总结了着重观察的4例残胃癌和14例残胃再发癌的病理组织学特点:癌变发生在吻合口部者占38.9%;再发癌病例的大体类型、组织学类型、生长方式等两次手术后所见多相同或近似;两组病例的癌旁粘膜除多见萎缩性或萎缩增生性胃炎,中、重度异型增生或肠上皮化生,甚至有的移行到癌之外,可见吻合口附近粘膜呈息肉状增生,粘膜深层腺管囊状扩张或粘膜下异位腺体。文章对残胃癌与再发癌的概念、病因及早期发现进行了初步分析。
The histopathological features of 4 cases of gastric stumps and 14 cases of recurrent stomach cancers focused on the observation were summarized: 38.9% of cases were cancerous at the anastomosis; the general type, histological type, and growth pattern of the recurrent cancer cases The same or similar findings were seen after the second operation; in the two groups of cases, the adjacent mucosa was more common than atrophic or atrophic gastritis, moderately or severely dysplastic or intestinal metaplasia, or even transitional to cancer. The mucous membranes around the mouth showed polypoid hyperplasia, cystic dilatation of the deep mucosa of the mucosa, or submucosal ectopic glands. The article makes a preliminary analysis of the concept, etiology and early detection of gastric stump cancer and recurrent cancer.
