Objective. Few reports have examined the treatment outcomes of surgery for metastases of head and neck cancer to the lung. Methods. We reviewed the surgical and oncological results of 38 patients who underwent lung resection for pulmonary metastasis from head and neck cancer from 2005 to 2015. Results. Seventeen patients with pharyngeal cancer, eight with laryngeal cancer, and eight with tongue cancer were included. Of these patients, 28 had greater than stage III disease. Twenty-six patients developed pulmonary metastasis within two years of the initial treatment of head and neck cancer. The mean disease-free interval (DFI) from the treatment for head and neck cancer was 17 months (range: 1-61 months). All patients underwent lung resection via the thoracoscopic approach. Thirty-three patients achieved complete resection. The median survival period was 43 months (range 1-119 months) after lung resection for pulmonary metastasis. The 5-year overall survival rate for all these patients was 49.1%. A DFI < 17 months (p=0.0409) and incomplete resection (p<0.0003) tended to result in an extremely poor prognosis. Conclusion. If complete resection is possible, aggressive surgical treatment for head and neck cancer metastases to the lung may improve the prognosis.
