Kaplan-Meier curves demonstrating the prognostic effects of six immunohistochemistry markers (GATA3, IMP3, HIF-1-α, CK7, CA-IX) on 5 year overall survival (OS) in penile squamous cell carcinoma (pSCC). Note the significant negative impact of GATA3-low status (a), insignificant trends towards worse prognosis in IMP3-high (b), HIF-1-α-low (c), CK7-high (d), and CA-IX-high (e) tumors.
