Malcolm V. Brock, M.D., a graduate of the Johns Hopkins University School of Medicine, the Johns Hopkins general surgical residency program and the Johns Hopkins fellowship in cardiothoracic surgery, is a specialist in thoracic oncology, and is a Professor of Surgery and Oncology at the Johns Hopkins University School of Medicine. In additional to clinical thoracic oncology, his clinical interests include surgery for palmar, axillary and pedal hyperhidrosis. 

Board-certified in general and thoracic surgery, Dr. Brock is a surgeon who conducts cancer research at the Johns Hopkins Kimmel Cancer Center, specializing in applying innovative basic science research to patient care. His main research interests are in developing novel molecular biomarkers for solid tumors that can help clinicians diagnose cancer earlier and treat it more effectively. He has studied using DNA-based methods to predict which patients will develop recurrent lung cancer, even after successful surgery, and to predict patients with esophageal cancer who will be sensitive to certain chemotherapy. Dr. Brock has published over 70 original research papers, book chapters and review articles, and has presented often at national and international conferences. He has been the recipient of research funding from the National Institutes of Health (NIH), the Thoracic Surgery Foundation for Research Excellence, the American College of Surgery Oncology Group and the Society of Surgical Oncology.
