Filter by:The purpose of this study is to collect a urine sample from patients with prostate and urothelial (bladder) cancer and healthy volunteers who do not have cancer, so that researchers can perform studies on microcellular structures called exosomes that may eventually lead to a new type of urinary biomarker test for prostate and urothelial cancer.
The purpose of this research study is to measure the hypoxia (low oxygen condition) in prostate cancers and its effect in survival. In this study, investigators will assess hypoxia by magnetic resonance imaging (MRI) and create a hypoxia score. Investigators will study the hypoxia score and how it correlates (if any) to the disease aggressiveness as well as its effect on the treatment outcomes.
Phase III study that aims to evaluate the necessity of prophylactic antibiotics use after HDR brachytherapy in the treatment of prostate adenocarcinomas.
The overall objective of this study is to acquire ultrasound images, spectral data and prostate tissue biopsy cores using the ClariCore System via a transperineal approach.
A diet consisting of a reduced quantity of the essential amino acid methionine sensitizes cancer cells to radiation therapy and reduces metastasis formation and disease progression in mice. However, to date, dietary restriction of methionine has not been tested in combination with radiation therapy in humans as a strategy to improve patient outcomes.
Background: Immunotherapy drugs help the body to fight cancer. Scientists think that combining some of these drugs will make them work better than when used alone. This may be true for many types of cancer, including castration-resistant prostate cancer (CRPC). Objective: To test if the combination of the drugs BN-brachyury, M7824, N-803, and Epacadostat is safe and shrinks tumors. Eligibility: People ages 18 and older with CRPC or another metastatic cancer Design: Participants will be screened with: - Medical history - Physical exam - CT or MRI scans - Possible bone imaging - Blood, urine, and heart tests - Possible tumor biopsy Participants will be treated with a 2-, 3- or 4-drug combinations of the following study drugs in 2-week cycles: - Participants will receive M7824 by IV once every 2 weeks. - Participants will receive N-803 by injection once every 2 weeks. They will record any skin changes at the injection site in a diary. - Participants will receive BN-brachyury as 4 injections to different limbs. They will get the first 3 doses 2 weeks apart. Then they will get doses every 4 weeks for 6 months, then every 3 months for 2 years, then every 6 months. - Participants will take Epacadostat orally every 12 hours. They will keep a pill diary. Participants will have physical exams and blood and urine tests at the start of each cycle. They may have scans every 12 weeks. Participants will continue treatment until their disease gets worse or they cannot tolerate the side effects. Participants will have a follow-up visit 4-5 weeks after they stop treatment. They will have a physical exam and blood tests. They may be asked to return for scans every 3 months.
This is an investigator initiated study to test the efficacy of an upright MRI (Magnetic Resonance Imaging) for the screening of prostate cancer. The purpose of this study is to compare Upright MRI as a technique to PSA (Prostate Specific Antigen) and current MRI imaging. It will take place at Mount Sinai Hospital, and last for a total of about 5 years. Eligible patients will be determined by the urologist. The target population is men who are at risk for prostate cancer, as determined by the urologist. Diagnostic criteria will include elevated PSA and an abnormal digital rectal exam (DRE). After patients are screened and determined eligible, they will be asked to have a seated MRI using the Indomitable Magnetic Resonance Imaging Scanner, Ex vivo magnetic resonance imaging using 0.6 T strength, as well as a standard of care closed 3T MRI. After each scan, the patient will be given a series of questionnaires to assess their comfort level during the scan. Patients will be followed every 6 months after completion of (or early withdrawal from) study enrollment until 5 years.
Previous research into metabolic and hypoxic markers has found evidence of preclinical impact of exercise on prostate tumor blood flow and oxygenation in rodents . As radiotherapy is a frequently used and effective therapy for and that sufficient oxygenation is decisive to the effect of radiotherapy, an underlying hypothesis that aerobic exercise might improve treatment efficacy of radiotherapy in prostate cancer is put forward. This study has a potential challenging intervention, but a potential very high gain as it includes active patient participation to significantly improve outcome of radical radiotherapy.
Through this study the investigators seek to build up a repository of prostate ultrasonography videos and prostate MRI scans to enable research into novel anatomical registration techniques. These data will facilitate the development of improved technology that enables targeting of tumours seen on MRI using free-hand biopsy techniques, without the need for a gantry or overlaid perineal grid.
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.
