OBJECTIVES: To explore the clinical significance of clonal evolution of additional chromosomal 8 in CML progression.
METHODS: An unusual case with the clonal evolution from trisomy 8 to tetrasomy 8 accompanied by 2 time of CML blast crisis (BC) was reported.
RESULTS: This patient suffered from 2 time of CML blast crisis and the additional chromosome 8 aberrations were accompanied. Trisomy 8 and tetrasomy 8 were detected at first CML blast crisis and second CML blast crisis, respectively. After tetrasomy 8 was developed, the c-Myc was over-expressed and the central nervous system leukemia happened in this case. Only high dose Ara-C and MTX regimen could induce remission for a short period.
CONCLUSION: These findings suggested that additional chromosome 8 aberrations are important marker for poor prognosis of CML patients and contribute to a poor prognosis.
