Column A indicates chromosome arms with copy number alterations in more than 15% of the first examined biopsies from all patients (n = 44). Chr 18 and X were the only ones with gain of the whole chromosome in more than 15% of the cases, and a whole chromosome gain was seen in 9 (21%) and 20 (46%) of the cases, respectively. Column B indicates chromosome bands with the highest frequency of gain or loss within the arm specified in column A. Column C indicates the number and frequency of cases harboring gain or loss in the region specified in column B.
