Image analysis of IHC staining using the percentage positivity score revealed significantly increased IFN-γ and IL-17 expressions in both AOID-associated SS (p < 0.001 and p < 0.001, respectively) and non-AOID-associated SS (p < 0.001 and p < 0.001, respectively) compared to those in the control group (Table 2; Figure 2A). The gene discussed is IL17A; the disease is synovial sarcoma.
