Filter by:This is a prospective phase II trial of docetaxel-samarium in patients with hormone-refractory advanced prostate cancer who achieve a response or a stabilization to docetaxel-estramustine.
BACKGROUND: -This study represents a progression from findings in four previous National Cancer Institute (NCI) Radiation Oncology Branch (ROB) protocols (02-C-0167A, 02-C-0207E, 03-C-0190B, 04-C-0171). In these previous works we have begun to develop techniques to obtain magnetic resonance (MR) biological images and co-register tissue in prostate cancer patients. OBJECTIVES: -The scientific objective of this protocol is to determine the maximum tolerated dose (MTD) of external beam radiation to regions of interest within the prostate based acute toxicity. Secondary objectives of this study are to relate patterns in gene and protein expression to response and toxicity and to evaluate the frequency of late term toxicity. ELIGIBILITY: -Patients with prostate cancer without evidence of metastasis will be eligible for this study. DESIGN: - This phase I trial will use intensity modulated radiation therapy (IMRT) to deliver escalating doses of external beam radiation to regions of histologically confirmed prostate cancer. The study will be conducted using a standard 3-6 dose-escalation with an initial 3 patients in each dose cohort and the potential expansion of the cohort to 6 patients. - Anatomic magnetic resonance imaging (MRI) and magnetic resonance (MR) biological images, such as magnetic resonance spectroscopy (MRS), will be obtained. Tissue will be acquired from sites of interest, with biopsy locations precisely translated (co-registered) to an MR image of reference. Tissue samples will be processed for complementary deoxyribonucleic acid (cDNA) microarray testing and stored for future analysis in the Radiation Oncology Branch, NCI. A gold seed will be left at the biopsy site as a fiducial marker to direct future radiation therapy. If necessary, additional fiducial markers will be placed for target localization during treatment. - Once MR guided biopsies are obtained and fiducial markers placed, the patient will undergo a standard computed tomography (CT) simulation for radiation therapy treatment planning. The MR and CT images will be fused. Areas of pathologically confirmed malignancy will undergo dose escalation as described below. Areas of image abnormality that could not be biopsied or were without definite pathologic evidence of malignancy will be given intermediate doses. The remainder of the prostate gland will receive standard dose (7560 centigray (cGy)`). - The trial will accrue 18 to 36 patients with an anticipated accrual period of 2 years.
Prostate cancer is the most common malignancy in males, and radiotherapy is a commonly chosen treatment option for patients with localized disease. Technical innovations such as three-dimensional conformal radiotherapy (3D CRT) and intensity-modulated radiotherapy permit radiation dose escalation and possibly better disease outcomes, but escalated doses may be accompanied by long-term complications. This study will examine, for the first time, the independent contribution of a patient's own genetic makeup to the development of post-radiation complications, permitting the future development of predictive tests to avoid radiation injury. To do this, the investigators will examine gene markers and blood proteins in a series of approximately 100 prostate cancer survivors who have received three-dimensional conformal radiotherapy between 1996 and 2000 at the Cross Cancer Institute.
The clinical outcome after external beam irradiation for prostate cancer is disappointing in the advanced tumor stages. There are indications that an increase in radiation dose to the tumor will improve outcome significantly, especially to the biologically active tumour parts within the cancer area. Until recently no imaging equipment was available to define both the anatomic and biologically active tumor parts. Now, at the Center for Biological Imaging and Adaptive Radiotherapy, equipment is at hand that will be able to visualise the areas mentioned above. When combining the data of these imaging modalities it might be possible to create an optimised irradiation plan. This study is a planning study in which, on 15 patients, the different anatomical and biological imaging data per patient will be evaluated, matched and finally a theoretical improved irradiation treatment plan will be made. This research complies with the current opinion on radiation development. Progress in functional imaging is likely to provide the tools required for individualised risk-adapted radiotherapy.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of calcitriol may prevent prostate cancer. It is not yet known whether calcitriol is more effective than observation in preventing prostate cancer. PURPOSE: This randomized phase II trial is studying how well calcitriol works in preventing prostate cancer in patients with prostatic intraepithelial neoplasia.
Participants responding well in Study FE200486 CS06 (NCT00117949) were given the opportunity to continue treatment with degarelix under a clinical study until FE200486 was available on the market or until the study was discontinued. Study FE200486 CS06A was to provide knowledge of the long-term safety and tolerability of FE200486.
The purpose of this trial is to study KOS-862 in men with metastatic prostate cancer who have failed a docetaxel-containing regimen.
V-0039 is a Phase 1/2 dose escalation trial of CG7870 in combination with Docetaxel in metastatic hormone-refractory patients who have not received chemotherapy. All patients will receive docetaxel. In the dose escalation phase of the study, patients will receive treatment intravenously with CG7870 at one of up to four dose levels. In the Phase 2 portion of this study, additional patients will be added at the maximum tolerated dose that is determined in Phase 1.
RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Androgens can cause the growth of prostate cancer cells. Drugs, such as goserelin, leuprolide, flutamide, or bicalutamide, may stop the adrenal glands from making androgens. Giving bortezomib with hormone therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bortezomib with or without hormone therapy works in treating patients with relapsed prostate cancer.
RATIONALE: Drugs used in chemotherapy, such as epirubicin and docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of epirubicin when given with docetaxel in treating patients with metastatic prostate cancer.
