Implication

Case series reports severe therapy-resistant acute non-lymphocytic leukemia in patients receiving prolonged chemotherapy, highlighting the need for careful surveillance and treatment optimization.

Key Points

To evaluate the clinical features, chromosomal abnormalities, and survival outcomes of secondary acute non-lymphocytic leukemia arising after long-term chemotherapy.
Analyzed clinical records of 20 patients who developed acute non-lymphocytic leukemia after chemotherapy for primary hematologic malignancies, solid tumors, or rheumatoid arthritis.
Evaluated chemotherapy duration, pre-leukemic cytopenias, karyotypes from chromosome analyses (N=15), treatment response, and autopsy pathology.
Secondary leukemia developed between 11 and 132 months (mean approximately 60 months) after starting chemotherapy, with pre-leukemic cytopenias present in 15 of 20 patients.
Chromosome abnormalities occurred in 14 of 15 tested patients, and the disease was universally refractory to chemotherapy, resulting in a median survival of only 2 months.
