Most patients rely on follow-up observations to monitor the disease, which does not meet clinical needs. 68Ga-grazytracer is a novel imaging agent targeting granzyme B. By detecting the concentration of granzyme B, it reflects the localization of cytotoxic T cells in the tumor region and their potential ability to kill tumor cells. This study aims to leverage the simplicity, non-invasiveness, visualization, and semi-quantitative advantages of 68Ga-grazytracer PET imaging to evaluate its effectiveness and feasibility in diagnosing pseudoprogression.",[45,46,47],"PET \u002F CT","Lung Carcinoma","Immunotherapy","2024-09-19",{"date":50,"type":51},"2024-09-23","ACTUAL",{"date":53,"type":51},"2024-06-20",{"date":55,"type":41},"2025-12-31",{"name":5,"class":6},1]
