Yi-Jen Chen, MD, PhD

Department of Radiation Oncology, City of Hope National Medical Center, City of Hope, Duarte, CA, USA

Dr. Chen received his medical doctorate from National Yang-Ming University in Taipei, Taiwan. He earned his Ph.D. from Tokyo Medical & Dental University in Tokyo, Japan. After establishing a career as a GI surgical oncologist in Taiwan, he then furthered his oncologic training in radiation oncology at University of California, Irvine. Dr. Chen became board certified and was recruited to City of Hope Medical Center in 2002 to provide patient care and conduct clinical research. He has strived and specialized in the fields of radiotherapy for gastrointestinal and gynecologic malignancies.

As a physician, Dr. Chen strongly believes “treat others like treating your own”, a motto that has been passed down from his physician father, who is a gastroenterologist. As a scientist, “developing more effective cancer treatment”, has been his lifetime mission. In 2012, Dr. Chen was named as “Educator of the Year” by the Association of Residents in Radiation Oncology for his excellence in teaching and enthusiastic support of residency training. Dr. Chen was honored as “Top Doctor” in the field of Radiation Oncology by the Pasadena Magazine in 2009, 2011, 2012 and 2013.

The major goal of Dr. Chen’s research is to apply novel radiation modality for patients with gastrointestinal and gynecologic malignancies. He has authored or co-authored more than 50 publications in peer-reviewed journals. For years, he has focused in the application of new intensity modulated radiation therapy (IMRT) technology for patients with esophageal, gastric, pancreatic, anal, endometrial, and cervical cancers. One of his publications on the impact of the number of resected and involved lymph nodes on esophageal cancer confirmed the correlation between increasing number of positive lymph nodes and poorer survival for patients with esophageal cancer, which has led to the revision of current AJCC staging for esophageal cancer based on the number of regional lymph nodes containing metastasis.

Currently, Dr. Chen serves as a clinical professor within the Department of Radiation Oncology at the City of Hope Medical Center and he is a member of the National Comprehensive Cancer Network Colon/Rectal/Anal Cancer Guideline Panel, which develops national guidelines for the treatment of related GI cancers.
