I have been an attending surgeon at Memorial Sloan Kettering for more than 19 years. I have devoted my career to caring for women with cancerous and noncancerous gynecologic diseases, including cervical cancer, uterine cancer, ovarian cancer, and vulvar cancer. Since 2010, I have served as Deputy Chief of the Gynecology Service, and I have been head of the Ovarian Cancer Surgery Section since 2014.
My mother was an ob-gyn, so I entered my residency thinking I would take over her practice. However, during my first year of training, I was exposed to gynecologic oncology patients and the procedures used to treat their cancers. I saw how quality of care and surgery were so essential to good outcomes for these patients. This inspired me to go into the subspecialty of gynecologic oncology. I wanted to develop an expertise in advanced ovarian cancer surgery because I saw that this was the area where training, skill, dedication, and perseverance made the most difference.
In my clinical practice, I have particular expertise in the use of minimally invasive surgical techniques. Using this advanced technology helps improve outcomes for women with early stage cancers of the ovaries, uterus, and cervix. When appropriate, I offer my patients newer treatment options such as sentinel lymph node biopsy, fertility-preserving surgery, and robotic surgery, as well as panniculectomies (removal of excess fat from the lower abdomen). These techniques improve outcomes, both surgically and cosmetically, and ultimately help improve quality of life for patients.
When women with known or suspected cancers — especially those with advanced ovarian cancer — first come to see me, they are often concerned with removing the cancer as soon as possible. I reassure all my patients that together we will decide on the best treatment plan in the timeliest manner possible. For women who need surgery, we try to schedule their procedure as soon as possible from their initial consultation date, but we also need to take time to make sure the appropriate surgery is done and not rush into a decision. I also remind my patients that we have a team of dedicated surgeons, medical oncologists, radiologists, pathologists, anesthesiologists, and nurses who are all committed to their care. As a result, we have some of the best surgical outcomes for advanced ovarian cancer in the world. Our patients’ quality and quantity of life is our top priority.
Over the past 20 years, I have dedicated much of my research to exploring ways to expand and improve our surgical management of ovarian, fallopian tube, and peritoneal cancer. I have published more than 100 papers on surgery for ovarian cancer and am the principal investigator of many institutional and multi-center trials that are aiming to improve outcomes for women with this disease. In addition, I — along with my colleagues at the University of California, Irvine and UCLA — have recently edited the third edition of the book Ovarian Cancer: Principles and Practice. I have been the lead author of many major ovarian cancer presentations and am passionate about collaborating with my colleagues around the world.
Some of our current clinical investigations at MSK include identifying ways to decrease the need for blood transfusions during surgery, decrease infections, and administer heated chemotherapy directly into the abdomen after the removal of cancerous tumors. I have also worked with international colleagues to establish clinical guidelines for determining appropriate candidates for second and third surgeries in cases of recurrent ovarian cancer. My goal is not only to improve the quality of life and long-term remission for women with difficult cases of very advanced or recurrent disease, but also to offer hope where very little may have existed before.
In addition to my clinical and research activities, I have served on many national and international professional committees, including the American Board of Obstetrics and Gynecology, the Society of Memorial Gynecologic Oncologists, the Metropolitan Gynecologic Cancer Society, and the Gynecologic Cancer Task Force of the American Joint Commission on Cancer. For many years, I have been Director of the Society of Gynecologic Oncology’s annual postgraduate surgical courses aimed at instructing gynecologic oncologists throughout the world on the most up-to-date surgical treatments for women with gynecologic cancers. I am also on the faculty of the European School of Abdomino-Pelvic Surgery in Gynecologic Oncology, based in Italy. Our passionate mission is to improve the care and outcomes of women with gynecologic cancers — not just in our own countries, but everywhere.
Outside of work, my most important role is husband and father of three children. I enjoy playing sports, but over the years have shifted from playing them myself to watching professional sports and being the number-one fan for my son, who plays baseball.
