Recurrent Rates with Cervical Intraepithelial Neoplasia having a Negative Surgical Margin after the Loop Electrosurgical Excision Procedure in Thailand |

| Abstract: | LEEP conization has become the treatment of choice in patients presenting with high grade intraepitheliallesions (HSILs) especially in cases with negative surgical margins. However, surveillance after such treatmentis necessary due to the potential for recurrence. To evaluate the recurrent rate in patients with negative surgicalmargins after HSIL treatment with LEEP, the medical records of such patients treated between January 2000and June 2007 were reviewed. All of them subsequently underwent Pap smears every 4-6 months to detect therecurrence of cervical intraepithelial neoplasia. There were 272 patients in the study period. Of these, 9 (3.3%)developed abnormal Pap smears with a median follow up of 12 months. The abnormal smears featured: atypicalsquamous cells of undetermined significance in 5 cases; atypical squamous cells where high grade squamouscell intraepithelial lesion cannot be excluded in 2 cases; and low grade squamous intraepithelial lesions in the 2remaining cases. Further investigation with colposcopic directed biopsies were conducted in all who exhibitedan abnormal Pap smear and only 3 of them (1.1%) showed cervical dysplasia at biopsy. In conclusion, thepatients with HSIL who were treated with LEEP and have negative surgical margins have a very low recurrencerate. |
