Abstract:
BACKGROUND:In order to develop a multi-marker RT-PCR, which as such may be more sensitive than a single marker assay for the detection of disseminated tumor cells, we evaluated six RT-PCR markers: cytokeratin 20 (CK20), carcinoembryonic antigen (CEA), guanylyl cyclase C (GCC), epidermal growth factor receptor (EGFR), matrilysin (MMP-7) and HeLa metastatic gene (HLM). MATERIALS AND METHODS:The expression was studied in human colon tumor cell lines, in colon cancer tissues, and in blood and/or bone marrow samples of colorectal cancer patients and control subjects. RESULTS:The cell lines showed a differential expression pattern. The expression of all markers was detected in control blood samples with the lowest frequency for CK20 and EGFR. Semiquantitative analysis, which was performed to study threshold setting, demonstrated that GCC expression was elevated in patient compared to control samples. However, the reproducibility was questionable. CONCLUSION:The results presented in this study suggest an enhanced sensitivity for a combination of RT-PCR markers. Due to limited specificity however, the development of a multi-marker RT-PCR by using conventional PCR does not seem feasible. Future studies should focus on the potential of quantitative RT-PCR.
