Gain of human telomerase RNA gene is associated with progression of cervical intraepithelial neoplasia grade I or II.
The 3q26 chromosome region, where the human telomerase RNA gene (hTERC) is located, is a biomarker for cervical cancer and precancerous lesions. The aim of this study was to confirm the value of measuring hTERC gene gain in predicting the progression of cervical intraepithelial neoplasia grade I or II (CIN-I and -II, respectively) to CIN-III and cervical cancer. ⋯ In conclusion, measurement of hTERC gene gain in CIN-I or CIN-II patients using liquid-based cytological samples could be a useful biomarker to predict the progression of such cervical lesions. In addition, a 4:4 or N:≥5 signal ratio pattern may indicate the unlikeness of spontaneous regression of CIN-I or CIN-II lesions.
