Role of WNT/β-Catenin Pathway as Potential Prognostic and Predictive Factors in Renal Cell Cancer Patients Treated With Everolimus in the Second and Subsequent Lines

WNT/β-catenin component expression in patients with mRCC had no effect on progression-free survival or overall survival. However, we found that the sE-cadherin level might interact with response to everolimus therapy, although confirmation in future studies is needed.
