Research Summary

In 1972, Warshaw founded the world-renowned Massachusetts General Hospital Pancreatic Biology Laboratory, which has contributed significantly to the understanding of the pathogenesis of severe acute pancreatitis and its treatment and to the study of the molecular biology and genetics of pancreatic cancer and other pancreatic tumors.

He has developed new operations for pancreatic diseases, improved the preoperative evaluation of pancreatic cancers with the combined use of CT, laparoscopy and cytology, and is a pioneer in the field of pancreatic cystic tumors.  His group has one of the largest U.S. experiences in management of pancreatic tumors and leads the field in safe outcomes.
