PET Imaging Detects Fast-Growing Prostate Cancer

“A molecular imaging biomarker is able to detect fast-growing primary prostate cancer and distinguish it from benign prostate lesions, addressing an unmet clinical need. The new research, published in the July 2015 issue of The Journal of Nuclear Medicine, is significant for patients with suspected prostate cancer that has not been confirmed by standard biopsy.

” ‘We were able to demonstrate in our research that PSMA PET imaging was more specific than MR imaging for detection of clinically significant high-grade prostate cancer lesions, and importantly was able to distinguish benign prostate lesions from primary prostate cancer, currently a difficult diagnostic imaging task,’ stated Steven P. Rowe, MD, PhD, resident at Johns Hopkins Medical Institutions in Baltimore, Md. ‘Additionally, this work demonstrated a direct correlation between PSMA PET radiotracer activity in prostate cancer and prostate adenocarcinoma aggressiveness (Gleason score).’ “
