Gallbladder cancer (GBC) involves interplay of sex steroids, including estrogen and progesterone. Since CYP17 is a key enzyme involved in estrogen and testosterone hormone biosynthesis as well as in xenobiotic metabolism, it may be a potential candidate gene in the carcinogenesis of the gallbladder.
Polymorphisms in the gene encoding the metabolic enzyme cytochrome P450 1A1 (CYP1A1) might contribute to the variability in individual susceptibility to gallbladder cancer (GBC). This study comprised 142 consecutive cases of proven GBC and 171 healthy participants of similar ethnicity. CYP1A1 6235
BACKGROUND
Lifestyle and dietary habits play an important role in carcinogenesis. Carcinoma of the gallbladder is no different. The present study was carried out to evaluate the roles of lifestyle, menstrual and reproductive factors in gallbladder cancer.
METHODS
A prospective case-control study
OBJECTIVE
To assess the role of nicotine in gallbladder carcinoma and its association with the stage and degree of cancer differentiation.
METHODS
Tissue samples from gallbladder were obtained from 20 patients with gallbladder cancer and 20 age- and gender-matched patients with cholelithiasis who
BACKGROUND
Cyclooxygenase-2 (PTGS2) overexpression has been implicated in various cancers. We aimed to evaluate the role of PTGS2 -1195G>A [reference sequence (rs) 689466], -765G>C (rs20417) and +8473T>C (rs5275) polymorphisms in conferring interindividual susceptibility to gallbladder
CD44 is an important marker for cancer stem cells. Germline variants in CD44 gene have been associated with susceptibility to breast and nasopharyngeal carcinomas but no study in gallbladder cancer (GBC) has been done yet. The present study included 405 GBC patients and 200 healthy controls from
OBJECTIVE
To describe the occurrence of pancreatic, biliary tract, and gallbladder cancers within the Alaska Native (AN) population.
METHODS
Population-based analysis utilizing a tumor registry and comparative population data.
METHODS
Pancreaticobiliary cancers rates for AN people during 1973-2007

Mortality from gallbladder cancer has been traditionally high in Eastern Europe, and lower in northern countries. Trends in 18 European countries, including the European Union (EU) and selected Eastern European countries, have been updated using official death certification data abstracted from the
Together with thyroid cancer, cancer of the gallbladder is the only non-sex hormone-related cancer displaying a female preponderance, with incidence being 3-4 times more common among women. We carried out this study to evaluate the role of menstrual, reproductive and lifestyle factors in gallbladder
OBJECTIVE
Gallbladder carcinoma (GBC) is characterized by a dismal prognosis owing to the paucity of early signs and symptoms. North India reports high incidence of GBC possibly due to environmental, dietary and reproductive factors. Understanding the epidemiology of gallbladder cancer has and will
Liver X receptors (LXRs) α and β are ligand-activated transcription factors belonging to the family of nuclear receptors. LXRs play role in control of lipid homeostasis, glucose metabolism, inflammation, and proliferation. LXRs are expressed in gallbladder cholangiocytes and recent studies have
Inflammation of gallbladder is an established risk factor for gallbladder cancer (GBC) pathogenesis. Chemokine receptors play crucial role in antitumour immunity and are involved in inflammation and pathogenesis of cancers. Present study was aimed to examine the role of CCR5 Delta32 polymorphism in
BACKGROUND
DNA damage by endogenous or exogenous source of reactive oxygen species (ROS) plays an important role in induction and progression of various cancers. Physiologically, gallbladder is likely to be exposed to various ROS which leads to extensive DNA damage. Cells overcome the DNA damage by
OBJECTIVE
GBC is a lethal and multifaceted disease. Deleted in colorectal carcinoma (DCC) is a well known tumor suppressor gene. Recently a small genome-wide association study (GWAS) identified DCC to be significantly associated with gallbladder cancer (GBC) susceptibility in a Japanese population
