Swi/Snf-deficient ECA patients exhibited a worse survival prognosis. Kaplan-Meier analysis and log-rank tests revealed the following: (A) Patients with SwiSnf-deficient ECA had significantly shorter overall survival (OS), patients with ARID1A-deficient, SMARCA2-deficient, and SMARCA4-deficient showed a trend toward shorter OS, the differences were not statistically significant. (B) Patients with Swi/Snf-deficient ECA had shorter disease-free survival (DFS). The stratified analysis further indicated that only patients with SMARCA4-deficient ECA exhibited significantly shorter DFS
