The outcomes indicated that HMGB1 expression levels were significantly associated with the clinical stage of the following cancer types: Adrenocortical carcinoma (ACC) (p‐value = 0.0239), LIHC (p‐value = 0.0209), SKCM (p‐value = 0.0133) and THCA (p‐value = 0.0348) but not others (Figure S2). Here, HMGB1 is linked to adrenal cortex carcinoma.
