The third edition of the DiR-Guàrdia Urbana race raised 3,500 euros for research in child cancer at Vall d’Hebron Institute of Research (VHIR). Nearly 8,000 people ran the entire Diagonal of Barcelona with two messages: “for you maybe is just a race, but for them is their life” and “run and help us to investigate for children with cancer”. The donation will fund the research carried out by the group headed by Dr. Josep Sánchez de Toledo, who after the race thanked the participants for their support and said that “if research stops, the world stops”.The 10km race was organized by VHIR with the collaboration of the Guàrdia Urbana and the Barcelona city council to promote exercise and healthy habits and to support a solidarity cause. In this case, they decided to support the research group led by Dr. Sánchez de Toledo, whose mission is to improve the diagnosis and treatments available for cancer during childhood. Each year in Spain nearly 1,000 children are diagnosed with child cancer and the survival rate is in the 80%.The Translational Research in Child and Adolescent Cancer group works closely with the Oncohematology Service at Vall d’Hebron University Hospital that is a reference international center in the treatment of cancer and hematologic diseases during childhood. Thanks to their experience, human resources and technological equipment, they offer a multidisciplinary attention to patients and relatives, covering all the diagnostic procedures and the most advanced treatments.
