Methods: The surgical treatment of HSIL patients from January 2013 to January 2015 in our hospital were selected. All patients were routinely tested for HPV and P16 protein, All patients were followed up for 1 year. Patients were divided into progressive group and quiescent group according to whether the disease progressed one year after surgery. Preoperative HPV and P16 protein levels were compared between the two groups. Using receiver operating curve (ROC curve) Analysis of HPV diagnostic value of HSIL. The levels of HPV and P16 protein in the two groups were analyzed and compared. Results: The quantitative level of high-risk HPV-DNA after LEEP was significantly lower than that before operation. The level of P16 protein in preoperative patients was higher than that before operation, and the difference was statistically significant. There were 21 patients in the postoperative progression group, and the average HPV-DNA content in the patients in the progression group was higher than that in the control group within one year after operation. The difference was statistically significant. The P16 protein level in patients in advanced group was significantly higher than that in resting group. Preoperative HPV-DNA levels and P16 protein levels in patients with progressive disease were significantly higher than those in still group. ROC curve analysis showed that the cut-off value of 2.441, HPV-DNA prediction of HSIL patients one year after the recurrence of the sensitivity was 95.12%, the specificity was 76.16%, under the curve area of 0.878;7.4 cut-off value, P16 The predictive value of HSIL patients recurrence after 1 year was 71.95%, specificity was 66.67%, and the area under the curve was 0.753. The recurrence group HPV-DNA content and P16 protein level showed a significant positive correlation, with statistical significance. Conclusions: LEEP can reduce the postoperative levels of HPV and P16 protein in patients with HSIL. The HPV and P16 protein levels are of high value for the early diagnosis of HSIL and the prediction of postoperative disease progression.展开更多
