Active clinical trials for "Prostatic Neoplasms"

Robotic prostatectomy is a surgery for treating localized prostate cancer. The ARssist system is a novel augmented reality system designed for the assistant surgeon, allowing delivery of augmented reality information via Microsoft HoloLens 2 (a head mount display developed by Microsoft) to better delineate the 3-D operative environment and enable better visualization. To date, there is no prospective study on the clinical performance and utilization of the ARssist system. This study is to evaluate the clinical feasibility and safety of the ARssist system during robotic surgery with the da Vinci Xi system.

The purpose of this study is to assess the effect of the addition of metformin to abiraterone on survival in patients with newly diagnosed metastatic hormone-sensitive prostate cancer. The half the patients will receive metformin in combination with androgen deprivation therapy (ADT) and abiraterone, and the other half will receive ADT and abiraterone only.

This prospective registry aims to assess outcome and toxicity of targeted radionuclide therapies in patients with advanced prostate cancer in clinical routine. While the major investigated treatment modality is prostate-specific membrane antigen (PSMA)-targeted radioligand therapy, also other radionuclide therapies such as Ra223 and liver-directed radioembolization are included. The investigators believe that prospectively assessed long-term outcome data on implementation of radionuclide therapy, especially in the palliative setting of advanced mCRPC, help to better define the real benefits and risks of the respective treatment modalities for patients regarding survival and quality-of-life.

This exploratory study conducted under the RDRC program studies the biodistribution of 99mTc-PSMA-I&S in patients with prostate cancer who undergo pelvic lymph node dissection. Prostate specific membrane antigen (PSMA)-targeted radio-guided surgery uses the preoperative intravenous administration of a PSMA-ligand called PSMA-imaging and surgery (I&S) labeled with the gamma-emitter radioisotope Technetium-99m (99mTc). Giving 99mTc-PSMA-I&S may detect PSMA-expressing lymph nodes during surgery using a gamma probe and may help guide doctors to detect prostate cancer that has spread to the lymph nodes.

This intervention includes the introduction of the Prostate Cancer Working Group (PCWG )Smart PSA Screening Guidelines and implementation of patient navigation/ care coordination for men with elevated PSA (>4.0 ng/mL). The guidelines include: What age to start? How often to repeat screening? What age to stop? What PSA threshold should trigger a biopsy referral?

This trial studies how well a peer-based health education program works in reducing barriers and changing attitudes and beliefs of prostate cancer genetic screening in African American participants with or without a previous personal or family history of prostate cancer. Participating in a peer-based health educational program may help participants learn more about prostate cancer and how their personal or family history of disease may increase their risk of prostate cancer.

A multi-center, prospective active surveillance registry trial assessing the performance of a non-invasive blood test for indolent prostate cancer disease management.

This randomized pilot phase I trial studies the best way, either expressed prostatic secretion (EPS) or post massage urine (PMU) biomarkers, of predicting biopsy results in patients undergoing prostate biopsy. Studying samples of urine in the laboratory may help doctors detect prostate cancer. It is not yet known whether EPS or PMU biomarkers are more effective in predicting prostate biopsy results

Prostate cancers, in common with many other tumours, are often hypoxic; that is, they have low levels of oxygen. It is thought that tumour hypoxia may hasten the progression of cancers and make them more resistant to treatment. One previous study has suggested that hormone therapy, such as Casodex, may improve the prostate oxygen level. This study is designed to test that finding.

The Prostate Active Surveillance Study (PASS) is a research study for men who have chosen active surveillance as a management plan for their prostate cancer. Active surveillance is defined as close monitoring of prostate cancer with the offer of treatment if there are changes in test results. This study seeks to discover markers that will identify cancers that are more aggressive from those tumors that grow slowly.
