Active clinical trials for "Prostatic Neoplasms"

The influence of Decipher test on urologist and patient treatment plan choices immediately post RP and at the time of PSA rise or BCR

The purpose of this project is to develop and evaluate fluorine-18 (F-18) fluorocholine (FCH) positron emission tomography (PET) as an imaging technique that can be used to delineate malignant tumors in the prostate gland. The proposed technique works by measuring the tissue metabolism of FCH, a substrate that is preferentially metabolized by cancer cells due to malignant over-expression of the choline transporter and choline kinase enzyme. The project scope covers a clinical study to recruit men with prostate cancer who have elected treatment by radical prostatectomy surgery. These men will undergo pre-operative PET scanning to measure F-18 FCH uptake in anatomical sextants of the prostate gland. Imaging results will be compared to histopathologic analyses of the prostatectomy specimen to determine the accuracy of F-18 FCH PET for detecting cancerous prostate sextants.

The purpose of the study is to evaluate the usefulness of 3-T magnetic resonance imaging (MRI) in the evaluation of suspected prostate cancer. Men with suspected prostate cancer based on serum prostate-specific antigen antigen (PSA) value are included. Men are randomized to pre-biopsy MRI or no MRI groups in ratio 1:1. Standard transrectal ultrasound guided biopsies will be taken in addition to extra biopsies from lesions suspicious based on MRI evaluation. Hypothesis is that more prostate cancers will be found after MRI evaluation.

Men with castrate resistant prostate cancer who are switched from a luteinizing hormone-releasing hormone (LHRH) antagonists from a LHRH agonist will experience a fall in prostate-specific antigen (PSA).

Nowadays, prostate cancer screening is largely widespread although it is not recommended yet. This screening includes primarily digital rectal examination and PSA. Recently, a new specific genetic marker of prostate cancer has been discovered. It is PCA-3 gene. The main objective is to evaluate prospectively this new marker in patients treated for prostatic pathology (benign or malign) in the department.

The primary goal for this trial is to assess the change in PET scans with the administration of zoledronate (bisphosphonate) therapy in patients with metastatic prostate cancer. It has been established that zoledronate therapy may play a role in delaying and reducing the incidence of skeletal events. Researchers propose to evaluate the change in the uptake value of FMAU PET scan after the zoledronate therapy. It has been demonstrated that FMAU PET scans can successfully demonstrate and detect bony metastatic sites in prostate cancer. In addition, investigators would like to evaluate the change in the level of the prostate-specific antigen (PSA) in the patient as well as outcome of bone scans.

This pilot clinical trial studies mechanically-manipulated ultrasound in finding tumors during robotic-assisted surgery in patients with prostate cancer. Diagnostic procedures, such as ultrasound, may help find prostate cancer and find out how far the disease has spread during surgery

Prostate cancer is the most common cancer among men in the United States. Through early detection and improved local therapies a large number of men will be cured. The clinical needs include early detection, accurate initial staging and detection of local recurrence or metastases in order to permit application of the most appropriate therapy. Therapeutic monitoring and prognostic assessment are equally important. Imaging can play an important and crucial role in meeting these clinical needs. Positron emission tomography (PET) imaging has gained an important role in the clinical management of cancer patients. 18F-DCFBC is a novel low molecular weight prostate specific membrane antigen (PSMA)-based radiopharmaceutical which is radiolabeled with a fluorine-18 positron emitter for PET imaging. Preclinical mouse prostate cancer tumor model imaging studies of 18F-DCFBC demonstrate high specific uptake in PSMA expressing prostate cancer cells. The investigators will assess the hypothesis that 18F-DCFBC, a new positron emission tomography (PET) radiopharmaceutical may possess pharmacokinetic and pharmacodynamic properties that will represent an advance in imaging prostate cancer. This initial phase I study will determine the biodistribution, pharmacokinetics, and prostate specific tumor uptake in patients with metastatic prostate cancer.

Prostate cancer is the most frequent cancer in Norwegian men. For optimal treatment, accurate staging of the disease at the time point of diagnosis is important. The objective of this study is to evaluate the diagnostic potential of a combined PET/MR examination for risk assessment and detection of lymph node metastases. The overall aim of the project is to improve the investigators ability to provide individually tailored treatment to prostate cancer patients. The study will include 32 men with high-risk prostate cancer, who are eligible for radical prostatectomy. Informed consent is a requirement for inclusion in the study.

The purpose of this study was to examine whether a cognitive-affective preparation was more beneficial, in general, and more specifically for certain subgroups, such as African-American men and individuals with high monitoring style.
