<strong>[[耐药谱图分析]] (Resistance Profiling Analysis)</strong> 是精准肿瘤学中用于应对肿瘤 <strong>[[演化与异质性]]</strong> 的核心技术。它通过对治疗失败或疾病进展后的肿瘤组织或血液（<strong>[[液体活检]]</strong>）进行多组学检测，系统性地识别导致药物失效的分子机制。耐药谱图不仅揭示了原有的 <strong>[[驱动基因]]</strong> 发生了何种二次突变，还探测了旁路信号通路的激活或表型转化，为临床医生制定下一阶段的“接力治疗”或 <strong>[[联合用药]]</strong> 方案提供生物学证据。<br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
通过对耐药谱图的深度挖掘，科学家将复杂的耐药原因归纳为三个主要方向：<br />
</p><br />
<br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>靶点内变异 (On-target Resistance)：</strong> 药物作用的靶标蛋白发生了物理构象改变，导致药物无法结合。典型案例包括肺癌 EGFR-TKI 治疗中出现的 <strong>[[T790M]]</strong> 或 <strong>[[C797S]]</strong> 突变。</li><br />
<li style="margin-bottom: 12px;"><strong>旁路信号激活 (Bypass Activation)：</strong> 肿瘤细胞“绕路行走”，激活了另一条促进生长的通路。例如在抗 EGFR 治疗时，细胞通过 <strong>[[MET 扩增]]</strong> 或 <strong>[[HER2 扩增]]</strong> 重新获得增殖信号。</li><br />
<li style="margin-bottom: 12px;"><strong>谱系转化 (Lineage Plasticity)：</strong> 肿瘤细胞彻底改变了“身份”。例如部分腺癌在治疗压力下转化为 <strong>[[小细胞癌]]</strong> 或发生 <strong>[[上皮-间质转化 (EMT)]]</strong>，原有的靶向药物随之完全失效。</li><br />
</ul><br />
<br />
