Immunotherapy (PD-1/PD-L1 inhibitors) has attracted attention for lung cancer treatment and recasted the administration of immunotherapeutics to patients who have advanced/metastatic diseases. Whether in combination or as monotherapy, these medications have become common therapies for certain patients with lung cancer. Moreover, their usage is expected to expand widely in the future. This review aims to discuss the imaging evaluation of lung cancer response to PD-1/PD-L1 therapy with focus on new radiological criteria for immunotherapy response. Abnormal radiological responses (pseudoprogression, dissociative responses, and hyperprogression) and immune-related adverse events are also described.
免疫疗法(PD-1/PD-L1 抑制剂)在肺癌治疗中引起了关注,并重新调整了免疫治疗药物在晚期/转移性疾病患者中的应用。这些药物无论是联合使用还是作为单一疗法,都已成为某些肺癌患者的常见治疗方法。此外,预计它们的使用在未来将广泛扩展。本文旨在讨论 PD-1/PD-L1 治疗肺癌反应的影像学评估,重点介绍免疫治疗反应的新影像学标准。还描述了异常的影像学反应(假性进展、分离反应和超进展)和免疫相关不良事件。
