48 Clinical Trials for Various Conditions
This is a pilot evaluation of a patient-centered intervention that enables providers to support men on active surveillance to maximize adherence. Conducted in urology practices, this pilot will measure key patient-reported, provider-reported, and implementation outcomes. Successful completion of this work will inform a subsequent multi-center effectiveness-implementation hybrid design trial and ultimately will improve low-risk cancer management by effectively engaging Primary Care Physicians (PCPs) in care delivery.
This is a prospective study to determine if the use of curcumin randomized against placebo will reduce cancer progression in patients with prostate cancer undergoing active surveillance.
The purpose of this study is to evaluate the effects of Noni extract in men diagnosed with very low risk or low risk prostate cancer
The purpose is to determine if use of rectal spacers are effective at improving protection of rectum from high dose radiation, using rate of rectal ulceration as a surrogate measure of acute effects. It is also to determine whether it provides sufficient dosimetric benefits to warrant further clinical investigation in future SABR (Stereotactic Ablative Body Radiation) related clinical studies.
The standard options for men with very low risk prostate cancer include active surveillance and the standard treatment options for low risk disease, i.e. radical prostatectomy, external beam radiotherapy, and whole gland prostate brachytherapy. The present study seeks to evaluate focal brachytherapy using the isotope Cesium 131 to treat patients with low risk prostate cancer. The goals of the study are to determine the biochemical disease free survival at five years in these patients, as well as to determine the acute and late urinary, bowel, and sexual toxicity associated with focal prostate brachytherapy using Cesium 131. Patients eligible for the study will be men with histologically confirmed adenocarcinoma of the prostate with clinical stage T1c-T2aN0M0, Gleason score ≤3+3=6, prostate specific antigen(PSA) \<10 ng/ml or a PSA density ≤ 0.15 ng/cc, and ≤ 2 cores positive out of a minimum of 12 cores sampled. Additionally, patients must have a single, dominant index lesion on MRI. The study is a phase II study. Patients will be followed prospectively. Dosimetry will be evaluated post-procedure, and PSAs will be obtained every three months in year one and every six months from year two through year five. Urinary, bowel, and sexual morbidity will be assessed by patient survey prior to treatment , two weeks, after treatment, at three month intervals in year one and at six month intervals in years two through five.
This randomized phase II trial studies how well green tea extract works in treating patients with low-risk prostate cancer. Green tea extract contains ingredients that may prevent or slow the growth of certain cancers.
A prostate cancer diagnosis starts a list of events that often leads to fast-moving treatment, thought by many to result in vast over-treatment of this disease. So, discovery of different diagnostic methods that allow clinicians to identify slow-growing from potentially fast-growing disease prior to or at the time of prostate biopsy could result in early and suitable treatment for men at greatest risk, while greatly decreasing the number of biopsies, surgical procedures, hormonal and chemotherapeutic treatments, cost, and patient worry, for those with more slow-growing disease.
Vitamin D promotes the differentiation of prostate cancer cells and maintains the differentiated phenotype of prostate epithelial cells. The results of the investigators' clinical studies indicate that vitamin 1,25 dihydroxyvitamin D3 (VD3) supplementation results in a decrease of positive cancer cores at repeat biopsy in subjects with low-risk prostate cancer. The investigators hypothesize that Veterans who have early-stage prostate cancer and who take vitamin D3 at 4000 international units per day (intervention group) will show an improvement in the number of positive cores and in Gleason score at repeat biopsy, and a decreased likelihood of undergoing definitive treatment (prostatectomy or radiation therapy), compared to Veteran subjects taking placebo (control group).
This study will evaluate the usefulness of an informational website designed to educate patients with prostate cancer about their options for treatment. The investigators hope that this website will assist patients with making informed decisions about their care and improving their satisfaction with the treatments they choose.
The purpose of this research study is to monitor the feasibility and outcome of the Active Surveillance Program for men with low risk prostate cancer.
The purpose of this study is to compare the effects (good and bad) on patients with prostate cancer by comparing the standard dose of radiation therapy (44 treatments over 8½-9 weeks) with a higher daily dose of radiation (5 treatments over 1-2 weeks) to see if the effects of the treatments are similar or better.
The purpose of this study is to find out if men, with low-risk prostate, can have the small amount of cancer within their prostate removed by freezing, called Focal Cryoablation or Cryotherapy.
RATIONALE: Diagnostic procedures, such as MRI and magnetic resonance spectroscopy imaging, may help in learning how well dutasteride works in patients with benign prostatic hypertrophy and low-risk prostate cancer. PURPOSE: This clinical trial is studying MRI and magnetic resonance spectroscopy imaging in patients receiving dutasteride for benign prostatic hypertrophy and low-risk prostate cancer.
Objective: To test the hypothesis that the shorter half-life of Pd-103 versus I-125, will increase the rate of tumor eradication. Research design A total of 600 patients with AJC clinical stage T1c-T2a prostatic carcinoma (Gleason grade 2 to 6, PSA 4 to 10 ng/ml) will be randomized to implantation with I-125 (160 Gy) versus Pd-103 (115 Gy).
The purpose of this study is to collect information on how patients and their partners/close allies make treatment decisions when they have been diagnosed with early stage prostate cancer.
Phase II non-inferiority randomized trial of annual systematic biopsies versus mpMRI and targeted biopsies for men with low risk prostate cancer on active surveillance with any volume Gleason's Score 6, but no prior MRI imaging of the prostate.
This study is being proposed to evaluate the use of moderate hypofractionated proton therapy in low and intermediate risk prostate cancer patients. Quality of life outcomes as well as gastrointestinal and genitourinary early and late toxicities will be analyzed and compared to conventional proton therapy regimens. It is thought that this regimen will produce comparable findings and would result in substantial health care cost savings, as well as, be more convenient for patients.
The primary safety purpose of this study is to estimate the rates of immediate and long-term high grade (grade 3-5) gastrointestinal and genitourinary side effects during the five years after TrueBeam stereotactic body radiotherapy in low-risk and intermediate-risk prostate cancer patients. The primary efficacy purpose is to compare 5 year biochemical disease free survival rates with TrueBeam to 5 year biochemical diseases free survival rates with dose-escalated external beam radiation therapy.
The purpose of this study is to determine whether stereotactic body radiation therapy (SBRT) with simultaneous boost (higher radiation dose) to areas within the prostate with more prominent cancerous growth (intraprostatic lesions) utilizing intensity modulated radiotherapy (IMRT) planning techniques is a safe and effective treatment in patients with low- and intermediate-risk localized prostate cancer.
This randomized phase III trial studies a diet and exercise program based on the Diabetes Prevention Program to promote weight loss and improve health in men with low-risk or low-intermediate-risk prostate cancer on active surveillance. A lifestyle intervention that promotes weight loss may influence prostate health. A combined diet and exercise program that is based on the Diabetes Prevention Program may affect markers (or "biomarkers") of prostate cancer progression. Gathering this information may help doctors understand how obesity affects prostate cancer progression and may help lead to a program that can reduce the risk of prostate cancer progression.
The purpose of this study is to investigate the effects of CyberKnife radiosurgery in patients with early stage organ-confined prostate cancer and to evaluate the effects of this treatment on the quality of life over time.
The purpose of this study is to examine the effect of dutasteride on the inhibition of low-risk, localized prostate cancer progression in men who would otherwise receive no active therapy (expectant management).
The purpose of this study is to determine the substantial equivalence of the Ablatherm high intensity focused ultrasound (HIFU) as compared to cryotherapy for the treatment of low risk, localized prostate cancer.
This phase II trial studies how well focal radiation therapy with stereotactic body radiation therapy (SBRT) or high-dose rate (HDR) brachytherapy works in treating patients with low or intermediate-risk prostate cancer. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. HDR brachytherapy uses high doses of radiation to target these tumor cells. Giving focal radiation therapy with SBRT or HDR brachytherapy may target dominant tumor cells while sparing the reminder of the prostate or surrounding normal organs and ultimately reduce side effects while maintaining disease control.
The purpose of this study is to determine the side effects and how effective CyberKnife stereotactic ablative body radiation (SABR) is in patients with prostate cancer. The CyberKnife system is a new type of radiation machine that uses a special system to precisely focus large doses of x-rays on the tumor. The device is designed to concentrate large doses of radiation onto the tumor so that injury from radiation to the nearby normal tissue will be minimal. The purpose of this evaluation is to see if this treatment will help patients with low to intermediate risk prostate cancer and to evaluate the effect of this treatment on the patients' quality of life over time.
This clinical trial studies stereotactic body radiation therapy in treating patients with low- and intermediate-risk prostate cancer. Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue.
This study is designed to evaluate the safety and efficacy of a single injection of NX-1207 for the treatment of biopsy-confirmed low risk localized (T1c) prostate cancer in patients currently undergoing active surveillance. Study participants currently on active surveillance will be randomized either to treatment with a single intraprostatic injection of NX-1207 (2.5 mg or 15 mg) followed by active surveillance or to no treatment (continued active surveillance). Blinded efficacy evaluation will be by a second post-treatment prostate biopsy.
We are studying whether men being treated for prostate cancer have the same amount of side effects from either one of two different external radiation treatments: IMRT or PBT. With IMRT, a number of x-ray beams are used to shape the radiation to the prostate. PBT is another type of external radiation treatment for prostate cancer that is used in a few centers in the United States. Protons are tiny particles with positive charge that can be controlled to travel a certain distance and stop. PBT is precise like IMRT, but it uses proton beams instead of x-ray beams. IMRT and PBT aim to deliver most of the radiation to the prostate cancer while sparing surrounding tissues. Both IMRT and PBT have been used in the treatment of prostate cancer and are thought to be equally effective at curing prostate cancer. However, both treatments have also been shown to cause the potential side effects of radiation, including bowel, urinary and erectile problems. It is possible that side effect rates with PBT will be lower, the same, or even higher than with IMRT, but this has not been studied well to date. Though both of these radiation therapies have been used in the past to treat prostate cancer, there has never been a study that compares the effects of these two therapies to see which one has less side effects. In this research study, we are comparing IMRT to PBT to determine which therapy best minimizes the side effects of treatment.
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.
The purpose of this study is to see how safe Androderm® (the study drug) is at three different doses in subjects with early hormone refractory prostate cancer. In addition, information about hormonal levels and the effects of testosterone on quality of life including sexual functioning and muscle strength will be collected.
