Use of Delphian lymph node metastasis to predict central and lateral involvement in papillary thyroid carcinoma: A systematic review and meta-analysis.

Delphian lymph node metastasis is valuable for predicting central and lateral compartment involvement in patients with PTC. The DLN of PTC patients should be dissected intraoperatively and sent for frozen section consultation. If the result is positive, the CLNs should be thoroughly dissected and the LLNs should be further evaluated.
