Filter by:This trial studies the side effects and how well high-dose brachytherapy works in treating patients with prostate cancer that has not spread to other parts of the body. Brachytherapy is a type of radiation therapy in which radioactive material sealed in needles, seeds, wires, or catheters is placed directly into or near a tumor and may be a better treatment in patients with prostate cancer.
The primary goal of this phase II study is to compare the change of EPIC HRQOL scores (1-year minus baseline) between SBRT and IMRT.
This phase I trial studies the side effects and best dose of metformin hydrochloride when given together with enzalutamide in treating patients with prostate cancer that has not responded to previous treatment with hormones. Hormone therapy using enzalutamide may fight prostate cancer by lowering the amount of androgens the body makes and blocking the use of androgens by the tumor cells. Metformin hydrochloride, used for diabetes, may also help kill tumor cells. Giving enzalutamide together with metformin hydrochloride may kill more tumor cells.
Prostate cancer, the most frequently diagnosed cancer among occidental men, is associated with a major individual and societal burden. Although still controversial, the literature suggests that a high consumption of omega-3 fatty acids (ω3) has protective effects against prostate cancer. One of the proposed mechanisms of action of ω3 lies in their anti-inflammatory properties. In addition, there are some observational evidences suggesting an association of ω3 intake with a lower rate of depression in cancer patients. However, no clinical study has tested the efficacy of ω3 supplementation on psychological and quality of life outcomes in that population. Several evidences point to a possible involvement of inflammation in psychological issues. Reducing the systemic inflammatory state may have beneficial impact on the quality of life of these patients. Preliminary work from this team of investigators, in a cohort of patients managed with active surveillance for their low-grade prostate cancer, show a strong inverse association between the risk of prostate cancer progression (to high-grade) and the level of prostatic eicosapentanoic acid (EPA- a type of ω3). HYPOTHESIS: EPA-rich monoglycerides fish oil (MAG-EPA) has global positive effects on prostate cancer cell proliferation, inflammation and on the patient's psychosocial functioning and quality of life. The investigators propose a double blind, randomized controlled clinical trial. 130 consecutive patients suffering from high-risk prostate cancer who choose to be treated by radical prostatectomy will be eligible to this study. The presence of high-grade cancer will be mandatory. The intervention, a daily supplementation with 3g supplement of fish oil monoglycerides rich in EPA, vs. placebo capsules containing high oleic sunflower oil, will start six weeks before the prostatectomy and will continue for one year after surgery. The potential confounding variables will be measured before the start of the intervention: age, anthropometric parameters, stage and clinical and pathological tumor grade (Gleason score), pre-operative level of prostate specific antigen and diet. This project proposes a simple intervention by dietary supplementation that could eventually help to reduce the incidence and/or progression of prostate cancer, and the consequences of its treatment, and thus could contribute to diminish the heavy individual and societal burden of prostate cancer. The clinical data generated by this trial will serve as solid basis for a large-scale phase III clinical trial.
The purpose of this study is to assess enzalutamide plus leuprolide in patients with high-risk nonmetastatic prostate cancer progressing after radical prostatectomy or radiotherapy or both. The randomized / blinded portion of the study is now completed following primary endpoint analyses. The study remains ongoing in open label format.
This phase II trial studies how well pembrolizumab works in treating patients with prostate cancer that has spread to other places in the body and keeps growing even when the amount of testosterone in the body is reduced to very low levels despite previous treatment with enzalutamide. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells.
The purpose of this study is to better understand prostate cancer changes after radiation treatment, through magnetic resonance imaging (MRI). MRI is an imaging test that allows doctors to see prostate gland without any operation procedures. It can help identifying the tumors in the prostate. For patients with newly diagnosed prostate cancer, MRI may help doctors manage treatment better and sooner.
Evidence to justify the use of the pelvic field is lacking for men with high risk localized prostate cancer. An additional randomized study is needed in men with a potential risk of nodal involvement to test the hypothesis that the use of the pelvic field contributed to the benefit observed in those studies. This trial aims to compare the outcomes with whole pelvis RT and Prostate alone RT in patients with High risk, non metastatic Prostate cancer with a Lymph nodal >20% with Primary 5 year Biochemical failure free survival and Secondary Disease free survival, overall survival, Acute toxicity, Late toxicity and QOL Patients will be randomized to one of two arms Arm 1 Whole pelvis radiotherapy and Arm 2 Prostate only radiotherapy. The Dose prescription will be 66 Gy in 25 fractions will be prescribed for the prostate PTV in Arm 2 an additional 50 Gy in 25 fractions for nodal PTV in patients in Arm 1. An overlap volume at rectal-prostate interface will receive 64 Gy/25#. All patients will receive hormone therapy starting at least 8 weeks prior to the beginning of radiotherapy. They will continue the hormone therapy and later for a total duration of 2-3 years.
This clinical trial studies stereotactic body radiation therapy in treating patients with high-risk prostate cancer that has not spread to nearby lymph nodes or to other parts of the body. Stereotactic body radiation therapy is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may kill more tumor cells and cause less damage to normal tissue. Studying quality of life in patients undergoing stereotactic body radiation therapy may help identify the long-term effects of treatment on patients with prostate cancer.
To assess the early histological outcomes of tissue ablation, adverse events and genitourinary side-effect profile of focal radiofrequency ablation using a coiled bipolar device to treat localized prostate cancer in men with clinically significant prostate cancer.
