摘要: 原发灶不明癌(cancer of unknown primary,CUP)是经组织学证实的转移性恶性肿瘤,其原发肿瘤部位在标准评估和影像学研究的基础上无法识别。通过临床检测、免疫组织化学、基因表达谱、DNA甲基化、下一代测序技术、microRNA检测等方法可对原发灶不明癌进行溯源。随着溯源定位技术的不断发展,更多的方法被开发出用于原发灶不明癌的原发病灶的定位,这些技术将有助于对原发灶不明癌进行评估及诊疗,并改善患者的预后。本文就原发灶不明癌溯源定位方法的研究进展做一综述,以期为临床治疗提供新的方法及理论依据。Abstract: Cancer of unknown primary (CUP) is histologically confirmed, metastatic malignancies with a primary tumor site that is unidentifiable on the basis of standard evaluation and imaging studies. Clinical detection, immunohistochemistry, gene expression profile, DNA methylation, next-generation sequencing, microRNA detection, and other methods were used to trace the origin of CUP. With the continuous development of tracing and localization technologies for CUP origin, more methods for locating the primary foci of CUP have been developed. These techniques will contribute to the clinical evaluation, diagnosis, and treatment of CUP, and improve the prognosis of patients. This article reviewed the research progress of tracing and locating methods of CUP, to provide a new method and theoretical basis for clinical treatment.
