Based on the significance of individual markers [25, 29, 35, 36], it is hypothesized that in non-metastatic GaC, cancers with negative expression of both markers may be relatively weak in both local growth and nodal metastasis capacities, cancers with positive Ki-67 expression but negative Her2 expression may have a stronger local growth potential, tumors with positive Her2 expression but negative Ki-67 expression may be more prone to invasion and nodal metastasis, and tumors with positive expression of both markers may be strong in both capacities. Here, MKI67 is linked to cancer.
