To test this hypothesis, we analyzed CEA and CA19-9 serum levels in patients with advanced colorectal cancer who received cetuximab in combination with chemotherapy.
Carcinoembryonic antigen (CEACAM5, CEA) is a known tumor marker for colorectal cancer that localizes in a polarized manner to the apical surface in normal colon epithelial cells whereas in cancer cells it is present at both the apical and basolateral surfaces of the cells.
Effects of vitamin D and omega-3 fatty acids co-supplementation on inflammatory biomarkers, tumor marker CEA, and nutritional status in patients with colorectal cancer: a study protocol for a double blind randomized controlled trial.
Older age, male sex, African-American race, elevated CEA and not undergoing curative surgery were independent risk factors of cardiovascular mortality in patients with colorectal cancer.
In vivo, a murine surrogate of HERA-CD40L-stimulated clonal expansion of OT-I-specific murine CD8 T cells and showed single agent antitumor activity in the CD40 syngeneic MC38-CEA mouse model of colorectal cancer, suggesting an involvement of the immune system in controlling tumor growth.
The levels of APE1-AAbs, CEACAM-1 and CEA in the serum were measured, and the clinical value of each index in the diagnosis of colorectal cancer was analyzed.
Fecal C. symbiosum is a promising biomarker for early and noninvasive detection of colorectal cancer, being more effective than F. nucleatum, FIT and CEA.
Best performance was found for CEA in colorectal cancer (area under the curve=0.84, sensitivity=51.7% at 95% specificity vs. benign), CA19-9 in gallbladder/pancreatic cancer (AUC=0.85, sensitivity=60.6%) and AFP in liver cancer (AUC=0.87, sensitivity=68.4%).
The humanized anticarcinoembryonic antigen (anti-CEA) monoclonal antibody, labetuzumab, can be used as a tumor-targeting agent in colorectal cancer, since CEA is overexpressed in approximately 95% of colorectal cancer.
We compared the genome-wide transcriptomic profiles of CEA positive (MIP101 clone 8) and CEA negative (MIP 101) colorectal cancer cell lines with different metastatic potential in vivo.
Extended evaluation of a phase 1/2 trial on dosing, safety, immunogenicity, and overall survival after immunizations with an advanced-generation Ad5 [E1-, E2b-]-CEA(6D) vaccine in late-stage colorectal cancer.
The influence of CEA production by colorectal cancer cells on the function of E-cadherin junction complexes may explain the link between the elevated levels of CEA and the increase in soluble E-cadherin during the progression of colorectal cancer.
