FR901228 in Treating Patients With Myelodysplastic Syndrome, Acute Myeloid Leukemia, or Non-Hodgkin's Lymphoma

DISEASE CHARACTERISTICS:

• One of the following diagnoses:
• Histologically confirmed refractory or relapsed acute myeloid leukemia (AML)
• Failed anthracycline-based chemotherapy
• Ineligible for or refused allogeneic stem cell transplantation
• Elderly patients with newly diagnosed AML
• Ineligible for or refused standard chemotherapy
• Histologically confirmed high-risk myelodysplastic syndromes
• Eligible subtypes include:
• Refractory anemia with excess blasts (RAEB)
• RAEB in transformation
• Chronic myelomonocytic leukemia
• Ineligible for or refused allogeneic bone marrow transplantation
• Histologically confirmed intermediate-grade non-Hodgkin's lymphoma (NHL)
• Relapsed after high-dose therapy OR
• Ineligible for allogeneic or autologous stem cell transplantation
• Evaluable lesions by radiologic study or physical examination
• Histologically confirmed follicular NHL
• Progressed after anthracycline-based chemotherapy and rituximab
• Evaluable lesions by radiologic study or physical examination NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
