            <strong>大细胞肺癌</strong>（Large Cell Lung Cancer, <strong>[[LCLC]]</strong>）是<strong>[[非小细胞肺癌]]</strong>（NSCLC）中一种未分化的亚型，属于典型的<strong>“排他性诊断”</strong>（Diagnosis of Exclusion）。它缺乏小细胞癌、腺癌或鳞癌的细胞结构和免疫组化特征。LCLC 恶性程度极高，生长迅速，早期转移倾向强，预后通常劣于其他 NSCLC 亚型。临床上最需要警惕的是其特殊亚型——<strong>[[大细胞神经内分泌癌]]</strong>（LCNEC），后者的生物学行为和治疗策略更接近<strong>[[小细胞肺癌]]</strong>。根据 <strong>NCCN Guidelines (v1.2026)</strong>，经典大细胞癌通常参照非鳞 NSCLC 标准方案治疗（免疫+化疗），而 LCNEC 则需根据基因分型制定个性化方案。
