Summary HER2 and Ang-2 immunohistochemical staining in tumor tissue sample from 66 cases of primary breast cancer

HER2+HER2−Total
Ang-2+15 (R = 0.38182, P < 0.005)14 (R = −0.38182, P < 0.005)29
Ang-2−1 (R = −0.38182, P < 0.005)36 (R = 0.38182, P < 0.005)37

  • NOTE: The nonparametric Spearman's rank correlation was used to analyze for significance of the relationship between HER2 expression and Ang-2 expression (P < 0.005).
