Active clinical trials for "Prostatic Neoplasms"

The objective of this study is to assess the effect of neoadjuvant cabazitaxel and pelvic radiotherapy in combination with androgen deprivation therapy (ADT)-radiotherapy on clinical progression-free survival in patients with high-risk localized prostate cancer (with a stringent selection of patients with at least 2 high-risk features), in a 2 by 2 factorial trial.

To determine if the addition of radium-223 dichloride to standard treatment is able to prolong life and to delay events specific for prostate cancer which has spread to the bone, such as painful fractures or bone pain which needs to be treated with an X-ray machine.

This study will ultimately aim to evaluate the side effects of treatment by asking 20 subjects to receive post-operative radiotherapy for prostate cancer with the treatment plan adapted after the first week of treatment to account for changes in the target shape. These patients will be asked to complete toxicity scores and a quality of life questionnaire at the start and completion of treatment, and at 3 months 1, 2 and 5 years from the start of radiotherapy. These results will be used to determine the feasibility of the proposed approach, and obtain early estimates of improvements in uncertainty margin requirements for this population of patients.

Since high risk prostate cancer requires higher radiation, this study is being done to determine the maximum tolerated dose of radiation to the prostate and pelvic regions. Also to determine the feasibility and safety of each treatment fraction by using cone-beam Computed Tomography(CT) information and high speed Graphics Processing Unit based computation treatment planning systems. We also plan to determine the safety of treatment to the prostate. Health-related quality of life will be measured as part of current clinical practice. Determine the maximum tolerated dose (MTD) or to safely escalate dose to the pelvic nodal using 90 day acute toxicity endpoint Determine feasibility and safety of adaptive real time re-planning of the pelvic nodal region at each treatment fraction by using cone-beam CT (CBCT) information and high speed GPU based computation treatment planning systems Determine the safety and tolerability of 9.5 Gy per fraction in five fractions (47.5 Gy total dose) to the prostate Determine the feasibility and safety of temporal enhanced ultrasound for prostate lesion tracking during radiation therapy To follow tumor related outcomes (i.e. PSA control, progression-free survival (PFS), distant metastasis (DM) free survival, and overall survival (OS) Health-related quality of life (HRQOL) will be measured as part of current clinical practice Patients in each dose cohort will all be treated as a single group for dose escalation. There will be two levels of dose escalation-to prostate lesions and to pelvic lymph node region. Prostate/SV PTV will be treated at a fixed dose of 9.5 Gy per fraction for 5 fractions (47.5 Gy) based on our previous phase I/II study experiences. The starting dose for the dose escalation to the pelvic region PTV will be 4.5 Gy per fraction for 5 fractions (total dose= 22.5 Gy). Subsequent cohorts of patients will receive an additional 0.5 Gy per treatment (total 2.5 Gy per escalation). The starting dose for MRI-visible prostatic lesions will be 10 Gy and subsequent cohorts will receive an additional 0.5Gy per treatment (total of 2.5Gy per escalation).

Purpose of the study was to assess the effect of enzalutamide on time to Prostate Specific Antigen (PSA) progression as compared to placebo in chemotherapy naïve participants with progressive metastatic prostate cancer who have failed androgen deprivation therapy.

This clinical trial studies stereotactic body radiation therapy in treating patients with high-risk prostate cancer that has not spread to nearby lymph nodes or to other parts of the body. Stereotactic body radiation therapy is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may kill more tumor cells and cause less damage to normal tissue. Studying quality of life in patients undergoing stereotactic body radiation therapy may help identify the long-term effects of treatment on patients with prostate cancer.

The aim of the study is to investigate, the effect of radical prostatectomy with extended lymphadenectomy on cancer-specific survival, time to castration-resistance, time to progression and quality of life in patients with a limited bone metastatic prostate cancer. In addition the influence of patient- and disease-related factors on clinical outcome (prognostic effect) and on the comparison therapy (predictive effect) will be examined. Amendment05: Due to the slow tumor biology of prostate cancer, the follow-up period of 5 years is not sufficient to reach the primary endpoint of the study. For this reason, the follow-up is extended for a further 5 years with 2 visits per year.

The purpose of this study is to find out the effects (good and bad) of using newer technologies that allow very precise delivery of radiation. These newer technologies are Intensity Modulated Radiation Therapy (IMRT) and Image Guided Radiation Therapy (IGRT).

To determine if supervised high intensity aerobic and resistance training increases overall survival compared to self-directed exercise in patients with metastatic prostate cancer.

The purpose of this study is to determine whether anti-testosterone medications, when administered before, during, and after high-dose, precision radiation, will be effective in preventing the prostate cancer from returning.
