Filter by:RATIONALE: Studying samples of blood and tissue from patients with prostate cancer after receiving implant radiation therapy and luteinizing hormone-releasing hormone agonist may help doctors identify biomarkers related to cancer and help doctors predict how patients will respond to treatment. PURPOSE: This laboratory study is looking at PSA levels and biopsy samples after undergoing implant radiation therapy and luteinizing hormone-releasing hormone agonist therapy in patients with stage I or stage II prostate cancer.
RATIONALE: Studying samples of blood in the laboratory from patients who are at high risk of developing prostate cancer may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples from patients at high risk of developing prostate cancer and from healthy male participants.
RATIONALE: Measuring levels of transforming growth factor-beta (TGF-beta) in the blood of patients with epithelial cancers (head and neck, lung, breast, colorectal, and prostate) may help doctors predict how patients will respond to treatment with radiation therapy. PURPOSE: This research study is measuring levels of TGF-beta in patients with epithelial cancers who are undergoing radiation therapy.
RATIONALE: Studying samples of tumor tissue and 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 looking at tissue and blood samples from patients with recurrent prostate cancer who received lapatinib on clinical trial ECOG-E5803.
The purpose of this trial is to investigate whether treatment with this new drug will result in lower testosterone levels in men with prostate cancer. At the same time it will be investigated whether the drug induces side effects, and if so, which ones.
The purpose of this study is to test the safety of ketoconazole and how well it works after chemotherapy has been used. Ketoconazole at lower doses has been used for fungal infections however has not yet been approved by the Food and Drug Administration for use in prostate cancer. Ketoconazole has been used for many years at high doses for prostate cancer, and this study will be to look at use of lower dose ketoconazole after someone has received chemotherapy. Ketoconazole works by halting the production of steroids in your body, including testosterone, and is thought to work directly on prostate cancer cells in published lab studies.
RATIONALE: Vitamin E supplements may stop or delay the development of prostate cancer in patients who are at risk of prostate cancer or who have prostate cancer. It is not yet known which vitamin E regimen is more effective in preventing prostate cancer. PURPOSE: This randomized phase I trial is comparing vitamin E supplement regimens to see how well they work in preventing cancer in patients at risk of prostate cancer or who have prostate cancer.
1. To assess the safety of using the CONTINUUM™ device by monitoring the side effects and complications associated with the Device following a radical prostatectomy. 2. To verify CONTINUUM™ device performance using updated CONTINUUM™ device design modifications, physician procedure guide and training methodology.
The primary objective of this study is to evaluate the prediction of late toxicity by the radiation induced CD8 T-lymphocyte apoptosis
RATIONALE: The use of diindolylmethane, a substance found in cruciferous vegetables, may slow the growth of tumor cells. PURPOSE: This phase II trial is studying how well diindolylmethane works in treating patients with stage I or stage II prostate cancer undergoing radical prostatectomy.
