Summary: The molecular epidemiologic data showed in an unequivocal manner that the human papillomaviruses (HPVs) are the etiologic agent of this disease. There is not a consensus regarding the inclusion of some genotypes with low prevalence in a special risk group. The genital infection with HPV must be managed as a higher risk (Hr) factor which predispose to the cervical cancer development. In this infection, the certainly diagnosis is done by PCR, so, it is not surprisingly that at the international, but also the national level, there are numerous studies focused on the value of the high specificity grade enabled by these assays, in order to eliminate cyto/colposcopic discordances. It is generally admitted that the HrHPV infection is not sufficient for the cervical cancer pathogenesis, other complementary conditions being involved The reason that certain infections are persistent may depend on: the inter-individual variations in the capacity to elicit an adequate immune response; the persistence and the clonal viral heterogeneity; – the viral oncogenes interference with the tumour suppressor proteins; the epigenetic events.
In this context we intend to verify the accuracy of the cytologic diagnosis on thin layer preparations ( Thin Prep), as compared with classical techniques; to evaluate the consistency relation between the immunocytochemical determination of the Hr HPV L1 proteins and the PCR detection of the corresponding viral genome, in order to monitories the evolution; to quantify the expression of some cell and viral genes involved into the inter-individual variations of the immune response, in the viral persistence and in the progression of the genital lesions;
