Filter by:Prostate cancer is the second most common cancer in male cancer globally and ranked third in Hong Kong. While androgen deprivation therapy (ADT) is the backbone treatment for advanced prostate cancer, it could lead to obesity, metabolic syndrome and increased cardiovascular mortality. Previous studies showed that ADT patients have different gut microbiome compared to non-ADT patients and the gut microbiome might be related to the metabolic changes. However, the underlying mechanism of these metabolic complications is still not fully understood. This study aims to investigate the relationship and related mechanism between the changes in gut microbiomes and ADT-related metabolic change in prostate cancer patients.
The study drug, radium-223, gives off radiation that helps to kill cancer cells in the prostate. It is already available for patients to receive as a treatment for prostate cancer that has not responded to testosterone lowering treatment and has spread to the bones. This type of cancer is called metastatic castration-resistant prostate cancer, also called mCRPC. Sometimes, researchers continue studying an available treatment to learn more about how it affects patients' daily lives. In this study, the researchers want to learn more about how radium-223 affects the patients' ability to do their daily tasks. The patients in this study will already be receiving treatment with radium-223 as part of their routine care. The tests and measurements in this study will be done by the patients' own doctors. The researchers will collect information about the patients' treatment and results. The study will include patients with mCRPC who have at least 2 tumors in their bones. These patients will have recently started treatment with radium-223. The patients will have also had surgery or treatment to lower their testosterone levels. But, the treatment did not help their cancer. The study will include about 105 men in Colombia who are at least 18 years old. All of the patients will receive radium-223 through a needle put into the vein, also called an intravenous injection. They will visit their doctor's office up to 8 times during 28 weeks. At these visits, their doctors will ask how they are feeling and what medications they are taking, and will take blood samples. The doctors will also give the patients surveys about their physical, social, and emotional health and about the symptoms of their prostate cancer.
This will be a Phase 1, open label, 2-sequence, crossover study to establish the BE of the current commercial formulation (Generation 3.1 talazoparib capsules) to the proposed talazoparib liquid-filled soft gelatin capsule (soft gel capsule) formulation after multiple dosing under fasting conditions in participants with advanced solid tumors. In addition, the effect of food on the PK of the proposed talazoparib soft gel capsule formulation will be evaluated in fixed sequence after the 2 BE assessment periods.
The complex relationship that exists between physical and mental health in prostate cancer is increasingly being understood. Psychiatric symptoms are common in this group and have important consequences for the quality of life and cancer outcomes for patients with prostate cancer. However, less is understood about the severity of disease and which patient factors and treatment options are risk factors for developing problems. Additionally, the impact these conditions have on problems such as urinary incontinence or sexual function is less well understood. The investigators anticipate that different patient characteristics and treatment options increase an individuals risk of developing problems after a prostate cancer diagnosis. Therefore, this study aims to further investigate these specific factors to improve follow up care in patients with prostate cancer. This observational study will follow up newly diagnosed prostate cancer patients for a period of 12 months to evaluate these outcomes. Participants will be identified across seven hospitals in London and South England. After being recruited participants will be invited to undergo repeated online or postal questionnaires at baseline, 3, 6, 9 and 12 months. These will assess depressive and anxiety symptom load, body image issues, fear of recurrence, masculinity perception and functional symptoms (including urinary, bowel and sexual symptoms) load. Analysis of these findings will allow for identification of 1) Which subgroups of patients appear to have worse mental wellbeing and quality of life outcomes, and 2) How mental health issues impact functional outcomes. This will provide important information for guiding future research within the subject area and further inform clinicians about these issues.
Radiotherapy (RT) of the abdomen and/or pelvis is known to cause acute and late gastrointestinal (GI) toxicities. While radiation dose and volume are known risk factors for developing such side effects, recent evidence suggests patterns of disturbance in the composition of the GI microbiota - so called "dysbiosis" - may also promote the host's susceptibility to GI toxicities through impaired intestinal barrier function and inflammation. The IMPRINT-study aims to expand the current knowledge on the role of intestinal bacteria and their metabolites involved in the pathophysiology of radiation-induced GI toxicities by longitudinally examining the microbiota composition (feces), the associated metabolome (blood, feces and urine) and bacterial extracellular vesicles (BEVs) (blood and feces).
Veterans between the ages of 50-75, who are having a prostate biopsy, will be recruited for their permission to collect an extra biopsy core for RNA-sequencing. If the participants' treatment decision is Active Surveillance, they will be enrolled into the intervention phase of the study. They will receive supplementation with Vitamin D3 (4,000 IU) daily with repeat (surveillance) prostate biopsy one year later. At that time an extra prostate sample core will be collected for RNA-sequencing to determine changes over time. Measurements for allostatic load (body stress/inflammatory markers) will also be collected at the time of enrollment and at the repeat prostate biopsy visit.
The purpose of this study is to evaluate the change of the internal carotid artery blood flow according to the steep trendelenburg position and pneumoperitoneum in patients undergoing robot-assisted laparoscopic prostatectomy.
This is a prospective, single-center, open-label pilot study of 68GA-PSMA-11 given at a single time prior to PET/CT imaging in men with localized high risk prostate cancer or biochemical recurrence. The imaging agent (68 Ga-PSMA 11 will be administered on an outpatient basis. It will be administered prior to the PET/CT imaging. The objective is to evaluate the distribution of 68GA-PSMA-11 in tissues and to determine if this alters the planned clinical management.
Rationale: Current imaging techniques for the detection and grading of prostate cancer are imperfect, leading to unnecessary biopsies, suboptimal treatment decisions and missed clinically significant cancers. The hypothesis of this study is that computer assisted analysis of 3D multiparametric ultrasound (mpUS) images can accurately detect, grade and localize prostate cancer. 3D mpUS may then become a more cost-effective and more streamlined imaging strategy than the current standard: mpMRI. Objective: The primary objective is to collect high-quality 3D mpUS and histology data, to train and improve the classifier algorithm with the goal of achieving an accurate ultrasound imaging tool for the detection of clinically significant prostate cancer. Secondary objectives are related to the preliminary assessment of the performance of 3D mpUS with computer assisted analysis. Study design: This is a prospective, multi-center study in men with a suspicion of prostate cancer who are scheduled for prostate biopsies, and men with confirmed prostate cancer who are scheduled to undergo a radical prostatectomy. Prior to prostate biopsies or the radical prostatectomy, 3D mpUS imaging will be performed. The ultrasound images will be analyzed and used for algorithm training using the biopsies and/or prostatecomy specimens as gold standard. Additional research coupes of pathology material (both biopsies and radical prostatectomy specimens) from study subjects will be anonymized and separately analyzed and stored in a central, independent institution. The outcome of the 3D mpUS analysis and the additional pathology evaluation are for research purposes only and will not interfere with standard patient care. Study population: 1) Male patients of age ≥18 suspected for prostate cancer who are scheduled for systematic and/or targeted biopsy after mpMRI examination. 2) patients of age ≥18 with confirmed prostate cancer who are scheduled for radical prostatectomy. Main study parameters/endpoints: - Gleason/Grade group scoring based on histology. Using histology as the reference standard the accuracy of the algorithm will be optimized to be differentiating between benign tissue and various grades of malignancy. - Localization and size of lesions at full-gland histology in the subset of patients undergoing radical prostatectomy. Correlation in tumour size and location will be optimized between 3D mpUS findings and histology of the full gland. For the secondary objective, preliminary assessment of the performance of 3D mpUS, the following endpoints are evaluated - Among all clinically significant detected cancers confirmed by histology, the proportion of these cancers that would have been detected by 3D mpUS will be calculated. The number of false positive findings by 3D mpUS both as an absolute count and expressed as a mean rate per patient. - The concordance in the detection and grading of abnormalities between mpMRI and 3D mpUS by examining the frequency and type of disagreements and calculating the kappa statistic.
This is a single-arm, prospective, interventional study in cancer survivors and patients to examine the feasibility of a mobile health application, Elly (Elly Health Inc.), to reduce levels of anxiety, stress, loneliness, and social isolation. Participants will be given access to the Elly phone application developed by Elly Health Inc. and will be asked to complete questionnaires measuring quality of life at multiple timepoints during the study.
