Region VI lymph nodes dissection in treatment of 38 cases with cN0 papillary thyroid carcinoma

Abstract

Objective To discuss the significance of region Ⅵ lymph nodes dissection in treatment of patients with clinical cervical nodes negative(cN0)papillary thyroid carcinoma(PTC).Methods Clinical data of 38 cases of cN0 PTC treated with region Ⅵ lymph nodes dissection were retrospectively analyzed.The related literature was reviewed.The cervical nodes dissection scope and the key operation points in treatment of cN0 PTC were discussed.Results No permanent recurrent laryngeal nerve injury or parathyroid damage happened.14 cases(36.84％)had occult lymph node metastasis to region Ⅵ lymph nodes.After more than 5 years of follow-up,all the cases had excellent life quality.3 cases(7.89％)were found lymph node metastasis to lateral cervical region and they were given functional neck dissection.No recurrence or metastasis occurred to the 3 cases during more than 2 years of follow-up.Conclusion Region Ⅵ lymph node dissection in treatment of cN0 PTC is safe,reliable,and with less complications.
