iagnostic value of HPV L1 capsid protein combined with HR-HPV typing and TCT for cervical precancerous lesions and cervical cancer

Objective? To explore the diagnostic value of human papilloma virus L1 (HPV L1) capsid protein combined with high-risk HPV (HR-HPV) typing and thinprep cytology test (TCT) for cervical precancerous lesions and cervical cancer. Methods?1 094 women who received cervical cancer screening were selected as the research subjects, and were grouped based on histopathological results. The expression level of HPV L1 capsid protein, and positive rates of HR-HPV and TCT were compared between the groups. Results?There was a significant difference between TCT positive rate and HR-HPV positive rate (P<0.05). Histopathological examination found 179 normal cases or cases only with inflammation (control group), 26 cases of CIN gradeⅠ (CIN1 group), 44 cases of CIN gradeⅡ (CIN2 group), 40 cases of CIN gradeⅢ (CIN3 group) and 21 cases of cervical cancer (cervical cancer group). The positive rates of TCT and HR-HPV in cervical cancer group were the highest, and the expression level of HPV L1 capsid protein was the lowest (P<0.05). The AUC values of HPV L1 capsid protein combined with HPV typing and TCT to diagnose cervical precancerous lesions and cervical cancer were 0.897 and 0.804, respectively (P<0.05). Conclusion?HPV L1 capsid protein, HPV typing and TCT are of clinical value in the diagnosis of cervical precancerous lesions and cervical cancer.
