Advanced gastroesophageal cancer in which surgical resection is no longer appropriate is an aggressive malignancy with poor prognosis. This review provides an overview of the key trials that have led to the current standard of care, both highlighting progress with systemic cytotoxic and biological therapies, but also calling attention to pitfalls to assist practitioners in optimizing currently available treatments for their patients. This review surveys recent and ongoing trials and biomarker studies regarding the use of anti-HER2 agents, with increased recognition of molecular intratumoral heterogeneity confounding such targeted therapy strategies. We conclude with an overview of recent major trials incorporating immune checkpoint inhibitors among patients with metastatic and locally advanced gastroesophageal cancer and providing a framework for the discriminate application of these new therapies.
手术切除不再适用的晚期胃食管癌是一种侵袭性恶性肿瘤,预后较差。本综述概述了促成当前治疗标准的关键试验,既强调了全身细胞毒性和生物疗法的进展,也提醒注意一些陷阱,以帮助从业者为患者优化现有治疗方案。本综述调查了关于使用抗HER2药物的近期和正在进行的试验以及生物标志物研究,同时越来越认识到肿瘤内分子异质性会混淆此类靶向治疗策略。我们最后概述了近期在转移性和局部晚期胃食管癌患者中纳入免疫检查点抑制剂的主要试验,并为这些新疗法的区别应用提供了一个框架。
