Appraisal of compliance with the UICC/AJCC staging system in the staging of gastric cancer. Union Internacional Contra la Cancrum/American Joint Committee on Cancer

Abstract

Background: In the surgical management of gastric carcinoma, regional lymphatic spread is of prognostic importance. The fifth edition of the Union Internacional Contra la Cancrum classification has been shown to be reproducible, practical and of significant prognostic use. The tumour node metastasis (TNM) system requires at least 15 lymph nodes to be acquired and examined for staging to be accurate. This has raised concern over the consistency with which the requisite numbers of nodes would be acquired. This study was performed to assess how consistently surgically managed cases of gastric cancer in the West Midlands fulfilled this requirement to allow accurate staging.

Methods: Data from the West Midlands Cancer Intelligence Unit on all cases of gastric cancer registered from 1998 to 1999 were obtained and the number of lymph nodes documented for each surgically managed case was assessed.

Results: Overall, only 31.0 per cent of surgically resected cases could be assessed accurately according to the TNM system. The proportion staged accurately varied widely across hospitals from 10.9 to 76.0 per cent.

Conclusion: These results reflect the need for improved N staging across the region to aid the appropriate multimodal treatment of patients.
