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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The patients are enrolled from Department of Respiratory and Critical Care Medicine, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine in China.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
