胃肠道间质瘤的免疫治疗

胃肠间质瘤(GISTs)是最常见胃肠道间叶组织肿瘤,传统放化疗无效,手术完整切除是可能治愈该病的唯一方法。虽然GISTs靶向治疗效果显著,但KIT或PDGFRA基因多位点突变和/或二次突变导致靶向治疗耐药及复发率逐年升高,因此寻找新方法成为治疗GISTs研究热点。GISTs内部存在大量肿瘤浸润免疫细胞和复杂免疫微环境,多种免疫细胞参与GISTs发生、发展,且在靶向治疗中发挥重要作用,GISTs免疫治疗基础及临床试验结果均证实GISTs免疫治疗的可行性及有效性。本文系统总结了GISTs免疫治疗现状及最新研究进展。

Immunotherapy of Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumors(GISTs)are the most common mesenchymal tumors of the gastrointestinal tract and respond poorly to conventional radiochemotherapy.Complete excision is the only possible way to cure GISTs.Although targeted therapy is effective for GISTs,multiple and/or secondary mutations of KIT or PDGFRA gene have lead to increased drug resistance and disease relapse.A variety of tumor infiltrating immune cells and complex immune microenvironments have been found in GISTs.Many immune cells participate in the occurrence and development of GISTs and play key roles in targeted therapy.The feasibility and effectiveness of immunotherapy for GISTs have been well demonstrated in preclinical and clinical studies.
