Prognostic Factors after Resection of Lung Metastasis from Head and Neck Cancer / 日本農村医学会雑誌

We retrospectively evaluated 21 patients with resected lung metastases from head and neck cancers (oral cavity, pharynx, larynx, and others) in our department between April 2009 and December 2016. The 5-year overall survival after lung resection was 56.7％ and median survival time was 21 months, which was good compared with findings in the literature. Tumor size of lung metastatic lesion≥2.0cm was a significant prognostic factor (p＝0.0157). No independent prognostic factors were identified in multivariate analysis. Aggressive resection was suggested to contribute to prognosis, especially for pulmonary metastasis with diameter<2.0cm. These findings may have wide implications for social medicine.
