概要 Hepatocellular carcinoma (HCC) with extrahepatic metastasis is rare, and its prognosis is extremely poor. There is no standard treatment for HCC with extrahepatic metastasis. We report a case of abscopal effect in HCC with multiple pleural metastases in a patient who was treated with focal radiotherapy to extrahepatic metastasis, and achieved long-term survival. We performed radiotherapy only to the tumor in inferior vena cava and the proximal pleural tumor. The regimen comprised a total dose of 30 Gy administered in ten fractions to these tumors, followed by 12 Gy administered in four fractions (a total of 42 Gy in 14 fractions) as boost irradiation to the remaining tumor, and a complete regression was achieved. There have been some case reports on abscopal effects in HCC, but no reports on patients with multiple pleural metastases. To our knowledge, this is the first case report on the abscopal effect of focal radiotherapy resulting in complete regression of distant multiple pleural metastases.
