The Role of Medical Therapies in the Management of Cervical Intraepithelial Neoplasia: A Narrative Review
Cervical cancer and its precursors (cervical intraepithelial neoplasia (CIN)) represent a current major public health concern. Currently, the treatment of choice for patients with HSILs (high-grade intraepithelial lesions) is surgical treatment—LEEP or cold-knife conization—except for in pregnant women, where it may have significant future consequences. In this paper, we aim to review the current evidence regarding the efficacy of non-surgical approaches for CINs. Therefore, we searched Google Scholar and PubMed for papers on CIN treatments; 91 studies published in English were included in the analysis. The results of the reviewed studies were variable depending on the agent and methodology used. Overall, the remission rates of CIN II ranged from 43 to 93%. However, for some agents, the results were contradictory. Once topical agents have been proven to be effective, they could be used as an alternative to surgical methods in treating HPV-associated CIN, with fewer adverse effects. The use of local agents could allow for more personalized treatments for patients with CINs. Future directions were also sought.
