Together with his colleagues, Dr. Brennan has created the world's largest database of sarcoma patients. This database includes important data on some 8,000 patients treated at Memorial Sloan-Kettering since 1982. Based on this extensive information, they have developed a computer program that is highly effective in predicting patients' chances of surviving soft tissue sarcoma for at least 12 years after their diagnosis. This program, called a nomogram, may help doctors better design treatment to ensure that patients at greatest risk of recurrence can be treated more aggressively, while patients at low risk can avoid unnecessary additional treatment.
Dr. Brennan has lectured throughout the world and authored or co-authored more than 1,000 scientific papers and book chapters, as well as a book on soft tissue sarcoma. He has served as Director of the American Board of Surgery, Chairman of the American College of Surgeons Commission on Cancer, President of the Society of Surgical Oncology, Vice President of the American College of Surgeons, and President of the American Surgical Association, the oldest and most prestigious surgical association in the United States. Dr. Brennan has been awarded Honorary Fellowship in the Royal College of Surgeons in Ireland, the Royal College of Surgeons of Edinburgh and England, the Royal Australasian College of Surgeons, and the Royal College of Physicians and Surgeons of Glasgow and Canada. In 1995, Dr. Brennan was honored with membership in the Institute of Medicine of the National Academy of Sciences, and in 2000 he received the American College of Surgeons' highest award, the Distinguished Service Award.
