Filter by:Even with careful prostate surgery, men find it difficult to have an erection. Our previous research shows that couples are not often supported to cope with the effects of surgery on their sexual relationships. In this study, the investigators will design a way of supporting couples, and test how well it works. The investigators will decide what the support should include (e.g. duration, frequency and timing of the support). The investigators will do this by looking at available literature on the subject. The investigators will recruit 68 couples to the study, half will receive standard care and the other half will be invited to attend six sessions of psychosexual support with specially trained professionals (trained by men affected by prostate conditions and a cancer/couple support specialist). Before and after the support, men and their partners will be asked to complete questionnaires which measure quality-of-life, emotional needs, and their relationship. The investigators will ask the couples to fill out the questionnaires again six-months later to see if the support has long-term benefits. At the end of the study the investigators will also interview 10 couples to find out their views of the support, and another 10 couples about standard treatment. When the investigators have tested this support, they expect to see men and their partners tell us that their quality of life has improved, and they have higher satisfaction with their relationship. The investigators will calculate the overall cost of providing this support, and the benefits it has on reducing the need for other health-care services (like GP use).
Multi-centre Randomized Clinical Trial: 106 patients with confirmed unilateral high-volume low risk (Gleason score 3 + 3) or intermediate risk prostate cancer (Gleason score 3 + 4) will undergo an IRE treatment. These patients will be randomized into one of the two groups of the study. Group 1: Focal ablation of the prostate at the side of the positive biopsies (focal-ablation) Group 2: Extended ablation of the prostate (extended ablation) Patients will have an ultrasound of the prostate and the imaging data will be entered into the Planning Software system of the IRE-device. The volume of the prostate is measured and a specified ablation zone will be determined. The patients will be admitted for overnight stay in the hospital on the morning of the scheduled IRE procedure. The IRE will be performed under general anaesthetic and the specified zone identified in the planning stage will be ablated. Two to four IRE electrode needles will be placed into the prostate under ultrasound image guidance with a perineal approach using a brachytherapy grid. When the needles are in place, electric pulses of one to two minutes duration are used to ablate the specified zone. The total procedure time will be approximately 1 hour. Safety data will be collected and patients will be followed up at 1 day post-operatively, 1 month, 3 months, 6 months and 1, 2 and 3 year(s) post IRE.
This project will develop and evaluate a treatment plan for prostate focal therapy based on low dose rate brachytherapy. The participants entering this study are those suitable for active surveillance. These participants will be monitored with various imaging methods and interventions such as MR elastography, Transrectal ultrasound elastography, PET/CT and transperineal mapping biopsy to determine the extent of cancer and suitable treatments. Those suitable for focal therapy will be offered the option of low dose rate brachytherapy (LDRB) focal therapy in addition to active surveillance or radical therapy. This study will be used to evaluate the long term use of multi-modal, multi-parametric prostate cancer imaging, combining data from MRI, ultrasound and 11C-choline PET/CT. Such methods can be used to eliminate the need for invasive methods such as mapping biopsies.
This Phase I/Ib trial is studying the absorption and metabolism of phytochemicals found in black raspberries in men undergoing surgery for prostate cancer. This knowledge will help us design future chemoprevention studies and assist in making future dietary recommendations for men at high risk for prostate cancer.
The purpose of this study is to compare overall survival in newly diagnosed metastatic prostate cancer patients randomly assigned to androgen deprivation therapy (ADT) + TAK-700 versus ADT + bicalutamide.
There is now substantial evidence that B cells are recruited into prostate cancers by CXCL13 released by the tumor cells. B cells release lymphotoxin which drives malignant cell proliferation through the NFkB pathway. This is a pilot trial in 18 patients to determine whether depletion of B cells by rituximab will result in a decrease in the extent of B cell infiltration of the prostatic cancer. The extent of infiltration in the diagnostic biopsy will be compared to that in the prostatectomy samples following administration of 4 weekly doses of rituximab.
This randomized phase II trial studies how well a controlled low calorie diet works in reducing side effects and increasing response to chemotherapy in patients with breast or prostate cancer. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Eating a special diet with low calories may reduce the side effects of chemotherapy and improve the response to treatment
Prostate cancer is common in males and may develop over the course of an individual's life. This cancer is often discovered at the time of routine physical examinations and/or blood work or on rectal examination. Once diagnosed, most patients do require some form of treatment so that the prostate cancer does not progress to cause damage and/or shortened lifespan. Occasionally, after patients receive treatment, the investigators have found that an area of cancer remains within the prostate. Those patients with a large area of cancer (i.e. seen on MRI image) appear to have a higher chance of remaining or recurrent prostate cancer even after standard treatment. Thus, the investigators believe that the area of the prostate gland occupied by a dense area of cancer may need more radiation therapy than normal to remain cancer free. Standard therapy currently in place in North America: Currently patients who are diagnosed with prostate cancer have 3 common options: surgery, external beam radiation therapy (EBRT) alone or internal radiation (brachytherapy). Patients may or may not receive hormone therapy alongside the radiation depending on their physician's preference. For those who receive radiation therapy, the tumor typically receives the same dose as the rest of the prostate gland. Findings to date: In the past few years the investigators have discovered that patients with a tumor large enough to be seen on MRI images (>5mm) have a higher chance than normal of having cancer remain in the prostate, despite receiving treatment for their cancer 3 years earlier. Using new technology investigators can deliver radiation therapy after viewing the prostate tumor on MRI. This guides therapy, allowing the radiation treatment to be targeted to the tumor within the prostate. Based on this earlier success the investigators believe that they can now safely give a higher dose of radiation to specifically target the cancer within the prostate gland. Reason for the study: The investigators would like to test this technology and expertise to give radiation to a higher than normal dose to the tumor nodule in prostate gland.
The dominating problem after local radiotherapy of prostate cancer is rectal toxicity. If the rectum could be completely moved out of the treated volume, a substantial decrease of rectal toxicity seems reasonable. In this study we will develop and evaluate a new transrectal injection technique where hyaluronic acid (HA) is injected in the space between the prostate and the rectum prior to external beam radiotherapy to increase the physical distance between prostate and rectum.
This phase II trial studies how well finite androgen ablation with or without abiraterone acetate and prednisone work in treating patients with prostate cancer that has come back. Androgen can cause the growth of prostate cancer cells. Hormone therapy, such as finite androgen ablation, using leuprolide acetate, goserelin acetate, degarelix, bicalutamide, flutamide, and nilutamide may fight prostate cancer by lowering the amount of androgen the body makes. Abiraterone acetate may help to decrease the production of testosterone, and prednisone may help lower or prevent some side effects. It is not yet known whether giving acetate, goserelin acetate, degarelix, bicalutamide, flutamide, and nilutamide with or without abiraterone acetate and prednisone may work better in treating patients with prostate cancer.
