Representative cases with high and low CD73 expression. A A preoperative CT image of a CD73^High CRLM (arrow) in the right hemiliver. B A preoperative CT image of a CD73^Low CRLM (arrow) in the left hemiliver. C, D Representative tissue microarray cores of the high C and low D CD73 expression of the respective CRLM. Hematoxylin and eosin staining (left) shows the integrity and general architecture of the tissue. Immunofluorescent staining (right) shows cell nucleus (blue, DAPI), CD73 expression (red), and the cancer cells with the pan-cytokeratins epithelial cell marker (green). Scale bars represent 100 µm
