<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在<span style="color: black;">将来</span>,这种检测<span style="color: black;">办法</span><span style="color: black;">能够</span><span style="color: black;">做为</span>常规筛查项目,使能够得到及早治疗的<span style="color: black;">病人</span>比例<span style="color: black;">明显</span><span style="color: black;">提高</span>,而不必等到癌症被传统筛查手段<span style="color: black;">发掘</span>的时候。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">美国约翰霍普金斯大学的肿瘤学教授Nickolas Papadopoulos是该<span style="color: black;">科研</span>的高级作者,他说:“<span style="color: black;">运用</span><span style="color: black;">选取</span>的生物标志物联合进行<span style="color: black;">初期</span>检测有可能改变我们筛查癌症的方式,它与利用多种<span style="color: black;">药品</span>的结合来治疗癌症的基本原理相同。<span style="color: black;">该检测还能够确定<span style="color: black;">病人</span>所患的癌症类型,这是以前癌症血液检测未能达到的<span style="color: black;">目的</span>。</span>”</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这项技术能够检测血液中自由漂浮的突变DNA,这些DNA由死亡的癌细胞释放到血液中。该测试筛选了在不同类型癌症中经常<span style="color: black;">出现</span>突变的16个基因,8种<span style="color: black;">和</span>已知蛋白质生物标志物进行测试。取决于肿瘤所处的身体部位不同,这些生物标志物<span style="color: black;">亦</span>被划分为不同的程度。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在对1005例<span style="color: black;">病人</span>血液样本的测试中,该技术对不同癌症的检测准确率在33%至98%之间。卵巢癌是最容易被检测到的,其次是肝癌、胃癌、胰腺癌、食道癌、结直肠癌、肺癌和乳腺癌。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">针对</span>5种<span style="color: black;">日前</span><span style="color: black;">无</span>筛查<span style="color: black;">办法</span>的癌症(卵巢癌、肝癌、胃癌、胰腺癌和食道癌),该技术的准确率在69%至98%之间。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">当该技术在对812名健康受试者进行测试时,只产生了7例的假阳性结果。美国约翰霍普金斯大学的肿瘤学教授Kenneth Kinzler是<span style="color: black;">科研</span>人员之一,他说:“高特异性是非常必要的,<span style="color: black;">由于</span>假阳性结果可能会使<span style="color: black;">病人</span>遭受不必要的有创性后续<span style="color: black;">检测</span>以确定癌症<span style="color: black;">是不是</span>存在。”</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">接受<span style="color: black;">实验</span>的<span style="color: black;">病人</span>都<span style="color: black;">处在</span>非转移期的癌症一期至三期<span style="color: black;">周期</span>。专家们指出,<span style="color: black;">初期</span>癌症的检测率非常低,而<span style="color: black;">针对</span><span style="color: black;">无</span><span style="color: black;">显现</span>任何症状的<span style="color: black;">病人</span><span style="color: black;">来讲</span>,检测率则更低。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">英国剑桥大学癌症流行病学教授Paul Pharoah说:“关于该<span style="color: black;">科研</span>存在<span style="color: black;">有些</span>说明。<span style="color: black;">首要</span>,80%的被检测的癌症都<span style="color: black;">处在</span>二期或三期的,而这<span style="color: black;">已然</span>是比较晚期了。证明一种检测技术能够检测到晚期癌症并不<span style="color: black;">寓意</span>着它在检测<span style="color: black;">初期</span>症状癌症中<span style="color: black;">一样</span>有用,更<span style="color: black;">不消</span>说是还<span style="color: black;">无</span><span style="color: black;">显现</span>症状的癌症了。该技术对一期癌症的<span style="color: black;">敏锐</span>度<span style="color: black;">仅有</span>40%。”</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">英国伦敦大学学院癌症<span style="color: black;">科研</span>所的Chris Abbosh认为该<span style="color: black;">科研</span>非常令人兴奋。他说:“这项<span style="color: black;">科研</span>首次将蛋白质生物标志物和血液中的肿瘤DNA结合起来<span style="color: black;">做为</span>癌症的筛查<span style="color: black;">工具</span>,并将该<span style="color: black;">工具</span>在<span style="color: black;">海量</span>不同癌症的<span style="color: black;">病人</span>中进行了应用。”</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">尽管<span style="color: black;">日前</span>的测试<span style="color: black;">办法</span><span style="color: black;">没</span>法准确检测所有的癌症,<span style="color: black;">然则</span>它能够检测到<span style="color: black;">非常多</span><span style="color: black;">本来</span>可能<span style="color: black;">没</span>法被检测到的癌症。约翰霍普金斯大学的肿瘤学教授Bert Vogelstein说:“<span style="color: black;">日前</span><span style="color: black;">咱们</span><span style="color: black;">持有</span>的最有效的癌症治疗<span style="color: black;">办法</span>只能使一小部分癌症<span style="color: black;">病人</span>受益,<span style="color: black;">咱们</span><span style="color: black;">已然</span>认为这是很大的突破了。<span style="color: black;">倘若</span><span style="color: black;">咱们</span>想在<span style="color: black;">初期</span>癌症检测中取得<span style="color: black;">发展</span>,就<span style="color: black;">必要</span><span style="color: black;">起始</span>更加现实地正视这个问题,即<span style="color: black;">无</span>测试<span style="color: black;">办法</span>能够检测出所有的癌症。”</p>
