Filter by:RATIONALE: The use of nutritional supplements, such as selenium, may stop prostate cancer from growing. Internal radiation, such as brachytherapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving selenium before brachytherapy may be an effective treatment for prostate cancer. PURPOSE: This randomized phase I trial is studying selenium to see how well it works compared to placebo in treating patients who are undergoing brachytherapy for stage I or stage II prostate cancer.
Docetaxel-based therapy has been shown to prolong survival as first-line therapy for patients with HRPC, and has become the standard of care. The beneficial effects of any therapy in HRPC may be diverse and include reduction in tumor bulk (when measurable), reduction in PSA, reduction in symptoms (particularly pain), or stabilization of disease. Clear reductions in tumor bulk or PSA may provide objective evidence of a treatment effect, and stabilization of disease may be just as clinically meaningful in patients who are actively progressing prior to starting therapy. Pemetrexed has shown a broad array of activity in many diseases that until now were thought to be non-responsive to chemotherapy in the second-line setting. This trial is designed to further assess the efficacy, safety, tolerability, and pharmacogenetics of pemetrexed as a single agent in subjects with HRPC whose disease has progressed following one prior taxane-based chemotherapy regimen for HRPC.
This pilot study is designed to determine the feasibility and safety of administering docetaxel at various dosing levels on a bi-weekly schedule in older men with hormone refractory prostate cancer.
This was an extension study for the study FE200486 CS12 (NCT00819156). Each participant was to be treated until he was discontinued or withdrawn from the study, or a marketing authorization for degarelix had been obtained. The study was terminated when all ongoing participants had been treated for at least 5 years (including one year in the main study).
BACKGROUND: -This study represents a progression from findings in four previous National Cancer Institute (NCI) Radiation Oncology Branch (ROB) protocols (02-C-0167A, 02-C-0207E, 03-C-0190B, 04-C-0171). In these previous works we have begun to develop techniques to obtain Magnetic Resonance (MR) biological images and co-register tissue in prostate cancer patients. OBJECTIVES: -The primary objective of the first portion of this study is to assess the feasibility of using Intensity-modulated radiation therapy (IMRT) to treat the at-risk lymph nodes in prostate cancer. Also, if feasible, we hope optimize this technique with experience. ELIGIBILITY: -This is a study of image guided, targeted radiation therapy in patients with high risk of nodal metastases from prostate cancer. Patients with prostate cancer who have more than 15% risk of lymph node (as defined by the Partin tables) metastasis will be eligible for this study. DESIGN: - On the first 10 patients, we will perform approximately 5 computed tomography (CT) simulations throughout the course of their therapy. On each simulation, the initial treatment plan will be re-run. The dose-volume data from target and normal tissues will then be re-analyzed. From this analysis we will be better able to determine the size of margins needed to account for organ motion and changes such as varying amounts of gas in the bowel and fluid in the bladder. To the best of our knowledge, no such analyses have been published. - If the initial part of this trial is feasible, we will proceed to a phase I dose escalation trial of radiation to the at-risk lymph nodes. The primary statistical objective of the phase I portion of this study is to estimate the Maximum Tolerated Dose (MTD) of external beam radiation based on evaluating acute toxicity. The study will be conducted with a dose-escalation design with 3 patients in each dose cohort. If fewer than 2 of 3 patients experience an acute dose limiting toxicity (DLT) than patients will be accrued to the next dose cohort. If 2 or more of 3 patients experience a DLT then the MTD will be exceeded and the prior, lower dose cohort will be considered the MTD. Secondary objectives of this study are to relate patterns in gene and protein expression to response and toxicity and to evaluate the frequency of late term toxicity. - Specific procedures and risks will be described in a separate consent to be obtained at the time of biopsy. Tissue samples will be processed for complementary deoxyribonucleic acid (cDNA) microarray testing and stored for future analysis in the Radiation Oncology Branch, NCI. - Anatomic Magnetic Resonance Imaging (MRI) and magnetic resonance (MR) biological images of the prostate and pelvis will be obtained and tissue will be acquired with biopsy locations precisely translated (co-registered) to an MR image of reference. A fiducial marker (gold seed) will be left at the biopsy site as a fiducial marker to direct future radiation therapy to the prostate. If necessary, additional fiducial markers will be placed for prostate localization during treatment.
The purpose of this study is to examine the clinical feasibility and efficacy of uing IMRT to escalate the biologically effective dose to the pelvic lymph nodes in a short course of radiation therapy. An increased total and biologically effective dose will be delivered to the pelvic lymph nodes (56 Gy at 2 Gy/fraction). The prostate will receive standard "short course" IMRT of radiation (70 Gy at 2.5 Gy/fraction).
The purpose of this study is to examine the clinical feasibility of using Intensity-modulated radiation therapy (IMRT) combined with daily pretreatment prostate localization to deliver increasingly hypofractionated treatment courses. Progressively larger fraction sizes will be delivered in a phase I design based on both acute and long-term tolerances to the treatment. The dose-per-fraction escalation design utilizes schemas that maintain an isoeffective dose for late effects, while predicting that tumor control will actually improve. The delivery of fewer, larger fractions of radiation, if proven effective and safe, would result in significant cost saving and more efficient use of resources. Phase II will commence with Maximum Tolerated Dose (MTD) finding with up to 200 additional patients being enrolled during this phase of the study.

Prostate cancer is the most common type of cancer among men. It is also the second leading cause of cancer-related death among men. Two screening tests are available to try to detect prostate cancer early – the digital rectal examination (DRE) and the prostate specific antigen (PSA) blood test. Unfortunately, physicians aren’t sure whether or not these two screening tests help save lives, and there’s a lot of controversy about how to use them. Recently, a major government committee (the U.S. Preventive Services Task Force) recommended that physicians discuss the risks and potential benefits of prostate cancer screening with their patients, and allow patients to make their own decision. Because of the controversies, many physicians currently don’t discuss prostate cancer with their patients. The problem is that it takes time and effort to have these discussions, and the information is complicated. A lot of patients have trouble understanding it, especially if they have a limited educational background or trouble reading. When patients have difficulty obtaining, understanding, and acting on basic health information, we say that they have “low health literacy.” Other researchers have shown that patients with low health literacy don’t know as much about cancer screening and are less likely to get screened for various cancers. They also tend to be timid about discussing things with their doctor, and often go along with what the doctor says, rather than taking an active role in the decision making. In 2003, under IRB approval, we conducted a study with 2 goals: 1) to encourage patients to talk to their doctor about prostate cancer screening, and 2) to learn more about the impact of low health literacy on these conversations. To promote conversation, we used two handouts, given to patients in the waiting room before they saw the doctor. The first was a patient education handout about prostate cancer screening, written in very simple terms with useful illustrations. The second was a handout that simply encouraged patients to talk to their doctor about prostate cancer. Patients got one of the two handouts, or a nutritional handout that served as a control. After they saw their doctor, a research assistant briefly interviewed the patient to find out whether or not prostate cancer screening was discussed. We also measured the patients’ health literacy skills, and asked a few other questions about their decision to get screened for prostate cancer.
Randomized clinical study of two CAM therapies, 1) Reiki and 2) Relaxation Response Therapy with Cognitive Restructuring counseling (RRT with CR), compared to an education-only control arm in patients about to begin an eight-week course of external beam radiotherapy (EBRx) for prostate cancer. Generally, we would like to examine the feasibility of studying Reiki and RRT with CR in patients with prostate cancer, and to obtain preliminary results on the effectiveness of these treatments compared to controls. Specific objectives: 1. Determine the proportion of eligible patients who agree to participate in the study 2. Measure compliance with CAM therapy interventions 3. Measure compliance with physiologic and psychological outcome measurement assessments 4. Assess differences between experimental and control groups on measures on depression, anxiety, quality of life, salivary cortisol levels and an immunomarkers
