Criação de painel com dados da FOSP: uma abordagem com análise de sobrevivência

Abstract

The Fundação Oncocentro de São Paulo publicly provides several datasets related to cancer; however, these datasets are not presented in an easily interpretable format, requiring preprocessing and organization for better understanding. An elegant and intuitive way to display this information is through interactive panels, or dashboards. This study extracted data from FOSP and integrated them into an interactive dashboard to provide users with a clearer and more dynamic visualization of the information. The dashboard was developed using the Shiny package in the RStudio software. The current version contains 3 main tabs: Dashboard, Análise de Sobrevivência and Sobre. In the Dashboard tab, users can select variables such as escolaridade, idade, sexo, UF de residência, categoria de atendimento, radioterapia, quimioterapia, cirurgia e idade mediana, and the software displays descriptive statistics for the chosen variable. In the Análise de Sobrevivência tab, the survival function is estimated using the Kaplan-Meier method, allowing the selection of International Classification of Diseases (ICD) and filtering by variables such as sexo, idade mediana, categoria de atendimento, radioterapia, quimioterapia e cirurgia. Additionally, Cox and Weibull regression models were implemented to assess the impact of covariates on the risk of death and to understand the behavior of the hazard function over time. The Cox model, of semiparametric nature, allows the study of covariate effects without specifying the baseline hazard function, while the Weibull model, of parametric nature, enables explicit modeling of the risk variation over time. Finally, the Sobre tab provides a brief explanation of the software and details regarding the time period used in the analyses.
