BACKGROUND: A positive oesophageal margin is frequently encountered in total and proximal gastrectomies. It is controversial as to whether a positive oesophageal margin in gastrectomy predisposes to anastomotic dehiscence and loco-regional recurrence. Its independent impact on survival has not been fully addressed. METHODS: A retrospective review of 137 total and proximal gastrectomies for adenocarcinoma was undertaken. Independent prognostic factors were identified in a bivariate and Cox proportional hazards regression model. RESULTS: The prevalence of positive oesophageal margin was 18.2%. A positive oesophageal margin was not associated with increased anastomotic leak (8.0 vs 10.7%; P = 0.51), operative morbidity (32.0 vs 27.7%; P = 0.85) or 30-day mortality (8.0 vs 5.4%; P = 0.48) rates when compared with a negative margin. In addition, it did not predispose to anastomotic (13.0 vs 10.4%; P = 0.47) or regional (22.7 vs 24.5%; P = 0.51) recurrences. In the multivariate analysis the TNM stage and status of the oesophageal margin were the only independent prognostic factors for survival. CONCLUSIONS: A positive oesophageal margin is an independent poor prognostic factor for long-term survival in stomach cancer. All efforts should therefore be made to clear the oesophageal margin in total and proximal gastrectomies.
