Active clinical trials for "Leukemia"

RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about cancer and the development of drug resistance in patients. It may also help doctors find better ways to treat cancer. PURPOSE: This research trial is studying samples from patients with leukemia.

The purpose of this post-marketing surveillance is to investigate and confirm the type and incidence of newly identified adverse events and any other factors affecting safety and efficacy of Sprycel® so that the regulatory authority can manage the marketing approval properly.

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

The purpose of the study is to determine the utility of XCL1 in the prognosis of acute lymphoblastic leukemia.

This clinical trial is studying biomarkers as a diagnostic tool in samples from younger patients with B-cell acute lymphoblastic leukemia. Finding specific biomarkers may help improve the treatment of patients with B-cell acute lymphoblastic leukemia

Chronic myeloid leukemia is a serious disease which is characterized by progression from relatively quiescent stages of the disease to an aggressive phase. Although now there is highly successful medical therapy known as Gleevec (Imatinib), the treatment is not always successful and patients do develop resistance. Those patients have limited treatment options. We are developing a gene therapy model of treatment for this disease using pseudoviral particles to insert molecules of genetic material which would not allow the harmful genes causing the leukemia to function.

RATIONALE: Questionnaires that measure quality-of-life may improve the health care team's ability to plan supportive care for patients undergoing donor bone marrow transplantation. PURPOSE: This clinical trial is studying quality of life in patients who are undergoing donor bone marrow transplantation.

RATIONALE: Studying samples of 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 biomarker expression in bone marrow samples from patients with acute myeloid leukemia.

RATIONALE: Studying bone marrow and blood samples from patients with leukemia or lymphoma treated with arsenic trioxide may help doctors learn more about cancer. PURPOSE: This research study is assessing arsenic trioxide in young patients with recurrent or refractory leukemia or lymphoma who were treated on clinical trial NCI-00-C-0070J.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about cancer and the development of drug resistance in patients. PURPOSE: This laboratory study is looking at resistance to methotrexate in patients with acute lymphoblastic leukemia in relapse or remission.
