The Stromal Tumor-Infiltrating Lymphocytes, Cancer Stemness, Epithelial-Mesenchymal Transition, and B7-H4 Expression in Ovarian Serous Carcinoma

The degree of stromal tumor-infiltrating lymphocytes was evaluated using hematoxylin and eosin-stained slides. Immunohistochemical analysis of B7-H4, CSC-related biomarkers, and epithelial-mesenchymal-transition-related biomarkers was performed using tissue microarray.
