Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to determine how to incorporate a smart water bottle to improve bladder filling for prostate cancer patients undergoing radiation therapy.

To evaluate the safety profile of FIRMAGON (to fulfill the regulatory authority's requirement of Intensive Drug Monitoring in Chinese patients with prostate cancer need androgen deprivation therapy [ADT] treated with FIRMAGON). Study Design This study is a multi-center, single-arm, non-interventional, prospective study among Chinese patients with prostate cancer and need ADT receiving treatment with FIRMAGON. This program will provide the minimum 6 doses and maximum 12 doses of FIRMAGON to enrolled patients during one-year follow-up. Patients who meet inclusion criteria and will or are accepting at least 6 self-financed doses treatment in hospital. Patients should return to the hospital for medical assessment every three months. The prescription of 6 (3 dose × 2 times) self-financed doses will be given by doctors after assessment, and the direct-to-patient pharmacy will distribute FIRMAGON to eligible patients (patients should bring the prescriptions and the last FIRMAGON boxes to get other doses). All enrolled patients will be followed up to collect safety information for one year from the 1st dose unless withdrawal of Informed Consent Form, discontinuation for 2 months, lost to follow-up, death, or termination due to other reasons, whichever comes first.

The present study is the last part of a larger project investigating the health, quality of life and function of men having received radical treatment for prostate cancer in 2014-2018. In this study, physical function and level of physical activity will be tested and registered in a selection of older men who participated in the foregoing parts of the project. Comparisons will be made to similar data from a population-based cohort, matched on age and education.

The proposal will explore a trial design called the cohort-multiple RCT (cmRCT) or as it has been recently coined, the Trials WithIn Cohorts (TWICS) design. This design has been used in a number of disease areas, both benign and cancer. Prostate conditions have been chosen since they are extremely common and if malignancy occurs the majority of men with the disease are regarded as living with a chronic condition due to its long natural history and in which innovative approaches, interventions, treatments or changes in management might have a significant patient benefit and impact on the NHS. It therefore fits the cmRCT design very well. Nonetheless, the lessons learned in this study will be of relevance to other disease spaces. The TWICS or cmRCT design is currently being used in elderly patients, risk of falls, depression, hip fracture, Yorkshire Health Study, scleroderma, breast cancer, colorectal cancer, bladder cancer and kidney cancer, to name a few. In total, a recent systematic review showed that there were 18 ongoing cmRCT studies with 6 in the UK. The acceptability and feasibility of the cmRCT in the prostate pathway will be tested. This is the first time this method will be tested and therefore piloted. In the first part of the study, the following will be evaluated. What is the accrual rate? What do patients and their healthcare professionals think of the cmRCT design? Is the data collected robust? What are the resource requirements of such a study?A number of novel interventions or changes in the pathway will then be tested and compared to standard care in the cohort that was recruited.

In this observational study researchers want to gather more information about the characteristics of patients treated with Radium-223 (Xofigo) who had survived over a long period of time prostate cancer that had spread to other places in the body and keeps growing even when the amount of testosterone in the body is reduced to very low levels (metastatic castration-resistant prostate cancer, mCRPC). In addition researchers want to identify the factors which may contribute to survival over a long period of time in those patients. Radium-223 (Ra-223) is an alpha particle-emitting radioactive agent approved for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC).

The primary purpose of this study is to evaluate the influence of HSD3B1 (1245C) germline variant and potential pharmacodynamic markers on abiraterone activity in participants with metastatic castration-resistant prostate cancer after unresponsive use of diethylstilbestrol.

This study will be a retrospective data analysis to compare outcomes between patients with chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC) who initiated enzalutamide and those who initiated abiraterone using the 100% Fee-For-Service Medicare claims data. The study will address the following objectives: Primary objective: To compare overall survival (OS) in patients with chemotherapy-naïve mCRPC who initiated enzalutamide vs. abiraterone Secondary objectives: To compare OS in patients with chemotherapy-naïve mCRPC who received only enzalutamide without any subsequent therapy vs. abiraterone without any subsequent therapy To compare treatment duration and time to subsequent therapy in chemotherapy-naïve mCRPC patients initiating enzalutamide vs. abiraterone

The generation of predictive models in radiotherapy has seen a significant increase. In 2017, Raymond published the largest systematic review of predictive prognostic models for biochemical relapse (BR), metastasis-free survival, and overall survival in patients with localized prostate cancer treated with radiotherapy (14), attempting to identify whether they were adequately developed and validated. He found 72 unique predictive models for external radiotherapy: 22 corresponding to BR risk, 20 corresponding to Cancer-Specific Survival, 10 corresponding to Overall Survival, and 20 for Disease/Metastasis-Free Survival detection. In his analysis, he highlighted a significant variation in the quality of these predictive models, understanding that they were developed prior to the existence of TRIPOD guidelines. In this regard, he pointed out that 54% of these models did not report their accuracy, and 61% of the models lacked validation (either internal or external). He also noted that they had limited follow-up (only 65% had follow-up beyond 5 years), that the treatment doses in these models were lower than current standards, and that the radiation techniques were different from current practices. Although in his final assessment, Raymond maintains that predictive models provide more certainty in predicting oncological outcomes than professional assessments, he considers it vital to validate these models for each population that wants to use them (the vast majority of these models are based on U.S. populations) or, even better, to generate predictive models specific to the local population while adhering to the TRIPOD guidelines. Probably due to the lack of validation in our patients for existing predictive models and/or the absence of predictive models originating from our population, in our routine clinical practice (Multidisciplinary Oncology Committees), phisycians do not apply any predictive models to patients diagnosed with localized prostate cancer.

Background: Prostate biopsies are essential to diagnose prostate cancer (PCa). Transrectal prostate biopsies (TR-PB) are commonly performed, however disadvantages include the requirement of antibiotic prophylaxis (AP) and higher complication rates than transperineal prostate biopsies (TP-PB). Guidelines still recommend the use of AP for TP-PB due to the limited evidence regarding complication rates after their omission. However, the rising rates of antibiotic resistance is of concern. The aim of this study was to compare the complication and detection rates of freehand TP-PB without AP versus TR-PB with AP. Methods: This single center retrospective study was performed in an academic hospital. TP-PB were introduced in 2019 and implemented as the main technique by late 2020. To compare the two techniques, data was collected for freehand TR-PB with AP between 2017-2018 and freehand TP-PB without AP between 2021-2022. The data from 2019 and 2020 were excluded to rule out the effects of the initial learning curve during the transition period. Primary outcome measure was post-biopsy complications occurring within 2 weeks, focusing on infectious complications. Secondary outcome measures were detection rates and upgrading/reclassification in the repeat biopsy in active surveillance (AS). Statistical analysis was performed using a Fisher exact or Chi-Squared test.
