核医学分子影像探针应用于神经内分泌肿瘤的研究进展

Application of molecular probes in nuclear imaging of neuroendocrine tumors

神经内分泌肿瘤起源于神经嵴来源的神经内分泌细胞,可分泌多种胺和多肽激素进入全身循环。核医学分子影像探针在神经内分泌肿瘤的早期诊断、临床分期、治疗方案选择、复发和转移病灶的探查中具有重要意义,临床可根据神经内分泌肿瘤细胞增殖及分化程度、细胞表面的分子表达、肿瘤部位选择分子影像探针进行个体化显像。本文就葡萄糖类似物显像剂、生长抑素类似物显像剂、胺前体类显像剂、激素类似物显像剂和酶抑制剂类显像剂等核医学分子影像探针在神经内分泌肿瘤诊断和治疗中的发展及应用进行综述。

Neuroendocrine tumors are a type of heterogeneous tumors originating from neuroendocrine cells derived from the neural crest,which can secrete a variety of amines and peptide hormones.Based on different molecular biomarkers,histologic types and differentiation degrees,individualized nuclear imaging can provide information for the early diagnosis,clinical staging,treatment guidance,and detection of the recurrence and metastasis of neuroendocrine tumor.In this paper,we review the development and application of nuclear medicine molecular imaging probes such as glucose analogs,somatostatin analogues,amine precursors,hormone analogs and enzyme inhibitors in the diagnosis and treatment of neuroendocrine tumors.
