通过活组织检测诊断癌症的方法十分痛苦且存在风险。近日,加利福尼亚大学圣地亚哥分校的研究人员发现,被癌症杀死的正常细胞会将DNA释放到血液中,这些DNA有其独特的特征。通过识别这些DNA信号,不用开刀就可以简单迅速地判断出肿瘤生长的位置。
A blood test for cancer can now show where in the body a tumour is growing, without the need for a painful biopsy.
一种癌症的血液检测方法可以测出肿瘤在体内生长的位置,而不需要进行活组织检测。
'Liquid biopsies' are hoped to revolutionise cancer treatment, by identifying people with slow-growing tumours and those most in danger. They work by detecting the DNA released by dying tumour cells.
人们希望通过“血液活检”发现人体内的慢性肿瘤和最危险的肿瘤,从而彻底改变癌症的治疗方式。其原理是检测死亡肿瘤细胞释放的DNA。
Now, for the first time, US scientists can also pinpoint the part of the body affected.
现在,美国科学家还首次实现精准定位患病的部位。
That is because the normal cells killed off by cancer also release DNA into the bloodstream, which has its own unique signature.
这是因为被癌症杀死的正常细胞也会将DNA释放到血液中,这些DNA有其独特的特征。
A team from the University of California San Diego have found the DNA patterns for 10 different types of tissue, including from the liver, lung and kidneys.
