Lv T, et al. - A retrospective analysis was performed to determine the clinical factors that could be indicators for malignancy in nodules in the contralateral thyroid lobe, which could aid the clinician in selecting the appropriate operative approach. Malignancies were found in the contralateral lobe in 47% of patients. This finding was correlated with multifocal primary carcinoma involvement, capsular invasion, a history of Hashimoto's thyroiditis, central lymph node metastases, and BRAF mutation.
