摘要:

目的 探讨血清1-磷酸鞘氨醇(S1P)水平在结直肠癌早期诊断中的应用价值。方法 选取结直肠癌患者42例(结直肠癌组)、结直肠良性病变患者30例(良性病变组)、体检健康者38名(正常对照组)。收集结直肠癌组的临床病理资料,并检测所有研究对象血清S1P水平。采用受试者工作特征(ROC)曲线评估S1P、癌胚抗原(CEA)和糖类抗原19-9(CA19-9)单项和联合检测诊断结直肠癌的效能。结果 结直肠癌组血清S1P水平显著高于良性病变组和正常对照组(P<0.05、P<0.001),且Ⅰ~Ⅱ期结直肠癌组血清S1P水平显著高于Ⅲ~Ⅳ期结直肠癌组、良性病变组和正常对照组(P<0.05、P<0.05、P<0.001)。良性病变组血清S1P水平显著高于正常对照组(P<0.001)。有淋巴转移的结直肠癌患者血清S1P水平低于无淋巴转移患者(P<0.05),其他不同临床病理特征的结直肠癌患者之间血清S1P水平差异无统计学意义(P>0.05)。ROC曲线分析结果显示,以正常对照组为对照,血清S1P、CEA和CA19-9单项和联合检测诊断结直肠癌的曲线下面积(AUC)分别是0.924、0.701、0.579和0.943,诊断Ⅰ~Ⅱ期结直肠癌的AUC分别是0.944、0.663、0.611和0.955,诊断CEA和CA19-9单项或同时阴性结直肠癌的AUC分别为0.919、0.628、0.526和0.932。以良性病变组为对照,3项指标单项和联合检测鉴别诊断结直肠癌的AUC分别是0.655、0.720、0.582和0.787。结论 S1P或可作为诊断早期结直肠癌的生物标志物。

Abstract:

Objective To investigate the clinical role of serum sphingosine-1-phosphate(S1P) in the early diagnosis of colorectal cancer. Methods A total of 42 patients with colorectal cancer and 30 patients with colorectal benign lesions were enrolled. Totally,38 healthy subjects were enrolled as healthy control group. The clinicopathologic data of colorectal cancer group were collected. Serum S1P levels were determined. Receiver operating characteristic(ROC) curve was used to evaluate the diagnostic efficacy of S1P single and combined determinations with carcinoembryonic antigen(CEA) and carbohydrate antigen 19-9(CA19-9)in colorectal cancer. Results Serum S1P level in colorectal cancer group was higher than those in colorectal benign lesion group and healthy control group(P<0.05,P<0.001). Serum S1P level of stage Ⅰ to Ⅱ colorectal cancer group was higher than those of stage Ⅲ to Ⅳ colorectal cancer group,colorectal benign lesion group and healthy control group(P<0.05,P<0.05,P<0.001). Serum S1P level in colorectal benign lesion group was higher than that in healthy control group(P<0.001). Serum S1P levels in colorectal cancer patients with lymph metastasis were lower than those without lymph metastasis(P<0.05),but there was no statistical significance in serum S1P levels among patients with other clinicopathologic characteristics(P>0.05). ROC curve analysis results showed that,using healthy control group as control,the areas under curves(AUC) of serum S1P,CEA and CA19-9 for the diagnosis of colorectal cancer were 0.924,0.701,0.579 and 0.943,respectively. The AUC for the diagnosis of stage Ⅰ to Ⅱ colorectal cancer were 0.944,0.663,0.611 and 0.955,respectively,and the AUC for the diagnosis of single or simultaneous negative CEA and CA19-9 colorectal cancer were 0.919,0.628,0.526 and 0.932,respectively. Using colorectal benign lesion group as control,the AUC of the single and combined determinations of the 3 indicators were 0.655,0.720,0.582 and 0.787,respectively. Conclusions S1P may be a biomarker for the diagnosis of early colorectal cancer.
