ABSTRACT
<p><b>OBJECTIVE</b>To investigate the associations of guanylate cyclase C (GC-C) mRNA and cytokeratin 20 (CK20) mRNA with metastasis and prognosis in early to moderate colorectal cancer patients.</p><p><b>METHODS</b>GC-C mRNA and CK 20 mRNA in peripheral blood of 74 colorectal cancer patients without distant metastasis were detected by fluorescent quantitative PCR (FQ-PCR). Based on their clinicopathological and postoperative follow-up data, the relationship and clinical significance of these data with metastasis hazards and prognosis factors were analyzed.</p><p><b>RESULTS</b>The positive rate of GC-C mRNA in 74 colorectal cancer patients was 33.8% (25/74), and CK20 mRNA was 31.1% (23/74). The 1-, 2-, 3- year disease-free survival rates of patients were 94.6%, 82.4% and 78.4% respectively. There were significant differences in positive rates of GC-C mRNA and CK20 mRNA, tumor differentiation, mesentery lymph node metastasis, tumor embolus in vessel and postoperative chemotherapy associated with 3-year disease free survival rate by Kaplan-Meier analysis (all P<0.05). While mesentery lymph node metastasis and tumor embolus in vessel were independent risk factors of 3-year disease-free survival (P<0.05). CK20 mRNA and tumor embolus in vessel were independent risk factors of 3-year disease-free survival by analysis stratified with clinical stage (P<0.05).</p><p><b>CONCLUSIONS</b>Detection of CK20 mRNA and GC-C mRNA in peripheral blood may be important for early detection of early metastasis of colorectal cancer.</p>
