EXPERTISE

 


RESEARCH INTERESTS

As a radiation oncologists, Dr. Ch’ang is interested in clinical radiation as well as modern radiation biology of hepatobilliary and gastrointestinal malignancies. Her laboratory work is majoring in the contribution of bone marrow stem cells in intestinal repair after radiation. Similar studies are developed for studying bone marrow stem cells with tumor microenvironment after radiation. She is also interested in investigating combination effect of molecular targeting agents and radiation. Besides animal studies, she designed clinical studies for hepatocellular carcinoma patients undergoing local radiation. The blood perfusion within tumor was measured by dynamic contrast enhanced magnetic resonance imaging before, during and after radiation treatment course. A series of clinical trials for pancreatic cancer patients were also initiated by Dr. Ch’ang in collaboration with Professor Li-Tzong Chen.
