PSMA PET SCAN

Australian First in Prostate Cancer staging following the introduction of PSMA PET/CT.

Wesley Medical Imaging (WMI) was the first private facility to offer a PET service in Australia. As the leading provider of PET imaging WMI also pioneered Ga-68 PSMA PET scanning for prostate cancer.

Australia’s Prostate Centre of excellence at the Wesley Hospital has adopted a heavy research focus both within the radiology and urology departments. The willingness of the clinicians to trial new imaging modalities and the uptake of PSMA PET/CT (contradicting international guidelines) has essentially placed them years ahead throughout the world – “trail blazers” as described in Aunt Minnie’s article on the recent publication of the study- “Five-year trends of bone scan and prostate-specific membrane antigen positron emission tomography utilization in prostate cancer: A retrospective review in a private centre”

The study published online April 11 in the Journal of Medical Imaging and Radiation Oncology, describes the trends of use between PSMA PET/CT and Nuclear Medicine Bone Scans (NMBS) by urologists at the Wesley Hospital for prostate cancer following the introduction of PSMA PET/CT.

Wesley Medical Imaging (WMI) was the first institution in Australia to offer both imaging modalities.

Despite the ongoing evaluation of the performance of PSMA PET/CT, compared to NMBS and CT imaging, there is little information regarding the use of these modalities in the real world by clinicians. The study evaluated trends in prostate cancer staging/re-staging imaging modalities between the time period January 2013 to April 2018, reviewing the imaging logs and radiology reports.

Six months after WMI began performing PSMA PET/CT scans, the average number of monthly NMBS plummeted by almost 50% in favour of PSMA PET/CT. Five years later the rate of NMBS used for staging prostate cancer had dropped by 95% – showing in almost all cases urologists were choosing PSMA PET/CT for their patients instead.

” PSMA PET/CT filled a really obvious need for our Urologists. Urologists surveilling their patients would see PSA levels slowly rising, repeat imaging to investigate and receive a negative result.  Whereas once they started doing PSMA PET/CT on their patients, given the increased sensitivity, they could actually see the early tumour recurrence.” Assoc. Prof David Wong said.
