Risk stratification for lateral involvement in papillary thyroid carcinoma patients with central lymph node metastasis

To effectively predict lateral neck lymph nodes (LLN) metastasis in papillary thyroid carcinoma (PTC) patients with central lymph nodes (CLN) invasion, and devise targeted treatment strategies. Four hundred and thirty-four PTC patients with CLN metastasis from two medical centers were retrospectively analyzed. A new statistical model was established for predicting LLN involvement in these patients to guide lymph nodes management strategies....
