Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Collecting and storing samples of tissue from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA after radiation therapy and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at changes in DNA after radiation therapy in patients with prostate cancer.

RATIONALE: Studying samples of blood in the laboratory from patients who are at high risk of developing prostate cancer may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples from patients at high risk of developing prostate cancer and from healthy male participants.

The Trans Tasman Radiation Oncology Group (TROG) has been commissioned by the Department of Health and Ageing to undertake a project to assess new Radiation Oncology Technology and Treatments. This project is being undertaken in response to a recognised need for the Medicare Benefits Schedule to support appropriate new radiation oncology technologies and treatments as they become available, to ensure optimal patient care. The first phase of the project required TROG to develop a Generic Research Framework (the Framework) capable of collecting and generating information to substantiate the safety, clinical efficacy and cost effectiveness of new technologies and treatments. The second (and current) phase of the project requires that the Framework be piloted to assess the safety, clinical efficacy and cost effectiveness of Intensity Modulated Radiation Therapy (IMRT) and Image Guided Radiation Therapy (IGRT) in four tumour site specific regions: A. Post Prostatectomy(IMRT) B. Anal Cancer (IMRT) C. Nasopharynx (IMRT) D. Intermediate Risk Prostate Cancer (IGRT) The aims of the site specific components of the ANROTAT protocol are as follows: Protocol A. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IMRT compared to 3DCRT in patients with prostate cancer (PP). Protocol B. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IMRT compared to 3DCRT in AC. Protocol C. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IMRT compared to 3DCRT in NPC. Protocol D. Develop an approach for applying the Framework to evaluate the safety, clinical efficacy and cost-effectiveness of IGRT compared to non-IGRT in patients with intermediate risk prostate cancer.

Many younger men are diagnosed with prostate cancer. These patients are often choosing radiation therapy as their primary treatment. The effect of this therapy on fertility will have a direct impact on their decision about therapeutic options and fertility preservation. The researchers hypothesize that when patients are treated with radiation for localized prostate cancer, infertility can occur due to direct damage to seminiferous tubules affecting sperm quality.

RATIONALE: Implant radiation therapy delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This clinical trial is studying the side effects and how well implant radiation therapy using radioactive iodine works in treating patients with localized prostate cancer.

The purpose of this study is to assess quality-of-life of men with prostate cancer. "Quality-of-life" means how you feel about your life as a result of your disease and its treatment. The investigators hope that this questionnaire will help show how prostate cancer treatments affect quality-of-life. It will help doctors and future patients to make better treatment choices. Some men may wish to have a more demanding treatment with a higher risk of harmful effects. Others may prefer a treatment that will have the smallest effect on their quality-of-life. This questionnaire will help us measure these effects and decide which is the best treatment for a given patient.

RATIONALE: Imaging procedures, such as PET scan, may help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying carbon-11 acetate and fludeoxyglucose F 18 PET scan of the bone in patients with metastatic prostate cancer that has spread to the bone.

This retrospective cohort study will assess the association of benign prostatic hyperplasia (BPH) treatment (5-alpha reductase inhibitors (5ARI) and alpha-blocker medications) with the occurrence of prostate cancer related mortality. This study will also assess a number of secondary endpoints including prostate cancer mortality or metastatic prostate cancer, and all cause mortality.

The purpose of this study is to describe patterns of care in CRPC patients, as well as health-related quality of life (HRQoL) outcomes associated with CRPC and its management. This study will also describe factors influencing treatment decisions including reason(s) for treatment choices and triggers for treatment changes for CRPC as well as describe clinical outcomes based on patient characteristics.

The purpose of this study is to assess the treatment patterns in participants with metastatic castration-resistant prostate cancer (mCRPC). Additionally, participant's demographic and clinical characteristics, skeletal-related events, criteria used to define CRPC, prostate specific antigen (PSA) levels and pain related to disease and overall survival will be observed.
