Two antigens cross-reactive with carc inoembryonic antigen (CEA) and distinct from the nonspecif ic cross-react ing antigen were identified in meconium by double immunodiffusion with a conventional goat ant i -CEA antiserum. These two antigens together competi t ively inhibited cross-react ing antibodies against them in CEA radioimmunoassay and contr ibuted to the measurement of meconium CEA le...

INTRODUCTION To explore the influence of glycemic levels on the serum carcinoembryonic antigen (CEA) levels in patients with diabetes. METHODS This is a cross-sectional study. Patients with diabetes aged 18-75 years old were recruited. Those patients with carcinoma, abnormal renal function (serum creatinine ≥ 115 μmol/l), and abnormal hepatic function (serum alanine aminotransferase ≥ 97.5 U/...

In an attempt to elucidate the tumor properties relating to responsiveness to chemotherapy, we examined immunohistochemically the expression of P-glycoprotein (P-gp) and carcinoembryonic antigen (CEA) in small cell lung cancer (SCLC) tumors. Tumor specimens from 33 patients were obtained at the time of diagnosis and relapse. Four patients expressed P-gp in their initial tumors, and 7 others did...

We report the case of a 38-year-old man, who developed cutaneous metastases in the left inguinal groove 15 years after curative gastrectomy for advanced gastric adenocarcinoma. Histopathologic examination revealed poorly differentiated adenocarcinoma cells. They were stained positive for villin, CDX-2, CKpan (AE1/ AE3), CEA, CK8/18, CK19, CK7, EMA, Ki-67 (50%), and negative for S-100, CK20, CD3...

We have previously reported the development of a recombinant vaccinia virus vaccine expressing the human carcinoembryonic antigen (CEA) gene, designated rV(NYC)-CEA. This construct has been shown to elicit specific anti-CEA immune responses and an antitumor effect in a murine tumor model. In the studies reported here, the safety and immunogenicity of this recombinant vaccinia virus were evaluat...

BACKGROUND Carcinoembryonic antigen (CEA) is one of the most widely used tumor markers and is increased in 30%-60% of patients with pancreatic cancer. Although carbohydrate antigen 19-9 (CA19-9) is the most important serum biomarker in pancreatic cancer, the diagnostic and prognostic value of CEA is gradually being recognized. MATERIALS AND METHODS The MEDLINE, EMBASE, and Web of Science data...
