原发灶不明转移癌基因表达谱分析技术进展

Abstract

原发灶不明转移癌(CUP)是一类经组织病理学证实为转移性,但经多种临床诊疗手段无法明确原发灶的肿瘤.明确肿瘤原发部位是CUP诊断的第一步,组织病理学、免疫组织化学技术、PET/CT都是临床常用的诊疗手段.基因表达谱分析技术是近年新兴的一种诊断原发灶的方法,具有较高的诊断准确率、敏感性和特异性,有望实现CUP患者的个体化治疗.

Primary lesions unknown metastatic cancer ( CUP) is a class of histopathologically confirmed metastases. However,a variety of clinical diagnosis and treatment can not clear the primary tumor. The identifica-tion of tumor primary site is the first step in the diagnosis of CUP. The histopathology,immunohistochemistry and PET /CT are commonly used clinical diagnosis and treatment. Gene expression profiling technique is a new meth-od for the diagnosis of primary tumor in recent years. It has high diagnostic accuracy,sensitivity and specificity, and is expected to achieve individual treatment of patients with CUP.
