广泛期小细胞肺癌放射治疗进展

广泛期小细胞肺癌(extensive-stage small cell lung cancer,ES-SCLC)约占小细胞肺癌((small cell lung cancer,SCLC)的2/3,治疗以化疗为主,辅以放疗等综合治疗。虽然SCLC对放化疗反应敏感、初治缓解率高,但几乎所有ES-SCLC都会发生复发及进展,迫切需要新的治疗策略以提高疗效。近年来,放疗在ES-SCLC中进展主要包括脑预防照射(prophylactic cranial irradiation,PCI)和胸部放疗(thoracic radiotherapy,TRT)。此外,免疫检查点抑制剂展现了良好的抗肿瘤活性,有望成为该领域治疗的重要突破口。本文将对ES-SCLC在放疗和免疫治疗以及其他治疗的临床研究进展方面进行综述。

Advances in radiotherapy for extensive-stage cell lung cancer

Extensive-stage small cell lung cancer (ES-SCLC) accounts for approximately two-thirds of all SCLCs. Chemotherapy is still the main treatment, supplemented with radiotherapy and other comprehensive treatments. Although sensitive to chemotherapy and radiotherapy, almost all ES-SCLCs are vulnerable to treatment resistance and have high recurrence rates. Therefore, novel therapies are needed to improve treatment efficacy. The recent advances in radiotherapy for ES- SCLC include prophylactic cranial irradiation (PCI) and thoracic radiotherapy (TRT). Moreover, immunotherapy has shown good antitumor activity, and immune-checkpoint inhibitors may become an important breakthrough in SCLC treatment. This article briefly reviewed the clinical research on radiotherapy and immunotherapy for advanced-stage SCLC.
