Conservative management of biopsy confirmed high-grade squamous intraepithelial lesions

Abstract

OBJECTIVES: Follow-up of women with biopsy-confirmed CIN2+ who were either treated immediately with LLETZ or managed conservatively to determine the rates of patients back on routine screening programme after a median of three years in two groups. METHODS: In this retrospective study, 310 patients were involved who had undergone biopsy with result of CIN2+ between January 2011 and December 2014. Depending on the management, i.e. based on whether cytology and colposcopy follow-up or immediate treatment were performed, they were divided in two groups. Then the number of patients back on routine screening up to 15/2/2016 as well as the results of last cytology were compared within both groups. RESULTS: A total of 310 women at average age of 30 years met the inclusion criteria. Of them, 230 (74 %) had immediate treatment whereas 80 (26 %) were managed conservatively. There were no statistically significant demographic differences between the two groups. The mean time of follow up was 1.091 days (2.98 years). The patients managed conservatively required more follow-up visits at colposcopy clinic (p < 0.001). The last documented cytology in the immediate treatment group was negative in 93 % and low-grade/borderline in 7 % of patients, while in the conservative management group, it was negative in 84 %, low-grade/borderline in 15 % and high-grade in 1 % of patients (p = 0.015). Overall, the proportions of patients who are back on routine screening recall are 96 % and 87.5 % for the immediate treatment and conservatively managed groups, respectively (p=0.022). CONCLUSION: The conservative management of high-grade CIN with cytology and colposcopic follow up is an OPTION in selected group of patients, but it cannot be routinely recommended (Tab. 2, Ref. 20).
