Advances in gene expression profiling of metastases from unidentified primary tumor / 实用肿瘤学杂志

ABSTRACT

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.
