[Immunohistochemical study of the localization and distributional patterns of CA 19-9 and CEA in primary and metastatic nodal lesions of gastrointestinal cancer].
The localized and distributional patterns of CA 19-9 and CEA have been immunohistochemically examined in 22 nodal metastasis from antigen-producing gastrointestinal cancers. CA 19-9 and CEA were found in 95% and 45% of these metastasis respectively. The same distributional and localized patterns in the metastasis as were found in the primary lesions amounted to 77% and 41% for CA 19-9, and 45% and 27% for CEA, respectively. These results suggest that the capability of producing CEA is absent or suppressed in the metastatic lesions, whereas the capability lesion but also in the metastatic lesions as well.
