A multicentre retrospective study of ulcer-carcinoma was carried out in 16 hospitals in China, with the aim of examining the correlation between pre-cancerous lesions and malignant change associated with benign gastric ulcer. Malignant change occurred at 2% over a variable period of 6 months to 15 years. About two-thirds of the ulcer cancers were found to be tubular adenocarcinoma.
