The purpose of the study is to show that 3 targeted biopsies on the suspicious image detected by IRM, guided by a fusion of MRI and ultrasound- images with the Koelis ® system, will get no lower rate of cancer detection than those obtained by 12 systematic transrectal ultrasound-guided biopsies of the prostate.
Prostate Cancer (PC) affects 1 in 7 men. Nearly half of those diagnosed with PC will receive androgen deprivation therapy (ADT) as part of their treatment. ADT is good at managing PC but has many side effects. Researchers have shown that exercise, specifically one-on-one supervised exercise improves many of the side effects of ADT. However, exercise programs for men on ADT are not widely available. More questions need to be answered in order for exercise programs to become part of PC treatment. First, can programs that require fewer resources, such as group-exercise or home-based exercise, also improve ADT side-effects? Second, do exercise-related benefits continue beyond the structured exercise program? And what makes people continue exercising? Third, which exercise program is most cost-effective? In this study, the investigators will compare: (a) group supervised in-centre; (b) home-based supported; and (c) 1:1 supervised in-centre exercise programs to see which program is most effective for men with PC on ADT. The investigators will also look at what motivates people to continue to exercise both during a structured program and after the program is complete and will examine which exercise program is most cost-effective. The investigators will ask men with PC on ADT that are being treated at either Princess Margaret Cancer Centre in Toronto or the Tom Baker Cancer Centre in Calgary to participate in the study. When a patient agrees to participate, he will be randomly placed in 1 of the 3 exercise programs. All programs will include the same type of exercises (aerobic, resistance and flexibility) and all participants will exercise 4-5 days per week for 30 minutes per day (as tolerated) for the length of the program (6 months). The investigators will look at how men with PC on ADT respond to the exercise program by measuring quality of life (QOL), fatigue and different physical measures before, during, and after the exercise program. Although the investigators know that supervised one-on-one exercise is most effective at improving ADT side-effects, it is unknown if other forms of exercise are just as beneficial and more financially responsible. This study will allow the investigators to begin to answer these questions so that structured exercise programs become a regular part of PC treatment.
This is a phase II randomized controlled trial (RCT) of 2 strategies to improve bone health in men receiving androgen deprivation therapy (ADT).
This study aims to evaluate patients with metastatic castrate-resistant prostate cancer (mCRPC) undergoing treatment with sipuleucel-T for evidence of treatment-associated immune activation in lymph nodes and peripheral blood.
The EndoWrist One Vessel Sealer is a bipolar electrosurgical instrument for use with the da Vinci Si robotic surgical system. It is intended for bipolar coagulation and mechanical transection of vessels up to 7 mm in diameter and tissue bundles that fit within the jaws of the instrument. Their use in this study will be to perform tissue transection during PLND such that the intended use is within the FDA-approved domain for this instrument. Investigators intend to identify whether its use for PLND reduces lymphoceles given that the device is known to seal vessels up to 7 mm, which is much larger than lymphatic vessels encountered during PLND. Because the instrument is new and has been FDA approved for less than one year, there is no published literature regarding its use to date. Our hypothesis is that using the Vessel Sealer on a single side of the pelvis will reduce the incidence of screening detected lymphoceles on that side. Investigators propose a total sample size of 120 patients.
This study will ultimately aim to evaluate the side effects of treatment by asking 20 subjects to receive post-operative radiotherapy for prostate cancer with the treatment plan adapted after the first week of treatment to account for changes in the target shape. These patients will be asked to complete toxicity scores and a quality of life questionnaire at the start and completion of treatment, and at 3 months 1, 2 and 5 years from the start of radiotherapy. These results will be used to determine the feasibility of the proposed approach, and obtain early estimates of improvements in uncertainty margin requirements for this population of patients.
This prospectively designed retrospective clinical utility study will evaluate urologists' treatment recommendations before and after reviewing Decipher results for selected patient cases.
This clinical utility study is based on a review of real but de-identified and randomized patient cases and aims to evaluate radiation oncologist's treatment recommendations before and after reviewing the results provided by the Decipher test. The primary intent is to help guide development and design of future clinical utility studies for Decipher.
Men with early prostate cancer face a number of options which lie at the extremes of care. On one hand, active surveillance involves monitoring the disease and on the other, immediate treatment involves surgery or radiotherapy. The difference between these two strategies in terms of reducing the chance of a man dying from his disease is small. Not only is the benefit small, surgery or radiotherapy carry significant side-effects. These occur because of damage to surrounding tissue resulting in incontinence of urine (1 in 5), erectile dysfunction (1 in 2) and back-passage bleeding, diarrhoea or discomfort (1 in 10). The investigators have been working on new forms of treatment that use heat, light or cold to destroy tissue and minimise treatment-related harms. The investigators have not yet found one that delivers the ideal treatment. The ideal treatment is one that can be done under local anaesthetic, can effectively destroy areas of cancer, limit damage to surrounding tissues, is repeatable, and adaptable to future discoveries such as molecular targeting of cancer cells. The investigators think magnetic thermoablation may be able to deliver on these ideal attributes. Magnetic thermoablation involves injecting magnetic iron nanoparticles directly into the cancer. When a magnetic field is applied close to them, these nanoparticles heat up to very high temperatures that kill cells. Magnetic thermoablation does not use x-rays or surgical incisions. The investigators have done a lot of the preclinical work already to develop this type of treatment. The investigators now need to develop a system that can be used to treat prostate cancer. However, before the investigators can do this, they need to test whether the magnetic nanoparticles actually stay where they are injected. The consequences of them moving to areas that they should not can be serious. First, the nanoparticles could move away from the cancer which means the cancer will not be heated effectively. Second, the nanoparticles could move to sensitive structures around the prostate (back-passage, bladder, sphincter muscle controlling urine flow, nerves controlling erections). If this happens, damage of those sensitive structures could occur leading to side-effects. The investigators propose a study to try and find out what happens to those nanoparticles. The study will involve approaching men who are having their prostates removed by radical surgery. If these patients agree to participate, the investigators will inject their prostate with varying amounts of nanoparticles. The investigators will NOT heat them up. The investigators will use special scans and, once they have had their surgery, to look at the pathology specimens to see where the nanoparticles have gone. The actual nanoparticles are not harmful but the process of injection can carry a small amount of harm. If the nanoparticles stay where they are injected, the investigators will then be able to run another study in which we treat men who have prostate cancer with magnetic thermoablation.
