Active clinical trials for "Prostatic Neoplasms"

The primary objective of this study is to assess disease response to Doxil in patients with hormone refractory prostate cancer with or without dexamethasone pre-treatment. Study Design: We will perform an open labeled, parallel, randomized phase II study using a two-stage design to determine if there is sufficient anti-tumor activity in either arm to warrant further study. Assumptions made in this study: an unacceptable overall response rate is </= 10% & we will pursue further study if the overall response rate is >/= 30%. Fifteen patients will be randomized in the first phase (to both Arm 1 and Arm 2). No further patients will be accrued if <2/15 responses are noted in a given arm. Ten additional patients will be enrolled if >/= 2/15 responses are observed. If there are >/= 5/25 responses then further studies will be pursued with that regimen. We will determine the overall incidence & severity of toxicities in both arms. Treatment: Arm 1: Doxil: Dose: 50 mg/m2, IV (in the vein) on day 5 of each 28 day cycle. Arm 2: Doxil: Dose: 50 mg/m2, IV (in the vein) on day 5 of each 28 day cycle. Arm 1 only: Dexamethasone: Dose: 12 mg twice a day by mouth on days 1, 2, 3, 4, 5 of each 28 day cycle. Number of Cycles for both Arm 1 & 2: until progression or unacceptable toxicity develops.

The purpose of this study is to determine if patients who take YM598 in addition to mitoxantrone and prednisone (standard therapy) experience improvement in the pain associated with prostate cancer metastases in the bone.

This is a prospective data collection of men who are electing to undergo prostate hemi-gland cryoablation. The purpose of this observational research study is to investigate the localized treatment of prostate cancer using hemi-gland cryoablation. UCLA patients undergoing hemi-gland cryoablation are a unique cohort compared to prior research because all patients at UCLA have had a pre-treatment multi-parametric MRI and Ultrasound fusion targeted biopsy; they will be followed in a similar fashion. This results in more precise assessment of a target region of cancer for ablation which may, in turn, result in improved clinical outcomes.

This phase III trial compares the use of contrast-enhanced multiparametric ultrasound (mp-US) to multiparametric magnetic resonance imaging (mp-MRI) for the diagnosis of clinically significant prostate cancer (PCa). A mp-US is a procedure in which a probe that sends out high-energy sound waves is inserted into the rectum. The sound waves are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissue called a sonogram. Perflutren lipid michrosphere (Definity) is a contrast agent that uses microbubbles to enhance ultrasound images of the prostate. Doctors hope to learn if the Definity-enhanced mp-US imaging technique can accurately direct targeted biopsy for the detection of clinically significant prostate cancer when compared to standard of care mp-MRI.

The PROMOD study is an international multicenter retrospective Project. The aim is to create a comprehensive database that will include multiple heterogeneous cohorts in order to explore inter-center differences in the accuracy of Magnetic Resonance Imaging (MRI) in the diagnosis of prostate cancer and to define optimal strategies for the selection of men at risk of clinically significant prostate cancer who might benefit from biopsies.

The purpose of this study is to investigate the usefulness of PET/MRI with an investigational radioactive drug, 18F-rhPSMA-7.3, and MRI contrast in evaluating patients with prostate cancer eligible for active surveillance. This study is for imaging purposes only and is not a treatment study.

The investigators conduct a random assignment into either the remimazolam group or the propofol group. Depending on the group assignment, either remimazolam (0.2 mg/kg) or propofol (1.0 mg/kg) is administered. If necessary, additional doses of remimazolam (0.1 mg/kg) or propofol (0.5 mg/kg) are given. The standard anesthesia procedure of our institution is followed, and blood pressure data recorded during the surgery is analyzed (mean arterial pressure <65mmHg is defined as hypotension).

To investigate whether multiparametric MRI (mp-MRI) in patients with low-risk prostate cancer can improve the selection of patients suitable for Active Surveillance and have a relevance in the ongoing monitoring.

The purpose of this study is to determine the appropriate loading and maintenance dose of GTx-758 to reach and maintain castration for the duration of the study.

The primary objective is to perform a pilot trial evaluation of a novel prostate ultrasound imaging software utilizing tissue elasticity measurements to identify tumor foci among men who will undergo radical prostatectomy for localized prostate cancer. As a secondary objective, investigators will compare elasticity measured tumor foci volume to the measured volume from radical prostatectomy pathologic examination.
