Filter by:The objectives of this study are to assess clinical practice variation in prostate cancer diagnosis and treatment among urologists and how ProMark™ affects clinical practice decision-making. The study uses a randomized controlled study design of urologists. Urologists will be randomly assigned to a control and intervention arm. - Pre-intervention/baseline assessment: will be done using prostate cancer CPV® vignettes and a physician questionnaire to both control and intervention arms. - Intervention: 2-4 weeks after baseline introduce ProMark™ to the intervention group of urologists using a protocol to be determined by Metamark and QURE. - Post-intervention: 6 weeks post-intervention, a second round of prostate cancer CPV® vignettes will be administered to both control and intervention arms. The ProMark™ test will be available to "order" for all physicians taking the vignettes. The Clinical Performance and Value Vignettes (CPV®) used in this study simulate a clinical encounter for a man presenting with prostate cancer. Each urologist will provide responses to open-ended questions regarding clinical care they would provide for that patient. These responses are scored in five domains (taking a medical history, performing a physical examination, ordering appropriate tests, making a diagnosis and prescribing treatment against explicit evidence and criteria as determined by the literature and medical associations. Results are presented as percentage correct. Each case will take approximately 15-20 minutes to complete. All case responses will be completed online and kept confidential. The study hypotheses are: 1. Clinical practice, specifically decisions around prostate cancer treatment post-diagnosis, will vary widely among urologists. This variation in practice will demonstrate the need a new diagnostic, such as ProMark™, would fulfill. 2. ProMark™ will improve clinical decision making of urologists for prostate cancer patients with a Gleason Score of 3+3=6 and 3+4=7 by improving the diagnosis and/or treatment CPV® domain score post-intervention versus baseline comparing intervention and control groups The investigators will estimate the effect of ProMark™ on the primary outcomes comparing treatment and control groups using a difference-in-difference analysis comparing differences between groups before and after intervention. The investigators will control for potential confounders, such as age, gender, and other physician and practice characteristics.
PSA (Prostate-specific antigen) testing has significantly increased the number of men diagnosed with prostate cancer (PCa) and especially patients with low and intermediate risk disease. The effect of radical treatment (treatment of the entire prostate gland) in these risk groups is disputable while the risk of adverse effects, with erectile dysfunction and urinary incontinence, is not. Active surveillance (AS) has been developed as an alternative to radical treatment with the aim of avoiding or delaying radical treatment by closely monitoring for signs of tumor progression. Active surveillance is regarded as the treatment of choice for low-risk prostate cancer. Focal therapy may have a crucial role in improving active surveillance protocols for patients with intermediate localized prostate cancer. Focal eradication of the index-tumor may delay or avoid indefinitely radical treatment for this patient group while significantly reducing treatment-related side effects. Improved MRI-diagnostics and MRI/ ultrasound fusion technology have optimized tumor mapping and classification and this in turn has made partial treatment of the prostate a feasible treatment option. This study is a prospective cohort study. Patients with intermediate (high-risk) localized PCa and a visible index tumor will be treated with high-intensity focused ultrasound (HIFU). The aim of the study is to show that there is a significant effect of focal treatment on surveillance biopsies and a reduced conversion to radical treatment, without compromising survival outcomes compared to historical controls (retrospective cohort). A cohort from the more than 450 patients included in the local AS-protocol with MRI at Vestfold hospital trust since 2009 will serve as controls.
This is a master protocol for a prospective Phase I-II study evaluating feasibility and efficacy of incorporating magnetic resonance imaging (MRI) simulation into the planning of radiation treatments.
To determine the incidence and risk factors of ethanol-induced symptoms, this multicenter, prospective, observational study is designed to include patients in Korea who are receiving chemotherapy with ethanol-containing docetaxel alone or in combination. Subjects who voluntarily provide written informed consent to provide information for this study and meet the inclusion/exclusion criteria will be given an enrollment number and will be followed during the observation period to collect study-related data in the Case Report Forms (CRFs) as predefined in the study protocol. Patients' decision to participate (or not) in this study will not affect their treatment (physician's prescriptions or diagnostic/therapeutic decisions).
This study will use polysomnography, alongside other methodologies such as questionnaires, actigraphic measurements and salivary melatonin samples used in previous studies to investigate sleep quality in patients with i) localized, locally advanced or metastatic hormone sensitive prostate cancer or ii) with full-resected early (stage I-III) epithelial breast cancer. The measurements will be taken before androgen deprivation therapy (ADT - for prostate cancer patients) or endocrine therapy (for breast cancer patients) is initiated, at 6 months and some measures again at 12 months.The groups, defined by cancer type and whether or not treatment includes ADT / endocrine therapy, will be compared to see if there are differences in the prevalence of the lowered sleep quality in the groups.
At the time of study termination, NUV-422-02 was a first-in-human, open-label, Phase 1 dose escalation study designed to evaluate the safety and efficacy of NUV-422. The study population comprised adults with recurrent or refractory high-grade gliomas (HGGs), metastatic breast cancer (mBC), with and without brain metastases, and recurrent or refractory metastatic castration-resistant prostate cancer (mCRPC). All patients self-administered NUV-422 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.
Background: Prostate cancer is one of the most common cancers in men. For some men, their cancer is monitored. Others have surgery to remove the prostate. Focal therapy is another treatment option. It treats the areas of cancer selectively, which leaves the rest of the prostate intact. This can help lessen side effects. Men who get focal therapy must be chosen carefully. The Oncotype DX Genomic Prostate Score (GPS) assay tests biopsy samples for certain cancer-related genes. It then then gives a score from 1 to 100 to predict the likelihood of poor outcomes. The GPS is used to choose men for focal therapy. Researchers want to test the GPS further. Objective: To assess how GPS may be useful when used with MRI to improve how men are chosen for focal therapy of prostate cancer. Eligibility: Men age 18 and older who had NCCN low or intermediate risk prostate cancer and had MRI and radical prostatectomy at the Urologic Oncology Branch, National Cancer Institute and collaborating centers. Design: This is a multisite study. It will review data and samples that were collected in the past. Samples and images from up to 277 participants will be used. Tumor tissue will be tested with the GPS. Data such as age at diagnosis, race, biopsy results, and pathology results will be merged with the GPS results. Data will be entered into an in-house electronic system. It will be password protected. All data will be kept in secure sites that comply with NIH security standards.
This phase I/II escalation dose study is assessing the efficacy of the recommended dose of stereotactic re-irradiation (SBRT) of relapses within the prostatectomy bed, potentiated by metformin
To perform an analysis of independent predictors of fear of cancer recurrence in patients with malignant genitourinary diseases and their impact on quality of life and survival
The majority of all new prostate cancer cases are diagnosed in men aged > 70 years, with the highest incidence in men aged > 90 years. Management options for localized prostate cancer include active surveillance in patients with low-risk disease, radical prostatectomy or external beam radiation therapy. In previous studies, hypofractionated prostate cancer irradiation regimens have been shown to represent a highly effective treatment option for prostate cancer. However, patients aged 75 years or older were underrepresented in most trials resulting in the lack of a robust evidence base. The proposed study will evaluate radiation-induced toxicity as well as outcome after hypofractionated external beam radiotherapy in prostate cancer patients aged 75 years or older.
