Evaluating cancer-associated fibroblasts using PET imaging

Evaluation Using FAPI-PET Targeting Cancer-associated Fibroblasts

NA · Osaka University · NCT05442151

This study is testing a new type of PET imaging to see if it can better help doctors understand and treat pancreatic and gastric cancer by looking at the supportive tissue around the tumors.

What this trial studies

This study evaluates the use of a specific PET imaging agent, [18F] FAPI-74, to assess cancer-associated fibroblasts in patients diagnosed with malignant tumors, particularly pancreatic and gastric cancers. The approach involves comparing the results of this imaging technique with traditional FDG-PET/CT scans to gain a deeper understanding of the tumor pathology. By focusing on the cancer stroma, which constitutes a significant portion of tumors, the study aims to enhance diagnostic accuracy and treatment planning for affected patients.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with malignant tumors or those suspected of having such tumors who have undergone prior imaging.

Not a fit: Patients who are pregnant, pediatric patients requiring sedation, or those deemed inappropriate for the study will not benefit.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic methods for cancer, allowing for more tailored and effective treatment strategies.

How similar studies have performed: Other studies using similar PET imaging techniques have shown promise, indicating potential for success in this approach.
