Dietary folate as well as polymorphic variants in one-carbon metabolism genes may modulate risk of breast cancer through aberrant DNA methylation and altered nucleotide synthesis and repair. Alcohol is well recognized as a risk factor for breast cancer, and interactions with one-carbon metabolism has also been suggested. The purpose of this study is to test(More)
Cancers of the colon and rectum are rare in developing countries, in contrast to the high incidence rates in countries of Europe, North America, Australia and Japan. Significant differences also exist within continents. Colorectal cancer mortality and incidence rates have decreased in the USA. However, the incidence in Japan and Thailand is rising, probably(More)
Chronic inflammatory processes induce oxidative and nitrative stress that trigger lipid peroxidation (LPO), whereby DNA-reactive aldehydes such as trans-4-hydroxy-2-nonenal (HNE) are generated. Miscoding etheno-modified DNA adducts including 1,N(6)-etheno-2'-deoxyadenosine (epsilondA) are formed by reaction of HNE with DNA-bases which are excreted in urine,(More)
PURPOSE To detect and characterize amplified DNA sequences in cholangiocarcinoma (CCA). PATIENTS AND METHODS We extracted DNA from tumor and corresponding normal tissues of 30 patients with CCA and amplified with 30 random ten-mer arbitrary primers by the arbitrarily primed polymerase chain reaction (AP-PCR) technique. RESULTS Our results showed gains(More)
Most patients with liver cancer are diagnosed when they are not suitable for resection. Although some palliative approaches can be applied to these patients, the overall survival rate remains unsatisfactory. Active hexose correlated compound (AHCC), a newly developed functional food, has been shown to act as a potent biological response modifier in in vitro(More)
Estrogen and its metabolites are believed to play important roles in breast cancer, and its determinants include both genetic and lifestyle factors. The objective of the study is to investigate the association of breast cancer risk in Thailand with genetic polymorphisms in several genes involved in estrogen synthesis and metabolism. Five hundred and seventy(More)
The countries of mainland South-East Asia, Myanmar, Thailand, Laos, Cambodia and Viet Nam, share a long history of interactions and many cultural similarities, as well as geographical contiguity. They therefore can be usefully examined as a group when considering measures for control of cancer and other non-communicable diseases. Liver cancer is(More)
OBJECTIVE Colorectal cancer (CRC) is the third-most and fifth-most common cancer in men and women, in Thailand. The increasing CRC incidence and mortality can be reduced by screening and treating adenomas and early cancers. A pilot CRC screening programme using immunochemical faecal occult blood testing (iFOBT) and colonoscopy for test-positives were(More)
Breast cancer is common malignancy in Thai female. Although there are well established risk factors, many environmental agents with an impact are still unknown especially with reference to occupation. The objective of this study was to investigate the risk of female breast cancer among different occupational categories in Thailand. A frequency-matched(More)
