Assessing 68Ga-DOTATATE PETCT Imaging for Diagnosing Soft Tissue Sarcomas and Planning Targeted Therapy

What this Trial Is About

Researchers are evaluating the use of 68Ga-DOTATATE digital PETCT imaging in diagnosing soft tissue sarcomas. This study aims to assess the feasibility and potential clinical benefits of this imaging method, which may improve image quality compared to existing PET techniques. It also explores tumor uptake kinetics and the possibility of using imaging results to plan future peptide receptor radionuclide therapy for patients with specific tumor types. Participants receive an intravenous injection of gallium Ga 68-HA-DOTA-TATE and undergo digital PETCT scanning for 60 minutes within two weeks after starting standard chemotherapy. About 24 hours later, they are given a fludeoxyglucose F-18 injection, followed by another 60-minute digital PETCT scan. The study uses advanced PET detector technology to evaluate tumor characteristics and simulate imaging with lower doses or faster acquisition times. During the study, participants undergo imaging assessments to measure regions with increased tracer uptake. Researchers monitor safety by tracking adverse events up to seven days after imaging. The study involves standard chemotherapy alongside the imaging procedures. The total participation duration varies but includes the imaging sessions around chemotherapy and safety follow-up shortly after. This research is sponsored by Ohio State University Comprehensive Cancer Center.
