It should be noted that, like in our study, it is probable that this finding could be related to a relevant difference in disease stage at the moment of allo-HCT between the two groups (total BC + AP + CP2 + CP3 in 47.2% for IMA vs. 8.6% TKI-naïve, p = 0.001) [43]. This evidence concerns the gene DHCR7-DT and breast cancer.
