Human telomerase reverse transcriptase (hTERT) and human nonmetastatic clone 23 (nm23-H1) may be separately involved in tumor progression of uterine cervix. We therefore investigate the correlations of hTERT and nm23-H1 in cervical carcinogenesis and further check their application. One hundred and twenty-eight cervical tissues, including 48 squamous cell carcinoma (SCC), 36 high-grade cervical intraepithelial neoplasia (CIN) (CIN 2 and CIN 3), 20 low-grade CIN 1, and 24 normal cases, were collected for immunohistochemical expression of hTERT and nm23-H1. Spearman rank correlation analysis was applied to assess their correlation in these samples. The Fisher exact or Chi-square test was used to evaluate the expression of hTERT or nm23-H1 among each subgroup. The sensitivity, specificity, positive and negative predictive values (PPV and NPV), and accuracy of hTERT and/or nm23-H1 were calculated for the prediction of high-grade CIN and SCC. We found normal cervix and CIN 1 samples had concurrent low expression of hTERT and nm23-H1, whereas high-grade CIN and SCC samples had concurrent high immunoreactivities. The hTERT alone and hTERT or nm23-H1 in combination had better sensitivity, NPV, and accuracy. The nm23-H1 alone as well as hTERT and nm23-H1 in combination had better specificity and PPV. Our results reveal a significantly positive relationship between expression of hTERT and nm23-H1 in normal and neoplastic tissues of uterine cervix. We suggest high expression of hTERT alone and hTERT or nm23-H1 in combination can be offered additional molecular information correlated with high-grade CIN and SCC.
