18F-FDG PET/CT image analysis of clear cell sarcoma of soft tissue / 第二军医大学学报

ABSTRACT

Objective To investigate the 18F-FDG PET/CT features of clear cell sarcoma (CCS) of soft tissue. Methods Ten patients with pathologically confirmed CCS were enrolled in the present study. All patients underwent preoperative 18F-FDG PET/CT scanning, and the image findings and clinical characteristics of the tumors were analyzed. Results The mean maximum standard uptake value (SUVmax) of the primary lesions was 6.52(range, 5-9.6) in the patients. PET/CT revealed lung metastasis in 7 patients, soft tissue metastases in 5, and regional lymph node metastases in 3, with no brain/bone/liver metastases. CT findings showed lung metastases in 6 cases and soft tissue metastasis in one. Conclusion CCS 18F-FDG PET/CT image lacks specificity, but it can better demonstrate the extent and metastases of CCS, helping the accurate, timely, and more targeted therapy.
