Safety of LEEP in Treating CIN 2-3 During Pregnancy

Cervical intraepithelial neoplasia (CIN) 2-3, a premalignant lesion usually treated by Loop Electrosurgical Excision Procedure (LEEP) in nonpregnant women, is addressed differently in pregnant women. Data from 2006 to 2023 on 178 pregnant women with CIN 2-3 were provided by the Israeli Society of Colposcopy. Sixty-seven underwent LEEP within 15 weeks of gestation with only minor complications. Of the 57 continuing pregnancies, 53 (93%) delivered at term, 2 (3.5%) at 34-37 weeks, and 2 (3.5%) experienced missed abortions. One hundred eleven women were followed through pregnancy without LEEP. Of that group, 5 women were lost to follow-up. From 173 women on whom the authors have follow-up data, 9 (5.2%) were finally diagnosed with cervical cancer, 132 women (76.3%) remained CIN 2-3, and 32 women (18.5%) were CIN 1 or normal. Loop Electrosurgical Excision Procedure (LEEP) performed within the first 15 weeks of pregnancy in 67 women was safe. In 5.2% of pregnant women with CIN 2-3, the final diagnosis was invasive cancer.
