HSP110wt immunohistochemical staining of tissue microarray sections of 168 MSI-H colorectal cancers are semiquantitatively assessed. (a) A case showing the complete loss of HSP110wt expression is scored as 0. (b) A case showing weak staining of HSP110wt in tumor cells is scored as 1+. (c) A case showing intermediate staining of HSP110wt in tumor cells is scored as 2+. (d) A case showing strong staining of HSP110wt in tumor cells is scored as 3+.
