Welcome to Mesothelioma.net - Turning Hope and Faith into Action.

John Chabot, M.D.

Dr. John Chabot is an oncology surgeon and an expert in the surgical treatment of peritoneal mesothelioma. Mesothelioma is already a rare type of cancer, and the peritoneal form is not the most common form. There are few specialists working with patients and researching better ways to treat this rare and deadly type of abdominal cancer. Currently the head of New York Presbyterian Hospital’s Division of Gastrointestinal and Endocrine Surgery, Dr. Chabot also teaches surgery and leads research programs.

Education and Early Career

Dr. Chabot began his college education in engineering, not medicine, earning his undergraduate degree from Tufts University. From there he went to Dartmouth College and earned his medical degree. While working through medical school at Dartmouth, Dr. Chabot also completed a pathology fellowship at the Mary Hitchcock Medical Center.

After completing his medical degree in 1983, Dr. Chabot did his residency and internship at Columbia Presbyterian Medical Center, focusing on transplants. While working on that internship and residency program, he won the Irvington House Institute Fellowship, two surgical research Blakemore prices, and the Upjohn Young Scientist Award.

Career at New York Presbyterian

Dr. Chabot has remained at the same location where he began his residency and internship in 1983. He stayed on at New York Presbyterian Columbia University Medical Center, first as an assistant professor of surgery and as the surgical chief at the Medical Center’s thyroid clinic. Dr. Chabot has described his reasons for staying in one place for so long in his career as being due to the constant innovation encouraged at New York Presbyterian. He has said that the working environment is always stimulating and that he has had the ability to push boundaries and try new treatments and procedures.

His current positions at New York Presbyterian and Columbia include as the vice president of Columbia Doctors, the chief of the Division of Gastrointestinal and Endocrine surgery, and as the Executive Director of the Pancreas Center. He is also the David V. Habif Professor of Surgery for Columbia University College of Physicians and Surgeons. In addition to his leadership roles and acting as an active surgeon, Dr. Chabon has worked in research and has developed a specialization in peritoneal mesothelioma and in pancreatic cancer.

While spending his career at New York Presbyterian, in addition to specializing in peritoneal mesothelioma and pancreatic cancer, Dr. Chabot also developed expertise in several other areas and procedures: thyroid cancer, cancer care, general surgery, pancreatic surgery, liver resection surgery, sarcoma, jaundice, laparoscopic cholecystectomy, and liver cancer.


As a leader in the treatment of a rare cancer like peritoneal mesothelioma, Dr. Chabon has worked hard to engage in both patient care and research to further the knowledge of how to diagnose and manage this disease. His research also extends to pancreatic cancer and other illnesses and surgical treatments. He received government grant to study the latter, acting as the principal investigator for the grant titled, “Pancreatic Supplement for Cancer Center Grant.”

Dr. Chabon has published his research in numerous journals, authoring and co-authoring many papers. Some examples of his research include testing enzyme therapy for pancreatic cancer patients, using CT scans to track the progress of chemotherapy in peritoneal mesothelioma patients, and using a bimodal approach to treat peritoneal mesothelioma with cytoreductive surgery and chemotherapy.

Honors and Awards

Dr. Chabot’s career in treating patients and conducting research into rare diseases like peritoneal mesothelioma has earned him a number of awards, honors, and recognitions. Recently, he was named one of New York Magazine’s Top Doctors. He received the Jerry Gliklich Practitioner of the Year Award from the Society of Practitioners of Columbia University Medical Center, the 2014 Teaching Award in Surgery for Excellence in Teaching and Mentoring from New York Presbyterian’s General Surgery Chief Residents, and the Physician of the Year Award. These are just his most recent awards in addition to many others earned over the years.

There are few surgeons or researchers willing to put time and energy into rare diseases, but the benefits for real people struggling with these diseases are huge. Dr. Chabot has helped so many people struggling with peritoneal mesothelioma simply by specializing in this type of cancer, conducting research, and providing the best possible care along with advanced surgical procedures. As his work and research continue, he will add more knowledge to what we know about the disease and will continue to help patients.
