Filter by:There is much interest in understanding the role that vitamin D3 (cholecalciferol) plays in various cancers, and in the prognosis of various cancers once they are discovered. The purpose of this study is to examine the effects of vitamin D on prostate cancer-associated lesions and on vitamin D metabolites in prostate tissue. We will give vitamin D3 to men when they are scheduled to have their prostate removed because of cancer. The men will take vitamin D at one of 3 doses for 4-6 weeks, until the surgery is performed. We will compare the prostate tissue taken from the men receiving the higher doses of vitamin D to tissue from men assigned to the lower doses. We expect to find that the prostate removed at surgery from men who received the high-dose vitamin D treatment will appear more normal, and less cancer like. In addition, we will measure vitamin D metabolites in the prostate to confirm that these did accumulate in the prostate to bring about the effects observed.
High concentrations of anti-oxidants in pomegranate seeds present a potential strategy to delay clinical prostate cancer progression and prolong the interval from primary treatment failure to hormonal ablation. This is a 48 month extension to the double-blind GUP-0205-1 study, to compare the effects of daily consumption of pomegranate liquid extract versus placebo on the absolute prostate-specific antigen (PSA) doubling time at the end of 12, 24, 36 and 48 months in male subjects who rolled-over from the GUP-0205-1 study.
This study is an open-label extension to the double-blind GUP-0205-1 and double-blind extension GUP-0205-1XX studies. High concentrations of anti-oxidants in pomegranate seeds present a potential strategy to delay clinical prostate cancer progression and prolong the interval from treatment failure to hormonal ablation. Eligible male subjects were previously assigned to the placebo group in the double-blind core study or the double-blind extension study and were diagnosed with disease progression while on placebo treatment. Upon satisfying all entry criteria, the subjects will receive open-label pomegranate extract for up to 48 months in the absence of further disease progression or intolerable toxicity.
The goal of this clinical research study is to compare using external beam radiotherapy with intensity modulated beams for fewer days at a higher dose per day to the same type of therapy for more days at a lower dose per day in the treatment of prostate cancer. The safety of these treatments will also be studied and compared.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as triptorelin, may lessen the amount of androgens made by the body. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether giving triptorelin and radiation therapy soon after surgery or later after surgery is more effective in treating prostate cancer. PURPOSE: This randomized phase III trial is studying giving triptorelin and radiation therapy soon after surgery to see how well it works compared with giving them later after surgery in treating patients who have undergone surgery for intermediate-risk stage III or stage IV prostate cancer.
As docetaxel is proven to be effective in late stages of prostate cancer with a large tumour burden it should be effective in primarily treated intermediate and high risk prostate cancer as an adjuvant treatment after radiotherapy to prevent early relapse. This will therefore be tested in a randomised phase III trial where patients will be randomized either to docetaxel or surveillance
RATIONALE: Radical prostatectomy is surgery to remove the entire prostate. Radiation therapy uses high-energy x-rays or other types of radiation to kill tumor cells. Sometimes the tumor may not need treatment until it progresses. In this case, active surveillance may be sufficient. It is not yet known which treatment regimen is more effective for localized prostate cancer. PURPOSE: This randomized phase III trial is studying active surveillance to see how well it works compared with radical prostatectomy or radiation therapy in treating patients with localized prostate cancer.
The goal of this study is to learn more about how we measure depression in elderly cancer patients (patients aged 70 and older). Depression is one of the most common causes of emotional distress in the elderly and continues to be under-recognized. This is a problem because depression can have a negative impact on quality of life. The symptoms of depression are linked to poor health outcomes and higher costs of health care. In fact, depression is one of the top five concerns facing the elderly today.
The basic premise of this research proposal is to determine whether there is any significant association between germline polymorphisms and cancers of colon, bladder, breast, testicular, prostate, ovaries, kidney, lung, lymphoid organs, and head and neck. This is an exploratory study designed to generate hypotheses for further research.
The purpose of this study is to find out if therapy with hormones (such as Lupron, Casodex, Zolodex or Degarelix) change a person's thinking abilities.
