Lapatinib is an inhibitor of the tyrosine kinases of human epidermal growth factor receptor type 2 (HER2) and epidermal growth factor receptor type 1, with clinical activity in HER2-positive metastatic breast cancer. We present here a 60 year-old patient with metastatic breast cancer who presented with jaundice and increased serum aminotransferase levels and who had been treated with lapatinib for the previous 14 days. Laboratory tests excluded other causes of acute liver injury. Liver biopsy revealed lesions compatible with drug-induced hepatotoxicity. Bilirubin and liver enzymes returned to normal within three months of lapatinib discontinuation. Lapatinib should be included among the causes of drug-induced hepatitis.
拉帕替尼是一种人表皮生长因子受体 2(HER2)和表皮生长因子受体 1 的酪氨酸激酶抑制剂,在 HER2 阳性转移性乳腺癌中有临床活性。我们在此介绍一位 60 岁的转移性乳腺癌患者,该患者出现黄疸和血清转氨酶水平升高,并且在过去 14 天内接受了拉帕替尼治疗。实验室检查排除了其他急性肝损伤的原因。肝活检显示符合药物性肝毒性的病变。停用拉帕替尼后三个月内胆红素和肝酶恢复正常。拉帕替尼应列入药物性肝炎的病因之一。
