Looking forward, given that, in the TCGA database, the linear association between CDC25C mRNA expression levels and the OS of early-stage (stage Ia to IIb) NSCLC patients is significant only among LUAD but not among LUSC patients (data not shown), it is evident that future research will have to separately measure the prognostic yield of CDC25C staining in distinct histological subtypes of NSCLC. Here, CDC25C is linked to non-small cell lung carcinoma.
