Aim:
The vascular endothelial growth factor (VEGF) plays a major role in angiogenesis. The association between VEGF 936 C>T (rs3025039) gene polymorphisms and oral cancer (OC) risk is still contentious and ambiguous. To assess the relationship between the VEGF 936 C>T genotype and the risk of developing OC, we performed a meta-analysis to summarize the possible association.
Methodology:
We assessed published studies of the association between 936 C>T polymorphisms and OC risk from four studies with 440 controls and 556 OC cases. We calculated pooled odds ratios (ORs) and 95% confidence interval (CI), considering the frequency of allele, homozygous, heterozygous genotypes and comparison of dominant and recessive genetic models.
Results:
The combined results showed that the T allele was significantly associated with increased OC risk (T vs. C: p=0.001; OR=1.521, 95% CI=1.194-1.938). The heterozygous genotype CT had a 1.5-fold increased risk (CT vs. CC: p=0.002; OR=1.582, 95% CI=1.184-2.114). In addition the dominant genetic model demonstrated a 1.6-fold increased risk of developing OC (TT+CT vs. CC: p=0.001; OR=1.621, 95% CI=1.226-2.143).
Conclusion:
Our results suggest that the VEGF gene polymorphism (936 C>T) contributes increased susceptibility to OC. However, larger studies with a stratified case-control population and biological characterization are needed to validate this finding.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
