As expected, the overall number of CD68+CD163− M1-type macrophages were rather low, with 0.9 cells/mm2 tumor near and 1.4 cells/mm2 tumor distant in the stromal compartment and 8.1 cells/mm2 and 6.0 cells/mm2 in the epithelial compartment of samples of the APBI studies. The gene discussed is CD68; the disease is neoplasm.
