Moreover, mutations in genes such as ABL proto-oncogene 1 (ABL1), BUB1 mitotic checkpoint serine/threonine kinase B (BUB1B), nuclear receptor corepressor 1 (NCOR1), chimeric antigen receptors (CARS), heat shock protein 90 alpha family class B member 1 (HSP90AB1), and nuclear receptor coactivator 1 (NCOA1) have been found only in recurrent diseases [11,41]. This evidence concerns the gene HSP90AB1 and disease recurrence.
