A) Non-euploidy in human tumors, defined as any numerical deviation from a multiple of 23. Non-euploidy also includes pseudoeuploidy (i.e. 46, XY,−5,+9). B) Ploidy in human tumors, according to ISCN definitions. Multiple ploidy indicates a tumor with multiple clones from more than one ploidy level. C-D) CIN, defined as tumors having a range of chromosome numbers ≥ 2 (i.e. 47–49 chromosomes). C) ClN and chromosomally stable tumors classified by ploidy level. D) CIN by tumor site.
