对17例小胃癌及微小胃癌进行了分析:其临床表现与早期胃癌相似。内镜下为粘膜糜烂、粗糙、小结节、小凹陷、浅溃疡及限局性粘膜不整、破坏或胃小区破坏等形式,肉眼分型中以Ⅱc型居多,Ⅱb型病变的内镜诊断较为困难,误、漏诊率较高,常误诊为慢性炎症。本组中大多数为分化较好的管状腺癌,浸润深度多限于粘膜层内,无淋巴结转移,术后满3年以上者共9例均健在,最长者已达10年。应用流式细胞光度术对3例一点癌进行了DNA含量检测,其DNA含量均异常。
Seventeen cases of small and small gastric cancer were analyzed: their clinical manifestations were similar to those of early gastric cancer. Endoscopic mucosal erosion, rough, small nodules, small depressions, shallow ulcers, and limited local mucosal breakdown, destruction or destruction of the gastric area and other forms, the majority of type IIc in the naked eye classification, endoscopic diagnosis of type IIb lesions is more difficult The rate of misdiagnosis and missed diagnosis is high and often misdiagnosed as chronic inflammation. Most of the patients in this group were well-differentiated tubular adenocarcinomas. The depth of invasion was mostly confined to the mucosal layer. No lymph node metastasis was found. A total of 9 patients who survived for more than 3 years were alive. The longest had reached 10 years. Flow cytometry was used to detect the DNA content in 3 cases of a little cancer, and the DNA content was abnormal.
