Stratifying clinical characteristics by the two MAGE-A9 expression groups, we observed that MAGE-A9 protein positivity was significantly associated with FIGO stage (P = 0.001), tumor grade (P = 0.042), level of CA-125 (P = 0.026) and metastasis (P = 0.014) (Table 2). Here, MAGEA9 is linked to neoplasm.
