BACKGROUND Patients with non-small-cell lung cancer harbouring mutations in the epidermal growth factor receptor (EGFR) gene respond well to the EGFR-specific tyrosine kinase inhibitor gefitinib. However, whether gefitinib is better than standard platinum doublet chemotherapy in patients selected by EGFR mutation is uncertain. METHODS We did an open(More)
PURPOSE The primary goal of this open-label, multicenter, randomized phase III trial was to determine whether treatment with carboplatin plus the oral fluoropyrimidine derivative S-1 was noninferior versus that with carboplatin plus paclitaxel with regard to overall survival (OS) in chemotherapy-naive patients with advanced non-small-cell lung cancer(More)
PURPOSE To establish dosimetric predictors of radiation esophagitis (RE) in patients treated with a combination of carboplatin, paclitaxel, and radiotherapy. METHODS AND MATERIALS Three-dimensional radiotherapy plans of 26 patients with non-small-cell lung cancer who received 50-60 Gy of radiotherapy concurrently with weekly administration of carboplatin(More)
PURPOSE Gefitinib is a small molecule inhibitor of the epidermal growth factor receptor tyrosine kinase. We conducted a phase III trial to evaluate whether gefitinib improves survival as sequential therapy after platinum-doublet chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Chemotherapy-naïve patients with(More)
BACKGROUND RET rearrangements are rare oncogenic alterations in non-small-cell lung cancer (NSCLC). Vandetanib is a multitargeted tyrosine kinase inhibitor exhibiting RET kinase activity. We aimed to assess the efficacy and safety of vandetanib in patients with advanced RET-rearranged NSCLC. METHODS In this open-label, multicentre, phase 2 trial (LURET),(More)
BACKGROUND Osimertinib (AZD9291) is an oral, potent, irreversible EGFR tyrosine-kinase inhibitor selective for EGFR tyrosine-kinase inhibitor sensitising mutations, and the EGFR Thr790Met resistance mutation. We assessed the efficacy and safety of osimertinib in patients with EGFR Thr790Met-positive non-small-cell lung cancer (NSCLC), who had progressed(More)
PURPOSE The epidermal growth factor receptor (EGFR) tyrosine kinase has been an important target for non-small-cell lung cancer. Several EGFR tyrosine kinase inhibitors (TKIs) are currently approved, and both gefitinib and erlotinib are the most well-known first-generation EGFR-TKIs. This randomized phase III study was conducted to investigate the(More)
PURPOSE This randomized phase III trial was conducted to confirm noninferiority of amrubicin plus cisplatin (AP) compared with irinotecan plus cisplatin (IP) in terms of overall survival (OS) in chemotherapy-naive patients with extensive-disease (ED) small-cell lung cancer (SCLC). PATIENTS AND METHODS Chemotherapy-naive patients with ED-SCLC were randomly(More)
PURPOSE To clarify whether the percentage of pulmonary volume irradiated to >20 Gy (V20) is related to the incidence and grade of radiation pneumonitis (RP) in cases of lung cancer treated with concurrent chemoradiation. METHODS AND MATERIALS The subjects comprised 71 patients with lung cancer who were treated with conventionally fractionated definitive(More)
BACKGROUND Epidermal growth factor receptor (EGFR) mutation is predictive for the efficacy of EGFR tyrosine kinase inhibitors in advanced non-small-cell lung cancer (NSCLC) treatment. We evaluated the performance, sensitivity, and concordance between five EGFR tests. MATERIALS AND METHODS DNA admixtures (n = 34; 1%-50% mutant plasmid DNA) and samples from(More)
