[Neck lymph node dissection in squamous cell carcinoma originating in the head-and-neck area; the significance for the prognosis].

Neck dissection has a therapeutical as well as a prognostic relevance with respect to regional recurrence and distant metastases. Between January 1973 and July 1986 576 neck dissections in 511 patients (396 men, 115 women, among whom 486 with squamous cell carcinoma of the head and neck, and 14 with neck metastases of an unknown primary tumour) were performed at the department of Otolaryngology-Head and Neck Surgery of the Free University Hospital, Amsterdam. Patients with tumour at the margins were excluded. Recurrence-free curves were calculated according to Kaplan-Meier and the log rank test was used to test the differences. All patients underwent a comprehensive neck dissection and were irradiated postoperatively when three or more tumour-positive nodes or extranodal spread were reported by the pathologist. Endpoint for analysis was occurrence of an ipsilateral neck recurrence or of a distant metastasis. Figures were corrected for a simultaneous recurrence at a higher level. A total of 29 neck recurrences (7.2%; n = 523) and 26 distant metastases (10.7%; n = 281) were demonstrated in the 5-year follow-up period. The number of positive nodes was of prognostic significance for both events (p = 0.039 and p = 0.0027). Extranodal spread was shown only to increase the incidence of distant metastases (p = 0.017), whereas its prognostic value with regard to recurrence in the neck was nullified by the strict institution of postoperative radiotherapy. It is recommended to give radiotherapy to patients with two positive nodes and possibly to every patient with a histopathologically positive neck.(ABSTRACT TRUNCATED AT 250 WORDS)

Feasibility and cost-effectiveness of sentinel lymph node radiolocalization in stage N0 head and neck cancer.

OBJECTIVES: To determine the feasibility of sentinal lymph node (SN) radiolocalization and to assess the cost-effectiveness of the SN navigation surgery strategy in patients with stage N0 squamous cell carcinoma (SCC) of the head and neck. Patients Eleven consecutive patients with stage N0 SCC of the head and neck. METHODS: Head and neck lymphoscintigraphy was performed 2 hours after the injection of technetium Tc 99m tin colloid or phytate. A handheld gamma probe was used to detect the SN before and directly after making a skin incision. Nodes were evaluated histopathologically for micrometastasis. To determine the expected cost savings, a decision tree sensitivity analysis was designed based on the 2 competing strategies: ipsilateral neck dissection vs SN navigation surgery. The costs referred to billed costs based on the Japanese national insurance reimbursement system. RESULTS: The sensitivity of SN navigation surgery in our series was 100% (11/11) on a patient-by-patient basis and 94% (17/18) on a node-by-node basis. Micrometastasis was found in 36% (4/11). Assuming the micrometastasis prevalence, sensitivity, and specificity of navigation surgery for detecting SN to be 30%, 90%, and 100%, respectively, the decision tree sensitivity analysis showed that introduction of SN navigation surgery in place of ipsilateral neck dissection would yield cost savings of $1218 (US) per stage N0 patient in Japan and avoid 7 surgical deaths per 1000 patients who are supposed to undergo neck dissection in the neck dissection strategy. Break-even point analysis for the SN navigation surgery strategy showed that the threshold value required more than 41 patients for the savings to begin to accrue. CONCLUSION: Our results indicate that SN navigation surgery using radiolocalization is feasible and cost-effective, based on decision tree sensitivity analysis, in patients with stage N0 SCC of the head and neck.

[Detection of the sentinal node in squamous-cell carcinoma of the oral cavity and oropharynx. Preliminary study].

INTRODUCTION: The sentinel lymph node is defined as the first relay of the lymphatic drainage of the tumor. Isotopic detection of the sentinel lymph node and absence of its metastatic invasion should theoretically be predictive of total drainage of the tumor. The goal of this study was to evaluate sentinel lymph node detectability by lymphoscintigraphy in N0 and/or N1 squamous-cell carcinoma of oral cavity and oropharynx and to determine its negative predictive value. MATERIAL AND METHOD: Lymphoscintigraphy was used for sentinel lymph node detection. The procedure required peritumoral injection of technicium-labeled colloids to enable anatomical and cutaneous location of the sentinel lymph node. A one-way Tyco-Mallinckrodt probe was used for intraoperative detection of the sentinel lymph node. This prospective study included 21 patients with N0 or N1 squamous-cell carcinoma of the oral cavity and the oropharynx. The surgical attitude based on T and N was not modified in this prospective study without direct individual benefit for the patient. Neck dissection was achieved without difficulty. RESULTS: The sentinel lymph node was identified in 20 out of 21 subjects. The sentinel lymph node was not identified in one patient with recurrence T2N0M0 squamous-cell carcinoma of the oropharynx radiated 3 years earlier. The percentage of false-negatives was 12.5% (1 false-negative out of 8 positive patients), giving a sensibility of the detection method of 87.5% (IC (95%)=[47.35-99.68]). This false-negative patient had a T3N0M0 squamous-cell carcinoma of the oropharynx with a sentinel lymph node removed in territory III. Neck dissection revealed 1 N + R- in the sub-mandibular territory associated with 27 N-R-. The probability of not finding a metastatic node at neck dissection when the sentinel lymph node is not metastatic (negative predictive value) was 92.3% (12/13) (IC (95)=[63.97-99.81]). The specificity of the method was 100%, as was the positive predictive value, because no sentinel node was diagnosed positive wrongly on frozen sections among patients without true histological node metastasis. DISCUSSION: For routine care of patients with squamous-cell carcinoma of the oral cavity and the oropharynx detection of the sentinel lymph node is proposed primarily for patients with T1T2N0 staging. Larger tumors can modify the architecture and flow within the lymphatic ducts, and consequently even the concept of a sentinel lymph node. Systematic neck dissection is required or T3T4, even when N0. Our series of T1T2N0 tumors is too small to enable statistically significant conclusions. A low level of false-negative in a larger series would be necessary to propose this technique instead of convention neck dissection for T1T2 tumors of the oral cavity and oropharynx.

A rare malignancy of the parotid gland: oncocytic carcinoma.

Oncocytic carcinomas are uncommon; they represent 11% of all oncocytic salivary gland neoplasms, 0.5% of all epithelial salivary gland malignancies and 0.18% of all epithelial salivary gland tumors. A 65-year-old woman was admitted to our ENT clinic with a history of a painless left preauricular mass. No lymph node was palpable on either side of her neck. Computed tomography demonstrated a 3 x 3-cm solid lesion in the left parotid gland. As oncocytes and atypical cells were seen at the cytologic examination of a fine-needle aspiration biopsy, this finding suggested a malignant epithelial tumor. Total parotidectomy by preserving the facial nerve was performed. The result of the pathologic examination was oncocytic carcinoma regarding histopathologic and immunohistochemical findings and especially the invasive growth pattern. We preferred a close follow-up to an elective neck dissection, and reserved the neck dissection for a recurrence. The prognosis of oncocytic carcinomas is not well known because of their low incidence. Further investigation of the prognosis of patients with oncocytic carcinoma of the parotid gland is warranted as more cases are reported.

Radical external beam radiotherapy for 333 squamous carcinomas of the oral cavity--evaluation of late morbidity and a watch policy for the clinically negative neck.

BACKGROUND AND PURPOSE: The aims of this study were to examine local control/morbidity for all cases and a 'watch policy' for the node-negative neck. PATIENTS/METHODS: 333 patients with squamous cell carcinoma of the oral cavity were treated with a short radical radiotherapy regime to the primary site and involved lymph node groups at the Christie Hospital, Manchester, between 1980 and 1987. Only 10 of 278 node-negative patients received elective neck node irradiation. RESULTS: Actuarial cancer-free survival and local control rates at 5 years for the whole group were 55% and 61%, respectively. Control at the primary site was adversely related to increasing T-stage, node positivity and bone involvement at presentation. Osteonecrosis was seen in 14 (5.9%) of 237 cases without bone involvement at presentation. Taking all patients, late morbidity (non-healing soft tissue injury or bone necrosis) was seen in 45 patients (13.6%) at a median time of 21 months from treatment. The factors contributing to late morbidity were: (1) bone involvement at presentation, (2) synchronous MTX chemotherapy, (3) the contribution of scattered radiation from elective neck treatment, (4) increasing radiation dose, (5) increasing target volume for doses less than 55 Gy and (6) dental extractions. Eighty-four (31%) patients who were initially node-negative developed disease in the untreated neck during follow-up. Salvage neck dissections controlled neck disease in half of the node-only recurrences (21/42 cases). CONCLUSION: These results have influenced our treatment policy, with lowering of the primary tumour dose in some cases and addition of elective neck irradiation for T2-T4 No patients.

Simultaneous medullary and papillary thyroid carcinoma with lymph node metastasis in the same patient: case report and review of the literature.

We report a rare case of simultaneous medullary thyroid carcinoma on the left thyroid lobe with lymph node metastasis and papillary thyroid cancer on the right thyroid lobe. The 55-year-old woman was diagnosed with medullary thyroid carcinoma after left hemithyroidectomy for goitre. Completion thyroidectomy, central neck dissection and left modified neck dissection revealed the presence of papillary carcinoma on the right side. The extreme rarity and interesting pathological features are discussed and we raise the question of whether the finding of another thyroid cancer on the opposite side was coincidental or from possible activation of a common tumorigenic pathway for both follicular and parafollicular thyroid cells.

Pancreatic cancer with metastasis to the larynx.

A laryngeal metastasis from pleomorphic carcinoma of the pancreas is described. The patient was a 70-year-old male. The tumour was located on the right margin of the epiglottis. Bilateral neck lymph node metastases were also found. The patient underwent supraglottic laryngectomy, right radical neck dissection and left suprahyoid neck dissection. Following surgery, the patient's general condition deteriorated day by day, and one month after the surgery he died. The autopsy findings demonstrated a big mass of cancer in the pancreatic tail, multiple lymphatic metastases, carcinomatous peritonitis, and possibly a lymphatic spread of the pancreatic cancer to the larynx.

Malignant ameloblastoma: classification, diagnostic, and therapeutic challenges.

Ameloblastoma is a benign odontogenic neoplasm of the mandible and maxilla that rarely exhibits malignant behavior. We report the case of an aggressive malignant ameloblastoma of the mandible that presented with an unusual multiphasic, histologic pattern. Initial fine needle aspiration and radiographic findings showed features consistent with a benign, fibro-osseous lesion. However, aggressive growth and the association of enlarged submandibular lymph nodes suggested a more malignant potential. Treatment consisted of an angle-to-angle composite mandibular resection, right modified neck dissection, left functional supraomohyoid neck dissection, and anterior chin skin resection with iliac crest osteocutaneous free flap reconstruction. Microscopic evaluation showed primarily malignant ameloblastoma without cellular atypia and extensive fields of fibro-osseous tissue with smaller fields of clear cell odontogenic tumor. This multiphasic, histologic arrangement may explain the perplexing preoperative microscopic diagnosis, suggesting a benign fibro-osseous lesion. Of the lymph nodes analyzed, one from the right submandibular triangle exhibited metastatic, benign-appearing ameloblastoma without fibro-osseous or clear cell features. The absence of cellular features of malignancy in the tumor mass and lymph node metastasis suggest that the lesion should be classified as malignant ameloblastoma rather than ameloblastic carcinoma or odontogenic carcinoma. A malignant ameloblastoma with all 3 of the aforementioned microscopic features has not been previously reported. We review the classification of epithelial odontogenic malignancies. Lesions showing multiphasic patterns can create diagnostic dilemmas and may require extensive surgical sampling and/or removal to establish an accurate diagnosis.

Skin metastasis: an unusual localization from laryngeal carcinoma.

Skin metastasis from laryngeal carcinoma is rare and indicates a poor prognosis. A case of laryngeal carcinoma with unusual metastasis to the skin of the hand is reported. The patient underwent total laryngectomy, left radical neck dissection, and right functional neck dissection. After the operation, the patient received radiotherapy. In the postoperative 18th month, a mass was observed in the left hand. It was found to be a metastatic tumor from laryngeal carcinoma, histopathologically as well as immunohistochemically. Metastatic potential in malignant neoplasms is generally correlated with reduced cellular adhesiveness. We investigated the expression of the vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9), and E-cadherin. Interestingly, the immunohistochemical expression characteristics of such an aggressive tumor were not positive.

Squamous cell carcinoma of the lip.

We reviewed 39 cases of squamous cell carcinoma of lip from 53 consecutive patients with carcinoma of the lip. The retrospective review includes age, location, risk factors, TNM classification, histologic differentiation, treatment methods, recurrent disease, site of recurrence, and follow-up status. Results reveal prognosis is related to original tumor size, local recurrence, and presence of cervical metastasis. Aggressive surgical treatment is recommended for identifiable poor prognostic lesions and includes surgical excision, prophylactic suprahyoid neck dissection, and possible radical neck dissection.

Cancer of the scalp.

Carcinomas on the scalp have a tendency to recur following traditional treatment. Their management is often difficult because of the extent of the tumor and the unique anatomy of the area. In order to maximize cure rates for complicated carcinomas, Mohs micrographic surgeons and other surgical specialists have formed interdisciplinary treatment teams. Resection of bone, parotid/facial nerve dissection, and neck dissection are often necessary. Interdisciplinary cooperation in the treatment of skin cancer leads to maximal utilization of expertise and is a major advance in cancer treatment.

[Our experience in the study and treatment of medullary carcinomas of the thyroid. Apropos of 2 familial cases].

Between July 1976 and July 1984, 1106 cold thyroid nodules have been operated on UCL. Teaching Hospital; 128 were diagnosed as carcinoma (11,5%) and 15 were diagnosed as medullary carcinoma of the thyroid gland (1,3% of all the cold nodules and 12% of all carcinomas of the thyroid). This article presents the case of two families exhibiting a characteristic clinical history of Medullary Carcinoma of the thyroid or CMT. The authors describe briefly the clinical signs; they point out that it is absolutely necessary to ask for a blood calcitonine level control in case of cold thyroid nodule or cervical lymphadenopathie. Once the diagnosis of Medullary Carcinoma of the thyroid gland is reached, screening of the Family, at least the first degree relatives should be undertaken, in order to reveal subclinical cases, which could be detected by laboratory investigations at an early subclinical stage. The treatment of the CMT is always surgery; it consists of total thyroidectomy with a modified neck dissection or a radical neck dissection, if lymph nodes are more than 3 cm or are fixed. Any way the recurrent nerve nodes have to be looked for, and if positive a Mediastinal lymph node dissection should be carried out. A control of the calcitonine hormone blood level should be asked for twice a year to detect any metastases or recurrence.

Results of integrated management of supraglottic carcinoma.

Between January 1957 and June 1974, 173 patients with carcinoma of the supraglottic larynx were treated by an integrated approach at the University of California in San Francisco. The policy was to use radiotherapy or surgery alone for Stage I and II disease, radiotherapy combined with either supraglottic laryngectomy or total laryngectomy for resectable Stage III and IV disease, and radiotherapy alone for advanced unresectable disease. Control of the disease in the primary site was achieved in 92% of T1a, 88% of T1b, 80% of T2, 79% of T3 and 56% of T4 lesions. Of the 36 patients with late Stage I and resectable Stages III and IV disease treated by combined preoperative radiotherapy and supraglottic or total laryngectomy, the primary lesion was controlled in 33 (92%). Recurrent disease in the primary site after radiotherapy alone, when detected early, was usually controlled by subsequent surgery, whereas recurrent disease after surgery was not controlled by radiotherapy. Preservation of a functioning vocal apparatus was achieved in 44% of the patients whose primary lesion was controlled. Control of cervical lymph node metastasis was achieved in 71% of N1, 38% of N2, and 25% of N3 disease. No disease recurred in the radically dissected neck which received preoperative radiotherapy. Radiotherapy also reduced the incidence of subsequent neck disease in patients without cervical lymph node metastasis initially from 23% to 14%.

The 11th nerve syndrome. Accessory nerve palsy or adhesive capsulitis?

The 11th nerve syndrome classically involves the majority of patients undergoing neck dissections even when the accessory nerve is preserved. A preliminary analysis of our data of 31 of 44 patients who underwent neck dissections from a prospective study showed numerous findings of shoulder disability that are not attributable to accessory nerve palsy but are well described by the syndrome of adhesive capsulitis of the glenohumeral joint. At 1 month postoperatively, although accessory nerve palsy symptoms were common, adhesive capsulitis symptoms were significant. At 6 months, the frequency of accessory nerve palsy symptoms was less as the accessory nerve had begun to recover. At 12 and 18 months, when most of the accessory nerves had recovered, the accessory nerve palsy symptoms were comparatively uncommon while the adhesive capsulitis symptoms predominated as the remaining symptoms of the 11th nerve syndrome. We propose that adhesive capsulitis is a principal component of the 11th nerve syndrome that can significantly compound the morbidity of a neck dissection even when the accessory nerve recovers. We also propose that adhesive capsulitis accounts for the persistence and variability of shoulder symptoms after neck dissection that cannot be attributed to trapezius muscle dysfunction.

Incidence of regional recurrence guiding radicality in differentiated thyroid carcinoma.

Total thyroidectomy has become the routine procedure for treatment of differentiated thyroid carcinoma. However, the necessity of unilateral or bilateral neck dissection is far less standardized. Our usual procedure has been to perform a routine neck dissection in T4 tumors and in all other tumor stages only in the presence of positive diagnostic or intraoperative findings. The results concerning regional tumor recurrence in cervical lymph nodes subsequent to thyroidectomy are studied and discussed. Between April 1986 and December 1992 a group of 252 patients were operated on for differentiated thyroid carcinoma (DTC) (176 papillary, 76 follicular). Postoperative treatment included radioiodine therapy as a rule in all patients more than stage T1, and follow-up encompassed thyroglobulin measurements, cervical ultrasonography, and radioiodine scintigraphy. After a mean follow-up of 6.9 years, 77 (31%) of the patients underwent reoperation because of regional tumor recurrence [46 of 176 (26%) papillary, 31 of 76 (41%) follicular]. In papillary thyroid cancer a significant difference could be demonstrated between patients with thyroidectomy only versus thyroidectomy plus neck dissection in all tumor stages (T2, 13 of 29 (45%) versus 1 of 34 (3%); T3, 10 of 13 (77%) versus 4 of 11 (36%); T4, 6 of 8 (75%) versus 6 of 18 (33%) (p < 0.0001). Similar results could be achieved for follicular thyroid cancer, showing statistical significance with regard to operative procedure (p < 0.009). Our experience demonstrates a positive correlation of regional tumor recurrence with increasing tumor stage for both histologic tumor types. The high rate of regional recurrence justifies a more radical approach, including neck dissection at the initial operation. The impact on survival, however, must be proved by further evaluation.

Internal jugular vein patency in patients undergoing microvascular reconstruction.

The objective of this study was to determine the incidence of internal jugular vein thrombosis in patients undergoing free flap reconstruction and simultaneous neck dissection. Patients underwent Doppler ultrasound examination of their internal jugular veins on postoperative days 1 and 7 after functional neck dissection and free flap transfer. Long-term follow up was obtained at a minimum of 3 months. The incidence of internal jugular vein thrombosis in patients undergoing free flap reconstruction with simultaneous neck dissection is similar to that of patients undergoing just neck dissection. A significant number of these veins recanalize and have excellent long term patency. There does not seem to be a correlation between venous thrombosis and free flap survival.

[Reconstruction of mandibular defect caused by resection of oral carcinoma with pectoralis major myocutaneous flap and ti-plate system].

OBJECTIVE: To investigate the clinical effect of the pectoralis major myocutaneous flap and Ti-plate system in repairing mandibular defects caused by resection of oral carcinoma. METHODS: From November 2001 to February 2003, 32 patients with mandibular defect caused by resection of oral carcinoma were treated. Combined radical neck dissection with resection of gingival and mandible was performed on 11 patients with carcinoma of the lower gingival, combined radical neck dissection with glossectomy and mandibulectomy on 13 patients with carcinoma of tongue, combined radical neck dissection with resection of floor of mouth and mandible on 4 patients with carcinoma of floor of mouth, and combined radical neck dissection with resection of cheek and mandible on 4 patients with carcinoma of buccal mucosa, respectively. The defects of mandible were associated with soft-tissue component, the sizes of defect ranged from 5.5 cm x 7.6 cm to 8. 2 cm x 10.5 cm. The defects were reconstructed with 6 cm x 7 cm to 9 cm x 10 cm pectoralis major myocutaneous flaps and Ti-plate system. The effect was studied retrospectively. RESULTS: Thirty-two cases were followed for 2-19 months; 29 cases of flaps survived and 3 cases of flaps partly necrosed (10% or less of the skin paddle). The appearance of face was satisfactory in 27 patients, and slight deformity of face was observed in 5 patients. The occluding relation and masticatory function were recovered well. Opening mouth extents ranged from 2.7 cm to 3.4 cm. No temporomandibular arthrosis relating to operation was found in all cases. CONCLUSION: A combination of the pectoralis major myocutaneous flap and Ti-plate system is an ideal method for reconstruction of mandible defects associated with soft-tissue component after radical operation of oral carcinoma.

The problem of neck relapse in early stage supraglottic cancer--results of different treatment modalities for the clinically negative neck.

We reviewed the records of patients with Stage I and II epidermoid carcinoma of the supraglottic larynx treated at the Memorial Sloan-Kettering Cancer Center (MSKCC), New York, and at the Rotterdam Radio-Therapeutic Institute (RRTI), The Netherlands, between 1965 and 1979. At the MSKCC the treatment modality of choice for the primary tumor as well as for the neck had been surgery; of the 79 patients treated by surgery an elective neck dissection was performed on 31 patients. At the RRTI, however, the initial treatment for the primary tumor and the neck is radiation therapy. One-hundred and one patients were treated of whom 79% (80/101) had radiation therapy to the primary tumor as well as to both sides of the neck. This paper focuses on the problem of relapse in the neck, thus comparing patients treated in two large cancer centers by different treatment philosophies, that is elective neck dissection on one side of the neck versus elective radiation therapy to both sides of the neck. Twenty-nine percent of the patients from MSKCC (23/79) relapsed in the neck. The relapse rate was identical between the patients who did not have an elective radical neck dissection, and those who did. Among the patients who relapsed in the neck 65% (15/23) have died of the cancer, while among those who did not, none has died of supraglottic larynx cancer. Twenty-three percent (23/101) of the patients of the RRTI relapsed in the neck. Those who received radiation therapy to the primary tumor only relapsed regionally in 38% (8/21); treatment of both sides of the neck reduced the incidence of nodal recurrence to 19% (15/80). The majority of patients who relapsed in the neck eventually died of the cancer, that is 57% (13/23). Data from both institutions once again demonstrate the impact on survival of a relapse in the neck. Best strategies for decreasing the relapse rate in the neck are discussed; the conclusion was reached that, so far, elective radiation to both sides of the neck is the preferable treatment.
