Human papilloma virus infection and cervical cytomorphological changing among intrauterine contraception users.

OBJECTIVE

The increased use of the intrauterine contraception (IUC) in female population and its probable relationship with cervical squamous intraepithelial lesions and cervical cancer make necessary clarify the possible interaction between the device and the pre-neoplastic lesions.

PATIENTS AND

METHODS

Seven hundred and eighty-nine patients users of IUC and 1491 patients ever users of IUC were followed every 6 months for 3 years. Each clinical control included Papanicolau test, colposcopy, HPV-DNA test and HPV-mRNA test. Also, in patients IUC users we analyzed the type of device, years of use and average age.

RESULTS

Cytological sampling, histological examination, HPV-DNA test and HPV-mRNA test showed that there are not significantly differences between patients with or without IUC.

CONCLUSIONS

None difference arose regarding persistence and progression between patients IUC users and IUC no users, for this reason, intrauterine contraception does not seem to be a co-causal factor in the possible development of cervical cancer.
