI 0.92 to 1.33, P = 0.29 ), and neutropenia (RR 1.11, 95% CI 0.88 to 1.40, P = 0.36 ). Conclusion. This meta-analysis showed that bevacizumab could increase ORR, OS, and prolonged PFS for treatment of NSqNSCLC patients. However, no significant improvement in DCR was observed and bevacizumab could increase the rate of hypertension and hemorrhagic events. Bevacizumab was an acceptable option for NSqNSCLC patients. This trial is registered with PROSPERO registration number: CRD42021226790.

Background. Compound Taxus chinensis capsule (CTCC), an antitumor Chinese patent medicine, has been commonly prescribed as an adjunctive agent to chemotherapy for the management of non-small-cell lung cancer (NSCLC); however, the effects of CTCC added to chemotherapy for NSCLC patients have never been comprehensively evaluated or summarized. Purpose. To assess the synergistic effects of CTCC and chemotherapy on NSCLC. Study Design. Evidence-based study, systematic review, and quantitative meta-analysis. Methods. This systematic review and meta-analysis was implemented in accordance with the PRISMA (Preferred Reported Items for Systematic Review and Meta-Analysis) guidelines. Eight databases including China National Knowledge Infrastructure, SINOMED, China Biomedical Literature Database, Wanfang Database, VIP, PubMed, Cochrane Library, and EMBASE were searched for relevant RCTs from their inception until May 24, 2021, and hand-searching was also carried out to identify additional studies. All randomized controlled trials (RCTs) that compared CTCC combined with chemotherapy versus chemotherapy alone were included in our study. The Cochrane Risk-of-Bias tool was used to determine the risk of bias and methodological quality of the included RCTs. Review Manager 5.3 software was used for comprehensive analysis. The primary outcome measure for this study was the disease control rate (DCR), and the secondary outcomes included the objective response rate (ORR), adverse reactions, and quality of life (QOL). Results. Six RCTs with a total sample size of 410 were finally included. The pooled data showed that, compared with chemotherapy alone, CTCC combined with chemotherapy significantly improved DCR (RR = 1.15, 95% CI: 1.06–1.25, P  = 0.006), ORR (RR = 1.38, 95% CI: 1.18–1.63, P  < 0.00001), and QOL (MD = 8.69, 95% CI: 7.26–10.13, P  < 0.006) and reduced the incidence of total adverse reactions (RR = 0.48, 95% CI: 0.38–0.60, P  < 0.00001). The subgroup analyses indicated that CTCC plus chemotherapy significantly improved gastrointestinal reactions ( P  = 0.004), leukopenia ( P  = 0.0009), thrombocytopenia ( P  = 0.01), rash ( P  = 0.002), and fever ( P  = 0.007). Conclusion. Based on the available evidence, compared with chemotherapy alone, CTCC used as an adjunctive agent to chemotherapy for NSCLC can improve the clinical efficacy and quality of life and decrease the likelihood of adverse reactions, suggesting that CTCC might be an effective and safe adjunctive medicine to chemotherapy for NSCLC. However, considering the relatively small sample size and the inherent imperfections of the included randomized controlled trials, more high-quality clinical trials with longer follow-up time are needed to further assess the efficacy and safety of this combined treatment regimen.
