Staging esophageal adenocarcinoma.
The incidence of esophageal adenocarcinoma has increased dramatically in Western societies over the last 20 years. Most patients present with advanced disease. Stage-dependent treatment protocols require the most complete and accurate staging possible. With all esophageal cancers (ie, adenocarcinomas and squamous carcinomas), it is perhaps most important to identify patients who are unlikely to benefit from aggressive treatment. The performance characteristics and clinical utility of CT scanning, endoscopic ultrasound, FDG-PET, and minimally invasive surgery in staging esophageal cancer are reviewed, including issues relating specifically to staging of adenocarcinomas. These investigations are not mutually exclusive and each has its own strengths and shortcomings. Accurate staging often requires the use of multiple modalities. The optimal staging algorithm for a given practice setting (if it exists) will be determined largely by local variables that include patient population, available technology, and local expertise in applying such technology. A lack of consensus on the effectiveness of therapeutic alternatives (particularly surgical v nonsurgical methods) may also affect the perceived value of the various staging modalities and how they are used.
