摘要
结直肠癌已严重威胁人类的健康,2012年全世界约有136万结直肠癌新发病例,是世界第3高发恶性肿瘤,在世界男性发病排第3位,女性排第2位;死亡约69万例,居恶性肿瘤第4位。2010年我国结直肠癌新发病例数已超过27万,死亡病例13万以上。世界结直肠癌发病死亡比例均随时间而增加,且整体趋势为男性高于女性,发达地区高于欠发达地区,城市高于农村。在发达国家,90%以上患者年龄在50岁以上,但在发展中国家,患者发病年龄较小。本文以最新数据就世界结直肠癌流行病学现状作一综述,以期为今后结直肠癌的防治策略提供病因依据和理论支持。
Colorectal cancer has become a serious threat to human health. In 2012, there were about 1.36 million new cases of colorectal cancer, which was the third high incidence of malignant tumors in the world, ranking No. 3 in males and No. 2 in females; there were about 690 000 death cases, ranking No. 4 in malignant tumors. In china, the number of new cases of colorectal cancer had exceeded 270 000, and death more than 130 000 in 2010. The incidence and mortality of colorectal cancer in the world are increased with time, and the overall trend is higher in males than that in females, higher in developed regions than that in less developed regions, higher in urban areas than that in rural areas. In developed countries, the onset age of ≥90% patients is≥50 years old, but in developing countries the onset age is younger. This article reviews the latest data on the epidemiological status of colorectal cancer in the world, in order to provide the cause evidence and theoretical support for future control strategies of colorectal cancer.
