Filter by:This is a study of men who have undergone a standard 10 or more core biopsy for detection of prostate cancer and determined to have prostate cancer Gleason score ≤ 7 (low to moderate risk 2-7). Of these men, one arm of a two arm randomized group will be administered a treatment regime of Dutasteride versus the control group who receive standard of care, prior to mapping biopsy. This proposal aims at studying the apparent effect of the use of Dutasteride (3 months) on initial tumor volume (at diagnosis) in men with low volume cancer before undergoing 3D mapping biopsy.
RATIONALE: Studying samples of blood and urine from patients with cancer in the laboratory may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at a biomarker, 11-dh-TXB2, in blood and urine samples from patients with prostate cancer and healthy volunteers.
The purpose of this study is to examine whether psychoeducation counseling for older cancer patients undergoing treatment is feasible and worthwhile. The investigators will test this in a group or individual phone counseling format. Many cancer patients seek counseling to help with the emotional burden of their illnesses. Counseling often helps them cope with cancer by giving them a place to express their feelings. This geriatric-specific psychoeducation is intended to help older cancer patients cope with the burden of cancer and aging. The purpose of this study is to see if this type of counseling helps reduce depressive symptoms, anxiety, perception of loneliness and isolation. In addition this counseling aims to improve coping and quality of life (QOL). Individuals who choose not to take part in the intervention study will be asked if they are willing to participate in a brief refusal sub study. The purpose of the refusal substudy is to compare levels of distress in patients that choose to participate and those that decline. This will yield valuable data that will help us distinguish between patients that decline due to lack of interest in research and those that decline due to high levels of distress. Participation in the refusal sub study consists of completion of 2 brief questionnaires.
This study will compare a newly-developed patient education program to help men with localized prostate cancer manage treatment-related side-effects versus usual care. The new intervention will be developed for men with lower health literacy. That means that the education materials will be developed for sixth grade reading level or lower. The materials will include lots of examples and illustrations to make it easier for people understand the information.
The Acute Pain Service (APS) at Sunnybrook has been using Gabapentin 200 mg three times a day (TID) resulting in anecdotal benefits in terms of analgesia and opioid sparing effects. Higher doses of Gabapentin were associated with an increased incidence of sedation. The purpose of the study is to investigate if Gabapentin 200 mg given three times a day for 72 hours (9doses) results in a reduction in the total amount of opioid required after radical prostatectomy surgery as compared to placebo, and if analgesia is improved. This study will also examine the possible anxiety sparing effects and any health related quality of life (HRQL) changes, which may be a result of our perioperative use of gabapentin.
Patient anatomy and position during the course of radiation therapy can vary from those used for treatment planning; a function of patient movement, uncertainty in positioning system, and organ motion. Traditionally, treatment margins are designed to compensate for interfraction prostate setup variability. This approach has the potential to lower the overall effectiveness of treatment because the prostate gland is a continuously moving target whose motion cannot be accurately accounted for solely on the basis of interfraction movement. More recently, the dosimetric relevance of intra-fraction prostate motion has been recognized, and may be compensated for by continuous real-time adaptive radiation therapy afforded by the Calypso 4D Localization Systemâ„¢. In the current study, the investigators propose to characterize intrafraction prostate motion. The investigators hypothesize that intrafraction prostate motion is correlated with respiratory motion.
The proposed project is aimed to build a Duke University-specific longitudinal urologic surgery database. It will be used as the main resource to support future research within Urology and Duke University.
RATIONALE: Selenium supplements may stop or delay the development of prostate cancer in patients at high risk of prostate cancer. It is not yet known which dose of selenium may be more effective in preventing prostate cancer. PURPOSE: This randomized phase III trial is studying how well selenium works in preventing prostate cancer.
The purpose of this study is to determine, in both low-risk and intermediate-risk cohorts, the rates of acute and late grade 3 or higher gastrointestinal and genitourinary toxicity observed during a 24 month follow up and to estimate the rate of biochemical Disease-Free Survival, Phoenix and American Society for Therapeutic Radiology and Oncology definitions, at 2 years following hypofractionated stereotactic body radiation therapy for low and intermediate risk prostate cancer.
This trial studies the side effects and best way to perform genetic testing in predicting biomarkers of recurrence in patients with prostate cancer undergoing surgery. Collecting and storing samples of tissue, blood, and other body fluids from patients to test in the laboratory and collecting information about the patient's health and treatment may help doctors learn more about cancer and help predict the recurrence of prostate cancer
