title: Current and Future Role of the Gastroenterologist in GI Cancer Management.
abstract: With advances in technology, advances in the understanding of biology of cancer, and the advent of improved and novel therapies, the role of the gastroenterologist has been modified greatly over the past 2 decades, and continues to be shaped by the knowledge, skill, and opportunity to capitalize on the unique position that gastroenterologists hold in the patient care continuum. The gastroenterologist is evolving from a "pure" diagnostician to an endoscopic surgeon, a geneticist, a nutritionist, an immunologist and chemotherapist, and palliative care physician.
