Active clinical trials for "Leukemia"

RATIONALE: Studying blood samples from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research trial studies biomarkers related to chemotherapy resistance and outcomes in samples from older patients with acute myeloid leukemia.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in samples from young patients with acute myeloid leukemia.

Asparaginase is an important drug in the treatment of childhood leukemia. One of the rare but severe side effects to the treatment is thrombosis in or outside the central nervous system. The aim of this study is to investigate and describe the influence on the coagulation parameters during prolonged treatment with asparaginase. Hopefully this knowledge will help to foresee the risk of thrombosis and thus making it possible to prevent these.

RATIONALE: Studying samples of blood or tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in samples from patients with Down syndrome and acute megakaryoblastic leukemia.

RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying blood and tumor tissue samples from young patients with acute myeloid leukemia.

RATIONALE: Studying samples of blood or tumor tissue from patients with cancer in the laboratory may help doctors learn about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarker changes in samples from young patients with acute myeloid leukemia.

The purpose of this study is to determine if MultiStem® can safely be given to patients with acute leukemia, chronic myeloid leukemia, or myelodysplasia after they have received hematopoietic stem cell transplantation.

Treatment of acute lymphoblastic leukemia achieves high cure rate, but is potentially neurotoxic. Long-term neurologic morbidity in survivors and its effect on function are inadequately studied. Neurologic outcomes will be assessed through an investigator administered questionnaire followed by comprehensive neurologic examination by the study neurologist.

RATIONALE: Studying samples of blood and bone marrow from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood and bone marrow samples from patients with previously untreated primary acute myeloid leukemia.

RATIONALE: Collecting and storing samples of bone marrow and blood from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at lymphoblasts in young patients with high-risk acute lymphoblastic leukemia.
