Introduction:
CT scan is an important tool in staging of esophageal cancer. Survival can be improved by providing neoadjuvant treatment which depends on stage of esophageal cancer. So it is very important to stage the disease accurately.
Methods:
The objective of this study is to determine diagnostic accuracy of CT scan to stage esophageal cancer. Ct scans of 62 patients included in the study were reviewed by a Consultant radiologist who was blinded to the final stage of tumour. Diagnostic accuracy measured by comparing with histopathological staging.
Results:
Accuracy, sensitivity and specificity of CT for T2 and T3 are 66%, 61%, 68% and 63%, 67%, 56% respectively. Accuracy, sensitivity and specificity of CT for presence of nodal disease are 65%, 59% and 75%.
Conclusions:
Ct scan alone has low diagnostic accuracy for staging Esophageal Cancer.
