Using the publically available Kaplan-Meir online plotter tool which incorporates gene expression data from 13 ovarian cancer sets including the TCGA dataset , high KRT5 expression was associated with reduced progression-free survival (PFS, HR 1.38; 95% CI 1.16–1.64, P < 0.0001, Figure 3A) and overall survival (OS, HR 1.28 95%; CI 1.05–1.56, P = 0.013, Figure 3B). High KRT6 expression was also associated with reduced PFS (HR 1.26; 95% CI 1.07–1.47, P = 0.005, Figure 3C) but not OS (Figure 3D). No statistical correlation was found between KRT5 or KRT6 expression with patient age at diagnosis, tumor stage, tumor grade, or size of residual tumor after cytoreductive surgery in the TCGA dataset (data not shown).
