Although the evaluation of the status of chromosome 2 was performed in only a small proportion of the IBC tumors, the finding of aneusomy for chromosome 2 in majority of the tested IBC patients (7/8) suggests that the finding of mildly increased copy numbers of the ALK gene by FISH resulted mostly from mildly increased copies of chromosome 2 and not due to ALK gene amplification. Here, ALK is linked to inflammatory breast carcinoma.
