About
Dr. Alison L. Halpern is a leading surgical oncologist whose research focuses on the comparative effectiveness of minimally invasive versus open surgical approaches for gastrointestinal cancers, particularly pancreatic and esophageal malignancies. Her landmark 2018 study, cited over 159 times, leveraged the National Cancer Database to compare short-term and oncologic outcomes of minimally invasive pancreaticoduodenectomy (MIPD) versus open pancreaticoduodenectomy (OPD) across low- and high-volume centers, providing critical evidence on the safety and efficacy of these advanced techniques. Dr. Halpern has also made significant contributions to understanding the implications of conversion from minimally invasive to open surgery during esophagectomy, demonstrating that such conversions portend worse short-term outcomes—a finding with direct clinical relevance for patient counseling and operative planning. Her work on national trends in esophagectomy technique use further explores how primary surgeon specialty influences practice patterns. With a growing body of impactful research, Dr. Halpern’s investigations continue to shape surgical decision-making and improve outcomes for patients with complex upper gastrointestinal cancers.
