[Sensitivity and specificity of CEA, Ca 15-3 and MCA levels in visceral breast carcinoma metastasis].

The determination of mucin like carcinoma associated antigen (MCA) showed a sensitivity of 72% in visceral metastasis of breast cancer, of 25% in metastasis of stomach cancer and of 10.3% in metastasis of colorectal cancer. The sensitivity of CA 15-3 was 83% (n.s.) in metastasis of breast cancer, that of CEA was 29% (p less than 0.05). The sensitivity of isolated metastasis and isolated invasion of the lymph nodes was under 20% for MCA, CA 15-3 and CEA.
