TP53 and neoplasm: High-p73/high-p53 tumours were likely to be serous tumours (p = 0.011), whereas low-p73/low-p53 staining was more likely in low-grade tumours (p = 0.046) with no residual tumours after surgery (p = 0.005) (Supplementary Table S6), showing better PFS (p = 0.006) (Figure 1D) but not OS (p = 0.332) (Supplementary Figure S2A).
