Follow-up After Loop Electrosurgical Excision of Cervical Intraepithelial Neoplasia: The Use of Combined Cytology and Human Papillomavirus Testing.

Abstract

The aims of the study were to investigate how many women after 1 or 2 follow-up examinations, based on combined cervical cytology and human papillomavirus (HPV) testing, could finish posttreatment follow-up and continue with the general screening program and to determine the 5-year risk of recurrence in this group. This is a prospective observational study that includes women, who underwent loop electrosurgical excision procedure (LEEP) in the North Denmark Region, from January 1, 2012, to May 31, 2014. All included women had histologically verified diagnosis of high-grade cervical intraepithelial neoplasia (CIN 2+) or adenocarcinoma in situ (AIS) before LEEP and posttreatment follow-up with cervical cytology and HPV combination testing. Study period was until October 2019. Totally, 563 women were included in the study. After finishing the posttreatment follow-up, 439 (78%) could continue to the general screening program and 362 of them had a screening during the study period. Six women (1.7%) had either cervical dysplasia and/or HPV infection in the cervical screening, and of these, 3 (0.8%) had high-grade dysplasia corresponding to CIN 2. None was diagnosed with CIN 3, AIS, or invasive carcinoma. One hundred twenty-one women (36%) chose to be screened sooner than recommended in the national guidelines. Human papillomavirus and cytology combination test after LEEP allows women, irrespective of margin status, safely to continue with the general screening program after a short posttreatment follow-up period. Improved information is mandatory to reduce "opportunistic" screening after finishing posttreatment follow-up.
