PURPOSE: E-cadherin is a transmembrane glycoprotein with important roles in the maintenance of cervical squamous epithelium integrity. The purpose of this study was to investigate the relationship between E-cadherin-160 C/A polymorphism and cervical intraepithelial neoplasia (CIN). METHODS: A case-control study was performed enrolling 70 CIN cases and 107 age-matched healthy controls. Each patient was examined colposcopically, having a cervical specimen. All patients and controls have been genotyped for E-cadherin-160. Data were analysed using odds ratios (OR) and chi-square test at a significance level of p<0.005. RESULTS: The presence of E-cadherin-160 C/A was significantly associated with high-grade squamous intraepithelial lesion (HSIL) (OR=2.7916, 95% CI 1.1495,6.9345, x2=6.33, p=0.0118) and carcinoma in situ (CIS) (OR=2.5617, 95% CI 1.1676,5.6705, x2=6.63, p=0.0100). The detection of either CA or AA genotype was also significantly associated with HSIL and CIS. CONCLUSION: E-cadherin-160 genotype represents a valid risk factor for HSIL and CIS.
