研究目的:

这项Ⅱ期试验的目的是研究低剂量放疗(LDRT)对免疫治疗后非小细胞肺癌(NSCLC)寡转移、寡进展和寡生残留病灶肿瘤免疫微环境(TME)的影响。本研究将招募至少 20 名参与者。所有参与者都将在和田地区人民医院接受治疗。  

Objectives of Study:

The purpose of this phase Ⅱ trial was to investigate the effect of low-dose radiotherapy (LDRT) on the tumor immune microenvironment (TME) in oligometastasis, oligoprogression, and oligopersistence of non-small cell lung cancer (NSCLC) after immunotherapy. At least 20 participants will be enrolled in this study. All will take part at Hetian District People’s Hospital.

药物成份或治疗方案详述:

针对寡转移灶的LDRT已被证明可通过重编程TME增强抗肿瘤免疫力,从而提高免疫治疗的疗效。本研究的目的是在LDRT(5Gy/5f)前和LDRT后24小时内,收集免疫治疗后NSCLC寡转移、寡进展和寡生存的病理组织,以应用多重荧光免疫组化(mIHC)评估肿瘤免疫微环境。这项研究将能够探讨免疫治疗后LDRT对NSCLC寡转移病灶TME的影响,并评估LDRT的有效性和安全性。 

Description for medicine or protocol of treatment in detail:

LDRT targeting oligometastases has been shown to enhance anti-tumour immunity by reprogramming the TME, thereby improving the efficacy of immunotherapy. The aim of this study was to collect pathological tissues from oligometastasis, oligoprogression, and oligopersistence of NSCLC after immunotherapy before LDRT (5Gy/5f) and up to 24h after LDRT in order to apply multiplexed fluorescence immunohistochemistry (mIHC) for evaluation of the tumor immune microenvironment. This study will be able to investigate the effect of LDRT on TME in oligometastatic lesions of NSCLC after immunotherapy and assess the efficacy and safety of LDRT.
