Since CDCP1 is reported to interact with the epidermal growth factor receptor (EGFR)36, whose activity is also associated with Ba/Sq tumors in BCa37, 38, and a cross-talk between these two proteins is already described in other tumor types39–41, further studies investigating the potential CDCP1/EGFR cross-talk are needed. The gene discussed is CDCP1; the disease is neoplasm.
