一滴血可“揪出”8种初期癌症,一查一个准!意见40岁后每年都查
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">任何肿瘤都是早<span style="color: black;">发掘</span>、早治疗、早治愈。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">癌症<span style="color: black;">初期</span>治疗简单,<span style="color: black;">经过</span>手术或放疗这种局部治疗就够了,<span style="color: black;">存活</span>率<span style="color: black;">常常</span>接近100%。而晚期肿瘤的治疗要<span style="color: black;">繁杂</span>的多,<span style="color: black;">存活</span>率<span style="color: black;">亦</span><span style="color: black;">显著</span>有差距。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此呢</span>,不管是<span style="color: black;">病人</span>还是<span style="color: black;">大夫</span>,都期盼着有一种神奇的<span style="color: black;">办法</span><span style="color: black;">能够</span>早点<span style="color: black;">发掘</span>癌细胞,在它们还没成气候之前将其扼杀在摇篮中。</p>

<h2 style="color: black; text-align: left; margin-bottom: 10px;">血液筛查为<span style="color: black;">初期</span>诊断带来了新<span style="color: black;">期盼</span>。</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">此刻</span>大<span style="color: black;">都数</span>的体检中心,对40岁以上的人群<span style="color: black;">增多</span>了血清肿瘤标志物的检测。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">血清肿瘤标志物是血液中能够检测的一类微量蛋白。肿瘤标志物是<span style="color: black;">因为</span>肿瘤组织<span style="color: black;">自己</span>产生,反映肿瘤存在和生长的一类生化物质。<span style="color: black;">重点</span><span style="color: black;">包含</span>胚胎抗原、糖类抗原、天然<span style="color: black;">自己</span>抗原、细胞角蛋白以及肿瘤<span style="color: black;">关联</span>的酶、激素、某些癌基因等。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-67da61d72562a2f5ef93200bb6ebbd35_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在临床上,肿瘤标记物<span style="color: black;">能够</span>分为:癌胚胎性抗原,如甲胎蛋白(AFP)、癌胚抗原(CEA);异位激素,如绒毛膜促性腺激素(HCG)、促肾上腺皮质激素、降钙素;酶和同工酶,如乳酸脱氢酶、神经元特异性烯醇化酶、前列腺酸性磷酸酶;<span style="color: black;">血液</span>蛋白,如β2、巨球蛋白;肿瘤抗原,如CA199、CA125;肿瘤基因和肿瘤基因蛋白产物,如c、myc、ras、p53、Rb;微量元素,如砷、铜、铁、锌、硒等。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤标记物可用于<span style="color: black;">帮忙</span><span style="color: black;">发掘</span>、诊断和处理某些类型的癌症。虽然肿瘤标记物<span style="color: black;">上升</span>可能提示存在癌症,<span style="color: black;">然则</span>仅有肿瘤标记物<span style="color: black;">上升</span>不足以诊断癌症。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-c5aa5694bb1e52ce087a14c9ef28ba7d_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">举个例子,肝癌是临床上一种<span style="color: black;">平常</span>的肿瘤类型,而甲胎蛋白则是对肝癌有<span style="color: black;">要紧</span>提示的一种指标。正常<span style="color: black;">状况</span>下,人<span style="color: black;">身体</span>血清中的甲胎蛋白含量不到20ug/L,但若<span style="color: black;">病人</span>的肝细胞<span style="color: black;">显现</span>癌变,肝脏细胞就会恢复产生这种蛋白的功能,就会<span style="color: black;">引起</span>癌症<span style="color: black;">病人</span>血清中的甲胎蛋白含量<span style="color: black;">显著</span><span style="color: black;">上升</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">通常</span><span style="color: black;">状况</span>下,<span style="color: black;">病人</span>在肝癌<span style="color: black;">出现</span>症状前8个月起,甲胎蛋白水平就会<span style="color: black;">显现</span><span style="color: black;">显著</span><span style="color: black;">升高</span>,<span style="color: black;">因此</span><span style="color: black;">病人</span><span style="color: black;">倘若</span>存在慢性肝病、肝硬化,应当经常复查这种指标,来<span style="color: black;">知道</span><span style="color: black;">自己</span>的肝脏<span style="color: black;">疾患</span><span style="color: black;">是不是</span>恶变。但总体<span style="color: black;">来讲</span>,肿瘤标记物的诊断并非100%,不<span style="color: black;">能够</span>单凭借甲胎蛋白<span style="color: black;">升高</span><span style="color: black;">做为</span>肝癌的诊断“金标准”。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;">血液筛癌黑科技即将诞生:一滴血认癌,灵敏度高,卵巢癌误诊率为0。</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">有<span style="color: black;">科研</span>人员<span style="color: black;">研发</span>出了一种血液学检测<span style="color: black;">办法</span>,<span style="color: black;">经过</span><span style="color: black;">评定</span>血液中存在的游离DNA和游离蛋白筛查出了8种<span style="color: black;">平常</span>癌症,<span style="color: black;">包含</span>卵巢癌、肝癌、胃癌、胰腺癌、食管癌、结直肠癌、肺癌以及乳腺癌。更神奇的是,它还能告诉<span style="color: black;">咱们</span>原发肿瘤的位置!</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic1.zhimg.com/80/v2-a41d0cc3b86cf63265ae08b11fabcb88_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">CancerSEEK<span style="color: black;">怎样</span>找到肿瘤呢?<span style="color: black;">首要</span>,<span style="color: black;">经过</span>检测突变的基因<span style="color: black;">能够</span><span style="color: black;">发掘</span><span style="color: black;">有些</span>因基因突变所<span style="color: black;">引起</span>的癌症,但相同的基因突变可能会<span style="color: black;">引起</span>不同的肿瘤,例如<span style="color: black;">一样</span>是EGFR突变,可能<span style="color: black;">引起</span>肺癌,<span style="color: black;">亦</span>可能<span style="color: black;">引起</span>结直肠癌。<span style="color: black;">此时</span>,再利用蛋白标志物<span style="color: black;">供给</span><span style="color: black;">相关</span>肿瘤部位的信息,例如,癌胚抗原的<span style="color: black;">反常</span><span style="color: black;">上升</span>提示胃肠道肿瘤。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">拿到<span style="color: black;">病人</span>的血液样本后,<span style="color: black;">首要</span>扩增<span style="color: black;">病人</span>血液中的DNA,数量越多,癌症的<span style="color: black;">检测</span>率越高。CancerSEEK面板中还添加了<span style="color: black;">病人</span>和健康人群对照组中数量差别巨大、诊断特异性高达99%的蛋白片段。<span style="color: black;">这般</span>就<span style="color: black;">能够</span><span style="color: black;">同期</span>探测血液中的DNA和游离蛋白了,这不仅<span style="color: black;">能够</span>在癌症<span style="color: black;">初期</span><span style="color: black;">发掘</span>肿瘤细胞的存在,还能<span style="color: black;">知道</span>肿瘤细胞的器官起源。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">CancerSEEK在<span style="color: black;">非常多</span>癌症的探测中表现了不俗的成绩,尤其在卵巢癌的筛查中,预测原发灶的准确率高达100%。尽管现<span style="color: black;">周期</span>CancerSEEK尚<span style="color: black;">处在</span><span style="color: black;">科研</span>状态,但这种近乎<span style="color: black;">没</span>创<span style="color: black;">同期</span>能<span style="color: black;">同期</span>筛查多种癌症的手段<span style="color: black;">导致</span>医疗界很大的关注,等到它<span style="color: black;">作为</span>适用于临床的癌症筛查手段,<span style="color: black;">非常多</span>癌症<span style="color: black;">病人</span>将会从中获益。</p>
