Filter by:RATIONALE: Drugs used in chemotherapy, such as paclitaxel, topotecan, and estramustine, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one chemotherapy drug may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving paclitaxel, topotecan, and estramustine together works in treating patients with metastatic hormone therapy-refractory prostate cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Intensity-modulated radiation therapy (radiation directed at the tumor more precisely than in standard radiation therapy) may reduce damage to healthy tissue near the tumor. It is not yet known whether reducing the dose of radiation to erectile tissue will help prevent erectile dysfunction. PURPOSE: This randomized phase III trial is studying intensity-modulated radiation therapy alone to see how well it works compared to intensity-modulated radiation therapy with reduced doses to erectile tissue in treating patients with stage II prostate cancer.
RATIONALE: New imaging procedures such as CT-on-rails™ may improve the ability to pinpoint the location of the tumor and decrease radiation therapy damage to healthy tissue. PURPOSE: This phase I/II trial is studying how well computed tomography (CT) scans using CT-on-rails™ work in pinpointing the location of the tumor in patients with prostate cancer.
RATIONALE: Drugs used in chemotherapy, such as docetaxel and estramustine, work in different ways to stop tumor cells from dividing so they stop growing or die. Thalidomide may stop the growth of prostate cancer by stopping blood flow to the tumor. Giving chemotherapy together with thalidomide may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving docetaxel and estramustine together with thalidomide works in treating patients with androgen-independent metastatic adenocarcinoma (cancer) of the prostate.
RATIONALE: Ibandronate may be effective in reducing bone pain caused by metastatic cancer. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known whether ibandronate is more effective than standard treatment with radiation therapy in treating metastatic bone pain. PURPOSE: This phase III randomized clinical trial is studying ibandronate to see how well it works compared to single-dose local radiation therapy in treating patients with localized metastatic bone pain.
RATIONALE: A low-fat, high-fiber diet that includes soy protein may prevent disease progression in patients with hormone-refractory prostate cancer. Nutrition counseling may help motivate patients to follow this diet. PURPOSE: Randomized phase I trial to study the effectiveness of behavior-based dietary interventions, such as receiving nutrition counseling, in helping patients who have hormone-refractory prostate cancer follow a low-fat, high-fiber, soy-supplemented diet.
This study will examine the usefulness of an imaging procedure called dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for localizing and characterizing prostate cancer. For this test, a medicine is injected into a vein and the MRI measures how the medicine flows through the prostate gland. The measurements provide information about the blood vessels in the prostate gland, which provides other information about the cancer. Several needle biopsies are performed during the procedure, and the results of the biopsies are compared with the information from the DCE-MRI. Men 18 years of age and older with suspected or confirmed prostate cancer may be eligible for this study. Candidates are screened with a medical history and physical examination, blood test, and review of tumor pathology. Participants undergo DCE-MRI and needle biopsies of the prostate. The day before and the morning of the procedure, patients are given an antibiotic called Levofloxacin. They also have a small enema the morning of the test. A local anesthetic is then given in the area around the prostate to numb the tissue and decrease any discomfort from the procedure. A tube is placed in the rectum to obtain better pictures of the prostate gland during the imaging. During the scan, the patient may be asked to breathe air that contains higher concentrations of oxygen and carbon dioxide than are in room air. The MRI scans guide the physician in selecting areas of the prostate to biopsy. For each biopsy, a needle is placed through the rectum into the prostate gland. When the needle is in place, a small tissue sample is withdrawn. This procedure is repeated until 4 to 10 biopsies are taken. During the procedure, which lasts about 1 hour, the patient lies on his stomach on a stretcher. Patients who are planning to undergo surgery or radiation treatment for their cancer at the NCI may have up to four 1-mm non-reactive gold markers placed in the prostate during the DCE-MRI procedure. The markers are left in place to help target the radiation treatments and to show where the biopsies were taken if the prostate is removed. At the end of the procedure, the patient is moved to a bed to recover and may get up and urinate after about 30 to 60 minutes. After a period of observation, the patient is discharged home with a dose of antibiotic to take the next day. Some patients may be asked to repeat the MRI and biopsy procedure during or after their treatment for prostate cancer to help investigators learn whether the MRI test is still helpful after treatment. Repeat testing is optional.
The purpose of this study is to determine the proportion of patients with a serological prostate specific antigen (PSA) by day 85.
RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and either kill them or deliver radioactive tumor-killing substances to them without harming normal cells. PURPOSE: This phase II trial is studying how well radiolabeled monoclonal antibody works in treating patients with progressive metastatic androgen-independent adenocarcinoma (cancer) of the prostate.
RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as goserelin and leuprolide may fight prostate cancer by stopping the adrenal glands from producing androgens. Drugs used in chemotherapy such as doxorubicin work in different ways to stop tumor cells from dividing so they stop growing or die. Zoledronate may prevent bone loss and stop the growth of tumor cells in bone. Radioactive substances such as strontium-89 may relieve bone pain associated with prostate cancer. It is not yet known whether hormone (androgen) ablation therapy and chemotherapy combined with zoledronate is more effective with or without strontium-89 in treating prostate cancer and bone metastases. PURPOSE: This randomized phase II trial is studying giving hormone ablation therapy, doxorubicin, and zoledronate together with strontium-89 to see how well it works compared to hormone ablation therapy, doxorubicin, and zoledronate alone in treating patients with androgen-dependent prostate cancer and bone metastases.
