摘要
目的：探讨18F-氟代脱氧葡萄糖（2-deoxy-2-[F-18]fluoro-D-gluocose，FDG）PET/CT用于寻找转移性肿瘤的原发灶的作用。方法：对54例病理细胞学诊断为转移性肿瘤的患者进行了18F-FDG PET/CT显像，以寻找其原发灶。结果：41例患者（41/54，75.9%）PET/CT检出原发灶。13例（13/54，24.1%）PET/CT未发现原发灶。35例患者（35/54，64.8%）PET/CT发现其他影像学手段未发现的新病灶。结论：PET/CT在寻找转移性肿瘤的原发灶有较大的临床价值。
Abstract
Objective: To evaluate the role of whole body PET/CT scan with (18)F-fluorodeoxyglucose(FDG) in the detection of the primary tumor in patients with metastatic cancer from unknown primary origin. Methods: Fifty-four consecutive patients, with biopsy proven tumor metastases from unknown primary site, underwent a whole-body FDG-PET/CT study. Results: The primary tumor site was correctly identified by FDG-PET/CT in 41 patients(41/54, 75.9%). In 13 patients(13/54, 24.1%), the primary tumor site was not localized. However, in 35 cases(35/54, 64.8%) of them, FDG-PET/CT scan identified further unexpected metastases, modifying the stage of disease. Conclusion: Our data strongly support that the whole body FDG-PET/CT is a useful tool in the evaluation of patients with cancer with unknown primary site and PET/CT is able to find more metastatic lesions.
