Lapatinib, a dual tyrosine kinase inhibitor of the epidermal growth factor receptor and human epidermal growth factor receptor 2 (HER2), is clinically active in patients with breast cancer positive for HER2 amplification. The mechanism of this anti-tumor action has remained unclear, however. We have now investigated the effects of lapatinib in HER2(More)
Oxaliplatin is a third-generation platinum compound and a key agent for the management of colorectal cancer. Patients treated with oxaliplatin are at risk for hypersensitivity reactions. We designed a modified premedication regimen to prevent oxaliplatin-related hypersensitivity reactions and assessed if this approach is effective. A retrospective cohort(More)
Extension of metastatic lung tumors into the left atrium via pulmonary veins is rare. Here, we report the first case of Ewing sarcoma exhibiting such extension. A 31-year-old man with pulmonary metastasis from Ewing sarcoma presented with a mass in the left lung, extending to the left atrium through the left inferior pulmonary vein. As the patient was(More)
Background Sunitinib is an oral multitargeted tyrosine kinase inhibitor of vascular endothelial growth factor and platelet-derived growth factor receptors, as well as of other receptor types. We have performed a feasibility study to investigate the safety of sunitinib in combination with pemetrexed for treatment of advanced refractory solid tumors. Methods(More)
BACKGROUND Some of patients with non-small cell lung cancer (NSCLC) harboring somatic activating mutations of the epidermal growth factor receptor gene (EGFR mutations) show poor responses to EGFR-tyrosine kinase inhibitors (EGFR-TKIs) treatment. Cigarette smoking is the strongest documented risk factor for the development of lung cancer. Nicotine, while(More)
e14630 Background: SU is an oral, multitargeted tyrosine kinase inhibitor of VEGFRs, PDGFRs, KIT, RET, FLT3, and CSR-1, and shows antitumor activities in several types of solid malignancies. Non-small-cell lung cancer (NSCLC) xenograft data indicate SU enhanced the antitumor activity of Pem. This phase I study was designed to evaluate the safety,(More)
The purpose of the study was to identify factors that predict unplanned admission for metastatic cancer patients visiting the emergency department (ED). Patients visiting the ED of a general hospital from April 2012 to March 2013 were investigated retrospectively. Data including demographics, vital signs, and laboratory measurements were collected from a(More)
