Derycke et al. showed that Nectin 4 is overexpressed in 51.5% of high grade serous ovarian cancer tissues but found no impact on survival in a heterogeneous population comprising different histologies (serous, mucinous, endometrioid, and clear cell), grades, and FIGO-stages in Kaplan-Meier estimates [34]. Here, NECTIN4 is linked to ovarian serous adenocarcinoma.
