OBJECTIVE: In Brazil, it is estimated 6,540 new cases of Endometrial cancer (EC) occur per year. The objective was to analyze the hospitalizations profile and costs of EC in the private health system from 2015 to 2019.

METHODS: The number of EC (ICD-10 54.1) hospitalizations and its associated costs were obtained from the Agência Nacional de Saúde (ANS) database, according to the modalities of health maintenance organization (HMO): self-management (AG), medical cooperative (CM), philanthropy (FT), group medicine (MG) and specialized health insurance (SS). The hospitalization rates (events per 100,000 women) were calculated using the total number of women from ANS. Costs (in Brazilian currency, BRL) were adjusted to 2021 using the official inflation rate (IPCA – IBGE Consumer Price Index). The analysis used descriptive statistics.

RESULTS: There were 3,727 hospitalizations related to EC in the period, with an average of 745 (SD 136) per year. This represented a total cost of 44,523,370.47 BRL and a mean of 10,608,191.00 BRL (SD 1,890,460.00) per year. There was a 67% increase in the hospitalization rate and 60% in the hospitalization costs. The HMO with the highest number of hospitalizations in 2019 was CM (362) and with the highest rate was FT (7.9) followed by AG (4.3). The rank in hospitalization costs in 2019 was: MG (4,319,891.04 BRL), CM (4,000,493.85 BRL), AG (2,026,579.86 BRL), SS (1,443,017.53 BRL) and FT (296,692.31 BRL). FT and CM presented the highest increase in the period for both hospitalization rates (306% and 150%, respectively) and costs (237% and 197%, respectively). SS was the only HMO with a decrease: -31% in the hospitalization rates and -36% in costs.

CONCLUSION: These data suggest that EC imposes an economic burden on the Brazilian private healthcare system, and it has increased over the past 5 years in most HMO modalities.
