Disparities in stage at diagnosis of head and neck tumours in Brazil: a comprehensive analysis of hospital-based cancer registries.

ABSTRACT:

Background

The advanced stage of cancer is a determining factor in poor prognosis. Head and neck squamous cell carcinomas (HNSCC) are highly incident in Brazil, but similarly to many Low and Middle-Income Countries, data is limited regarding the proportion of tumours diagnosed at advanced clinical stages and the main factors associated with it. Therefore, this study aimed to identify the factors associated with advanced stage of HNSCC in Brazil.

Methods

Cross-sectional study based on secondary data collected from Hospital-based Cancer Registries (HBCR) between 2000 and 2017. Descriptive data analysis and Poisson regression with robust variance were performed to determine prevalence ratios (PRs).

Findings

Among 145,365 HNSCC cases, 78.2% (90,267/115,371) were diagnosed
