ABSTRACT
The European School of Oncology (ESO) embarked on an online educational project, starting with live sessions in 2008 (e-ESO). Our scholars and young oncologists identified the need to be offered independent high-level online education with contributions from experts around the world, free of charge and available at any moment. We report on various types of e-sessions, such as grand-rounds, highlights, debates, clinical cases and other sessions. Our audience has grown over the last decade, reaching 11,123 users who have viewed a total of 77,041 sessions since the beginning of 2008. Moreover, our activities on social media platforms have enhanced our visibility, reaching more physicians around the globe. Due to the recent events surrounding the COVID-19 pandemic, online education has proven to be of great value in offering long-distance teaching. We have analyzed the growth of our audience and its attendance over the last 12 years.
