Filter by:This research study is comparing the use of a new form of hormonal therapy used with radiation as a possible treatment for intermediate risk prostate cancer. More specifically, this research would help determine whether this new form of hormonal therapy is as effective as the standard hormone therapy while also preserving erectile function.
MMR-deficient cancers of any histologic type appear to be very sensitive to PD-1 blockade with pembrolizumab, and similar data are also beginning to emerge for nivolumab and other immune checkpoint inhibitors. Among the MMR-deficient cancers, the best antitumor responses are often associated with high microsatellite instability (MSI-H status), higher tumor mutational burden (TMB), and higher predicted neoantigen load. Prevalence estimates of MMR deficiency across solid tumor types range from 1% to 20% depending on the type of malignancy. In prostate cancer, 1-3% of unselected cases harbor MMR deficiency and/or microsatellite instability. For men who previously received definitive treatment for prostate cancer and subsequently develop detectable prostate specific antigen (PSA) levels, the clinical state is known as biochemically recurrent prostate cancer. The current standard of care treatment for patients with biochemically recurrent prostate cancer is either surveillance or androgen deprivation therapy (ADT). ADT has not been shown to provide a survival benefit in this setting, and the decision to initiate ADT will depend on patient preference and perceived risks of the disease. A non-hormonal therapy such as nivolumab would provide an alternative to ADT in patients with biomarker selected (i.e. dMMR, MSI-H, high TMB, or CDK12-altered) biochemically recurrent prostate cancer.
Quantitative parameters obtained with dynamic whole body imaging using positron emission tomography (PET) can provide additional and complementary information to standard PET. Dynamic imaging allows for better understanding of the behavior of the radio-pharmaceutical because it can be followed over time. Thought to be difficult to perform with currently available clinical equipment that can affect the clinical workflow, it has recently shown to be feasible. We want to test the feasibility of this imaging technique and evaluate its utility in identifying lesions with three different radio-pharmaceuticals as compared to standard static PET. This study will also determine the clinical impact of DWB PET on participant management by comparing the overall qualitative assessment performed by nuclear medicine physicians between the standard PET images and the DWB ones.
This study is to compare the outcomes of robotic-assisted laparoscopic radical prostatectomy (RARP) and laparoscopic radical prostatectomy (LRP) for prostate cancer treatment in terms of perioperative surgical, functional and oncological outcomes.
Various approaches are currently being developed for prostate cancer immunotherapy. However, a major challenge facing the development of cancer immunotherapy is the identification of tumors that would best respond to this type of treatment. Different studies suggest that prostate cancer more likely to progress are more infiltrated by exhausted T cells expressing the cell surface protein PD1 (Programmed cell death 1). Therefore, there is a strong rationale for selecting patients at higher risk of progression for testing the efficacy of anti-PD1 therapy. High glucose metabolism as detected by fludeoxyglucose F18 (FDG)-positron emission tomography (PET) (18FDG-PET) imagery is an innovative biological biomarker-based method to identify patients at higher risk of recurrence and early failure to hormonotherapy. Recent study demonstrated that high intra-prostatic 18-FDG-uptake was associated with higher Gleason grades. Therefore the one third of Gleason ≥ 8 prostate cancer patients with higher 18FDG uptake would be ideal candidates for early immunotherapy treatments based on anti-PD-1 such as pembrolizumab. The study aimed to identify biomarkers predictive the response to Pembrolizumab given prior to radical prostatectomy in participants with primary prostate cancer at high risk of progression.
It is a phase I study of radical hypofractionation delivering one single fraction of SBRT in patients with low- and favorable intermediate-risk prostate cancer that will undergo placement of the SpaceOAR hydrogel prior to treatment. Our hypothesis is that treatments can be safely delivered in one single fraction using SBRT provided the separation between the prostate and rectum is increased using the hydrogel
This project seeks to use advanced imaging (specifically, positron emission tomography/computed tomography [PET/CT]) to detect, locate, and characterize recurrent disease in the setting of patients with prostate cancer.
Active Surveillance (AS) is a treatment option in patients with favorable risk prostate cancer. According to the current guidelines patients are monitored by prostate specific antigen (PSA) testing (every 3 months) and regular re-biopsies. Due to histological reclassification and/or patient noncompliance a high number of patients discontinue AS. Nonetheless, because of an increasing number of diagnosed early stage tumors overdiagnosis and overtreatment of patients has become a major clinical problem. Therefore AS is a promising and important tool for patients with low and intermediate risk prostate cancer. Multiparametric MRI (mp-MRI) in combination with radiomics analysis, MR-guided biopsies, and molecular markers are promising tools to optimize patient selection and observation during AS. This prospective, single arm, multicenter phase II study evaluates mp-MRI, radiomics, MR-guided biopsies and molecular markers for AS with the primary endpoint of reducing discontinuation based on histologic reclassification. At the end of this study the results may allow defining a MRI-based pathway to identify and monitor patients suitable for AS supported by radiomics. Thus, the high rate of discontinuation due to misclassification at initial diagnosis will be reduced. Additionally, this strategy will allow reducing over-treatment of clinically insignificant PCA, and on the other hand, increasing early treatment of higher-risk disease. Monitoring by mp-MRI will reduce the number of prostate biopsies and cores per patient during AS, and thus increase the patient compliance. Finally, such a strategy will reduce the economic burden of treating insignificant prostate cancer.
Background: People with prostate cancer usually have their cancer imaged with a CT scan and bone scan. They then have their prostate gland removed. Researchers want to test a scan that might predict if prostate cancer will return after this surgery. Objective: To test if a PET/CT scan before the prostate gland is removed can predict if prostate cancer will return. Also, to test if this approach is better or worse than the usual approach for prostate cancer. Eligibility: Men ages 18 and older with prostate cancer that appears to be contained within the prostate but is at risk of having spread Design: Participants will be screened with: - Medical history - Blood tests - CT and MRI scans: Participants will lie in a machine. The machine will take pictures of the body. - Bone scan Participants will have a radiotracer injected into a vein. They will have a PET/CT scan of their whole body 60 90 minutes later. During the scan, they will lie on their back and stay still. Within 60 days after the scan, participants will have surgery. This will remove the prostate gland and lymph nodes around it. Some tissue will be used for genetic testing. If the PET/CT scan suggests the cancer has spread, participants may need to have another biopsy within 60 days after the scan. After surgery, participants will have follow-up visits for 5 years. They will have 5 visits the first year and 2 the second. Then they will have visits once a year. If participants cancer returns, they will have repeat PET/CT scans.
This study will examine the efficacy of Men Moving Forward (MMF), a four-month community-based lifestyle intervention designed for AA PC survivors. MMF is rooted in the evidence-based Moving Forward lifestyle intervention developed with and for AA breast cancer survivors. This intervention was adapted in collaboration with AA PC survivors. It will offer twice weekly sessions aimed at supporting adherence to the ACS nutrition and physical activity guidelines to promote improved body composition (i.e., decreased adiposity, increased lean mass).
