Figure 1

Representative images showing hematoxylin-and-eosin-stained 4 μm sections of epithelial ovarian cancer (original magnification ×100). (a) Serous ovarian adenocarcinoma (G₂) of stroma-rich type (TSR ≥ 50%). (b) Serous ovarian adenocarcinoma (G₁) staining of stroma-poor type (TSR < 50%). (c) Serous ovarian adenocarcinoma (G₃) of stroma-rich type (TSR ≥ 50%). (d) Serous ovarian adenocarcinoma (G₃) of stroma-poor type (TSR < 50%). (e) Clear cell ovarian adenocarcinoma of stroma-rich type (TSR ≥ 50%). (f) Clear cell ovarian adenocarcinoma of stroma-poor type (TSR < 50%).
