摘要:: The association between polymorphisms in vascular endothelial growth factor (VEGF) +936C>T and cyclin D1 (CCND1) +870A>G genes, oral cancer risk, and disease-free survival remains controversial. We found no association between polymorphisms in the CCND1 and VEGF genes and oral cancer development using multivariate logistic regression analysis. Clinical data indicated that the VEGF +936C>T polymorphisms were associated with larger tumor size and advanced cancer stage, but the χ(2) test did not show that CCND1 polymorphisms were associated with larger tumor size and advanced cancer stage. However, Cox proportional hazards model analysis showed no correlation between the VEGF +936C>T polymorphisms and poor disease-free survival. The CCND1 +870A>G polymorphisms (hazard ratio (HR)=1.62, 95% CI=1.10-2.46; adjusted HR=1.63, 95% CI=1.08-2.54) and larger tumor size were associated with poor 5-year disease-free survival by the log rank test and multivariate Cox proportional hazards model analysis. We hypothesized that polymorphisms in CCND1 +870A>G and VEGF +936C>T genes are not correlated with the development of oral cancer. We found the CCND1 +870G allele to be an independent risk factor for poor 5-year disease-free survival in oral cancer patients. VEGF +936C>T polymorphisms were not directly correlated with poor survival, but they might be associated with increased tumor size, which affected our disease-free survival results.
