Abstract (EN): Invasive squamous cell carcinomas of the cervix arise from earlier, reversible precursor lesions called low- and high-grade squamous intraepithelial lesions ( LSIL and HSIL, respectively). The aim of our study was to analyse the influence of the CCR2-64I polymorphism in the development of SIL due to its preponderant role in the cervical carcinogenesis and in the progression of these lesions to invasive cervical carcinoma. We conducted a case-control study, analyzing 565 Caucasian women from the north of Portugal. The CCR2-64I polymorphism was analysed through polymerase chain reaction followed by restriction fragment length polymorphism. The frequency of GG, GA and AA genotypes was 76.5, 23.5 and 0.0% respectively, in HSIL patients, and 87.8, 11.1 and 1.1% respectively, in the control group. The G allele frequency was 88.2% in the HSIL group and 93.4% in the control group. Regarding the A allele frequency, it was 11.8% in the HSIL group and 6.6% in the control group. Overall, the frequency of A carrier genotypes was higher in HSIL patients than in the control group ( p = 0.013; OR = 2.21; 95% CI: 1.17 4.15), suggesting that CCR2-64I polymorphism might contribute to the establishment of HSIL, through the disruption of the naturally fragile immune response directed towards human papillomavirus infection.
