[A case of secondary sclerosing cholangitis caused by chemotherapy with nab-paclitaxel].

A 73-year-old woman had received 9 months of chemotherapy with nab-paclitaxel for locally advanced breast cancer. During the treatment, she was well and showed no major side effects except for alopecia and arthralgia. The tumor showed a tendency to reduction. However, chemotherapy was discontinued because of liver dysfunction. MRCP and ERCP demonstrated multiple stenoses of the hepatic ducts and the intrahepatic bile ducts. We diagnosed chemotherapy-induced sclerosing cholangitis caused by nab-paclitaxel. Treatment with ursodeoxycholic acid and steroid was ineffective. We added bezafibrate, which resulted in a gradual improvement in liver function. To the best of our knowledge, this is the first reported case of nab-paclitaxel-induced secondary sclerosing cholangitis.
