Active clinical trials for "Leukemia"

The aim of this study is to look for predisposing mutations in patients and relatives affected by AML and MDS with familial history of myeloid or, less frequently, lymphoid malignancies. Taking advantage of a next generation sequencing (NGS) platform, screening for known and unknown mutations potentially associated with the disease will be done. The screening will be performed on affected and unaffected family members, in order to outline new pedigrees that either validate previous findings or constitute novel discoveries.

The GMALL registry serves the purpose of ALL research and quality assurance. The Registry collects data about diagnostics, treatment and outcome of Adult ALL Patients in the clinical routine, whether or not the patient is treated within a clinical trial.

Database of Institut Paoli-Calmettes patients diagnosed with chronic lymphatic leukemia

Observational study aimed at evaluating the incidence of familial AML/MDSs in patients with de novo MDSs or AML with almost one relative affected by hematologic neoplasms and/or other cancers at young age (< 40 years)

Prolymphocytic leukemia T is a rare disease representing approximately 2% of mature lymphoid leukemias and 20% of prolymphocytic leukemias. It mainly affects the elderly with an aggressive clinical course. It is a hemopathy exhibiting a post thymic T phenotype (Tdt-, CD1a-, CD5 +, CD2 + and CD7 +), generally CD4 + / CD8-, but also CD4 + / CD8 + or CD8 + / CD4-. The main feature of T-PLL is the rearrangement of chromosome 14 involving genes encoding the T cell receptor complex (TCR) subunits, leading to overexpression of the proto-oncogene TCL1. On the molecular level, the study of Prolymphocytic leukemia T shows a substantial mutational activation of the IL2RG-JAK1-JAK3-STAT5B axis. Patients with Prolymphocytic leukemia T have a poor prognosis, due to a poor response to conventional chemotherapy. Treatment with the anti-CD52 monoclonal antibody: alemtuzumab has considerably improved the results, but the responses to treatment are transient; therefore, patients who obtain a response to alemtuzumab treatment are candidates for stem cell allograft (TSS) if they are eligible for this procedure. This combined approach extended the median survival to four years or more. However, new approaches using well-tolerated therapies that target signaling and survival pathways are necessary for most patients who are unable to receive intensive chemotherapy, such as JAK STAT axis inhibitors, anti-AKT, or anti BCL2 . Main objective: Better manage prolymphocytic T leukemias. Secondary objectives: Molecular characterization of prolymphocytic leukemia T. Study of the response to treatment, disease-free survival, overall survival. Impact of prognostic factors on response to treatment, and survival.

During the last decades hematologists have excelled at improving and refining the classification, diagnosis, and thus ultimately the therapeutic decision-making process for their patients. This continuous evolution proceeded in parallel to seminal discoveries in basic science such as FISH, PCR and NGS. So far, the current WHO classification serves as reference to diagnostic decision making and is largely based on 5 diagnostic pillars: cytomorphology of peripheral blood and/or bone marrow smears, histology and immunohistochemistry of bone marrow trephine biopsies or lymph nodes, immunophenotyping, chromosome banding analysis supplemented by FISH analysis, molecular genetics including PCR and targeted panel sequencing via NGS. This leads to a swift diagnosis in 90 % of all cases. The leftover 10 % remain a challenge for hematopathologists and clinicians alike and are resolved through interdisciplinary teams in the context of specialized boards. With the advent of high throughput sequencing (mainly WGS and WTS) the possibility of a comprehensive and detailed portrait of the genetic alterations - specifically in challenging cases - has become a realistic alternative to classical methods. In SIRIUS the investigators will prospectively challenge this hypothesis to address the question of how often a better or final diagnosis can be delivered by WGS and/or WTS and if unclear cases can be efficiently resolved.

The purpose of this registry study is to create a database-a collection of information-for better understanding T-cell lymphoma. Researchers will use the information from this database to learn more about how to improve outcomes for people with T-cell lymphoma.

A retrospective study using a new technology will be performed: the Optical Genome Mapping (OGM) on acute myelogenous leukemia (AML) samples stored at the CRB-Cancer of the Bordeaux University Hospital and annotated in the DATAML clinical database. The main objective is to estimate the proportion of AML patients for whom OGM detects at least one additional abnormality compared to conventional techniques. This study will constitute an important step in the validation of COA as a reference technique for cytogenetic analysis in AML, replacing the classical techniques, and could also constitute a first argument for redesigning the prognostic classification of AML.

This is a multicenter, observational real world clinical trial with prospective follow up that will evaluate the treatment outcome of adolescent and young patients with ph-negative acute lymphoblastic leukemia with first-line pediatric-like protocol in Argentina.

The investigators are doing this research study to assess the percentage of patients receiving stem cell transplantation for the type of blood cancer you have. They want to know how many patients get a transplant and why some patients do get a transplant while others do not. Also they want to explore why some patients elect not to undergo stem cell transplantation, when it is recommended by their physicians.
