Inflammatory gene variants and the risk of biliary tract cancers and stones: a population-based study in China
Menée en Chine (1 438 cas et 860 témoins), cette étude en population évalue la relation entre 35 polymorphismes à simple nucléotide de 5 gènes associés au processus inflammatoire et le risque de cancer des voies biliaires ou de calculs biliaires
BACKGROUND:Genetic variants in inflammation-related genes have been associated with biliary stones and biliary tract cancers in previous studies.METHODS:To follow-up on these findings, we examined 35 single nucleotide polymorphism (SNPs) in 5 genes related to inflammation (IL8, NFKBIL, RNASEL, TNF, and VEGFA) in 456 participants with incident biliary tract cancer cases (262 gallbladder, 141 extrahepatic bile duct, 53 ampulla of Vater), 982 participants with biliary stones, and 860 healthy controls in a population--based case--control study in Shanghai, China.RESULTS:Suggestive associations were observed for SNPs in VEGFA with biliary stones, IL8 with gallbladder and ampulla of Vater cancers, and RNASEL with ampulla of Vater cancer (false discovery rate<=0.2).CONCLUSION:These findings provide additional support for the role of inflammation in biliary stones and biliary tract cancer risk and need further validation.
