研究目的:

本课题拟开展以颗粒酶B为靶点的新型PET探针68Ga-grazytracer的研究,探讨68Ga-grazytracer PET/CT在恶性肿瘤患者中预测不同免疫疗法疗效、预后及指导治疗决策中的价值。具体如下:(1)探讨68Ga-grazytracer PET/CT对恶性肿瘤患者不同免疫疗法近期疗效的预测能力;(2)探讨68Ga-grazytracer PET/CT对恶性肿瘤患者不同免疫疗法远期预后的预测能力;(3)探讨由68Ga-grazytracer PET/CT评估的颗粒酶B摄取能否作为分层因素,以指导免疫治疗方案(单独免疫治疗vs.免疫联合化疗)的选择;(4)探讨联合颗粒酶B摄取与PD-L1表达在指导恶性肿瘤患者治疗决策中的价值。  

Objectives of Study:

This project aims to investigate a novel PET probe, 68Ga-grazytracer, targeting granzyme B, and explore the value of 68Ga-grazytracer PET/CT in predicting the efficacy of different immunotherapies, assessing prognosis, and guiding treatment decisions in patients with malignant tumors. The specific objectives are as follows: (1) To investigate the ability of 68Ga-grazytracer PET/CT to predict the short-term efficacy of different immunotherapies in patients with malignant tumors. (2) To investigate the ability of 68Ga-grazytracer PET/CT to predict the long-term prognosis of different immunotherapies in patients with malignant tumors. (3) To investigate whether granzyme B uptake assessed by 68Ga-grazytracer PET/CT can serve as a stratification factor to guide the selection of immunotherapy regimens (immunotherapy alone vs. immunotherapy combined with chemotherapy). (4) To investigate the value of combining granzyme B uptake with PD-L1 expression levels in guiding treatment decisions for patients with malignant tumors.
