Pancreatic carcinoid tumours are extremely infrequent. Usually, the biological behaviour is indolent and diagnosis is late and often casual. We present the case of a patient initially diagnosed as having liver metastasis of unknown origin. PET identified a primary pancreatic site and the initial histologic diagnosis was adenocarcinoma. Following an uncertain response to chemo- and radio-therapy the repeat histologic assessment indicated a carcinoid tumour of the pancreas. After complete surgical resection and liver transplantation, patient remains free of disease.
The co-existence of several diseases with similar morpho-structural features makes diagnosis complicated. PET is of uncertain use in the evaluation of carcinoid tumours, and is considered inferior to 111Indium-octreotide scan. The only curative treatment is surgical resection, with liver transplantation as a valid option in the treatment of these tumours.
胰腺类癌肿瘤极为罕见。通常,其生物学行为惰性,诊断较晚且往往偶然。我们报告一例最初被诊断为不明来源肝转移的患者。正电子发射断层扫描(PET)确定了胰腺原发部位,最初的组织学诊断为腺癌。在对化疗和放疗反应不确定后,再次组织学评估显示为胰腺类癌肿瘤。经过完整的手术切除和肝移植后,患者无疾病复发。
多种具有相似形态结构特征的疾病共存使诊断变得复杂。PET在类癌肿瘤评估中的作用尚不确定,且被认为不如铟-111奥曲肽扫描。唯一的治愈性治疗是手术切除,肝移植是治疗这些肿瘤的有效选择。
