BACKGROUND In single-group studies, chromosomal rearrangements of the anaplastic lymphoma kinase gene (ALK) have been associated with marked clinical responses to crizotinib, an oral tyrosine kinase inhibitor targeting ALK. Whether crizotinib is superior to standard chemotherapy with respect to efficacy is unknown. METHODS We conducted a phase 3,(More)
BACKGROUND Despite recent advances in the treatment of advanced non-small-cell lung cancer, there remains a need for effective treatments for progressive disease. We assessed the efficacy of pembrolizumab for patients with previously treated, PD-L1-positive, advanced non-small-cell lung cancer. METHODS We did this randomised, open-label, phase 2/3 study(More)
BACKGROUND The EGFR T790M mutation is the most common mechanism of drug resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in patients who have lung cancer with an EGFR mutation (EGFR-mutated lung cancer). In preclinical models, the EGFR inhibitor AZD9291 has been shown to be effective against both EGFR tyrosine kinase(More)
The excision repair cross-complementation group 1 (ERCC1) enzyme plays a rate-limiting role in the nucleotide excision repair pathway and is associated with resistance to platinum-based chemotherapy. The purpose of this study was to evaluate the role of ERCC1 expression as a predictive marker of survival in patients with locally advanced squamous cell(More)
PURPOSE To determine the efficacy of consolidation chemotherapy (CC) with docetaxel and cisplatin (DP) after concurrent chemoradiotherapy (CCRT) with the same agents in locally advanced non-small-cell lung cancer (LA-NSCLC). PATIENT AND METHODS Patients were randomly assigned to either CCRT alone (observation arm) or CCRT followed by CC (consolidation(More)
PURPOSE The ISTANA (IRESSA as Second-line Therapy in Advanced NSCLC-KoreA) study compared gefitinib with docetaxel in patients with advanced or metastatic non-small cell lung carcinoma (NSCLC) pretreated with platinum-based chemotherapy. EXPERIMENTAL DESIGN We conducted a multicenter, randomized, open-label phase III trial of gefitinib (250 mg/d) versus(More)
PURPOSE To evaluate the feasibility and safety of repeat biopsy for mutational analysis in patients with non-small cell lung cancer (NSCLC) who have a resistance history to previous chemotherapy. MATERIALS AND METHODS This prospective study was institutional review board approved, and written informed consent was obtained from all patients. Of 126(More)
PURPOSE Phase I data (ASCEND-1) showed ceritinib efficacy in patients with ALK-rearranged non-small-cell lung cancer (NSCLC), regardless of brain metastases status and with or without prior therapy with an inhibitor of the ALK protein. Data are presented from a phase II trial (ASCEND-2) in which ceritinib efficacy and safety were evaluated in patients who(More)
BACKGROUND Skeletal-related events (SREs) cause significant pain and morbidity to many non-small cell lung cancer (NSCLC) patients. We try to evaluate the predictive factor of SREs in NSCLC patients with bone metastases. PATIENTS AND METHODS We retrospectively examined the medical charts of 273 patients diagnosed with bone metastases secondary to NSCLC.(More)
BACKGROUND We assessed the efficacy and safety of programmed cell death 1 (PD-1) inhibition with pembrolizumab in patients with advanced non-small-cell lung cancer enrolled in a phase 1 study. We also sought to define and validate an expression level of the PD-1 ligand 1 (PD-L1) that is associated with the likelihood of clinical benefit. METHODS We(More)
