Imaging technique to assess cancer tissue before surgery

PET Biodistribution Study of 68Ga-PSMA-11 and 68Ga-FAPI-46 in Patients With Non-Prostate Cancers: An Exploratory Biodistribution Study With Histopathology Validation

Early Phase 1 Interventional Jonsson Comprehensive Cancer Center · NCT04147494

This study is testing a new imaging technique to see how well it can show cancer tissue in patients with different types of cancer before they have surgery.

What this trial studies

This phase I trial investigates a new imaging technique called FAPi PET/CT to evaluate the accumulation of a PET tracer in normal and cancer tissues in patients with various non-prostate cancers. The study aims to correlate the imaging results with the actual tumor tissue that will be surgically removed. Participants may also have the option to undergo an additional imaging scan using a different tracer, PSMA PET/CT, and those who have not had a recent FDG PET/CT will receive that as well. The goal is to enhance the understanding of tumor biology and improve surgical outcomes.

Who should consider this trial

Good fit: Ideal candidates include patients with breast, colon, esophageal, gastric, head and neck, lung, ovarian, pancreatic, renal, or uterine cancers who are scheduled for surgical resection.

Not a fit: Patients who are pregnant or nursing, or those who have received new cancer therapy recently may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate imaging techniques that improve surgical planning and outcomes for cancer patients.

How similar studies have performed: While this approach is innovative, similar imaging techniques have shown promise in other studies, suggesting potential for success.
