STAT3 and neoplasm: Immunohistochemical staining results for STAT3 and STAT5A represented in a semi-quantitative fashion as estimated percentage of tumor/lesional cells immunoreactive with the antibodies (0: no tumor/lesional cell staining, 1+: 1-25% of immunoreactive tumor/lesional cells, 2+: 26-50% of immunoreactive tumor/lesional cells, 3+: 51-100% of immunoreactive tumor/lesional cells) (expressed as number of cases)
