Get to Know Dr. John Cho
Dr. John Cho is a radiation oncologist playing a key role in pioneering efforts to improve treatment of pleural mesothelioma through groundbreaking clinical trials.
Cho is the principal investigator in the latest trial with the acronym SMARTEST, which is Surgery for Mesothelioma After Radiation Therapy using Exquisite Systemic Therapy.
The trial involves variations from earlier studies called SMART and SMARTER, hoping to find the best combination treatment to help patients extend their survival significantly.
Cho works closely with thoracic surgeon Dr. Marc de Perrot, another specialist in pleural mesothelioma. His research interests also include stereotactic body radiation therapy and intensity modulated radiotherapy.
Princess Margaret Cancer Centre in Toronto, Canada, was one of the first to study targeted radiation prior to major surgery, recognizing the way it could reduce or slow any tumor recurrence.
“This is the latest, greatest version,” Cho said. “We’re taking the next step.”
In a cohort of 19 patients, Cho’s earlier trial produced a median survival of 5.5 years, the first time a multimodality study exceeded the five-year mark for mesothelioma.
