In this issue of Gastrointestinal Endoscopy Clinics of North America, guest editors Drs. Kenneth J. Chang and Jason B. Samarasena bring their considerable expertise to the topic of The Endoscopic Oncologist. The practice of gastrointestinal endoscopy intersects with oncology in many ways, much of it involving pre-cancerous conditions. But the endoscopist's role in diagnosing, staging, and treating cancer patients is expanding. This issue is devoted to the current and future role of the endoscopic oncologist, with topics such as endoscopic diagnosis of luminal gastrointestinal cancer and extra-luminal cancer; endoscopic resection for early cancer; and more.
