Active clinical trials for "Leukemia"

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. It may also help doctors predict how patients respond to treatment. PURPOSE: This research trial studies DNA in samples from patients with acute myeloid leukemia.

RATIONALE: Studying samples of bone marrow from patients with cancer in the laboratory may help doctors predict how well patients will respond to treatment. PURPOSE: This research trial is studying biomarkers in predicting response to treatment in bone marrow samples from young patients with acute myeloid leukemia.

RATIONALE: Studying samples of bone marrow and blood from patients with cancer in the laboratory may help doctors predict how well patients will respond to treatment. PURPOSE: This research study is studying biomarkers in bone marrow and blood samples from older patients with acute myeloid leukemia treated with cytarabine-based therapy.

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

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

RATIONALE: Studying samples of DNA in the laboratory from patients who received fludarabine-based treatment may help doctors learn more about the effects of fludarabine on cells. It may also help doctors understand how well patients respond to treatment. PURPOSE: This research study is studying DNA samples from patients with chronic lymphocytic leukemia previously treated with fludarabine-based therapy.

Acute lymphoblastic leukemia (ALL) accounts for about 20% of adult leukemias. Treatment results in adult ALL have lagged behind the improvements achieved in the pediatric population. A modified version of the Dana Farber Cancer Institute pediatric protocol is used to treat adult patients with ALL. The results seem to be superior to those reported with other adult protocols. However, there is limited data on the impact of such intensified approaches and resulting toxicities on the quality of life (QOL) of these survivors. Identifying important factors affecting the QOL may permit attempts at early interventions and may help to further modify the regimen and mitigate these adverse effects on QOL. This study is evaluating the quality of life of long term survivors of adult ALL. It involves the patients filling out several questionnaires that are well-validated measures assessing various QOL issues of concern to these patients. The following questionnaires are used in this study: EORTC QLQ C30 to assess global health and major health domains Brief Pain Inventory (BPI) Personal Health Questionnaire (PHQ9) to assess psychosocial distress Functional Assessment of Cancer Therapy (FACT) Fatigue Questionnaire Peripheral Neuropathy Questionnaire The data obtained from the questionnaires will be analyzed and the various domains of health will be quantified.
