About Dr. Anusha S Thomas
Dr. Thomas graduated
with honors from Kasturba Medical College, Manipal University, India. She also received the gold medal in Pathology and Internal Medicine during her medical school training. Thereafter, she proceeded to complete Internal Medicine and Gastroenterology at the Houston Methodist Hospital, Houston, TX. Since joining The University of Texas MD Anderson Cancer Center as a clinical faculty in the Department of Gastroenterology, Hepatology and Nutrition, her practice has comprised of caring for patients with complications related to novel immunotherapy for advanced malignancies as well as colon cancer screening and prevention. She is a part of the immunotherapy toxicity working group in the department of Internal Medicine and has contributed to the MD Anderson institutional guideline for the same. She also is fascinated with the role of the human microbiome in gut inflammation. In particular, she is focused on studying and recognizing somatic mutations and consequent clonal expansions in normal colorectal epithelium as influenced by diet and the gut microbiome as some of the earliest events that set nascent cancers along particular trajectories that ultimately will provide for or thwart therapeutic interventions thereby potentially providing game-changing insights into early CRC. She strives to apply MD Anderson's core values of Caring, Integrity and Discovery every day, always placing her patients first so as to provide the best patient care and experience.
