title: Validation of a modified GTNM classification in peri-junctional oesophago-gastric carcinoma and its use as a prognostic indicator.
abstract: OBJECTIVE
  A modified GTNM classification (with additional T and N subdivisions) has been used for many years. The aim of this paper was to validate this classification in a group of patients with oesophago-gastric carcinoma and to see if the more detailed information may be useful.
  
  
  METHODS
  The 3-year survival of 139 consecutive patients who survived resection has been related to the individual values of the modified and international classifications.
  
  
  RESULTS
  A step-wise reduction in the survival was found with increasing values of G, T, N and M. The international T3 value yielded a 17.7% survival rate, when subdivided, rates of 37.5%, 17.3% and 3.2% were found. The international N1 value yielded a rate of 12.9% which subdivided into rates of 25.0%, 18.7% and 7.5%.
  
  
  CONCLUSIONS
  If these results are repeated in a larger and more detailed study, this modified classification may provide added information when discussing prognosis and management.
