SPC25 and adrenal cortex carcinoma: Furthermore, in the PFI-related Cox proportional hazards model, SPC25 also showed significant prognostic value in ACC (p < 0.001), KICH (p < 0.001), KIRC (p < 0.001), KIRP (p < 0.001), LIHC (p < 0.001), PRAD (p < 0.001), THCA (p < 0.001), UCEC (p < 0.001), and UVM (p < 0.001) (Fig. 2).
