Filter by:Adoptive immunotherapy using CAR-T cells is now one of the Advanced Therapy Medicines routinely used for relapsed or refractory lymphoid hemopathies. In 2023, in France, 5 types of CAR-T cells have marketing authorization for 6 different indications. However, these marketing authorizations are based on clinical trials involving a limited number of selected patients. Real-life data are essential for assessing the post-authorization use of these innovative treatments. The French national DESCAR-T registry, promoted by LYSARC and in which Toulouse University Hospital plays an active role, is an international reference for this real-life evaluation. It does not, however, allow precise evaluation of patient-centered indicators and care pathways. With the increasing number of indications and candidate patients, Toulouse University Hospital, the only healthcare facility authorized in the Western Occitanie region to administer CAR-T cells, is faced with growing hospital needs and longer treatment times. In 2023, this has necessitated the implementation of new ambulatory and inter-facility care pathways in collaboration with the referral centers of the Onco-Occitanie Ouest regional cancer network. The selection of patients for CAR-T cell treatment is based on objective clinical criteria linked to the pathology (histology, morphological localization, size and kinetics of the tumor mass) and the patient (physiological age, performance index, comorbidities, patient choice). Because of their innovative nature, in a difficult psychological and physical context for the patient (refractory disease), CAR-T cell care pathways also need to be evaluated in terms of their "quality of life" dimension. The impact of non-biological determinants (also described as social and territorial inequalities in health) such as place of residence and distance from healthcare provision, marital, economic and social status, has never been explored on the accessibility and progress of the CAR-T cell treatment pathway. The creation of a registry of patients eligible for CAR-T cells at Toulouse University Hospital will enable these lines of research to be explored on the scale of a region with a population of 3 million.
To look for the replication of HHV6 by PCR in the skin, in these patients with haemopathies presenting an exanthema. This will make it possible to evaluate the prevalence of the positivity of this PCR in the skin. Then the investigator can investigate whether there is an association between the positivity of HHV6 PCR in the blood and / or skin and the viral etiology of the exanthema. If this association exists, it will make it possible to improve the diagnosis in the context of the exanthema and thus to improve the therapeutic management of these patients.
This study is a proof of concept that will assess the Predictor's kit performances. The test will be performed by several technicians, in immunological laboratories of several sites in France. In this study, "couples" of donor / recipient in the frame of a graft of CSH will be included.
Recent advances in hematology clearly illustrate that the simple "clonal" nature of various hematological malignancies may not really reflect the reality of malignant cells natural expansion. This has been nicely illustrated in recent works in AML for example where subclones coexists in the same patient at the same time, but could also differentially expand over time because of effects of therapeutics intervention, but also by oncogenic spontaneous events (1). These observations have been done recently because of next generation sequencing that allows to discriminate in the same tumor samples, different subclones and to analyse the clonal architecture. Sequential analyses could help us to identify the first oncogenic event and to correlate disease progression to the emergence of subclones. For all these reasons it is of a major interest to precisely understand the architecture of the clone in MPNs, especially to understand which is the initiating event and how from this initial event the clone develops. In MPNs in which JAK2V617F is the initiating event, its targeting is expected to be extremely effective. If JAK2V617F is a secondary event its targeting might allow to alleviate the MPN, but may favor the development of other malignant hemopathies.
The aim of this open, controlled, multicentre biomedical research study is to identify new markers specifically associated with Horton's disease. This would make it possible to improve the diagnosis and management of this disease. Participation consists in taking one or several blood samples depending on the group patients/controls.
