Detection of hepatic metastases from cancer of the breast

The liver scan and CEA assay were employed as a composite to increase the accuracy with which hepatic metastases from breast cancer may be detected. The number of false-positive interpretations was markedly reduced in this selected groups of patients. Other combinations of tests were examined and found less effective. In view of the potential benefits found in this study, it appears worthwhile to extend the principles applied here to other groups of patients at different stages of this disease and with other primary tumors.
