Clinical Study of CLDN18.2 PET/CT for Noninvasive Diagnosis of Gastric and Pancreatic Cancer

Summary

In this study, we will investigate the diagnostic efficacy and safety of \[18F\]F-H3RESCA-3A12 and \[68Ga\]Ga-NOTA-3A12 in metastatic gastric and pancreatic cancers, and evaluate the sensitivity and specificity of the use of \[18F\]F-H3RESCA-3A12 and \[68Ga\]Ga-NOTA-3A12 for diagnosing metastatic gastric and pancreatic cancers . This study will provide a new method for the noninvasive target-specific diagnosis of gastric and pancreatic cancer, and provide intuitive and clear imaging basis for clinical diagnosis, differential diagnosis and treatment.
