Long-term remission of excessive liver metastases in a breast cancer patient with chronic alcohol abuse using a monotherapy with trastuzumab.

We report on the successful treatment of a 43-year-old breast cancer patient with excessive liver metastases and chronic alcohol abuse. After first occurrence of hepatic metastases, systemic and interventional therapies were performed, and resulted in short-term partial remission. Finally, an excessive progression of the hepatic metastases was diagnosed. A systemic therapy with weekly trastuzumab (Herceptin) infusions was induced and a complete remission was achieved that is ongoing now for over 45 months.
