Filter by:The purpose of this study is to conduct a 12-month randomized controlled trial comparing the effects of strength and impact exercise training to flexibility/relaxation training on body composition (bone, muscle and fat mass), physical function (strength, gait, power, balance and self-report physical function and symptoms) in men currently treated with hormone therapy for prostate cancer.
The target volume in prostate cancer radiotherapy typically consists of the entire prostate gland which is localized by contours drawn on axial computed tomography (CT) radiation planning images. Compared with CT, magnetic resonance (MR) can provide better definition of the prostate gland with respect to the surrounding tissues and the use of multi-plannar reconstruction avoids the problem of partial volume averaging inherent in CT. CT has been shown to significantly overestimate the volume of the gland using the MR-defined prostate volume as the gold standard. Co-registration of MR and CT datasets, matched on fixed bony landmarks, has enabled radiation planning using a MR-defined clinical target volumes, combined with CT-based electron density information necessary for radiation treatment planning. Rationale and Hypothesis: Co-registration may allow better delineation of tumour volumes in prostate cancer. This investigation is a fesibility study designed to evaluate and optimize imaging parameters and co-registration techniques for CT planning and MRI Simulator.
Radical prostatectomy and radical radiation therapy remain the standard treatment approaches for patients with clinically localized prostate cancer (T1, T2).Radical prostatectomy is most effective when the disease is organ confined at the time of surgery. However, in many series up to 60% of patients have positive resection margins at the time of surgery and there is evidence to suggest that these patients may not be curable by surgery alone. A number of preoperative clinical variables including clinical stage, serum Prostate Specific Antigen (PSA) and Gleason scorea re helpful in determining the probability of finding organ confined disease at the time of syrgery.
The purpose of this study is to determine the most appropriate radiation implant dose for palladium-103 monotherapy. Radiation dose is related to potential cure. From previously published studies, it appears that the prescribed radiation dose can be reduced by 14-20% without any difference in potential cure (in this study, the dose is being decreased 10%). Although most patients tolerate brachytherapy well, complications to appear to be related to radiation exposure to normal structures (i.e. urethra, rectum and proximal penis). By reducing the prescribed dose, it is conceivable that fewer patients will experience side effects and complications.
To evaluate the efficacy of SR31747 given at 75 or 125mg per day versus placebo in androgen prostate cancer patient without distant metastases with Time to Clinical progression as main objective and PSA parameters, Tumor response, survival , safety,Tumor-related symptoms deterioration Quality of Life, PK analysis as secondary objectives
The purpose of this study is to establish the correct scanning parameters for obtaining good quality 3 Tesla (3T) magnetic resonance spectroscopy images (MRSI) of the prostate gland before and after brachytherapy implantation for prostate cancer. Three Tesla MRSI may be a valuable additional diagnostic and follow-up investigation for prostate cancer patients.
This is a phase II study designed to evaluate the potential clinical efficacy of thalidomide in patients with hormone-refractory prostate cancer. An important aspect of this study is to characterize the pharmacokinetics of thalidomide, as well as make correlations between the degree of angiogenesis occurring in a patient and the activity of thalidomide.
This is a dosage escalation study to estimate the maximum tolerated dose of staurosporine analogue UCN-01. Groups of 3 to 6 patients receive a 72-hours intravenous continuous infusions of UCN-01 from day 1 to day 4 of each cycle the first cycle only, and over 36-hours on subsequent cycles. The side effects are allowed to disappear for up to 28 days. This cycle is repeated after evaluations and follow-ups, which are every 4 weeks, as long as the patient benefits.
One current hypothesis as to what limits duration of initial hormone response is the rapid emergence of hormone resistant prostate carcinoma cells. Suramin has shown effectiveness as a treatment for hormonally refractory prostate carcinoma. Survival was less in patients with high rather than low circulating androgen levels. Thus, suramin might slow the emergence of hormone refractory tumor cells while combined androgen ablation may maximize the effectiveness of suramin. In this trial, we will pilot this concept.
