title: Alteration in monocyte function in patients with breast cancer.
abstract: Migration, phagocytosis and lysozyme production of peripheral monocytes from 36 patients with breast carcinoma was compared with a group of 36 healthy controls. A significant reduction in monocyte random migration and migration towards a chemotactic agent (P less than 0.001) was observed in patients with breast cancer. Furthermore monocyte phagocytic activity was also significantly decreased (P less than 0.001) in breast cancer patients compared to the controls. In contrast lysozyme production by peripheral monocytes was significantly increased in patients with breast cancer compared to controls (P less than 0.001). The changes in monocyte function in patients with breast carcinoma were not due to abnormal blood biochemistry or to direct continuous serum inhibitors, suggesting that the defect may be intrinsic. This defect in monocyte function may play an important role in the control of malignancies by cellular immune processes.
