[Effects of EGFR gene polymorphisms on efficacy and prognosis in advanced non-small cell lung cancer treated with EGFR-TKIs].

ABSTRACT: An increasing number of patients with advanced non-small cell lung cancer (NSCLC) have been treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). However, significant differences in response to EGFR-TKIs have been shown among advanced NSCLC patients. Recently, selection of patients was mainly based on EGFR gene mutation detection. Nevertheless, mutation detection is often limited by tumour tissues derivation, technique complexity, high cost, and so on. It is urgent to seek other biological markers to predict efficacy of EGFR-TKIs. Many studies have founded that the EGFR gene polymorphisms are also associated with clinical outcome and prognosis in treatment of advanced NSCLC with EGFR-TKIs. Here, we presented a review discussing the correlation between EGFR gene polymorphisms and the efficacy of EGFR-TKIs in advanced NSCLC.

Project description:BackgroundWhile prospective clinical studies on immunotherapy in epidermal growth factor receptor (EGFR) mutant non-small-cell lung cancer (NSCLC) with acquired resistance to EGFR tyrosine kinase inhibitors (TKIs) are ongoing, this study aimed to investigate the outcomes of immunotherapy combinations in such a population in a real-world setting.MethodsThe clinical data of pretreated EGFR-mutated NSCLC patients who acquired EGFR-TKI resistance and received immunotherapy were retrospectively analyzed in this study. Progression-free survival (PFS) was assessed using the Kaplan-Meier log-rank test, and univariate and multivariate analysis were performed.ResultsA total of 31 patients were analyzed in this study. A total of 25 (80.6%) patients received combination immunotherapy. In the univariate analysis, patients who received combination immunotherapy seemingly acquired longer PFS than those who received monotherapy, although there was no significant difference (3.42 months vs. 1.61; P = 0.078; hazard ratio (HR) 0.43, 95% CI: 0.16-1.13). Patients who received antiangiogenic drugs prior to immunotherapy acquired better PFS (3.42 months vs. 1.58; P = 0.027; HR 0.37, 95% CI: 0.15-0.93), while patients with liver metastasis had inferior PFS (2.04 months vs. 3.42; P = 0.031; HR 2.83, 95% CI: 1.05-7.60). Furthermore, multivariate analysis confirmed that the above three factors had independent prognostic value.ConclusionsThe study revealed that immunotherapy combinations are better choices than single-agent regimens in previously treated and EGFR-mutant NSCLC patients with progressive disease. In addition, antiangiogenic drugs administered before immunotherapy might be a favorable prognostic factor, while liver metastasis was associated with a short PFS in this setting. In future, more robust and prospective clinical trial results are expected to guide clinical practice.Key pointsSignificant study findings Immunotherapy-based combination therapies are better choices than single-agent regimens in heavily treated EGFR-mutant NSCLC patients. What this study adds Patients without liver metastasis and with prior antiangiogenic drugs obtained more benefit from immunotherapy in this setting.
