Dr. Dennis Citrin is a board-certified medical oncologist with more than four decades of experience. His current practice is exclusively devoted to patients with all stages of breast cancer. Dr. Citrin works with a team of experts to help patients fight breast cancer at City of Hope Chicago.

Working in the breast clinic, Dr. Citrin provides comprehensive care to those who have breast cancer and other high-risk breast conditions. He talks to patients about treatment options available including surgery, chemotherapy, targeted therapy and radiation. Through open communication and planning, he helps patients at City of Hope develop a comprehensive whole-person approach to cancer treatment.

Dr. Citrin strives to personalize treatment for each of his patients and educate them, so they are a part of the treatment planning and decision-making process. He adds, “I think it’s important develop a relationship with each of my patients so we are all on the same page and we have the patients’ best interests at heart.”

Dr. Citrin earned a Bachelor of Medicine degree (MBCHB), which is equivalent to a medical degree (MD), from the University of Glasgow in Scotland. He then completed a residency in internal medicine at the university. Following his residency, he completed three years of breast cancer research, leading to a PhD. Dr. Citrin was then awarded a Medical Research Council fellowship in cancer medicine, which brought him to the University of Wisconsin-Madison, where he completed a fellowship in human oncology.

Over the next 30 years, Dr. Citrin served on the faculty of several medical schools, including the University of Wisconsin, University of California in San Diego, Albert Einstein College of Medicine in Bronx, New York and Northwestern University Medical School in Chicago.

Rejoining City of Hope in October 2021, Dr. Citrin returns after having a brief break from his original start date in 2004. Previously, he served patients in private practice and as a staff member at Northwestern Memorial Hospital in Chicago. Dr. Citrin is a member of several professional associations, including the American Society of Clinical Oncology, American Association for Cancer Research and the Chicago Medical Society. His research has been presented at numerous national and international conferences and has been published extensively in journals such as Cancer and the Journal of Clinical Oncology.

As an author, Dr. Citrin has written a book, “Knowledge is Power: What Every Woman Should Know About Breast Cancer,” which breaks down the facts about the many types of breast cancer, complemented with real stories from patients who treated under his care at City of Hope in Suburban Chicago. In 2016, Chicago Magazine named him to Chicago’s Top Cancer Doctors list for Medical Oncology.

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.
