Immunohistochemical study of carcinoembryonic antigen in patients with colorectal cancer. Correlation with plasma carcinoembryonic antigen levels

Serum levels of carcinoembryonic antigen and a tumor-extracted carcinoembryonic antigen-related antigen in cancer patients.

Levels of carcinoembryonic antigen (CEA) and a tumor-extracted CEA-related antigen (TEX) were determined in sera from patients with carcinomas of the breast, colon, lung, head and neck, and a number of miscellaneous categories. The purpose of this study was to compare the levels of each antigen at various stages of malignant disease. Competitive radioimmunoassays developed in our laboratory wer...

Value of tissue carcinoembryonic antigen in patients with colorectal carcinoma.

The tumours of 55 patients with colorectal carcinoma were evaluated for tissue carcinoembryonic antigen (CEA) by immunoperoxidase staining. It was shown that 33/35 patients with increased preoperative serum CEA levels above 5 ng/ml had positive tissue CEA. The other 17/20 patients who had serum CEA levels less than 5 ng/ml could be demonstrated CEA in tissue. The results of tissues CEA were com...
