ESO is proposing a comprehensive course for oncology trainees in Europe intended to bridge the gap in education between courses for students and ESO’s well-known Masterclasses. The course aims to provide orientation to the guiding principles of multidisciplinary oncological management and life as a modern oncologist. Although some of the principles underlying oncology practice are similar to those in other branches of medicine, sub-specialisation has reduced the exposure of medical students and junior residents to oncological concepts and practice. New oncology trainees face a number of specific challenges. These include navigation of an extensive curriculum with no clear starting point, a rapidly evolving clinical landscape, and increasing clinical demands. During training, residents must also strategically plan their careers, manage any academic focus, and maintain a healthy work-life balance. The course is divided into 2 parts: Part 1: participants will be asked to view pre-recorded lectures which were recorded during the 1st edition of the course in Ljubljana, Slovenia in 2022 and will be made available on the e-Eso website. Part 2: in-person event.
