OBJECTIVE: To explore the relationship between cytogenetic and clinical features and prognosis for patients with acute monocytic leukemia (M5 type).
METHODS: Chromosome samples were prepared by direct culture of bone marrow for 24 hours. Karyotypes of 80 patients with M5 were analyzed by R banding. Rearrangement of MLL gene and deletion of P53 gene were detected by fluorescence in situ hybridization (FISH).
RESULTS: Forty-three patients (53.75%) were found to have abnormal karyotypes, which included 23 patients with abnormalities of chromosome 11 and 20 with other chromosomal abnormalities. Twenty-four patients had MLL gene rearrangements and 17 had P53 gene deletion.
CONCLUSION: 11q23 has been the most common chromosomal abnormality among patients with M5, which is associated with poor prognosis. The frequency of P53 gene deletion in patients with genetic abnormalities were significantly higher than those with normal karyotypes (P < 0.05).
