Active clinical trials for "Prostatic Neoplasms"

This is a cross sectional study to examine the relationship between serum calcium and PTHrP and serum PSA in men referred for prostate biopsy at Wake Forest University.

In this observational study, blood samples for pharmacokinetic (PK) testing will be collected from subjects with metastatic prostate cancer during their treatment with docetaxel. Plasma levels of docetaxel will be determined, and the subjects docetaxel exposure levels, determined as an area under the curve (AUC), will be retrospectively correlated with reports of toxicity, tumor response, quality of life, time to disease progression and overall survival to provide guidance on what the appropriate target range for docetaxel exposure should be for metastatic prostate cancer subjects receiving docetaxel therapy for their disease.

Men with and without prostate cancer will have a PET/CT scan that measures the level of the amino acid sarcosine. PET is a scanning method that uses short lived radioactivity.

To determine the feasibility and success rate of tumor tissue procurement using molecular-image-directed biopsies of responding and non-responding osseous metastases, measured by NaF PET/CT, in patients with metastatic castrate-resistant prostate cancer.

This is a randomized parallel group trial designed to evaluate the impact of implementing geriatrician-prescribed interventions based on the comprehensive geriatric assessment (CGA), on the ability to deliver adequate chemotherapy treatment, as measured by relative dose intensity (RDI).

This study is conducted to estimate population-based incidence rates of second primary malignancies among patients with CRPC similar to those treated with Xofigo. These rates will provide context for second primary malignancy incidence rates from the REASSURE study. Furthermore this study aims to provide further information about the documentation of bone metastases in Medicare data and the extent of use of only oral androgen deprivation drugs among patients with Medicare Part D coverage, as well as to estimate overall survival of the study population.

This is a study of HMB plus amino acids in older men with prostate cancer starting androgen deprivation therapy (ADT). The investigators hypothesize that the use of this nutritional supplementation will decrease the loss of muscle mass and strength that occurs when men start ADT.

The purpose of this research study is to evaluate a newer imaging technique, called 18F-Sodium Fluoride (NaF) positron emission tomography (PET). NaF is a tracer (dye) that is very sensitive for changes in bone. By using this tracer with positron emission tomography/computed tomography (PET/CT) imaging, our ability to evaluate and measure changes in bone lesions could be greatly improved.

The purpose of this study is to evaluate the Canadian Real Life Evaluation of the Effectiveness of Lupron in the Management of Prostate Cancer.

Immunological effects of radiotherapy have been described before, but not evaluated in a time-dependant manner. In order to identify a possible time frame for combination therapies, white blood cells are isolated of samples taken at different time points before during and after standard radiotherapy in patients with localised prostate cancer. The overall activity of the T-cell-system as well as tumor-specific T-cell-response are evaluated.
