Disease-related survival decreased with increasing TRG in node-negative (N0) patients (P &amp;lt; 0\u00b7001), whereas in node-positive (N+) patients it was poor irrespective of TRG (P = 0\u00b7241). For N0 disease, 3-year survival in patients with MRD (58 (95 per cent confidence interval 26 to 80) per cent) was intermediate between that in patients with no residual cancer (85 (70 to 93) per cent) and non-responders (28 (4 to 59) per cent). Worst prognosis was for N+ disease (21 (9 to 36) per cent).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Node category should be considered when evaluating response to induction therapy in oesophageal or cardia cancer.
