WHO Calls for Investment to Close Global Gaps in Childhood Cancer Survival

Each year approximately 400,000 people under the age of 19 are diagnosed with cancer worldwide globally. Although many childhood cancers are highly treatable, survival rates vary dramatically by location. In high‑income countries, five‑year survival now sits between 80 % and 90 %, while in countries with weaker health systems it hovers around 40 %. For lymphoid leukaemia, the median five‑year survival is about 66.7 % for children under 15, but drops to nearly 39 % for adolescents aged 15‑19. WHO has compiled comparable baseline data for 194 nations, creating the first standardized global picture of childhood cancer outcomes.

The report highlights that the Western Pacific and Europe have achieved some of the highest survival estimates, whereas Africa and parts of the Eastern Mediterranean continue to struggle. Persistent challenges include delayed diagnosis, limited access to essential medicines, and gaps in high‑quality care. Adolescents face an especially steep survival divide; they encounter different cancer types, often transition between paediatric and adult services, and suffer from a scarcity of evidence‑based treatment protocols. These factors combine to produce a wider survival gap for the 15‑19 age group compared with younger children, particularly in low‑ and middle‑income settings.

WHO’s Global Initiative for Childhood Cancer, launched in 2018, released the May report "Measuring Survival, Driving Change" to guide action. The agency has set a target of raising overall childhood cancer survival to at least 60 % by the end of this decade. Achieving this goal will require coordinated investment in infrastructure, training of health‑care workers, and equitable service delivery that reaches underserved regions. The new dataset provides governments and partners with a common methodology to monitor progress, compare performance, and direct funding to the areas where it can most dramatically improve survival outcomes.
