Protein expression correlated with origin of the sample (primary tumor, metastasis or local relapse), using cut-offs previously defined in literature (A) and H-score (B). A. Expression profile of the target proteins in our synovial sarcoma tissue microarray in correlation with origin of sample (primary tumor, metastasis or local relapse), using cut-offs previously defined in literature. Generalized estimating equations were used for statistical analyses. Only statistically significant differences are displayed (p-value < 0.05). B. Expression of proteins of interested assessed using H-score. The mean H-score with range of the proteins of interest is shown in correlation with origin of sample. Linear mixed model was used for the statistical analyses, only statistically significant differences are marked (p-value < 0.05).
