  1. Abbreviations: PoT=proportion of tumour; TNM=tumour, node, metastasis.
  2. Staging data was obtained using TNM, 5th edition (Sobin and Wittekind, 1997, pp 66–69).
  3. Clinicopathological data and its association with the proportion of tumour (PoT) which has been dichotomised into PoT-high (>47% of tumour cells) and PoT-low (⩽47% of tumour cells).
