Further tumor sub-classification showed significant negative BCAR1/EREG correlations in AJCC stages I (rs = −0.3355; p = 0.0005), II (rs = −0.2045; p = 0.0024) and III (rs = −0.2951; p = 0.0001) whereas no correlation was observed in the advanced stage IV tumors (rs = −0.0672; p = 0.5411) (Figure 3E, Table S3A). Here, EREG is linked to neoplasm.
