The aims of this dose-escalating phase I study were to determine the maximum tolerable dose (MTD) and recommended dose (RD) of 5-fluorouracil (5-FU), docetaxel, and nedaplatin (UDON) combination therapy for future phase II studies, and to evaluate the safety and efficacy of this regimen in patients with untreated recurrent or metastatic esophageal cancer.(More)
BACKGROUND The clinical implementation of genomic profiling for lung cancer with high-throughput, multiplex tests is warranted to allow prioritization of appropriate therapies for individual patients. We have now applied such testing to detect actionable mutations that may inform treatment recommendations in lung cancer. PATIENTS AND METHODS We(More)
Background The efficacy of programmed death-1 blockade in epidermal growth factor receptor gene (EGFR) mutation-positive non-small-cell lung cancer (NSCLC) patients with different mechanisms of acquired resistance to EGFR tyrosine kinase inhibitors (TKIs) is unknown. We retrospectively evaluated nivolumab efficacy and immune-related factors in such patients(More)
BACKGROUND Patients with metastatic colorectal cancer (mCRC) harboring wild-type KRAS benefit from epidermal growth factor receptor (EGFR)-targeted therapy. However, patients who are treated with anti-EGFR antibodies will eventually develop the resistance to those agents. HER2 amplification is one of the mechanisms conferring resistance to anti-EGFR(More)
BACKGROUND We evaluated the safety, maximum-tolerated dose (MTD), pharmacokinetics, recommended dose for phase II (P2RD), and preliminary anticancer activity of a combination eribulin and S-1 therapeutic in metastatic breast cancer patients pretreated with anthracycline and taxane. METHOD Patients aged 20-74 years were recruited. In level 1, patients(More)
BACKGROUND Overexpression of heregulin, a HER3 ligand, is one mechanism that confers resistance to the anti-HER2 agents trastuzumab and lapatinib. We investigated the impact of heregulin expression on the efficacy of HER2-targeted therapeutic agents, including trastuzumab, trastuzumab emtansine (T-DM1) and lapatinib, in vitro and in vivo and evaluated the(More)
Both afatinib and erlotinib are tyrosine kinase inhibitors that inhibit aberrant epidermal growth factor receptor (EGFR) signals in non-small-cell lung cancer (NSCLC). Afatinib is an irreversible inhibitor directed against EGFR, ErbB-2, and ErbB-4, whereas erlotinib is a reversible inhibitor directed against EGFR only. Although afatinib has been shown to be(More)
Anti-HER2 therapies are beneficial for patients with HER2-positive breast or gastric cancer. T-DM1 is a HER2-targeting antibody-drug conjugate (ADC) comprising the antibody trastuzumab, a linker, and the tubulin inhibitor DM1. Although effective in treating advanced breast cancer, all patients eventually develop T-DM1 resistance. DS-8201a is a new ADC(More)
