New Technique Promises Earlier Cancer Detection
A new technique could revolutionize the early detection of cancer, giving sufferers a greater chance of beating the disease, American scientists said. Researchers at the Massa-chusetts Institute of Technology have devised a novel method of 51 changes in the nucle-us of cells in the earliest states of the disease. More than 85 percent of all cancers origi-nate in the epithelium that lines the internal surfaces of organs 52 the body. Al-though these are treatable 53 they are diagnosed in one of the preventable stages, early body damages are almost 54 to detect, said scientist Feld. We present a new optical-probe technique based on light-scattering spectroscopy that is a-ble 55 detect pre-cancerous and early cancerous cells in cell-rich epithelia, he added in a statement.
The new technique relies on the fact 56 cell nuclei change in the early stages of can-cer and the differences scatter light in a characteristic way. Until now the changes were only de-tectable 57 a biopsy was taken, the scientists said. The new technique, 58 in the Sd-ence journal Nature , can be used in conjunction with a routine cancer screening and surveil-lance technique which uses an endoscope a flexible optical probe 59 with cam-eras which is inserted into a cavityin the bodyto check 60 cancers.
The scientists said they 61 their new technique in four different organs during rou-tine endoscopic cancer screening. The tip of the optical probe was brought into contact with the tissue to be tested and the scattering of light was recorded without the need for any tissue to be 62 , the scientists said. Our results show that light-scattering spectros-copy has the potential to detect pre-cancerous body damages and pre-invasive cancers throughout the body. This technique should 63 improve the efficiency of cancer screening and surveillance, the scientists said. Cancer is one of the biggest 64 in industrialized countries. 65 to figures from the World Health Organization, 10 million people were di-agnosed with the disease worldwide in 1997 and six million died.

新技術確保癌症的早期診斷
美國科學家說，一種新技術能夠使癌症的早期診斷髮生根本性的變化，能夠給患者更多機會戰勝疾病。麻省理工學院的研究者們發明了一種嶄新的方法用於檢測癌症最初期細胞核中的變化。百分之八十五以上的癌症起源於上皮，全身器官的內表面都被上皮所覆蓋。如果在可預防階段就得到診斷的話，這些癌症是可以治療的，儘管如此，早期的身體損害卻幾乎不可能檢測得出。科學家費爾德說。在一次聲明中他補充說：我們提出一種基於分光鏡檢查的新光學探子技術，這種新技術能夠在多細胞的上皮中檢測出癌變前的細胞和早期癌症細胞。
這項新技術的根據是：癌症早期細胞核會發生變化，而變化所產生的差異會使光線以一種特殊的方式散射。科學家們說，迄今為止，只有經過活檢之後才能檢測出這些變化。根據科學刊物《自然》中的描述，這種新技術可以與常規的癌症檢查和監測技術結合使用，常規技術是使用內窺鏡一種靈活的光學探子，上面裝有攝像頭，能插入體內的空腔來監測癌症的。
科學家們表示，在常規內窺鏡癌症檢測過程中，他們已經在四種不同的器官上試驗過這種新技術了。科學家們說，使光學探子的頂端和待檢驗的組織相接觸，並記錄下光的散射，無需切除任何組織。他們說：我們的結果表明，分光鏡檢查有潛力用於檢測癌症前期身體的損傷和全身尚未擴散的癌細胞。這種新技術將大大提高癌症檢查和監測的有效性。工業化國家，癌症是最大的殺手之一。根據世界衛生組織的數字，1997年全世界有1000萬人被診斷患有癌症，600萬人死於癌症
