As displayed in Table S4, all the subgroup analysis conducted according to chemotherapy regimen (combination or doxorubicin alone) and setting (advanced or neoadjuvant), showed a non-significant increased response in TP53-mutated sarcomas, except for doxorubicin alone in the neoadjuvant setting (n = 4; ORR = 0 in both groups). The gene discussed is TP53; the disease is sarcoma.
