The results revealed that the relative expression levels of HER-2, CA15-3, CEA, SF, Vimentin and N-cadherin tumor marker mRNA were significantly higher in malignant CMTs than those in the benign and healthy groups (p < 0.05); however, there were no significant differences between the benign tumor group and the healthy control group (p > 0.05) (Table 6 and Figure 5). Here, ERBB2 is linked to neoplasm.
