Phagocytosis of IgG opsonized sheep erythrocytes (EA) by peripheral blood monocytes was evaluated in 73 individuals: 29 patients with malignant neoplastic diseases, 24 patients with non-malignant diseases and 20 normal donors. In a 30-min assay, phagocytosis values observed in 16 of 29 cancer patients and in 3 of 24 control patients were above the upper limit of the 2 S.D. interval for the normal donor population. The enhanced EA phagocytosis was dependent on a higher percentage of phagocytic cells as well as on an increased phagocytic rate. Mean values of phagocytosis obtained for cancer patients were statistically different (P <0.01) from those obtained for normal donors and control patients. According to a still limited number of observations, no association could be demonstrated between increased monocyte phagocytosis and histological type, anatomical site and clinical stage of the tumors.
