The management of patients of CUP remains a clinical challenge. The purpose of this study was to evaluate the clinical applications of integrated 18F-fluorodeoxyglucose positron emission tomography/computed tomography （FDG PET/CT） information in patients with CUP, including detecting the occult primary tumor and effecting on disease therapy.展开更多
