Clinical evaluation of the macrophage electrophoretic mobility test for cancer.

Experience with the macrophage electrophoretic mobility (MEM) test of Field and Caspary in subjects with malignant and non-malignant disease is reported. There was some discrimination between groups of patients with benign and malignant lesions but there was no clear separation between the groups. A trial of the Cardiff modification of the test failed to discriminate between groups of patients with benign and malignant chest disease. In the view of the authors the MEM test in its present form is not sufficiently reproducible to warrant more general clinical application as an in vitro test for cancer.
