Análise de sobrevida em pacientes com câncer de pulmão tratados no Sistema Único de Saúde (SUS) entre 2002 e 2003

Abstract

The aim of this study was to analyze the survival of patients followed for up to 83 months, as well as analyze survival less than 1 year and up to 5 years in patients older than 18 years undergoing radiotherapy and/or chemotherapy with or without surgery associated, for the treatment of lung cancer in the Unified Health System (SUS) from 01/01/2002 to 12/31/2003. We used a retrospective cohort of patients undergoing cancer treatment, developed by pairing deterministic-probabilistic data between information systems in health: Subsystem Authorization Procedures for High Cost/Complexity (APAC), Outpatient Information System of the Unified Health System (SIA/SUS), Hospital Information System of the Unified Health System (SIH/SUS) and Mortality Information System (SIM). Socio-demographic and clinical characteristics were studied by means of statistical analysis. The results indicate, among other things, that the specific survival for lung cancer less than 1 year was 45% and over 5 years was 16% for patients evaluated in this population. Furthermore, the factors independently associated with specific survival were gender, age, region of birth and residence, staging at diagnosis, occurrence of distant metastases, occurrence of other primary cancer. The findings indicate that in Brazil not only individual factors and clinical, but in context, are associated with survival in lung cancer.
