A specialist in lung as well as head and neck cancer, Dr Seiwert looks for new ways to combine traditional treatments, such as chemotherapy and radiotherapy, with the latest targeted agents in order to improve treatment results and decrease side effects. In the laboratory, he studies targeted therapies that disrupt specific pathways vital to cancer growth and metastasis. He studies which novel drugs appear most promising, which individual tumors are more likely to respond to these treatments, and how to successfully combine therapies. Dr Seiwert uses this preclinical knowledge to develop new treatments for use in clinical trials, and to ultimately improve patient care.
