研究目的:

主要目的: 以免疫治疗疗效评估标准(RECIST 1.1和 iRECIST)和生存期数据为参考,评价68Ga-grazytracer 对晚期转移性胃肠道肿瘤免疫疗效的早期评估效能。 次要目的: 1)比较基线和中期68Ga-grazytracer PET/CT显像健康组织、器官及肿瘤性病变的放射性摄取差异。 2)探索68Ga-grazytracer PET/CT预测 ICI 诱导的肿瘤直径减小(客观缓解率)的最佳SUVmax界值。 3)比较68Ga-grazytracer PET/CT与RECIST 1.1标准早期预测免疫响应的诊断效能。 探讨68Ga-grazytracer摄取程度(SUVmax)与血清生物学指标、免疫响应及生存期之间的相关性。  

Objectives of Study:

Main purpose: Using the evaluation criteria of immunotherapy efficacy (RECIST 1.1 and iRECIST) and survival data as reference, evaluate the early evaluation efficacy of 68Ga grazytracer in the treatment of advanced metastatic gastrointestinal tumors. Secondary purpose: 1) Compare the differences in radiation uptake between baseline and mid-term 68Ga grazytracer PET/CT imaging of healthy tissues, organs, and tumor lesions. 2) Explore the optimal SUVmax threshold for predicting ICI induced tumor diameter reduction (objective response rate) using 68Ga grazytracer PET/CT. 3) Compare the diagnostic efficacy of 68Ga grazytracer PET/CT with RECIST 1.1 standard for early prediction of immune response. Explore the correlation between the uptake level of 68Ga grazytracer (SUVmax) and serum biological indicators, immune response, and survival.
