WWTR1 and neoplasm: Using the Kaplan-Meier method and Log-Rank test, it was determined that EHE with worse OS in the following subgroups: tumor size >50mm (Figure 3C), age >50 years old (Figure2-A), multiple organ involvement (Figure 3D), conservative treatment (Figure 3B) and histologic atypia(Figure 2B) (P<0.05).We found that the expression levels of CAMTA1 and TFE3 by IHC (P = 0.152), as well as the presence of the WWTR1-CAMTA1 fusion and TFE3 rearrangement by FISH (P = 0.787), were not statistically correlated with prognosis.
