NON-HODGKIN LYMPHOMA IN BRAZIL: AN EPIDEMIOLOGICAL OVERVIEW BY SEX AND AGE GROUP (2020–2025)

Abstract

Objective: To analyze the profile of hospital admissions and in-hospital deaths due to lymphoma in Brazil according to sex and age group from 2020 to 2025. Methods: This was an ecological, retrospective, descriptive, and quantitative epidemiological study based on secondary data from the Hospital Information System of the Brazilian Unified Health System (SIH/SUS), available through the Department of Informatics of the Unified Health System (DATASUS). Hospital admissions and in-hospital deaths due to lymphoma in Brazil were assessed according to sex and age group. Data were analyzed using descriptive statistics, including absolute and relative frequencies, as well as the calculation of in-hospital lethality. Results: During the study period, 107,758 hospital admissions and 8,632 in-hospital deaths due to lymphoma were recorded. Males accounted for the highest proportion of both admissions and deaths. Hospitalizations were more frequent among individuals aged 50 to 69 years, whereas deaths predominated among those aged 60 to 79 years. Overall in-hospital lethality was 8.01%, increasing progressively with age and reaching the highest percentage among individuals aged 80 years or older. Conclusion: Lymphoma represented a significant hospital burden in Brazil, particularly among men and older adults, highlighting the need for early diagnosis, specialized access, and individualized care for more vulnerable populations.
