Summary

Currently, there are limited methods available in clinical practice to distinguish pseudoprogression after immunotherapy. 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.
