Active clinical trials for "Prostatic Neoplasms"

The aim of this observational study is to show the superiority of the bidirectional barbed suture (Symmcora® Longterm) in terms of time to perform the vesicourethral anastomosis after robot assisted radical prostatectomy compared to the available literature data, without an increase in the complication rate.

Taking part in clinical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This research will admit a wide range of data on the clinical study experience of metastatic prostate cancer patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future patients with metastatic prostate cancer.

The objective of this study is to evaluate the predictive value of TMPRSS2-ERG gene fusion in patients with prostate cancer treated with radiation and hormonal therapy.

A pilot study with a group of up to 10 men with CRPC about to embark on a 6-month course of treatment with radium 223. Study participants will undergo anatomical MR imaging combined with the new hyperpolarized MRI (1 hour exam) prior to treatment.

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 study is designed to investigate the toxicity and pharmacokinetics (PK) of 2-weekly and 3-weekly docetaxel in metastatic hormone-sensitive prostate cancer (mHSPC). Also, a mechanism-based population pharmacokinetics/pharmacodynamics (PK/PD) model will be developed to provide a better understanding of the complex relationships between the drug exposure and toxicity profiles of docetaxel in mHSPC.

To predict prostate cancer and its prognosis by ultrasound radiomics in ultrasound fusion prostate targeted biopsy.

The purpose of this study is to determine the ability of several new MRI techniques (MR elastography, dynamic contrast-enhanced MRI with gadofosveset, and oscillating gradient diffusion) to determine the location, size, and grade of prostate carcinoma. Thirty patients with biopsy proven carcinoma awaiting prostatectomy will be included in the study. Ex-vivo MRI will also be conducted on the prostate specimen to obtain high resolution imaging correlates to both in-vivo MRI and whole mount prostatectomy specimens. The investigators hypothesize that the addition of these three techniques will increase the accuracy, sensitivity, and specificity of MRI for detecting clinically significant prostate cancer.

Prostate cancer is the most common cancer and the second-leading cause of cancer death amongst men in the United States. Sonoelastography is an imaging technology predicated on reproducible differences in the backscattered ultrasound signal produced by compression of tissues of varying stiffness. It permits measurement of the elastic properties of tissue. These measurements can be transposed onto conventional anatomic ultrasound images, producing a colorized overlay that allows direct visualization of the anatomic distribution of tissue stiffness. In this study, we aim to determine whether prostate biopsies planned with sonoelastographic guidance would be more likely than random prostate biopsies to intersect with foci of carcinoma in the prostate gland, and to determine whether prostate biopsies planned with sonoelastographic guidance would be more likely than random prostate biopsies to yield histopathology representative of the final Gleason Score obtained at pathologic assessment of the resected prostate.
