RESUMEN
BRAF gene mutation is found in about 2%-4% of the patients with non-small cell lung cancer (NSCLC). This type of NSCLC is characterized by high malignancy, low efficacy of chemotherapy and poor prognosis. Although the combination treatment of BRAF inhibitor and MEK inhibitor has achieved remarkable results in advanced NSCLC patients with BRAF V600E mutation, which has been written into the National Comprehensive Cancer Network (NCCN) guidelines, severe side effects of the combination therapy are frequently observed. There isn't effective treatment strategy after drug resistance, and targeted therapy for non-V600E mutation patients is still lacking. In this paper, we summarized the researches on expression of immune markers in NSCLC patients with mutant BRAF and analyzed the studies on efficacy of immune checkpoint inhibitor (ICI), so as to provide more options for prolonging survival of the patients. .
RESUMEN
Targeted therapy is one of the major treatment modalities in advanced non-small cell lung cancer (NSCLC) with sensitive driver gene mutations. BRAF is considered a promising oncogenic driver in NSCLC after the discovery of epidermal growth factor receptor (EGFR) mutation, anaplastic lymphoma kinase (ALK) fusion and ROS1 rearrangement. BRAF V600E mutation accounts for more than half of BRAF mutations, which is a potential therapeutic target for advanced NSCLC. This review aims to summarize the advancements of BRAF gene mutation and targeted therapy for BRAF mutation in NSCLC. .
