Introduction: The aim of this study was to analyze real-life data from a cohort of adult patients receiving atezolizumab in combination with carboplatin and etoposide for first-line treatment of ES-SCLC, in order to assess relative dose intensity (RDI), time-to-treatment discontinuation (TTD), time-to-treatment failure (TTF), progression-free survival (PFS), overall survival (OS) of treatments as well as the correlation between these outcomes.
Methods: An observational retrospective study was conducted. All patients treated with atezolizumab combined with carboplatin and etoposide for first-line treatment of ES-SCLC were included.
