Abstract

Abstract In five out of eight patients operated on for mammary carcinoma, an extract of the autologous tumour induced inhibition of the in vitro leukocyte migration. Extracts of the patient's normal mammary tissue gave no inhibition, and negative results were likewise obtained when leukocytes from matched controls were exposed to extracts of isogeneic normal or tumourous tissue. These observations suggest that in some patients mammary carcinoma is associated with a state of cellular hypersensitivity against components of the tumour.
