The effects of incretin-based therapies on weight reduction and metabolic parameters in children with obesity: A systematic review and meta-analysis.

BACKGROUND: Growing evidence indicates that incretin-based therapies (IBTs), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), and dipeptidyl peptidase-4 inhibitors (DPP4is) are effective and safe for treating pediatric obesity patients with or without type 2 diabetes. Therefore, we aimed to perform a systematic review and meta-analysis for updating current evidence. METHODS: We searched the PubMed, the Cochrane Library, and the EMBASE database for articles published until September 15, 2023, and limited to randomized control trials. The primary outcomes were changed from baseline in weight metrics and the cardiometabolic profile. A random effects model will be used, as high heterogeneity is expected. All analyses were performed using STATA 17.0. RESULTS: Fifteen trials with a total number of 1286 participants were included in our meta-analysis. Overall, the mean difference in weight change between the IBTs group and the control group was -2.89 kg (95% confidence interval, -5.12 to -0.65, p = 0.011). Additionally, IBTs significantly reduced the HbA1c level and fasting plasma glucose by 0.37% and 6.99 mg/dl, compared with control groups. IBTs showed a little increased risk of GI side effects and hypoglycemia events, but none of the severe hypoglycemia events were occurred in IBTs group. CONCLUSIONS: Our study results have proved that GLP-1 RAs are safe, acceptable, and effective in weight reduction and sugar control for children with obesity. In addition, DPP-4is seems to have no effect on glycemic control and weight loss in childhood obesity. Further research is needed to confirm these findings, especially in younger children.

S-Adenosylmethionine (SAMe) as an adjuvant therapy for patients with depression: An updated systematic review and meta-analysis.

BACKGROUND: Major depressive disorder (MDD) is an intractable disease requiring long-term treatment. S-adenosyl-L-methionine (SAMe), a natural substance, has antidepressant effects, but the exact effect remains unclear. This study examines the evidence concerning the efficacy of SAMe as a monotherapy or in combination with antidepressants. METHODS: The PubMed, EMBASE, and Cochrane electronic databases were searched for meta-analyses of randomized controlled clinical trials (RCTs) until June 30, 2023. We performed a systematic review and meta-analysis of the enrolled trials that met the inclusion criteria, with the aim to compare the effects of SAMe to those of a placebo or active agents, or SAMe combined with other antidepressants in the treatment of MDD. RESULTS: Fourteen trials, with a total of 1522 subjects, were included in this review. The daily dose of SAMe varied from 200 to 3200 mg and the study duration ranged between 2 and 12 weeks. The results of SAMe versus placebo as a monotherapy, SAMe versus imipramine or escitalopram as a monotherapy, and SAMe versus placebo as an adjunctive therapy, showed no significant difference in depression with SAMe compared to the comparison treatment. CONCLUSIONS: SAMe may provide relief of depression symptoms similar to imipramine or escitalopram. However, the results of the comparisons should be interpreted with caution due to the small number of studies and the large range of SAMe doses that were used in the included trials. Therefore, we recommend that patients discuss treatment options with their doctor before taking SAMe.

Efficacy and Safety of Programmed Death-1/Programmed Death-Ligand 1 Inhibitor for Metastatic Urothelial Carcinoma: A Systematic Review and Meta-Analysis.

Objective: The purpose of this study was to evaluate the efficacy and safety of programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors for the treatment of metastatic urothelial carcinoma (mUC). Methods: A literature search was conducted of PubMed, EMBASE, and the Cochrane Library and was limited to the English literature. Randomized controlled trials (RCTs) published up to July 2022 were considered for inclusion. The outcomes were progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and grade ≥ 3 treatment-related AEs (TRAE). Subgroup analysis was performed based on the PD-L1 expression status, and the differences between first- and second-line PD-1/PD-L1 inhibitors were estimated. Results: We included five RCTs comprising 3584 patients in the analysis. Compared with chemotherapy alone, the use of PD-1/PD-L1 inhibitors as monotherapy did not significantly prolong OS [hazard ratios (HR), 0.90; 95% CI, 0.81-1.00] or PFS (HR, 1.12; 95% CI, 0.95-1.32). However, the PD-1/PD-L1 inhibitor combined with chemotherapy significantly improved both OS (HR, 0.85; 95% CI, 0.74-0.96) and PFS (HR, 0.80; 95% CI, 0.71-0.90). Additionally, subgroup analysis showed that in mUC with PD-L1 expression ≥ 5%, treatment with the PD-1/PD-L1 inhibitor alone did not reduce the risk of death. Safety analysis showed that the PD-1/PD-L1 inhibitor alone did not significantly increase the incidence rates of grade ≥ 3 TRAEs. Conclusions: The results show that use of the PD-1/PD-L1 inhibitor alone as first-line treatment is similar to chemotherapy in terms of both survival and response rates. However, the PD-1/PD-L1 inhibitor plus chemotherapy has a significant benefit in terms of PFS or OS. Nonetheless, more RCTs are warranted to evaluate efficiency and safety in the combination regimen of chemotherapy and PD-1/PD-L1 inhibitors.

Efficacy and safety of cyclin-dependent kinase 4/6 inhibitor in patients with advanced breast cancer: A real-world experience.

BACKGROUND: Cyclin-dependent kinases 4 and 6 inhibitors (CDK4/6i) have been shown to improve progression-free survival (PFS) in patients with metastatic breast cancer (MBC) in randomized control trials. This study aimed to evaluate the efficacy and safety of CDK4/6i in patients with advanced breast cancer (ABC) in a clinical setting. METHODS: Consecutive patients with ABC were treated between October 2019 and March 2023 at Taipei Tzu Chi Hospital, Taiwan. Patients who had received at least one dose of CDK4/6i were included in this retrospective study. The main outcome of this study was efficacy based on the treating physicians' assessments in terms of PFS, and overall survival (OS), as well as the factors associated with patient outcome. The secondary outcome was safety. RESULTS: A total of 85 patients were included in the analysis, with a mean age of 66.8 years. After a median follow-up of 16.1 months, the median PFS was 28.4 months (95% CI: 22.5-33.6) and the median OS could not yet be estimated. The most common adverse events (AE) were fatigue (50.8%), anorexia (45.9%), and leukopenia (44.7%). In multivariable analysis, treatment with CDK4/6i with any grade AE or response to treatment effect (CR/PR) was an independent predictor for longer PFS (hazard ratio [HR] = 0.27, 95% CI: 0.11-0.68; HR = 0.21, 95% CI: 0.06-0.67; p < 0.05). CONCLUSION: CDK4/6i administered in a real-world setting exhibits a similar survival benefit with the clinical trials.

Efficacy and safety of anaplastic lymphoma kinase inhibitors for non-small cell lung cancer: A systematic review and network meta-analysis.

BACKGROUND: To assess the efficacy and safety of anaplastic lymphoma kinase inhibitors (ALKIs) for the treatment of advanced-stage ALK rearrangement-positive non-small cell lung cancer (NSCLC). METHODS: We searched PubMed, EMBASE, and the Cochrane Library for randomized controlled trials (RCTs) that included patients with ALK-positive NSCLC receiving ALKIs. The outcomes of the study included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and treatment-related adverse events (TRAEs) of grade ≥3. RESULTS: A total of 12 RCTs consisting of 3169 patients with eight treatment options were included in this study. Our results showed that ALKIs have superior efficacy in OS, PFS, and ORR than chemotherapy or crizotinib (first-generation ALKI). Our study showed that only alectinib has a significant improvement in OS compared to chemotherapy (hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.40-0.94). Alectinib appeared to have better OS than crizotinib (HR, 0.66; 95% CI, 0.45-0.95). Ensartinib has a significant PFS advantage over alectinib (HR, 0.62; 95% CI, 0.40-0.96). The surface under the ranking curve indicated that ensartinib (99.0%) was the highest rank regarding PFS. Moreover, both ensartinib and ceritinib showed significantly higher TRAEs of grade ≥3 compared with chemotherapy (risk ratios [RR], 2.74; 95% CI, 1.45-5.18; RR, 1.80; 95% CI, 1.26-2.57, respectively). CONCLUSIONS: These results indicated that alectinib could be associated with the best therapeutic efficacy and well-tolerance AEs in the treatment of ALK-positive NSCLC.

Statin Use and Delirium Risk: An Updated Systematic Review and Meta-Analysis.

BACKGROUND: Findings on the association of statin use with delirium risk are inconsistent. THE STUDY QUESTION: Is statin use associated with delirium risk? STUDY DESIGN: We searched PubMed, the Cochrane Library, and the EMBASE database, limiting the search to human patients and articles in English published until December 31, 2021. The effect size and 95% confidence interval (CI) were defined as the odds ratio (OR) and 95% CI, respectively, to indicate the difference in the incidence of delirium between statin use and nonuse groups. A random-effects model was selected in the case of high heterogeneity of study populations. We used funnel plots, Egger test, Duval and Tweedie trim-and-fill approach, and the classic fail-safe N to assess publication bias. RESULTS: Of a total of 264 identified studies, 13 were selected for the qualitative review-4 RCTs and 9 observational cohort studies. Statin use was not associated with low delirium risk (pooled OR, 0·82; 95% CI, 0·64-1·04; P = 0·09). Substantial statistical heterogeneity was observed ( I2 , 90%). Visual inspection of the funnel plot of ORs from the studies revealed symmetry. Using the Grading of Recommendations Assessment, Development, and Evaluation approach, we assigned the evidence a rating of C and a weak recommendation for this review. CONCLUSIONS: Statin use is not associated with delirium risk. More comprehensive RCTs are required to confirm the results.

Association between proton-pump inhibitors and the risk of gastric cancer: a systematic review and meta-analysis.

BACKGROUND: Proton pump inhibitors (PPIs) may be associated with gastric cancer, but studies in recent years have proven still inconsistent results. We conducted a systematic review and meta-analysis to investigate the association between PPI use and gastric cancer. METHODS: Pubmed, EMBASE, and Cochrane library were searched for studies published up to 15th February 2022. Studies on the association between PPI and the risk of gastric cancer, pooled the odds ratios (ORs) using a random-effects model. The subgroup analysis for study design, site of gastric cancer, and the duration of PPI use was performed. Heterogeneity was assessed using the I2 and Cochran's Q statistics. RESULTS: Sixteen cohorts and case-control studies were included. PPI use was significantly associated with gastric cancer (OR: 1.75, 95% CI: 1.28-2.40). The subgroup analysis found a significant risk increase in non-cardia gastric cancer (OR: 2.14, 95%CI: 1.50-3.07). There was no duration-dependent effect of PPI use and gastric cancer risk (< 1 year: OR: 2.56, 95% CI: 1.41-4.64, I2 = 98%; 1-3 years: OR: 1.47, 95% CI: 1.26-1.71, I2 = 41%; > 3 years: OR: 1.58, 95% CI: 1.16-2.14, I2 = 74%). CONCLUSIONS: PPIs were significantly associated with an increased risk of gastric cancer. However, this association does not confirm causation. Several well-design studies are needed to confirm the findings in the future.

Effects of various treatments for preventing oral mucositis in cancer patients: A network meta-analysis.

BACKGROUND: Oral mucositis (OM) is a common side effect of chemotherapy and radiotherapy in patients with cancers. The prevention or treatment of OM in cancer patients is crucial in the treatment of cancer. METHODS: We searched PubMed, Embase, and Cochrane Library for the randomized control trials (RCTs) of interventions for preventing and treating OM. Network meta-analysis (NMA) was performed to estimate odds ratios (ORs) and 95% confidence intervals (CI) from both direct and indirect evidence. The prespecified primary efficacy outcome was the treatment effect of moderate to severe oral mucositis with 12 interventions. The outcome was moderate to a severe grade of OM. RESULTS: This study included 55 RCTs with 3,552 participants. The results showed that honey significantly lowered the risk of chemo/radiotherapy-induced moderate to severe oral mucositis than placebo (OR: 0.01, 95%CI 0.00 to 0.45), followed by lignocaine (OR: 0.07, 95%CI 0.00 to 0.95). The surface under cumulative ranking curve (SUCRA) values for honey were 0.95, followed by lignocaine (SUCRA, 0.81) and benzydamine (SUCRA, 0.78). CONCLUSIONS: The honey is effective for patients with cancer undergoing chemotherapy or radiotherapy-induced oral mucositis.

Effectiveness of Oil Pulling for Improving Oral Health: A Meta-Analysis.

Objective: The effect of oil pulling on oral health has not yet been fully demonstrated. Therefore, we performed a meta-analysis to investigate the effect of oil pulling on oral health. Methods: We searched PubMed, the Cochrane Library, and the EMBASE database, limiting the search to human patients and articles written in English and published before 31 July 2022. We included randomized controlled trials (RCTs) comparing the effect of oil pulling on improving dental health and oral hygiene. The outcomes of this study were salivary bacteria count, plaque index, and gingival index. Results: In total, nine RCTs were included in this study. The study showed that salivary bacterial colony (BC) counts were significantly reduced in the oil pulling group compared to the control group [mean difference (MD): 17.55, 95% CI 2.56, 32.55]. There was no significant difference between the two groups (MD: -0.10, 95% CI -0.33, 0.14; -0.05, 95% CI -0.12, 0.02) in plaque index and gingival index score. Conclusions: Based on the results of this meta-analysis, the oil pulling may have a beneficial effect on reducing salivary BC count compared to the control group. There was no significant difference in the plaque index and gingival index score between the oil pulling and the control group. Therefore, future clinical trials should be more rigorous and better reported.

Therapeutic efficacy of nivolumab plus sorafenib therapy in patients with unresectable hepatocellular carcinoma.

BACKGROUND: Immune checkpoint inhibitor therapy is the backbone of numerous combination regimens for improving the therapeutic response of patients with hepatocellular carcinoma (HCC). We aimed to investigate the therapeutic efficacy of nivolumab plus sorafenib therapy in patients with unresectable HCC. METHODS: Patients with unresectable HCC who received sorafenib and followed at Taipei Tzu Chi Hospital from January 2016 to May 2022 were selected for this study, and those treated with nivolumab plus sorafenib and those with sorafenib alone were propensity score matched. The primary outcome was overall survival (OS) presented as a hazard ratio calculated using Cox proportional hazards regression models. RESULTS: In the analysis, 36 patients receiving nivolumab plus sorafenib and 36 receiving sorafenib alone were propensity score matched. The median OS for those receiving nivolumab plus sorafenib and sorafenib alone were 3.6 years and 1.2 years, respectively (p = 0.031). The hazard ratio of OS for nivolumab plus sorafenib compared to sorafenib alone was 0.36 (95 %CI, 0.19-0.70; p = 0.003). Furthermore, patients receiving nivolumab plus sorafenib with a baseline α-fetoprotein(AFP) < 10 ng/mL and early reduction in AFP had a 100 % objective response rate and disease control rate. CONCLUSION: In patients with unresectable HCC, nivolumab plus sorafenib resulted in better OS outcomes than sorafenib.

Monoclonal Antibodies for First-Line Treatment Metastatic Colorectal Cancer.

BACKGROUND: In addition to discontinuing treatment at disease progression, cumulative toxicity limitations and genetic mutations play important roles in chemotherapy choice in metastatic colorectal cancer (mCRC). However, in recent years, targeted therapies, such as immune checkpoint inhibitors or monoclonal antibodies (MoAbs), have been used with chemotherapy to improve clinical outcomes in patients with mCRC. AREAS OF UNCERTAINTY: Approximately 15% of patients with CRC would be eligible for further targeted therapy with immune checkpoint inhibitors based on genetic testing, but most patients with CRC would not qualify, especially Kirsten rat sarcoma wild-type. Therefore, adding MoAb is only an option for most patients until disease progression or unacceptable toxicity occurs. However, the results are not consistent with the combination of MoAb and different chemotherapy bases. In addition, most results from combining MoAb with different chemotherapy bases are not consistent. DATA SOURCES: This meta-analysis includes published of the PubMed and Embase databases, limited to English literature, and patients were treated with MoAb combination. Randomized control trials conducted published up to May 2021 were considered for inclusion. THERAPEUTIC ADVANCES: Fluoropyrimidine-based chemotherapy has been the backbone of palliative therapy for mCRC, with demonstrated benefits. This article will review the efficacy and safety of randomized control trials comparing different MoAb with fluoropyrimidine-based chemotherapy as first-line therapy for patients with mCRC, particularly in Kirsten rat sarcoma wild-type. CONCLUSION: This meta-analysis revealed that MoAb plus chemotherapy has better progression-free survival and objective response rate than chemotherapy alone. However, treatment-related serious adverse events (grade ≥ 3) should be considered, particularly severe rash, diarrhea, and hypertension.

Advantages of short-course rifamycin-based regimens for latent tuberculosis infection: an updated network meta-analysis.

OBJECTIVES: We conducted an updated network meta-analysis to elucidate the best regimen for latent tuberculosis infection (LTBI). METHODS: We searched the PubMed, Embase, and Cochrane Library databases on 16 August 2021 to perform an updated network meta-analysis. Only randomised controlled trials on populations with LTBI that reported the efficacy for preventing incident tuberculosis or the completion rates of treatment regimens were included. The Cochrane Collaboration tool was used to assess the risk of bias. We tested for possible global inconsistency with a χ2 test and local inconsistency by calculating inconsistency factors for each comparison in closed loops. The probability of each regimen being at each possible rank was estimated. Comparison-adjusted funnel plots were obtained to assess publication bias, and sensitivity analysis was performed. The major outcomes were the efficacy for preventing incident tuberculosis and the completion rates of treatment regimens. RESULTS: We identified 27 studies that matched our inclusion criteria; the risk of bias was mostly low. Rifampicin for four months (RFMP-4) was the most likely to be effective (probability: 56.3%) and the second most likely treatment to be completed (probability: 22.4%). By applying a multidimensional scaling approach for ranking based on a scatterplot with the surface under the cumulative ranking values for efficacy and completion rates, RFMP-4 was deemed the best choice for treating LTBI. Similar results were demonstrated after sensitivity analysis. CONCLUSION: This updated network meta-analysis revealed RFMP-4 to be the best choice for treating LTBI, per simultaneous consideration of efficacy and completion rates.

Transarterial chemoembolization with or without sorafenib for hepatocellular carcinoma: A real-world propensity score-matched study.

Objectives: Transarterial chemoembolization (TACE) or sorafenib may prolong survival in patients with unresectable hepatocellular carcinoma (HCC); however, whether their combination prolongs survival than TACE alone remains controversial. We aimed to compare the overall survival (OS) of patients with unresectable HCC treated with TACE plus sorafenib (TACE-S) versus TACE alone. Materials and Methods: All patients with unresectable HCC who received TACE as the initial therapy between January 2006 and January 2017 at Taipei Tzu Chi Hospital were enrolled. We matched patients treated with TACE-S and those treated with TACE alone (TACE) by performing propensity score matching at a 1:2 ratio. Our primary outcome was OS during a 10-year follow-up period, and represented as a hazard ratio calculated using Cox proportional hazard regression models. Results: Among 515 patients with unresectable HCC were treated initially with TACE, 56 receiving TACE-S group and 112 receiving TACE alone (TACE group) were included in the primary outcome analysis. The TACE-S group had significantly longer median OS than did the TACE group (1.55 vs. 0.32, years; P < 0.001), and the 5-year OS rates was 10.7% in the TACE-S group and 0.9% in the TACE group (P < 0.001). In multivariate analyses, patients with a lower Child-Pugh score, tumor size ≤5 cm, and no extrahepatic metastasis before treatment and those receiving antiviral agents and receiving TACE-S had longer OS (all P < 0.001). Conclusion: Antiviral agents and the combination of TACE with sorafenib may improve the OS of patients with unresectable HCC.

Efficacy and safety of belimumab therapy in systemic lupus erythematosus: A systematic review and meta-analysis.

BACKGROUND: Belimumab is the first biological agent approved for the treatment of systemic lupus erythematosus (SLE). The efficacy and safety of belimumab for SLE patients are not clear. Therefore, this meta-analysis is integrating the efficacy and safety of belimumab for patients with SLE. METHODS: PubMed, EMBASE, and Cochrane Library were searched for randomized clinical trials (RCTs) that studied the efficacy and safety of belimumab plus standard therapy before November 1, 2021. Data were pooled using the random-effects model and are expressed as risk ratios (RRs) or mean difference (MD) and corresponding 95% confidence intervals (CIs). Heterogeneity was assessed and quantified using I2. RESULTS: Seven RCTs with 3,009 participants were included in this meta-analysis. Belimumab showed significantly decreased at least a 4-point improvement in Safety of Estrogen in Lupus National Assessment (SELENA)-Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score than placebo (RR, 1.32; 95% CI, 1.21-1.44; p < 0.001). However, belimumab significantly reduced the prednisone dose by 50% or more than placebo (RR, 1.59; 95% CI, 1.17-2.15; p = 0.003) and belimumab significantly increased the 36 Physical Component Summary (PCS) score (MD, 1.60; 95% CI, 0.30-2.90; p = 0.02). Regarding adverse events, there was no significant difference between the belimumab group and the control group. CONCLUSION: The results suggest that belimumab plus standard therapy is more effective than placebo plus standard therapy in SLE patients.

Efficacy and immunogenicity of insulin biosimilar compared to their reference products: a systematic review and meta-analysis.

BACKGROUND: To ascertain the efficacy, safety, and immunogenicity from existing evidence via conducting a meta-analysis of randomized controlled trials between biosimilar and originator insulins. METHODS: The PubMed, Cochrane Library, EMBASE, and ClinicalTrails.gov were searched to identify head-to-head randomized controlled trials (RCTs) that directly compare the efficacy and safety of biosimilar insulin and its originator. Efficacy was assessed by change of HbA1C, fasting plasma glucose (laboratory or self-monitoring of blood glucose (SMBG)), and change all mean of 7 points- or 8 points- SMBG. Safety was assessed by change in proportion hypoglycemia and serious hypoglycemia. The occurrence of anti-insulin antibodies (AIAs) was also evaluated. RESULTS: Fourteen RCTs with 6188 patients from different countries were included. Data were pooled using a random-effects model and were expressed as the mean difference (MD), odds ratio (OR), and 95% confidence interval (CI). In efficacy, Insulin biosimilar products showed similar in change of HbA1C at weeks 26 and 52, the MD were 0.03 (95% CI - 0.02 to 0.07, p = 0.28), and 0.05 (95% CI - 0.05 to 0.15, p = 0.36), respectively. The proportion of HbA1C less than 7% at endpoint, the OR were 1.04 (95% CI 0.89 to 1.20, p = 0.64). The change of fasting plasma glucose (laboratory or SMBG) mmol/L in 24-52 weeks and change all mean of 7 points-/8 points- SMBG mmol/L in 24-52 weeks, the MD were 0.02 (95% CI - 0.20 to 0.24, p = 0.87) and - 0.34 (95% CI - 1.35 to 0.67, p = 0.51), respectively. In occurrence of hypoglycemia (≥ 1 events) and severe hypoglycemia, the OR were 0.96 (95% CI 0.85 to 1.09, p = 0.52) and 1.06 (95% CI 0.85 to 1.31, p = 0.62). The AIA was 1.02 (95% CI 0.90 to 1.16, p = 0.76). Analysis stratified by type of diabetes and duration of insulin. There was no significant difference between the biosimilar and their reference group in a different type of diabetes and different duration of insulin. CONCLUSIONS: Insulin biosimilar showed comparable characteristics with the reference drug in terms of efficacy, safety, immunogenicity, through comprehensive and specific conventional meta-analysis.

Refractory systemic capillary leak syndrome treated with bevacizumab: a case report.

Systemic capillary leak syndrome (SCLS) is a syndrome caused by many reasons and without a definitive mechanism. The main diagnostic criteria of SCLS are hemoconcentration, hypoalbuminemia, and hypotension. Though most SCLS improved spontaneously within a few days, it can be life-threatening without effective treatments. In previous literature, vascular endothelial growth factor (VEGF) inhibitor had shown its potential to be an effective treatment, but the treatment outcomes were inconsistent. This article was about a 58-year-old female suffering from refractory systemic capillary leak syndrome after bone marrow transplantation and being treated with bevacizumab, a VEGF inhibitor. In comparison with other successfully treated cases, this patient received four cycles of bevacizumab treatment without symptomatic improvement and eventually died in the intensive care unit. Further studies are needed to further confirm the role of bevacizumab in the management of SCLS.

Immune checkpoint inhibitors for first-line treatment of advanced non-small-cell lung cancer: A systematic review and network meta-analysis.

OBJECTIVE: Currently, several immune checkpoint inhibitors (ICIs) treatment for advanced non-small-cell lung cancer (NSCLC) have been investigated; their overall efficacy and safety remain unclear. METHODS: We searched electronic databases such as PubMed, EMBASE, and the Cochrane library. The randomized controlled trials (RCTs) that compared ICIs with or without chemotherapy to chemotherapy in advanced NSCLC. We collected and compaired thier parameters, including overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and treatment-related adverse events (TRAEs) of grade ≥3. RESULTS: A total of 15 RCTs involving 8869 patients with NSCLC were included. Pembrolizumab plus platinum-based chemotherapy had higher OS and PFS than platinum-based chemotherapy (hazard ratio [HR] 0.55, 95% CI 0.46-0.67; HR 0.54, 95% CI 0.41-0.70, respectively). Pembrolizumab plus platinum-based chemotherapy had higher ranked ORR than platinum-based chemotherapy (odds ratio [OR] 2.92, 95% CI 1.99-4.22). In terms of OS, atezolizumab, pembrolizumab plus platinum-based chemotherapy, and nivolumab plus ipilimumab ranked as the best treatments for patients with programmed death-ligand 1 (PD-L1) expression levels of ≥50%, 1-49%, and <1%, respectively. In terms of PFS, pembrolizumab plus platinum-based chemotherapy ranked as the best treatment for patients with any PD-L1 expression levels. However, ipilimumab plus platinum-based chemotherapy, nivolumab plus platinum-based chemotherapy, and atezolizumab plus platinum-based chemotherapy have higher TRAEs of grade ≥3 than platinum-based chemotherapy. CONCLUSIONS: Pembrolizumab plus platinum-based chemotherapy prevailed in rank in OS, PFS, and ORR benefit. The TRAEs of pembrolizumab plus platinum-based chemotherapy were more than ICI monotherapy and chemotherapy.
