摘要 随着近年来生活习惯与饮食结构的改变,我国大肠癌的发病率明显升高。虽然通过内镜下早期筛查和摘除大肠腺瘤样息肉的方式可减少部分大肠癌的发生,但限于广大农村地区的医疗条件和患者的依从性等问题,无法普及应用,且摘除息肉后的复发率仍高达40%~50%。尽管阿司匹林和COX-2抑制剂有一定疗效,但因其药物副反应和费用高昂而使用受限。因此,如何更有效地预防大肠癌仍是医学科学工作者关注的热点。丁酸盐特别是丁酸钠属短链脂肪酸(shortchain fattyacid,SCFA),为膳食纤维在肠道内分解的产物,其在预防大肠癌发生发展中的作用已为很多学者重视。现就丁酸盐的生物学特性、其预防大肠癌的可能机制、研究进展与存在的问题做一系统阐述。
