胰腺囊性病变有炎性假性囊肿、浆液性囊腺瘤和粘液性囊性肿瘤多种,其中后者又有囊腺瘤和囊腺癌之分.胰腺粘液性囊腺瘤在组织学检查上具有良性肿瘤的特征,但有恶变的潜在倾向,现有的临床和放射学检查不能作出正确的术前诊断,有不少囊性肿瘤曾不恰当地作为假性囊肿处理.经皮穿刺获得的囊液经肿瘤标记物、酶学、粘稠度和细胞学检查有助于区别粘液性和非粘液性囊性肿瘤,但尚无可靠的囊液测定参数可用以区别良恶性粘液性肿瘤,作者试用CA15-3标记物来鉴别这些肿瘤.CA 15-3是—400kD以上的粘蛋白,存在干乳脂肪球膜和包括胰腺癌在内的多种腺癌内.
Pancreatic cystic lesions have a variety of inflammatory pseudocysts, serous cystadenomas and mucinous cystic tumors, of which the latter are divided into cystadenoma and cystadenocarcinoma. Pancreatic mucinous cystadenoma is histologically examined. There are benign tumor features, but there is potential for malignant transformation, the existing clinical and radiological examination can not make the correct preoperative diagnosis, there are many cystic tumors have not properly treated as pseudocysts. Percutaneous puncture obtained The cyst fluid can be used to distinguish between mucinous and non-mucinous cystic tumors by tumor markers, enzymology, viscosity, and cytology, but no reliable cystic fluid measurement parameters can be used to distinguish between benign and malignant mucinous tumors. The authors used CA15-3 markers to identify these tumors. CA 15-3 is a mucin of more than 400 kD. There is a dry milk fat globule membrane and a variety of adenocarcinomas including pancreatic cancer.
