Email: lucia.musacchio@uniroma1.it Abstract Patients with metastatic and recurrent cervical cancer (CC) have a poor prognosis with limited palliative treatment options. Increasing understanding of the cellular aberrations inherent to cancer cells has allowed the development of therapies to target biological pathways, an important step toward the individualization of cancer therapy. The poly (ADPribose) polymerase (PARP) family of enzymes is important in several DNA repair pathways. Drugs that inhibit these PARP enzymes have been investigated in many types of cancer and their application in the treatment of gynecologic malignancies has rapidly evolved. Although the majority of data for PARPi in gynecologic malignancies has been specifically regarding ovarian cancer, their role in the treatment of uterine and CC is currently being investigated. This review will examine PARP inhibitors in CC, summarizes the critical clinical trials of PARP inhibitors that have been completed, provides an overview of the ongoing trials, presents the confirmed conclusions and notes the issues that need to be addressed in future studies.

It is also one of the most common gynecological malignancies diagnosed during pregnancy although, fortunately, it is a rare event (Perrone et al., 2019). The major tumor burden can be observed in less developed regions, representing alone 12% of all female cancers. Human Papillomavirus (HPV) infection is the etiologic factor responsible for the development of almost all CC cases and is also commonly associated with oropharyngeal cancer (Di Domenico et al., 2018). The discrepancy in terms of incidence and mortality of CC between developed and developing countries is probably due to the different diffusion of screening programs consisting of Pap smear, HPV DNA test and Vaccination strategies (Bray et al., 2018; D'Andrilli, Bovicelli, & Giordano, 2010). According to international guidelines, the standard treatment of CC consists of surgery in earlystage tumors, of concomitant chemoradiation or neoadjuvant chemotherapy followed by radical surgery in locally advanced disease and of chemotherapy alone for metastatic or recurrent disease (NCCN guidelines). However, although earlystage and locally advanced disease can be treated with potential curative intent (Pimple, Mishra, & Shastri, 2016),
