Aims: This study aimed to assess the participants' evaluation of the European School of Oncology–European Society for Medical Oncology virtual masterclasses in clinical oncology (MCOs) organized during the pandemic in 2021. Materials & methods: The participants answered an online evaluation questionnaire at the end of each MCO to evaluate the content and organization of the MCO. Results: The clinical session and case presentation scores ranged between 4.6 and 4.8 over 5. The participants strongly agreed that the MCOs offered updates to improve their knowledge and practice in 68–83% and 52–76%, respectively; 74–90% of the participants considered the quality of the meetings to be excellent. Conclusion: The participants were satisfied with the virtual MCOs during the COVID-19 pandemic. Virtual MCO may be an acceptable alternative educational modality in specific circumstances.
