Neck dissection in oral cancer--clinical review and analysis of prognostic factors.

The purpose of this study was to evaluate the oncologic effectiveness of radical and different types of modified neck dissections with preservation of the spinal accessory nerve, internal jugular vein and sternocleidomastoid muscle and to identify prognostic factors for regional control and survival in univariate and multivariate analysis. This retrospective study included 373 patients with squamous cell carcinoma of the oral cavity who underwent 401 neck dissections between January 1986 and December 1997 at the Department for Oral and Maxillofacial Surgery, Hanover Medical School. The actuarial neck control rate after 5 years was estimated with 87%. Neck failure occured only within the first 2 years after neck dissection. The number of positive nodes, macroscopic extracapsular spread, peeling off metastases from carotid artery and cranial base and preoperative radiochemotherapy were significant prognostic factors. Grade of metastases, microscopic extracapsular spread, lymphangiosis carcinomatosa and postoperative radiation showed no prognostic significance. The comparison of neck failures after radical and modified neck dissection demonstrated a tendency to improved regional control after radical neck dissection with increasing extent of neck disease.

Neck dissection for surgical treatment of lymphnode metastasis in papillary thyroid carcinoma.

In papillary thyroid carcinoma lymphnode metastases at presentation do not seem to adversely affect survival, but do increase the risk of loco-regional tumor recurrence. The value of systematic versus selective lymphadenectomy is far less standardized, whereas the role of postoperative radioiodine in preventing either nodal recurrence or cancer death remains controversial. Clinical data of 36 N+ patients with papillary thyroid carcinoma who had undergone from 1990 to 1996 ipsilateral or bilateral neck dissection were retrospectively reviewed, to analyse the value of systematic lymphadenectomy. In our series of 50 extensive lymph node dissections (levels 2-6), the number of metastases in each specimen (mean value: 5) and the incidence of multiple level metastases (36%) were high. In 37.5% of the metastases at level 6 and in 11.1% at level 4, coexisting nodal involvement at level 2 was observed, without metastasization at intermediate levels. Multiple levels metastases and skip metastases were present in at least one third of the patients and could be excised only performing a complete dissection of the levels 2-6. Extra-capsular spread was found in 56% of the specimens. In 64.3% of these cases a functional neck dissection was performed. A modified radical or radical neck dissection was carried out in the other 35.7% of the cases. These patients received modified radical neck dissection (functional dissection with sacrifice of internal jugular vein) in 60% of the cases and radical neck dissection in the other 40%. In papillary thyroid carcinoma extensive lymphnode dissection at presentation has been stated to offer no advantage versus selective lymphadenectomy, causing increased morbidity. However, experienced surgeons report a low incidence (less than 5%) of accessory spinal nerve and cervical plexus permanent sequelae after functional neck dissection. In our opinion, patients with cervical lymph node metastases require a complete loco-regional neck dissection. Systematic lymphadenectomy, performed by lateral neck plus upper anterior mediastinal dissection, can yield a high disease-free survival. Moreover, this can limit the overall radio-iodine therapeutic dose and the risk of de-differentiation of recurrent tumor to the anaplastic type in patients with a long-term and near normal life-span.

Reconstruction of spinal accessory nerve after radical neck dissection.

Resection of the spinal accessory nerve in cases of radical neck dissection often causes considerable damage to the function of the shoulder girdle; it leads to limitation of the motion of the upper limb and pain in the shoulder girdle. It seems a sensible compromise to reconstruct the spinal accessory nerve in one-stage operation with radical neck dissection, which can often prevent extensive atrophy of the trapezius muscle, with a resultant improvement in the chance of successful rehabilitation. The technique of the operation is described: after completion of radical neck dissection, in one-stage operation an autogenous nerve transplant from the n. auricularis magnus is sewn onto the central and peripheral stumps of the spinal accessory nerve, which are protected by a "vein-muff" and the fascia of the muscle. After such spinal accessory nerve reconstruction, subjective complaints and objective symptoms were much milder in 6 patients than in the control group, which consisted of 10 patients who underwent a similar operation but without spinal accessory nerve reconstruction.

Microsurgical neck dissection for occultly metastasizing medullary thyroid carcinoma. Three-year results.

BACKGROUND: Medullary thyroid carcinoma (MTC) metastasizes early into the regional lymph nodes, but distant metastases occur late. Modified radical neck dissection might improve the treatment results for occultly metastasizing MTC. METHODS: The authors report 23 patients after a minimal follow-up of 2 years (median, 36 months). There were 11 female and 12 male patients. The mean age was 43 years (+/- 13 years). The surgical technique included the meticulous dissection of all compartments of the neck, resulting in a unilateral or bilateral modified radical neck dissection with the complete removal of the lymphatic and fatty tissue between important anatomical structures. The surgical boundaries extended cranially to the mastoid, caudally to the brachiocephalic vein involving a transcervical mediastinal dissection, and laterally to the edge of the trapezoid muscle. Ten patients were treated bilaterally and 13 patients unilaterally. RESULTS: The basal calcitonin values of 18 of the 23 patients were postoperatively normalized with 4 patients having normal basal and pentagastrin-stimulated calcitonin levels. Five patients with persistently elevated basal serum calcitonin values had a marked reduction of the postoperative calcitonin levels compared with their preoperative concentrations. However, in these five patients histologic abnormalities precluded a surgical cure. The permanent complication rates were tolerable (4 of 33 neck dissections). CONCLUSIONS: The microsurgically extended neck dissection can reduce basal and pentagastrin-stimulated serum calcitonin values to normal levels even after long intervals following primary thyroidectomy.

Bilateral chylothorax following radical neck dissection.

Bilateral chylothorax as a complication of radical neck dissection is extremely rare, but it is potentially serious and sometimes fatal. We found only 14 cases reported in the English literature. Here, we report a case of bilateral chylothorax following right modified and left radical neck dissections that was successfully treated with conservative management.

Functional neck dissection for treatment of recurrent branchial remnants.

OBJECTIVE: To evaluate the role of functional neck dissection for treatment of cervical branchial remnants that are recurrent after previous surgical intervention. DESIGN: A retrospective review was undertaken of six patients undergoing functional neck dissection for excision of recurrent branchial anomalies treated over an 18-year period. SETTING: Academic tertiary referral medical center. PARTICIPANTS: Six patients with recurrent branchial cysts, sinuses, or fistulas. Each participant previously had undergone between one and 14 ineffective surgical procedures. INTERVENTION: Each patient was treated by functional neck dissection. OUTCOME MEASURES: Clinically noted complications and recurrences. RESULTS: There were no major complications. Minor complications included one postoperative wound infection and one transient spinal accessory nerve paresis. There were no recurrences. CONCLUSIONS: Functional neck dissection is a safe and effective procedure for surgical management of recurrent cervical branchial remnants.

Modified radical neck dissection. Terminology, technique, and indications.

The terminology relating to the various modifications of radical neck dissection is loose and confusing. A simple system of nomenclature has been suggested which allows specification of the node levels dissected and the structures preserved. A technique of modified neck dissection, which excludes dissection of the posterior triangle and spares the sternocleidomastoid muscle and spinal accessory nerve, has been described. We believe this operation is appropriate when local disease is advanced and clinically uninvolved neck nodes are likely to harbor occult metastatic disease, when resection of the primary tumor is through the neck, or when clinical disease in the neck is minimal. Patients with multiple palpable nodes, patients with nodes larger than 3 cm in diameter, patients with disease in the posterior triangle, and patients in whom radiotherapy to the neck has failed may be better served by radical neck dissection.

Modified radical neck dissection and minimal invasive tumor surgery in the middle of split course of concomitant chemoradiotherapy of advanced HNSCC.

OBJECTIVE: The effectiveness of modified radical neck dissection with concomitant chemoradiotherapy in patients with N2/3 advanced head and neck cancer was evaluated. STUDY DESIGN AND SETTING: Retrospective study of 35 patients treated at the University Hospital, Medical University, Innsbruck. The treatment consisted of a split course radiation up to 70 Gy with concomitant chemotherapy with Mytomicin C and 5-fluorouracil. Neck dissection and/or tumor resection was performed between the two cycles of radiation and chemotherapy. RESULTS: The 2-year progression-free survival was 64%, locoregional control 92% and overall survival 55. Observed toxicities included mucositis (grade 3, 35%; grade 4, 16%), neutropenia (grade 4, 28%), and thrombocytopenia (grade 4, 26%). No complications related to modified radical neck dissection were observed. CONCLUSION: Intermittent neck dissection was highly effective in controlling the neck disease. Mitomycin C-based chemoradiotherapy for treatment of locally advanced cancer seems to be an option to cisplatin-based regimens.

Indications for bilateral modified radical neck dissection in patients with papillary carcinoma of the thyroid.

HYPOTHESES: After subtotal thyroidectomy with modified radical neck dissection of the affected side, nodal recurrence at the contralateral cervical side indicates a poor prognosis for patients with papillary thyroid cancer. Bilateral modified radical neck dissection is beneficial for patients at high risk for contralateral nodal recurrence. DESIGN AND SETTING: Retrospective study of patients with papillary cancer who were treated surgically from January 1, 1970, through December 31, 1995, at the Noguchi Thyroid Clinic and Hospital Foundation, Beppu, Japan. PATIENTS: Patients (N = 1776) had primary tumors greater than 10 mm in maximum diameter and underwent thyroidectomy and ipsilateral modified radical neck dissection with curative intent. RESULTS: Thirty-two patients (1.8%) developed contralateral lymph node metastases during the mean follow-up period of 12.1 years. The risk factors for contralateral nodal recurrence were male sex, large primary tumor, tumor extension over the isthmus, extracapsular adhesion or invasion to surrounding tissues, and the presence of gross nodal metastasis at initial surgery. These patients had a greater number of distant metastases (31.1% vs 0.7%; P<.001) and a lower 10-year survival rate (83.7% vs 99.3%; P<.001) than patients without nodal recurrence. CONCLUSION: Bilateral modified radical neck dissection should be considered for patients with papillary carcinoma who show risk factors for contralateral nodal recurrence, as it could prevent a second operation and may improve their outcome.

The effect of neck dissection on human fat transport.

This study examines the effect of neck dissection and thoracic duct ligation on lipid metabolism. Included were 23 patients undergoing neck dissection with thoracic duct ligation. The results showed a temporary reduction in lipid metabolism in approximately half the patients who had a left neck dissection. This effect subsided within 6 months, possibly because of the development of alternative lymph channels. The reduction in fat metabolism in selected cases may have therapeutic effects on patients with morbid hypertriglyceridemia or those who receive chemopreventive regimens. To the best of our knowledge, no similar studies have been reported heretofore in humans.

A new shoulder orthosis for paralysis of the trapezius muscle after radical neck dissection: a preliminary report.

Despite recent advances using more conservative approaches, standard classical radical neck dissection is still one of the most frequently performed procedures in head and neck cancer patients who have advanced metastatic neck disease. The trapezius muscle paralysis following division of the spinal accessory nerve results in severe pain and cosmetic disturbance related to malalignment of the shoulder joint. The objective of this study is to report our results with a newly developed orthosis to prevent and correct shoulder dysfunction following standard radical neck dissection. Thirty-four patients who underwent standard radical neck dissection as a part of their surgical treatment from 1997-2002 were rehabilitated by the shoulder orthosis. Beginning 2 weeks after surgery, the patients were allowed to use their orthosis. By using a standard questionnaire, the pain and activity scores were recorded at the 1st, 3rd, 6th and 12th months postoperatively. Six patients were excluded from the study, of whom two succumbed to their disease and four discontinued the use of the orthosis. Of 28 patients included in the study, 20 (72%) were completely pain free within 3 months following the surgery. Four patients (14%) noted their pain level as tolerable, and four patients (14%) reported no considerable gain in the pain threshold and/or physical activity levels. Despite the fact that the active abduction range increased only 5 to 20 degrees , the relief of pain and improved malalignment of the scapula and consequently clavicle and humerus led to functional gains, which increased the patients' endurance. At the end of the study, 23 patients (82%) were able to return to their previous jobs or activity levels. Current preliminary reports suggest that this orthosis can be recommended to prevent significant disability in patients with trapezius palsy due to ablative cancer surgery or other reasons.

Functional neck dissection: cure and functional results.

In this study, the cure and functional results of 133 functional neck dissections performed between 1992-1997 in Erciyes University Medical Faculty were evaluated. The overall recurrence rate was three per cent. This rate was 1.4 per cent for elective functional neck dissections and five per cent for curative functional neck dissections. Electromyographic studies showed that there was severe neurogenic deficit in the trapezius muscle of seven patients (12.5 per cent), and in the sternocleidomastoid muscle of 12 patients (21.4 per cent) among 56 randomly selected patients. In all cases, the flow rate and diameter of the internal jugular vein was found to be normal by Doppler ultrasonography. The results of this study showed that functional neck dissection is a reliable technique for obtaining a high cure rate and functional results.

Neck dissection with or without postoperative radiotherapy in supraglottic carcinomas.

A retrospective review of 302 previously untreated patients with primary supraglottic carcinoma was undertaken to ascertain the efficacy of postoperative radiotherapy. The 302 patients underwent a total of 383 functional neck dissections and 45 classic radical neck dissections. Pathological examination revealed nodal involvement in 117 patients (39%). In the histologically N0 group, the incidence of contralateral neck recurrence when a unilateral neck dissection and postoperative radiotherapy were carried out was 8%, rising 21% when no postoperative radiation was given. There was no difference in the ipsilateral recurrence rate in the N0 group, radiated patients (3%) and nonradiated patients (2%). Similar figures were found in the N1 group. Bilateral functional neck dissection in histologically N0, N1, and N2 necks had similar recurrence rates with or without radiotherapy. Distant metastasis appeared in 10% of N0 patients and in 35% of N3 patients. Patients who received postoperative radiotherapy showed a significantly higher rate of distant metastasis (21%) than patients who did not (8%). The number of involved lymph nodes had no relevance both in neck recurrence and distant metastasis.

Recurrence of carcinoma of the oral cavity, oropharynx and maxillary sinus after radical neck dissection.

Cervical recurrence was studied in 63 patients who had undergone radical neck dissection for the treatment of carcinoma of the oral cavity, oropharynx and maxillary sinus. Over the whole series, recurrence occurred in 17 patients (27%). The rate of recurrence did not decrease in patients who remained free of carcinoma at the primary site, but was significantly lower in patients in whom elective neck dissection was performed than in those who were treated by therapeutic or secondary neck dissection. With the exception of two patients, cervical recurrence was associated with the presence of metastatic lymph nodes. Although the rate of recurrence was not affected by the number of metastatic lymph nodes, it was very high (80%) in patients having metastatic lymph nodes with histological evidence of extra-nodal spread. The results indicate that elective treatment by irradiation or surgery may be needed to reduce cervical recurrence because of a high tendency of carcinoma of the oral cavity and adjacent regions to metastasize.

Antibiotic prophylaxis in clean neck dissections.

This study was designed to evaluate the effects of a prophylactic antibiotic regimen on the incidence of wound infection after clean neck dissections. A prospective series of 57 patients undergoing clean neck dissections with the use of perioperative ampicillin-sulbactam for 24 hours was compared with an historical control group of 51 patients undergoing clean neck dissections with no perioperative antibiotic use. The outcome variable was the incidence of post-operative wound infection. The two groups were similar for factors reported to influence the rate of post-operative wound infection. Wound infection occurred in one patient (1.7 per cent) in the study group and in seven patients (13.3 per cent) in the control group, the difference was statistically significant (p = 0.02). These data suggest that the use of a perioperative antibiotic for 24 hours in patients undergoing clean neck dissection results in significant reduction in the incidence of post-operative wound infection.

Neck dissection with and without radiotherapy: prognostic factors, patterns of recurrence, and survival.

A group of 179 patients who had 205 neck dissections between 1979 and 1984 has been reviewed to assess the influence of adjuvant radiotherapy on survival. Lymph nodes were histologically involved in 91 of 107 radical neck dissections (85 percent) and 55 of 98 modified neck dissections (56 percent). Eighty-two patients received adjuvant radiotherapy of 5,000 rads or more. Patients with involved nodes had significantly lower survival rates than those with uninvolved nodes. Among patients with involved nodes, survival was significantly lower when two or more nodes were involved, when there was nodal involvement at multiple levels, or when extracapsular spread was present. Adjuvant radiotherapy was associated with a reduced recurrence rate in the ipsilateral neck but the incidence of distant metastases was higher. When patients with involved nodes were subgrouped according to prognostic factors, the survival of irradiated patients was improved only in the highest risk group, but this was not statistically significant. When radiotherapy is added to neck dissection for treatment of cervical metastases it can be expected to reduced ipsilateral neck recurrence and prevent relapse in the contralateral neck. Improved survival may depend on an ability to detect and treat occult distant metastases.

Impact of bilateral neck dissection on recovery following supraglottic laryngectomy.

Previously reported data from our institution has led us to perform bilateral neck dissections for therapeutic as well as staging advantages for horizontal supraglottic laryngectomies. Concern over the possibility of increased morbidity associated with simultaneous bilateral neck dissection prompted this retrospective review of patients with supraglottic laryngectomy who were treated with either unilateral (46 patients) or bilateral (23 patients) neck dissection. No significant differences were found in morbidity when patients were evaluated for transfusion rate, cervical wound drainage, need for tracheotomy, oral diet, or duration of hospitalization. Significant differences were noted in surgical operating time, eg, it took 100 minutes longer to perform bilateral dissections, and slight increases were noted in estimated blood loss and fluids given intravenously. No significant differences were noted in the percentage or type of postoperative complications. It seems that bilateral neck dissection in conjunction with supraglottic laryngectomy does not increase postoperative surgical morbidity and may actually avoid complications associated with postoperative radiation therapy in patients with supraglottic laryngectomy.

Incidence of shoulder pain after neck dissection: a clinical explorative study for risk factors.

BACKGROUND: It is the purpose of this study to determine the incidence of shoulder pain and restricted range of motion of the shoulder after neck dissection, and to identify risk factors for the development of shoulder pain and restricted range of motion. METHODS: Clinical patients who underwent a neck dissection completed a questionnaire assessing shoulder pain. The intensity of pain was assessed using a visual analog scale (100 mm). Range of motion of the shoulder was measured. Information about reconstructive surgery and side and type of neck dissection was retrieved from the medical records. RESULTS: Of the patients (n = 177, mean age 60.3 years [SD, 11.9]) 70% experienced pain in the shoulder. Forward flexion and abduction of the operated side was severely reduced compared to the non-operated side, 21 degrees and 47 degrees, respectively. Non-selective neck dissection was a risk factor for the development of shoulder pain (9.6 mm) and a restricted shoulder abduction (55 degrees ). Reconstruction was risk factor for a restricted forward flexion of the shoulder (24.5 degrees ). CONCLUSIONS: Shoulder pain after neck dissection is clinically present in 70% of the patients. Non-selective neck dissection is a risk factor for shoulder pain and a restricted abduction. Reconstruction is a risk factor for a restricted forward flexion of the shoulder.
