The "Sin Piedad contra el Cáncer" initiative has donated €15,080 to the Sarcoma Laboratory of the Childhood Cancer and Blood Diseases group at the Vall d'Hebron Research Institute (VHIR). "Sin Piedad!", is a battle cry that ended up becoming a ritual and a combative spirit for a family from Malaga when their son was diagnosed with paediatric cancer. A symbol represented by a fist and materialised in T-shirts that have become the "uniform" with which David and his family always go to the hospital, joining their fists together to the united cry of "Sin Piedad!" They shared their story through their Instagram account: @sinpiedadcontraelcancer and sparked the solidarity and empathy of thousands of people who wanted to join David's fight by buying T-shirts and sending videos to the Instagram account, joining in the cry of "Sin Piedad contra el cáncer". Thus, virtually spontaneously, an initiative was born that has raised funds for the fight against cancer.

The €15,080 will go to the project "Development of new therapies for childhood sarcomas". Sarcomas are a very diverse type of malignant connective tissue tumour formed by the proliferation of mesoderm cells that can originate in a wide variety of tissues. VHIR is studying several specific molecular targets present in these cancers. All of them are essential proteins for tumour development, whose pharmacological blockade can lead to the paralysis of tumour growth. Dr. Josep Roma, head of the Sarcoma Laboratory at VHIR, explains that "the ultimate goal of the project is to increase the pharmacological arsenal available to fight this disease, especially in cases that do not respond to conventional therapy".
