Abstract:
Objective To investigate the expression and clinical significance of plasma miR-150,squamous cell carcinoma anti gen (SCCA) and carbohydrate antigen 125 (CA125) in human papillomavirus (HPV) positive cervical cancer patients.Methods RT PCR was detected in 108 cases of HPV patients with positive cervical cancer (cervical cancer group) and 40 cases of HPV positive CIN patients (CIN group) and 40 cases of HPV with positive/HPV positive uterine benign lesions (control group),plasma miR-150,SCCA and CA125 levels.Analyzed the relation between miR 150 expression and clinicopathological features of cervical cancer.ROC curve was used to evaluate the early diagnostic value of miR-150,SCCA and CA125 in patients with HPV positive cervical cancer.Multivariate Logistic regression model was used to analyze the rela tionship between three indicators and HPV positive cervical cancer.Results The levels of miR-150,SCCA and CA125 in the cervical cancer group were significantly higher than those in the CIN group and the control group [miR-150(2-△△Ct):10.28 ±4.16 vs 4.72± 1.18 and 1.83±0.64.SCCA(ng/ml):9.86±2.14 vs 3.18±0.85 and 1.35±0.3t.CA125 (U/ml):46.26 ±11.58 vs 19.14±7.05 and 16.42±5.83,F=16.427,13.205,8.719,all P＜0.01].The expression of plasma miR 150 in HPV positive cervical cancer correlated with clinical stage,lymph node metastasis and depth of invasion (P＜0.05).The optimal cut-off values of plasma miR-150 for diagnosis of HPV positive cervical cancer and CIN were 8.25 and 3.46,and the sensitivity and specificity were 87.0 ％ and 84.3 ％,81.0 ％ and 80.2 ％,respectively.Logistic regression analysis showed that elevated plasma miR 150 and SCCA levels were independent risk factors for HPV positive cervical cancer [OR(95 ％ CI)=2.107(1.915～2.814),OR(95％CI)=1.583(1.327～2.036)].Conclusion Plasma miR 150 was significantly up regulated in patients with HPV positive cervical cancer,which can be used as a biological marker for the early diagnosis of HPV positive cervical cancer and the differential diagnosis of CIN.
