Filter by:Radiotherapy (RT) is an established treatment option for localized prostate cancer (PCa), with cure rates similar to those of radical prostatectomy. In the last decade, conventionally fractionated RT (1.8-2.0 Gy per fraction to 78-80 Gy) has been replaced by moderately hypofractionated RT (2.3-3.65 Gy per fraction to 56-70 Gy). The rationale behind this change is the scientific level 1 evidence that a higher dose per fraction may improve the cost-benefit of RT due to the specific radiobiology of PCa (a lower alpha/beta than that of adjacent healthy tissues). Additionally, there is a practical advantage both for patients and the radiation department due to a reduced number of fractions. More recently, extreme hypofractionation or stereotactic body radiotherapy (SBRT) (7-9.5 Gy per fraction to 36-43 Gy in 4-7 fractions) has been introduced as RT modality, and proved to be an effective and safe treatment option for patients with low and intermediate clinically-localized PCa, with similar incidence of late toxicity and 5-year disease free survival outcomes when compared to hypofractionated and conventional radiotherapy regimens. International guidelines endorse extreme hypofractionated SBRT as routine treatment option for low and intermediate risk PCa patients. For high-risk prostate cancer, preliminary results of ongoing prospective studies are promising, but these data are not yet mature enough to recommend extreme hypofractionated SBRT in high-risk prostate cancer. Upon this, ongoing prospective trials handle strict eligibility criteria hereby selecting patients with few comorbidities. This may not necessarily fully reflect the real life patient population. Indeed, patients with a large prostate size, a history of transurethral resection of the prostate (TURP), or 'significant' urinary baseline symptoms may be at risk for experiencing increased toxicity. Based on this concern, these patients were excluded from ongoing clinical trials. However, whether these patients will really develop more toxicity, is a theoretical concern, not yet based on clinical evidence. It is our hypothesis that using modern radiotherapy such as volumetric arc therapy (VMAT) and image-guided radiotherapy (IGRT) - both standard technologies at the Radiation-Oncology department in Leuven University Hospitals - extreme hypofractionated SBRT can be successfully implemented in the treatment of intermediate risk and a select group of high-risk PCa patients and/or patients with pre-existing urinary morbidity.
In this study, the investigators aim to form a Brazilian national prospective active surveillance cohort of patients with low-risk prostate cancer in the public health system. The investigators aim to demonstrate data on the pathological reclassification rate, treatment-free survival, among others. This cohort aim to evaluate and validate the active surveillance strategy in Brazil.
The purpose of this study is to evaluate the effect of pneumatic compression on post-induction hypotension in elderly patients undergoing robot assisted laparoscopic prostatectomy.
Inherited predisposition to prostate cancer (PC) has been defined by strict clinical criteria or by genetic profile determined by the presence of a deleterious mutation of deoxyribonucleic acid (DNA) repair genes related to breast/ovarian cancers (such as BRCA2, BRCA1) or by PC specific variants (HOXB13 and 8q24CASC19). But currently, recommendations for management and mitigation of PC risk with early screening just emerge for BRCA2 mutation carriers. Our study compares a PC screening strategy based on an annual prostate specific antigen (PSA) test and a clinical examination to a strategy that also includes an annual multiparametric magnetic resonance imaging (mpMRI). It focus not only on 440 unaffected men carrying the BRCA2 mutation, but also on 440 unaffected men member of hereditary PC families with an unidentified mutation or carriers of a mutation of another gene that predisposes to PC, for a total number of participants included of 880. This project estimates the benefits and inconveniences to extend the proposed early diagnosis procedure from unaffected men with BRCA2 mutation to all unaffected men meeting criteria of an inherited predisposition. It should allow to diagnose PC at a more curable stage, and to establish national recommendations for the management of men with high genetic risk of PC useful in clinical routine, depending on typology of the genetic risk. This project aims to efficiently diagnose them, without performing unnecessary biopsies, at curable stage of the disease. It should reduce their risk of death from this cancer known to be of bad prognosis at an advanced stage.
The purpose of this study is to evaluate pharmacokinetics, safety and tolerability profile of BZ371A topically administered in healthy patients.
Prostate cancer is the most diagnosed cancer in African American men and the second-leading cause of cancer-related death. The prostate-specific antigen (PSA) test is an early detection screening measure for prostate cancer. Greater PSA uptake among African Americans may reduce the disproportionate mortality burden of this disease. However, knowledge about prostate cancer and uptake of PSA screening remain low among African American men. To address this inequity, innovative team science approaches are required. This project proposes to develop and test the first-of-its-kind Prostate Cancer Genius App to improve knowledge of prostate cancer risk and symptoms, and deliver tailored navigation to complete a home-based PSA test. The primary goal of this study is to evaluate the feasibility of the Prostate Cancer Genius App in a 30-day pilot randomized control trial compared to an existing app developed by the U.S. Department of Health & Human Services (Prevention Taskforce App). African American men from Oklahoma, aged between 55 and 69 (N = 80), eligible for the PSA test will be randomly assigned 1:1 to receive either app. Three dimensions of app feasibility will be assessed: (1) preliminary efficacy, evaluated via post-intervention differences in prostate cancer knowledge, (2) app engagement and accessibility, measured via self-report questionnaires, and (3) app acceptability, explored via semi-structured qualitative interviews. Finally, the investigative team will explore post-intervention PSA screening rates and identify predictors of screening/not screening across both arms. The successful demonstration of feasibility for the Prostate Cancer Genius App within Oklahoma will support expanding this intervention to African Americans nationwide.
This is a Phase II prospective sing-arm trial that is recruiting 60 participants from patients that have biochemical failure after radical prostatectomy with local or regional recurrence proven by PSMA PET. Participants of this study will receive molecular imaging informed radiation dose escalation to site of recurrent disease and de-escalation to uninvolved areas. Participants will be follow-up as per standard of care up to 5 years post-treatment.
The purpose of this research is to determine whether a 16-week culturally tailored, technology-based, aerobic and resistance exercise intervention improves cardiovascular risk factors in Black men diagnosed with prostate cancer and are undergoing androgen deprivation therapy (ADT), and whether it will also improve physical fitness and function, body composition, and outcomes such as quality of life, cancer symptoms, and self-esteem. Participants in this study will be randomly assigned to one of two groups: 1) Aerobic and resistance exercise, or 2) Usual care.
The purpose of this research is to determine whether a 16 week, home-based, aerobic and resistance exercise intervention will increase physical activity levels in Black and Hispanic breast, colorectal, or prostate cancer patients. The names of the study interventions involved in this study are: - Supervised aerobic and resistance exercise (SUP) - virtually supervised 16- week aerobic and resistance exercise performed at home via Zoom. - Unsupervised aerobic and resistance exercise (UNSUP) - home-based 16- week aerobic and resistance exercise. - Attention control (AC) - 16-week home-based stretching.
Active surveillance (AS) is becoming an increasingly common treatment option for men who have been diagnosed with localised low-grade prostate cancer (PCa). Low-grade disease is commonly noted by clinicians to be clinically insignificant cancer but remains a psychological burden to many men in this cohort. There is consensus that regular review is required for men on AS so that early treatment can be undertaken if there is disease progression, and to support men living with a cancer diagnosis. Some AS protocols, including National Institute for Clinical Excellence (NICE), advocate the use of MRI as a regular part of the monitoring pathway. Unfortunately, access to MRI for AS, within the current health care environment in the UK, is limited due to increasing demand for primary diagnostic examinations, particularly in the post pandemic recovery phase. Emerging technologies in ultrasound imaging may, however, add another diagnostic tool to monitor disease for patients on AS. This proof of concept study is to evaluate whether new multi-parametric ultrasound techniques can safely reduce the number of MRIs required for effective AS. Men being investigated for PCa will be invited to undergo an ultrasound examination of their prostate, via the rectum, in addition to the diagnostic MRI undertaken as part of normal care. The findings of the ultrasound will be directly compared with the MRI and any subsequent biopsy samples taken as part of routine care. Those who then progress onto AS will be invited to undergo regular rectal prostate ultrasound examinations. These will be compared with previous imaging for signs of change. This study will also evaluate the changing role of practitioners who will be using new technologies and making decisions about disease progression. The ability to implement new techniques will be assessed. All imaging will be undertaken at Castle Hill Hospital over a 24-month period from commencement of the study.
