Fig. 2. Aneuploidy changes during relapse of lower grade astrocytoma, grade 4 astrocytoma and GB.
a Aneuploidy score for lower grade astrocytoma (n = 11) and their recurrence. b Aneuploidy score for grade 4 astrocytoma (n = 8) and their recurrence. c Aneuploidy score for GB (n = 46) and their recurrence. Points in light blue color represent primary samples, and in dark blue represent recurrent samples. d Boxplot of aneuploidy score for the primary and recurrent lower grade astrocytoma, grade 4 astrocytoma and GB. e Aneuploidy score difference (recurrent - primary) between primary and recurrent samples for lower grade astrocytoma, grade 4 astrocytoma and GB. For boxplots in (d) and (e), the upper and lower boundaries represent the first and third quantiles, respectively. The horizontal lines represent the median, and the whiskers denote the lowest and highest values except for outliers (black dots). Overall survival for primary lower grade astrocytoma (f), grade 4 astrocytoma (g) and GB patients (h) with small or large aneuploidy changes. Survival analysis was performed with the combination of our data (n = 49) and data downloaded from cBioPortal (n = 187). Cases with aneuploidy difference bigger than 3 or smaller than −3 was classified into large change group, others were classified into small change group. P values were obtained from the log-rank test.
