Soft-tissue sarcomas spread predominantly to the lung and it is unclear how often FDG-PET scans will detect metastases not already obvious by chest CT scan or clinical examination.
Adult limb and body wall soft-tissue sarcoma cases were identified retrospectively.
Ewing’s sarcoma, rhabdomyosarcoma, GIST, desmoid tumors, visceral tumors, bone tumors, and retroperitoneal sarcomas were excluded as were patients imaged for followup, response assessment, or recurrence.
All patients had a diagnostic chest CT scan.
109 patients met these criteria, 87% of which had intermediate or high-grade tumors.
The most common pathological diagnoses were leiomyosarcoma (17%), liposarcoma (17%), and undifferentiated or pleomorphic sarcoma (16%).
98% of previously unresected primary tumors were FDG avid.
PET scans were negative for distant disease in 91/109 cases.
The negative predictive value was 89%.
Fourteen PET scans were positive.
Of these, 6 patients were already known to have metastases, 3 were false positives, and 5 represented new findings of metastasis (positive predictive value 79%).
In total, 5 patients were upstaged by FDG-PET (4.5%).
Although PET scans may be of use in specific circumstances, routine use of FDG PET imaging as part of the initial staging of soft-tissue sarcomas was unlikely to alter management in our series.
