Objective Conservative management of cervical intraepithelial neoplasia (CIN) grade 2 in women younger than 25 years may reduce overtreatment. However, long-term efficacy remains uncertain. This retrospective cohort study aimed to determine the rate of recurrence of high-grade abnormalities among young women with a history of CIN 2 that spontaneously regressed within 2 years and compare this with the rate of high-grade abnormality in similar women with an initial diagnosis of CIN 1. Study Design We identified all women aged younger than 25 years who were diagnosed with CIN 1 or CIN 2 between January 2005 and August 2009 within 2 colposcopy units. Follow-up data from the National Cervical Screening Programme were obtained to identify those women who developed recurrent high-grade lesions before October 2012. Comparisons were made using Cox proportional hazards regression. Results A total of 683 women were included: 106 with CIN 2 that spontaneously regressed, 299 with treated CIN 2, and 278 with conservatively managed CIN 1. Median follow-up was 4 years. There was no significant difference in the risk of development of high-grade abnormalities after 2 years between the spontaneously regressing CIN 2 and CIN 1 groups ( P = .83). Women with treated CIN 2 had a significantly lower risk of recurrence than women with untreated CIN 2 ( P = .01). Conclusion CIN 2 that has spontaneously regressed appears to behave as a low-grade lesion. This study contributes to the growing body of evidence that careful observation of CIN 2 is an efficacious and appropriate initial management option for women aged younger than 25 years at diagnosis.
