INTRODUCTION: To analyze the association of clinicopathologic characteristics and treatment modality with survival among adult @entity1 with @entity8 . METHODS: We identified 489 adults diagnosed with @entity8 from the Surveillance, Epidemiology and End Results registry between 1973 and 2011. Cancer-specific survival was estimated using the Kaplan-Meier method and was compared between groups with log rank and Cox models. RESULTS: Median age at diagnosis was 61 years, while median @entity5 size was 11cm. @entity5 histology was @entity1822 in 175, @entity1821 in 100, other subtypes in 129, and unknown in 85 cases. @entity5 stage at diagnosis was nonmetastatic in 322 (67%) and metastatic in 167 (33%) cases. Treatment of nonmetastatic disease was surgical resection in 171 @entity1 , radiation in 24, both in 35, neither in 18, and unknown in 74 cases. Treatment of @entity3 was surgery in 39 @entity1 , radiation in 27, both in 11, neither in 42, and unknown in 48. For nonmetastatic and @entity3 , 5-year @entity5 -specific survival rates were 58% and 16%, respectively. On multivariable analysis, surgery was associated with @entity5 -specific mortality among both @entity1 with nonmetastatic disease (hazard ratio = 0.34; 95% CI: 0.14-0.85) and those with @entity3 (hazard ratio = 0.38; 95% CI: 0.18-0.77). Age, race, @entity5 size, and @entity5 grade were independently associated with @entity5 death in nonmetastatic disease, whereas race and @entity5 histology remained associated with mortality in @entity3 (all P< 0.05). CONCLUSION: Although metastatic @entity8 has an ominous prognosis, durable survival may be achieved for @entity5 . Although we recognize the potential for selection bias, our results suggest an association between surgical resection and decreased mortality for both nonmetastatic and metastatic @entity8 .
