Amongst these five up‐relegated genes, GSTP1 was the only isoform that correlated with both shorter progression‐free (PFS, p = 0.01) and overall survivals (OS, p < 0.0001), using the online public Kaplan–Meier Plotter database (http://kmplot.com/analysis/index.php?p=service&cancer=lung) (Figure 6B,C; Figure S9A,B, Supporting Information). This evidence concerns the gene GSTP1 and cancer.
