Filter by:RATIONALE: Soy protein/isoflavones and venlafaxine may help relieve hot flashes in patients receiving hormone therapy for prostate cancer. It is not yet known whether soy protein/isoflavones are more effective than venlafaxine when given together or with a placebo in treating hot flashes. PURPOSE: This randomized phase III trial is studying soy protein/isoflavones and venlafaxine to compare how well they work when given together or with a placebo in treating hot flashes in patients receiving hormone therapy for prostate cancer.
The "Agricultural Health Study" (AHS) is a collaborative effort between the National Cancer Institute and the National Institute of Environmental Health Sciences. The U.S. Environmental Protection Agency and the National Institute for Occupational Safety and Health are providing support for a limited exposure assessment effort. Initial data collection on a prospective cohort of 89,658 study subjects has been completed as of December 1997. Participants completed questionnaires that included items on pesticides used, other agricultural exposures, and work practices that modify exposure as well as on other activities that may affect either exposure or disease risks (e.g., diet, exercise, alcohol consumption, medical conditions, family history of cancer, other occupations and smoking history). Phase II of the study (1998-2003) updated information on occupational exposures, diet, work practices and medical history by means of a computer assisted telephone interview. We also collected buccal cells on sample of 34,000 study participants to assess the effect of inheritable polymorphisms and the interaction of environment and genomic predisposition. The stimulus for this prospective investigation comes from the growing evidence that, despite a low mortality overall, farmers experience an excess of several cancers. These excesses have been observed in retrospective epidemiological studies among agricultural workers in several countries. Excess cancers are observed for the lymphatic and hematopoietic system, connective tissue, skin, brain, prostate, stomach and lips. Several of these tumors (brain, NHL, multiple myeloma, and prostate) are also increasing in the general population in many of these countries. This suggests a common set of exposures may explain the high rates in farmers and rising rates in the general population. Farmers, their families, and other pest control workers may have contact with a variety of potentially hazardous substances including pesticides, solvents, fuels and oils, engine exhaust, dust and zoonotic viruses and other microbes. Our cohort study includes all registered pesticide applicators in Iowa and North Carolina and the spouse of applicators who are farmers. The health effects of pesticide use are the primary focus of the study. The influence of other farm exposures are also being evaluated. The focus of the phase II follow-up period (2004-2008) is to update exposure information and health histories by means of a computer assisted interview and also following the cohort to determine disease incidence and mortality. The cohort is being followed through the cancer registries within Iowa and North Carolina, the Social Security Administration database, state vital statistics offices, National Death Index, and various in-state databases, such as the listing of registered pesticide applicators. Individuals who enrolled into the study but who are no longer at the address given during enrollment (based on subsequent attempts at follow up) have been submitted and will continue to be submitted (through NIOSH) in the standard format to the IRS under their Project 057 Taxpayer Address Request Program. Identifying data provided to the IRS include only SSN and the first four letters of last name of cohort member. IRS provides in return the most current address in IRS records if a match (SSN + all four letter of last name) is found. The purpose of this effort is to identify members of the cohort who have moved out of state, to enable adjustment of person-years for incidence and mortality calculations. Persons who have moved out of state can be followed for vital status and cause of death, but not for cancer incidence. Continuation of the protocol will provide a valuable epidemiologic resource to help prevent cancers in the future by identifying risk factors in the rural/agricultural environment. Because more cases of important cancer outcomes occur in this cohort every year, potential cancer causes can be evaluated with increased statistical power. Larger number of cases also allows for statistical control of confounding factors, making more meaningful conclusions about cancer risk, and, for some relatively infrequent cancers, such as the lyphomas and leukemias, greater follow-up time is necessary to make any meaningful observations.
The purpose of this study is to evaluate whether treatment with a new drug called ZK-Epothilone (ZK-Epo) given with prednisone in patients with androgen-independent prostate cancer, who have not had previous chemotherapy, is safe and helps to decrease PSA (Prostate-specific antigen) levels.
The purpose of this study is to determine the acute and late toxicities from radiation therapy in combination with bevacizumab (given every 2 weeks for 16 weeks then every 3 weeks for 12 weeks), bicalutamide (every day for 16 weeks) and goserelin (every 3 months for 2 years).
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Androgens can cause the growth of prostate cancer cells. Drugs, such as goserelin and bicalutamide, may stop the adrenal glands from making androgens. Radiation therapy uses high-energy x-rays to kill tumor cells. Bevacizumab may also make tumor cells more sensitive to radiation therapy. Giving bevacizumab together with hormone therapy and radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bevacizumab together with hormone therapy and radiation therapy works in treating patients with high-risk locally advanced prostate cancer.
RATIONALE: Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Docetaxel may make tumor cells more sensitive to radiation therapy. Giving docetaxel together with radiation therapy and prednisone after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying how well giving docetaxel together with radiation therapy and prednisone works in treating patients who have undergone surgery for prostate cancer.
The primary objectives of the study are: - To evaluate feasibility, safety and tolerance of 6 months administration of Revlimid at 5mg/day and 25mg/day, given orally in subjects with prostate cancer with evidence of biochemical relapse (M0) following local treatment (i.e., surgery or radiation). - To assess the rate of PSA (prostatic specific antigen) progression at 6 months after treatment with 5mg/day and 25mg/day of Revlimid (CC-5013) in patients with evidence of biochemical relapse after local therapy. The secondary objectives of the study are: - To provide preliminary assessments on the effects of Revlimid (CC-5013) at 5mg/day and 25mg/day on various PSA constructs in the subject population (i.e., PSADT [Prostatic Specific Antigen Doubling Time] and PSA slope) by comparing pre and post treatment patterns in each arm. - To evaluate preliminary pharmacodynamic correlations between serum revlimid concentrations and toxicity, PSA constructs and other evidence of disease progression.
The size of the prostate changes due to insertion of the radioactive seeds. We will measure the prostate size, before and after the procedure.
RATIONALE: Dietary supplementation with soy may keep prostate cancer from growing in patients planning to undergo surgery. PURPOSE: This randomized phase II trial is studying a soy supplement to see how well it works compared to a placebo in treating patients undergoing surgery for localized prostate cancer.
The purpose of this study is to assess the safety and activity of DC/PC3, a dendritic cell vaccine used as immunotherapy for prostate cancer. The vaccine is made with each participants' own immune cells obtained through blood donation. Dendritic cells are known to activate other immune cells such as T cells, that are able to mount an attack against cancer cells. The dendritic cell vaccine will be administered as injections every 2 weeks over a course of 2 months.
