Eighty-four adenomas (31 mild, 25 moderate, 28 severe atypia), 32 invasive carcinomas and 15 samples of normal mucosa were collected form polypectomy and surgically resected specimens, and their DNA ploidy patterns were examined by microspectrophotometry. The frequency of polyploidy and aneuploidy were 7% and 0% in normal mucosa, 13% and 0% in mild atypia, 20% and 44% in moderate atypia, 32% and 22% in severe atypia and 31% and 53% in invasive carcinomas, respectively. Furthermore, these abnormal ploidy patterns were found frequently in moderate atypia accompanying severe atypia and mild atypia accompanying moderate atypia. These findings suggest that adenomas with moderate atypia might be the early stage of histologically overt cancer. The thin-section method (4 microns or 7 microns) was useful for measuring regional DNA ploidy patterns of colorectal adenoma.
