Efficacy and safety of immune checkpoint inhibitors versus chemotherapy in the second-line treatment of advanced esophageal squamous cell carcinoma: a meta-analysis and systematic review.

ABSTRACT:

Background

Esophageal cancer (EC) is the seventh most common cancer in the world, with 604,000 new cases diagnosed each year. Immune checkpoint inhibitors (ICIs) including programmed death ligand-1 (PD-L1) inhibitors have demonstrated a considerable survival advantage over chemotherapy in numerous randomized controlled trials (RCTs), particularly in patients with advanced esophageal squamous cell carcinoma (ESCC). In this analysis, we aimed to demonstrate that ICIs are more safe and effective than chemotherapy when used as a second-line treatment for advanced ESCC.

Methods

Publications on the safety and efficiency of ICIs in advanced ESCC that were available prior to February 2022 were searched in the Cochrane Library, Embase, and PubMed databases. Studies with missing data were eliminated, and studies that compared the treatments between the immunotherapy group and chemotherapy group were included. Statistical analysis was carried out using RevMan 5.3, and risk and quality were evaluated with relevant evaluation tools.

Results

Five studies met the inclusion criteria were selected, involving 1,970 patients with advanced ESCC. We compared chemotherapy and immunotherapy in the second-line treatment of advanced ESCC. ICIs considerably enhanced both the objective response rate (P=0.007) and overall survival (OS; P=0.001). However, the effect of ICIs on progression-free survival (PFS) was not significant (P=0.43). ICIs presented fewer grade 3-5 treatment-related adverse events (TRAEs), and there was also a suggested linkage between both PD-L1 expression and the effectiveness of the therapeutic intervention.

Conclusions

For patients with advanced ESCC, ICIs are more effective and safer than chemotherapy, and thus have a higher treatment value.

Project description:BackgroundRecently, several novel programmed cell death protein 1 (PD-1) inhibitors have been approved for second-line treating advanced or metastatic oesophageal squamous cell carcinoma (OSCC), including camrelizumab, nivolumab, pembrolizumab, sintilimab and tislelizumab. However, the optimal treatment regimen remained ambiguous.ObjectivesThe purpose of this study was to investigate the efficacy, safety and economy of available PD-1 inhibitors to determine the optimal treatment from the Chinese healthcare system perspective.DesignA systematic review and economic evaluation.Data sources and methodsA systematic review was undertaken utilizing PubMed, Web of Science, Cochrane Library, Embase and Scopus databases to identify eligible studies until 31 August 2023. Primary outcomes were progression-free survival (PFS), overall survival (OS) and adverse events (AEs). We also developed a partitioned survival model at 3-week intervals based on five clinical trials to predict long-term costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios for various treatment options. Direct medical costs and utility values were obtained from public drug bidding databases, clinical trials or published literature. The parameter uncertainties within the model were determined via one-way and probabilistic sensitivity analyses.ResultsFive randomized controlled trials involving 2837 patients were included in the analysis. Compared with other treatments examined, camrelizumab provided the best PFS benefits [hazard ratio (HR): 0.69, 95% confidence interval (CI): 0.56-0.86], and pembrolizumab provided the best OS benefits (HR: 0.55, 95% CI: 0.37-0.82). Nivolumab caused a relatively lower incidence of treatment-related AEs (HR: 0.10, 95% CI: 0.05-0.20) and grade 3-5 AEs (HR: 0.13, 95% CI: 0.08-0.21) than other immunotherapy regimens. In the economic evaluation, average 10-year costs ranged from $5,433.86 (chemotherapy) to $50,617.95 (nivolumab) and mean QALYs ranged from 0.55 (chemotherapy) to 0.82 (camrelizumab). Pembrolizumab was eliminated because of dominance. Of the remaining strategies, when the willingness-to-pay thresholds were 1, 2 and 3 times GDP per capita in 2022, sintilimab, tislelizumab and camrelizumab were the most cost-effective treatment options, respectively.ConclusionSintilimab might be the optimal treatment alternative for second-line therapy of advanced OSCC in China, followed by tislelizumab and camrelizumab.Trial registrationThis study has been registered on the PROSPERO database with the registration number CRD42023495204.

Project description:PurposePatients with advanced or metastatic esophageal squamous cell carcinoma (ESCC) have poor prognosis. For these patients, treatment options are limited after first-line systemic therapy.Patients and methodsIn this open-label phase III clinical study, patients with advanced or metastatic ESCC, whose tumor progressed after first-line systemic treatment, were randomly assigned (1:1) to receive intravenous tislelizumab, an anti-programmed cell death protein 1 antibody, 200 mg every 3 weeks or chemotherapy (investigator's choice of paclitaxel, docetaxel, or irinotecan). The primary end point was overall survival (OS) in all patients. The key secondary end point was OS in patients with programmed death-ligand 1 tumor area positivity (TAP) score ≥ 10%.ResultsIn total, 512 patients across 11 countries/regions were randomly assigned. At final analysis, conducted after 410 death events occurred, OS was significantly longer with tislelizumab versus chemotherapy in all patients (median, 8.6 v 6.3 months; hazard ratio [HR], 0.70 [95% CI, 0.57 to 0.85]; one-sided P = .0001), and in patients with TAP ≥ 10% (median, 10.3 months v 6.8 months; HR, 0.54 [95% CI, 0.36 to 0.79]; one-sided P = .0006). Survival benefit was consistently observed across all predefined subgroups, including those defined by baseline TAP score, region, and race. Treatment with tislelizumab was associated with higher objective response rate (20.3% v 9.8%) and a more durable antitumor response (median, 7.1 months v 4.0 months) versus chemotherapy in all patients. Fewer patients experienced ≥ grade 3 treatment-related adverse events (18.8% v 55.8%) with tislelizumab versus chemotherapy.ConclusionTislelizumab significantly improved OS compared with chemotherapy as second-line therapy in patients with advanced or metastatic ESCC, with a tolerable safety profile. Patients with programmed death-ligand 1 TAP ≥ 10% also demonstrated statistically significant survival benefit with tislelizumab versus chemotherapy.

Project description:BackgroundThis study aims to evaluate the efficacy and safety of camrelizumab in combination with chemotherapy as a second-line treatment for patients with locally advanced, recurrent, or metastatic esophageal squamous cell carcinoma (ESCC).MethodsIn this retrospective, single-center observational study, we collected medical records of patients with locally advanced, recurrent, or metastatic ESCC who received either camrelizumab combined with chemotherapy or chemotherapy alone as second-line treatment between July 1, 2019, and May 31, 2023. We evaluated short-term efficacy, including overall response rate (ORR) and disease control rate (DCR), as well as survival outcomes, including progression-free survival (PFS) and overall survival (OS). Safety was also assessed. Additionally, factors influencing OS in ESCC patients were analyzed.ResultsA total of 60 patients with locally advanced, recurrent, or metastatic ESCC were included, with 30 receiving camrelizumab combined with chemotherapy and 30 receiving chemotherapy alone as second-line treatment. There were no statistically significant differences in ORR (33.33% vs. 13.33%) and DCR (73.33% vs. 56.67%) between the combination therapy and chemotherapy-alone groups (P > 0.05). However, the median PFS was significantly longer in the combination therapy group compared to the chemotherapy group (4.7 months vs. 3.4 months, P = 0.048). Additionally, the median OS was significantly improved in the combination therapy group compared to the chemotherapy group (11.7 months vs. 6.5 months, P = 0.003). Age and history of radical surgery were significantly associated with OS in patients receiving camrelizumab combined with chemotherapy as second-line treatment (P < 0.05).ConclusionSecond-line treatment with camrelizumab combined with chemotherapy is well-tolerated and associated with favorable oncological outcomes in patients with locally advanced, recurrent, or metastatic ESCC. Furthermore, younger patients and those who have undergone radical surgery may derive greater benefit from camrelizumab combined with chemotherapy as a second-line treatment.

Project description:BackgroundRATIONALE 302 (NCT03430843) an open-label, phase III study of second-line treatment of advanced/metastatic esophageal squamous cell carcinoma (ESCC), reported that tislelizumab, relative to investigator-chosen chemotherapy (ICC), was associated with improvements in overall survival and a favorable safety profile. This study assessed the health-related quality of life (HRQoL) and ESCC-related symptoms of patients in RATIONALE 302.MethodsAdults with advanced/metastatic ESCC whose disease progressed following prior systemic therapy were randomized 1 : 1 to receive either tislelizumab or ICC (paclitaxel, docetaxel, or irinotecan). HRQoL was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 items (EORTC QLQ-C30), the EORTC Quality of Life Questionnaire Oesophageal Cancer Module 18 items (QLQ-OES18), and the EuroQoL Five-Dimensions Five-Levels (EQ-5D-5L) visual analogue scale. Mixed effect modeling for repeated measurements examined changes from baseline to weeks 12 and 18. The Kaplan-Meier method was used to examine time to deterioration.ResultsOverall, 512 patients were randomized to tislelizumab (n = 256) or ICC (n = 256). The tislelizumab arm maintained QLQ-C30 global health status/quality whereas the ICC arm worsened at week 12 {difference in least square (LS) mean change: 5.8 [95% confidence interval (CI): 2.0-9.5], P = 0.0028} and week 18 [difference in LS mean change: 8.1 (95% CI: 3.4-12.8), P = 0.0008]. Physical functioning (week 18) and fatigue (weeks 12 and 18) worsened less in the tislelizumab compared with the ICC arm. The tislelizumab arm improved in reflux symptoms, whereas the ICC worsened at week 12 [difference in LS mean change: -4.1 (95% CI: -7.6 to -0.6), P = 0.0229]. The visual analogue scale remained consistent in the tislelizumab arm whereas it worsened in the ICC arm. The hazard of time to deterioration was lower in tislelizumab patients compared with ICC for physical functioning and reflux.ConclusionsHRQoL, including fatigue symptoms and physical functioning, was maintained in patients with advanced or metastatic ESCC receiving tislelizumab compared with ICC-treated patients. These results provide additional support for the benefits of tislelizumab in this patient population.
