Tryptophan Metabolism in Human Brain Tumors
In Brief
An observational study for Brain Tumors. Completed, enrolled 105 participants across 1 site.
Detailed Summary
The main purpose of this study is to determine the potential clinical utility of PET imaging using the radiotracer \[C-11\]alpha-methyl-L-tryptophan in the diagnosis, differentiation and monitoring of various brain tumors, both before and after initial treatment. We will also study mechanisms and clinical significance of abnormal brain tumor tryptophan metabolism using resected tumor tissues.
