[Value of jugulo-omohyoid lymph nodes in predicting lateral cervical occult metastasis in patients with papillary thyroid carcinoma].
Objective:To investigate the value of jugulo-omohyoid lymph nodes (JOHLN) in predicting occult lateral cervical lymph node metastasis in patients with papillary thyroid carcinoma (PTC).Methods:The clinicopathological data of 136 out of 2 100 PTC patients, who had a high risk of lateral neck lymph node metastasis and treated by us from January 2010 to December 2015, were retrospectively analyzed. Super selective neck dissection (SSND, level Ⅲ and Ⅳ)was performed and JOHLNs were sent for frozen section in all the 136 cases. The clinicopathological data was analyzed and the significance of JOHLN in predicting lateral cervical LNM was calculated using the SPSS software package.Results:Of the 136 patients, total thyroidectomy was performed in 76 cases (55.9%) and unilateral lobectomy plus isthmus was performed in the other 60 cases (44.1%). SSND was performed in 72 patients (52.9%), level Ⅱ-Ⅳ dissection in 15 (11.0%), and level Ⅱ-Ⅴ dissection in 49 (36.0%). According to the pathological results, 38 patients were pN0(27.9%), 18 (13.2%) were pN1a and 80 (58.8%) were pN1b. The lymph node metastasis(LNM) rates at level Ⅱ-Ⅵ were 19.9%, 43.4%, 42.6%, 2.9%, and 59.6%, respectively. The sensitivity, specificity and accuracy of JOHLN in predicting lateral neck metastasis were 58.8%, 62.9%, and 76.7%, respectively. The rates for predicting level Ⅱ metastasis were 81.5%, 43.2%, and 59.4%, respectively. None of the patients died in the follow-up. Only 1 recurrence was found in level Ⅱ and regional control was achieved after level Ⅱ and Ⅴ dissection.Conclusions:JOHLN has a high accuracy for predicting lateral cervical lymph node metastasis and high sensitivity for level Ⅱ metastasis. For patients with high risk of lateral cervival metastasis, super-selective neck dissection including level Ⅲ and Ⅳ can confirm the stage and reduce the risk of reoperation. Dissection for level Ⅱ, Ⅲ, and Ⅳ is recommended.
