摘要Dear Editor,The global population of individuals aged 65 and older is projected to reach 1.6 billion by 2050[1].Given that urinary tumors,such as bladder cancer(BCa),kidney cancer(KCa),and prostate cancer(PCa),are more common in older adults,the burden on the healthcare system is increasing[2].Recently,Zi et al.[3]conducted a comprehensive assessment of the global burden of 6 urinary diseases from 1990 to 2021,based on the Global Burden of Diseases,Injuries,and Risk Factors Study 2021.This study describes the burden and age-sex distribution of 4 urinary tumors,including BCa,KCa,PCa,and testicular cancer(TCa),and further analyzes cross-country inequalities and projects future incidence rates globally up to 2046 for all these cancers[4,5].Our analyses and visualizations were conducted using the World Health Organization Health Equity Assessment Toolkit and R software(version 4.2.3).
