A study on tissue carcinoembryonic antigen in colorectal carcinoma.

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...

Prognostic value of carcinoembryonic antigen distribution in tumor tissue of colorectal carcinoma.

CONTEXT Carcinoembryonic antigen (CEA) can be detected in colorectal tumor tissue but its role in the survival of patients remains controversial. OBJECTIVE To characterize the expression of tissue CEA using immunohistochemical staining in colorectal tumors and to analyze the relationship between this finding and preoperative plasmatic level of CEA, morphologic features and survival of patient...

Diagnostic value of carcinoembryonic antigen and carcinoma antigen 19-9 for colorectal carcinoma.

OBJECTIVE The purpose of this study was to evaluate the diagnostic efficiency of colorectal carcinoma (CRC) with the tumor markers Carcinoembryonic Antigen (CEA) and Carbohydrate Antigen 19-9 (CA 19-9), in addition to investigating whether CA 19-9 can be used to screen the disease process in patients with CRC who had no elevation of CEA levels. METHODS Serum levels of CEA and CA 19-9 were mea...

Carcinoembryonic antigen and recurrent colorectal cancer.

Roôle of carcinoembryonic antigen in bronchial carcinoma.

It has been reported that lung cancer patients often have raised carcinoembryonic antigen (CEA) levels but the significance of this in diagnosis and follow-up has yet to be established. The results of 256 preoperative investigations in patients with lung cancer are reported. Sequential values after radical surgery and chemotherapy and immunotherapy have been performed in 57 patients during trea...
