Showed how radiation, including proton therapy, can be used in liver and pancreatic cancers previously considered unsuitable.

## Summary

Theodore S. Hong is Director of Gastrointestinal Radiation Oncology at Massachusetts General Hospital Cancer Center. He is a radiation oncologist known for showing how radiation, including proton therapy, can be used in liver and pancreatic cancers previously considered unsuitable for it. His selected paper reports a multi-institutional phase 2 study of high-dose hypofractionated proton beam therapy in localised, unresectable hepatocellular carcinoma and intrahepatic cholangiocarcinoma. He leads proton and stereotactic radiotherapy studies in hepatobiliary and pancreatic cancers and neoadjuvant chemoradiation combinations, including losartan-based stromal modulation.
