研究胰腺粘液性囊性肿瘤的组织学类型及其生物学特性。方法:收集我院病理科1966～1997年全部胰腺粘液性囊性肿瘤的临床病理资料,按WHO组织学标准分型,并予随访。结果:295例胰腺上皮性肿瘤中有17例(5.7％)为胰腺粘液性囊性肿瘤;组织学呈良性者9例,交界性和恶性各4例。随访表明,良性者9例、交界性3例及恶性者1例手术后无瘤生存了2～30年;恶性者3例术后2年内死于复发,交界性1例术后10年死于肿瘤恶变、复发。结论:大多数(74.8％)胰腺粘液性囊性肿瘤属手术能治愈的良性肿瘤,WHO组织学分类有助于准确判断患者预后。
To study the histological types and biological characteristics of pancreatic mucinous cystic tumors. METHODS: The clinical pathological data of all pancreatic mucinous cystic neoplasms in our department of pathology from 1966 to 1997 were collected and classified according to WHO histological criteria and followed up. RESULTS: Among 295 cases of pancreatic epithelial tumors, 17 cases (5.7%) were mucinous cystic tumors of the pancreas; 9 were histologically benign, and 4 were borderline and malignant. Follow-up showed that 9 cases of benign, 3 cases of borderline, and 1 case of malignant disease survived for 2 to 30 years after surgery; 3 cases of malignant disease died of recurrence within 2 years after surgery, and 1 case of borderline died 10 years after operation. Malignancy and recurrence of the tumor. Conclusion: Most of the (74.8%) pancreatic mucinous cystic tumors are benign tumors that can be cured by surgery. WHO histological classification can help to accurately determine the prognosis of patients.
