Epithelial cell adhesion molecule (EpCAM) is a transmembrane glycoprotein mediating Ca2+-independent homotypic cell-cell adhesion in epithelia.

EpCAM is also involved in cell signaling, migration, proliferation, and differentiation.

Additionally, EpCAM has oncogenic potential via its capacity to upregulate c-myc, e-fabp, and cyclins A & E. It appears to play a role in tumorigenesis and metastasis of carcinomas, so it can also act as a potential prognostic marker and as a potential target for immunotherapeutic strategies.

Since EpCAM is expressed exclusively in epithelia and epithelial-derived neoplasms, EpCAM can be used as diagnostic marker for various cancers.

- prognosis underexpression in RCC

  • A negative EPCAM IHC was found in 1/3 of the patients and was associated with high-grade disease and nodal metastases. (23180689)
  • Kaplan-Meier analyses demonstrated a significant association between positive EPCAM IHC and prolonged overall survival, even in a subset of low risk ccRCC. (23180689)
  • In multivariable analyses, EPCAM represented an independent risk factor of survival throughout all subgroups. (23180689)
  • For localized, low-grade ccRCC, information of EPCAM IHC raised predictive accuracy of a multivariate model by ∼5%, compared to T-stage and grade alone. (23180689)
  • EPCAM is an independent prognostic molecular marker in ccRCC and, especially in localized ccRCC, might be able to provide auxiliary information for a better prognostication. (23180689)
