We carried out the comparison of two prognostic models using Akaike information criterion (AIC), one of which was based on established cut-off of CD45-EpCAM-CK7/8-CD24+N-cadherin- CCs count; while the second model integrated clinicopathological parameters including tumor size, molecular subtype, age, lymph node involvement and neoadjuvant chemotherapy treatment. Here, KRT7 is linked to neoplasm.
