By immunohistochemical analysis, in tumor tissue, the median level of CD68+ cells/HPF was 49 (range, 25–87), the median level of CD163+ cells/HPF was 45 (range, 9–104), the median level of CD206+ cells/HPF was 7 (range, 3–37), and the median level of PU.1+ cells/HPF was 58 (range, 12–115). Here, SPI1 is linked to neoplasm.
