Objective To explore the diagnostic value of HR -HPV combined with TCT in the diagnosis of cervical cancer and precancerous lesion.Methods 1 198 cervical specimens were selected for the study.The results of HR -HPV detection and TCT detection were analyzed,with the pathological results as the gold standard,the diag-nostic value of HR -HPV and TCT in the diagnosis of cervical cancer and precancerous lesion were discussed. Results With increasing pathological grade,TCT positive rate increased gradually,there was a correlation between them(r =0.629,P <0.05).With increasing pathological grade,HR -HPV positive rate increased gradually,there was a correlation between them(r =0.684,P <0.05).The sensitivity of HR -HPV combined with TCT in the differ-ential diagnosis of cervical cancer,precancerous lesions was 100.00%,specificity was 79.64%,missed diagnosis rate was 0.00%,the misdiagnosis rate was 20.36%.Conclusion HR -HPV combined with TCT examination has high clinical value in the diagnosis of cervical cancer and precancerous lesions.
