Location and causation of residual lymph node metastasis after surgical treatment of regionally advanced differentiated thyroid cancer.

CONCLUSION: Residual nodal metastasis following initial surgical treatment for regionally advanced differentiated thyroid cancer is rather common on highly sensitive 131-I scans with SPECT/CT and is due to both unrecognized nodal involvement preoperatively and incomplete removal of metastatic lymph nodes during compartment-orientated nodal dissection. The surgical management of high-risk DTC should include preoperative imaging to evaluate for nodal metastases in the central and lateral neck and compartment-orientated nodal dissection of involved compartments. Attention should be given to complete dissection in levels VI, III, and II, particularly when dissecting compartments ipsilateral to the primary tumor.
