Abstract:

目的　综合评价血清胰岛素样生长因子 1(IGF- 1)、胰岛素样生长因子结合蛋白 3(IGFBP -3)水平和大肠癌的关系。方法　利用Meta分析法对 6篇关于血清IGF- 1、IGFBP- 3水平与大肠癌关系的研究文献进行定量综合分析。结果　对于IGF 1,合并OR =1.5 6 (95 %CI:1.14～ 2 .13);按实验方法不同分层,间接酶联免疫吸附试验 (ELISA)合并OR =1.92 (95 %CI:1.2 6～ 2 .93),IRMA法合并OR =1.2 3(95 %CI:0 .78～ 1.94 );对于IGFBP 3,合并OR =0 .78(95 %CI:0 .4 3～ 1.4 4 );按实验方法不同分层,ELISA法合并OR =0 .4 6 (95 %CI:0 .2 9～ 0 .74 ),免疫放射测定法 (IRMA)合并OR =1.4 4 (95 %CI:0 .93～ 2 .2 3)。结论　血清IGF -1高水平为大肠癌的独立危险因子,IGFBP- 3与大肠癌的关联不具有统计学意义;IGFBP -3与大肠癌关系的各研究之间异质性是由实验方法不同而引起,但该结论尚需大样本并同时进行两种方法的测量证实。

English Abstract:

Objective To evaluate the relationship between circulating levels of insulin-like growth factor-1(IGF-1),IGF-binding protein-3(IGFBP-3) and colorectal cancer. Methods A meta-analysis of 6 epidemiological studies on insulin-like growth factors and risk of colorectal cancer were performed. Results The pooled odds ratio( OR ) of IGF-1 and IGFBP-3 were 1.56 (95% CI : 1.14- 2.13 ) and 0.78 (95% CI : 0.43- 1.44 ) respectively. According to the results from different measurements(enzyme-linked immunoabsorbent assay and immunoradiometric assay),the pooled OR were 1.92 and 1.23 for IGF-1, 0.46 and 1.44 for IGFBP-3 respectively. Conclusion High serum levels of IGF-1 were independent risk factors of colorectal cancer but the OR of IGFBP-3 was not statistically significant. The heterogeneity between studies on IGFBP-3 and colorectal cancer was caused by different measurements used,but there was still a need to conduct simultaneous large size study under 2 different measurements for further conclusion.
