BRAF and metastatic malignant neoplasm in the lymph nodes: BL BRAF V600E mutations were more likely to be detected if metastases occurred only in the liver (OR 15.87; P < 0.0001) or in more than one organ including the liver (OR 16.12; P < 0.0001), or if lymph node metastases were present (OR 6.11; P = 0.018).
