UNASSIGNED: Thyroid extracts were first used to treat @entity1 with metastatic @entity0 over a century ago. Since then, a number of studies have investigated the association between @entity1374 and @entity0 . The presence of antibodies to thyroid peroxidase (TPOab) was recently reported to be associated with improved outcome in these @entity1 . The aim of the present study was to evaluate the association between TPOab positivity and clinicopathological characteristics in @entity0 @entity1 . The study included 318 newly diagnosed cases of @entity0 treated at Ondokuz Mayis University Hospital, Samsun, @entity233 , between 2008 and 2012. Serum thyroid-stimulating hormone, free @entity1954 and free @entity1955 levels were measured at the time of diagnosis. Of the 318 @entity1 , 253 were considered to be TPOab-negative (TPOab  <=34 IU/ml) and 65 TPOab-positive (TPOab >34 IU/ml). No cases with distant @entity3 were found in the TPOab-positive group. However, 20 (7.9%) of the 253 @entity1 displayed distant @entity3 in the TPOab-negative group (P=0.01). Therefore, TPOab positivity was found to be associated with a lower incidence of @entity3 in @entity0 @entity1 .

Antithyroid peroxidase antibody positivity is associated with lower incidence of @entity3 in XXXX .
