Summary

This study is a diagnostic study. Patients and healthy volunteers with clinically suspected or confirmed colorectal cancer, gastric cancer, pancreatic cancer and other malignant tumors with high expression of GPA33 will be recruited for PET/MR or PET/CT imaging targeting a GPA33-specific probe (in the case of \[68Ga\]Ga-NOTA-GPA33 nanobody) , to observe the reaction of volunteers and patients after injection of drugs, to evaluate the pharmacokinetics in vivo and the efficacy of diagnosis and staging, and to perform PET imaging in patients with contraindications. General information on the subjects' vital signs, clinical data, blood routine, liver and kidney functions and other biochemical indicators and other imaging data were collected, and histopathology of biopsy or surgical specimens was used as the final diagnostic criterion.

DRUG

68Ga-NOTA-GPA33 nanobody

To perform integrated PET/MR or PET/CT visualization of patients with clinically suspected or confirmed colorectal cancer, gastric cancer, pancreatic cancer and other malignant tumors with high GPA33 expression and healthy volunteers, using specific positron imaging agents target GPA33(in the case of \[68Ga\]Ga-NOTA-GPA33 nanobody) , to achieve the following purposes: Patients with malignant tumors: for diagnosis and staging of diseases, comparing with the gold standard pathological diagnosis, evaluating diagnostic efficacy, clarifying the presence or absence of lesions, and determining the location and nature of lesions; comparing with \[18F\]FDG PET for accurate staging, evaluating the tumor load, and helping to determine the therapeutic plan. Healthy volunteers: Pharmacokinetic analysis will be performed to clarify the distribution and metabolism of the drug in the body and its safety.
