Charles S. Cleeland

Charles S. Cleeland, PhD is McCullough Distinguished Professor Emeritus and founding Chair of the Department of Symptom Research at MD Anderson Cancer Center, one of the first departments of its kind anywhere in the world. Dr. Cleeland is the creator of the Brief Pain Inventory (BPI), the most widely used validated tool for assessing cancer pain in clinical practice and research, now translated into more than 50 languages and adopted by regulatory agencies as an accepted patient-reported outcome endpoint for oncology drug approval. His landmark 1994 NEJM study documented the widespread undertreatment of cancer pain across US oncology practices, catalyzing national policy change and updated guidelines from the World Health Organization and ASCO. Dr. Cleeland's research spans pain pharmacology, opioid barriers in minority populations, chemotherapy-induced symptom burden, and neuro-immune mechanisms of cancer-related fatigue, with over 400 peer-reviewed publications and a career h-index reflecting his outsized contribution to oncology symptom science.
