Improved assessment of supraclavicular and abdominal metastases in oesophageal and gastro-oesophageal junction carcinoma with the combination of ultrasound and computed tomography.

The purpose of the study was to evaluate ultrasound and computed tomography in the assessment of distant metastases, supraclavicular and abdominal, in 113 patients with carcinoma of the oesophagus and gastrooesophageal junction. Ultrasound and computed tomographic findings were compared with the cytological data in 29 patients and with the surgical data in 84 patients. In assessing distant metastases, ultrasound and computed tomography had a sensitivity of 61% and 70%, and a specificity of 93% and 85%, respectively (p = 1.0). When ultrasound and computed tomography were combined the sensitivity increased to 83% and the specificity decreased to 81%. There was no significant difference in the assessment of supraclavicular metastases (p = 0.8), coeliac metastases (p = 1.0) or liver and other non-lymphatic abdominal metastases (p = 1.0) on ultrasound or computed tomography. The results show that both ultrasound and computed tomography should be used for assessment of distant metastases and abnormalities confirmed by image-guided biopsy.
