The loop electrosurgical excision procedure (LEEP) is widelyused to treat HPV-mediated disease;thus, cervical cancer is highly preventable.However, LEEP does not necessarily clear HPV rapidly and may affect theaccuracy of the results of ThinPrep cytology test (TCT) and cervical biopsy due tothe formation of cervical scars.CASE SUMMARYA 40-year-old woman underwent LEEP for cervical intraepithelial neoplasia grade1 approximately 10 years ago. Subsequent standard cervical cancer screeningsuggested persistent HPV-52 infection, but TCT results were negative. Cervicalbiopsy under colposcopy was performed thrice over a 10-year period, yieldingnegative pathology results. She developed abnormal vaginal bleeding after sexualactivity, persisting for approximately 1 year, and underwent hysteroscopy in ourhospital. Histopathologic evaluation confirmed adenocarcinoma in situ of theuterine cervix.CONCLUSIONPatients with long-term persistent, high-risk HPV infection and negative pathologyresults of cervical biopsy after LEEP are at risk of cervical cancer. Hysteroscopicresection of cervical canal tissue is recommended as a supplement tocervical biopsy because it helps define the lesion site and may yield a pathologicdiagnosis.展开更多
