摘要:

目的 探讨循环胰岛素样生长因子-1(IGF-1)水平的变化在结直肠癌(CRC)进展中的临床意义。方法 采用化学发光免疫分析法检测经病理确诊的196例CRC患者及241名正常对照者循环IGF-1、癌胚抗原(CEA)和糖类抗原19-9(CA19-9)水平。结果 CRC组循环IGF-1水平[(143.86±55.07) ng/mL]明显高于正常对照组[(133.60±46.76) ng/mL](P<0.05)。正常对照组循环IGF-1水平表现为男性高于女性,并随年龄增加逐渐降低(P<0.05)。高循环IGF-1水平者CRC发生风险较高[比值比(OR)=1.72,95%可信区间(CI) 1.049~2.835,P<0.05]。CRC患者的循环IGF-1水平肿瘤长径≥5 cm组高于肿瘤长径<5 cm组,晚期(Ⅲ~Ⅳ)组高于早期Ⅰ期组和Ⅱ期组,低分化组高于高分化组和中分化组,有淋巴结转移组高于无淋巴结转移组(P<0.05)。循环CEA、CA19-9水平仅与肿瘤的病理分期有关。IGF-1联合CEA、CAl9-9检测的敏感性(58.16%)较单项检测(IGF-1 23.98%、CEA 32.22%和CA19-9 15.31%)显著提高(P<0.05)。结论 循环IGF-1是CRC的独立危险因素,与CRC的进展密切相关,对于CRC的预后评估有一定的临床意义。临床上IGF-1联合CEA、CA19-9可显著提高CRC检测的敏感性。

Abstract:

Objective To investigate circulating insulin-like growth factor-1(IGF-1) in the progression of colorectal cancer (CRC). Methods The levels of circulating IGF-1,carcinoembryonic antigen(CEA) and carbohydrate antigen 19-9 (CA19-9) were determined by chemiluminescence in 196 patients with CRC and 241 healthy controls. Results The level of circulating IGF-1 in CRC group [(143.86±55.07)ng/mL] was higher than that in healthy control group [(133.60±46.76)ng/mL](P<0.05). In healthy control group,the level of circulating IGF-1 in male group was higher than that in female group,which decreased with the increasing of age(P<0.05). The risk of CRC was high relatively in subjects with high circulating IGF-1 [odds ratio(OR)=1.72,95% confidence interval(CI) 1.049-2.835,P<0.05]. The level of circulating IGF-1 was higher in CRC group with tumor≥5 cm,at advanced stages(stage Ⅲ and stages Ⅳ),with low differentiation and with lymphoid node metastasis than those with tumor <5 cm,at early stages (stage Ⅰ and stage Ⅱ),with middle and high differentiation and without lymphoid node metastasis (P<0.05). The levels of CEA and CA19-9 were correlated to the pathological staging of tumor. The sensitivity of circulating IGF-1 combined determination with CEA and CA19-9 (58.16%)was higher than those of single items (23.98% for circulating IGF-1,32.22% for CEA and 15.31% for CA19-9)(P<0.05). Conclusions Circulating IGF-1 is an independent risk factor for CRC and plays an important role in the progression of CRC,and it has clinical significance for the prognosis evaluation of CRC. Circulating IGF-1 combined determination with CEA and CA19-9 could improve the determination sensitivity for CRC.
