Filter by:RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is studying blood samples from patients with metastatic prostate cancer previously treated with bicalutamide and goserelin.
disulfiram is a DNA methyltransferase inhibitor that may provide benefit for patients with prostate cancer by restoring tumor suppressor genes.
RATIONALE: Lycopene and green tea may stop or delay the development of recurrent prostate cancer in patients has been treated for prostate cancer. It is not yet known whether lycopene or green tea may be more effective in preventing prostate cancer. PURPOSE: This randomized phase II trial is studying lycopene to see how well it works compared with green tea in preventing prostate cancer in patients previously enrolled in the ProtecT trial
RATIONALE: L-arginine supplements may improve the quality of life and erectile function in men who are prostate cancer survivors. PURPOSE: This randomized phase II trial is studying how well L-arginine supplementation works with or without enzyme inhibitors in treating erectile function and quality of life of prostate cancer survivors previously treated with radiation therapy.
This research study is being done to collect regular and routine follow-up information related to the outcome of treatment for prostate cancer. This study is also being done to relate treatment outcome to measurement of substances in the blood such as prostate-specific antigen (PSA) and other markers. Also environmental and genetic factors that might be responsible for prostate cancer are being investigated.
The primary objective of this study is to evaluate the safety and feasibility of Magnetic Resonance Image (MRI) guided focal prostate cancer laser thermal ablation in males, ages 40-80 with biopsy confirmed early clinical stage prostate cancer (T1c or T2a) with an identifiable lesion on mutliparametric MRI, with a Prostate Specific Antigen (PSA) of < 15ng/ml, who have not yet undergone pelvic radiation or hormonal deprivation therapy.
Background: - Currently, there is no curative therapy for metastatic castrate-resistant prostate cancer (CRPC), a leading cause of death in men. However, researchers are exploring new treatments that involve drugs that prevent angiogenesis (the process by which new blood vessels are formed) and can slow or prevent tumor growth. - TRC105 is an experimental drug that blocks angiogenesis, and has been studied for possible use in treating different kinds of cancer. However, it has not been validated to treat prostate cancer in general or CRPC in particular. Objectives: - To determine the effects of TRC105 as a treatment for CRPC - To determine the safety and effectiveness of TRC105 in treating CRPC Eligibility: - Men at least 18 years of age who have been diagnosed with castrate-resistant prostate cancer for which existing treatments have not been effective. Design: - Eligible individuals will have a series of blood and other tests to determine their suitability for participating in the study. - Participants will receive intravenous infusions of TRC105 in a 28-day treatment cycle. Participants will receive i.v. (intravenous) infusions of TRC105 every two weeks on days 1 and 15 of each 28-day cycle (cohorts 1, 2, 3, 5, and 6) and every week on days 1, 8, 15, and 22 of each 28 day cycle (cohort 4). - Participants will receive different doses of TRC105 depending on when they enter the study, up to a maximum tolerated dose or optimum treatment dose. - Frequent blood and urine tests will be performed during treatment, as well as other tests of cancer progression as directed by the study doctors. Participants will receive medicines to help prevent possible adverse side effects of TRC105, such as allergic reaction to the drug. - Participants will continue treatment with TRC105 until they or the study team decides that the medication is not beneficial. No additional testing will be required unless participants discontinue the treatment because of side effects (which the study doctors will follow until the side effects are resolved).
Erectile dysfunction is a frequent adverse event after radical prostatectomy for prostate cancer. It is the consequence of penile vascular damage, mainly arterial insufficiency and venous leakage associated with fibrosis of the corpus cavernous. Apoptosis of penile cells, including mesenchymal cells, smooth muscle cells and endothelial is believed to play an important role in the pathophysiology of post prostatectomy erectile dysfunction. Bone marrow mononucleated cells (BMMNC) contain different cell types that may replace the damaged penile cells after radical prostatectomy. These are mainly: mesenchymal stem cells, endothelial progenitor cells and hematopoietic stem cell. Intracavernous injection of BMMNC may therefore find application in the treatment of post prostatectomy erectile dysfunction. The aims of this phase I-II study is to test the safety of autologous intracavernous BMMNC injection and to evaluate benefit for the patient concerning recovery of natural erection. Patients with penile vascular abnormality (echo-doppler) and localized prostate cancer (considered as cured by radical prostatectomy) will be included in this study. Four different doses of BMMNC will be tested.
The goal of this clinical research study is to find out how treatment with abiraterone acetate in combination with prednisone and a Luteinizing Hormone-Releasing Hormone (LHRH) analogue changes the tumor in comparison to treatment with an LHRH analogue alone. Objectives: Primary Objective: To assess the difference in pathologic stage < pT2 between Group A and Group B. Secondary Objective: - To assess and compare the changes in levels of androgens (pre, during, and post treatment) in the serum, primary tumor microenvironment and bone marrow between Group A and Group B. - To assess changes in biomarkers related to androgen signaling and other cancer-related pathways between Group A and Group B. - To assess the difference in rate of positive surgical margins between Group A and Group B. - To assess the safety profile of abiraterone acetate and low dose prednisone in a preoperative setting.
Assess whether the combination of ABT-888 with temozolomide (TMZ) has activity in subjects with metastatic castration resistant prostate cancer (CRPC) as reflected by the prostate-specific antigen (PSA) response.
