Carcinoembryonic Antigen in Management of 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...

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...

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...

Carcinoembryonic antigen and recurrent colorectal cancer.

Role of carcinoembryonic antigen in detection of asymptomatic disseminated disease in colorectal carcinoma.

Fifty one patients were studied prospectively to evaluate the role of sequential determinations of the carcino-embryonic antigen concentration in the detection of asymptomatic disseminated disease after curative resection for colorectal carcinoma. Computed tomography of the liver was performed during the immediate postoperative period in all patients. Serum concentrations of the antigen were es...
