BACKGROUND Hepatoid adenocarcinoma of the lung(HAL) is an extremely rare malignant tumor,and many patients with HAL exhibit high levels of alpha-fetoprotein(AFP) expression.Currently,there is no standardized treatment strategy for advanced HAL and its prognosis is poor.CASE SUMMARY We report a 55-year-old man with unresectable AFP-related HAL.The largest cross-sectional area of the mass in the upper lobe of the left lung at the beginning of treatment was 8.46 cm × 6.53 cm.The patient’s serum AFP level was 9283 ng/m L.The mass increased in size to 8.86 cm × 8.21 cm after two courses of platinum-based combination chemotherapy and immunotherapy,and serum AFP reached its highest level(71232.2 ng/m L).The patient was treated with sorafenib(400 mg twice daily,per os).Forty days later,the mass was reduced to 5.63 cm × 5.29 cm and serum AFP level dropped to 786.8 ng/m L.The patient achieved partial remission for > 9 mo with sorafenib and an excellent biomarker response,as well as survival > 13 mo,which is among the longest reported for unresectable stage IV HAL.CONCLUSION This is the first report to document successful treatment of unresectable AFPrelated HAL with single-agent sorafenib after multiline therapy.
