UNLABELLED: Synovial sarcoma generally is associated with poor prognosis. With recent advances in molecular biology, it has become apparent not all synovial sarcomas share the same tumor biology. (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) is useful for risk assessment in several types of sarcomas. We therefore assessed the clinical value of (18)F-FDG-PET-derived maximum standard uptake value (SUV(max)) for predicting survival in patients with synovial sarcoma. (18)F-FDG-PET was performed in 44 patients with synovial sarcoma before therapy and resection. SUV(max) was calculated for each tumor and then evaluated for prognostic usefulness along with metastasis at presentation, tumor grade, histopathologic subtype, age, gender, postsurgical margins, anatomic location, and tumor size for overall survival and progression-free survival. SUV(max) ranged from 1.2 to 13.0 (median, 4.35). Pretherapy tumor SUV(max) predicted overall survival and progression-free survival. Patients presenting with a SUV(max) greater than 4.35 had a decreased disease-free survival and were therefore at high risk for having local recurrences and metastatic disease.

LEVEL OF EVIDENCE: Level I, diagnostic study. See the Guidelines for Authors for a complete description of levels of evidence.
