Purpose It remains undetermined whether cisplatin and carboplatin are equally effective for advanced non–small-cell lung cancer (NSCLC). We therefore did a meta-analysis of trials that compared cisplatin-based chemotherapy with carboplatin-based chemotherapy. Methods We performed a literature search to identify trials that had investigated the substitution of carboplatin for cisplatin in the treatment of advanced NSCLC. We evaluated these trials for inclusion, rated methodologic quality, and abstracted relevant data. Results Of 1,191 reports, eight trials (2,948 patients) were identified, five of which investigated drug regimens containing platinum plus a new agent. Cisplatin-based chemotherapy produced a higher response rate, but the survival advantage was not significant (hazard ratio = 1.050; 95% CI, 0.907 to 1.216; P = .515). Subgroup analysis revealed that combination chemotherapy consisting of cisplatin plus a new agent yields 11% longer survival than carboplatin plus the same new agent (hazard ratio = 1.106; 95% CI, 1.005 to 1.218; P = .039). Patients on cisplatin-based chemotherapy frequently developed nausea and vomiting; thrombocytopenia was more frequent during carboplatin-based chemotherapy. No significant difference in treatment-related mortality was observed. Conclusion We found that combination chemotherapy consisting of cisplatin plus a new agent yields a substantial survival advantage compared with carboplatin plus a new agent in patients with advanced NSCLC, although we failed to find any survival difference in an analysis that included both new and old agents. The strength of our conclusion is limited because we used abstracted data, and careful interpretation is thus required. Nevertheless, our results raise a critical point that needs to be evaluated in future studies.

No head-to-head trials have compared the efficacy and safety of nivolumab (Niv) plus ipilimumab (Ipi) combination therapy (Niv+Ipi) and existing regimens with immunotherapies approved as first-line treatment in patients with programmed cell death ligand 1 (PD-L1)-positive previously untreated advanced non-small cell lung cancer (NSCLC). We conducted a network meta-analysis of four relevant Phase Ⅲ trials to compare the efficacy and safety of Niv+Ipi, pembrolizumab (Pem) plus platinum-based chemotherapy (PBC) (Pem+PBC), Pem, Niv, or PBC using Bayesian analysis. The primary efficacy endpoint was progression-free survival (PFS) in patients with advanced NSCLC with PD-L1 expression ≥1%. The primary safety endpoint was the incidence of Grade 3–5 drug-related adverse events (G3–5AEs). Efficacy and safety were ranked using surface under the cumulative ranking curve (SUCRA). With regard to PFS, Niv+Ipi was inferior to Pem+PBC, and superior to Pem, Niv, or PBC alone. SUCRA ranking showed Pem+PBC had the highest efficacy for PFS, followed by Niv+Ipi, Niv, PBC, and Pem. The safety outcome analysis revealed Niv+Ipi was generally well tolerated compared to existing immunotherapy regimens. These results provide clinical information regarding the efficacy and safety of Niv+Ipi and indicate the possibility of the Niv+Ipi combination as a new therapeutic option in PD-L1-positive advanced NSCLC.

BackgroundThe immunotherapy plus chemotherapy combination is one of the most promising treatments in advanced non-small-cell lung cancer (NSCLC). Immunotherapy often causes immune-related adverse events (irAEs), which have been reported to be associated with the good clinical outcomes. However, the effects of immunotherapy plus chemotherapy remain unknown. In this study, we investigated the association between irAEs caused by immunotherapy plus chemotherapy and clinical efficacy in patients with advanced NSCLC.Materials and MethodsWe retrospectively analyzed the data of patients with advanced NSCLC, who received a combination of immunotherapy plus chemotherapy at six institutions in Japan between January 2019 and September 2019. We examined the effect of irAEs on various clinical outcomes.ResultsWe included 70 patients with advanced NSCLC. Patients were divided into two groups: patients with irAEs and patients without irAEs. Patients with irAEs had significantly longer progression-free survival than those without irAEs on univariate (hazard ratio 0.53, 95% confidence interval 0.30–0.93, p = 0.026) and multivariate (hazard ratio 0.53, 95% confidence interval 0.29–0.97, p = 0.041) analyses. In addition, patients with grade 1–2 irAEs (mild irAEs) had significantly longer progression-free and overall survival than those with grade 3-5 irAEs (severe irAEs) or without irAEs on univariate (398 days versus 189 days, respectively; p = 0.0061) and multivariate (not reached versus 412 days, respectively; p = 0.021) analyses.ConclusionPatients with NSCLC who experienced mild irAEs showed better response to treatment with immunotherapy plus chemotherapy than those with severe irAEs or without irAEs. Further large-scale research is warranted to confirm these findings.

Recent advances have shown that immune checkpoint inhibitors are emerging as promising therapeutic targets to improve the quality of life in cancer patients. This meta-analysis was conducted to evaluate the influence of Kanglaite injection (KLTi) combined with chemotherapy versus chemotherapy alone on clinical efficacy, immune function, and safety for the treatment of advanced non-small-cell lung cancer (NSCLC). Several electronic databases, including PubMed, Web of Science, Wan-Fang, VMIS, EMBASE, Cochrane Library, CNKI, CBM, and MEDLINE, as well as grey literatures, were comprehensively searched from January 2000 to November 2019. Randomized controlled trials (RCTs) reporting outcomes of clinical efficacy and immune function were collected according to their inclusion and exclusion criteria. Cochrane Reviewers’ Handbook 5.2 was applied to assess the risk of bias of included trials. STATA 13.0 and Review Manager 5.3 software were used for meta-analysis. Twenty-five RCTs comprising 2151 patients meeting the inclusion criteria were identified. Meta-analysis showed that compared with chemotherapy alone, KLTi plus the same chemotherapy significantly improved clinical efficacy, including complete response, partial response, stable disease, and progressive disease, as well as immune function, including CD3+, CD4+, CD8+, and CD4+/CD8+. There was a significant reduction in nausea and vomiting, thrombocytopenia, and leukopenia in combination treatments. However, the outcomes were limited because of the low quality and small sample size of the included studies. In conclusion, this work might provide beneficial evidence of KLTi combined with chemotherapy for improving clinical efficacy and immune function, as well as reducing the incidence of adverse events in advanced NSCLC patients. KLTi might be a beneficial therapeutic method for the treatment of advanced NSCLC. Due to the quality of the data, more rigorous and well-designed RCTs are needed to confirm these findings.

Platinum-based chemotherapy is one of the standard treatments for non-small-cell lung cancer (NSCLC), while its high toxicity and limited clinical effects raise big concerns. Shenfu injection (SFI) has been commonly used as an adjutant chemotherapy drug for NSCLC in China. We ascertained the beneficial and adverse effects of SFI in combination with platinum-based chemotherapy for advanced NSCLC by using meta-analysis methods. The randomized controlled trials (RCTs) involving advanced NSCLC treatment with SFI plus platinum-based chemotherapy versus chemotherapy alone were searched on 6 medical databases up to February 2017. Cochrane handbook 5.1.0 was applied to assess the quality of included trials and RevMan 5.3 software was employed for data analysis. 23 RCTs including 1574 patients met our inclusion criteria. We evaluated the following outcome measures: objective tumor response (ORR), disease control rate (DCR), Karnofsky performance score (KPS), adverse effects, and indicators of cellular immune function. The meta-analysis indicated that SFI plus platinum-based chemotherapy may benefit the patients with NSCLC on attenuated synergies of chemotherapy. These findings need to be confirmed by further rigorously designed high-quality and large-scale RCTs.

Purpose. To evaluate the efficacy of Brucea javanica oil emulsion injection (BJOEI) in patients with advanced non-small-cell lung cancer (NSCLC) during chemotherapy. Method. Electronic database of EMBASE and PubMed and the conference proceeding of ASCO, CNKI, CBMdisc, VIP, and Wanfang database were searched to select RCTs comparing BJOEI plus chemotherapy with chemotherapy alone in the treatment of advanced NSCLC, until June 1, 2016. Two reviewers independently performed the analysis according to the inclusion and exclusion criteria. Review Manager 5.3 and STATA 12.0 were employed for data analysis. Result. Twenty-one studies including 2234 cases were included. The pooled result indicated that there were significant differences in ORR (RR=1.25; 95% CI: 1.14–1.36; P<0.00001), improvement of QOL (RR=1.87; 95% CI: 1.63–2.15; P<0.00001), nausea and vomiting (RR=0.67; 95% CI: 0.46–0.98; P=0.04), leukopenia (RR=0.63; 95% CI: 0.52–0.75; P<0.00001), but there was no difference in thrombocytopenia (RR=0.78; 95% CI: 0.49–1.23; P=0.29). Begg’s funnel plot and Egger’s test indicated that no publication bias was found. The sensitivity analysis suggested the stability of the pooled result. Conclusion. The addition of BJOEI can enhance efficacy, improve QOL, and decrease incidence of nausea and vomiting and leukopenia for advanced NSCLC patients. However, higher quality RCTs are needed to further confirm this finding.

Programmed cell death-ligand 1 (PD-L1) has emerged as a potential biomarker for selection of patients more likely to respond to immunotherapy and as a prognostic factor in non-small cell lung cancer (NSCLC). In this network meta-analysis, we aimed to evaluate the efficacy of first-line anti-PD-(L)1 monotherapy in advanced NSCLC patients with high PD-L1 expression (≥50%) compared to platinum-based chemotherapy. We also evaluated efficacy outcomes according to tumor mutational burden (TMB). To that end, we conducted a systematic review. Six clinical trials with 2111 patients were included. In head-to-head comparisons, immunotherapy showed a significant improvement in progression-free survival (PFS: HRpooled = 0.69, 95% CI: 0.52–0.90, p = 0.007), overall survival (OS: HRpooled = 0.69, 95% CI: 0.61–0.78; p < 0.001) and overall response rate (ORR) (Risk ratio (RR)pooled = 1.354, 95% CI: 1.04–1.762, p = 0.024). In the assessment of relative efficacy for PFS through indirect comparisons, pembrolizumab (results from KEYNOTE-024) ranked highest followed by cemiplimab and atezolizumab, with statistical significance determined for some of the drugs. In terms of OS, cemiplimab ranked highest followed by atezolizumab and pembrolizumab, although non-significant OS was determined for these drugs. In conclusion, PD-(L)1 inhibitor monotherapy improves efficacy outcomes in the first line setting of advanced NSCLC patients with high PD-L1 expression. Evaluations with longer follow up are still needed to determine the superiority of any specific drug.

Objective To assess the efficacy and toxicity of anlotinib for the treatment of refractory advanced non-small-cell lung cancer (NSCLC). Methods We systematically searched databases for randomized controlled trials on anlotinib treatment for patients with advanced NSCLC published until November 6, 2020. Articles were assessed and data were extracted independently by two investigators. Further, we analyzed hazard ratios (HRs) for progression-free and overall survival (PFS and OS, respectively). In addition, we analyzed risk ratio (RR) for overall response and disease control rates (ORR and DCR, respectively) and the odds ratio (OR) for the main adverse events (AEs) using RevMan 5.3 software. Results This analysis included 594 patients from three clinical studies. The pooled HRs for PFS and OS were 0.27 (95% confidence interval (CI): 0.22–0.33, P < 0.001) and 0.68 (95% CI: 0.56–0.83, P < 0.001), respectively, indicating that anlotinib administration significantly improved PFS and OS in patients with advanced NSCLC. The pooled RRs for ORR and DCR were 11.62 (95% CI: 2.75–49.14, P < 0.001) and 2.30 (95% CI: 1.91–2.77, P < 0.001), respectively, indicating that anlotinib administration in patients with advanced NSCLC improved ORR and DCR. The pooled OR for AEs of grade 3 or higher was 2.94 (95% CI: 1.99–4.35, P < 0.001), indicating that AEs of grade 3 or higher were more prevalent in the anlotinib group than in the placebo group. Conclusion Anlotinib, an effective choice of third- or later line therapy for patients with refractory advanced NSCLC, provides clinical benefits in terms of PFS, OS, ORR, and DCR. AEs associated with anlotinib were tolerable.
