BACKGROUND: Pulmonary metastasectomies are performed for a variety of @entity5 , though few reports have examined their merit for @entity135 . This study examined the relationship between clinical and pathological characteristics and survival after resection of lung metastases of these @entity5 . METHODS: Between 1986 and 2013, 34 @entity1 presenting with pulmonary metastases of primary @entity135 underwent surgical resections at our institution. We retrospectively analyzed their clinical and pathological characteristics and the @entity1 ' survival after metastasectomy in search of adverse prognostic factors. RESULTS: The primary sites of @entity5 were: the tongue in eight @entity1 , the pharynx and salivary glands each in seven, the larynx in five, and miscellaneous sites in seven @entity1 . @entity957 ( @entity957 ) was present in 19, @entity2347 in 10, and other diagnoses in five @entity1 . The median disease-free interval (DFI) between the initial surgery and the metastasectomies was 40 months. The overall five-year survival rate was 57.9%, and median survival time was 77 months. By single variable analysis, a DFI of  <=26 months, age >= 60 years, and histology of @entity957 were predictors; by multiple variable analysis, a short DFI (P = 0.018) and older age (P = 0.046) remained independent predictors of poor clinical outcomes. CONCLUSIONS: Young age and a long DFI are factors in favor of pulmonary metastasectomy after surgical treatment of primary @entity135 .
