Aim: To inquire into whether there is any relationship between MMP-2 rs2285053 and MMP-9 rs3918242 polymorphisms and the onset risk of cervical cancer (CC) and invasion and metastasis.
Methods: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was utilized to examine the frequency and distribution of MMP-2 rs2285053 and MMP-9 rs3918242 polymorphisms in 150 CC patients and 120 healthy individuals who were matched therewith in age and gender, and the CC risk and invasion and metastasis condition of individuals carrying different genotypes of the two single nucleotide polymorphisms (SNPs) were compared. The data were processed by SPSS 18.0 software.
Results: The differences of genotype distribution frequencies of the two SNPs between the two groups were not apparent (P > 0.05), and no significant relevance was found between the two SNPs and the lymphatic metastasis of CC. The CC risk for those carrying CC/TT (rs2285053) and CT/TT (rs3918242), CC (rs2285053) and CC (rs3918242), and CC (rs2285053) and CT/TT (rs3918242) respectively was 0.135, 1.138, and 1.182 times as much as that for those carrying CT/TT (rs2285053) and CC (rs3918242) (95% CI=0.028-0.660; 95% CI=0.615-2.103; 95% CI=0.558-2.502), reflecting that the two SNPs had interactions there between.
Conclusions: MMP-2 rs2285053 and MMP-9 rs3918242 polymorphisms may have correlations with CC susceptibility.
