Abstract

Introduction: Human papillomavirus (HPV) infection is an objective marker with a high sensitivity for finding cervical dysplasia. The objective of the current study is to investigate whether HPV testing, combined with liquid-based cytology, is reliable as a test of cure after the loop electrical excision procedure (LEEP). Material and methods: The LEEP was performed in 330 women for excision of cervical dysplasia. Follow up consisted of HPV testing and liquid-based cytology at six, 12, and 36 months after treatment. Patients with negative co-testing after 6 months were re-examined after 3 years. Patients who tested positive for high-risk HPV and/or dysplasia were followed up 12 months postoperatively. Results: At 6 months, the co-testing was double negative in 169 of 260 tested cases (65%). A positive high-risk HPV test (n = 40) was associated with cytological abnormalities (p < 0.001). After 3 years, 227 of 275 examined cases (83%) co-tested negative, including 154 patients who had already tested negative at 6 months and 37 cases with viral clearance at 12 months. Of 26 patients with high-risk HPV at the 3-year follow up, six had LSIL findings on liquid-based cytology, but neither HSIL lesions nor glandular atypia or cervical cancer was found. A negative high-risk HPV test showed a negative predictive value for HSIL of 100% (95% CI 99.8–100%). Conclusions: Negative co-testing 6 months after LEEP can be considered a reliable test of cure as 3-year follow-up results are consistent with neither HSIL or cancer.
