Co-clinical trials demonstrate superiority of crizotinib to chemotherapy in ALK-rearranged non-small cell lung cancer and predict strategies to overcome resistance.
In this study, we evaluated the performance of a novel assay called ADx-SuperARMS in detecting EGFR mutations in plasma cell-free DNA from patients with advanced lung adenocarcinoma.
Compared with chemotherapy, use of the 1st generation of EGFR-TKIs as first-line therapy can improve the short-term efficacy of patients with EGFR uncommon mutations advanced lung adenocarcinoma, but platinum-based chemotherapy showed a longer overall survival.
The presence of EGFR mutations is a major determinant of gefitinib response, and EGFR tyrosine kinase inhibitors should be tested in clinical trials of first-line treatment of lung adenocarcinomas harboring EGFR mutations.
Activity of pemetrexed and high-dose gefitinib in an EGFR-mutated lung adenocarcinoma with brain and leptomeningeal metastasis after response to gefitinib.
Only the invasive AC presented epidermal growth factor receptor (EGFR) mutation, while anaplastic lymphoma kinase (ALK) rearrangement was detected in none of them.
In this study, we optimized magnetic- and fluorescence-based isolation protocols to segregate lung epithelial (CD326/epithelial cell adhesion molecule-positive), endothelial (CD31-positive), and immune (CD45-positive) cells, with high purity, from the lungs of transgenic mice with mutant epidermal growth factor receptor-induced lung adenocarcinomas.
This study aimed to detect EGFR gene mutations using next-generation sequencing (NGS) from different types of body fluids from patients with lung adenocarcinoma.
Re-biopsy and large panel NGS revealed an EGFR mutant lung adenocarcinoma with alternating changes in acquired resistance between EGFR and ALK.The total survival time was 73 months.
Frozen tissues of lung adenocarcinoma and corresponding normal lung were obtained from 341 patients, including 141 with tumors harboring driver gene alterations (50 EGFR gene mutations, 50 KRAS gene mutations, 21 ALK fusions, 10 ROS1 fusions, and 10 RET fusions) and 200 with pan-negative tumors (100 never- or light-smokers and 100 heavy-smokers), who were surgically treated between 2007 and 2015.
In this series, 230 resected lung adenocarcinomas from smoker (>100 cigarettes in lifetime) at single center (Shanghai Cancer Center, Shanghai, China) were tested for mutation in EGFR, KRAS, BRAF, HER2, EML4-ALK and PIK3CA.
The studies, phase III study of afatinib or cisplatin plus pemetrexed in patients with metastatic lung adenocarcinoma with EGFR mutations (LUX-Lung 3) and a randomized, open-label, phase III study of BIBW 2992 versus chemotherapy as first-line treatment for patients with stage IIIB or IV adenocarcinoma of the lung harbouring an EGFR activating mutation (LUX-Lung 6) investigated first-line afatinib versus platinum-based chemotherapy in epidermal growth factor receptor gene (EGFR) mutation-positive patients with NSCLC and included patients with brain metastases; prespecified subgroup analyses are assessed in this article.
With the discoveries of many actionable driver mutations such as activating EGFR mutations and ALK rearrangement in adenocarcinoma of the lung we have switched to classifying non-small cell lung cancer into different individual molecular subgroups based on the presence of a dominant driver mutation.
Therefore, this prospective study examined whether EGFR single nucleotide polymorphisms (SNPs) are associated with different survival time in advanced lung adenocarcinoma patients treated with Gefitinib.
In this surgical series, 52 resected lung adenocarcinomas from never-smokers (< 100 cigarettes in a lifetime) at a single institution (Fudan University, Shanghai, China) were analyzed concurrently for mutations in EGFR, KRAS, NRAS, HRAS, HER2, BRAF, ALK, PIK3CA, TP53 and LKB1.
