## TL;DR

Severance Hospital houses Yonsei Cancer Center and Korea's first heavy-ion (carbon) therapy centre (2023).

## Summary

Severance Hospital, part of Yonsei University in Seoul, houses the Yonsei Cancer Center and opened Korea's first heavy-ion carbon therapy centre in 2023; it ranks twenty-second in the Newsweek/Statista oncology list. It matters for its carbon-ion programme, for lung and gastric cancer trials, and for leadership in robotic and minimally invasive surgery, with Byoung Chul Cho, Hye Ryun Kim, Sun Young Rha, Joohyuk Sohn and Sang Joon Shin among its clinicians. OnCo links it to the MARIPOSA paper on amivantamab plus lazertinib in EGFR-mutated lung cancer and to the Korean Cancer Study Group. Whether carbon ions deliver benefits that justify the cost over protons and photons is still being worked out. Its carbon-ion and robotic surgery programmes are the reasons to read on.
