Summary
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide and gemtuzumab ozogamicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with gemtuzumab ozogamicin works in treating patients with advanced myelodysplastic syndromes.
Eligibility Criteria
DISEASE CHARACTERISTICS:
- Diagnosis of one of the following hematologic malignancies:
- Myelodysplastic syndromes (MDS) of one of the following French-American-British (FAB) classifications:

- Chronic myelomonocytic leukemia (CMML) with > 5% myeloblasts (WHO CMML-2)
- International Prognostic Scoring System (IPSS) score of intermediate-2 or higher in the setting of > 5% myeloblasts
- Acute myeloid leukemia that has evolved from MDS
- Must not be a candidate for bone marrow transplantation as first-line therapy or must have declined bone marrow transplantation
PATIENT CHARACTERISTICS:
- Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
- Life expectancy of at least 4 months
- Serum potassium ≥ 4.0 milliequivalent (mEq/dL) and serum magnesium ≥ 1.8 mg/dL (supplemental electrolytes allowed)
- Absolute corrected QT interval (QTc) interval 2.5 mg/dL
- serum glutamate oxaloacetate transaminase (SGOT) or serum glutamate pyruvate transaminase (SGPT) > 1.5 times upper limit of normal
