Apolipoprotein E epsilon 2 allele and low serum cholesterol as risk factors for gastric cancer in a Chinese Han population.

ABSTRACT: Apolipoprotein E (apoE) mediates lipid metabolism both in peripheral and in the brain. The human APOE gene has three polymorphic alleles that influence the risk for various types of cancer and neurodegenerative diseases. A potential association between APOE allele and the risk for gastric cancer has been implicated, but the specific allele involved and potential associations with the subtype and the grade of cancer malignancy need further clarification. We screened the APOE genotype in 550 gastric cancer patients and 550 non-cancer control individuals and found that the presence of the APOE ?2 and lower serum total cholesterol are associated with an increased risk for gastric cancer (all P???0.0005). Interestingly, APOE ?2 is also correlated with increased risk for both intestinal and diffuse histotypes but not with TN classification or stage in gastric cancer patients, suggesting that APOE polymorphic alleles are associated with the risk of development but unlikely the progression of gastric cancer. Since ?2 carriers have lower levels of serum total cholesterol than non-?2 carriers, our findings suggest that the increased risk for gastric cancer by APOE ?2 allele might be mediated through lowered serum total cholesterol levels.

Project description:Obesity is related to an increased risk of gastric cardia cancer. However, the influences of excess body weight and serum total cholesterol on the risk of gastric high-grade dysplasia have not been fully characterized.A case-control study was conducted to explore the relationships between body mass index (BMI), serum total cholesterol level, and the risk of gastric high-grade dysplasia in Chinese adults. A total of 893 consecutive patients with gastric high-grade dysplasia (537 men and 356 women) and 902 controls (543 men and 359 women) were enrolled from January 2000 to October 2015. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated, and a multivariate analysis was conducted.After adjusting for age, alcohol consumption, smoking status, family history of gastric cancer or esophageal cancer, and serum total cholesterol level, a BMI ranging from 27.5 to 29.9 was significantly related to an increased risk of gastric high-grade dysplasia in both men (adjusted OR?=?1.87, 95% CI?=?1.24-2.81) and women (adjusted OR?=?2.72, 95% CI?=?1.44-5.16). The 2 highest BMI categories (27.5-29.9 and ?30.0) were identified as risk factors for gastric cardia high-grade dysplasia in both men (BMI?=?27.5-29.9: adjusted OR?=?1.78, 95% CI?=?1.02-3.10; BMI ? 30.0: adjusted OR?=?2.54, 95% CI?=?1.27-5.08) and women (BMI?=?27.5-29.9: adjusted OR?=?2.88, 95% CI?=?1.27-6.55; BMI ? 30.0: adjusted OR?=?2.77, 95% CI?=?1.36-5.64), whereas only a BMI ranging from 27.5 to 29.9 was a risk factor for gastric noncardia high-grade dysplasia in both men (adjusted OR?=?1.98, 95% CI?=?1.25-3.14) and women (adjusted OR?=?2.88, 95% CI?=?1.43-5.81). In addition, higher serum total cholesterol was associated with an increased risk of gastric noncardia high-grade dysplasia (adjusted OR?=?1.83, 95% CI?=?1.25-2.69) in women.Increased BMI was associated with an increased risk of gastric high-grade dysplasia in both men and women, and higher serum total cholesterol increased the risk of gastric noncardia high-grade dysplasia in women.
