Filter by:The purpose of the clinical study is to investigate whether the local delivery of bisphosphonate as a surgical adjuvant can decrease the chance of a giant cell tumor of bone coming back to the same location. The hypothesis is that the local administration of bisphosphonate will decrease the rate of the tumor returning compared to traditional aggressive surgical removal of the tumor.
Barrett's oesophagus is a transformation of the esophageal mucous membrane there intestinal metaplasia under the effect of gastro- esophageal reflux disease (GERD). This metaplasia can evolve in low grade dysplasia LGD) , high grade dysplasia (HGD) then invasive adenocarcinoma. The treatment of the HGD of the Barrett is the endoscopic treatment. It is about a superficial treatment of tumor without ganglionar invasion by definition. The endoscopic treatment of the Barrett began in the 2000s, and showed its long-term efficiency. The studied factors of recurrences are the length of the Barrett, the influence of the eradication completes of the Barrett besides the eradication of the dysplasia, as well as the duration of spacing of the procedures. An anatomical zone is particularly delicate to treat. It is about the anatomical junction between the oesophagus and the stomach appointed junction oeso-gastric or cardia or line Z. This almost virtual zone is the site of most of the recurrence. The first cause of the oesophagus of Barrett and of its transformation in HGD is the reflux. This reflux can be handled by medicinal action inhibitor of the pump with proton (PPI) or by surgery (hemi-fundo plicator). This reflux is probably the cause of the long-term recurrence found in the literature. The surgery is a good treatment of the reflux with however unsatisfactory long-term results. On the other hand, the surgery is little used after endoscopic treatment of a HGD not to compromise the surveillance and the detection of a second offense potentially masked in the surgical fundo-plicator. The endoscopic treatment of the expensive ebb because of the based necessary material too on a fundo-plicator is complicated with use in reason also of his cost. The medical treatment by PPI for life, besides his duration and thus the potential hardness for the patient, presents long-term complications recently described. Effects on the appearance of gastric precancerous lesion is not certain, but this association with an osteoporosis is more proved true. The PPI could also be a etiologic factor of chronic renal insufficiency and insanity. An endoscopic treatment describes by Inoue " Anti-Reflux Mucosectomy " ( ARMS) allows to decrease the gastro- esophageal reflux disease. This treatment is an equivalent of on treatment of the line Z which would at the same time allow to make sure of the decrease of recurrence on the line Z by complete treatment of this one and to handle the reflux of these patients. In this experimental series, 10 patients having made this endoscopic treatment were able to stop their treatment by PPI. The purpose of this study will be to make sure of the efficiency of the endoscopic treatment of the reflux by it on treatment of this line Z while decreasing the frequent recurrences on this line Z.
This randomized phase II trial includes a blood stem cell transplant from an unrelated donor to treat blood cancer. The treatment also includes chemotherapy drugs, but in lower doses than conventional (standard) stem cell transplants. The researchers will compare two different drug combinations used to reduce the risk of a common but serious complication called "graft versus host disease" (GVHD) following the transplant. Two drugs, cyclosporine (CSP) and sirolimus (SIR), will be combined with either mycophenolate mofetil (MMF) or post-transplant cyclophosphamide (PTCy). This part of the transplant procedure is the main research focus of the study.
The primarily goal of the research is to better understand progression of disease in patients who present with an acute stroke to the Hamad General Hospital (HGH) stroke and Transient Ischemic Attack (TIA) clinic. The investigators are specifically interested in patients who have diabetes and have a stroke. The patients enrolled into the research will have detailed clinical evaluation and their imaging studies (MRI and Doppler) will be reviewed. After informed consent, subjects will be examined in the stroke Ward /TIA clinic upon recruitment, and later at less than 48 hours of recruitment (blood extraction and urine samples) and for follow up visits at 1 month+/-7 days (clinical evaluation and to extract blood and urine samples), at 3 months (telephonic conversation only) and at 1 year (clinical and repeat MRI brain). During the initial visit at the ward the investigators will collect serum and plasma for proteomic and metabolomic studies. These will be repeated at less than 48 hours and at 1 month+/-7 days. Investigators will test the effects of risk factors such as diabetes/stroke on the endothelial procoagulant and inflammatory state at onset and evaluate if best medical control leads to improvement in such markers.The repeated studies will determine if better management and presence of certain blood biomarkers can predict or translate to slower progression of disease and correlate it with clinical status.
This phase I trial studies the best dose and side effects of CD19/CD22 chimeric antigen receptor (CAR) T cells when given together with chemotherapy, and to see how well they work in treating children or young adults with CD19 positive B acute lymphoblastic leukemia that has come back or does not respond to treatment. A CAR is a genetically-engineered receptor made so that immune cells (T cells) can attack cancer cells by recognizing and responding to the CD19/CD22 proteins. These proteins are commonly found on B acute lymphoblastic leukemia. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving CD19/CD22-CAR T cells and chemotherapy may work better in treating children or young adults with B acute lymphoblastic leukemia.
The investigators have previously shown the absence of toxicity of Treg-depleted-DLI and the possibility to triggering alloreactivity (GVHD/GVT) in relapsing patients dealing with hematological malignancies who had never shown any signs of GVHD after transplant or after one or more DLI. The Investigators, we plan to demonstrate the benefit of Treg-depleted DLI as compared to the reference treatment of relapse in hematological malignancies after allogeneic HSCT which is currently based on standard DLI
This clinical trial is designed to evaluate the role of lymph node dissection in the prevention of recurrence and metastasis after radical nephroureterectomy for high-risk primary upper tract urothelial carcinoma (UTUC) patients.
The ablation of atrial fibrillation (FA) by disconnection of pulmonary veins is a burgeoning intervention. It allows a long-term treatment of this arrhythmia with a success rate of about 80%. There are, nevertheless, some recidivism. Risk factors for recidivism are poorly codified and need further research. Indeed the identification of factors of poor prognosis could lead to not propose this procedure to the patients who present them and at least to inform them of an increased risk of failure. To date, aortic stiffness has not been studied in the context of assessing the risk factors for FA recurrence after ablation. On a physiopathological level, the aortic stiffness leads to increase left ventricle's post-load. Cardiac remodeling was observed with diastolic dysfunction and increased left atrial size. That may constitute a substrate for FA recurrence. In the literature, aortic stiffness can be measured in several ways: 1. Measurement of systolo-diastolic variation of the inner diameter of the aorta by scanner or transesophageal Echography (ETO). 2. Measuring of the Pulse Wave Velocity. 3. Measurement of aortic calcifications. The investigators propose to evaluate the impact of aortic stiffness on the recidivism of FA 6 months after ablation procedure performed in the Croix-Rousse cardiology's department.
This phase II Pediatric MATCH trial studies how well ensartinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with ALK or ROS1 genomic alterations that have come back (recurrent) or does not respond to treatment (refractory) and may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Ensartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The investigators evaluated the efficacy of a single early intravesical instillation of doxetaxel in the prevention of bladder recurrence after nephroureterectomy or distal ureterectomy for upper urinary tract urothelial carcinoma (UUT-UC).
