Characterization of human epidermal growth factor receptor 2 (HER2) expression in serous cystadenoma, serous borderline tumor , low-grade serous ovarian carcinoma, and high-grade serous ovarian carcinoma patients. (A) Representative histological images of Hematoxylin-Eosin staining and HER2 staining. Scale bars: 50 μM. (B) HER2 expression ratio in the serous ovarian tumor patients. Comparisons were performed using the Chi-squared test. P < .05 was considered statistically significant. HGSC = high-grade serous ovarian carcinoma, LGSC = low-grade serous ovarian carcinoma, SBT = serous borderline tumor.
