Pediatric XXXX : outcomes and survival predictors in 2504 surgical @entity1 .

@entity3557 @entity1 @entity259 @entity5
OBJECTIVE: To evaluate outcomes and predictors of survival of pediatric @entity259 , specifically @entity3557 . METHODS: SEER was searched for surgical pediatric cases ( <=20 years old) of @entity3557 diagnosed between 1973 and 2011. Demographics, clinical characteristics, and survival outcomes were analyzed using standard statistical methods. All papillary types, including follicular variant, were included. RESULTS: A total of 2504 cases were identified. Overall incidence was 0.483/100,000 @entity1 per year with a significant annual percent change (APC) in occurrence of 2.07  % from baseline (P  <  0.05). Mean age at diagnosis was 16 years and highest incidence was found in white, female @entity1 ages 15-19. @entity1 with @entity5 sizes  <1  cm more likely received lobectomies/isthmusectomies versus subtotal/total thyroidectomies [OR  =  3.03 (2.12, 4.32); P  <  0.001]. @entity1 with @entity5  >= 1  cm and lymph node-positive statuses [OR  =  99.0 (12.5, 783); P  <  0.001] more likely underwent subtotal/total thyroidectomy compared to lobectomy/isthmusectomy. Tumors  >= 1  cm were more likely lymph node-positive [OR  =  39.4 (16.6, 93.7); p  <  0.001]. Mortality did not differ between procedures. Mean survival was 38.6  years and higher in those with regional disease. Disease-specific 30-year survival ranged from 99 to 100  %, regardless of @entity5 size or procedure. Lymph node sampling did not affect survival. CONCLUSIONS: The incidence of pediatric @entity3557 is increasing. Females have a higher incidence, but similar survival to males. Tumors >= 1  cm were likely to be lymph node-positive. Although @entity5 >= 1  cm were more likely to be resected by subtotal/total thyroidectomy, survival was high and did not differ based on procedure.
