Correlation analysis of serum CCAT2 relative expression with age, menopause, tumor size, FIGO stage, pathological type, SCC-Ag and the presence or absence of LNM in 180 primary CC patients showed that serum CCAT2 relative expression was positively correlated with tumor FIGO stage, SCC-Ag and LNM (all P < 0.05) (Table 1). Here, CCAT2 is linked to neoplasm.
