A diagnostic model consisting of CCAT2 and LINC01133 has exhibited significant clinical utility for the identification of cervical intraepithelial neoplasia in both healthy individuals and patients. The serum concentrations of CCAT2, LINC01133 and LINC00511 could be used as effective non-invasive indicators for the diagnosis of CESC. The gene discussed is CCAT2; the disease is cervical squamous cell carcinoma.
