Coordinating Center: Southeast Phase 2 Consortium (SEP2C), Moffitt Cancer Center.
Research participation involves up to three experimental imaging examination visits in radiology: a baseline before the patient starts a cancer treatment, a follow-up a few days later, and a later follow up to see how the treatment may affect normal or abnormal processing of Tryptophan.
The research imaging results will be linked with other evidence of the patient's disease, but will not effect their care.
