title: [Evaluation of DNA content in gastric dysplasia and carcinoma by image cytometry].
abstract: In 30 cases of gastric dysplasia and 10 cases of gastric carcinoma, DNA content was studied by IBAS image analysis system. The mean DNA level increased steadily with the advance of histologic gradation, and the highest DNA content was observed in gastric carcinoma. No case of aneuploidy was found in mild dysplasia. In moderate dysplasia, aneuploid cells were occasionally encountered. Severe dysplasia had a lower percentage (4.48%), and gastric carcinoma was characterized by a high percentage of aneuploid cells (14.54%).
