| Abstract: | P53 codon 72 polymorphisms have been reported to be associated with cancers of the lung, esophagus and cervix. However, there have been no reports on the interaction of select risk factors and p53 codon 72 polymorphisms in gastric cancer susceptibility. 155 gastric cancer cases and 134 cancer-free controls were enrolled at the Memorial Sloan Kettering Cancer Center (MSKCC) from November 1992 to November 1994. The crude odds ratio (OR1) associated with the (Pro/Pro) polymorphism and the risk of gastric cancer was 1.27 (0.70-2.33). Adjusting for age, sex, race and education (OR2) and further adjusting for BMI, calories, sodium, smoking, vitamin C, fiber, alcohol, fat, and H. pylori status (OR3) did not yield significant results. Significant joint effects were associated with high fat consumption (OR1=2.61 (95% CI:1.13-6.06); OR2=2.85 (95% CI:1.14-7.15) for total cancers and for proximal tumors (OR1=2.56 (95%CI:1.00-6.54)). The low vitamin C intake/high-risk polymorphism group (Pro/Pro) had an OR1 of 4.82 (95% CI: 1.72-13.45) and the OR2 was 6.19 (95% CI: 2.08-18.40) for distal tumors. The point estimates were increased for interaction odds ratios but not statistically significant (OR1=4.25 (95% CI: 0.66-27.50); OR2=4.73 (95% CI: 0.67-33.43); OR3=5.55 (95% CI: 0.66-46.47)). Further studies specifically looking at proximal and distal tumors are required to confirm any potential interaction between the p53 codon 72 polymorphisms and environmental risk, in particular low dietary vitamin C and high fat consumption. © 2005. |
