Overall survival comparison of CML patients with simple chromosomal abnormalities (SCAs, n = 15) vs. complex chromosomal abnormalities (CCAs) (n = 23) according to a correlation of both chromosomal analysis and FISH test results. The mean survival/follow-up lengths were 102 months (range 12–242 months) in the SCAs group and 75 months (range 11–201 months) in the CCAs group respectively. A statistically significant difference for overall survival was observed between these two groups (p = 0.004).
