Summary
This trial is testing a new imaging procedure that may help doctors better assess a patient's response to cancer treatment and plan future treatment.
Who is the study for?
Adults over 18 with certain cancers (brain, breast, neuroendocrine, colorectal) and visible tumors at least 1cm in diameter. Participants must be able to undergo a PET/CT scan for 70 minutes and not be pregnant or breastfeeding. They should have an ECOG performance status of ≤2 and meet specific criteria based on their cancer type.
What is being tested?
The trial is testing the effectiveness of a new imaging procedure using F-Tryptophan PET/CT to distinguish between tumor tissue and non-tumor tissue in various cancers. The goal is to improve treatment planning by better identifying how tumors take up Tryptophan.
What are the potential side effects?
As this trial focuses on an imaging technique rather than a drug intervention, side effects are minimal but may include discomfort from lying still during the scan or reactions related to contrast agents if used.
