Application Value of Detection of High-Risk HPV Infection in Early Cervical Cancer Patients in Disease Diagnosis and Prognosis Evaluation.

BACKGROUND

To analyze the relationship between HPV infection and early cervical cancer and postoperative survival outcomes.

METHODS

A total of 556 women were recruited to receive TCT and HPV tests from October 2017 to October 2018. The type of disease was pathologically diagnosed. The HPV positive rate, HPV-DNA, and E6/E7 mRNA quantitative level were detected, and the diagnostic accuracy of the subjects was analyzed by the receiver operating characteristic (ROC). The cervical intraepithelial neoplasia (CIN) and early cervical cancer patients were radically cured and followed up for 12.0 months to analyze the recurrence rate.

RESULTS

Seventy-two cases of chronic cervicitis, 54 cases of CIN, and 51 cases of cervical cancer patients were pathologically diagnosed (32 cases in early stage and 19 cases in middle and late stage). HPV positive rate increased gradually in chronic cervicitis, CIN, and cervical cancer group (p < 0.001) and HPV 16 + 18 subtype. The positive rate was significantly different (p = 0.009). HPV-DNA and E6/E7 mRNA quantification also showed significant differences (p < 0.001). ROC analysis indicated that the accuracy of HPV-DNA and E6/E7 mRNA quantitative diagnosis of malignant lesions (CIN+ cervical cancer) were 0.865 and 0.879, respectively. There were 4 cases (7.41%) of recurrence in CIN group and 5 cases (15.63%) in early cervical cancer group. There was no difference (p = 0.401) among all of the patients. All patients with recurrence were HPV positive.

CONCLUSIONS

HPV detection is an indispensable screening method for early cervical cancer and precancerous lesions, and comprehensive HPV 16 and 18 subtypes. DNA and E6/E7 mRNA quantification assay would further improve the accuracy of screening.
