摘要: The BRAF(V600E) mutation is commonly found in papillary thyroid cancers (PTCs) at different frequencies regions. However, the association between and clinicopathological features Chinese PTC patients unknown. A total of 543 with histologically confirmed were enrolled this study. For BRAF assay, target fragments amplified sequenced an ABI 3500 gene analyzer. In 170 samples (31.3%), was detected. bivariate analysis, showed bilaterality, tumor size, extrathyroidal invasion, lymph node metastases (LNM). multivariate positively related to only size (>1 cm) invasion. addition, analysis also that age diagnosis ( 1 cm) independent predictors for LNM. study, associated worse prognostic factors, including larger extending capsule or region; however, it not predictor
