Active clinical trials for "Prostatic Neoplasms"

The goal of this clinical research study is to evaluate a system for localizing (targeting for treatment) the prostate for external beam radiation therapy. The system will be used to locate the prostate before treatment and to measure movement of the prostate during treatment. The data collected with the system will be compared to CT images taken during the course of your radiation therapy treatment. Researchers will try to use this information to verify the performance of the system, which could lead to improved positioning and tracking of the prostate during treatment.

This study will utilize the Expanded Prostate Cancer Index Composite questionnaire to learn what impact the surgery has upon the participant's sense of health, sexual and urinary quality of life.

Clinical data are being used to build a mathematical model to describe the clinical results of radiotherapy for prostate cancer.

Recently, many centers have begun offering laparoscopic radical prostatectomy (LRP) as a minimally invasive therapy for localized prostate cancer.1-6 LRP may offer the advantages of improved neurovascular bundle sparing, a more precise urethrovesical anastomosis, shorter hospitalization, and decreased convalescence. Our group at Methodist Urology, LLC has extensive experience in laparoscopy and in treating prostate cancer and are planning to offer LRP. We intend to maintain a registry and database to document the outcomes with LRP.

The purpose of this program is to provide access to [Lu-177]-PNT2002 to patients who have been diagnosed with prostate-specific membrane antigen (PMSA)-positive castration-resistant prostate cancer (mCRPC). Patients must have received at least 1 prior androgen pathway inhibitor (ARPI) and cannot be treated by currently available drugs or clinical trials. In this program participants will be administered [Lu-177]-PNT2002 intravenously every 8 weeks (about every 2 months) for 4 cycles, or 8 months of total treatment. During treatment, participants will be monitored with routine laboratory tests such as: Hematology blood tests Clinical Chemistry blood tests Testosterone/Prostate Antigen levels blood test Vital signs Imaging ECG

Single-center evaluation of all patients treated for primary localized prostate cancer with focal HIFU from November 2009 to December 2016. To evaluate midterm oncological outcomes of focal HIFU therapy in low an intermediate risk prostate cancer.

This project's goal is to develop and test an application that uses Artificial Intelligence (AI) to improve consistency and quality of Radiation Treatment (RT) plans for prostate cancer. By understanding expert planner preferences in structure contouring and treatment planning, and combining this framework with planning data and outcomes amassed in NRG clinical trials, AI models may be trained to produce contours and treatment plans that are indistinguishable or even potentially deemed superior to those produced by individual experts. At the conclusion of this contract, the awardees will provide a software product which, when given the input of a description of desired anatomical target volumes and target doses along with a patient's CT scans, will generate target volumes and radiation treatment plans based upon a "gold standard" amalgamated from the input of multiple experts, thereby achieving desired doses to target volumes while meeting or exceeding the dose-volume constraints imposed by adjacent normal tissues.

This study describes how to perform a correct prostatic apex and membranous urethra in order to preserve all anatomical elements that are necessary to achieve a very fast urinary continence after open/laparoscopic/robotic radical prostatectomy, avoiding positive surgical margins at this level.

This prospective registry will evaluate the feasibility and impact of implementing standard cancer family history review and guideline-aligned genetic testing for men diagnosed with Prostate Cancer in community urology practices nationwide.

Rationale: This prospective study investigates the outcomes of daily online stereotactic MR-guided adaptive radiation therapy (SMART) in patients with localized prostate cancer (cT1c-T3bN0M0). Visualization of the prostate, rectum and bladder prior to and during radiation delivery can be used to deliver "gated" treatment (beam-on only when the prostate is in the predetermined position) using small uncertainty margins. The novel MRIdian treatment delivery system (ViewRay, USA), which will be used for this study, allows for the immediate generation of an optimal radiotherapy plan based on the current anatomy of the prostate and surrounding normal organs prior to each fraction. These major advances will (i.e. dosimetrically) allow for an optimisation of normal tissue radiation doses, which should theoretically decrease toxicity to surrounding organs such as the rectum or bladder. Another advantage of this approach is that online MR-based prostate imaging does not rely on implanted gold markers, avoiding an invasive procedure to insert such markers. If proven feasible, this approach could set a new standard of care for patients with localized prostate cancer. The main goal of this phase II study of SMART for prostate cancer is to evaluate the early and early-delayed toxicity, i.e. within the first year after treatment. An established 5-fraction hypofractionated radiation scheme will be used in this trial. Main outcome parameters will include gastro-intestinal, genitourinary and sexual symptoms, which will be monitored at fixed time points using CTCAE criteria. In addition, patient-reported outcomes will be evaluated using EORTC-QOL questionnaires. Objective: To investigate the early and early-delayed toxicity profile of SMART in patients with localized prostate cancer. Study design:phase II observational study Study population: 100 consecutive patients with localized prostate cancer (cT1c-T3bN0M0). Study intervention: Study patients will be treated with an online MR-guided hypofractionated course of radiotherapy in 5 fractions of 7.25 Gy per fraction delivered on the prostate with a simultaneous integrated sparing of the urethra with a dose of 32.5 Gy in 5 fractions Main study parameters: Early and early-delayed toxicity (CTCAE v. 4.0); (IPSS) and Qol C30 PR25. Secondary endpoint will be the offline evaluation of the dosimetric benefit of SMART by comparing cumulative doses to organs at risk.
