Overall and recurrence-free survival times of patients categorized by (A and B) subcellular localization of HDAC6, (C and D) level of HDAC6 expression, and (E and F) positive and negative PD-L1 staining. Follow up data is missing for some patients who dropped out from follow up and therefore the number of patients in the survival analysis is lower than that of total patients. PD-L1, programmed death-ligand 1; HDAC, histone deacetylase.
