Is it possible to have 50 chromosomes?

These findings show that initial hyperdiploidy (greater than 50 chromosomes) is an independent favorable prognostic sign in childhood ALL and additional chromosomal structural abnormalities may not indicate a poor prognosis among childhood ALL with hyperdiploidy (greater than 50 chromosomes).
