摘要
神经内分泌肿瘤及一些非神经内分泌肿瘤细胞表面均有生长抑素受体高表达。生长抑素类似物如奥曲肽等对生长抑素受体具有亲和力高、作用时间长等特点,并可被放射性核素标记进行肿瘤阳性显像,这对生长抑素受体阳性肿瘤的诊断、分期及预后评价具有较为重要的临床价值,也可作为常规影像学检查的一种有力补充。
Higher expression of somatostatin receptor (SSTR) on the surface of cells of the neuroendocrine tumor and some nonneuroendocrine tumor. Somatostatin analogues, such as octreotide, which holding a long time of action, high affinity with SSTR, and can be labeled by radionuclides and used in SSTR tumor scintigraphy. This is an interesting and important methods for evaluating the diagnosis, stage and prognosis of tumor. So it is a valuable supplemental tool to tumor diagnosis in routine imageological examination.
