01. Doctor Overview

Doctor Overview

Dr. Evan S. Ong currently serves as a surgical oncologist at Swedish Medical Center. Before joining Swedish Medical Center in Seattle, Washington, Dr. Ong was previously an assistant professor of surgery at the University of Arizona Medical Center. While there, Dr. Ong created the Regional and Metastatic Center to address metastasized abdominal cancers. The center largely helped patients with stage 4 disease, approaching their care with a multidisciplinary approach. Speaking of the program, Dr. Ong explained it gave these late-stage patients, who typically had limited treatment options available, more hope for an effective therapy that could provide a longer life expectancy and better quality of life.

Today, Dr. Ong continues to specialize in treating gastrointestinal and abdominal cancers, like peritoneal mesothelioma. One of the most common treatments for abdominal mesothelioma is surgery with hyperthermic intraperitoneal chemotherapy or HIPEC. Dr. Ong is experienced in treating patients with HIPEC, as well as a number of other state-of-the-art treatments like minimally invasive robotic surgery.

Dr. Ong is also an avid cancer researcher. He has authored or co-authored more than 100 medical articles in prestigious, peer-reviewed journals, such as the Journal of Palliative Care, Oncotarget, World Journal of Gastrointestinal Surgery and Technology in Cancer Research & Treatment.
