Filter by:The purpose of this research is to see if MR-guided cryoablation can effectively treat prostate tumor recurrences.
Background: Prostate cancer (PCa) is the most common cancer for men. When treated early enough it is typically curable. However, common treatments, such as radical prostatectomy and radiation therapy, often result in significant negative outcomes with regard to sexual, psychological and social function. Both men and partners have identified the need for more information and support to address sexual health concerns after treatment. However, very few sexual rehabilitation interventions have been developed and rigorously assessed. Purpose: The investigators propose to develop and pilot test a new program to meet the sexual health needs of men with PCa and their partners using an online, professionally facilitated education/support program. The goals of the program are to improve sexual function, intimacy and mood for men and their partners after treatment for localized PCa. The program will be offered through Cancer Chat Canada, an existing and well-tested Canadian platform for professionally facilitated support group programs. What Participants Can Expect: A total of 24 men and their female partners (48 individuals) will be recruited and assigned to one of two groups. The first group will participate in the program immediately; the second group will be offered the program after a 5-month delay. The decision about which group will start immediately and which later will be made randomly (by chance). Both groups of men and partners will be asked to complete questionnaires three times and, at the end of the program, to provide the researchers feedback about how satisfied they were with the program, the changes they made, things they learned as a result of the program, and suggestions for improving the program. Participants must have access to a computer, an Internet connection and be willing to attend online, chat room meetings each week for 1.5 hours for 6 weeks. Implications: Sexual rehabilitation is a high need for men affected by PCa, but is difficult to access. The investigators hope to improve access to sexual health care through this study.
Prostate cancer is one of most common cancers in America, affecting 1 in 6 men. External beam radiation therapy is one of the common methods to treat prostate cancer. Although radiotherapy is effective, side effects to the adjacent normal organs limit the therapeutic ratio. Those side effects are usually associated with the radiation damage of the normal tissue surrounding prostate, e.g. bladder, urethra and rectum etc. Both effectiveness and the side effects of radiation treatment are often accessed after whole course of radiotherapy, which makes the early intervention difficult. The current research project is a feasibility study of utilizing advanced magnetic resonance imaging (MRI) techniques to access radiotherapy treatment response of prostate cancer during and right after radiotherapy. Many advanced MRI techniques, e.g. spectroscopy (MRS), diffusion-weighted (DWI), dynamic contrast enhanced (DCE) perfusion weighted images, have been used in radiology departments for diagnostic purpose. This research project is to study the feasibility of using advanced MRI sequences to monitor tissue response during and after radiotherapy. The tissue changes revealed from MRI can provide physicians early information on possible tumor recurrence and normal tissue toxicity, therefore, the early intervention may be possible to spare normal tissue and cure the patient. The project is designed to combine several different advanced MRI imaging techniques systematically to study tissue changes during radiotherapy, which has not been seen elsewhere to date. Another important goal of this research project is to study the feasibility of associating functional MRI with radiation treatment dose distribution. Tissue response during radiation treatment depends on dose. The functional MRI can provide more information than simple anatomic information. Mapping the functional MRI spatially and associating them with 3D dose distribution in radiation treatment planning system is one important step to quantitative assess the relationship between radiation treatment and tissue changes due to the radiation.
The purpose of the study is to determine whether radiotherapy improves cancer control and overall survival among patients with Castration resistant prostate cancer.
The primary safety purpose of this study is to estimate the rates of immediate and long-term high grade (grade 3-5) gastrointestinal and genitourinary side effects during the five years after TrueBeam stereotactic body radiotherapy in low-risk and intermediate-risk prostate cancer patients. The primary efficacy purpose is to compare 5 year biochemical disease free survival rates with TrueBeam to 5 year biochemical diseases free survival rates with dose-escalated external beam radiation therapy.
The purpose of this study is to look for low levels of oxygen (hypoxia) in prostate cancer using a special x-ray test called a positron emission tomography (PET)scan. Hypoxia may have an effect on how prostate cancer grows and responds to treatments like radiotherapy and chemotherapy. The use of PET scans to measure hypoxia may be better and simpler than the methods used previously.
This study examines Limited versus extended pelvic lymphadenectomy.
The aim of the randomized controlled double-blind crossover trial is to evaluate the effectiveness of two dietary supplements containing polyphenolic phytochemicals (isoflavonoid genistein and flavonoid quercetin) in comparison with placebo on the rate of increase in prostate-specific antigen (PSA). In addition, secondary objective is to evaluate the incidence of prostate cancer and to analyze malondialdehyde and protein carbonyle as indicators of the oxidative status.
Effect of Radical Prostatectomy Combined with Neoadjuvant and Adjuvant Chemotherapy in Patients with High Risk Prostate Cancer. The purpose of this study is to evaluate whether neoajuvant and adjuvant docetaxel and prednisone are effective in the treatment of high risk localized prostate cancer.
The purpose of this study is to compare the effects, good and/or bad of two treatment methods on subjects and their cancer. Proton beam radiation therapy is one of the treatments for men with prostate cancer who have localized disease. The benefit of the combination with androgen suppression is not completely understood. This study will compare the use of hypofraction proton therapy (28 treatments) alone to proton therapy with androgen suppression therapy.
