In the total sample of both primary cancers, the positive correlation between the Sdc1 expression in the tumor epithelium with grade (P = 0.080) and the expression of the ERs (P = 0.068), as well as the positive correlation between the Sdc1 expression in the tumor stroma and the tumor size P = 0.063, was marginally significant (Table 4). Here, SDC1 is linked to neoplasm.
