About Me
So compassionate ... I've never met a doctor who cared as much as he did for my father. ~ Patient's Child
A rare combination of gifted scientist and clinician, Gregory Idos, M.D., M.S., earns raves for his bedside manner, while he blazes new research trails.
 
Dr. Idos is a board-certified gastroenterologist and trained cancer geneticist, who specializes in the care of patients with Lynch syndrome, FAP (familial adenomatous polyposis) and other inherited syndromes. The goal of his research is to find new ways to prevent cancer and to improve treatment and care for cancer patients.
 
A UCLA graduate, Dr. Idos has a master’s degree from Keck School of Medicine of USC. He received his medical degree at University of Vermont, continued his residency training at USC and completed his gastroenterology fellowship at Brigham and Women’s Hospital at Harvard. Dr. Idos is an associate professor in Division of Gastroenterology and leads one of the largest multicenter studies examining the benefits and harms of “multiplex” gene panel testing. His research also focuses on the evaluation of novel technologies with the goal of providing new tools for hereditary cancer risk assessment and the development of novel cellular models to elucidate the fundamental mechanisms of microsatellite instability and Lynch syndrome.
 
The recipient of numerous honors and awards, Dr. Idos is part of City of Hope’s growing effort to employ precision medicine to better diagnose, treat, cure and prevent cancer.
Patient ratings
Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy at our comprehensive care and research centers. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
