Evaluating a new method to measure tumor sugar consumption using PET imaging

Evaluation of the Fractional Uptake Rate (FUR) in 18F-FDG PET/CT to Assess Tumour Metabolic Activity

Observational Academisch Ziekenhuis Maastricht · NCT05654675

This study is testing a new way to measure how much sugar tumors use by comparing a new method with a standard scan in people with cancer.

What this trial studies

This study aims to assess a novel approach for quantifying glucose consumption in tumors using PET/CT imaging. Participants will undergo a standard FDG PET/CT scan along with a dynamic PET/CT scan to evaluate the effectiveness of the fractional uptake rate (FUR) compared to the traditional standardized uptake value (SUV). Blood samples will be collected at three time points during the examination to support the analysis. The goal is to determine if the FUR provides a more accurate assessment of tumor metabolism than the SUV, which has known limitations.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18 or older who are scheduled to receive an 18F FDG PET/CT scan as part of their standard care.

Not a fit: Patients with diabetes, recent physical exercise, or those who have undergone prior cancer treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this method could lead to more accurate assessments of tumor metabolism, improving treatment decisions for patients with lung cancer and lymphoma.

How similar studies have performed: While the approach of using FUR is innovative, similar pharmacokinetic modeling methods have shown promise in other studies, suggesting potential for success.
