The K–M curves showed that patients with HNSCC who had high expression levels of SEC11A, SC5D, CYB5B, HPRT1, and SLC2A3 had lower survival rates, whereas those with HNSCC who had low expression levels of CORO1A and PIK3R3 had lower survival rates (Figures 5A–G). This evidence concerns the gene PIK3R3 and head and neck squamous cell carcinoma.
