Active clinical trials for "Leukemia"

The purpose of this study is to investigate the efficacy and safety for treating adult ALL patients with the pediatric protocol.

This research study measures the safety and efficacy of the combination of three drugs that are approved, Nipent, Rituxan and Cytoxan in the treatment of Chronic Lymphocytic Leukemia (CLL). These drugs are being given together for investigational purposes as the specific combination of these three drugs has not been approved for treatment of CLL by the FDA.

RATIONALE: Decitabine may help myelodysplasia cells develop into normal stem cells. It is not yet known if decitabine is more effective than standard supportive care in treating myelodysplastic syndrome. PURPOSE: Randomized phase III trial to compare the effectiveness of low-dose decitabine with that of standard supportive care in treating older patients who have myelodysplastic syndrome.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of liposomal cytarabine in treating young patients who have recurrent or refractory meningeal leukemia, lymphoma, or solid tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating older patients with acute myeloid leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of two different combination chemotherapy regimens in treating older patients with acute myeloid leukemia in first remission.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of various combination chemotherapy regimens or bone marrow transplantation in treating patients with chronic myelogenous leukemia.

Due to progressive therapy intensification in the four consecutive studies AML-BFM 78, 83, 93 and 98, prognosis for children with acute myeloid leukemia (AML) has improved steadily. In spite of the intensified therapy, rates of morbidity and mortality have remained unchanged or have even decreased. Against the background that about 40% of the patients still die from immediate causes of an underlying disease relapse or of nonresponse, it seems to be justifiable to intensify therapy - especially for high-risk patients - which on its parts will require an optimization of supportive measures. As the present risk stratification into standard- (SR) and high-risk (HR) patients has proved effective, we will pursue the risk-adapted therapy strategy. The aim of the study is to improve prognosis in children with AML by intensification of cytostatic therapy and to evaluate by randomisation the equivalence of a prophylactic central nervous system (CNS) irradiation with a total dose of 18 Gy versus 12 Gy.

RATIONALE: Biological therapies such as denileukin diftitox may be able to deliver cancer-killing substances directly to non-Hodgkin's lymphoma cells. PURPOSE: Phase II trial to study the effectiveness of denileukin diftitox in treating patients who have non-Hodgkin's lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy to kill tumor cells. It is not yet known which regimen of combination chemotherapy with or without bone marrow transplantation is more effective in treating promyelocytic leukemia PURPOSE: Randomized phase III trial to compare the effectiveness of different combination chemotherapy regimens with or without bone marrow transplantation in treating patients who have promyelocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Randomized phase II trial to study the effectiveness of various combination chemotherapy regimens in treating patients with acute lymphocytic leukemia.
