Clinical diagnosis of metastatic cancers of unknown primary site / 国际肿瘤学杂志

ABSTRACT

The management of patients with cancer of unknown primary site (CUP) is a notoriously medical problem. The outcome is bad in most patients. The clinical general characteristics, histopathology, im-aging features and endoscopies can provide some useful information, and the primary site can be detected in part of these patients, but most are not. With the application of molecular biology and positron emission tomography-computed tomography(PET-CT) technology, the detection rate of CUP has increased significantly.
