Moreover, high expression of NTMT1 was positively correlated with poor DSS and recurrence-free survival (RFS) in HNSCC, ACC, and READ (Figs. 3C and 3D), as well as with poor progression-free interval (PFI) in HNSCC, ACC, and UVM (Fig. 3E). This evidence concerns the gene NTMT1 and head and neck squamous cell carcinoma.
