OBJECTIVES: No consensus exists on the subsequent management strategy of patients who exhibit positive surgical margin (PSM) after re-excision of high-grade cervical intraepithelial neoplasia (CIN). The aim of the study is to examine the predictors related to the persistence of high-grade CIN lesions after re-excision, where PSM was left behind. MATERIAL AND METHODS: The present retrospective study included patients with PSM who underwent repeated conization due to residual high-grade CIN lesions between January 2005 and December 2019. The SPSS software v20.0 was used for data interpretation and statistical analysis. P values less than 0.05 were accepted as statistically significant. RESULTS: Repeat conization was performed in 91 patients, 43 (47.3%) presented with PSM with high-grade CIN, 6 (6.5%) presented with micro-invasive carcinoma, and 42 (46.2%) presented with clear surgical margin or CIN 1 at the surgical margin. At the time of conization, patients who presented with lesions > 5 mm in repeat cone specimens, exhibited a significantly higher rate of residual disease (p < 0.001). Besides, the involvement of the endocervical margin with high-grade CIN was the predictor of residual disease in repeat cone specimens (p = 0.006). CONCLUSIONS: In the cone specimen, the presence of lesion size greater than 5 mm and involvement of the endocervical margin were the predictors of high-grade residual disease after re-excision. Whether it is the first or second procedure, great care must be given to excise the lesion entirely at the time of the conization, preferably in one piece.
