<i>TP53, KRAS, APC</i>) has limited diagnostic sensitivity (40-60%), however, methylated DNA including <i>SEPT9, SFRP1, SDC2</i> can be applied with higher sensitivity (up to 90%) for CRC.Circulating miRNAs (e.g. miR-21, miR-92, miR-141) provide comparably high sensitivity for CRC as the circulating tumor cell mRNA markers (e.g.EGFR, CK19, CK20, CEA).
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.
Univariate and multivariate Cox survival analyses revealed that hnRNP AB expression and preoperative CEA levels were significant independent factors affecting overall survival in patients with CRC (P<0.05).
More importantly, the combination of lncRNAs shows more sensitivity in the detection of early-stage CRC than the combination of CEA and CA19-9, biomarkers currently used for CRC detection (p < 0.0001).
Further analysis showed that RP11-296E3.2 sensitivity and specificity in diagnosis of CRC metastasis is better than CEA in plasma (0.690 and 0.621, and 0.621 and 0.500, respectively), and the OS of metastatic CRC patients with higher LEF1-AS1 expression levels in tissues was short (log-rank p<0.05).
<b>Results:</b> We found that <i>LLNCRNA SNHG14</i>, hsa-miRNA-3940-5p and <i>NAP1L2</i> mRNA had an excellent performance characteristics and more superior than CEA, and CA19.9 for differentiating CRC from controls.
According to our prognostic model with 2 prognostic factors, the OS and DFS rate increased to 76.2% and 80.63%, respectively, in patients with high 18p TERRA expression and CEA levels ≤5 (P = .178, P = .057, respectively).18p TERRA expression was marginally significantly associated with preoperative CEA and significantly associated with telomere length, rendering it a potential prognostic factor for long-term oncologic outcomes in CRC.
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.
Univariate analysis revealed that tumor invasion depth, lymph node metastasis, metastasis, TNM stage, CEA, CA19-9, HA score and GPS had a significant association with the OS and DFS of CRC, furthermore HA score (<i>P</i><0.001, <i>P</i><0.001) TNM stage(<i>P</i><0.001, <i>P</i><0.001) were retained as the prognostic factors that were associated with OS and DFS according to multivariate analyses.
Both S100A9 and TNC levels were superior to CEA and CA19-9 levels as CRC diagnostic biomarkers; the combination of S100A9, TNC and CEA levels was an excellent biomarker with 79.8% sensitivity and 89.6% specificity.
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.
Survival analysis revealed that low expression of four of the ten genes, carcinoembryonic antigen related cell adhesion molecule 7 (CEACAM7), solute carrier family 4 member 4 (SLC4A4), glucagon (GCG) and chloride channel accessory 1 (CLCA1) genes, were associated with unfavorable prognosis in CRC.
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.
Receiver-operating characteristic (ROC) analysis indicated that combined detection of PCT and CEA appears to be a more effective marker to distinguish CRC patients from CA patients, with 70% sensitivity and 83% specificity.
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.
