From October 1987 to March 1991, 21 (8%) superficial early cancers were found among 256 early colorectal cancers (Dukes A and B1). Superficial early cancers were defined as early cancers less than 3 mm in height. These tumors were found scattered throughout the large intestine and were often observed as reddish spots, which were easily overlooked without careful observation. Histologically, 19 (90%) of them were well-differentiated adenocarcinomas, and five (24%) of them reached the submucosal layer. Eighteen (86%) of them were not associated with adenoma.
1987年10月至1991年3月期间,在256例早期结直肠癌(Dukes A和B1期)中发现了21例(8%)浅表早期癌。浅表早期癌定义为高度小于3mm的早期癌。这些肿瘤散在于整个大肠,常表现为红色斑点,若不仔细观察很容易被忽视。组织学上,其中19例(90%)为高分化腺癌,5例(24%)侵犯至黏膜下层。其中18例(86%)与腺瘤无关。
