BACKGROUND The A to C transversion in the promoter region of the gene encoding leukotriene C4 synthase (LTC4S) is proposed to be associated with the development of aspirin-induced asthma (AIA). OBJECTIVE We investigated the frequency of the polymorphism in Japanese population and its association with clinical characteristics and cysteinyl leukotriene(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)
7073 Background: Recently several retrospective analyses have reported that somatic activating mutations in the EGFR tyrosine kinase domain underlie responsiveness to gefitinib. In the present study, we have prospectively assessed whether these specific mutations in EGFR gene affect the clinical outcomes of NSCLC pts treated with gefitinib. METHOD Pts(More)
The purpose of this study was to evaluate the efficacy of gefitinib and the feasibility of screening for epidermal growth factor receptor (EGFR) mutations among select patients with advanced non-small cell lung cancer (NSCLC). Stage IIIB/IV NSCLC, chemotherapy-naive patients or patients with recurrences after up to two prior chemotherapy regimens were(More)
BACKGROUND Many patients wish to stay at home during the terminal stage of cancer. However, there is concern that medical care provided at home may negatively affect survival. This study therefore explored whether the survival duration differed between cancer patients who received inpatient care and those who received home care. METHODS We retrospectively(More)
Bradykinin (BK) is a major kinin with well-documented pharmacological properties including vascular leakage and induction of a variety of cytokines. However, the intracellular signalling mechanisms by which BK induced proinflammatory cytokine production have not been fully elucidated. This study investigated the role of the extracellular signal-regulated(More)
The objective of this phase I/II study was to determine the recommended dose (RD) of S-1 and carboplatin (CBDCA), and to evaluate the efficacy and safety of this combination in the treatment of patients with advanced non-small cell lung cancer (NSCLC). Chemotherapy-naïve patients were treated with S-1 given orally on days 1-14, and CBDCA infused(More)
AIMS AND BACKGROUND It is reported that about 20% of patients with small cell lung cancer (SCLC) receive third-line chemotherapy. We conducted a retrospective study to investigate the outcome and prognostic factors of patients with SCLC who receive third-line chemotherapy. METHODS AND STUDY DESIGN The medical records of patients with SCLC who received(More)
BACKGROUND Combined gemcitabine and carboplatin (GC) and combined gemcitabine and vinorelbine (GV) are active and well tolerated chemotherapeutic regimens for patients with advanced nonsmall cell lung cancer (NSCLC). The authors conducted a randomized Phase II study of GC versus GV to compare them in terms of efficacy and toxicity. METHODS One hundred(More)
BACKGROUND Cysteinyl leukotrienes (LTs) and thromboxane A2 (TXA2) are known to play an essential role in the pathogenesis of atopic asthma. However, their role in nonatopic asthma has not as yet been clarified. The objectives of this study were to define (1) the participation of LTs and TXA2 in nonatopic asthma and (2) the relationship between LTs and TXA2(More)
