OBJECTIVE: The aim of our systematic review is the assessment of effects of excisional treatments for the management of cervical intraepithelial neoplasia (CIN) on preterm delivery (PD), lower birth weight (LBW), preterm premature rupture of membrane (PPROM) and obstetrical outcomes.
METHODS: A structured search was carried out in PubMed-Medline, Embase, and Cochrane Controlled Trials Register databases through November 30, 2019. The search included a combination of the following terms:” Loop Electrosurgical Excision Procedure LEEP”,” Large Loop Excision of Transformation Zone LLETZ “,” Cold-Knife Conization CKC”,” Laser Cervical Conization CLC”, “preterm delivery” and “neonatal outcome”.
RESULTS: Thirty-two (32) of 561 publications considered were included: 28 retrospective series, 2 prospective studies and 2 multicenter trials. Globally in several studies there was a significant increase in PD, measured by the relative risk, in the women underwent a surgical procedure for the CIN. In their majority, the studies were retrospective and therefore a high risk of bias.
CONCLUSIONS: This systematic review shows that the surgical treatment of the CIN was associated with an increased risk of PD, LBW and pPROM before 37 pregnancy weeks compared to untreated women, especially in a CKC and LLETZ procedure. Moreover, the increase of the of PD was associated with cone size, cervical length, repeated treatment and a short conization-to-pregnancy interval.
