BACKGROUND Platelets have been reported to act as transporters of tumor-originated vascular endothelial growth factor (VEGF), contributing to tumor angiogenesis and progression. Serum VEGF per platelet count, as an indirect theoretical estimate of VEGF in platelets, may predict the malignant potential of tumors. However, its prognostic significance is still(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)
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)
BACKGROUND The balance in the immune system between immune surveillance against non-self-antigens and tolerance of self-antigens is known to be associated with the prognosis of breast cancer patients. However, immunologic signals in tumor microenvironment according to biological characteristics of cancer cells have not been clearly elucidated. CD4(+) T(More)
Urokinase plasminogen activator receptor (uPAR) plays a major role in cancer invasion and metastasis and uPAR expression is correlated with a poor prognosis in various cancer types. Moreover, the expression of uPAR is increased under hypoxic conditions. Nitric oxide (NO) and its metabolites produced by inducible nitric oxide synthase (iNOS) are important(More)
BACKGROUND Although dietary supplements are commonly taken to prevent chronic disease, the long-term health consequences of many compounds are unknown. METHODS We assessed the use of vitamin and mineral supplements in relation to total mortality in 38,772 older women in the Iowa Women's Health Study; mean age was 61.6 years at baseline in 1986. Supplement(More)
Published studies on the association between the vascular endothelial growth factor (VEGF) gene 936 C/T polymorphism and breast cancer risk are inconclusive, and a meta-analysis is required to verify the association. Nine studies, including a total of 4,973 cases and 5,035 controls, were subjected to meta-analysis. When all eligible subjects were pooled for(More)
BACKGROUND Epidermal growth factor receptor (EGFR) mutations as prognostic or predictive marker in patients with non-small cell lung cancer (NSCLC) have been used widely. However, it may be difficult to get tumor tissue for analyzing the status of EGFR mutation status in large proportion of patients with advanced disease. PATIENTS AND METHODS We obtained(More)
Bone morphogenetic proteins (BMPs) are members of the TGF-β superfamily, and some studies demonstrated that BMPs enhance tumorigenesis and metastasis. The purpose of this study was to identify whether BMP-2 levels are elevated in the serum of non-small-cell lung cancer (NSCLC) patients and are associated with the stage and overall survival. Blood samples(More)
AIMS Cumulative evidence suggests that coffee consumption may have beneficial effects on metabolic diseases; however, few previous studies have considered the types of coffee consumed and the additives used. We investigated the relationship between coffee consumption and metabolic syndrome (MetSyn) and its components. METHODS We analyzed 17,953 Korean(More)
