Los tumores malignos en pediatría representan sólo el 2% de los casos de cáncer, sin embargo, las neoplasias son en la actualidad la segunda causa de muerte en niños mayores de 1 año de edad. Cada año se diagnostican aproximadamente 130 nuevos casos de cáncer por millón de niños. La leucemia es el más frecuente de los cánceres pediátricos, seguidos por tumores de cerebro, linfomas, neuroblastomas, sarcomas, tumores de Wilms y tumor de células germinales. La probabilidad de sobrevivir a una enfermedad maligna ha mejorado desde que en 1950 se reportaron las primeras remisiones en leucemia linfocítica aguda. Actualmente, debido al desarrollo de la quimioterapia, mejora en los métodos diagnósticos y el manejo multidisciplinario de los pacientes, el porcentaje de curación es cercano a un 75%. A pesar de estos avances, es aún necesario una mejoría de los resultados en el cáncer pediátrico, que depende del diagnóstico temprano de la enfermedad.

Organ donation in Chile is insufficient, with a historical rate of six donors per million inhabitants. Legal reforms, organizational improvements, and communications campaigns have made 2019 the most successful year in terms of organ donations and transplants. The first liver transplant in Chile was performed in 1969 at the Naval Hospital in Valparaíso. However, the patient passed away shortly after. The first successful transplant was performed in 1985 at the Militar Hospital in Santiago. As of that date to present day, 1.812 liver transplants have been performed: 43.6% of these in university hospitals, 35.1% in private clinics, and 21.5% in state hospitals. Of these, 23.1% were performed at the Pontificia Universidad Católica de Chile (PUC), 20.6% at the Universidad de Chile Clinical Hospital (HCUCH), 15.9% at the Luis Calvo Mackenna Hospital (HLCM), 15.9% at the Las Condes Clinic (CLC), 14.3% at the Alemana Clinic in Santiago (CA), 5.6% at the del Salvador Hospital (HdS), 2% at the Dávila Clinic (CD), 2% at the Alemán Sanatorium in Concepción (SA), and 0.9% at the Santa María Clinic (CSM). Of this total, 455 correspond to pediatric patients. Of these patients, 63.3% were at the Luis Calvo Mackenna Hospital, 21.1% at the Las Condes Clinic, 7.7% at the Pontificia Universidad Católica de Chile, 6.4% at the Alemana Clinic, and 1.5% at the Alemán Sanatorium. Since 2015, approximately 80% of pediatric transplants are performed at the HLCM. Reported one-year survival range from 75% to 85% in adults and 75% to 92% in pediatric patients per year, depending on the period. Some centers have never reported their results. It is expected that education of a society prone to organ donation improves, as well as improving the detection, maintenance, and procurement of potential donors, increasing the utilization of organs, enhancing the utilization of organs from deceased donors with Split technique, and, while we are building towards a donation system that responds to the needs of the nation, upholding live donor programs. Finally, younger generations are to be motivated so that they dedicate themselves to this important activity. [ABSTRACT FROM AUTHOR]
