Tumors which harbored a few unclassifiable genomic anomalies in the Lastowska's classification consisted in genotype “flat” or “atypical”, in contrast to those fitting with genotypes 1, 2 and 3 criteria. Symbols are related to DNA index value (DI): ○, hyperdiploid; ●, diploid; ▪, tetraploid. × means that DI value was not determined. nd: not done. Tumors #: 1–12, 4S; 13–20, [1yr−]; 21–29, [1yr+].
