SMARCB1 expression correlates with patient outcomes and EMT markers in chordomas. (A) Representative immunohistochemical staining of SMARCB1 in typical and chondroid chordomas, showing high and low expression patterns. Scale bars: 50 µm. (B) Kaplan–Meier survival curves stratified by SMARCB1 expression levels. Left: Progression-free survival (PFS). Right: Overall survival (OS). High SMARCB1 expression (red) is associated with significantly better outcomes compared to low SMARCB1 expression (blue). Dotted lines represent 95% confidence intervals. Median PFS: 120 months (high) vs. 52 months (low), P = 0.006. Median OS: 134 months (high) vs. 109 months (low), P = 0.017. n = 23 high expression and 19 low expression samples. (C) Representative immunohistochemical staining of EMT markers (E-cadherin, N-cadherin, cytokeratin, and vimentin) in chordoma samples with high and low SMARCB1 expression. Scale bars: 50 µm.
