title: Endoscopic ultrasonography (EUS) in the staging of malignancy.
abstract: Since first introduced over 20 years ago, endoscopic ultrasonography (EUS) has become established as an important tool in the staging of gastrointestinal malignancies and potentially resectable non-small cell lung cancer. This review describes the current roles of EUS in staging these tumours, highlighting interventional roles, current problem areas and future developments.
