This prospective randomized trial was extension to the previous controlled prospective study performed in Children's Cancer Hospital, Egypt and registered at clinicaltrials.com (NCT01635140). The ultimate aim of this work is to demonstrate noninferiority of the hypofractionated regimens relative to the conventional regimen in a controlled randomized clinical study.
