Molecular marker expression based on immunohistochemistry (×200). (A) Negative reaction is seen in rectal adenocarcinoma. (B) EGFR immunostaining shows a positive reaction in rectal adenocarcinoma, moderately-differentiated. (C) DAXX immunostaining shows a positive reaction in rectal adenocarcinoma, well-differentiated. (D) VEGF immunostaining shows a positive reaction in rectal adenocarcinoma, well-differentiated. (E) STAT3 immunostaining shows a positive reaction in rectal adenocarcinoma, mucinous type. (F) PD-L1 immunostaining shows a positive reaction in rectal adenocarcinoma, moderately-differentiated. DAXX = death-domain associated protein, EGFR = epidermal growth factor receptor, PD-L1 = programmed death-ligand 1, STAT3 = signal transducer and activator of transcription 3, VEGF = vascular endothelial growth factor.
