He is a practicing oncologist who is actively involved in the surgical and chemotherapy management of women with ovarian, endometrial and lower genital tract cancers. This includes minimally invasive laparoscopic surgical approaches. He also has developed a research program that focuses on the molecular-genetic alterations involved in malignant transformation of the ovarian and endometrial epithelium. He has published over 300 peer-reviewed papers in these areas. The objectives of his research include 1) identification of ovarian cancer susceptibility polymorphisms through a population-based case-control molecular epidemiologic study, and 2) use of genomic approaches to elucidate the molecular heterogenetity of ovarian cancer. Thirty fellows and residents have worked in his lab, several of whom are now funded investigators. His research efforts have been recognized nationally and he has received awards for best oral presentation at the annual meetings of both the Society of Gynecologic Oncology and the International Gynecologic Cancer Society. He has served as editor of several books in the field including Principles and Practice of Gynecologic Oncology. Dr. Berchuck also has a major commitment to national activities, and was President of the Society of Gynecologic Oncology in 2008. He served as chair of the scientific advisory committee of the Ovarian Cancer Research Fund (http://www.ocrf.org) in New York City. Finally, he is also head of the steering committee of the international Ovarian Cancer Association Consortium (OCAC), a group of 50 case-control studies that are working together to identify ovarian cancer susceptibility polymorphisms.
