211 Clinical Trials for Various Conditions
This research study is evaluating whether a standard prostate MRI examination can improve radiation therapy planning for prostate cancer.
This is a psychosocial/behavioral study and does not involve administration of any treatment or diagnostic procedures. We will use a randomized trial to test the hypothesis that a decision analysis model that provides individualized estimates of quality-adjusted disease-free survival for each of the treatment options for clinically localized prostate cancer will lead to higher quality treatment decisions congruent with a patient's values leading to improved decisional regret and treatment satisfaction. In this trial, all patients would be evaluated at baseline for their utilities for various clinically important health states. The control arm will receive counseling regarding treatment options using standard patient-physician interactions and nomogram-predicted probabilities of treatment outcome for the various treatment options and they will be unaware of the decision analysis recommendation. The treatment arm would be counseled using standard patient-physician interactions and they would also be provided with a personalized treatment recommendations based on the decision analysis model prior to treatment selection. The primary endpoint of this study will be regret-free survival at 2 years after treatment. There will be a 1:1 randomization. A random permuted design will be used to assure approximate balanced number of patients in the two groups over time.
This randomized phase III trial studies how well stereotactic body radiation therapy works compared to intensity-modulated radiation therapy in treating patients with stage IIA-B prostate cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Stereotactic body radiation therapy may work better in treating patients with prostate cancer.
This phase II trial studies how well gallium Ga 68-labeled gastrin-releasing peptide receptor (GRPR) antagonist BAY86-7548 (68Ga-RM2) positron emission tomography (PET)/computed tomography (CT) works in detecting regional nodal and distant metastases in patients with intermediate or high-risk prostate cancer. 68Ga-RM2 PET/CT scan may be able to see smaller tumors than the standard of care CT or magnetic resonance imaging scan.
This randomized phase II trial studies how well androgen receptor antagonist ARN-509 works with or without abiraterone acetate, gonadotropin-releasing hormone agonist, and prednisone in treating patients with high-risk prostate cancer undergoing surgery. Androgen can cause the growth of prostate cancer cells. Hormone therapy using androgen receptor antagonist ARN-509, abiraterone acetate, and gonadotropin-releasing hormone analog (GnRH agonist) may fight prostate cancer by lowering the levels of androgen the body makes. Prednisone may either kill the tumor cells or stop them from dividing. Giving androgen receptor agonist ARN-509 with or without abiraterone acetate, GnRH agonist and prednisone may work better in treating patients with prostate cancer.
This phase II trial studies how well apalutamide, abiraterone acetate, prednisone, degarelix, and indomethacin work in treating patients with prostate cancer that has spread from where it started to nearby tissue or lymph nodes before surgery. Androgen can cause the growth of tumor cells. Hormone therapy using apalutamide, abiraterone acetate, prednisone, degarelix, and indomethacin may fight prostate cancer by lowering the amount of androgen the body makes and/or blocking the use of androgen by the tumor cells.
This phase 2-3 trial studies the utility of 68-gallium (68Ga)-prostate-specific membrane antigen 11 (PSMA-11) positron emission tomography/magnetic resonance imaging (PET/MRI) to find tumors in patients with prostate cancer who are undergoing resection surgery for prostate cancer that is prognostically expected to spread quickly (intermediate-risk) or is likely to come back or spread (high-risk). Diagnostic procedures, such as PET/MRI, may help find and diagnose prostate cancer, and reveal out how far the disease has spread. Radioactive drugs, such as 68Ga-PSMA-11, may bind to tumor cells that have specific receptors, and may allow doctors to see smaller tumors than the standard of care contrast-enhanced computed tomography (CT) or MRI scan.
This phase I trial studies the side effects and the best dose of hypofractionated stereotactic body radiation therapy (SBRT) in treating patients with prostate cancer that was removed by surgery. Hypofractionated SBRT delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and may have fewer side effects than standard radiation therapy.
This pilot clinical trial studies targeted biopsies in determining response in patients with prostate cancer undergoing high-dose-rate brachytherapy (a type of radiation therapy in which radioactive material sealed in needles, seeds, wires, or catheters is placed directly into or near a tumor). Studying tumor tissue obtained before and after treatment may help doctors understand changes in a pathway that looks at how deoxyribonucleic acid (DNA) is repaired after it is damaged and to see if there are differences in the prostate tissue prior to and after starting androgen deprivation therapy.
This phase II trial studies how well stereotactic body radiation therapy works in treating patients with prostate cancer that has not spread to other parts of the body and have undergone surgery. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue.
This randomized phase III trial studies how well hypofractionated radiation therapy works compared to conventional radiation therapy after surgery in treating patients with prostate cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Conventional radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. It is not yet known whether giving hypofractionated radiation therapy or conventional radiation therapy after surgery may work better in treating patients with prostate cancer.
This randomized phase II/III trial studies docetaxel, antiandrogen therapy, and radiation therapy to see how well it works compared with antiandrogen therapy and radiation therapy alone in treating patients with prostate cancer that has been removed by surgery. Androgen can cause the growth of prostate cells. Antihormone therapy may lessen the amount of androgen made by the body. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving antiandrogen therapy and radiation therapy with or without docetaxel after surgery may kill any remaining tumor cells.
This phase I trial studies stereotactic body radiation therapy (SBRT) in treating patients with prostate cancer that is likely to come back or spread (high-risk) undergoing surgery. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Delivering radiotherapy before prostatectomy by SBRT is more convenient, conformal, and may spare normal tissues better than delivering radiotherapy after prostatectomy.
This phase I trial studies the side effects and best dose of multitargeted tyrosine kinase inhibitor PLX3397 (PLX3397) when given together with radiation therapy and antihormone therapy in treating patients with prostate cancer that is at intermediate or high risk of spreading. Multitargeted tyrosine kinase inhibitor PLX3397 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth, and may also help the radiation therapy work better. Radiation therapy uses high-energy x-rays to kill tumor cells. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as leuprolide acetate, goserelin acetate, or degarelix, may lessen the amount of androgens made by the body. Giving multitargeted tyrosine kinase inhibitor PLX3397 with radiation therapy and antihormone therapy may be a better treatment for prostate cancer.
This phase I/II trial studies the side effects and best dose of stereotactic body radiation therapy while using intensity-modulated radiation therapy (IMRT) planning to help avoid radiation to normal tissue in patients with prostate cancer. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using small, high doses of radiation over several days and may cause less damage to normal tissue. This treatment schedule allows for a higher dose of radiation to be administered over a shorter overall treatment period in comparison to standard radiation therapy.
This randomized phase II trial studies how well PROSTVAC (prostate-specific antigen \[PSA\]-TRICOM) works in preventing disease progression in patients with prostate cancer undergoing active surveillance. Vaccines made from a person's tumor cells may help the body build an effective immune response to kill tumor cells that express PSA.
This phase II trial studies the side effects and how well hypofractionated proton beam radiation therapy works in treating patients with prostate cancer that has not spread to nearby lymph nodes or to other parts of the body. Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.
This phase II trial studies how well itraconazole works in treating patients with biochemically relapsed prostate cancer. Itraconazole may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This phase II trial studies how well radiation therapy with or without apalutamide works in treating patients with prostate cancer that has come back (recurrent). Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgen can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may lessen the amount of androgen made by the body. Giving radiation therapy and apalutamide may work better at treating prostate cancer compared to radiation therapy alone.
This phase II trial studies genetic and molecular mechanisms in assessing response in patients with prostate cancer receiving enzalutamide therapy. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as enzalutamide, may lessen the amount of androgens made by the body. Studying samples of tissue and blood in the laboratory from patients with prostate cancer may help doctors better understand castration-resistant prostate cancer. It may also help doctors make improvements in prostate cancer treatment.
This randomized phase IIA trial studies how well antiandrogen therapy works with or without axitinib before surgery in treating patients with previously untreated prostate cancer that is known or suspected to have spread to lymph nodes. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as antiandrogen therapy may lessen the amount of androgen made by the body. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known if antiandrogen therapy is more effective with or without axitinib before surgery in treating patients with prostate cancer.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent or delay the development of early cancer. Soy isoflavones may be effective in delaying the development of early prostate cancer. PURPOSE: This randomized phase II trial is studying different regimens of soy isoflavones to compare how well they work in treating patients who are undergoing radical prostatectomy for stage I or stage II prostate cancer (adenocarcinoma).
This phase III trial tests the side effects of stereotactic body radiation therapy (SBRT) compared to hypofractionated radiotherapy for treating patients with prostate adenocarcinoma that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to a limited number of sites (oligometastatic). SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumors cells and have fewer side effects. SBRT may work just as well as hypofractionated radiation therapy at treating patients with biochemically recurrent or oligometastatic prostate cancer, but with a shorter treatment time and possibly fewer side effects.
This phase II trial investigates the effect of high dose-rate brachytherapy and stereotactic body radiotherapy in treating patients with prostate adenocarcinoma. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. 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.
This clinical trial studies the side effects of computed tomography (CT)-guided stereotactic body radiation therapy (SBRT) with intrafraction motion monitoring and to see how well it works in treating patients with prostate cancer that has not spread to other parts of the body (localized). In CT-guided SBRT, x-ray-based imaging and cone-beam CTs are used to define and localize the area to be treated with SBRT. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. A recent randomized trial showed that while SBRT is associated with less urinary incontinence and erectile dysfunction than complete surgical removal of the prostate, there are more urinary irritative side effects and more bowel side effects than with surgery. One source of uncertainty in SBRT that may contribute to genitourinary (GU) and gastrointestinal (GI) side effects is the necessity of treating a "margin" of volume around the prostate to account for its movement during SBRT. Intrafraction motion monitoring is any technique or system designed to track the movement of the body and target during fractions of external beam radiation to keep the beam on target. This allows for the patient to be repositioned, if needed, to ensure delivery of the SBRT to only the planned treatment area. CT-guided SBRT with intrafraction motion monitoring may lower GU and GI side effects by allowing tighter margins, as has been demonstrated with magnetic resonance imaging (MRI)-guided SBRT.
This clinical trial evaluates changes in quality of life after two treatments with near margin-less adaptive radiation therapy (ART) compared to five treatments with standard stereotactic ablative body radiotherapy (SABR) in patients with prostate cancer that has not spread to other parts of the body (localized). ART is a type of radiation therapy that uses information gathered during the treatment cycle to inform, guide, and alter future radiation treatments with respect to location and dose. It may be able to deliver radiation to the site of disease over a shorter time and with smaller margins (less treatment delivered to nearby healthy tissues). SABR is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Shorter duration near margin-less ART may be just as effective at treating patients with localized prostate cancer but have less quality of life side effects than standard SABR.
This phase II trial evaluates apalutamide in combination with image-guided stereotactic body radiation therapy (SBRT) for the treatment of patients with prostate cancer. Prostate cancer usually needs the hormone testosterone to grow. Apalutamide is a hormone therapy that blocks the effect of testosterone on prostate tumor cells. This may help stop the growth of tumor cells that need testosterone to grow. Image-guided SBRT is a standard treatment for some types of prostate cancer. This treatment combines imaging of cancer within the body, with the delivery of therapeutic radiation doses produced on a linear accelerator machine. SBRT 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. Combining apalutamide with image-guided SBRT may increase a prostate cancer patient's chances of achieving an extremely low prostate specific antigen response, which is an early predictor of disease cure.
This clinical trial studies the effects of a dietary intervention prior to surgery (neoadjuvant) in patients with intermediate risk prostate cancer. Changing your diet before surgery may help to improve overall health. Information from this study may help researchers better understand the influence of diet on the outcomes of patients with intermediate prostate cancer.
This trial studies the changes in long-term physician-scored genitourinary toxicity achieved in prostate cancer patients eligible for stereotactic radiation therapy when both patients and physicians have access to convincing but non-validated germline signature that can characterize patients as having a low or high risk of developing toxicity after radiation therapy. The information learned from this study may guide patients' and physicians' decisions on radiotherapy fractionation.
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.
