Globally, cervical cancer is the second most common cancer among women, and determining potential targets involved in tumor progression is necessary. This study investigated the clinic-pathological significance of twist homolog 2 (TWIST2), a basic helix-loop-helix transcription factor, and correlated TWIST2 and E-cadherin expression in cervical cancer.


A series of 142 samples, including 14 cases of normal cervical tissues, 58 cases of cervical intraepithelial neoplasia (CIN) and 70 cases of squamous cell carcinoma (SCC), were examined TWIST2 and E-cadherin immunohistochemical staining and statistical analysis.


Increased cytoplasmic and nuclear expression levels of TWIST2 were associated with the malignant transformation of cervical epithelium and the histological progression of cervical cancer. A logistic test showed that TWIST2 was a relatively independent predictor of lymph node metastasis of SCC. Further, increased levels of TWIST2 were also associated with aberrant expression of E-cadherin, an important EMT indicator.


The present data suggest that TWIST2 overexpression was significantly linked to cervical cancer progression, which makes it a promising marker for determining the metastatic potential of cervical cancer, and up-regulation of TWIST2, in combination with aberrant E-cadherin expression in primary cervical cancer tissues, may predict the malignant transformation and distal metastasis of carcinomas.
