Programmed death-1 inhibitor for occupational intrahepatic cholangiocarcinoma caused by chlorinated organic solvents.

Highlight Tanaka and Kubo reported the first case of recurrent occupational cholangiocarcinoma treated with programmed death-1 inhibitor. A programmed death-1 inhibitor was administered every 2 weeks for para-aortic lymph node metastasis after curative hepatectomy. After seven cycles of administration, positron emission tomography demonstrated diminished lymph node size without ¹⁸ F-fluorodeoxy glucose uptake.
