The relative risk of developing cancer after partial gastrectomy for benign ulcer disease, expressed as the standardized incidence ratio, was examined in a population-based cohort comprising 6459 patients operated on between 1950 and 1958. Follow-up to 1983 revealed 1112 patients with cancer versus 1128 expected cases (relative risk 1.0 (95 per cent confidence interval (c.i.) 0.9-1.1)). The overall risk increased over time; it was higher in younger than in older patients but was not related to sex, surgical procedure (Billroth I or II gastrectomy) or diagnosis at operation (duodenal or stomach ulcer). There was an increased risk for lung cancer (relative risk 1.5 (95 per cent c.i. 1.2-1.7)), for oesophageal cancer in patients operated on for stomach ulcer (relative risk 2.2 (95 per cent c.i. 1.0-4.2)) and for cancer of the biliary tract in men (relative risk 1.9 (95 per cent c.i. 1.2-2.9)) and in those operated on for duodenal ulcer (relative risk 1.7 (95 per cent c.i. 1.0-2.8)). The overall risk for genital cancer in women was unchanged but decreased with increasing duration of follow-up and age. Cancers of the nervous system occurred less frequently than expected (relative risk 0.5 (95 per cent c.i. 0.3-0.8)), while the risk for cancer of the buccal cavity, lymphatic and haematopoietic systems, pancreas, breast, prostate, kidney and bladder was unchanged.
