Mortality from soft tissue sarcoma in Rio de Janeiro: epidemiological profile over the last 5 years

Keywords

soft tissue sarcoma - health profile - mortality registries - epidemiology

Introduction: In Brazil, the incidence rate of soft tissue sarcomas (STS) has shown a significant increase, with approximately 3,400 new cases diagnosed annually. This growth can be partially attributed to advancements in diagnostic techniques, which allow for earlier and more accurate detection of these rare neoplasms. Risk factors such as genetic syndromes, immunosuppression, chronic lymphedema, infections, and occupational exposures may also contribute to the rise in diagnosed cases.

Objective: This study aims to analyze the epidemiological profile of soft tissue sarcoma in Rio de Janeiro.

Methods: The DATASUS database was utilized, analyzing records from the Mortality Information System (SIM) based on disease classification according to ICD-10. This study is an observational and detailed investigation of deaths occurring over the last 5 years in the state of Rio de Janeiro. For the analysis, criteria such as marital status, year, race/ethnicity, sex, education level, and age were considered. Additionally, data from the metropolitan region of the state were analyzed. Finally, the records were organized using Excel as a tool for data analysis and investigation.

Results: In the municipality of Rio de Janeiro, 358 deaths from soft tissue sarcoma were recorded, representing 42% of the total cases in the state. The most affected age group was 60 to 69 years, corresponding to 22% of the cases. Among the recorded deaths, 37% were individuals who were married. The predominant education level was 8 to 11 years, accounting for 32% of the deaths. The white population was the most affected, with 61% of the cases, and the incidence was slightly higher among men, who represented 51% of the cases.

Conclusion: The study reveals that the white population and those with lower educational levels are most affected by soft tissue sarcoma. The incidence between sexes did not show significant discrepancies, but there is a direct correlation between increasing age and the number of deaths from sarcoma. Given the rise in mortality, it is essential to better understand the risk factors and analyze incidence trends to improve prevention and treatment strategies, as well as to guide future research in the area.
