TP53 and myxofibrosarcoma: In all histotypes harboring TP53 mutations, DFS was non-significantly shorter in the TP53 mutated compared to TP53 WT STS (Figure S4): median DFS in LMS was 29 versus 67 months (Cox p = 0.33), in UPS 13 versus 49 months (Cox p = 0.16) and myxofibrosarcoma 26 months versus NR (Cox p = 0.37).
