title: [Hyperplasiogenic polyps and stomach carcinoma risk--experiences following 1074 polypectomies and follow-up studies].
abstract: In 731 hyperplasiogenic polyps which have been removed by endoscopical polypectomy there were ten polyps with an early cancer and eight polyps with severe dysplasias (borderline lesions) as well as one polyp, in which an advanced carcinoma had developed. This is to date the greatest series of hyperplasiogenic polyps with malignant transformation. In addition, in nine patients with hyperplasiogenic polyps carcinomas could be discovered, i.e. a rate for malignancy of 3.8%. It seems that stomachs with multiple polyps are particularly endangered. The recurrence rate on follow-up examinations covering a period of up to eight years was 36.1%.
