Clinical stage T1–T2N0M0 oesophageal cancer: accuracy of clinical staging and predictive factors for lymph node metastasis†

Abstract

Clinical staging using both EUS and PET demonstrated high accuracy for predicting cT1N0M0 oesophageal cancer pathological staging, but was inadequate for predicting staging for cT2N0M0 cancer. Clinical factors such as SUVmax and tumour differentiation could help select patients with cT1-T2N0M0 tumours that might be upstaged because of unexpected LN metastases.
