Advantages of the AMDL-ELISA DR-70 (FDP) Assay over Carcinoembryonic Antigen (CEA) for Monitoring Colorectal Cancer Patients
نویسندگان
چکیده
The DR-70 (FDP) test was the first cancer test cleared by USFDA for monitoring colorectal cancer (CRC) since Carcinoembryonic Antigen (CEA) in 1982. Conservatively, 50% of biopsy-positive CRC patients have negative CEA values. DR-70 and CEA values were compared for 113 CRC monitoring patients. Total concordance rates for DR-70 and CEA were 0.665 and 0.686, respectively. CRC patient pairs were grouped based on their CEA value to deduce DR-70's effectiveness at monitoring patients with low CEA values. DR-70 had 12% to 100% greater positive concordance rates than CEA in this group. DR-70 is a welcome new option for CRC patients.

CEA Plasmid as Therapeutic DNA Vaccination against Colorectal Cancer
Background: Human colorectal cancer cells overexpress carcinoembryonic antigen (CEA). CEA is a glycoprotein which has shown to be a promising vaccine target for immunotherapy against colorectal cancer. Objective: To design a DNA vaccine harboring CEA antigen and evaluate its effect on inducing immunity against colorectal cancer cells in tumor bearing mice. <str...
متن کاملEvaluation of the Relationship between Peroxisome Proliferator Receptors (PPARα, PPARγ, and PPARδ) Expression and Carcinoembryonic Antigen (CEA) in Patients with Colorectal Cancer
Introduction: Studies have shown that an increase in carcinoembryonic antigen (CEA) is associated with the progression of colorectal cancer and is considered a sensitive diagnostic factor for CRC. Moreover, the role of peroxisome proliferators (PPARs) has recently been considered in colorectal cancer. This study aimed to investigate the relationship between the expression level of PPARs and CEA...
متن کاملCarcinoembryonic Antigen Expression and Resistance to Radiation-and 5-Fluorouracil-Induced Apoptosis and Autophagy
Understanding the mechanism of tumor resistance is critical for cancer therapy. In this study, we investigated the effect of carcinoembryonic antigen (CEA) overexpression on UV-and 5-fluorouracil (5-FU)-induced apoptosis and autophagy in colorectal cancer cells. We used histone deacetylase (HDAC) inhibitor, NaB and DNA demethylating agent, 5- azacytidine (5-AZA) to induce CEA expression in HT29...
