Filter by:RATIONALE: New diagnostic procedures, such as C-11 choline PET-CT scan, may be effective in finding cancer that has spread to the bone and lymph nodes in patients with prostate cancer. PURPOSE: This clinical trial is studying how well C-11 choline PET-CT scan works in finding metastases in patients with newly diagnosed high-risk prostate cancer.
The purpose of this uncontrolled, multi-center, open-label trial was to investigate the feasibility of using degarelix as intermittent androgen deprivation (IAD) therapy in the treatment of prostate cancer.
Some men complain of changes in the shape or dimensions of their penis after undergoing radical prostatectomy (removal of the prostate) for prostate cancer. Changes in penile dimensions include shortening or decreased girth. Changes in shape include a curvature or bending of the penis, and/or the appearance of indentation. These changes may be associated with formation of scar tissue involving the covering of the erection chambers, known as "plaque". The appearance of indurated plaque and a resultant curvature or indentation is a well described medical condition known as "Peyronie's Disease" and may occur in men who did or did not undergo radical prostatectomy. The purpose of this study is to evaluate these changes in penile shape and dimensions.
Studies on patterns of how many men get prostate cancer in other countries show that environment contributes to the high incidence of prostate cancer in the United States. Epidemiology studies suggest that this influence may be reduced by the diet of men at risk of getting prostate cancer. Although the exact nature of the effects of diet are not completely known, the amount of fat eaten appears to affect the number of men who get prostate cancer. The type of fat also seems to matter. Eating more of a type of fat called omega-3 polyunsaturated fat is associated with decreased prostate cancer risk. Omega-3 fat comes from fish and is quite different from the type of fat from animals and vegetables (omega-6 fat). Because the exact mechanism of this reduction in prostate cancer risk is not known, no blood test indications, called markers, have been discovered that would show the effect working. Study doctors designed this study to try to find markers in the blood tests of men who have prostate cancer, and to find out if a diet supplemented with omega-3 type fat from fish oil helps reduce those markers, hence indicating that it helps reduce the cancer in these men. These men will be compared to men with prostate cancer whose diets do not contain the fish-oil fat. The men chosen will have prostate cancer and be scheduled for operations to have their prostate glands removed. They will be chosen randomly to be given the fish-oil diet or a regular Western diet for comparison for 4 to 8 weeks. Their blood will be checked at the beginning of the diet. After the 4-to-8-week period, they will have their operations. Their blood will be checked again and a sample of their removed prostate will be examined to tell if the diet had any effect on the cancer and its markers.
The study involves use of a device called an endomicroscope to obtain high resolution images of microscopic structures during robot-assisted prostate cancer surgery. This feasibility study is largely descriptive, and will use endomicroscopy to document the cellular and architectural appearance of tissue during minimally invasive prostate surgery for later comparison with features seen upon conventional histopathological examination of biopsies or resection specimens.
The purpose of this study is to compare the location of the cancer found in the prostate gland after it is removed to the location that was predicted on the MRI scan during biopsy. In this way, we can better determine if the Magnetic Resonance Imaging (MRI) was accurate, and if the MRI could be safely used to guide other types of treatments such as brachytherapy. We also plan to carefully measure how frequently surgery is able to completely remove the cancer, as well as the side effects and effectiveness of surgery after radiotherapy. The study will be coordinated and closely integrated with a separate concurrent study of MRI-guided prostate biopsy, which will be performed prior to accrual to this trial (UHN 05-0641-C).
Prostate cancer is prevalent in the United States, with approximately 230,110 new cases and 29,900 deaths in 2004. Approximately 30% of new cases will be clinical stage T3 when they are diagnosed. This is a stage in which there is high probability that the cancer has spread beyond the prostate gland itself, making it much more difficult to treat. In these cases, when surgery is done by itself and the prostate is removed, it is still very likely that some cancer that has spread beyond the prostate remains and will get worse. Radiation applied to the prostate also does not work well on tumors that have spread beyond the prostate. Even surgery and radiation combined have not eliminated the problems caused by prostate cancer that has spread into the tissue outside the prostate itself. New treatments are needed to deal with prostate cancer at this more serious stage. Study doctors believe that it might be possible to shrink the prostate cancer using a new drug called SUO11248 or Sunitinib. After the patients take the drug, study doctors believe the cancer will shrink back to within the prostate, and they can then surgically remove the prostate and all the cancer. Patients on this study also will be given increasing doses of Sunitinib to find out how much of the drug can be given safely.
The purpose of the study is to evaluate the pharmacodynamic profile and safety of BN83495 in patients with prostate cancer with disease progression while on androgen ablative therapy
This purpose of this study is designed to compare two types of images; magnetic resonance imaging (MRI) and Trans-Rectal Ultrasound (TRUS) to see which one performs more accurately for the image-guided insertion of Fiducial Markers(FMs) within the tumour. Though effective for guiding FM placement at the poles of the prostate gland due to excellent visualization of the prostatic boundaries, TRUS may not be ideally suited for marking the GTV. Conventional TRUS is neither sufficiently sensitive nor specific for accurate visualization of intra-prostatic tumor. A new interventional MRI technique enables needle guidance to the gross tumour Volume (GTV) for FM placement. It is of particular importance that both techniques be evaluated to enable which one is more effective so that it can be implemented in the designs of future trials involving dose-escalation to prostate.
This proof-of-principle clinical trial at Mayo Clinic studies how patients and their physicians understand and utilize predictive genetic risk assessment. A critical goal of this clinical trial is to understand how individual patients and their doctors perceive and respond to genetic risk information that is largely uncertain.
