概要:
Macroscopic differential diagnosis of colorectal cancers was discussessed based on the results of the histological and macroscopic observation of 1842 advanced cancers, early cancers and adenomas. Among the neoplastic lesions in colon and r ectum in our series, 95.3% of those measured more than 30mm in the largest diameter were advanced cancers, and none was advanced those less than 10mm. Lesions between 10mm to 30mm, about a half of the polypoid lesions more than 25mm was advanced cancers, and 96.5% of the lesions in size more than 15mm was advanced if central depression be present. An certain numbers of early cancers were well discriminated from adenomas by the statistical analysis based on the relationship between size and macroscopic configuration of the lesions; that flat and sessile lesion more than 10mm and, subpedunculated and pedunculated lesions more than 15mm were suspectable of being early cancers. Among them flat and peduculated lesion have high possibility of mucosal cancer and, sessile and subpedunculated, of submucosal cancer. Submucosal cancers were also well detectable to recognize their specific surface apappearance and the amount of their invasion was also able to estimate to notice the evertion of non-neoplastic mucosa surrounding the lesions. 続きを見る
