Chen J, et al. - In papillary thyroid carcinoma (PTC) patients, researchers investigated whether there was an association between central cervical lymph node metastasis (CLNM) and ultrasound (US) features, immunohistochemical factors and BRAF^V600E mutation by analyzing data from 225 consecutive patients who had undergone surgery. Risk factors for central CLNM were PTC ≤10 mm, microcalcification, internal vascularity, capsule contact or involvement and BRAF^V600E mutation. The study findings suggested that the risk model might be beneficial in the treatment planning and management of patients with PTCs.
