Methods: 76 patients with colorectal cancer were collected in our department. They were divided into two groups, patients with metastases(MCRC,N=51) and patients after eradicative operation(non-metastasis group, NM,N=25).Serum markers of VEGF, OPN, CA19-9 and CEA were detected in all the included patients,and then to analyze the diagnostic value of the serum markers in detection of metastases.

测定76例结直肠癌患者（其中51例为转移性结直肠癌，25例为术后无转移者）血清中的VEGF、OPN和CA19-9及CEA水平，分析这些指标诊断结直肠癌转移的临床意义。
