Abstract

Background: Guidelines suggest that surgery for oesophageal and gastric cancer should be conducted in large cancer centres. This national study examined the relationship between hospital volume and outcome in Scotland.

Methods: This was a prospective, population-based study of 3293 consecutive patients with oesophageal or gastric cancer diagnosed between 1997 and 1999. Some 1302 patients underwent surgery and were followed for 5 years after operation.

Results: The 5-year adjusted overall survival rate for the 3293 patients was 18.7 (95 per cent confidence interval (c.i.) 17.2 to 20.2) per cent and that after surgical resection was 39.6 (95 per cent c.i. 36.3 to 43.0) per cent. Death within 1 year after surgical resection was associated with a postoperative complication (odds ratio (OR) 2.5 (95 per cent c.i. 1.6 to 3.8); P < 0.001) or resection margin involvement by tumour (OR 7.2 (95 per cent c.i. 1.1 to 47.5); P = 0.042) after adjustment for age, sex and tumour location. There was no relationship between hospital volume and postoperative morbidity or mortality, nor between survival and volume of patients either for hospital of diagnosis or hospital of surgery.

Conclusion: This population-based study of oesophageal and gastric cancer suggests that the link between hospital volume and long-term survival for patients undergoing surgery requires re-evaluation.
