Objective: Human papillomavirus (HPV) is the most important pathogenetic factor of intraepithelial neoplasias of the lower genital tract. HPV-DNA and mRNA tests are applied for the management of epithelial dysplasias. The aims of this multicentric retrospective study were to compare the 2 molecular tests before the onset of metachronous intraepithelial lesions and to analyze the different characteristics between synchronous and metachronous lesions and their relationship to the pathologic mechanisms.

Materials and Methods: The study concerns 55 cases of multiple intraepithelial neoplasias of the lower genital tract. Clinical features of patients with synchronous and metachronous lesions were analyzed. During a 3-year follow-up, HPV-DNA and mRNA tests were performed every 6 months after treatment of the initial lesion. HPV-DNA and mRNA results were analyzed 12 and 6 months before, at time of the onset of the metachronous lesion, and 6 months after its treatment.

Results: We observed 31 synchronous lesions and 24 metachronous lesions. Immunodeficiency and multiple genotypes were associated with the synchronous lesions (p = .04 and p = .02, respectively). During the follow-up, positive DNA and mRNA tests increased before the appearance of the metachronous lesion and decreased 6 months after; mRNA test was significantly better than the DNA test 6 months before the appearance of the lesion (p = .04) and at the time of its appearance (p = .02).

Conclusions: Our results support the hypothesis that a positive HPV-mRNA test could be a marker of persistent infection and a risk factor for the onset of metachronous lesions.
