All of Spain's specialist centers for childhood cancer have joined together in a network to combat leukemia relapses in children.

All specialized pediatric cancer centers across Spain have united to form a collaborative network known as the 'Red de Leucemia Linfoblástica Aguda Recidivante' (ReALLNet). This newly established organizational system is designed to coordinate joint medical responses and actions when children experience relapses of acute lymphoblastic leukemia.

The initiative brings together hospitals nationwide that treat childhood cancer to improve clinical coordination and management of recurrent cases. By standardizing cooperation through this specialized network, the institutions aim to address the complex challenges associated with leukemia relapses in pediatric patients.
