<strong>促癌炎症</strong>（Tumor-Promoting Inflammation）是<strong>[[癌症特征]]</strong>的核心赋能属性之一。与旨在清除病原体的急性炎症不同，促癌炎症表现为一种慢性的、非消退性的免疫微环境。它通过分泌生长因子、诱导基因组不稳定性及重塑<strong>[[肿瘤微环境]]</strong>，为恶性细胞提供生存支持。在临床视阈下，促癌炎症不仅驱动肿瘤的发生与转移，更是导致<strong>[[免疫逃逸]]</strong>及耐药性的关键因素。<br />

<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>诱导遗传不稳定性：</strong> 炎症细胞释放的活性氧（<strong>ROS</strong>）和活性氮（<strong>RNS</strong>）可直接导致肿瘤细胞 DNA 损伤，加速基因突变的累积。</li><br />
<li style="margin-bottom: 12px;"><strong>调控生长与存活信号：</strong> 通过激活 <strong>NF-κB</strong> 通路，炎症因子可上调抗凋亡基因，使肿瘤细胞在极端的应激条件下依然存活。</li><br />
<li style="margin-bottom: 12px;"><strong>驱动上皮-间质转化（EMT）：</strong> 炎症微环境中的 <strong>TGF-β</strong> 信号是启动 <strong>EMT</strong> 的强效诱导剂，显著提升肿瘤的侵袭与迁移能力。</li><br />
