OBJECTIVE: To assess the safety of conservative management of cervical intraepithelial neoplasia grade 2 (CIN2) in women aged under 30 years. STUDY DESIGN: A retrospective cohort study at Queen's Hospital, London, UK. We reviewed patient records and 'Open Exeter' cytology results of 178 women aged less than 30 years with histologically proven CIN2 between 1st April 2014 and 31st March 2016. Analysis included rates of spontaneous regression of CIN2, the persistence of abnormality, the progression to CIN3 and cancer, duration of conservative management, and the number of patients that defaulted follow-up. RESULTS: Of 178 women, 69 women underwent primary treatment of CIN2 with large loop excision of the transformation zone (LLETZ). Nine women defaulted follow-up after their first appointment. One hundred women were managed conservatively with colposcopy, cytology and cervical biopsy. Overall 57% had successful conservative management with regression of high-grade lesion on colposcopy and negative cytology; 32% had failed conservative management and LLETZ, and 11% of women defaulted follow-up with abnormal cytology. Only 13% of women managed conservatively progressed to CIN3, with no woman developing cancer at a median follow-up of 22 months. In women with successful conservative management features of high-grade dysplasia on colposcopy resolved in a significantly shorter time-period compared to normalisation of their cytology (p = 0.021). CONCLUSION: Conservative management of CIN2 appears reasonable and safe in women under the age of 30 years, with 57% showing regression to negative cytology. There is a significant time lag before cytology becomes negative, so early recourse to treatment based on cytology alone is not advised where colposcopy is satisfactory and reassuring. Crown
