Trends in malignant neoplasm of bone and articular cartilage related mortality among older adults in United States (1999-2020).

Introduction: Malignant neoplasms of bone and articular cartilage, although rare, are associated with substantial morbidity and mortality, posing a serious health burden. Understanding the trends in mortality related to these cancers is crucial for developing targeted interventions and improving patient outcomes. This study aims to analyze long-term mortality trends, identify demographic and geographic disparities, and uncover potential factors driving changes in mortality rates. Methods: This retrospective study analyzed mortality rates among individuals aged 65 and older from 1999 to 2020 using CDC WONDER death certificate data, abstracting demographics, geographic factors, and urban/rural status. Results: From 1999 to 2020, 18,205 adults aged 65 and older died from malignant neoplasms of bone and cartilage. The age-adjusted mortality rate (AAMR) started at 20 per 100,000 in 1999 and steadily declined until 2012 (APC: -1.12). However, from 2012 onwards, there was a notable reversal, with the AAMR rising sharply to 23.8 by 2020 (APC: 4.73). Men had higher mortality rates than women, with NH Black individuals showing the highest rates among races. Southern states and nonmetropolitan areas had elevated AAMRs, suggesting targeted interventions for better outcomes and lower death rates. Conclusion: The findings highlight significant inequities, with Southern states and nonmetropolitan areas showing elevated age-adjusted mortality rates (AAMRs). These geographic disparities underscore the urgent need for targeted public health interventions in these regions to improve cancer outcomes and reduce mortality. Addressing these gaps is essential for achieving more equitable health outcomes, particularly in high-risk populations.
