Abstract: There is an error in the second sentence of the "Classification of cancers" sub-heading under the "Patients and Methods" section. The correct sentence for this section is: "We further arranged the cancers into 4 subgroups (leukaemia, lymphoma, CNS tumours, all other solid tumours) based upon the International Classification of Childhood Cancer (ICD-10) system [18], corresponding respectively to its diagnostic groups I, II, III and IV-XII, as used in previous studies [11]."
