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 To compare fluorouracil (FU) alone with FU plus cisplatin (FP) and with uracil and tegafur plus mitomycin (UFTM) for patients with advanced gastric cancer in a prospective, randomized, controlled trial. PATIENTS AND METHODS A total of 280 patients with advanced gastric cancer were randomly allocated and analyzed for survival, response, and(More)
The purpose of this study was to evaluate the usefulness of the Neonatal Behavioral Assessment Scale (NBAS) as a tool to assess the risk of later developmental disabilities. The study subjects were 209 low birth-weight and/or premature infants admitted to the NICU at the Nagasaki University Hospital, Nagasaki, Japan. These infants were examined using the(More)
BACKGROUND The best chemotherapy regimen for metastatic gastric cancer is uncertain, but promising findings have been reported with irinotecan plus cisplatin and S-1 (tegafur, 5-chloro-2,4-dihydropyrimidine, and potassium oxonate). We aimed to investigate the superiority of irinotecan plus cisplatin and non-inferiority of S-1 compared with fluorouracil,(More)
In flowering plants, the male gametophyte, the pollen, develops in the anther. Complex patterns of gene expression in both the gametophytic and sporophytic tissues of the anther regulate this process. The gene expression profiles of the microspore/pollen and the sporophytic tapetum are of particular interest. In this study, a microarray technique combined(More)
A longitudinal study was performed to investigate the associations of exposure to environmental cadmium (Cd) with cause-specific mortality and cancer incidence rates. The study population comprised 275 adults living in a Cd-polluted area, Nagasaki Prefecture, Japan. The follow-up period extended from 1982 to 2005 for the analysis of cancer mortality, and(More)
The association between exposure to environmental cadmium and mortality was investigated in two cohorts. The study population consisted of 275 (cohort I) and 329 (cohort II) residents (aged >or=40 years) in a cadmium-polluted area, Nagasaki Prefecture, Japan, who had participated in health surveys conducted in 1982 and 1992, respectively. The follow-up(More)
BACKGROUND Gastric cancer is the leading cause of death from cancer in Japan. In 2004, there were 50 562 deaths from gastric cancer; they accounted for 15.8% of the total number of cancer deaths. Since 1983, under the Health Service Law for the Aged, gastric cancer screening has been conducted nationwide for all residents aged 40 years and over. METHODS(More)
This study evaluated the antitumor effect and safety of S-1, an oral fluoropyrimidine derivative, in patients with metastatic pancreatic cancer. Chemo-naive patients with pancreatic adenocarcinoma, and measurable metastatic lesions were enrolled. S-1 was administered orally twice daily after meals at a dose of 80, 100, or 120 mg/day for body surface areas(More)
