[Carcino-embryonic antigen assay in cancer of the upper respiratory and digestive tracts].
Radioimmunological assay of carcino-embryonic antigen (CEA) was performed in 238 patients with cancer of the upper respiratory and digestive tracts after a minimum follow-up period of 3 years. Secretion of CEA was observed in only 1 out of 3 cases, levels, always being low and only slightly influenced by the localization or size of the tumor, and the condition of the lymph nodes. Initial levels are of no prognostic significance. The appearance of high levels during the course of the disease corresponds to shorter survival, but as it does not precede clinical evidence of recurrence or metastases this assay cannot play a role as a tumor marker.
