Introduction. Association studies have shown that gene polymorphisms in
various classes of genes can modulate cancer risk. The -31G/C polymorphism in
the promoter of survivin gene, affects the expression of the anti-apoptotic
protein survivin which in turn may predispose an individual to some types of
cancer. Objective. The aim of the study was to determine whether the survivin
promoter -31G/C polymorphism could be a susceptibility factor for squamous
cell carcinoma (SCC) of the oral cavity and basal cell carcinoma (BCC) of the
skin. Methods. The DNA obtained from 88 patients with SCC, 60 patients with
BCC and 111 healthy individuals was subjected to polymerase chain
reaction-restriction fragment length polymorphism analysis (PCR- RFLP) in
order to determine genotype and allele frequencies in patients and control
groups. Logistic regression was used for cancer risk assessment. Results. The
following distribution of genotypes was obtained: CC genotype 15% in the SCC
group, 13% in the BCC group and 12% in controls; CG genotype 41% in SCCs, 35%
in BCCs, 48% in controls; GG genotype 44% in SCCs, 52% in BCCs and 40% in
controls. Allelic frequencies were as follows: G allele 0.65 in SCCs, 0.69 in
BCCs and 0.64 in the control group; C allele 0.35 in SCCs, 0.31 in BCCs and
0.36 in the control group. There was no statistically significant difference
in allele or genotype frequencies between the patients and controls (p>0.05).
Conclusion. In Serbian population, -31G/C polymorphism in the promoter of the
survivin gene cannot be considered as a risk factor for oral squamous cell
carcinoma and skin basal cell carcinoma.
