Active clinical trials for "Prostatic Neoplasms"

This clinical utility study is based on a review of real but de-identified and randomized patient cases and aims to evaluate radiation oncologist's treatment recommendations before and after reviewing the results provided by the Decipher test. The primary intent is to help guide development and design of future clinical utility studies for Decipher.

This is a small study to determine if probe, similar to an ultrasound probe, can detect prostate cancer more specifically than other imaging studies in patients with a positive prostate cancer biopsy.

Patients aged 70 years or older had a higher possibility of high risk cancer than younger patients.

The objective of this multi-center prospective observational clinical study is to evaluate the clinical performance of the Carisome Prostate assay as an aid in the diagnosis of prostate cancer in men that have been scheduled for a prostate biopsy. Primarily, results of the Carisome Prostate assay will be compared with pathology results of prostate biopsy procedures. Secondarily, the performance of the Carisome Prostate test will be compared to the current standard of care for the detection of prostate cancer.

The purpose of our study is to image human prostate tissue using a transrectal photoacoustic imaging probe.

Some recent reports indicate that incidence of prostate cancer is increasing rapidly in China. However, no large-scale survey of prostate cancer has been done in central China, few data are available regarding its management. The investigators aimed to analyze the management of prostate cancer and compare the outcome of patients with such a survey. The investigators collected data of patients diagnosed with prostate cancer from the 2003 and 2008 in central China. Data were disaggregated by rural and urban hukou. The survival rate of patients was analyzed using Kaplan-Meier method. Prognostic factors were analyzed using the log-rank test and Cox proportional hazards model.

The purpose of the protocol is to describe treatment patterns among patients with prostate cancer prior to diagnosis of castration-resistant state.

The main objective of the study is to estimate and compare the overall cost of care of patients over 60 months of follow-up between two groups: (1) patients undergoing robot-assisted radical prostatectomy using the Da Vinci system versus (2) patients undergoing robot-assisted radical prostatectomy via laparotomy. The time horizon of the main objective changes to 60 months (due to the opportunity to access patient care consumption from the National Health Data System).

The purpose of this study is to set up a model for detecting micrometastases in Lymph nodes of patients with prostate cancer by quantitative polymerase chain reaction and its impact on progression-free survival.

Internal jugular vein (IJV) is the main pathway of cerebral venous drainage and it has valve system to prevent retrograde blood flow to the brain. Anatomical studies revealed that bicuspid or tricuspid valves were located in both jugular veins 2 cm above the subclavia-jugulars bifurcation and 7-18% of the valves were incompetent. IJVV incompetence (IJVVI) may result in retrograde flow which leads to brain congestion and increase of intracranial pressure, which can cause brain dysfunctions in some patients. IJVVI has been reported to be associated with transient global amnesia (TGA), cough syncope, exertional headache, transient ischemic attack, and air embolism. Demographic data are associated with the development of IJVVI. Akkawi et al. demonstrated that old age over 50 years and male gender are the risk factors for IJVVI. A few physiologic conditions are related with IJVVI including elevated intra-thoracic and intra-abdominal pressure, and pulmonary hypertension. Robot assisted laparoscopic prostatectomy (RLP) is one of the most common robotic surgery because of its significant benefits such as smaller incision, less severe postoperative pain, less intraoperative bleeding, and shorter hospital stay compared to traditional radical prostatectomy. The patients undergoing RLP are mostly over 60 years old, have neurologic, cardiac and pulmonary comorbidities. For RLP, patients are in Trendelenburg position most of the time during surgery, which could cause increases in intra-abdominal and intrathoracic pressure.
