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)
Cholangiocarcinoma is relatively rare, but high incidence rates have been reported in Eastern Asia, especially in Thailand. The etiology of this cancer of the bile ducts appears to be mostly due to specific infectious agents. In 2009, infections with the liver flukes, Clonorchis sinensis or Opistorchis viverrini, were both classified as carcinogenic to(More)
There are five population-based cancer registries in Thailand in different regions of the country. Four of them (Chiang Mai, Khon Kaen, Bangkok, and Songkhla) have been operating since 1988 and the other (Lampang) since the early 1990s. These registries have published regular 3-year cancer incidence reports since the first in 1993 for the period 1989-1991.(More)
DNA repair plays an important role in tumor development. The base excision repair (BER) pathway mainly removes DNA damage caused by ionizing radiation and reactive oxidative species. Here, we examined possible associations between polymorphisms in three important BER genes (OGG1 Ser326Cys, APEX1 Asp148Glu, XRCC1 Arg194Trp, XRCC1 Arg280His, XRCC1 Arg399Gln)(More)
BACKGROUND Liver cancer is the most frequent cancer among Thais especially people in northeastern Thailand, but there has as yet been no assessment of trend. The data of all cancers in Khon Kaen can be retrieved from data base of the Khon Kaen Cancer Registry (KKCR) which was established in 1984. OBJECTIVE To assess the incidence trend of hepatocellular(More)
BACKGROUND Previous population-based incidences of childhood cancer in Thailand were achieved by extrapolating from data limited to a small number of cancer registries, not from the whole country. In addition, survival of childhood cancer patients is often described in specialized hospitals and/or institutions, but not in the general population. METHODS(More)
The 19p13.1 breast cancer susceptibility locus is a modifier of breast cancer risk in BRCA1 mutation carriers and is also associated with the risk of ovarian cancer. Here, we investigated 19p13.1 variation and risk of breast cancer subtypes, defined by estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2)(More)
BACKGROUND The term "cholangiocarcinoma" was originally used only for intrahepatic bile duct (adeno)carcinomas, but is now regarded as inclusive of intrahepatic, perihilar, and distal extrahepatic tumors of the bile ducts. A rise in incidence of intrahepatic cholangiocarcinoma has been recently reported in Western countries but comparatively little is known(More)
Intestinal parasitic infections (IPIs) are still important to the health of Thai rural residents. IPIs are the cause of many chronic diseases with, for example, opisthorchiasis resulting in progression to cholangiocarcinoma (CCA). This cross-sectional study in a prospective cohort study aimed to examine the prevalence and co- infection of intestinal(More)
BACKGROUND The incidence of colorectal cancer is variable around the world. Hiroshima, Japan had the highest incidence in men in 1997 with an age-standardized rate of 86.7 per 100,000 and New Zealand had the highest, at 40.6 per 100,000, in women. The incidence of colorectal cancer in Thailand is rather low and the latest figures for Northeast of Thailand(More)
