Abstract:
OBJECTIVE:To investigate the expression of claudin 4 (CLDN4) in cervical tissues from patients with different cervical lesions, and to explore the value of combined detection of CLDN4 and high risk human papilloma virus (HR-HPV).
METHODS:The cervical tissue specimens of low-grade squamous intraepithelial lesion (LSIL, =30), high-grade squamous intraepithelial lesion (HSIL, =30), squamous cell carcinoma (SCC, =30) as well as chronic cervicitis (control, =30) were collected from the Sir Run Run Shaw Hospital of Zhejiang University during June 2015 and December 2016. The expression of CLDN4 protein in tissue specimens was detected by immunohistochemistry, HR-HPV was detected by real-time quantitative PCR, and the cervical exfoliated cells were examined by thinprep cytologic test (TCT). The ROC curve was applied to analyze the diagnostic value of TCT combined with HR-HPV and CLDN4 combined with HR-HPV tests for HSIL and SCC of the cervix.
RESULTS:With the increase of the severity of cervical lesions, the positive rate of CLDN4 expression rose (=0.832, <0.05). Positivity of both HR-HPV infection and CLDN4 expression was found mainly in the HSIL and SCC groups. The areas under curve (AUC) of TCT combined with HR-HPV and CLDN4 combined with HR-HPV tests for diagnosis of HSIL and SCC were 0.683 and 0.633, respectively; the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of TCT combined with HR-HPV test for diagnosis of HSIL and SCC were 100.0%, 36.7%, 61.2%, 100.0% and 46.7% respectively; those of CLDN4 combined with HR-HPV test were 96.7%, 30.0%, 58.0%, 90.0% and 55.0%, respectively.
CONCLUSIONS:CLDN4 expression may be related to the occurrence and development of cervical carcinoma and precancerous lesions. CLDN4 combined with HR-HPV test may be used for diagnosis of HSIL and SCC of the cervix clinically.
