OICR-funded clinical trial shows value in advanced biopsy techniques for men with low-risk prostate cancer

Many of the 23,000 men across Canada who will be diagnosed with prostate cancer this year won’t need aggressive treatment. Instead, men with low-risk or slow-growing cancers may be offered ‘active surveillance’, where their healthcare team monitors their cancer closely with regular tests, scans and biopsies. Dr. Laurence Klotz, a world leader in active surveillance, is working to improve how surgeons in Ontario and across Canada perform these important prostate biopsies.

Klotz, who is a leading urologic surgeon and researcher at Sunnybrook Health Sciences Centre, teamed up with collaborators in London, Hamilton, Kitchener and Toronto to bring the latest MRI-guided prostate biopsy techniques to patients across the province. With OICR’s support, they evaluated the use of MRI-targeted biopsies, where a surgeon uses MRI images to help guide biopsy needles, relative to traditional biopsies, and found that the use of MRI results in 50 per cent fewer failures of surveillance. The findings from their two-year study were recently published in European Urology.

“As shown in other countries like the U.K. and Australia, using MRI before biopsies can reduce the diagnosis of insignificant cancers, selectively find aggressive cancers and reduce the number of false negatives,” says Klotz. “Our study showed that using MRI allows us to better pinpoint prostate cancers as they progress.”

Learnings from this study have helped inform the design of a new trial, called PRECISE, that is evaluating whether MRI can replace biopsies and spare some men from the associated side effects. Results from PRECISE will be submitted for publication in the next few months.

“We’ve laid the groundwork for better prostate cancer diagnosis,” says Klotz. “This means we’re one step closer to ensuring each man receives the most appropriate treatment for his individual cancer.”

OICR congratulates Drs. Mark Levine, Eduardo L. Franco and Gerald Batist, new recipients of the Order of Canada

Dr. Mark Levine

Three cancer researchers were invested into the Order of Canada over the weekend, including Dr. Mark Levine, C.M., who was honoured for his contributions as an oncologist, researcher and clinician and because he has developed several new treatments for cancer patients that are now used as standard of practice in Canada.

Levine is Director of the Ontario Clinical Oncology Group (OCOG), Chair of the Department of Oncology for the Michael G. DeGroote School of Medicine at McMaster University and a medical oncologist at Juravinski Cancer Centre at Hamilton Health Sciences.

Making prostate cancer diagnosis more PRECISE

Dr. Laurence Klotz of the Sunnybrook Research Institute

Dr. Laurence Klotz of Sunnybrook Health Sciences Centre is a world leader in the field of prostate cancer research. He has been a champion of active surveillance (also known as watchful waiting) for over 20 years, an approach to prostate cancer treatment that has allowed thousands of men with low-risk prostate cancer to avoid or delay therapy by monitoring it closely instead of immediately treating it.

Now Klotz has launched a new clinical trial called PRECISE, funded with $3 million in support by the Movember Foundation, the Ontario Institute for Cancer Research and Prostate Cancer Canada, that will use MRI to help to better diagnose prostate cancer without invasive biopsy.

Clinical trial launched to test use of MRI to improve prostate cancer diagnosis and management

Research supported by the Movember Foundation, the Ontario Institute for Cancer Research and Prostate Cancer Canada

Toronto, ON – June 1, 2016 – The Movember Foundation, the Ontario Institute for Cancer Research (OICR) and Prostate Cancer Canada today announced $3 million in funding for a new Phase III clinical trial to evaluate if magnetic resonance imaging (MRI) can replace the current standard of care to diagnose prostate cancer. The primary objective of the multi-centre trial, called PRECISE, is to determine whether MRI imaging can spare some men from undergoing a biopsy and avoid the possible associated side effects.

The trial will be led by Dr. Laurence Klotz of the Sunnybrook Research Institute in Toronto, a world leader in the field of prostate cancer research and in the global adoption of active surveillance, a standard practice to monitor patients with low risk prostate cancer.
