<strong>DCP</strong>（Des-gamma-carboxy Prothrombin，异常凝血酶原），又称为 <strong>PIVKA-II</strong>，是凝血酶原（因子 II）的一种异常形式。<br />
<br>正常情况下，肝脏合成凝血酶原需要<strong>维生素 K</strong> 参与谷氨酸的羧化。在<strong>[[肝细胞癌]]</strong>（HCC）细胞中，由于羧化酶系统缺陷或维生素 K 利用障碍，导致产生了这种无凝血功能但具有促有丝分裂活性的异常蛋白。DCP 是目前公认的 HCC <strong>高特异性</strong>标志物，常用于<strong>[[AFP]]</strong>（甲胎蛋白）阴性肝癌的补充诊断，且与<strong>门静脉癌栓</strong>（PVTT）的形成密切相关。<br />

<li style="margin-bottom: 12px;"><strong>排除炎症干扰：</strong> AFP 在慢性肝炎、肝硬化等良性肝病活动期常会有中低度升高，造成假阳性。而 DCP 在良性肝病中极少升高（除非伴有严重的维生素 K 缺乏），因此更能准确区分肝癌与肝硬化。</li><br />
<li style="margin-bottom: 12px;"><strong>预后评估：</strong> DCP 具有促进肿瘤细胞增殖和血管生成的生物活性。DCP 高水平往往提示肿瘤体积大、存在微血管侵犯或<strong>门静脉癌栓（PVTT）</strong>，预示着预后较差。</li><br />
<li style="margin-bottom: 0;"><strong>治疗监测：</strong> 肝癌切除或消融后，DCP 半衰期较短（约 3 天），下降速度快，比 AFP 更能早期反映治疗效果。</li><br />

DCP 的检测原理基于维生素 K 循环的阻断，因此任何影响维生素 K 的因素都会直接导致结果失真。<br />

<strong>1. PIVKA-II：</strong> DCP 的另一个常用名称（Protein Induced by Vitamin K Absence or Antagonist-II）。在临床检验报告中，这两个名称常互换使用，指代同一物质。<br />
</p><br />
<br />
<p style="margin: 12px 0; border-bottom: 1px solid #e2e8f0; padding-bottom: 10px;"><br />
<strong>2. GALAD Score：</strong> 一个基于血清学的肝癌预测模型。结合了 <strong>G</strong>ender（性别）、<strong>A</strong>ge（年龄）、AFP-<strong>L</strong>3、<strong>A</strong>FP 和 <strong>D</strong>CP 五项指标，能显著提高早期 HCC 的检出率。<br />
</p><br />
<br />
<p style="margin: 12px 0;"><br />
<strong>3. AFP-L3 (甲胎蛋白异质体)：</strong> 肝癌细胞特有的 AFP 糖链结构变异体。DCP、AFP 和 AFP-L3 构成了著名的“肝癌血清学三联检”。<br />
