Making the Case for an International Childhood Cancer Data Partnership.

Childhood cancers are a heterogeneous group of rare diseases, accounting for less than 2% of all cancers diagnosed worldwide. Most countries, therefore, do not have enough cases to provide robust information on epidemiology, treatment, and late effects, especially for rarer types of cancer. Thus, only through a concerted effort to share data internationally will we be able to answer research questions that could not otherwise be answered.

Assessment of Barriers and Enablers for Implementing a Population-Based Childhood Cancer Registry in Chennai, India.

Background: Despite most childhood cancer cases being diagnosed in low- and middle-income countries, there is a significant deficit of population-based childhood cancer registries (PBCCRs) in these regions. To address this critical gap, we established India's first dedicated PBCCR in Chennai on October 4, 2022, covering children aged 0-19. This study aims to identify the barriers and enablers to implementing the Chennai PBCCR.

Global patterns of leukemia by subtype, age, and sex in 185 countries in 2022.

In 2022, leukemia ranked as the second most common hematological malignancy after non-Hodgkin lymphoma worldwide. However, updated global estimates of leukemia incidence by subtype are unavailable. We estimated leukemia incidences for different leukemia subtypes by country, world region, and human developmental index using data from the Cancer Incidence in Five Continents databases combined with the GLOBOCAN 2022 estimates of leukemia in 185 countries.

Prevalence of childhood cancer survivors in Europe: a scoping review.

Childhood cancer survivors (CCS) require specialized follow-up throughout their lifespan to prevent or manage late effects of cancer treatment. Knowing the size and structure of the population of CCS is crucial to plan interventions. In this scoping review we reviewed studies that reported prevalence of CCS in Europe.
