In addition, high SULF2 expression is significantly (FDR < 0.05) associated with better PFI in LGG (HR = 0.354, p < 0.001) and UCEC (HR = 0.415, p = 0.004) (Supplemental Table S1B) and a favorable prognostic impact of high SULF2 was reported in clear cell renal carcinoma [35] (HR = 0.07, p = 0.015, n = 49) and lung squamous cell carcinoma [37] (HR = 0.11, p = 0.02, n = 51). This evidence concerns the gene SULF2 and squamous cell lung carcinoma.
