Kaplan–Meier analysis of the 66 IMT cases with available outcome data based on extent of resection, age, tumor location, and fusion partners. A, B Patients who underwent subtotal resection (STR) had a significantly shorter PFS and OS compared with patients who underwent gross total resection (GTR; p = 0.0003 and 0.0346, respectively). C, D Patients younger than 14 years old showed a shorter PFS (p = 0.0218) but not OS (p = 6738) compared with patients of or older than 14 years. E, F Patients with infratentorial tumors did not demonstrate a shorter PFS (p = 0.8507) but did show a shorter OS (p = 0.0345) compared with patients with supratentorial tumors. G, H No significant difference in PFS (p = 0.1766) was observed among tumors with different fusion partners; however, patients with EWSR1::ATF1 fused tumors had a shorter OS (p = 0.0247) compared with patients with tumors harboring other fusions
