<strong>[[晚期前列腺癌]]</strong>（<strong>[[Advanced Prostate Cancer]]</strong>）是指前列腺癌病灶突破包膜并发生局部侵犯或远处转移（如[[骨转移]]、[[淋巴结转移]]）的恶性状态。其核心分子病理机制高度依赖于<strong>[[AR]]</strong>（[[雄激素受体]]）信号通路的持续激活。临床进程通常经历从<strong>[[转移性激素敏感性前列腺癌]]</strong>（[[mHSPC]]）向<strong>[[转移性去势抵抗性前列腺癌]]</strong>（[[mCRPC]]）的演变。在[[mCRPC]]阶段，即便循环[[睾酮]]达到去势水平，肿瘤仍能通过[[AR基因扩增]]、[[AR突变]]或[[剪接变异体]]（如[[AR-V7]]）维持生长。随着[[PSMA]]核素治疗及[[PARP抑制剂]]的应用，晚期前列腺癌已进入基于基因分型的精准治疗时代。<br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
前列腺癌的演进主要受[[AR]]信号轴驱动，即便在去势治疗下，肿瘤仍能通过多种路径维持通路活性：<br />
</p><br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>AR过表达与扩增：</strong>肿瘤细胞通过增加[[AR]]蛋白数量或[[AR]]基因拷贝数，极大地提高了对极低浓度[[双氢睾酮]]（[[DHT]]）的敏感性。</li><br />
<li style="margin-bottom: 12px;"><strong>配体结合域（LBD）突变：</strong>特定的点突变（如[[T878A]]、[[W742C]]）可改变[[AR]]的构象，使[[孕酮]]、[[雌激素]]甚至部分[[抗雄药物]]（如[[比卡鲁胺]]）反而激活[[AR]]。</li><br />
<li style="margin-bottom: 12px;"><strong>[[AR剪接变异体]]：</strong>例如[[AR-V7]]，该变异体缺失了配体结合域，导致[[AR]]处于配体非依赖性的持续激活状态，预示着对[[阿比特龙]]、[[恩扎卢胺]]等药物的原发性耐药。</li><br />
<li style="margin-bottom: 12px;"><strong>[[DNA损伤修复]]（DDR）缺陷：</strong>约20%-30%的[[mCRPC]]患者携带[[BRCA1]]、[[BRCA2]]或[[ATM]]基因突变，这赋予了肿瘤极高的基因组不稳定性，但也使其对[[PARP抑制剂]]产生敏感。</li><br />
</ul><br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
晚期前列腺癌的现代管理正从单一激素阻断转向垂直整合的综合治疗：<br />
</p><br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>新型内分泌治疗（NHA）：</strong>如<strong>[[阿比特龙]]</strong>（抑制雄激素合成酶[[CYP17A1]]）及<strong>[[恩扎卢胺]]</strong>、<strong>[[阿帕他胺]]</strong>、<strong>[[达罗他胺]]</strong>（直接拮抗[[AR]]）。</li><br />
<li style="margin-bottom: 12px;"><strong>[[PSMA]]靶向疗法：</strong>利用前列腺特异性膜抗原（[[PSMA]]）的高表达，开发[[Lutetium-177 PSMA-617]]核素疗法，精准消灭转移性微小病灶。</li><br />
<li style="margin-bottom: 12px;"><strong>[[合成致死]]策略：</strong>针对携带[[DDR]]缺陷（如[[BRCA1/2]]）的患者，使用[[奥拉帕利]]或[[瑞卡帕利]]。</li><br />
<li style="margin-bottom: 12px;"><strong>细胞毒化疗：</strong>针对高肿瘤负荷或内分泌耐药患者，使用[[多西他赛]]或[[卡巴他赛]]。</li><br />
<li style="margin-bottom: 12px;"><strong>[[免疫微环境]]调节：</strong>虽然[[PD-1]]抑制剂在整体人群中有效率受限，但在具有[[MSI-H]]或[[dMMR]]特征的亚群中仍具显著意义。</li><br />
