Filter by:The purpose of this study is to establish a more accurate and precise way to image (take pictures of) metastatic bone disease in patients with prostate cancer for staging and monitoring response to therapy. More specifically, the study aims to evaluate the capabilities of dual energy CT as a more precise and accurate tool for staging and monitoring of therapy response in patients with osseous metastases from castrate-resistant prostate cancer. Bone metastases in prostate cancer patients are a clinical and diagnostic challenge to image. Sometimes very small metastatic bone lesions may only become detectable by imaging in response to therapy due to increased bone deposition during the first three months after therapy. Commonly used imaging tests (such as regular CT or bone scan) are unable to reliably tell the difference between increased bone deposition (therapy response) and growth of the lesion (progressive disease). This diagnostic challenge may have profound negative effects on patient management since it may require additional imaging before an accurate determination of tumor response can be made. An appropriate determination of tumor response is needed for appropriate management of prostate cancer. The investigators anticipate that the new imaging tested in this study (called dual energy CT) may provide additional critical information in this clinical and diagnostic challenge. Approximately 100 people with prostate cancer and metastatic bone disease will take part in this study. At enrollment, three months, and six months, they will will receive a non-enhanced (without contrast) dual energy CT scan of the chest, abdomen and pelvis before receiving their routine, clinical contrast-enhanced CT scan.
Monocentric study. Objective : Determination of the repeatability of fluorocholine PET/CT in prostate cancer
To demonstrate the acceptability and feasibility of recruitment to a randomised chemoprevention study of standard (300mg) or low dose (100mg) aspirin vs. placebo and/or Vitamin D3 vs. placebo in patients enrolled on an Active Surveillance programme for prostate cancer.
Rationale: The current limitations in prostate cancer diagnostics, due to lack of accuracy of the available techniques, lead to over- and undertreatment for a significant fraction of patients with prostate cancer. Multiparametric ultrasound (mpUS), a new imaging modality combining different ultrasound parameters, heralds the potential for an accurate imaging-based diagnostic approach accessible to the community at large but formal validation of mpUS against final pathology results are still lacking. Objective: To validate mpUS as imaging modality for detection and localization of prostate cancer by direct correlation with histopathology of radical prostatectomy specimens
AIM: The aim of the present study is to investigate if Internet-delivered Mindfulness-Based Cognitive Therapy (I-MBCT) can reduce symptoms of depression and anxiety among women treated for breast cancer and men treated for prostate cancer compared to a treatment as usual control group. Furthermore, the effect of I-MBCT on symptoms of stress, insomnia, quality of life, and self-compassion and the potential mediating effect of working alliance and mindfulness will be explored. Finally, the cost-effectiveness of the I-MBCT intervention will be explored. BACKGROUND: Symptoms of depression, anxiety, and stress are prevalent late-effects among cancer patients and -survivors. Mindfulness-based interventions aim at improving affect tolerance and emotion regulation, which could be of particular relevance for cancer patients and survivors, and MBCT has been shown efficacious in treating symptoms of depression, anxiety, and stress among cancer patients and survivors. However, the availability of face-to-face delivered MBCT is limited and hence using the internet to deliver MBCT may be a cost-effective way of increasing the accessibility of the intervention to vulnerable patients with limited resources. METHODS: A total of 155 participants will be recruited from Department of Oncology and Department of Urology at Aarhus University Hospital and randomized to two groups: I-MBCT and a treatment-as-usual wait-list control group. Assessments will be conducted at pre-, midway and post intervention and at a 6- months follow-up.
The primary goal is to prospectively estimate the median PFS of African American and Caucasian men with mCRPC taking apalutamide, abiraterone acetate, and prednisone. Secondary objectives include: PSA kinetics: to determine the duration of PSA response, time to nadir, and percent of men who achieve a PSA < 0.1; Radiographic assessments: to estimate the rate of objective response and incidence of bone flares; Safety (NCI CTC v4.0) and tolerability, particularly incidence and grade of hypertension in the two populations. This is a non-comparative pilot open-label, parallel arm, multicenter study of apalutamide and abiraterone acetate in African American and Caucasian men with mCRPC. It is anticipated that 3 additional sites will be needed to accrue 100 subjects (50 African American and 50 Caucasian) over a 24 month accrual period. The study agents will be administerd at the following doses: apalutamide 240mg orally once daily, abiraterone acetate 1000mg orally once daily, and prednisone 5 mg BID in 4-week cycles throughout the treatment period. Fifty (50) patients will be enrolled in each group (AA and Caucasians). The proportion of patients who experience PSA decline of 30%, 50% and 90% will be estimated with exact 95% confidence intervals based on the binomial distribution will be computed. In addition, post therapy changes in PSA will be explored as a continuous outcome. The Kaplan-Meier product limit method will be used to estimate the rPFS, biochemical PFS and overall survival distributions.
An immunotherapy study combining ipilimumab and evofosfamide for the treatment of patients with confirmed metastatic or locally advanced prostate cancer, metastatic pancreatic cancer, melanoma or human papillomavirus (HPV) negative squamous cell carcinoma of head and neck that have failed to respond to standard therapy, progressed despite standard therapy, for which standard therapy does not offer the potential for increased survival.
This research study is studying the safety and tolerability of an investigational combination of drugs, radium-223 plus pembrolizumab as a possible treatment for castration-resistant prostate cancer. The interventions involved in this study are: - Radium-223 - Pembrolizumab
This research study is studying a combination of drugs as a possible treatment for castration-resistant prostate cancer. The interventions involved in this study are: - Docetaxel (a type of chemotherapy) - Apalutamide (the study medication, also known as ARN-509) - Prednisone (a corticosteroid given to prevent reactions to docetaxel). - Leuprolide acetate (also known as Lupron, a GnRH agonist or similar drug which is standard of care, causes chemical castration which greatly lowers the level of testosterone in the body)
The primary objective of the study is the matching of sensitivity, specificity, the negative predicate value and the positive predictive value of Contrast-Enhanced Ultrasound (CEUS), Shear Wave Elastography (SWE) and the combination to detect clinically significant prostate carcinoma foki. Conventional ultrasound is insufficient to safely display prostate carcinoma. Therefore, other imaging agents are recently added to improve the detection of tumor foci. These include innovative imaging ultrasound methods and multiparametric MRI.
