Active clinical trials for "Leukemia"

This study will use genomics-based technology, such as DNA microarrays, to more precisely diagnose subsets of lymphoma, leukemia and multiple myeloma patients. There have been many attempts to classify lymphoid cancers in ways that will be useful for clinical diagnosis and treatment. Although broad diagnostic categories have been reliably defined, patients within each category have distinct clinical courses, suggesting that these classifications could be further divided into molecular (genetic) subtypes. For example, 40 percent of patients with diffuse large B-cell lymphoma achieve long-term disease remissions following combination chemotherapy and are apparently cured, whereas the remaining 60 percent die from the disease. Similarly, some patients with follicular lymphoma develop aggressive disease within a few years of diagnosis, while others have stable disease over 10 to 20 years. Although the distinctions in clinical course of these diseases are recognized, there are no studies to determine the molecular (genetic) basis for this variability. This study will try to define new molecular diagnostic categories in these diseases and correlate them with clinical features, including treatment response, disease remission and overall survival following chemotherapy. This retrospective study will use clinical data and tissue samples from participating centers in the Lymphoma/Leukemia Molecular Profiling Project LLMPP). New patients will not be recruited for this study. Biopsy materials, including fresh frozen or OTC-embedded lymphoma biopsy material, viably frozen samples of peripheral blood cells from leukemia patients, and viably frozen samples of bone marrow aspirates from multiple myeloma patients will be collected from pathologists participating in the LLMPP. RNA and genomic DNA will be extracted from the tumor samples. A variety of technologies will be used to characterize the genome of the cancer cells, including lymphochip microarrays for array-based comparative genomic hybridization; Southern blotting and PCR for translocation of genes previously implicated in these malignancies; and PCR and DNA sequencing methods for analyzing base changes in the genome of the cancer cells. Clinical information from the initial diagnosis to disease relapse will be taken from existing databases and/or patient charts. Gene expression will be correlated with the clinical data. If a small number of genes is found to strongly predict clinical outcome, quantitative RT-PCR assays using the Taqman technology may be developed as an alternative to DNA microarray analysis.

The aim of this study is to examine the association of exposure to air contaminants (PAH & VOC) emitted from the petrochemical industries, specific genetic polymorphisms (P4501A1 (MspI & exon 7) and GSTM1 & T1) of study subjects and their parents, and the risks of brain tumors and leukemia among children and youths in metropolitan Kaohsiung, southern Taiwan.

This pilot research trial studies biomarkers in bone marrow samples from pediatric patients with high risk acute myeloid leukemia. Studying samples of bone marrow from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.

This research trial studies metabolic changes in blood samples from patients with acute myeloid leukemia. Studying samples of blood from patients with acute myeloid leukemia in the laboratory may help doctors learn more about cancer and the development of drug resistance.

Primary Objective: To estimate the incidence of treatment-emergent and treatment-related adverse events during treatment with blinatumomab in pediatric and adolescent subjects with B-precursor ALL in second or later bone marrow relapse, in any marrow relapse after alloHSCT, or refractory to other treatments Secondary Objective(s): To describe key efficacy outcomes, including incidence of complete response (CR) within 2 cycles of blinatumomab, minimal residual disease (MRD) remission within 2 cycles of blinatumomab, relapse free survival (RFS), overall survival (OS), incidence of alloHSCT, and 100-day mortality after alloHSCT. Hypotheses: A formal statistical hypothesis will not be tested. The incidence of treatment-emergent and treatment-related adverse events will be estimated. Study Endpoints: Incidence of treatment-emergent and treatment-related adverse events Incidence of CR within 2 cycles of blinatumomab MRD remission within 2 cycles of blinatumomab RFS OS Incidence of alloHSCT 100-day mortality after alloHSCT Study Design: Multi-center, open-label, single-arm expanded access protocol

This is a retrospective study to analyze the therapeutic results and clinical evolution all patients diagnosed with AML and aged ≥ 60años or not candidates for chemotherapy intensive, treated according to the different schemes available, including supportive care or palliative.

The purpose of this study is to examine the phenotypic and genotypic characteristics and their associations with symptom clusters experienced during treatment for childhood leukemia.

This study is a clinical study aiming at establishing immunological assays for the qualitative and quantitative evaluation of WT-1, Survivin and HPV16 E7-specific immune responses in cancer patients. Such a study will allow the development of suitable immunological tools to be used in assessing response in a subsequent phase I study aiming at evaluating therapeutic vaccine candidates targeting WT-1, Survivin and/or HPV16 E7-expressing tumors. In addition, this study will help defining the baseline cancer-associated immune responses in the selected patient population. Cervical and ovarian cancer patients, as well as leukemia patients, will be included in this study. WT-1, Survivin and HPV-specific immune responses will be monitored in these patients by ex vivo and cultured IFNg ELISpot as well as tetramer staining.

This protocol will allow expanded access of ponatinib to patients ≥18 years with chronic myeloid leukemia (CML) any phase or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ALL) who have failed all available treatment options.

Familial aggregation is well recognized in some cancers. Though a number of familial cancer predisposition syndromes have been described, the nature of inherited genetic alterations in patients with a strong history of familial cancer is currently unknown, as is the case with childhood acute lymphoblastic leukemia (ALL). The investigators are seeking to learn more about what causes leukemia and why some people and families may be at a higher risk of developing this disease. By understanding the origin of the disease, better treatments may be identified for patients with leukemia. PRIMARY OBJECTIVE: To identify variants in genes that are inherited, have altered gene structure and/or function, and influence the risk of developing acute lymphoblastic leukemia (ALL) and other cancers. SECONDARY OBJECTIVE: To collect demographic, clinical and laboratory information including detailed family cancer history and response of cancers to therapy for correlation with the primary objective.
