Abstract
PURPOSE OF INVESTIGATION: The absence of cervical intraepithelial neoplasia (CIN) in a loop electrosurgical excision procedure (LEEP), cold-knife conization and hysterectomy for treatment of CIN is an occasional finding of uncertain clinical significance. The aim of this study was to estimate the frequency of a negative procedure and its relationship to disease recurrence. METHODS: A retrospective study was conducted on 263 specimens from women submitted to the LEEP (n = 142), conization (n = 101) or hysterectomy (n = 20) due to CIN. RESULTS: The frequency of negative conization, LEEP and hysterectomy were, respectively, 15.5%, 19.8% and 25%. Recurrence occurred from 16 to 44 (median = 42) months in women with negative surgical specimens (LEEP or cold knife conization), and after five to 31 (median = 20) months after histological findings of CIN in surgical specimens, respectively, 7.1% and 11.2%. CONCLUSION: The absence of CIN in those procedures of biopsy-confirmed CIN is a not an uncommon finding. Patients with positive or negative specimens should be carefully followed.
