TP53 and cancer: Kaplan-Meier survival curves (Figure 8) show that patients with higher expression levels of TP53 have significantly worse OS prognoses than those with lower expression levels of TP53 in four cancer types (KIRC, KIRP, OV and UCS), but have better OS prognoses in STAD (log-rank test, unadjusted P-value < 0.05).
