FIGURE 5.2 FISH results for HER2 (a and b) and ALK (c and d). (a) Control with normal

cells (arrows) with two copies of centromere signals (green) and two copies of HER2 signals

(red) for chromosome 17; (b) a patient with abnormal cells (arrows), two copies of centromere

signals (green), and amplified HER2 signals (red). (c) LSI ALK Dual Color Break Apart

probe (Abbott Molecular; www.abbottmolecular.com). (d) FISH results for ALK rearrangement.

Arrow: abnormal cells with one fusion signal, separate one red and one green signal

indicating ALK rearrangement.
