Filter by:This study is evaluating whether adding stereotactic radiotherapy (a new, more focused type of radiotherapy) to treat all the tumours that are present will improve outcomes or not compared to drugs alone for patients who are negative on conventional imaging and positive on PSMA PET scan
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.
de Novo metastatic prostate cancer with limited metastatic spread benefits from local radiotherapy to the prostate. Two different fractionation schedules will be tested.
The purpose of this study is to evaluate a new ultrasound technique. This technique may provide additional and improved information about the stiffness and sizes of the internal structures of your prostate in order to improve the guidance for a targeted biopsy. The investigational, custom-designed probe and needle guide will be used to produce images of your prostate and provide guidance for up to 4 additional biopsy samples (cores) prior to a standard magnetic resonance (MR) ultrasound fusion biopsy procedure. Above the time required for the MR ultrasound fusion biopsy, this study will take up to 30 additional minutes of time for collection of the investigational device guided collection of biopsy samples Risks of participation include increased time under anesthesia (to collect additional biopsies) and slight heating of tissue.
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.
Single-center evaluation of all patients treated for primary localized prostate cancer with focal HIFU from November 2009 to December 2016. To evaluate midterm oncological outcomes of focal HIFU therapy in low an intermediate risk prostate cancer.
This research study is designed to determine if targeted Magnetic Resonance Imaging (MRI) Ultrasound (US) fusion biopsy is better than the standard of care ultrasound guided biopsy alone in diagnosing subjects with clinically significant prostate cancer with MRI visible lesions. This study will consist of comparing the standard of care (ultrasound guided prostate biopsy) with the protocol biopsy which consists of an ultrasound guided prostate biopsy and a MRI/US fusion tracked prostate biopsy.
A randomized comparison clinical trial will be conducted in laparoscopic radical prostatectomy patients in the Weinberg PACU at the Johns Hopkins Hospital. 50 patients will be recruited and randomly assigned by a table of random numbers to either the music listening group (n=35) or the relaxation breathing group (n=35).
