The prognosis of intraductal papillary-mucinous neoplasm is superior to that of conventional pancreatic ductal adenocarcinoma. Only a few advanced cases of intraductal papillary-mucinous carcinoma (IPMC) have been reported to date. We herein report the case of a 78-year-old male patient with advanced pancreatobiliary type IPMC with portal vein invasion and liver metastasis. The IPMC invaded the portal vein to form a tumor thrombus and it also metastasized to the liver via the portal vein. After receiving best supportive care, the patient succumbed to the disease following an exacerbation of IPMC 90 days after the initial presentation. On autopsy, a very long tumor thrombus was identified, along with liver metastatic lesions, which had retained the structure of the primary IPMC on histological examination.
导管内乳头状黏液性肿瘤的预后优于传统的胰腺导管腺癌。迄今为止,仅报道了少数导管内乳头状黏液癌(IPMC)晚期病例。我们在此报告一例78岁男性患者,患有伴有门静脉侵犯和肝转移的晚期胰胆管型IPMC。IPMC侵犯门静脉形成肿瘤血栓,并通过门静脉转移至肝脏。在接受最佳支持治疗后,患者在初次就诊90天后因IPMC病情加重而死亡。尸检时,发现了一条很长的肿瘤血栓以及肝脏转移灶,组织学检查显示其保留了原发性IPMC的结构。
