Global, regional, and national trends in 34 cancers through a novel burden-quality-of-care framework: a cross-sectional study.
Using Global Burden of Disease data from 1990–2021, this cross-sectional study combines cancer burden and a principal-component-derived quality-of-care index to classify 34 cancers across 204 countries and reports marked socioeconomic, age, and gender disparities, including stagnant quality improvement among adolescents.

Using Global Burden of Disease data from 1990–2021, this cross-sectional study combines cancer burden and a principal-component-derived quality-of-care index to classify 34 cancers across 204 countries and reports marked socioeconomic, age, and gender disparities, including stagnant quality improvement among adolescents.
Research significance
The study provides no evidence for a specific anticancer therapy; it supports the inference that burden–quality stratification could help direct resources, reduce possible overtreatment, and identify underserved populations, but prospective evidence that this framework improves pediatric cancer care or outcomes is required.

BACKGROUND: Current unidimensional cancer evaluation systems limit precise cancer control. This study establishes a novel burden-quality framework that integrates disease burden and quality-of-care index (QCI) to better assess cancer management effectiveness globally. METHODS: The QCI was derived by principal component analysis of six standardized indicators using the Global Burden of Disease data (1990-2021). A four-quadrant framework integrated QCI with disease burden to classify 34 cancers across 204 countries/regions. The sociodemographic index (SDI) and gender disparity ratios (GDR) were used to assess inequalities. RESULTS: Substantial heterogeneity exists in the burden and QCI across 34 cancers. Highly fatal cancers such as TBL cancers (tracheal, bronchus, and lung cancers) and pancreatic cancers are persistently trapped in a "high burden-low quality" dilemma. In contrast, high-burden breast cancer and low-burden thyroid cancer demonstrate superior QCI, though the latter may carry overtreatment risks. Socioeconomic factors have a profound influence on intervention equity, with SDI exhibiting a strong positive correlation with QCI (r = 0.90, P < 0.001) but a significant negative correlation with GDR (r = -0.71, P < 0.001). Notably, the trend of QCI improvement and overall reduction in cancer burden is asynchronous: high-survival cancers and high-SDI regions showed slow QCI gains, middle-SDI regions exhibited substantial increases, while low-SDI areas remained persistently disadvantaged. Demographic disparities further exacerbated these inequities - older populations bore a disproportionate disease burden yet achieved the fastest QCI improvements, whereas adolescent groups maintained high baseline quality but stagnated in progress. Additionally, gender disparities were pervasive, with females receiving better-quality care for most cancers and across most regions. CONCLUSION: This multidimensional burden-quality framework shifts cancer evaluation from singular evaluation to precision intervention. It emphasizes: (1) optimizing resources for high-burden-low-quality cancers, (2) avoiding overtreatment in low-burden cancers, and (3) reducing inequities linked to socioeconomic disparities and vulnerable groups (especially elderly and male patients). This research provides a foundation for precise and equitable global cancer control.
