Active clinical trials for "Prostatic Neoplasms"

Recurrence free survival The patients will be followed in regular time intervals in accordance with the EAU-Guidelines (2010) and the S-3 Guideline for Prostate cancer of the German Urological Association. Data will be updated once yearly for until death.

This study is being conducted to assess and monitor immune response in patients with minimally symptomatic or asymptomatic hormone refractory prostate cancer who will be receiving Provenge® (Sipuleucel-T) therapy as part of their standard of care treatment regimen.

This protocol is designed to collect a small amount of blood and tissue from individuals with prostate cancer for extraction of DNA (genetic material) for the study of the genetic basis of prostate cancer. The study population will include individuals with known prostate cancer and controls without prostate cancer. The study will be conducted in Doha, Qatar at the Hamad Medical Corporation and Weill Cornell Medical College (Qatar). Individuals in the study population will be of Arab descent from Qatar. In this protocol, researchers will survey epidemiologic factors and medical records of patients with prostate cancer in order to study the clinical characteristics of these individuals. The researchers will collect blood and tissue samples to evaluate the genetic characteristics of individuals with prostate cancer. The researchers will also collect blood samples of individuals without prostate cancer to serve as a control. The goal will be to identify genes that are associated with prostate cancer and gene profiles that are associated with differing prognoses in individuals who have prostate cancer.

Prostate cancer is a leading cause of mortality and morbidity. The purpose of this study is to develop and test non-invasive biomarkers based on methylation changes in PBMC, T-cells and circulated tumor DNA in prostate cancer patients.

The investigators' goal is to develop a non-selective and non-invasive procedure to identify aggressive tumors and simultaneously identify their exact location in Prostate cancer patients undergoing radical prostatectomy by combining multiparametric MRI and machine learning techniques. The combination of multi-parametric MRI and machine learning (validated using histopathology) can lead to increased sensitivity and specificity of cancer foci in the prostate, and help in isolating aggressive from indolent tumors. This increased sensitivity and specificity may eventually lead to: a) a reduction in the number of patients that undergo unnecessary treatment, and b) enhance current treatment options by enabling the use of focused therapies. The investigators will recruit 15 patients with prostate cancer that are currently scheduled to undergo radical prostatectomy into the study. All patients will obtain an advanced MRI study prior to the radical prostatectomy. MRI scans will include a) high-resolution volumetric images using T1 and T2-weighted imaging, b) vascular images using dynamic contrast enhanced (DCE) imaging, c) biophysical microstructure images using diffusion-weighted imaging, and d) biochemical images using MR spectroscopic imaging. Following radical prostatectomy, a pathologist will grade the prostatectomy specimens based on standard of care (Gleason grading system). Correlations will be generated between the parameters obtained from scans and from clinical assessments.

In current radiation therapy, imaging (typically, cone beam CT imaging or two orthogonal X-ray projection imaging) is done for patient setup before radiation dose delivery. Dose delivery typically takes 2 to 5 minutes depending on the delivery technique used for treatment. A tumor target may change its position during the dose delivery process. The goal of this project is develop a real-time imaging strategy to monitor the tumor position during dose delivery and evaluate its potential clinical impact.

Primary Objectives: To describe patient quality of life (QOL) related to bladder, bowel, and sexual function, as well as mental and physical health, in patients who received neoadjuvant investigational therapies prior to radical prostatectomy (RP) for high risk clinically localized prostate cancer (HRCLPC). To identify medical and demographic variables that are related with quality of life, e.g., hormonal or non-hormonal neoadjuvant treatment, time since surgery, disease recurrence, subsequent treatment, age, ethnicity, and socioeconomic status. Secondary Objectives: 1. To describe treatment satisfaction expressed by patients who have received neoadjuvant investigational therapies prior to radical prostatectomy for high risk clinically localized prostate cancer.

Retrospective Review Study for Prognostic Transcriptional Output Related to Androgen Receptor Expression in Patients Treated for High Risk Prostate Cancer with Proton Therapy

The first goal of this study is to learn more about the experience of pain and other symptoms in men being treated for advanced prostate cancer. The second goal of the study is to identify reliable ways of measuring pain which will be used in future clinical trials of treatments for advanced prostate cancer.

This study has been designed to utilize already obtained biopsy specimens for investigation of the utility of a new, non-invasive optical diagnostic technique. The study will allow a careful correlation between the Optical coherence tomography findings and conventional histology.
