Reproducible complete remission of advanced hepatocellular carcinoma with sorafenib in combination with clopidogrel.

We present a 57-year-old Caucasian man with hepatocellular carcinoma (HCC) twice achieving complete remission with reduced dose sorafenib. His initial diagnosis of HCC rapidly improved with sorafenib and he achieved a complete biochemical and radiographic response within 7 months. Remission lasted only 5 months but we noted that the timing of his relapse was immediately after he incidentally discontinued clopidogrel. It was restarted and within 5 months of restarting clopidogrel he once again achieved complete remission. The course of his remission was followed and temporal association of sorafenib remission with use of clopidogrel was observed. 2014 BMJ Publishing Group Ltd.
