Methods: The expression level was detected by nested RT-PCR in 20 healthy people, 20 patients with colorectal adenoma and 90 cases of patients with colorectal cancer disease peripheral blood CK19 mRNA and MUC-1 mRNA. Results: The positive expression rate of CK19 mRNA and MUC-1 mRNA were: 58.89%(53/90) and 52.22%(47/90). No CK19 mRNA healthy people 20 cases in the control group in the peripheral blood, the expression of MUC-1 mRNA in 12 cases, the expression rate of 60%(12/20). In 20 cases of colorectal adenoma diseases have the expression of CK19 mRNA in 1 cases, the expression rate of 5%(1/20), the expression of MUC-1 mRNA in 10 cases, the expression rate of 50%. Patients with colorectal cancer CK19 mRNA, MUC-1 mRNA expression rate was significantly correlated with tumor staging, the degree of differentiation of the tumor cells and tumor metastasis(P < 0.05). Conclusion: Marker CK19 mRNA as the detection of micro-metastasis in peripheral blood of patients with colorectal cancer has good sensitivity and specificity, but CK19 mRNA, MUC-1 mRNA can be used to judge the prognosis of patients with colorectal cancer index.展开更多
