Cytomorphological factors and BRAF mutation predicting risk of lymph node metastasis in preoperative liquid-based fine needle aspirations of papillary thyroid carcinoma.

OBJECTIVE Preoperative fine needle aspiration biopsy (FNAB) has become the initial diagnostic method for papillary thyroid carcinoma (PTC). Identification of cytomorphologic factors predicting lymph node metastasis (LNM) is clinically important for determining the appropriate treatment regimen due to the high rate of lymph node involvement in PTC at the… CONTINUE READING
