New Imaging Technique Detects Prostate Cancer Recurrence with 70 Percent Accuracy: Study Finds
A new Canadian study has shown that a novel imaging technique, prostate-specific membrane antigen (PSMA) positron emission tomography (PET) scanning, is significantly more effective at detecting recurrent prostate cancer than standard imaging methods—and can lead to better survival outcomes. The findings, published in The Journal of Nuclear Medicine, come from a seven-year, multi-centre study.
Prostate cancer is the most commonly diagnosed cancer among Canadian men, and recurrence after initial treatment remains a major challenge. Traditional imaging methods, such as CT and bone scans, often fail to detect the location of returning cancer, especially when blood tests indicate recurrence but imaging cannot confirm it. To address this gap, researchers turned to PSMA PET scans, which involve injecting a radioactive molecule into a patient’s bloodstream that binds specifically to proteins found in prostate cancer cells. This makes the cancer easier to detect using PET imaging.
