Active clinical trials for "Prostatic Neoplasms"

Study, for the first time in clinical conditions, the potential contribution, in terms of accuracy, of the motorised probe holder during prostate biopsies.

A UCSF PI-initiated study with a primary goal to improve decision quality, anxiety, and uncertainty, thereby increasing appropriate uptake of active surveillance and reducing over-treatment of low-risk prostate cancer. This study involves: completion of questionnaires through the secure website; consultation by a health coach to aid men with prostate cancer in making informed treatment decision (personalized coaching session(s)).

The burden of sexual dysfunction after prostate cancer surgery is responsible for the single greatest impact on patient/partner health-related quality of life; substantially more so than concern for cancer recurrence, or any other post-surgery side-effect. Consequently, there is a great need for progressive and distributable sexual health rehabilitation interventions designed to uphold intimacy and optimal sexual health. If the biomedical-psychosocial intervention is ultimately found beneficial, it will result in: 1) an empirically-based intervention that helps patients/partners maintain optimal health-related quality of life after prostate cancer surgery, and 2) a highly structured protocol and manualized intervention that is translatable to other treatment groups (e.g. radiation therapy) and University/Community-based hospitals.

There is evidence in human studies as well as animal studies that treatments to lower cholesterol can reduce the risk of dying from prostate cancer.To decide if cholesterol-lowering therapy can slow the growth of prostate cancer, the investigators would like to lower cholesterol prior to surgery and then measure the growth of prostate cancers cells when the prostate has been removed. The investigators will use the combination of two drugs that is approved by the U.S. Food and Drug Administration to lower cholesterol. The drug combination is commercially available with a doctor's prescription and sold as Vytorin®. It is known that maximal cholesterol-lower effects are seen after 2 weeks of treatment with Vytorin®. Therefore, study patients receive at least 2 weeks, but no more than 6 weeks of Vytorin® prior to surgery.

The purpose of this study is to find out if Radium-223 is effective in reducing cancer pain within 12 weeks of treatment. In order to see if Radium-223 is effective, the patient's level of pain will be followed throughout the study.

Androgen Deprivation Therapy (ADT) is standard treatment for locally advanced or advanced Prostate Cancer (PC). The musculoskeletal toxicity associated with ADT is well established, leading to a decrease in muscle mass, increased fat percentage, weight gain, sexual dysfunction and increased risk of depression, fatigue, diabetes, cardiovascular disease and reduced quality of life. Numerous studies have shown an association between physical activity, physical capacity and quality of life in cancer patients and recent epidemiological research suggest that regular, moderate-intensity physical activity may have a positive effect on survival in men with prostate cancer. Within exercise physiology there is new evidence pointing to recreational soccer as a unique form of intermittent exercise that effectively stimulates aerobic and anaerobic energy delivery systems, leading to beneficial musculoskeletal, metabolic and cardiovascular adaptations of importance for health. It is our overall hypothesis that 12 weeks of recreational soccer training 2-3 times per week will improve the health profile of PC patients receiving ADT treatment.

The Purpose of the Protein Study is to investigate whether a reduced protein diet can inhibit the growth of prostate cancer in humans. The Investigators hypothesis is that a reduced protein diet will inhibit expression of genes that are involved in the growth of prostate cancer.

In Canadian men, prostate cancer (PCa) is the most prevalent form of cancer and the third leading cause of cancer-related death. Unfortunately, PCa survivors are often burdened with feelings of anxiety and depression associated with the disease and associated treatments. Short-term exercise interventions (8-24 weeks) have improved psychosocial well-being in this population, but the impact of single bouts of exercise and related psychological or neurological changes have never been studied. The primary objective of the proposed study is to examine the effect of an acute bout of exercise on neurophysiological and psychological indicators of well-being in a randomized controlled trial (RCT) of 36 men with PCa. Participants will be randomly assigned to the intervention (60 min exercise) or control (60 min of television) and will undergo a brief neurological test (cortical silent period) and psychological questionnaires before and after their group assignment.

Men with early prostate cancer face a number of options which lie at the extremes of care. On one hand, active surveillance involves monitoring the disease and on the other, immediate treatment involves surgery or radiotherapy. The difference between these two strategies in terms of reducing the chance of a man dying from his disease is small. Not only is the benefit small, surgery or radiotherapy carry significant side-effects. These occur because of damage to surrounding tissue resulting in incontinence of urine (1 in 5), erectile dysfunction (1 in 2) and back-passage bleeding, diarrhoea or discomfort (1 in 10). The investigators have been working on new forms of treatment that use heat, light or cold to destroy tissue and minimise treatment-related harms. The investigators have not yet found one that delivers the ideal treatment. The ideal treatment is one that can be done under local anaesthetic, can effectively destroy areas of cancer, limit damage to surrounding tissues, is repeatable, and adaptable to future discoveries such as molecular targeting of cancer cells. The investigators think magnetic thermoablation may be able to deliver on these ideal attributes. Magnetic thermoablation involves injecting magnetic iron nanoparticles directly into the cancer. When a magnetic field is applied close to them, these nanoparticles heat up to very high temperatures that kill cells. Magnetic thermoablation does not use x-rays or surgical incisions. The investigators have done a lot of the preclinical work already to develop this type of treatment. The investigators now need to develop a system that can be used to treat prostate cancer. However, before the investigators can do this, they need to test whether the magnetic nanoparticles actually stay where they are injected. The consequences of them moving to areas that they should not can be serious. First, the nanoparticles could move away from the cancer which means the cancer will not be heated effectively. Second, the nanoparticles could move to sensitive structures around the prostate (back-passage, bladder, sphincter muscle controlling urine flow, nerves controlling erections). If this happens, damage of those sensitive structures could occur leading to side-effects. The investigators propose a study to try and find out what happens to those nanoparticles. The study will involve approaching men who are having their prostates removed by radical surgery. If these patients agree to participate, the investigators will inject their prostate with varying amounts of nanoparticles. The investigators will NOT heat them up. The investigators will use special scans and, once they have had their surgery, to look at the pathology specimens to see where the nanoparticles have gone. The actual nanoparticles are not harmful but the process of injection can carry a small amount of harm. If the nanoparticles stay where they are injected, the investigators will then be able to run another study in which we treat men who have prostate cancer with magnetic thermoablation.

Problem-solving therapy programs have been shown to be effective among parents of children diagnosed with cancer. Efforts have been made to apply this same strategy to spouses/significant others of men diagnosed with prostate cancer. The purpose of this study is to test the efficacy of problem-solving therapy on the spouses of prostate cancer patients.
