Almost all cases of cervical cancer can be attributed to human papillomavirus (HPV) infection. The loop electrosurgical excision procedure (LEEP) is widely used to treat HPV-mediated disease; thus, cervical cancer is highly preventable. However, LEEP does not necessarily clear HPV rapidly and may affect the accuracy of the results of ThinPrep cytology test (TCT) and cervical biopsy due to the formation of cervical scars.
A 40-year-old woman underwent LEEP for cervical intraepithelial neoplasia grade 1 approximately 10 years ago. Subsequent standard cervical cancer screening suggested persistent HPV-52 infection, but TCT results were negative. Cervical biopsy under colposcopy was performed thrice over a 10-year period, yielding negative pathology results. She developed abnormal vaginal bleeding after sexual activity, persisting for approximately 1 year, and underwent hysteroscopy in our hospital. Histopathologic evaluation confirmed adenocarcinoma in situ of the uterine cervix.
Patients with long-term persistent, high-risk HPV infection and negative pathology results of cervical biopsy after LEEP are at risk of cervical cancer. Hys
Core Tip: The loop electrosurgical excision procedure (LEEP) is widely used to treat human papillomavirus (HPV)-mediated disease; thus, cervical cancer is highly preventable. However, LEEP does not necessarily clear HPV infection rapidly, and patients with persistent HPV infection after LEEP are at risk of cervical cancer. The formation of cervical scars after LEEP may affect the accuracy of ThinPrep cytology test and cervical biopsy results; thus, hysteroscopic resection of cervical canal tissue is recommended as a supplement to cervical biopsy because it helps define the lesion site and may yield a pathologic diagnosis.
