Two studies: Speeding development of novel tracer for prostate cancer

RESTON, Va.--The collaborative work being performed by professionals across medical disciplines in the promising area of molecular imaging--from research scientists to nuclear medicine physicians, urologists, radiochemists and even veterinarians--provides encouraging news in fighting prostate cancer. This type of progressive--or translational--research can be seen in two papers published in the January issue of the Journal of Nuclear Medicine.

Researchers at Emory University in Atlanta, Ga., and at Nihon Medi-Physics' research center in Chiba, Japan, collaborated closely in examining the potential of using the radiotracer FACBC to better stage or determine prostate cancer spread, said David M. Schuster, an assistant professor and director of the division of nuclear medicine and molecular imaging in Emory's radiology department. "Our two studies show the progression of molecular imaging in what is called translational research, the process of taking research and finding useful applications for it with patients," added co-author of "Initial Experience With the Radiotracer Anti 1-Amino-3-[18F]Fluorocyclobutane-1-Carboxylic Acid (Anti-[18F]FACBC) With PET/CT in Prostate Carcinoma." Together with "A Preliminary Study of Anti 1-Amino-3-[18F] Fluorocyclobutyl-1-Carboxylic Acid for the Detection of Prostate Cancer," the two papers illustrate the development of a promising radioisotope tracer (a radioactive substance) from in vitro stage (in a test tube) to in vivo (within a live subject) in animals to in vivo in individuals with prostate cancer, explained Schuster. The Emory pilot study with FACBC, performed with only 15 patients, shows that the amino acid analog may hold the potential to provide information to better stage or determine prostate cancer spread, said Schuster. He stressed that FACBC is not available for use with patients, and additional research needs to be done with larger groups of patients.
