Vorinostat and Decitabine in Treating Patients With Advanced Solid Tumors or Relapsed or Refractory Non-Hodgkin's Lymphoma, Acute Myeloid Leukemia, Acute Lymphocytic Leukemia, or Chronic Myelogenous Leukemia

This phase I trial is studying the side effects and best dose of vorinostat when given together with decitabine in treating patients with advanced solid tumors or relapsed or refractory non-Hodgkin's lymphoma, acute myeloid leukemia, acute lymphocytic leukemia, or chronic myelogenous leukemia. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with decitabine may kill more cancer cells.
