加利福尼亚大学圣地亚哥分校的一个研究小组发现了肝、肺、肾等10种不同人体组织的DNA模式。
It means cancer patients who have symptoms shared across different types of cancer, such as bloating or sudden weight loss, could in future be diagnosed quickly and easily without needing a biopsy to remove part of an organ for testing.
这意味着未来人们可以简单快速确诊出现腹胀、体重骤减等癌症一般症状的病患,而无需切除器官的一部分用来进行活组织检测。
Dr Catherine Pickworth, Cancer Research UK's science information officer, said: 'A biopsy can be invasive and unpleasant to go through, while any operation with an anaesthetic is risky.
英国癌症研究所科学信息主任凯瑟琳•皮克沃思博士称:“开刀进行活组织检测是有创的,而任何使用麻醉剂的手术都是有风险的。
This is potentially safer if it can be effective, which is why people are focusing on liquid biopsies.
如果血液检测有效,那么这种方法会更安全,这也正是人们关注血液活检的原因。
Finding new ways to detect and treat cancer at an early stage is vital to help more people survive the disease. Looking for the DNA of cancer cells in the blood is an exciting idea, and this encouraging new approach might help reveal the location of tumours. '
寻找在初期检测和治疗癌症的新方法对拯救更多的癌症患者至关重要。寻找血液中的癌细胞DNA是一个激动人心的想法,而且这种新方法可能有助于揭示肿瘤的位置。”
