[Five Cases of Pseudocirrhosis during Eribulin Treatment for Breast Cancer].

Pseudocirrhosis, which is radiologically and clinically similar to liver cirrhosis, may develop following chemotherapy for breast cancer with liver metastasis. There are few reports of eribulin treatment. We report 5 patients with metastatic or recurrent breast cancer who developed pseudocirrhosis during eribulin treatment. All patients had diffuse liver metastasis, and the liver metastases significantly reduced in size during the early phase of eribulin treatment, when they developed pseudocirrhosis. Subsequently, the patients had poor prognoses.
