Ghassan Abou-Alfa, MD
Memorial Sloan-Kettering Cancer Center

Ghassan Abou-Alfa joined Memorial Sloan-Kettering Cancer Center in 2001. He earned his medical degree from the American University in Beirut. In 1992, he joined the Yale School of Medicine for postdoctoral training. He received his MBA degree from Columbia University in 2016. Ghassan specializes in treating patients with gastrointestinal malignancies. His work focuses on investigating novel targeted therapies in clinical studies, and advocates for greater awareness of the disease's global impact. Ghassan is honored to chair the National Cancer Institute Hepatobiliary Task Force, and the AIDS Malignancy Consortium (AMC) Non-AIDS Defining Malignancies (NADC) Liver/GI Task Force. He also co-chairs the hepatobiliary cancers subgroup of the Alliance cooperative group.

Ghassan work focuses on hepatocellular carcinoma (HCC) which affects a diverse population from many cultures and economic backgrounds: truly a global disease. Ghassan continues his work to help advance the field. His research focuses on incorporating small biological molecules into standard cancer therapies. In recent years, he led the initial international effort that helped evaluate sorafenib in HCC. He later and in a trial led by the multi-cooperative groups, they investigated combining sorafenib with doxorubicin, an effort that is supported by the National Cancer Institute. Ghassan continues to lead several international efforts and is involved in conducting clinical trials with colleagues around the world. An effort that helps better understand the challenges of managing a disease with varying risk factors, in different regions of the world.

Ghassan has taken on an advocacy role as research funding has lagged despite the worldwide impact of this disease. He co-authored with hepatobiliary surgeon the chairman of surgery at U. Penn Ronald DeMatteo 100 Questions and Answers About Liver Cancer book, now in its third edition. He also co-authored with his wife Eileen O�Reilly, also a medical oncologist at Memorial Sloan Kettering Cancer Center, a similar book on bile ducts cancers now in its second edition.

Part of the global effort, Ghassan helped chair multiple training course for oncologists globally, and helped sustain monthly videolinked educational conferences with different regions of the world, for almost a decade now.
