患者,男,50岁。因“查体发现占位半月”于2017年6月1日入院。

病史资料

现病史:

因“查体发现占位半月”入院。无腹胀、腹痛,无消瘦。外院胃镜显示:慢性萎缩性胃炎;胃角病变性质待定,HP(+)

既往史:高血压病史。

个人史:无特殊

合并用药史:无

检查

查体:生命体征稳定,腹软,无压痛及反跳痛    

实验室检查:无特殊,肿瘤标志物无异常

腹部CT:无异常

胃镜检查:中度慢性萎缩性胃炎,少数腺体肠上皮化生。Hp(+)




治疗方案

诊断性ESD。



ESD术后病理

黏膜呈中度慢性炎,黏膜下见挤压变形的核深染细胞,结合免疫组化,考虑中-低分化腺癌,病变累及基底切缘,未累及四周切缘。

CK(+),Syn(-),CgA(-),CD56(-),Villin部分(+),CDX-2弱  (+),CD3(-),CD20(-),Ki67(+)。



胃腺癌局部切除后:剩余胃组织见部分黏膜缺失,周围有溃疡形成,未见癌残瘤,大弯淋巴结未见转移癌(0/9),小弯侧淋巴结可见转移癌(5/25),手术断端和网膜组织未见癌。

目前诊断

? 胃癌(Bormann I型)T1bN2M0
? 慢性萎缩性胃炎
? 高血压病(3级,极高危)

下一步诊治及随访

? SOX方案化疗,共8周期
? 根除HP
? 随诊

讨论

黏膜下肿瘤样(SMT)胃癌

? 胃癌是上皮组织肿瘤,多起源于黏膜固有层
? SMT样癌临床少见,占手术切除标本的0.2%~0.62%
? 大部分表现为中央凹陷性改变,部分累及固有肌层,大部分为未分化或低分化腺癌

发生机制

? 癌细胞的黏膜下浸润
? 弥漫浸润癌的早期表现

淋巴结转移率 
 
? 有无淋巴结转移是影响早期胃癌预后最重要的独立危险因素
? 低分化EGC淋巴结转移率为12.9%

诊治方案

诊断方法:胃镜、超声内镜、全腹增强CT或MRI、组织病理学

治疗:



EUS在胃癌分期中的应用

● 对于T1b型胃癌,EUS于病理一致率仅为40%
● 凹陷型病变,溃疡性疾病及未分化癌是影响EUS诊断的因素


诊治流程 

胃镜+活检?EUS?ESD?手术

小结

① SMT样癌表现不典型,临床诊断困难;
② 抓住病变的细微改变,多种诊断方法结合;
③ SMT样的诊治,采取最恰当最优化的方案。
