68Ga-FAPI-PSMA PET Imaging for the Diagnosis of Solid Tumors
Evaluation of Dual-Targeted 68Ga-FAPI-PSMA PET/CT for the Diagnosis and Staging of Solid Tumors
This study aims to evaluate a novel dual-targeted PET imaging tracer, 68Ga-FAPI-PSMA, for the detection and evaluation of solid tumors. Fibroblast activation protein (FAP) and prostate-specific membrane antigen (PSMA) are two important molecular targets that are highly expressed in tumor cells or the tumor microenvironment. Combining these two targets into a single imaging probe may improve the sensitivity and accuracy of tumor detection.
In this single-center, open-label, self-controlled study, approximately 20 patients with suspected or confirmed solid tumors will undergo PET/CT imaging using 68Ga-FAPI-PSMA. The imaging results will be compared with standard PET tracers such as 68Ga-PSMA-617 or 68Ga-FAPI-04. The study will assess tracer uptake in tumor lesions and compare diagnostic performance between imaging methods. The results may help determine whether 68Ga-FAPI-PSMA PET/CT can improve tumor detection, staging, and clinical evaluation in patients with solid tumors.

Sperimentale: 68Ga-FAPI-PSMA PET/CT Imaging
Participants with suspected or confirmed solid tumors will undergo PET/CT imaging using the investigational tracer 68Ga-FAPI-PSMA.
Imaging findings will be compared with PET/CT performed using standard tracers such as 68Ga-PSMA-617 or 68Ga-FAPI-04 to evaluate the diagnostic performance of the dual-targeted tracer.
|
Participants will receive an intravenous injection of the investigational PET tracer 68Ga-FAPI-PSMA (0.1-0.15 mCi/kg).
Whole-body PET/CT imaging will be performed approximately 1 hour after injection.
Delayed imaging at 2-4 hours may be performed when necessary.
Imaging results will be used to evaluate tracer uptake in tumor lesions and to assess the diagnostic performance of the dual-targeted tracer.
Participants will receive an intravenous injection of the PET tracer 68Ga-PSMA-617 (0.1-0.15 mCi/kg) followed by PET/CT imaging approximately 1 hour after administration.
This imaging serves as a comparator to evaluate the diagnostic performance of the investigational tracer 68Ga-FAPI-PSMA.
Participants may undergo PET/CT imaging using the PET tracer 68Ga-FAPI-04 (0.1-0.15 mCi/kg) with imaging performed approximately 1 hour after injection.
This imaging will serve as a comparator for assessing the diagnostic performance of 68Ga-FAPI-PSMA PET/CT.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Standardized Uptake Value (SUV) of Tumor Lesions
Lasso di tempo: 1-4 hours after injection
|
The standardized uptake value (SUV) of target or suspected tumor lesions measured on 68Ga-FAPI-PSMA PET/CT imaging.
SUV values will be used to evaluate tracer uptake and diagnostic performance in solid tumors.
|
1-4 hours after injection

Tumor-to-Background Ratio (TBR) of Target Tumor Lesions on 68Ga-FAPI-PSMA PET/CT
Lasso di tempo: 1-4 hours after 68Ga-FAPI-PSMA injection
|
The tumor-to-background ratio (TBR) will be calculated as the SUVmax of the target tumor lesion divided by the SUVmean of the corresponding background normal tissue.
TBR will be used to quantitatively assess lesion contrast on 68Ga-FAPI-PSMA PET/CT.

1-4 hours after 68Ga-FAPI-PSMA injection

Mean Standardized Uptake Value (SUVmean) of Normal Organs on 68Ga-FAPI-PSMA PET/CT
Lasso di tempo: 1 to 4 hours after 68Ga-FAPI-PSMA injection
|
The mean standardized uptake value (SUVmean) of normal organs and tissues, including but not limited to the liver, spleen, kidneys, lungs, bone marrow, muscle, and blood pool, will be measured on 68Ga-FAPI-PSMA PET/CT images to characterize tracer biodistribution.

Number of Metastatic Lesions Detected by 68Ga-FAPI-PSMA PET/CT
Lasso di tempo: From the date of 68Ga-FAPI-PSMA PET/CT imaging to completion of reference-standard assessment, up to 2 months
|
The number of metastatic lesions detected by 68Ga-FAPI-PSMA PET/CT will be recorded for each participant.
Lesion detection will be compared with standard PET tracers, including 68Ga-PSMA-617 or 68Ga-FAPI-04, when available, and/or with conventional imaging or pathological findings according to the study protocol.
