Figure S1. Immunohistochemical staining results. The tumor showed a wild-type p53 pattern (A, × 200) and exhibited strong cytoplasmic expression of β-catenin (B, × 200). Some tumor cells exhibited weak membranous expression of EGFR (C, × 200). The tumor was negative for Bcl-2 (D, × 200). The tumor shows membrane and cytoplasmic immunopositivity for EMA (E, × 200) and negative for S-100 protein (F, × 200). Vimentin is diffusely expressed in the cytoplasm of tumor cells (G, × 200). The Ki-67 proliferation index is estimated to be approximately 15% (H, × 200). Scale bar = 100 μm. (DOCX 8214 kb) |
