Since the publication of the above paper, the authors have detected a minor error that has no impact on the conclusion.

Please note that the second sentence of the third paragraph ‘Flowcytometric analysis of the primary ALL showed common ALL phenotype with aberrant expression of CD66c, the myeloid marker CD13 and the progenitor marker CD117.’ should be corrected to ‘Flowcytometric analysis of the primary ALL showed common ALL phenotype with aberrant expression of CD66c and hyperdiploid DNA content (DNA index 1.17).’

The authors apologize for any inconvenience caused.
