Abstract
Objective: To study the clinicopathologic features, the differential diagnosis and the expression of STAT6 in solitary fibrous tumor (SFT). Methods: Eighty cases of SFT were evaluated. The expression of STAT6, CD34, CD99 and bcl-2 protein was studied in these cases and in other groups of soft tissue tumors by immunohistochemical EnVision method. The results were analyzed and relevant literature were reviewed. Results: The expression rate of STAT6 in SFT was 97.5% (78/80) and that in other soft tissue tumors was 3.3% (3/90). The difference was significant (P<0.05). The expression rates of CD34, CD99 and bcl-2 were 88.8% (71/80), 76.3% (61/80) and 75.0% (60/80) in SFT, respectively, which were significantly different from STAT6 expression rate (P<0.05). Conclusions: The expression of STAT6 in SFT has high sensitivity (97.5%) and specificity (96.7%). The expression of STAT6 in SFT is higher than that of CD34, CD99 and bcl-2. STAT6 may be a useful marker for clinical diagnosis of SFT.
