Thyroid, 2012
Background: Cervical lymph node metastases from differentiated thyroid cancer (DTC) are common. Thirty to eighty percent of patients with papillary thyroid cancer harbor lymph node metastases, with the central neck being the most common compartment involved. The goals of this study were to: (1) identify appropriate methods for determining metastatic DTC in the lateral neck and (2) address the extent of lymph node dissection for the lateral neck necessary to control nodal disease balanced against known risks of surgery. Methods: A literature review followed by formulation of a consensus statement was performed. Results: Four proposals regarding management of the lateral neck are made for consideration by organizations developing management guidelines for patients with thyroid nodules and DTC including the next iteration of management guidelines developed by the American Thyroid Association (ATA). Metastases to lateral neck nodes must be considered in the evaluation of the newly diagnosed thyroid cancer patient and for surveillance of the previously treated DTC patient. Conclusions: Lateral neck lymph nodes are a significant consideration in the surgical management of patients with DTC. When current guidelines formulated by the ATA and by other international medical societies are followed, initial evaluation of the DTC patient with ultrasound (or other modalities when indicated) will help to identify lateral neck lymph nodes of concern. These findings should be addressed using fine-needle aspiration biopsy. A comprehensive neck dissection of at least nodal levels IIa, III, IV, and Vb should be performed when indicated to optimize disease control.

Introduction: The treatment and particularly the extension of surgical therapy of papillary thyroid carcinoma (PTC) remain still controversial in some issues, especially for the lack of preoperative information or variables that allow predicting the level of aggressiveness of the tumor. Aim of the study: The purpose of the study was to assess the impact of the central node neck dissection (CNND) on surgical outcome and disease free-follow up of PTC-patients operated on at our center by evaluation of postoperative complications (parathyroid and recurrent nerve damage, hemorrhage rates) and pts rates presenting detectable serum Thyroglobulin (TG) or TG-Antibodies (TG-AB) values, at the time of 131 Iodine treatment and subsequently at 6-12 months, combined with neck high-resolution ultrasound (HRUS) The results of a prospective study on 149 pts preoperatively diagnosed and HR-US staged N0-PTC who underwent total thyroidectomy and CNND were compared with the results of a retrospective study on 114 similar postoperatively diagnosed PTC-pts who received total thyroidectomy, without nodes dissection. Materials and methods: 149 patients who underwent total thyroidectomy (TT)+CNND from March 2012 to August 2013 (group-A) and 114 patients who underwent TT from January to December 2011 (group-B) were compared on the following variables: gender, age, histological variant of PTC, tumor size, TNM stage, multifocality, vascular invasion, thyroiditis, expression of BRAF mutation, surgical complications (transient postoperative hypocalcemia and hypoparathyroidism, temporary or permanent dysphonia and hemorrhage), values of TG and anti-TG Ab in suspension or under TSH stimulus, in pre-ablation and on the last clinical and instrumental evaluation of the patient. Statistical analysis was performed using the Student t-test and Fisher. A p value less than 0.05 was considered statistically significant. Results: Comparing the patients of group-A with group-B the following variables present with statistically significant differences: transient postoperative hypocalcemia (group-A 50.3% vs group-B 21.9% , p<0.0001) , association with lymphocitary chronic thyroiditis (group-A 63.1% vs group-B 37.7%, p<0.0001), median postoperative serum TG value (group-A 1,05 ng/L vs group-B 2,4 ng/L , p=0.01), median postoperative anti-TG antibodies value (group-A 903 kU/L vs group-B 118.5 kU/L, p=0.006), median value of anti-TG antibodies at the last follow up after radioiodine therapy (group-A 481,5 kU/L vs group-B 35 kU/L, p=0.0001).
Central neck dissection in differentiated thyroid cancer: technical notes
Acta otorhinolaryngologica Italica : organo ufficiale della Società italiana di otorinolaringologia e chirurgia cervico-facciale, 2014
Differentiated thyroid cancers may be associated with regional lymph node metastases in 20-50% of cases. The central compartment (VIupper VII levels) is considered to be the first echelon of nodal metastases in all differentiated thyroid carcinomas. The indication for central neck dissection is still debated especially in patients with cN0 disease. For some authors, central neck dissection is recommended for lymph nodes that are suspect preoperatively (either clinically or with ultrasound) and/or for lymph node metastases detected intra-operatively with a positive frozen section. In need of a better definition, we divided the dissection in four different areas to map localization of metastases. In this study, we present the rationale for central neck dissection in the management of differentiated thyroid carcinoma, providing some anatomical reflections on surgical technique, oncological considerations and analysis of complications. Central neck dissection may be limited to the compa...
Management of the Neck in Well-Differentiated Thyroid Cancer
Current Oncology Reports, 2020
Purpose of Review In this narrative review, we discuss the indications for elective and therapeutic neck dissections and the postoperative surveillance and treatment options for recurrent nodal disease in patients with well-differentiated thyroid cancer. Recent Findings Increased availability of advanced imaging modalities has led to an increased detection rate of previously occult nodal disease in thyroid cancer. Nodal metastases are more common in young patients, large primary tumors, specific genotypes, and certain histological types. While clinically evident nodal disease in the lateral neck compartments has a significant oncological impact, particularly in the older age group, microscopic metastases to the central or the lateral neck in well-differentiated thyroid cancer do not significantly affect outcome. Summary As patients with clinically evident nodal disease are associated with worse outcomes, they should be treated surgically in order to reduce rates of regional recurrence and improve survival. The benefit of elective neck dissection remains unverified as the impact of microscopic disease on outcomes is not significant. Keywords Lymphatic metastasis. Neck dissection.

Minimally Invasive Thyroid Surgery for Diagnostic Excision of Solitary Thyroid Nodules
Asian Journal of Surgery, 2007
OBJECTIVE: Various techniques for minimally invasive thyroid surgery (MITS), including endoscopic and video-assisted procedures, have now been described. Based on our unit's experience with minimally invasive parathyroidectomy via a lateral incision, a similar technique for minimally invasive thyroid lobectomy has been developed and assessed. METHODS: The last 203 consecutive thyroid procedures using the MITS technique, performed between July 2002 and June 2006, comprised the study group. Inclusion criteria for initial surgery were: initial nodule < 3.0 cm; no preoperative evidence of malignancy; absence of clinical multinodular change. A 2.5cm lateral incision, using a headlight illumination, provided optimal exposure. RESULTS: A total of 202 patients underwent 203 MITS procedures over the 4-year period, with one patient undergoing bilateral MITS. The procedures included 155 thyroid lobectomies and 48 nodule excisions; 31 of the patients underwent a minimally invasive parathyroidectomy (MIP) during which an ipsilateral thyroid nodule was removed. The mean tumour size was 17.3 mm, but the mean size of the thyroid lobe removed was 39.5 mm. Final diagnoses included benign multinodular goitre (26%), follicular adenoma (22%) and carcinoma (20%). The complication rate was low, with one permanent recurrent laryngeal nerve (RLN) palsy (anterior division only) (0.5%), four RLN neuropraxias which recovered (2%), and one haematoma not requiring re-operation (0.5%). The rate of complications was not significantly different from 819 conventional open hemithyroidectomies performed over the same period. CONCLUSION: MITS is a safe and feasible alternative to open thyroid surgery in appropriately selected cases. It offers a valuable option for diagnostic excision biopsy in patients with thyroid nodules demonstrating an "atypical" fine-needle biopsy whilst avoiding the need for a standard cervical "collar" incision.
Cervical neck dissection without drainage in papillary thyroid carcinoma
The Journal of Laryngology & Otology, 2013
Objective:To review the safety of thyroidectomy combined with cervical neck dissection without drainage, in patients with papillary thyroid carcinoma.Materials and methods:Two groups were defined depending on whether cervical neck dissection was or was not performed (groups one and two, respectively).Results:Group one included 153 patients with central neck dissection and 52 patients with central and lateral neck dissection. Group two included 121 patients. Post-operative drainage was not used in either group. Overall, 17 patients (5 per cent) developed post-operative haematoma and/or seroma: 12 patients (6 per cent) in group one and 5 patients (4 per cent) in group two. There were no major bleeding episodes; only minor bleeding or seroma was encountered, not requiring surgical intervention. Overall, 91 per cent of patients had a post-operative stay of 1 day. The number of peri-operative local complications and length of stay did not differ significantly between the two groups.Concl...
Minimally invasive thyroidectomy and the differentiated lesions: the way to follow
European review for medical and pharmacological sciences, 2012
Nowadays, the conventional thyroidectomy may appear an overly aggressive treatment in patients undergoing intervention for small suspicious lesions harboring in low volume glands. In these cases a minimally invasive approach may be a safe and appropriate option. This work aims to evaluate the effectiveness of minimally invasive thyroidectomy in patients indicated to surgery for small lesions with preoperative suspicion of malignancy. 71 patients, undergoing minimally invasive total thyroidectomy as a single procedure between May 2005 and April 2009, were enrolled in this study. They were indicated to surgery for small suspicious or malignant lesions (up to 20 mm lenght by US; cT1 according to UICC 2002) and satisfied the inclusion criteria of minimally invasive thyroidectomy, with gland volume up to 25 ml, no evidence of locally advanced disease and no previous neck surgery. The outcomes were considered in terms of complication rate, postoperative pain, hospitalisation stay, cosmeti...
Is routine central neck dissection necessary for the treatment of papillary thyroid microcarcinoma?
Clinical and …, 2008
ObjectivesIt remains unclear as to whether routine central neck dissection (CND) is necessary when performing surgery to treat patients with papillary thyroid microcarcinoma (PTMC). To determine the necessity for routine CND in PTMC patients, we reviewed the clinicopathologic and laboratory data of the patients of PTMC.MethodsBetween September 2001 and July 2005, 101 patients with PTMC and clinical N0 disease were retrospectively reviewed. The study cohort was devided into groups: the total thyroidectomy plus CND group (the CND group, N=48) and the total thyroidectomy without CND group (the no CND group, N=53). The serum stimulated thyroglobulin (Tg) levels were measured after surgery and prior to radioactive iodine ablation therapy (RAI) and at 6-12 months after RAI. Pathology, the Tg levels and recurrence data were compared between the 2 groups.ResultsCentral nodal metastases were found in 18 of the 48 CND patients (37.5%). The incidence of Tg levels >5 ng/mL at RAI was higher in the no CND patients and in the 18 node-positive CND patients compared with the 30 node-negative CND patients (22-24% vs. 3%, respectively, P=0.020-0.058). The difference when performing a similar comparison using a >2 ng/mL Tg threshold level showed no significance (10-11% vs. 4%, respectively, P>0.1). Two of the no CND patients and one node-positive CND patient had recurrences in the thyroid bed or lateral neck during a mean follow-up of 24 months.ConclusionThe data showed that occult metastasis to the central neck is common in PTMC patients. A CND provides pathologic information about the nodal metastases, and it potentially provides guidance for planning the postoperative RAI. However, the long-term benefit of CND on recurrence and survival remains somewhat questionable.
