【肿瘤检测】肺癌检测单上,这些个肿瘤指标都说明了些啥?


    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在这个谈癌色变的时代,部分人群已将肿瘤标志物检测<span style="color: black;">加入</span>体检项目,但肿瘤标志物<span style="color: black;">上升</span>就<span style="color: black;">寓意</span>着得了癌症吗?要<span style="color: black;">处理</span>这个问题,先来认识一下什么是肿瘤标志物。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤标志物又<span style="color: black;">叫作</span>Tumor Marker,<span style="color: black;">指的是</span>特征性存在于恶性肿瘤细胞,或由恶性肿瘤细胞<span style="color: black;">反常</span>产生的物质,或是宿主对肿瘤的刺激反应而产生的物质。<span style="color: black;">重点</span>用于肿瘤的早期<span style="color: black;">发掘</span>和筛查外,<span style="color: black;">帮助</span>诊断与分期,疗效监测等等。</p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">非小细胞肺癌的<span style="color: black;">关联</span>标志物<span style="color: black;">重点</span>有:CEA、Cyfra21-1、 CA125、 CA153、TPA及SCC-Ag。</p>
