[Relationship between various histological status of margins of LEEP and residual HSIL or worse at hysterectomy following conization].
Objective: To investigate the relationship between various loop electrosurgical excision procedure (LEEP) margin status and residual high grade squamous intraepithelial lesion (HSIL) or worse at hysterectomy following conization. Methods: The relevant clinicopathological data were collected in the Obstetrics and Gynecology Hospital, Fudan University from Jan. 2014 to Dec. 2015, including 947 cases who underwent hysterectomy within 6 months of LEEP. The residual HSIL or worse at hysterectomy were analyzed among the groups. (1) Clear margins, involved margins, and without 1 mm negative margins. (2) Only one positive margin, two positive margins and three positive margins. (3) A positive margin of internal ostium of cervix, of external ostium of cervix and of the basement. ⋯ Conclusions: The risk of residual HSIL or worse is significantly greater with involved margins at hysterectomy following LEEP. Both the positive endocervical and basal margin are excellent predictors of residual diseases, while the without 1 mm negative margin may be not. Clinicians should avoid treating it as positive margin and prevent overtreatment.
