*P < 0.05 was considered statistically significant. DFS, disease-free survival; OS, overall survival; IMPC, invasive micropapillary carcinoma; IDC-NOS, invasive ductal carcinoma, non-special type; sLex, sialylated Lewis glycoprotein X; EMA, epithelial membrane antigen. P < 0.05, calculated with the log-rank test.
