Risk factors for central XXXX in @entity3557 : A National @entity5 Data Base (NCDB) study.

@entity1 @entity1600 @entity5 @entity3557
BACKGROUND: There is no consensus regarding prophylactic central lymph node dissection (pCLND) in @entity1 with @entity3557 ( @entity3557 ). Identification of risk factors for central @entity1600 (CLNM) in @entity1 with @entity3557 could assist surgeons in determining whether to perform selective pCLND. METHODS: The National @entity5 database was queried from 1998 to 2011 for @entity1 with clinical staging T1-4cN0M0 @entity3557 . All @entity1 underwent near, sub-, or total thyroidectomy with or without pCLND. Univariate and multivariable logistic regressions were performed on the following clinical variables: age, sex, race and @entity5 size as risk factors for pathologic CLNM (pN1a). RESULTS: In 39,562 @entity1 with T1-4cN0M0 @entity3557 , 61% underwent pCLND. @entity1 with age >45  years, African American race, @entity5 size  <=1  cm, unifocal @entity5 , follicular variant @entity3557 , no insurance, and treatment at @entity5 facilities were less likely to have pCLND (P  <  .001). In the pCLND group, 15.6% of @entity1 had CLNM. On adjusted multivariable logistic regression, age  <=45  years, Asian race, male sex, and larger @entity5 were statistically significantly associated with CLNM. CONCLUSION: Age  <=45  years, Asian race, male sex, and larger @entity5 are associated with the presence of CLNM, which allows for selective pCLND in @entity3557 .
