科学家在一项新的肿瘤微环境中研究肺癌的表皮生长因子EGFR时发现，抗PD-1药物在EGFR突变时通常是效果不佳的。然而，EGFR抑制剂厄洛替尼若与PD-1单抗药物联用的效果要胜过其中任何一种单独治疗方案，将会在肺腺癌的免疫治疗中起到重要作用。

The clinical efficacy of anti–PD-1 (programmed cell death–1) monoclonal antibody (mAb) against cancers with oncogenic driver gene mutations, which often harbor a low tumor mutation burden, is variable, suggesting different contributions of each driver mutation to immune responses. Here, we investigated the immunological phenotypes in the tumor microenvironment (TME) of epidermal growth factor receptor (EGFR)–mutated lung adenocarcinomas, for which anti–PD-1 mAb is largely ineffective. Whereas EGFR-mutated lung adenocarcinomas had a noninflamed TME, CD4+ effector regulatory T cells, which are generally present in the inflamed TME, showed high infiltration. The EGFR signal activated cJun/cJun N-terminal kinase and reduced interferon regulatory factor–1; the former increased CCL22, which recruits CD4+ regulatory T cells, and the latter decreased CXCL10 and CCL5, which induce CD8+ T cell infiltration. The EGFR inhibitor erlotinib decreased CD4+ effector regulatory T cells infiltration in the TME and in combination with anti–PD-1 mAb showed better antitumor effects than either treatment alone. Our results suggest that EGFR inhibitors when used in conjunction with anti–PD-1 mAb could increase the efficacy of immunotherapy in lung adenocarcinomas.

查了一下，以前就有K药联合特罗凯的临床，获益PFS

免疫疗法联合特罗凯有效，前天看过类似帖子
