Surgical Treatment of the Five Most Common Types of Cancer in Brazil: 7 Years Analysis Overview

Abstract

Background Surgery is the main treatment for the majority of solid cancers. Studies investigating surgical interventions are a critical asset in improving patient health outcomes. We aim to analyze the temporal and spatial distribution of the surgical treatment of Brazil’s 5 most common types of cancer. Methods The selected cancers were stomach, colorectal and rectosigmoid junction, bronchial and lung, breast, and prostatic. Surgical data were collected from the DATASUS database from 2013 to 2019. Statistical analyses included linear regression tests with a significance level of .05. Results From 2013 to 2019, 19.72% of the diagnoses of all cancers were treated surgically. Only breast cancer didn’t have a significant linear increase in surgeries ( P = .702). Prostatic cancer had the highest annual increase rate and breast the lowest. Analyzing the Brazilian regions, the Southeast had the highest incidence of oncological surgeries, and the Midwest had the lowest. Discussion Brazil’s surgical oncology scenario is progressing positively through the analyzed period. The analysis of the 5 most common types of cancer in Brazil and their progression over the years provides an idea of the cancer surgery capacity in Brazil. There were disparities between the Brazilian regions in all types of cancer. Our study is the first step to better comprehending cancer care in Brazil and the access issues that some areas have. With that, it will be possible to provide better care to cancer patients needing surgical treatment.

Limitations of using the DATASUS database as a primary source of data in surgical research: a scoping review

“…The second domain identified concerns the reliability of data provided by DATASUS (29.78%, n=14). The main aspect highlighted by the authors is dependence of the platform on filling out of forms in the executing hospitals, which generates the possibility of bias in the reporting of information 32 , 33 , 41 , 44 , 45 , 54 , with a probability of including multiple or wrong diagnoses in the database 16 , in addition to the risk of underreporting 31 , 46 . Forms are usually filled by administrative technicians and non-medical professionals, which increases the risk of bias in the information provided 52 .…”

Limitações do uso da base de dados DATASUS como fonte primária de dados em pesquisas em cirurgia: uma revisão de escopo

“…O principal aspecto destacada pelos autores diz respeito à dependência da plataforma do preenchimento de formulários nos hospitais executantes, o que gera a possibilidade de viés no reporte das informações 32,33,41,44,45,54 , com potencial probabilidade de inclusão de diagnósticos múltiplos ou errados nos resultados encontrados na base de dados 16 , além do risco de subnotificação 31,46 12 destaca que a especificação da via de acesso em colecistectomias, por exemplo, é uma informação sujeita a este viés.…”
