Active clinical trials for "Prostatic Neoplasms"

Interventions to Improve Shared Decision-Making: Prostate Cancer Screening is a prospective study of educational interventions to improve the interaction of physicians and their patients about prostate cancer screening. Educational material is provided in primary care practices using either standard paper information or a novel web-based interactive curriculum that explores the risks and benefits of screening measures for prostate cancer for older men. The impact of the intervention on shared decision-making with both actual and standardized patients will be assessed.

Approximately 50%-95% of prostate cancer patients undergoing radiation therapy (RT) develop symptomatic urinary problems .These symptoms can significantly diminish a patient's quality of life during and shortly after therapy. Alpha1-blockers, such as Rapaflo, act to decrease resistance to urinary flow. This multi-institutional phase III trial is designed to compare standard of care versus preventive treatment with Rapaflo for prostate cancer patients, regardless of risk group, whose treatment consists of radical radiation therapy. We plan to recruit 188 patients across Quebec who will be randomized into two arms: rapaflo prescribed at start of radiation therapy or if/when symptoms appear.

Taxotere is the current standard first-line chemotherapy for mCRPC and may be used as second-line therapy in good responders in first-line (Taxotere rechallenge). Jevtana has demonstrated a survival benefit versus mitoxantrone in patients progressing during or after Taxotere and is now the standard second-line chemotherapy. Taxotere and Jevtana have different toxicity profiles. Many patients who are receiving Jevtana for second-line treatment indicate they prefer this agent over Taxotere with regards to the general tolerance (namely peripheral neuropathy, nail changes, asthenia). This was not expected since Jevtana in post-Taxotere setting was associated with more grade 3-4 adverse events such as febrile neutropenia and diarrhea than Taxotere in first-line setting. The study design of CABA-DOC is similar to that of the PISCES trial which evaluated the patient preference between two standard treatments for first-line metastatic kidney cancer. Despite similar PFS improvements over placebo in phase III trials, results clearly showed that patients preferred pazopanib over sunitinib. A randomized phase III study is currently comparing the efficacy of Taxotere and Jevtana in first-line setting with overall survival as a primary end-point. Assessing patient preference between Jevtana and Taxotere would contribute to further identify differences between these two taxanes and clarify which one of these two taxanes should be used for second-line chemotherapy and perhaps for first-line chemotherapy in the future. Assessing patient preference between the two taxanes might be less biased in the first-line setting where patients have no previous experience with a taxane.

This study aims to test the hypothesis that insertion of an endorectal balloon into a patient receiving radical prostate radiotherapy by treatment radiographers is feasible without the patient experiencing undue discomfort. In addition this study will test the hypotheses that insertion of the rectal balloon prior to radiotherapy delivery stabilises rectal volume during radiotherapy treatment and minimises organ motion within the pelvis.

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 examine the effects of various factors such as emotions, stress, stress management techniques (for example relaxation and coping techniques), and health information on quality of life, distress, depression, coping, and physical health in men diagnosed with advanced prostate cancer. We also evaluate the effectiveness of a 10-week group-based internet delivered psychosocial intervention. Primary outcomes are symptom burden (e.g., urinary function, fatigue, pain) and HRQOL (e.g., general, physical & social functioning). Participation in this study includes three face-to-face assessments: baseline (at the beginning of the research study), 6-month follow-up, and 12-month follow-up. The 6- and 12-month follow-up interviews are conducted after the participant has completed the 10-week group intervention. Participants are randomized into either an intervention group (targets stress management skills - relaxation, coping) or a control group (health information and health promotion strategies - benefits of proper nutrition and treatment compliance). Both groups meet for 10 consecutive weeks through an internet video conferencing platform. At the baseline, 6- and 12-month follow-ups, we collect blood and saliva samples. The blood samples go through a three-day process in which we extract and store serum, plasma, and cells for further analysis and gather proliferation data. We use the saliva to measure the cortisol diurnal rhythm.

The DDI study had been designed to investigate the effect of SHR3680 on the pharmacokinetics of Repaglinide and Bupropion

Androgen deprivation therapy (ADT) is a mainstay of prostate cancer treatment to improve overall survival for intermediate- and high-risk localized disease as well as metastatic disease. While ADT improves survival, it can cause significant morbidity and a decrement in quality of life. In particular, ADT is associated with decrease in bone mineral density (BMD) and increased risk of fracture. Although current guidelines recommend continuous androgen deprivation therapy (CAD) as standard therapy for high-risk disease, there has been increasing recognition of adverse effects from CAD. Since 1986, intermittent androgen deprivation therapy (IAD) as alternative therapeutic strategy for prostate cancer has been proposed to delay development of castration resistance and to reduce the side effects of ADT. While both CAD and IAD are commonly used in real clinical practice, no prior study examined BMD change after CAD or IAD, and assessed whether bone loss would recover during off-treatment of IAD. The investigators therefore determine the rate of change in BMD induced by ADT (CAD versus IAD) in men with prostate cancer.

RATIONALE: Gathering information about patients with prostate cancer may help doctors learn more about how patients choose treatment options. PURPOSE: This study is looking at treatment choice in patients with localized prostate cancer.
