美国研究人员发现从大便中可查出肿瘤细胞的突变基因,从而有希望进行简便准确的肠癌诊断试验。肠癌是世界上第三种最常见的癌,1992年仅美国就有6万多人死于这种疾病。虽然肠癌能通过手术治愈,但往往是确诊时已为肠癌晚期,因此约一半患者将会丧生。 U.S. researchers found that the mutant gene of tumor cells can be detected from the stool, so that a simple and accurate colorectal cancer diagnosis test is hopeful. Colorectal cancer is the third most common type of cancer in the world. In 1992 alone, more than 60,000 people in the United States died of this disease. Although bowel cancer can be cured by surgery, it is often diagnosed as having advanced cancer, so about half of the patients will die.
