Predictive value of the Delphian and level VI nodes in papillary thyroid cancer

Abstract

This is the first study to examine the diagnostic accuracy of all level VI lymph nodes in PTC. While, metastatic involvement of all central nodal groups is indicative of further disease, the DLN is the most accurate predictor.

The total number of prelaryngeal and pretracheal lymph node metastases: is it a reliable predictor of contralateral central lymph node metastasis in papillary thyroid carcinoma?

“…In addition, some studies have revealed that prelaryngeal LN involvement was highly predictive of further nodal metastasis to the central and lateral neck compartments [23][24][25]. Prelaryngeal LN positivity was also associated with the number of metastatic nodes and nodal size [26].…”

The significance of Delphian lymph node in papillary thyroid cancer

“…It could be used as a predictor for recurrence or metastasis of thyroid cancer whose predict accuracy was apparently higher than the pretracheal and paratracheal node. 16 His following research in 2009, in which more PTC patients were enrolled, revealed that central node metastasis was an important predictor for recurrence or metastasis of PTC, especially DLN, which was more accurate. In 2012, Woo Woong Kim gathered more cases of PTC with DLN metastasis and found the rate of DLN metastasis was 17.2%.…”

Predictive Factors for Different Subgroups of Central Lymph Node Metastasis in Unilateral Papillary Thyroid Carcinoma

“…However, the process does increase the extent of wounding in PTC patients without the 2 subgroups of LN metastasis. Moreover, it has been reported that the involvement of the prelaryngeal central LN is the most accurate predictor of lateral node disease [30]. …”
