结直肠癌一级预防的研究进展

Progress in primary prevention of colorectal cancer

结直肠癌(colorectal cancer,CRC)是消化道常见恶性肿瘤之一,发生率及死亡率高.早期不易发现,当就诊时多数已属于晚期,治疗效果较差,预防CRC的发生尤为重要.近几年关于CRC预防的研究也在不断深入,结合最新国内外文献,本文将主要对CRC一级预防的研究进展做一总结.

Colorectal cancer（CRC） is one of the most common malignant tumors in the digestive tract, with high incidence and mortality. Most of CRC cases are diagnosed at the late stage, and the treatment effect is therefore poor. Thus, the prevention of CRC is particularly important. There have been many studies on the prevention of CRC in recent years. This paper will summarize the latest research on the primary prevention of CRC.
