USC patients have limited therapeutic options when the disease becomes resistant to chemotherapy. About 35% of USC overexpress the HER2/neu receptor at 3 + level by IHC and/or are c-erbB2 gene amplified. Trastuzumab emtansine (T-DM1, Kadcyla) is a novel antibody-drug conjugate. T-DM1 may represent a novel treatment modality in USC patients with recurrent, HER2/neu + disease.
