Abstract
|
|
|
Purpose: Cervical lymphadenectomy is frequently performed in patients with lateral cervical lymph node metastasis to improve regional control of disease. However, there is controversy regarding appropriate levels of the neck that need to be dissected. In particular, the routine dissection of level V remains an annoying and time consuming procedure due to the injury of the spinal accessory nerve.
Methods: To identify clinical and pathological predictors of cervical node metastases to level V in papillary thyroid carcinoma, we analyzed 42 patients who underwent modified radical neck dissection (MRND), which were separately performed by each strict anatomical level. Five patients underwent both MRND, 29 patients received total thyroidectomy with central neck node dissection and MRND at the time of initial operation. Thirteen patients underwent MRND later when lateral neck metastases were found at the follow-up after total thyroidectomy with central neck node dissection.
Results: In our series, 11.9% of neck specimens harbored metastatic thyroid carcinoma at level V. The metastatic rate of level II, III, and IV was 54.7%, 85.7%, and 64.2%, respectively. The presence of level V metastases was not significantly associated with level II, III metastases, age, sex, and histopathologic findings. But, it seemed to be associated with level IV metastases if the proportion of metastasis of level IV exceeded 50%.
Conclusion: Cervical node metastasis seems to be associated with level IV metastases if the proportion of metastasis of level IV exceeds 50%.
