Filter by:This is a single-arm prospective non-randomized, non-blinded trial to assess the safety of neoadjuvant stereotactic body radiation therapy (SBRT) before surgery in high risk prostate cancer patients. Radiation therapy will be delivered over 5 treatment sessions for approximately 1.5 weeks total.
This research study is being done to develop a new test to identify prostate cancer patients at highest risk of radiotherapy-related complications. This research study would allow monitoring of total tissue damage within 24 hours of radiation exposure in blood samples that could give an initial result within a few days that would help clinicians make treatment decisions. Detection of unusual tissue damage at this early time, well before symptoms occur, could allow doctors to tailor interventions that could include patient therapies that would reduce or prevent the problems that occur due to treatment of their cancer.
Background: The immune system is the cells and organs in the body that recognize and fight infection and cancer. The prostate specific antigen (PSA)/TRICOM (PROSTVAC) vaccine might teach the immune system to find and kill certain prostate cancer cells. Nivolumab is a drug that allows the immune system to fight tumors. It might help PROSTVAC work better. Objective: To test the safety and effectiveness of the combination of PROSTVAC and nivolumab. To test this for people with castration resistant prostate cancer and then for other people with localized prostate cancer who are candidates for surgical removal of the prostate. Eligibility: Men ages 18 and older with prostate cancer Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Electrocardiogram Bone scan Computed tomography (CT) scan or magnetic resonance imaging (MRI) Tumor sample. This may be from a previous procedure. All participants will get a combination of the study drugs over 8 weeks. They will have 1 visit for the initial injection then 3 booster injection / nivolumab infusion visits. Blood will be tested at these visits. Over the next 4 weeks, some participants will have: An exam of the large intestine through the rectum. CT and bone scans Standard hormonal treatment Option to continue treatment every 3 weeks if their disease does not get worse. They will have scans every 12 weeks. Other participants will have surgery to remove the prostate in week 9. Participants will have a safety visit about a month after their last treatment. This will include a physical exam, blood tests, and possibly scans. If their cancer progresses, participants will leave the study and may enroll in a long-term follow-up study. They will be contacted once a year to ask about their cancer and treatment.
Abiraterone acetate (AA) has shown a favourable impact in overall survival, administered with prednisone to decrease the adverse event related to CYP171A suppression. Our hypothesis is that the change of prednisone to dexamethasone in CRPC patients that progress biochemically to AA + prednisone can improve the number and the length of the responses, and also improve tolerance to treatment, decreasing the adverse events associated to a moderate dosage of steroids used chronically.
The investigators are imaging patients with prostate cancer using a new PET imaging agent (Ga-68-PSMA-11) in order to evaluate it's ability to detection prostate cancer in patients with high risk disease prior to prostatectomy.
The objective of this study was to compare the efficacy and safety of the combination therapy with enzalutamide + androgen deprivation therapy (ADT) and the combination therapy with flutamide + ADT in patients with castration resistant prostate cancer who had relapsed during combined androgen blockade (CAB) therapy with bicalutamide and ADT. This study also investigated the order of alternative antiandrogen therapy (AAT) by changing the 1st line medication after relapse of prostate-specific antigen (PSA).
The investigators are imaging patients with prostate cancer using a new PET imaging agent (Ga-68-PSMA-11) in order to evaluate it's ability to detection prostate cancer in patients with biochemical recurrence after prostatectomy and radiation therapy.
MRI findings after successful PAE in patients suffering from BPH suggest a complete necrosis of the prostate after this intervention. Thus, PAE might also play a role in the treatment of prostate cancer. This proof of concept study assess the impact of PAE in patients with proven prostate cancer.
The purpose of this study is to test a novel diagnostic Positron Emission Tomography (PET) imaging agent for safety and biodistribution. The agent binds Prostate Specific Membrane Antigen (PSMA) and is designed to detect prostate tumors.
Cancer-related fatigue (CRF) can be experienced by individuals with Prostate Cancer (PC), which can have profound effects on their well-being. Although physical activity has been shown to improve CRF, the recommended levels are generally not met. Step count and distance traveled information can help individuals to increase their physical activity. Wearable technology (WEAR) provides the user with feedback of their physical activity which can motivate behaviour change. Similarly, education workshops (EDU) on the effects of sedentary behaviour and physical activity may also reduce sedentary behaviour. The objectives of this study are to evaluate the effects of WEAR and EDU on sedentary behaviour and CRF, and to explore the feasibility of WEAR in this population. Participants in this study will be randomly assigned into WEAR, EDU, WEAR+EDU, or control over a three-month intervention. Assessments at baseline, post-intervention and a 3-month follow up will evaluate CRF, quality of life and level of sedentary behaviour, and use of WEAR devices. The results from this study will provide evidence-based knowledge on the impact of WEAR and EDU on sedentary behaviour and CRF, and an understanding on the use of technology within the PC population. These results can shape the development of programming for CRF and the use of scale-able technology-based interventions/approaches in this population.
