MKI67 and neoplasm: Number of CD44+ cells higher in early stage EOC and correlated with shorter PFSExpression correlated with high-grade, advanced (III/IV FIGO) EOC in younger (<60) patientsHigher number of CD44+ cells correlated with chemoresistance and shorter DFICD44+ correlated with Ki67 index, p53 positivity and tumor grade in HGSOC, mucinous and endometroid EOC
