        <p style="text-align: justify; margin: 0; color: #444;">
            <strong>大细胞神经内分泌癌</strong>（LCNEC）是一种罕见且侵袭性极高的肺部恶性肿瘤，虽然在 WHO 分类中被归类为<strong>[[非小细胞肺癌]]</strong>（NSCLC）的一个亚型，但其生物学行为和临床特征更接近<strong>[[小细胞肺癌]]</strong>（SCLC）。LCNEC 具有独特的“嵌合”特性：细胞形态巨大（像 NSCLC），但表达神经内分泌标记物（像 SCLC）。随着 <strong>[[NGS]]</strong> 技术的发展，LCNEC 目前被认为是一组异质性疾病。根据 <strong>NCCN Guidelines (v1.2026)</strong>，治疗策略正从传统的“一刀切”转向基于 <strong>[[TP53]]</strong> 和 <strong>[[RB1]]</strong> 基因状态的精准分层治疗。
