Comparative Study of Radiotherapy Treatments to Treat High Risk Prostate Cancer Patients
Prostate CancerIn North America, the number of new cases of prostate cancer increases every year. Many efforts have been made to develop more efficient and safer curative treatments for high risk prostate cancer patients. This phase III clinical trial is designed to compare the safety of a standard pelvic external beam radiation therapy (EBRT) combined with a high dose rate brachytherapy (HDRB) boost (direct insertion of radiation source over a period of minutes via flexible needles temporarily inserted in the prostate) to a shorter course of hypofractionated dose escalation radiotherapy (larger radiation dose per daily treatment) in patients with high risk prostate cancer. The investigators plan to recruit 296 patients across Quebec who will be randomized in either treatment plan.
Carbon Ions Boost Followed by Pelvic Photon Radiotherapy for High Risk Prostate Cancer
Adenocarcinoma of ProstateThe aim of this research project is to test the feasibility and safety of a new treatment schedule for high risk prostate cancer that allows the administration of high doses to the prostate tumor with a mixed beam approach of carbon ions boost followed by pelvic IMRT.
A Study to Test Radium-223 With Docetaxel in Patients With Prostate Cancer
Prostate CancerThe purpose of this study is to compare any good and bad effects of using radium-223 along with docetaxel chemotherapy treatment versus using docetaxel alone. Earlier studies helped show that the combination is safe, but the combination has not been proven to work better than either drug alone. The goal of this study is to find out if combining docetaxel and radium-223 is better than giving either drug by itself.

Prostate Oncologic Therapy While Ensuring Neurovascular Conservation (POTEN-C)
Prostate Cancer AdenocarcinomaReduction of dose to or 'sparing' of neurovascular structures during stereotactic ablative body radiotherapy (SAbR) for localized prostate cancer will improve retention of sexual potency, while retaining excellent oncologic control and other secondary health-related quality of life (HRQOL) endpoints. Primary Objectives: • To compare the decline in patient health-related quality of life (HRQOL) instrument-defined erectile dysfunction following stereotactic ablative body radiotherapy (SAbR) with or without neurovascular sparing Secondary Objectives: Assess acute (within 3 months of treatment) and chronic (>3 months after treatment) SAbR related GU and GI toxicities, as well as serial impact on HRQOL metrics over time Assess biochemical progression free survival, local recurrence, distant recurrence, and survival Evaluate simplified 'practical' secondary HRQOL sexual potency endpoints that can be compared to prior literature. Exploratory Objectives: Evaluate feasibility of MRI BOLD/TOLD to be integrated as hypoxia monitoring sequences to standard already planned diagnostic and/or treatment planning MRI on the study in five patient pilot. Evaluate quality of spacer placement and its effect on dose to neurovascular structures Evaluate rate local recurrence in the area of sparing adjacent to the neurovascular elements by biopsy in those with biochemical progression.
Apalutamide With or Without Stereotactic Body Radiation Therapy in Treating Participants With Castration-Resistant...
Castration Levels of TestosteroneCastration-Resistant Prostate Carcinoma2 moreThis phase II trial studies the how well apalutamide with or without stereotactic body radiation therapy work in treating participants with castration-resistant prostate cancer. Testosterone can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. It is not yet known whether giving apalutamide with or without stereotactic body radiation therapy works better in treating participants with castration-resistant cancer.
Phase II High Dose Brachytherapy and Low Dose Rate Brachytherapy as Monotherapy in Localized Prostate...
Prostate CarcinomaThe purpose of this study is to evaluate the dose of High Dose Rate (HDR) brachytherapy chosen for this study as well as a commonly used alternate form of brachytherapy called low dose rate (or seed) brachytherapy. Investigators would like to understand how these treatments control the prostate cancer and look at their short and long term treatment related side effects. The dose of radiation for HDR brachytherapy for this study has been changed since the study started. Other studies using the dose of radiation for HDR brachytherapy that was originally chosen for this study (Arm 2) found that this dose of radiation may be linked to a greater chance of the cancer coming back in the prostate. Therefore since March 2020, for new participants entering the study, a new HDR brachytherapy arm with a higher amount of radiation given over two doses will be tested in this study
HDR Focal: Feasibility Study
Prostate CancerBrachytherapy as a monotherapy treatment is highly effective for localized prostate cancer, traditionally being delivered to the whole prostate gland. Lately, low dose rate (LDR) brachytherapy has been increasingly replaced by high dose rate (HDR) brachytherapy treatment schemes. While brachytherapy's oncologic outcomes are excellent, it is not without incidence adverse effects including urinary, rectal, and sexual toxicities that affect the patient's quality of life. This study will incorporate HDR monotherapy treatment option for early stages and favourable risk prostate cancer. Additionally, we aim to evaluate the role of focal HDR brachytherapy for well-defined disease based on multiparametric MRI (mpMRI). This approach may offer an option of reducing the treatment toxicities while maintaining oncologic outcomes when compared with whole-gland therapy. Advantages in quality of life could be exhibited in the form of reduced urinary discomfort and incontinence, rectal symptoms, and improved erectile and prostatic gland function. This study would be particularly relevant in the current era of earlier localized prostate cancer detection, where newer imaging modalities (e.g. mpMRI) become a routine component of patient care.
