Filter by:The purpose of this study is to evaluate the effects of the study drug, BKM120. The study drug, BKM120, is an inhibitor of a protein called phosphatidyl inositol-3-kinase (PI3K). This protein is found in normal cells and in cancer cells, but often in many cancer cells this protein is overactive. Inhibiting the protein may slow the growth of prostate cancer but this has not been tested yet in men with prostate cancer.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Androgen deprivation therapy may stop the adrenal glands from making androgens. Radiation therapy uses high-energy x-rays to kill tumor cells. PURPOSE: This randomized phase III trial studies androgen-deprivation therapy and radiation therapy in treating patients with prostate cancer.
The purpose of this trial is to give a shorter course (5 ½-6 weeks) of proton radiation that has as little side effects on normal bladder and rectal tissues as the usual longer course (8 weeks) of proton radiation, without decreasing the chance of killing prostate cancer cells.
This is a multi-centre, prospective, randomized phase III trial to determine if multi-parametric Magnetic Resonance Imaging (MRI) can improve selection of patients eligible for active surveillance through better detection of clinically significant cancer.
One of the biggest problems facing prostate cancer patients and their treating physicians is who needs to be treated and when. Common clinical and pathological parameters are useful (PSA, Gleason score, etc.) but do not clearly predict who will benefit from treatment and who will fail. Genetic markers for tumor aggressivity would be of greater value. The finding that the TMPRSS2-ERG gene fusion is associated with an increase risk of cancer progression is important. TMPRSS2 is controlled by androgen (testosterone) and ERG is part of a family of proteins which have a role in controlling cell growth, cell specialization and producing tumors. As a consequence of this gene fusion, production of the ERG protein increases in the presence of testosterone and could be key to the development of prostate cancer, resistance to treatment and poor outcome. The PTEN gene is known to have a role as a tumor suppressor. Its deletion is a contributing factor in the development of prostate cancers and poor outcome. The coexistence of the two markers could be associated with a higher risk of recurrence. To date there have been no studies regarding the presence of either of these two markers or their coexistence in high risk prostate cancer patients who, despite radiation therapy and androgen suppression, develop biochemical failure (their PSA levels rise once again). Patients participating in the PCS IV study (high risk prostate cancer treated with radiation therapy plus either 18 or 36 months of hormonal suppression) who have had biochemical failure or 3 years of follow-up post hormonal therapy will be approached. Tumor blocks from consenting patients will be collected and analyzed for the presence of the TMPRSS2-ERG gene fusion and the PTEN deletion at the Pathology Department of the Jewish General Hospital. Statistical analysis will be carried out to see whether either or both markers are present, whether they are associated with certain clinical and pathological high risk factors, and whether they can be used to predict which patients will fail treatment.
The purpose of this study is see if quality of life is improved in patients receiving oral hormone therapy compared to standard of care. The study will also compare survival rates between patients receiving oral hormone therapy and those receiving standard of care.
Prostate cancer is the most common cancer in American men. Surgical removal of the entire prostate (prostatectomy) is one option among the various ways to treat prostate cancer. The use of robot assistance for prostatectomy has become common place, but its effectiveness has not been compared to standard open prostatectomy in trials carried out at more than one medical institution in which participants are identified and followed forward in time. Robot assisted and standard open prostatectomy health related quality of life (HRQOL) outcomes have not been compared in a prospective, multi-centered study. Prostatectomy can have side effects that can change with time. This research study seeks to determine how common and how long-lasting such side effects are; to find out what features of individual men's cancers and what features of the treatments affect those side effects. This study also seeks to identify factors that affect the quality of prostate cancer care by looking at how satisfied men are with their prostate cancer care. Through these findings, this study aims to allow treatment side effects to be anticipated more accurately for individual patients, and to provide a means for determining the quality of prostate care.
The purpose of this study is to show that abiraterone acetate plus prednisone added to the current standard of care, gonadotropin-releasing hormone (GnRH) decreases prostate specific antigen (PSA) and prolongs the time until it is evident that the cancer has grown. Additionally, safety information about abiraterone acetate in combination with prednisone will be collected. This will include looking at what side effects occur, how often they occur, and for how long they last.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Antiandrogen drugs, such as abiraterone acetate, may lessen the amount of androgens made by the body. It may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying the side effects and how well abiraterone acetate works in treating patients with prostate cancer who have undergone initial hormone therapy.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known which radiation therapy regimen is more effective in treating patients with relapsed prostate cancer. PURPOSE: This randomized phase III trial is studying the side effects of radiation therapy and comparing two radiation therapy regimens in treating patients with relapsed prostate cancer after surgery.
