Correlation analysis of the IHC score with clinicopathologic parameters showed that YBX1 expression was correlated with Ki67 status (P = 0.037) and age (P = 0.041), but not tumor size (P = 0.162), E-cad status (P = 0.498) or lymph node metastasis status (P = 0.404) (Fig. 6, Table 1). Here, YBX1 is linked to neoplasm.
