We evaluated the association between dietary patterns and breast cancer risk according to menopausal and hormone receptor status among Korean women. In a study with 357 cases and 357 age-matched controls, dietary patterns (vegetable-seafood and meat-starch) were derived via principle component analysis based on 39 food groups from a food frequency questionnaire. The relation between dietary patterns and breast cancer risk was assessed by using multivariate logistic regression. The vegetable-seafood pattern was inversely associated with breast cancer risk [odds ratio (OR) and 95% confidence interval (CI) for high vs. low intake = 0.14 (0.08-0.25); P for trend < 0.001]. No association between the meat-starch pattern and breast cancer risk was found. The association between dietary patterns and breast cancer risk was not modified by menopausal and combined hormone receptor status. These findings indicate that a diet rich in vegetables and seafood is associated with a decreased breast cancer risk in Korean women.
[Show abstract][Hide abstract] ABSTRACT: Because diet is closely related to cancer incidence and mortality, recent studies in cancer epidemiology have focused on dietary factors. The results of studies on nutritional cancer epidemiology in Korea are discussed in this research paper. Most studies have used a case-control design focused on breast or gastric cancer patients. Antioxidants were associated with a reduced risk of gastric cancer in most studies, but this association was not observed for breast cancer. Most diets consumed by Koreans that included fruits and vegetables were associated with reduced cancer risk, but high concentrations of salt in food were positively associated with gastric cancer risk. Genetic susceptibility was considered in several studies, and food contaminants were assessed to estimate life-time cancer risk. Recent studies have made advances in understanding the relationship between diet and cancer among Korean populations. However, because the history of nutritional cancer epidemiology in Korea is relatively short, the subjects covered and methodology of the research have been limited. A cohort design with a large sample size and appropriate methods to assess subjects' usual intake may be needed to determine the true association between diet and cancer in the future.

[Show abstract][Hide abstract] ABSTRACT: This systematic review collates research on the topic of dietary patterns and breast cancer risks. The literature search targeted epidemiological studies published up to December 2012 and was conducted using the Medline (U.S. National Library of Medicine, Bethesda MD, USA) and Lilacs (Latin American and Caribbean Health Sciences, São Paulo, Brazil) databases. The following search terms were used: breast cancer, breast neoplasm, breast carcinoma, diet, food, eating habits, dietary patterns, factor analysis, and principal component analysis. Only studies that used factor analysis techniques and/or principal component analysis were eligible, and a total of 26 studies were included. The findings of these studies suggest the Mediterranean dietary pattern and diets composed largely of vegetables, fruit, fish, and soy are associated with a decreased risk of breast cancer. There was no evidence of an association between traditional dietary patterns and risk of breast cancer, and only one study showed a significant increase in risk associated with the Western dietary pattern. Diets that include alcoholic beverages may be associated with increased risk.
[Show abstract][Hide abstract] ABSTRACT: Cancer screenee cohort study at National Cancer Center (NCC) was first established in 2002 for the foundation of research studies to investigate all possible risk factors related to cancers and to expand biological specimen banking to determine the effective methodology for cancer detection, diagnosis, and prevention. As of May 23rd in 2014, total 40,709 participants are enrolled in this cohort study. The information on participants' health included questionnaire, clinical result, physical examination, cancer screening, and biological specimen test including blood, urine, and exfoliated cervical cells. Thyroid cancer has been the top occurring cancer type in a nested case-control study design when linked to national cancer registry information as of December 31st, 2011. The studies related with chronic diseases including cancer were published in scientific journals; case-controls, cross-sectional, and cohort since 2009. Categorized by research topic, the studies related with diet and nutrition were published the most, followed by gene, HBV and liver cancer screening, methodology, physical activity, obesity, metabolic syndrome, smoking and alcohol consumption, and blood type. The achievement of scientific evidence-based screenee cohort study at NCC is highly anticipated to reduce the burden of cancer in Korean population for cancer detection, diagnosis, and prevention for the next decades.
