Frequency of FISH aberrations in RT patients. A The frequency of FISH aberrations in whole RT population. B The frequency of FISH aberrations in paired CLL and RT populations. Orange bars represent the frequency of FISH aberrations present in RT and absent in paired CLL, which reflect the evolution of genetic lesions during transformation. Blue bars represent the frequency of FISH aberrations present in RT and present in paired CLL, which reflect the maintaining of lesions during transformation. n—according to the availability of material, variable numbers reflect varying numbers of examined cases
