血液肿瘤标志物加强就必定是肺癌吗?并非如此,怎么样才可使之降低
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">近期</span>有个亲戚参加单位体检,报告提示癌胚抗原略高于正常,为9.5ug/L,非常紧张的向我咨询是不是得癌症了?<span style="color: black;">怎样</span>把癌胚抗原降下来呢?这个问题真不是一句话能说的清的,<span style="color: black;">思虑</span>到这个亲戚平时抽烟较多,且癌胚抗原高的并不多,我<span style="color: black;">意见</span>他<span style="color: black;">一月</span>之后再复查,<span style="color: black;">倘若</span>继续<span style="color: black;">提升</span>,则<span style="color: black;">必须</span>做胃肠镜及CT等<span style="color: black;">检测</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">癌胚抗原是一项肿瘤标志物,它是广谱肿瘤标志物,在胃肠道恶性肿瘤、乳腺癌、肺癌、胰腺癌、食管癌、卵巢癌等肿瘤中都有可能<span style="color: black;">上升</span>,脏器特异性低。<span style="color: black;">亦</span><span style="color: black;">便是</span>说癌胚抗原的<span style="color: black;">升高</span>并<span style="color: black;">不可</span>特定的诊断哪种癌症,只能<span style="color: black;">做为</span>提示某些癌症的可能性存在。<span style="color: black;">因此</span>,癌胚抗原<span style="color: black;">不可</span><span style="color: black;">做为</span>诊断癌症的依据。<span style="color: black;">针对</span>健康体检人群当癌胚抗原<span style="color: black;">上升</span>超过5-10倍以上时,要高度<span style="color: black;">可疑</span>体内恶性肿瘤存在,<span style="color: black;">即时</span>做其他<span style="color: black;">检测</span>,<span style="color: black;">包含</span>其他肿瘤标志物、胸腹部CT、胃镜、肠镜等等,<span style="color: black;">知道</span>癌胚抗原<span style="color: black;">上升</span>的<span style="color: black;">原由</span>。<span style="color: black;">针对</span><span style="color: black;">已然</span>确诊癌症的病人,在评判治疗效果的时候,<span style="color: black;">能够</span>将这个指标<span style="color: black;">做为</span>参考指标。<span style="color: black;">例如</span>肺癌靶向治疗<span style="color: black;">或</span>化疗后癌胚抗原<span style="color: black;">显著</span>下降,提示有<span style="color: black;">必定</span>的治疗效果。在癌症治疗结束后的随访中,<span style="color: black;">亦</span><span style="color: black;">能够</span><span style="color: black;">做为</span>判断复发转移的参考指标。肺癌术后病人随访中,<span style="color: black;">倘若</span>癌胚抗原呈缓慢<span style="color: black;">提升</span>,要<span style="color: black;">可疑</span>肿瘤有复发及微转移可能。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">癌胚抗原的正常值为<5μg/L,癌胚抗原数值越低越好,但几乎不可能为0,这是<span style="color: black;">由于</span>癌胚抗原是在胚胎时胃肠道、肝、胰腺合成的一种蛋白质,在成年人胃肠道中<span style="color: black;">亦</span>有少量合成,<span style="color: black;">因此呢</span>,在正常成年人血清中<span style="color: black;">亦</span>有微量的癌胚抗原。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic1.zhimg.com/80/v2-7059d896f12d41601e5a96dd97749b04_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;">癌胚抗原高就<span style="color: black;">必定</span>会是癌症吗?并不是,除了肿瘤外,吸烟、妊娠期会<span style="color: black;">显现</span>癌胚抗原<span style="color: black;">上升</span>,心血管<span style="color: black;">疾患</span>、糖尿病、非特异性结肠炎、直肠息肉、胰腺炎、胆囊炎、肝硬化、肝炎、酒精性肝病、肺部<span style="color: black;">疾患</span>等良性<span style="color: black;">疾患</span>,血清癌胚抗原<span style="color: black;">亦</span>可能会<span style="color: black;">上升</span>,<span style="color: black;">此时</span>候<span style="color: black;">上升</span><span style="color: black;">通常</span>为轻度,<span style="color: black;">因此</span>癌胚抗原不是恶性肿瘤的特异性标志,在诊断上<span style="color: black;">仅有</span>辅助价值。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-e7e1849a39b4e2c7612a8ebeb41d12dd_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;">癌症病人癌胚抗原<span style="color: black;">必定</span>会高吗?并不是,结直肠癌在<span style="color: black;">初期</span>未转移时,癌胚抗原阳性率为45%~80%<span style="color: black;">上下</span>,已转移的<span style="color: black;">病人</span>癌胚抗原的浓度和阳性检出率均<span style="color: black;">上升</span>。胰腺和胆道肿瘤的阳性率<span style="color: black;">达到</span>60%~70%,胃癌、肺癌阳性率50%<span style="color: black;">上下</span>。可见,并不是所有癌症病人癌胚抗原<span style="color: black;">必定</span>会<span style="color: black;">上升</span>,即便是胃癌、肠癌、肺癌病人<span style="color: black;">亦</span>有近一半的病人癌胚抗原是正常范围的,有部分晚期病人从<span style="color: black;">发掘</span>到最后癌胚抗原都是正常的。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">非常多</span>人说癌胚抗原这个指标名字<span style="color: black;">欠好</span>,不<span style="color: black;">认识</span>的人一听就觉得是与癌<span style="color: black;">相关</span>的指标。它确实与癌<span style="color: black;">相关</span>,但<span style="color: black;">上升</span>又不<span style="color: black;">必定</span>都是癌症<span style="color: black;">导致</span>的。癌胚抗原<span style="color: black;">怎样</span>降低,那得看是哪方面的<span style="color: black;">原由</span>,<span style="color: black;">倘若</span>是抽烟<span style="color: black;">或</span>良性<span style="color: black;">疾患</span><span style="color: black;">导致</span>的轻度<span style="color: black;">上升</span>,数值会稳定不变,高一点<span style="color: black;">亦</span><span style="color: black;">不消</span>担心,<span style="color: black;">定时</span>复查就行了。<span style="color: black;">倘若</span>确诊是癌症<span style="color: black;">导致</span>的癌胚抗原<span style="color: black;">上升</span>,那就得积极的抗肿瘤治疗,才有可能让其下降。</p>
一看到楼主的气势,我就觉得楼主同在社区里灌水。 楼主继续加油啊!外链论坛加油!
