ZSWIM4 is highly expressed in epithelial ovarian cancer (EOC) and indicates poor prognosis. A IHC staining for ZSWIM4 in EOC tumor tissues and adjacent tissues; representative graphs are presented. B Statistical analysis of ZSWIM4 IHC score in EOC tumor tissues (n = 15) and adjacent tissues (n = 15). C IHC staining of ZSWIM4 in primary tumor tissues from patients with recurrent and non-recurrent EOC; representative graphs are presented. D IHC scores of ZSWIM4 in the recurrent and non-recurrent groups. Re, recurrence. E Statistical analysis of ZSWIM4 protein expression in primary tumor tissues from patients with recurrent (n = 91) and non-recurrent (n = 23) EOC. Re, recurrence. F, G Survival analysis of 114 EOC patients based on ZSWIM4 expression in TMA. Overall survival F. Relapse-free survival G. H Survival analysis of ZSWIM4 expression in OC patients treated with platinum-based drugs using the Kaplan–Meier plotter website
