Association between socioeconomic status and survival in glioblastoma: An Italian single-centre prospective observational study

Abstract Background To date, no prospective study has been conducted to investigate the role of socioeconomic status (SES) on clinical outcome of glioblastoma (GBM) in Italy, where there is a National Health Service that provides universal coverage regardless of the patient’s economic status. Methods We performed a prospective observational study investigating the association between SES and survival in GBM patients at our institution, a hub centre for brain cancer research and treatment. We included GBM patients who underwent medical treatment or chemo-radiation between April 2017 and December 2017. The SES was measured using the income-brackets, attributed by the Italian Ministry of Finance on the basis of the income of the fiscal family unit, referring to the previous year. Results One hundred and six patients were included in the study. In multivariate analysis, overall survival (OS) correlated significantly with higher-income (HR = 0.623.95% CI 0.467–0.832; p = 0.001) and MGMT methylation status (HR = 0.158.95% CI 0.082–0.304; P  Conclusions SES is an important determinant of prognosis in GBM even in the Italian National Health Service, which provides universal, largely free and relatively comprehensive healthcare. Despite aspirations to achieve equality in healthcare, socioeconomic differences exist and may impact the clinical outcome.
