Radioimmunoassay for carcinoembryonic antigen and alpha 1-fetoprotein in the qualitative evaluation of focal hepatic lesions in Japan.

摘要: The combined tests of serum alpha1-fetoprotein (AFP) and carcinoembryonic antigen (CEA) were routinely performed in 210 patients with focal hepatic lesions on a 99mTc-colloid liver scan order to determine whether these could provide more useful information that AFP test alone the qualitative evaluation lesions. predictive value hepatoma positive remained 80%. However, when negative CEA was AFP, (91%) both greatly increased. On other hand, metastatic cancer showed 92%.
