The Impact of Afatinib on Survival in Advanced Non-Small Cell Lung Cancer: A Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Background: Afatinib is a second-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) that has been approved by the Food and Drug Administration for the treatment of advanced non-small cell lung cancer (NSCLC) harboring EGFR mutations. We performed a meta-analysis to assess the efficacy and safety of afatinib in advanced NSCLC. Methods: We searched PubMed, PMC database, EMBASE, Cochrane Library and Web of Science to obtain the relevant literature. The efficacy and safety of afatinib was assessed based on progression-free survival (PFS), overall survival (OS), overall response rate (ORR), primary grade 3/4 adverse events and fatal adverse events (FAEs). A subgroup analysis was performed according to control type for all end-points. Results: Seven randomized controlled trials were included, with a total of 3093 patients. The meta-analysis showed that afatinib treatment significantly prolonged PFS in patients compared with control groups (HR = 0.57, 95% CI: 0.42-0.76; P = 0.00), increased OS (HR = 0.91, 95% CI: 0.83-0.99; P = 0.04) and ORR (RR = 1.82, 95% CI: 1.13-2.93; P = 0.01). In terms of safety, afatinib significantly increased the incidence of diarrhea (RR = 8.9, 95% CI: 5.33-14.93; P = 0.00), rash (RR = 7.31, 95% CI: 1.56-34.12; P = 0.01) and stomatitis (RR = 6.45, 95% CI: 1.27-32.78; P = 0.03), compared with the control group. However, there was no significant difference in FAEs (RR = 0.75, 95% CI: 0.38-1.49; P = 0.41). Conclusions: This meta-analysis confirmed that afatinib extended survival, improved response rates and did not increase the risk of treatment-related mortality in advanced NSCLC. As a novel EGFR-TKI, afitinib has significant potential for clinical application.

Project description:Background: This meta-analysis aimed to explore if immunotherapy or chemotherapy alone or in combination is a better first line treatment strategy for advanced non-small cell lung cancer (NSCLC) patients. Methods: Electronic databases including Google Scholar, PMC, PubMed, EMBASE, Scopus and the major conference proceedings were searched for relevant randomized controlled trials (RCTs) comparing outcomes of immune-checkpoint inhibitor combined with chemotherapy or immune-checkpoint inhibitor alone over chemotherapy alone in patients with advanced NSCLC without previous treatment. Study heterogeneity was assessed using the I2 test. Results: A total of 14 RCTs including 8,081 treatment naïve advanced NSCLC patients were enrolled in this study. Our results showed that in comparison to chemotherapy alone, introducing immunotherapy into first-line chemotherapy has significant benefit in tumor response (RR, 1.27; 95% CI, 1.09 to 1.48), progression-free survival (PFS) (HR, -0.43; 95% CI, -0.56 to -0.31), and overall survival (OS) (HR, -0.30; 95% CI, -0.45 to -0.14) but with an increased risk of grade3 - 5 toxicity (RR, 1.11; 95% CI, 1.04 to 1.18). The pooled results of comparison of immune therapy alone with chemotherapy alone in selected patients with positive expression of Programmed Death-ligament (PD-L1) or with a high tumor mutational burden, demonstrated similar tumor response (RR, 1.13; 95% CI, 0.88 to 1.46), 3 - 5 grade toxicity (RR, 0.69; 95% CI, 0.40 to 1.19) and long-term outcomes, including OS (HR, -0.20; 95% CI, -0.43 to 0.03) and PFS (HR, -0.24; 95% CI, -0.61 to 0.14). Conclusions: Our meta-analysis showed the superiority of combination therapy over monotherapy with chemotherapeutic agents in terms of tumor response, and long-term survival, but with an increased the 3 - 5 grade toxicity. And immune-checkpoint inhibitors alone showed similar tumor response, toxicity and long-term outcomes compared to platinum-based chemotherapy in selected patients.
