Filter by:The objective of this study is to obtain human blood CD34+ hematopoietic stem/progenitor cells (HSPCs) to reconstitute a match human immune system in our PDX model. The hypothesis is that by using matched leukocytes and PDX from the same patient, rejection of the PDX by the host immune system will not be observed and therefore a preclinical model to study immunotherapy can be developed to study, understand and improve upon our current therapies. HSPCs will be collected from bone marrow aspirate obtained from a bone marrow biopsy. The secondary objective is to use patient tumor biopsy samples or circulating tumor cell samples to develop additional preclinical models of GU cancers, particularly prostate cancer, that are clinically relevant by generating additional PDXs.
Background: Prostate cancer is the most common non-skin cancer in U.S. men. Treatments for early or less aggressive disease are limited. Researchers want to test a device that destroys cancerous tissue with laser energy. They want to see if using it with ultrasound is more comfortable than using it with magnetic resonance imaging (MRI). Objectives: To test a cooled laser applicator system to treat prostate cancer lesions. To see if ultrasound imaging is a practical and feasible treatment with laser ablation for focal prostate cancer treatment. Eligibility: Men at least 18 years old with prostate cancer seen on MRI that has not spread in the body. Design: Participants will be screened with standard cancer care tests. These can include physical exam, lab tests, and MRI. For the MRI, they lie in a machine that takes pictures. Participants will have a prostate biopsy. Needle samples will be taken from 12 places in the prostate. This will be guided by MRI and ultrasound, which is obtained through a coil in the rectum. Participants will stay at the clinic for 1 2 days. A cooling catheter (plastic tube) will be put in the bladder. Ultrasound will guide the laser applicator directly to the tumor. The cooling catheter will be removed. A different catheter will be put in the urethra to keep the bladder emptied. The next day, participants will have a physical exam and a PSA blood test. Participants will have 6 follow-up visits over 3 years. At each visit, they will have a physical exam and lab tests. At some visits, they will also have an MRI or other scans and a prostate biopsy.
The benefit of dose escalation in radiotherapy (RT) for biochemical control of prostate cancer is a clearly established fact based on the results of different published prospective trials. This benefit, acquired with three-dimensional conformal radiation technique is counterbalanced by an increase in urinary and gastrointestinal toxicity. The joint progress of dose planning systems and multileaf collimators (MLC) technology have enabled the Intensity Modulated Radiation Therapy (IMRT). Recently the contribution of "spacers" positioned in the septum between the rectum and the prostate could improve the functional results of IMRT in terms of rectal toxicity. The aim of the investigators study is to assess the dosimetric gain from the contribution of the implantable BioProtect balloon on organs at risk.
The purpose of this study is to evaluate the effectiveness of the two most established primary treatments for patients with clinically localized prostate cancer: radical retropubic prostatectomy, and external-beam radiotherapy. The primary aim is assessing biochemical disease-free survival, overall survival, and prostate cancer-specific survival. As secondary objectives quality of Life impact of treatments' side effects will be also assessed.
To evaluate the clinical impact of an online video simulator during the learning period of laparoscopic radical prostatectomy.
The purpose of this study is to assess the safety and effectiveness of natural killer (NK) cell and natural killer T (NKT) cell-based autologous adoptive immunotherapy in subjects with metastatic, treatment-refractory breast cancer, glioma, hepatocellular carcinoma, squamous cell lung cancer, pancreatic cancer, colon cancer or prostate cancer.
This study tests the safety and tolerability of autologous anti-PSMA gene-modified T cells (designer T cells) in hormone refractory prostate cancer.
This is a prospective phase II study of peri-operative docetaxel plus laparoscopic radical prostatectomy in patients with localized Gleason 7 pT2a-pT2b adenocarcinoma of the prostate and a risk of relapse after radical prostatectomy.
Praecis is currently conducting a 2000 patient Experience Study; this is a Phase IV commitment postmarketing safety study in the Food and Drug Administration (FDA) indicated population of patients receiving Plenaxis®. The purpose of the study is to estimate the incidence of immediate-onset systemic allergic reactions in the indicated population receiving Plenaxis® and to determine whether the hazard rate changes over time.
