To determine the survival effect of S100A family members (eg S100A2, S100A4, S100A6, S100A10, S100A11, S100A13, S100A14 and S100A16) in PC patients, we examined the correlation between mRNA expression and OS or RFS on log‐rank test using KM plotter database. This evidence concerns the gene S100A11 and pachyonychia congenita.
