Intramucosal carcinomas of the large intestine, polypectomized from 1988 to 1992 were investigated. Out of 111 lesions of intramucosal carcinoma, 106 cases (95.5%) co-existed with adenoma. The incidence of co-existence with adenoma was 0%, 14.4%, 31.5%, 26.1%, 18.9% and 9.0% in the lesions within 4mm, 5-9mm, 10-14mm, 15-19mm, 20-29mm, and over 30mm in diameter, respectively. The incidence of gross findings in the co-existed cases of cancer and adenoma was 0.9%, 15.1%, 32.1%, and 51.9% for IIa, Is, Isp, and Ip types, respectively. Histological incidence of co-existed adenomas was 63.2%, 31.1% and 5.7% for tubular, tubulovillous and villous types. Occupation rate of cancer tissue was within half in the majority of co-existed lesions.
对1988年至1992年间切除的大肠黏膜内癌进行了调查。在111例黏膜内癌病变中，106例（95.5%）同时存在腺瘤。直径在4mm以内、5-9mm、10-14mm、15-19mm、20-29mm和超过30mm的病变中，腺瘤并存的发生率分别为0%、14.4%、31.5%、26.1%、18.9%和9.0%。癌与腺瘤并存病例的大体表现发生率，IIa型、Is型、Isp型和Ip型分别为0.9%、15.1%、32.1%和51.9%。并存腺瘤的组织学发生率，管状、管状绒毛状和绒毛状类型分别为63.2%、31.1%和5.7%。在大多数并存病变中，癌组织的占有率在一半以内。
