Overview of lymphoma diagnosis in Brazilian public health system patients: Open data analysis for health care planning

INTRODUCTION: Knowing the information regarding the panorama of lymphoma diagnosis in patients treated in the Brazilian Public Unified Health System from the last 10 years is a challenge for Strategic Health Planning. OBJECTIVE: To characterize the Brazilian population with lymphoma treated in the Brazilian Public Unified Health System between 2008 and 2017 regarding staging, sex, residence site and mortality. MATERIAL AND METHODS: A descriptive, retrospective, and longitudinal trial with secondary data from DataSUS (SIA/SUS and SIM/SUS) obtained from patients with ICD-10 C81−85. RESULTS: There were 70,850 lymphoma cases between 2008 and 2017, of which 55% were male, the median age was 51 years, and 27% had Hodgkin Lymphoma. Most patients (56%) were treated outside the residence city. São Paulo State accounted for 25% of patients. Treatment initiation took more than 60 days in 27% of cases. A total of 45,601 deaths were due to lymphoma (12% Hodgkin Lymphoma and 88% Non-Hodgkin Lymphoma), with a median age 63 years, and were mainly males (55%). Staging data were inadequate in 23% of patients, and analysis was performed only on the valid records. Advanced disease was diagnosed in 58% of patients (60% male; 57% female) and was more common in Non-Hodgkin Lymphoma (62%) versus Hodgkin Lymphoma (49%). DISCUSSION: Late diagnosis interferes with mortality rates. Health promotion and cancer prevention campaigns, especially targeting the male public, and training for early diagnosis and early treatment are needed. CONCLUSION: Effective measures for early diagnosis and treatment are urgently needed for lymphoma control.
