A new genetic blood test might pave the way for detecting early stage cancers that often prove fatal when caught too late. The test scans blood for DNA fragments released by cancerous tumors.
一項新型驗血技術或許可以發現早期癌癥，這些癌癥往往因發現太晚而導致患者死亡。該驗血能掃描出血液中癌性細胞釋放出來的DNA片段。
By reviewing these DNA fragments for mutations found in 58 "cancer-driver" genes, the blood test detects many early stage cancers without rendering false positives for healthy people. The test detected stage 1 or 2 colon, breast, lung or ovarian cancers between 59 percent and 71 percent of the time when assessing 200 patients previously diagnosed with cancer. The test also proved capable of screening out cancer-free people.
通過檢驗58種“致癌”基因中的突變DNA片段，這項驗血技術能夠檢測出很多早期癌癥，并且沒有誤診健康人士。在對200名已確診患有癌癥的人進行檢測時，它檢測出1期或2期結腸癌、乳腺癌、肺癌或卵巢癌的概率在59%到71%。這項技術還能夠篩選出無癌人士。
