Although approximately 25 common genetic susceptibility loci have been identified to be independently associated with breast cancer risk through genome-wide association studies (GWAS), the genetic risk variants reported to date only explain a small fraction of the heritability of breast cancer. Furthermore, GWAS-identified loci were primarily identified in(More)
Ataxia telangiectasia mutated (ATM) cells exist under a constant state of oxidative stress with high levels of reactive oxygen species, which are removed by cellular antioxidant vitamins. We investigated the independent and combined effect of antioxidant vitamins intake and the ATM genotype or diplotype on the breast cancer risk. Analyses included 323 cases(More)
To evaluate the relationship of genetic polymorphism in XRCC3 Thr241Met and the risk of breast cancer, a hospital-based case-control study was conducted in Korea. Histologically confirmed breast cancer cases (n = 574) and controls (n = 502) with no present or previous history of cancer were recruited from several teaching hospitals in Seoul during(More)
BACKGROUND The association of dietary habits and Helicobacter pylori infection with early gastric cancer is still unclear. METHODS A hospital-based case-control study was conducted in Korea. Sixty-nine patients were newly diagnosed as having early gastric cancer at the Division of Gastroenterology, Asan Medical Center, and 199 healthy subjects who visited(More)
The association of animal-origin food consumption and cooking patterns with colorectal cancer (CRC) risk was evaluated in a cohort of 73,224 participants of the Shanghai Women's Health Study. After a mean follow-up time of 7.4 yr, 394 incident cases of CRC (colon = 236; rectal = 158) were diagnosed. Overall, no association was found between the risk of CRC(More)
The prevalence of hypertension has increased over the past decade in many developed and developing countries, including China. This increase may be associated with changes in lifestyle, including dietary patterns. We evaluated the association of dietary patterns with blood pressure (BP) by using data from a large, population-based cohort study of(More)
BACKGROUND Soy food is a rich source of isoflavones--a class of phytoestrogens that has both antiestrogenic and anticarcinogenic properties. OBJECTIVE The objective was to evaluate the association of adolescent and adult soy food intake with breast cancer risk in a cohort of 73,223 Chinese women who participated in the Shanghai Women's Health Study.

BACKGROUND Cruciferous vegetables are the primary source of isothiocyanates and other glucosinolate derivatives that are known to induce phase II detoxifying enzymes, including glutathione S-transferases (GSTs). OBJECTIVE We investigated the independent and combined effects of cruciferous vegetable intake and the GSTP1 Ile(105)Val genetic polymorphism on(More)
To evaluate the relationship of genetic polymorphisms of ERCC2 and ERCC4 genes, both involved in nucleotide excision repair (NER), and the risk of breast cancer, a hospital-based case-control study was conducted in Korea. Histologically confirmed breast cancer cases (n = 574) and controls (n = 502) with no present or previous history of cancer were(More)
OBJECTIVES The aim of this study was to determine whether GSTM1 or GSTT1 might be associated with risk of cervical cancer development in Korean women. The multiplicative interaction of GSTM1 and GSTT1 genotype with p21, p53 polymorphism, and HPV genotype was also investigated. METHODS From 1997 to 1999, uterine cervical carcinoma was diagnosed in 215(More)
