Long-Term Partial Remission with Capecitabine/Trastuzumab in a Patient with Metastatic Breast Cancer Following Progression on Trastuzumab Alone

摘要

Even after tumor progression, trastuzumab seems to retain its antitumor activity which is potentiated by the combination with a chemotherapeutic agent.
