Overall survival comparison of CML patients with BCR–ABL1 fusion located on der(22) (n = 26) vs. non-der(22) (n = 12, including chr. 9, n = 11 and chr. 19). The mean survival/follow-up lengths were 75.6 months (range 11–242 months) in the der(22) group and 107 months (range 12–201 months) in the non-der(22) group respectively. No statistically significant difference for overall survival was observed between these two groups (p = 0.41).
