Abstract

AIMS:

To assess the strength of agreement between the perceived pre-operative stage of oesophageal tumours as determined by spiral computed tomography (CT) and endoscopic ultrasound (EUS), both alone and in combination, with the histopathological stage.

METHODS:

Sixty patients with oesophageal cancer underwent both pre-operative CT and EUS performed by two consultant radiologists with a special interest in upper gastrointestinal radiology. The strength of the agreement between the radiological stage and the histopathological stage was determined by means of the weighted Kappa statistic (Kw).

RESULTS:

Sensitivity for T and N stages was 58% and 79% for CT, and 72% and 91% for EUS. Specificity for T and N stages was 80% and 84% for CT, and 85% and 68% for EUS. Kw for T and N stages was 0.455 (p=0.0001) and 0.603 (p=0.0001) for CT compared with 0.604 (p=0.0001) and 0.610 (p=0.0001) for EUS. In patients when CT and EUS agreed regarding the T and N stages, the strength of agreement between the radiological and the histopathological stage was greater (Kw T 0.613 (p=0.0001), Kw N 0.781 (p=0.0001)).

CONCLUSION:

CT and EUS are complimentary techniques for the staging of oesophageal tumours, and these results reinforce the importance of specialist radiology in stage directed management.
