Leukaemia is the most common cancer in childhood. It occurs when white blood cells transform into malignant or cancerous cells. Among the types of childhood leukaemia we treat are the following:

  • Acute lymphoblastic leukaemia (ALL)
  • Acute myeloid leukaemia (AML)
  • Other uncommon leukaemias such as chronic myeloid leukaemia (CML) and juvenile myelomonocytic leukaemia (LMMJ)

Treatment of leukaemia in Spain

SJD Barcelona Children's Hospital belongs to Innovative Therapies for Children with Cancer (ITCC), which allows us to access the most innovative treatments and include our patients in pioneering clinical trials. An example of new treatments is the application of CAR-T 19 immunotherapy: we are one of the few pediatric centers in Europe and the only one in Spain that offers this therapy. 

Currently, CAR-T 19 immunotherapy treatment is offered in patients who have undergone conventional treatments without success, usually with one or more relapses.


The SJD Barcelona Children's Hospital investigates the main types of childhood leukaemia that affect our patients. The objective of our research groups on pediatric leukaemia is to deepen our knowledge of the origin and molecular basis of this type of cancer to achieve new tools for diagnosis, prognosis and treatment.
