Representative images of immunostaining for 9 molecular markers.A, Positive nuclear Ki67 staining. The Ki67 labeling index of this specimen is 12%. B, p53 staining in the nucleus. This tumor was scored as p53-positive. C, Positive HER2 membrane staining. The HER2 expression of this tumor was scored as 3+. D, Positive nuclear FOXA1 staining. This tumor was classified as FOXA1-positive. E, Positive nuclear GATA3 staining. This tumor was classified as GATA3-positive. F, Positive CK5/6 membrane or sub-membrane staining of tumor cells. This tumor was classified as CK5/6-positive. G, Positive CK14 membrane or sub-membrane staining of tumor cells. This tumor was classified as CK14-positive. H, Positive EGFR membrane staining of tumor cells. The EGFR expression of this tumor was scored as 3+. I, Positive P-cadherin membrane or sub-membrane immunoreactivity of tumor cells. This tumor was classified as P-cadherin-high. The magnification of all figures is ×400.
