Further statistical analysis showed that MCAM expression was positive in three cases (15.79 %) among 19 cases of normal and benign tumour tissue, 21 cases (46.67 %) of malignant epithelial ovarian cancer showed positive expression among 45 cases examined, 6 cases (85.71 %) of borderline ovarian tumours showed positive expression among 7 cases examined, and 32 cases (80.00 %) of metastatic disease tissues showed positive expression among 40 cases examined. This evidence concerns the gene MCAM and metastatic neoplasm.
