Filter by:Prostate cancer is the most commonly diagnosed cancer among males in the U.S. More than 220,000 men will be diagnosed with prostate cancer in the USA this year and more that 31,000 will die of this disease. Androgen deprivation, the elimination of testosterone and its active metabolites, remains the single most effective intervention available for the treatment of advanced prostate carcinoma. Androgen deprivation induces an immune response to normal prostate and prostate cancer, which is usually short-lived. Estradiol induces activation of many arms of the immune system and may be a more effective and long lasting means of inducing immunity to prostate tissue. This study will treat clinically localized prostate cancer patients with either estrogens, or standard androgen deprivation without estrogens, prior to prostatectomy in order more completely to describe immune regulation by estradiol in men. Control tissue from patients who have not been treated with androgen deprivation will be procured from the Northwest Special Projects in Oncology Research Excellence (SPORE) tissue core and used as comparisons against the cancers treated before prostatectomy. Tumors removed at prostatectomy, tissue samples and blood samples will be assessed for immune system changes.
The present study will provide information on whether the somatostatin analog, octreotide acetate, could have an inhibitory effect on circulating chromogranin A. The demonstration of an antisecretory effect of somatostatin analogs could offer a rationale for a large scale randomized study.
This trial will compare no treatment to exisulind therapy. Patients enrolled on the treatment arm will begin treatment 4 weeks prior to the scheduled date of surgical removal of the prostate and will take 375 mg by mouth daily for the 4 weeks prior to radical prostatectomy. Participants will be followed for total of 2 months from the time of starting study drug.
This is a study in which patients with prostate cancer treated by surgical removal of the prostate and considered to be at risk for prostate cancer recurrence will receive Exisulind 250 mg twice a day or placebo twice a day for two years.
The purpose of this study is to see if the combination of chemotherapy drugs and drugs to suppress testosterone (hormone therapy) is effective in controlling early prostate cancer. This study will attempt to: - stop or slow the growth of disease - gain information about prostate cancer - evaluate the effectiveness and side effects of the study drug
The purpose of this study is to target lesions of the prostate in the bone and to biopsy these lesions using MRI to identify the areas.
The study populations consist of a sample of the patient population (men aged 40-79 years) of a large, group model HMO and a community sample of men age 50-79. Follow-up interviews of men randomly assigned to the intervention and control groups are being conducted by telephone to assess issues related to prostate cancer screening and the men’s use of the CD-Rom educational intervention.
When we acquired MR images of the prostate gland using a coil (receiver antenna) inside the rectum, we can see areas with tumour in the prostate gland, and well as details of the anatomy. The coil inside the rectum changes the shape of the prostate gland. In order to use this images to help target radiation therapy to the tumour better, we need to deform the images to the original shape of the prostate gland without the coil. In this study, we will develop a way to deform the images accurately.
This study is designed to determine whether the combination of low dose cisplatin and strontium-89 shows clinical promise for the symptomatic treatment of bone metastases in hormone refractory prostate cancer.
Swelling of the prostate can occur during and after a brachytherapy. This swelling can cause urinary problems ranging from difficulty voiding to urinary retention. The purpose of this study is to investigate whether Mobicox started one week before brachytherapy and then continued afterwards is more effective in reducing the risk of needing a catheter than Mobicox given only afterwards.
