Internações por Doença de Hodgkin no Brasil: análise epidemiológica e desigualdades regionais e sociodemográficas, 2020–2026

Abstract

Hodgkin disease, also known as Hodgkin lymphoma, is a malignant neoplasm of the lymphatic system characterized by the presence of Reed-Sternberg cells and high curability when diagnosed early (INCA, 2022). Although relatively rare, it has epidemiological relevance due to its predominance among adolescents and young adults and the need for specialized care. In Brazil, the analysis of hospitalizations within the Unified Health System represents an important tool to understand disease burden and inequalities in access to healthcare services (BRASIL, 2026). This study aimed to analyze the epidemiological profile and temporal trends of hospitalizations due to Hodgkin disease in Brazil from 2020 to 2026. This is a retrospective, quantitative, epidemiological study based on secondary data from the Hospital Information System of the Unified Health System (SIH/SUS). Variables analyzed included year of care, sex, age group, race/color, and geographic distribution. During the study period, 34,273 hospitalizations were recorded, with a slight predominance among males (55.5%) and a higher frequency in individuals aged 20–29 years. Mixed-race individuals (parda) accounted for the highest proportion (46.2%), and most hospitalizations occurred in the Southeast region (44.4%). Temporal analysis revealed an increasing trend in hospitalizations, with an initial decline associated with the COVID-19 pandemic followed by recovery.The findings highlight regional and sociodemographic disparities in access to diagnosis and treatment, reinforcing the need to strengthen the oncology care network and implement equity-oriented health strategies.
