CDKN2C and head and neck squamous cell carcinoma: Via univariate Cox regression, CDKN2C expression was related to poor OS in patients with KICH, KIRP (kidney renal papillary cell carcinoma), LGG (brain lower grade glioma), MESO (mesothelioma), and UVM (uveal melanoma) (hazard ratio > 1, p < 0.05) but was associated with favorable OS in patients with CESC, HNSCC, and THYM (Thymoma) (hazard ratio < 1, p < 0.05; Fig. 6A, B).
