COMMD6 and adrenal cortex carcinoma: High expression of COMMD6 was associated with shorter overall survival (OS) and disease free survival (DFS) in patients with head and neck squamous cell carcinoma (HNSC, P = 0.0084 and HR = 1.7 for OS; P = 0.0056 and HR = 2.0 for DFS), cholangiocarcinoma (CHOL, P = 0.05 and HR = 2.7 for OS; P = 0.029 and HR = 2.8 for DFS) and adrenocortical carcinoma (ACC, P = 0.0077 and HR = 2.9 for OS; P = 0.0053 and HR = 2.6 for DFS) (Fig. S5A–F).
