A 70-year-old man was diagnosed with multiple lung metastases from hepatocellular carcinoma, and lenvatinib was initiated. Three months later, the response was progressive disease. Sorafenib therapy as a second-line drug was started. Three months later, the lung metastases had shrunk. After the sorafenib failure, the patient received regorafenib treatment for six months until failure. After the regorafenib failure, sorafenib rechallenge therapy as a fourth-line treatment was initiated. The sorafenib rechallenge, which continued for two months, induced a partial response. Sorafenib after lenvatinib failure and sorafenib rechallenge may be a good option, but further prospective studies are needed.
