Introduction: The association between socioeconomic status and cancer prognosis has been demonstrated in several countries. Despite the existence of indirect evidence of this phenomenon in Brazil, few studies in this regard are available.
Objectives: The objective of the present study is to analyse socioeconomic related survival gaps for patients diagnosed with breast, cervical, lung, prostate, and colorectal cancer in the cities of Aracaju (SE) and Curitiba (PR).
Objective: To study the impact of socio-economic status and ethno-racial strata on excess mortality hazard and net survival of women with breast cancer in two Brazilian state capitals.
Method: We conducted a survival analysis with individual data from population-based cancer registries including women with breast cancer diagnosed between 1996 and 2012 in Aracaju and Curitiba. The main outcomes were the excess mortality hazard (EMH) and net survival.
Objective: To analyze the time trend and the factors regarding the diagnosis of late-stage breast cancer in Brazil from 2000 to 2012.
Methods: We conducted a retrospective cohort study using data from hospital-based cancer registries. Joinpoint regression was used to analyze the time trends of stage at diagnosis.
Background: Despite depression being one of the most prevalent mental disorders in the world, access to treatment is still insufficient, especially in low- and middle-income countries. The aim of this study is to investigate differences in access to treatment for depression according to socio-demographic characteristics, geographical area and multi-morbidity in a nationally representative sample of individuals with depression.
Methods: This study analyses data from the National Health Survey (Pesquisa Nacional de Saúde - PNS), a Brazilian household-based nationwide survey, which comprises 60,202 adults (aged 18 years or older).
