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

John Chabot, M.D.

Dr. John Chabot is an expert in surgical treatment of peritoneal mesothelioma. Because mesothelioma is a rare cancer, and peritoneal mesothelioma is even more rare, there are few specialists treating patients.  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 earned his undergraduate degree in engineering from Tufts University. Although he did not start out with medicine in mind, he earned his medical degree in 1983 from Dartmouth College. While working through medical school at Dartmouth, Dr. Chabot also completed a pathology fellowship at the Mary Hitchcock Medical Center.

Dr. Chabot completed his residency and internship at Columbia Presbyterian Medical Center, where he focused specifically on transplants. During that internship, Dr Chabot won the Irvington House Institute Fellowship, two surgical research Blakemore prizes, and the Upjohn Young Scientist Award.

Career at New York Presbyterian

Dr. Chabot has remained at Columbia University Presbyterian Medical Center, first as an assistant professor of surgery and later as the surgical chief at the Medical Center’s thyroid clinic. Dr. Chabot has stayed at this facility because of the focus and innovation encouraged there. He claims the working environment is stimulating and allows him to treatment push boundaries.

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

During his career at New York Presbyterian, Dr. Chabot has also developed expertise in several other areas. These specialized areas include thyroid cancer, cancer care, general surgery, liver resection surgery, pancreatic surgery, sarcoma, jaundice, laparoscopic cholecystectomy, and liver cancer.


As a treatment leader for rare peritoneal mesothelioma, Dr. Chabon provides patient care while conducting further research on disease diagnosis and management. His research also extends to pancreatic cancer and other illnesses and surgical treatments. He received a government research grant and has served as the principal investigator for the grant titled, “Pancreatic Supplement for Cancer Center Grant.”

Dr. Chabon has published research in numerous medical journals. His research includes testing enzyme therapy for pancreatic cancer patients, treating peritoneal mesothelioma with a combination of cytoreductive surgery and chemotherapy, and using CT scans to track progress of chemotherapy in peritoneal mesothelioma patients.

Honors and Awards

Dr. Chabot has earned a number of awards, honors, and recognitions. Recently, he was named one of New York Magazine’s Top Doctors. He also received the Jerry Gliklich Practitioner of the Year Award from the Society of Practitioners of Columbia University Medical Center and the Physician of the Year Award. These are only Dr. Chabot’s most recent awards and recognitions. He has received many others during his career.

There are few surgeons who invest their time and energy on rare diseases. However, the benefits for real people struggling with these diseases are huge. Dr. Chabot has helped many struggling with peritoneal mesothelioma by specializing in this type of cancer and conducting research. As his work continues, Dr. Chabot will continue to help patients, adding more to what we know about this rare and debilitating disease.
