RFC4 and non-small cell lung carcinoma: Additionally, analyses of the online kmplot database (http://kmplot.com/analysis/) consisting of 1432 NSCLC patients and the MSKCC datasets consisting of 177 NSCLC patients showed that high RFC4 levels correlated with shorter overall survival time and progression-free as well as LN metastasis-free survival time (Supplementary Fig. 9c, d), further validating a potentially important role of RFC4 in the prognosis of NSCLC patients.
