Two cases of minute carcinoid tumor of the stomach were reported and 167 cases of gastric carcinoid in Japan up to December 1984 were reviewed. In Case 1, two carcinoid tumors of the body were found as sessile polyps of 4.2 and 4.8 mm in diameter, respectively, the latter having been detected two years previously. Case 2 had 60 polypoid lesions on the body and the fundus, ranging from 1.0 to 4.5 mm in diameter. In both cases the tumor invasion was limited to the mucosa and submucosa, although many micronests were found around the polypoid lesions. Among 167 cases of gastric carcinoid in Japan, 12 were 5 mm or less in size and 12 were 6 to 10 mm in size. In the former cases, there was no metastasis while in the latter, metastasis to the lymph nodes was found in 25.0%. We propose that the minute gastric carcinoid should be defined as a tumor not exceeding 5 mm in size with the invasion limited to the mucosa or submucosa. In addition, we emphasized that radical gastrectomy should be performed even for the minute carcinoid tumor because of its multicentricity and invasiveness.
报告了2例胃微小类癌肿瘤，并回顾了截至1984年12月日本的167例胃类癌病例。病例1中，在胃体发现2个类癌肿瘤，分别为直径4.2毫米和4.8毫米的无蒂息肉，后者在两年前已被发现。病例2在胃体和胃底有60个息肉样病变，直径为1.0至4.5毫米。在这两个病例中，肿瘤浸润均局限于黏膜和黏膜下层，尽管在息肉样病变周围发现了许多微小巢状结构。在日本的167例胃类癌病例中，12例肿瘤大小在5毫米或以下，12例在6至10毫米之间。在前一种情况下，没有转移，而在后一种情况下，发现25.0%的病例有淋巴结转移。我们建议将胃微小类癌定义为大小不超过5毫米、浸润局限于黏膜或黏膜下层的肿瘤。此外，我们强调即使是微小类癌肿瘤也应行根治性胃切除术，因为其具有多中心性和浸润性。
