Spontaneous regression of lung metastases after transarterial chemoembolization for hepatocellular carcinoma

Spontaneous regressions of primary and/or metastatic lesions have been rarely reported in hepatocellular carcinoma (HCC). Herein, we report the case of a 71-year-old man with HCC, focusing on shape changes of lung metastases over time. Lung metastasis of HCC was histologically diagnosed by percutane...

Description
Summary:Spontaneous regressions of primary and/or metastatic lesions have been rarely reported in hepatocellular carcinoma (HCC). Herein, we report the case of a 71-year-old man with HCC, focusing on shape changes of lung metastases over time. Lung metastasis of HCC was histologically diagnosed by percutaneous computed tomography (CT)-guided needle biopsy after the treatment of primary HCC lesion. Lung lesions had been observed on enhanced contrast computed tomography for >3 years without any local or systemic treatment for them. During this period, treatments including surgical procedure for relapsed bladder cancer and transarterial chemoembolization for HCC were performed. Metastatic lung lesions immediately regressed after these treatments. Therefore, accumulation of such cases may help elucidate spontaneous regression mechanisms in primary HCC or its lung metastases.
