The investigators will assess the incidence of Overactive Bladder/Detrusor Overactivity (OAB/DO) post-operatively in patients post robotic assisted radical prostatectomy (RARP) and to investigate whether fesoterodine will alter the incidence of OAB/DO in these patients. Additionally, the correlation between OAB symptoms and urodynamic DO will be analyzed.
Positron emission tomography using carbon-11 acetate (AC-PET) may help find local or distant metastases from prostate cancer. This clinical trial is studying how this imaging test may help influence the choice and extent of initial treatments, and subsequent treatments.
This randomized phase II trial studies how well tivantinib works compared to placebo in treating patients with metastatic prostate cancer. Tivantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This partially randomized phase I/II trial studies cabazitaxel with or without carboplatin in treating patients with previously treated prostate cancer that has spread to other areas of the body and does not respond to treatment with hormones. Drugs used in chemotherapy, such as cabazitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cabazitaxel alone or with carboplatin is more effective in treating prostate cancer.
This trial is to determine if prostate target delineation obtained through an ultrasound based system is equivalent in accuracy to the MRI image fusion, and if alignment correction vectors obtained from ultrasound imaging are of equivalent accuracy to orthogonal X-ray imaging for daily prostate positioning.
1. The investigators hypothesize that increasing radiation dose to the functional MRI-defined lesion in the prostate bed will result in an improved initial complete response (reduction in prostate-specific antigen (PSA) to < 0.1 ng/mL), which is related to long-term outcome biochemically. 2. Biomarker expression levels differ in the DCE-MRI enhancing and non-enhancing tumor regions (when applicable). 3. 10-15% of men undergoing RT have free circulating DNA (fcDNA) or tumor cells (CTC) that are related to an adverse treatment outcome. 4. Prostate cancer-related anxiety will be reduced in the MRI targeted SRT arm, because the patients will be aware that the dominant tumor will be targeted with higher radiation dose (compared to those pts who were treated on standard arm prior to its closure).
1. Delivery of directed hypofractionated targeted (HT) radiotherapy (RT) tumor boost to the dominant tumor lesion in the prostate as identified by multiparametric MRI will increase tumor eradication from the prostate. 2. Biomarker expression levels differ in the multiparametric MRI defined regions at high risk of harboring tumors that determine outcome. 3. 10-15% of men undergoing RT have Circulating DNA or tumor cells (CTC) that are related to an adverse treatment outcome. 4. Quality of life will not differ significantly between the treatment arms. 5. Prostate cancer-related anxiety will be reduced in the HTIMRT arm, because the patients will be aware that the dominant tumor will be targeted with higher radiation dose.
The hypotheses of this study are: 1. Delivery of single fraction Lattice Extreme Ablative Dose (LEAD) radiotherapy (RT) to the dominant tumor lesion(s) in the prostate as identified by multiparametric functional Magnetic Resonance Imaging is safe and feasible when given prior to standard prostate radiotherapy. 2. Biomarker expression levels differ in the functional MRI identified suspicious tumor regions and unsuspicious tumor regions. The investigators hypothesize that a significant source of variation in biomarker levels is due to tumor heterogeneity and that it is molecular abnormalities in the dominant tumor areas that are angiogenic and determine outcome.
This is a study to first establish feasibility of the study and then to register the treatment data of adult patients with a diagnosis of intermediate risk of prostate cancer presenting for definitive radiation treatment with either proton radiotherapy or Intensity Modulated Radiation Therapy (IMRT). The investigators propose to employ a hypofractionated strategy with our image guided treatment to further improve cancer control and decrease toxicity.
