BACKGROUND The survival benefit and morbidity after nodal dissection for gastric cancer remains controversial. We aimed to do a single-institution randomised trial to compare D1 (ie, level 1) lymphadenectomy with that of D3 (ie, levels 1, 2, and 3) dissection for gastric cancer in terms of overall survival and disease-free survival. METHODS From Oct 7,(More)
Apurinic/apyrimidinic endonuclease 1 (APE1) is an essential enzyme in the base excision repair pathway, which is the primary mechanism for the repair of DNA damage caused by oxidation and alkylation. We hypothesized that polymorphisms of APE1 are associated with risk for lung cancer. In the hospital-based matched case-control study, a total of 730 lung(More)
PURPOSE SOX9 is an important transcription factor required for development and has been implicated in several types of cancer. However, SOX9 has never been linked to lung cancer to date. Here, we show that SOX9 expression is upregulated in lung adenocarcinoma and show how it is associated with cancer cell growth. EXPERIMENTAL DESIGN Data mining with five(More)
OBJECTIVE Oncogenic human papillomavirus (HPV) is the cause of cervical cancer. Hypermethylation of the CpG islands located at the long control region (LCR) of the HPV genome may regulate the expression of the major oncogenes E6 and E7, and may relate to cancer progression. The goal of the present study was to investigate the methylation patterns of CpG(More)
Genome-wide association studies of lung cancer reported in populations of European background have identified three regions on chromosomes 5p15.33, 6p21.33, and 15q25 that have achieved genome-wide significance with p-values of 10(-7) or lower. These studies have been performed primarily in cigarette smokers, raising the possibility that the observed(More)
We valuated specific cellular and humoral immune response of cases of enterovirus 71 (EV71) infection and correlated immune response with clinical outcome. After obtaining informed consent, we enrolled 30 EV71 cases including 7 cases with brainstem encephalitis plus pulmonary edema, 12 cases of CNS (CNS) involvement and 11 uncomplicated cases. We measured(More)
To identify common genetic variants that contribute to lung cancer susceptibility, we conducted a multistage genome-wide association study of lung cancer in Asian women who never smoked. We scanned 5,510 never-smoking female lung cancer cases and 4,544 controls drawn from 14 studies from mainland China, South Korea, Japan, Singapore, Taiwan and Hong Kong.(More)
Simulation tools that simulate sequence data in unrelated cases and controls or in families with quantitative traits or disease status are important for genetic studies. The simulation tools can be used to evaluate the statistical power for detecting the causal variants when planning a genetic epidemiology study, or to evaluate the statistical properties(More)
Reactivation of hepatitis is one of the most serious complications of chemotherapy in lymphoma patients who are carriers of the hepatitis B virus (HBV). Glucocorticoids are linked to increased risk of HBV reactivation. This study seeks to clarify whether removal of glucocorticoids from chemotherapy regimens may decrease the risk of HBV reactivation.(More)
Resting heart rate is significantly associated with cardiovascular morbidity and mortality. However, the extent to which resting heart rate is genetically determined is poorly understood, and no genes have been found that contribute to variation in resting heart rate. Because signaling through the beta1 adrenergic receptor is a key determinant of cardiac(More)
