Dr. Calhoun has published over 30 peer-reviewed scientific articles, has been active in national lung cancer clinical trials as well as an invited national and international speaker regarding staging and treatment options for early stage lung cancer. Dr. Calhoun sees an incredible opportunity at St. Elizabeth to turn the often dire diagnosis of lung cancer, with only a third of the patients having curable disease at initial presentation, on its head with the roll out of lung cancer CT screening for at risk patients, earlier detection and more curative therapies offered. Dr. Calhoun comments “It is truly exciting to be involved in the management of lung cancer during this pivotal, paradigm shifting time.” His goal as Medical Director of Thoracic Surgery is to partner in developing a collaborative, multidisciplinary, evidence-based approach to the diagnosis and management of lung nodules and lung cancer at St. Elizabeth. As an exclusively General Thoracic Surgeon (no cardiac), 90% of his operations are minimally invasive. Dr. Calhoun also treats other malignancies and benign pathologies in the chest including esophageal cancer, mediastinal tumors, other lung, pleural space chest wall tumors, pleural space diseases such as empyemas, effusions and pneumothorax as well as hyperhidrosis and thoracic outlet syndrome.
