Objective To investigate the clinical value of soluble CD40 ligand(sCD40L) in the early diagnosis of patients with colorectal cancer and their prognostic assessment. Methods The serum s CD40 L and carcinoembryonic antigen(CEA) concentration were detected by Luminex x MAP analysis and ELFA method in 78 patients with colorectal cancer and 95 healthy control people.ROC curve was used to make comparison between the clinical value of s CD40 L and CEA in the diagnosis of colorectal cancer. Those patients with colorectal cancer were divided into s CD40 L high expression group(sCD40Lhigh) and s CD40 L low expression group(sCD40Llow). Analysis was made in the correlation between serum s CD40 L level and clinical pathological parameters. Kaplan-Meier survival curve was used to analyze the effects of s CD40 L expression level on patients' prognosis. Results The serum s CD40 L concentration of patients with colorectal cancer was significantly higher than that of healthy controls. ROC curve showed that the specificity and sensitivity of s CD40 L in the diagnosis and prognosis of colorectal cancer was superior to those of CEA, and the AUC value of s CD40 L was larger than that of CEA. The concentration of serum s CD40 L was closely correlated with lymph node metastasis,the depth of tumor invasion, and TNM staging. The survival time of patients with high s CD40 L expression level was significantly shorter than that of those in the low expression group. Reexamination showed the significant decreasing of serum s CD40 L concentration in 15 cases one year after the operation. Conclusion SCD40 L has certain value in the evaluation of the early diagnosis and prognosis of patients with colorectal cancer.
