To characterize and quantify immune cells expressing the Interleukine 4 induced gene 1 (IL4I1) immunosuppressive enzyme in the blood and in tissue of melanoma patients (primary tumor, sentinel lymph nodes and cutaneous metastases). Then, to compare the results obtained in different clinical settings: - in cases of progression of the disease slower or faster compared to the prognosis established by clinical and pathological data - before and after treatments with immunotherapy (anti Programmed Death ligand 1 (anti-PD1) or anti-PD1 and anti Cytotoxic T Lymphocyte associated protein 4 (anti-CTLA-4)) and...
This study seeks to determine the impact of focused ultrasound (FUS) on the composition of the tumor extracellular microenvironment. Researchers will evaluate regions that are very abnormal, as well as regions that have less evidence of disease. A sub-portion of each of these areas will be targeted by focused ultrasound. Microdialysis catheters will then be placd into each region that has and has not been exposed to FUS (total of 4 catheters) to determine how FUS impacts the the brain and tumor extracellular metabolome, including concentration of routine drugs systemically administered prior to, and during surgery. Researchers hope...
EVIDENT's aim is to test if ex vivo drug screening can predict whether patients with solid cancers will respond, or not respond, to standard care treatments. Patients undergoing standard care surgery to excise their tumour, those undergoing a biopsy, or those having a fluid aspirate of a solid tumour with surplus tissue available after diagnostic use will be eligible for this study. The specimen will then be assessed with ex vivo drug screening utilising all standard therapies and therapies that are more novel and in early stages of development. The results of the ex vivo drug screen will be compared to the cancer's actual response...
Functional precision medicine (FPM) is a relatively new approach to cancer therapy based on direct exposure of patient- isolated tumor cells to clinically approved drugs and integrates ex vivo drug sensitivity testing (DST) and genomic profiling to determine the optimal individualized therapy for cancer patients. In this study, we will enroll relapsed or refractory pediatric cancer patients with tissue available for DST and genomic profiling from the South Florida area, which is 69% Hispanic and 18% Black. Tumor cells collected from tissue taken during routine biopsy or surgery will be tested.
Caregivers of pediatric brain tumor survivors may develop high levels of psychological distress, mostly depression and anxiety, with effects comparable to those of a traumatic event. Several studies suggest that Eye Movement Desensitization and Reprocessing could be a promising treatment in similar clinical populations (i.e. adults with brain tumor), but it has never been used for caregivers of pediatric brain tumor. The aims of the present study will be to test the feasibility of the Eye Movement Desensitization and Reprocessing Integrative Group Treatment Protocol for caregivers of pediatric brain tumor survivors in a clinical...
NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human...
This study aims to assess the diagnostic performance of a new fast MRI sequence named Neuromix compared to routine clinical MRI for brain tumor in pediatric patients
The aim of this pilot study is to explore the utility of a new imaging technique, called Field Cycling Imaging (FCI), in postoperative low grade gliomas. The main question it aims to answer is if FCI can differentiate subtypes of low grade gliomas. Participants will have one FCI scan.
This pilot clinical trial studies fluordeoxyglucose (fludeoxyglucose) F-18 (FDG) positron emission tomography (PET)/computed tomography (CT) in monitoring very early therapy response in patients with glioblastoma. Diagnostic procedures, such as FDG PET/CT, may help measure a patient's response to earlier treatment. Chemotherapy can induce very rapid changes to the tumor's glucose consumption which can be measured with imaging. FDG PET/CT shortly after the start of therapy may help identify very early therapy response in patients with glioblastoma.
This is a multicenter pilot randomized controlled trial, with an active control condition, of the feasibility, acceptability, and preliminary efficacy of EndeavorRx in a cohort of survivors of acute lymphoblastic leukemia or brain tumor ages 8-16 who are > 1 year from the end of therapy.
