The investigators hypothesis is HPV integration could result in expression of oncogene transcripts, and not only constitutive expression but also the level of expression will be decisive for transformation and the maintenance of the malignant phenotype. Moreover, the expression and level of HPV viral transcripts not HPV DNA viral loads is correlated to the severity in cervical intraepithelial neoplasia (CIN) and cervical carcinomas (CxCa).
