Abstract
PURPOSE: To determine the negative conversion regularity of high-risk human papillomavirus (HR-HPV) and to evaluate the prognostic implications of HR-HPV testing in patients with cervical cancer after treatment. METHODS: A retrospective post-treatment analysis of 173 patients with cervical cancer was performed from January 2011 to December 2012. Patients who had HR-HPV infection before treatment were included. Clinical and pathological characteristics, as well as follow-up information, were reviewed. RESULTS: The negative conversion rate of HR-HPV reached 68.9 % within half a year and increased most rapidly within the first 2 years after treatment. Univariate and multivariate analyses suggested that the negative conversion rate of HR-HPV was significantly correlated with clinical stage, treatment regimens, and HR-HPV type (P < 0.05). In our analysis of 173 patients, we found that HR-HPV status was predictive of 3-year survival rate and disease recurrence (P < 0.05). Pelvic recurrence, but not distant metastasis, was influenced by HR-HPV status (P < 0.05). Through 2 × 2 table analysis, we found that HR-HPV was more sensitive (71.43 %) and specific (94.20 %) than cervical cytology (sensitivity 62.86 % and specificity 78.26 %). CONCLUSIONS: The negative conversion rate of HR-HPV increased most rapidly within the first 2 years of cervical cancer surveillance. Persistent HPV infection was associated with a poor prognosis and had an impact on recurrence sites. Further large and multi-center prospective studies should be performed, but these results of this study suggested that HR-HPV monitoring is necessary to be used as a means of cervical cancer surveillance.
