Lymph node staging in patients with clinically negative neck examinations by ultrasound and ultrasound-guided aspiration cytology.

To assess the usefulness of ultrasound and ultrasound-guided fine-needle aspiration cytology in detecting occult cervical lymph node metastases, 107 patients with squamous cell carcinoma of the head and neck, who underwent 132 elective neck dissections, had preoperative ultrasound examination. During the assessment of the last 54 patients, who underwent 70 elective neck dissections, ultrasound-guided aspiration cytology was available. Although ultrasound was able to detect lymph node metastases in the majority of patients, the accuracy of this technique never exceeded 70% (93 of 132 procedures). With ultrasound-guided aspiration cytology, accuracy was 89% (62 of 70 procedures). This latter technique seems to be the modality of choice for the assessment of the clinically negative neck. Its use obviates the need for elective neck dissection, done because of the high risk of occult metastasis.

[Clinicopathological study on patterns of cervical lymph node metastases from squamous cell carcinomas (SCC) of the head and neck].

In order to investigate the patterns of cervical lymph node metastases from head and neck SCC, serial sections were performed on 384 radical neck dissection (RND) specimens. Positive lymph node was found in 60.4% RNDs. The cervical lymph node spread from SCC in the head and neck regions including oral cavity, oropharynx, hypopharynx and larynx has some predictable patterns, i.e., for primary SCC of the oral cavity, the majority of cervical lymph node metastases were clustered at levels I, II and III; and for primary carcinoma of the oropharynx, hypopharynx and larynx, a majority of node metastases were located at levels II, III and IV. The positive lymph nodes mainly distributed at only one level or consecutive levels. The rates of pathologically positive lymph node and extranodal spread grew with the increase of the clinical N-staging. It is suggested that supraomohyoid neck dissection (levels I, II and III) is particularly applicable to carcinomas of the oral cavity, and lateral neck dissction (levels II, III and IV) is applicable to carcinomas of the oropharynx, hypopharynx and larynx in patients with limited (N0 and N1) neck nodules, but for patients with N2 and N3 nodules, RND is neccessary to eradicate the nodal metastases. Moreover, the postoperative radiotherapy is indispensable for ruling out the occult cervical lymph node metastaese in selective neck dissection.

Patterns of nodal metastasis and surgical management of the neck in supraglottic laryngeal carcinoma.

BACKGROUND: Appropriate management of the clinically negative (N0) neck in supraglottic laryngeal cancer continues to be an area of controversy in head and neck surgery. Our treatment policy has been aggressive surgical management even in the clinically N0 neck. METHODS: Between 1971 and 1991, 104 patients had the primary diagnosis of supraglottic laryngeal cancer. Ninety of these patients received their treatment at Roswell Park Cancer Institute and are the subject of this retrospective review. RESULTS: All neoplasms included in this study were squamous cell cancers. The most common subsite involved with tumor in our series was the epiglottis, followed by the aryepiglottic folds and false cords. Supraglottic laryngectomy was performed of 29% of the cases; the remainder received total laryngectomy. Thirty-six percent of the patients had pathologic stage I/II disease, and 64% had stage III/IV. The 5-year survival rates were 100%, 81%, 73%, and 63% for stages I through IV, respectively. Fifty-seven patients had clinically N0 disease at presentation; of these 34 underwent elective neck dissection, and the remaining 23 patients were observed. Of those patients receiving neck dissection, 30% (n = 10) were found to have histologically positive disease, and of the 23 patients observed, 30% (n = 7) had histologically positive regional (neck) disease. Of the 17 clinically N0 and pathologically N+ patients, 82% (14 of 17) had involvement of level I (submandibular triangle), and 100% had involvement of level II. The incidence of bilateral disease in the clinically N0 patient was 44%. There were no local failures. CONCLUSIONS: There is a high incidence of occult regional disease even in early-stage supraglottic squamous cell carcinoma of the larynx. In the surgical management the clinically N0 neck, we presently recommend bilateral neck dissection of levels I through IV to adequately address those regions at highest risk for occult disease.

Neck recurrence in early carcinoma tongue.

OBJECTIVE: To study the efficacy of different locoregional treatment options for tongue cancer in determining the prognosis, with reference to recurrence of disease in neck. METHODS: This is a retrospective analysis of 80 patients with early (T1/T2) carcinoma tongue who had hemiglossectomy with or without neck surgery and radiotherapy for 14 years. RESULTS: Eighty patients were included in this study, 49 (61.3%) men and 31 (38.8%) women; 36 (45%) patients with T1 lesion and 44 (55%) with T2 lesion. Sixty two patients (77.5%) were staged cN0 and 18 patients had a clinically palpable neck nodes (cN+). Thirty seven patients were pathologically negative (pN0), whereas 22 were pathologically positive (pN+) and 21 were not operated so they were staged pathologically (pNx) (undissected necks). Thirty patients received postoperative adjuvant radiotherapy. The median follow-up was 16.5 months with a range of 10-120 months. The over-all rate of recurrence in neck was 32.5% (27 patients). The rate of recurrence was 23% in T1 and 45.8% in T2 lesion (P-value 0.09) without radiotherapy. The recurrence rates with T1 lesion patients who were given adjuvant radiotherapy did not change significantly whereas with T2 lesions the recurrence rate decreased from 45% to 25% in the group without radiotherapy. Recurrence rate was higher in undissected neck as compared to patients who underwent elective neck dissection having radiotherapy and staged pN0 (P-value 0.009) or pN+ (P-value 0.005). Patients having therapeutic neck dissection, on comparison of final pathological node staging (i.e. pN0 or pN+) the rate of recurrence in patients pN+ was 56% and in group with pN0 it was 11%, with (P-value 0.046). CONCLUSION: We did not find any effect of age, gender and surgically resected margins of primary early tongue tumor on recurrence of disease in neck. There was no significant difference between primary tumor stage T1 and T2 lesions on neck recurrence when treated with surgery alone, but adjuvant radiotherapy further reduced the neck recurrence in T2 groups. Adjuvant radiotherapy also showed a significant reduction in recurrence rates in both pN0 and pN+. Undissected necks have higher incidence of neck recurrence than dissected neck irrespective of pathological status of neck metastasis.

Detection and surgical treatment of cervical lymph nodes in differentiated thyroid cancer.

There is considerable controversy regarding the treatment of patients with cervical metastases from differentiated thyroid cancer. Most have papillary carcinoma and the main areas of contention relate to methods of assessment and staging, surgical management and mode of follow up. there is little evidence to support elective anatomical imaging with CT or MRI in those patients with suspected or proven malignancy at the primary site as indicated by fine needle aspiration cytology (FNAC) but who have no clinical evidence of nodal disease. The role of routine ultrasound (US) in the pre-operative assessment of suspected or known malignancy is developing but is largely unproven. When it is performed, high risk areas for metastatic neck disease (levels II-V) should be assessed. Suspicious nodes on US should be further evaluated by FNAC. Suspected or proven neck disease may be further assessed pre-operatively with CT or MRI and then treated surgically. Disease in the central compartment requires a total thyroidectomy and level VI central compartment neck dissection. Suspected or proven lateral compartment cancer should be treated by selective neck dissection (at least levels III, IV, and V) below the accessory nerve. There is no role for 'Berry picking' and clinically node negative high risk patients should have an elective central compartment level VI neck dissection. Sentinel node biopsy lays no role and neither does elective lateral compartment surgery in patients with no clinical or radiological evidence of disease. For follow up, US represents the most sensitive means of detecting neck recurrences and in the presence of an elevated serum thyroglobulin, imaging may also include whole body iodine-131 scanning and anatomical imaging with CT or MRI. The role of PET remains controversial but is likely to develop further as the technique becomes more widely available. In the future, the concentration of patients with this disease in large center can only improve the way we treat differentiated thyroid cancer.

Nodal size of metastatic squamous cell carcinoma of the neck.

The preoperative use of computed tomographic (CT) scanning continues to be the best diagnostic method for preoperative detection of metastatic neck disease. Current accepted criteria for CT diagnosis of nodal disease are not uniform, although nodal size, nodal grouping, and central necrosis correlate strongly with malignancy. To assess the relationship of nodal size and malignancy, a multicenter study was designed to evaluate the nodes from 100 neck dissections. Sixty-nine positive neck dissections were analyzed, and every node was measured. The relationship of central necrosis was also compared with node size. Our results showed that CT scanning continues to provide a reliable picture of the histologic status of lymph nodes. Using the criterion of central necrosis or node size larger than 1 cm, only 7% of necks had nodal disease that would have been missed by CT interpretation. This study supports the continued use of preoperative CT evaluation for metastatic neck disease.

[Cervical metastasis in patients with T2-4 cN0 laryngeal carcinoma].

OBJECTIVE: To study the characteristics of the cervical lymph node metastasis in clinical N0 (cN0) patients with laryngeal carcinoma and its implication in clinical treatment. METHODS: 76 patients with laryngeal carcinomas of T2-4cN0 category were divided into two groups in random: 21(22 sides) radical neck dissection(RND) and 55(60 sides) functional neck dissection(FND) were performed. Lymph nodes were studied histologically according to the levels. RESULTS: On an average, 29.6 lymph nodes were obtained in one side of neck in RND group, and 24.7 in FND group(F = 3.145, P = 0.068). The occult metastasis rates were 33.3% (7/21) in RND group and 34.5% (19/55) in FND group. 25 of 26 patients (96.2%) who had positive nodes involved only the levels II and III. 2130 lymph nodes were obtained in all samples, 59 of 60 positive nodes(98.3%) were located in the level II and III. The 5 and 10-year survival rates of the two groups were 71.4% (15/21), 76.4% (42/55) and 61.9% (13/21), 68.9% (31/45), respectively with no statistical difference(chi 2 = 0.2394, P > 0.5; chi 2 = 0.3143, P > 0.05). Ipsilateral cervical recurrence rates in two groups were 9.5% (2/21) and 7.3% (4/55), respectively with no statistical difference (chi 2 = 0.1059, P > 0.900). 10-year mortalities with negative and positive cervical lymph nodes were 16.7% (7/42) and 62.5% (15/24) respectively, which had statistically difference (chi 2 = 14.4375, P < 0.005). CONCLUSION: The lateral neck (level II, III and IV) dissection may be suitable for the treatment laryngeal carcinoma patients with T2-4cN0.

Tissue-conserving surgery for prognosis, treatment, and function preservation.

OBJECTIVES: To describe an approach based on initial tissue-conserving surgery used to obtain histologically determined prognostic information that has therapeutic implications and the potential to enhance preservation of function. STUDY DESIGN: Analysis of a group of patients with head and neck cancer treated initially with tissue-conserving surgery based on Mohs' histographic sectioning and selected neck dissection to derive histologically determined prognostic information with therapeutic implications and preservation in function. METHODS: This study is primarily based on an analysis of patients from January 1, 1989, through June 4, 1996 assigned to a protocol evaluating resection of oral cavity squamous cell cancer with margin control using Mohs' histographic technique and/or a group of patients with neck assessment of NO on clinical examination who are undergoing supraomohyoid neck dissections. RESULTS: Thirty-three primary tumor resections were performed using the Mohs' technique, and 54% required two or more Mohs' sections before clear histologic margins were obtained following resection based on clinically determined negative margins. There were 44 patients who underwent unilateral or bilateral supraomohyoid neck dissections, and 33% had occult, histologically positive nodes. When compared with the disease of the neck specimens, a preoperative computed tomography scan had a sensitivity of 25%, a specificity of 77%, and an accuracy of 63%. CONCLUSIONS: This report describes the effectiveness of Mohs' histographic sectioning and selective neck dissection as a means of determining prognostic information that can be used to develop a focused and cost-effective treatment program that, along with contemporary reconstructive techniques, provides a potential enhancement of function preservation.

Magnetic resonance imaging in the assessment of cervical nodal metastasis in oral squamous cell carcinoma.

OBJECTIVE: The accurate pre-operative assessment of cervical lymph nodes is a well recognized problem in the management of patients with oral squamous cell carcinoma. Imaging techniques have improved the accuracy of staging but cannot determine if nodal enlargement is due to reactive changes or malignant involvement. We assessed the diagnostic performance of magnetic resonance imaging (MRI) in detecting metastatic disease within the neck in oral cancer patients. MATERIALS AND METHODS: A retrospective study was performed on 58 patients treated for oral squamous cell carcinoma. All patients had pre-operative MR imaging including axial and coronal short tau inversion recovery (STIR) sequences and pre- and post-gadolinium axial T1 weighted sequences. Nineteen patients had bilateral neck dissections giving 77 sides of neck for study. MR images were reviewed for nodal involvement at each anatomical level within the neck and correlated with findings at histology. RESULTS: Twenty-seven of the 77 sides of neck contained histologically positive nodes (35.1%). MRI sensitivity was 66.7% and specificity 68%. There was a false-negative rate of 20.9% and false-positive rate of 47.1%. Some enlarged, histologically positive nodes were not detected by MRI. Furthermore, in five cases the only histological evidence of nodal malignancy was the presence of a micrometastasis (<3 mm tumour deposit). MRI detected two of these. CONCLUSION: MRI lacks sufficient sensitivity and specificity to replace elective neck dissection for both staging and prognostic purposes.

Early supraglottic cancer: how extensive must surgical resection be, if used alone?

OBJECTIVES: Two centre based evaluations of oncologic results of endoscopic resection of supraglottic cancer without post-operative irradiation. PATIENTS AND METHODS: Twenty-six patients with clinical T1 (n=5) or T2 (n=21) primary squamous cell carcinomas of the supraglottic larynx and with N0 (n=24) or N1 (n=2) neck disease were treated by endoscopic supraglottic laryngectomy coupled with neck dissection(s). Endoscopic resection was standardized whereas neck dissections (NDs) varied from classical modified radical ND to selective ND of levels I to IV. RESULTS: Pathologically, three T2 patients were upstaged to T3, four N0 patients to N1 and one N2 patient down-staged to N1. Within an average of 42 months, there were no local failures and only one regional failure. CONCLUSIONS: Endoscopic resection of T1 and T2 supraglottic cancer without post-operative irradiation achieved good oncological results. No patients with lateralized primary cancers were found to have contralateral cancer on pathological evaluation from bilateral dissections.

[Recurrence of cervical lymph node involvement in surgically treated thyroid cancer. Uselessness of routine cervical lymph node excision (medullary carcinoma excluded)].

From 1966 throughout September 1990, 753 patients underwent surgery for thyroid carcinoma, in the same institution, covering all pathological types. Complete follow-up was achieved in 96% of them, being at least 7 years in 50% of cases. 599 (80%) are currently alive. Neck dissection was not routinely done, except for medullary thyroid carcinoma, but rather selectively, if nodes were palpable either pre or intraoperatively, and also (since oct. 1983 i.e. the last 400 cases) if, after routine sampling of mid jugular nodes, frozen sections assessed nodal invasion. On the grounds of this policy, 205 patients underwent unilateral or bilateral neck dissection; 17% of them died during follow-up whereas 5.9% (12 cases) exhibited a cervical nodal recurrence, 6 of them occurring less than two years post-operatively, including 3 medullary thyroid carcinomas. 548 had no neck dissection; 9% died during follow-up whereas 0.9% (5 cases) exhibited a cervical nodal recurrence, 3 of them occurring less than two years post-operatively. Routine neck dissection seems not to be justified in the surgery of non medullary differentiated thyroid carcinoma, in as much as late occurrence of cervical node metastases is uncommon and does not obviously impair life-expectancy.

A conservation approach to pharyngeal carcinoma with advanced neck disease: optimizing neck management.

BACKGROUND: Surgical management of advanced neck disease remains controversial when a conservative approach based on radiotherapy is retained for primary tumors. The objective of this study was to evaluate retrospectively treatment results in pharyngeal cancers presenting with N2-N3 neck disease, using neck dissection followed by radical locoregional radiotherapy (RT) and to compare these results with those obtained in patients treated by radical RT alone. METHODS: From August 1991 to November 1996, 41 patients with carcinomas of the oro- or hypopharynx were staged as T1-T3 N2-N3 M0 (American Joint Committee on Cancer [AJCC] stage IV). Twenty-four patients were treated with neck dissection followed by RT (group 1) and 17 patients with radical RT (group 2) using a progressively accelerated concomitant boost schedule. Chemotherapy was delivered to 6 patients in group 1 and 8 in group 2 partially concomitantly with RT. RESULTS: Three-year actuarial locoregional control was 73% and 55% for groups 1 and 2, respectively (p = .52). The corresponding 3-year actuarial overall survival rates were 37% and 50% (p = .42). Severe postoperative complications were observed after neck dissection in four patients (16%). Acute toxicity during RT was similar in the two groups. Late toxicities were also similar, except for two patients in group 1 who developed severe laryngeal edema. CONCLUSIONS: Neck dissection followed by radical RT to the primary tumor and neck represents a valid treatment option in this subset of patients, allowing good control of advanced neck disease, while at the same time conserving pharyngolaryngeal function. However, for patients who are at high risk of severe postoperative complications, radical RT can be considered a worthy alternative, particularly for oropharyngeal carcinomas.

Extent of lymph node dissection in T3/T4 cancer of the alveolo-buccal complex.

BACKGROUND: Cancer of the alveolo-buccal complex even when locally advanced is amenable to curative resection. However, the extent of lymph node dissection remains controversial. METHODS: A total of 181 patients with T3/T4 cancer of the alveolo-buccal complex who underwent a radical neck dissection (RND) were analyzed retrospectively to determine the incidence and pattern of lymph node involvement and to define the extent of neck dissection required in these cancers. RESULTS: Lymph node involvement was as follows: level I (85%), II (51%), III (19%), IV (18%), V (5%). Levels I and II were most commonly involved (94%). Skip metastases occurred in 13%. Levels IV and V were involved in 2% and 20% when levels I, II, and III were uninvolved and involved, respectively. CONCLUSION: A supraomohyoid neck dissection (SOHD) should be performed and subjected to a frozen section evaluation in every patient. If lymph nodes are negative, then SOHD is adequate. If levels I, II, or III are positive, then a RND should be performed.

Metastasis to the submandibular gland in head and neck carcinomas.

BACKGROUND: The purpose of this retrospective chart review was to determine whether and how the submandibular gland is involved in metastases of squamous cell carcinoma of the head and neck. METHODS: We reviewed the records of all patients for whom pathology specimens were available after neck dissection for primary head and neck cancers at two institutions. RESULTS: One hundred sixty-nine patients were included in the study, 27 underwent bilateral neck dissections, and 196 submandibular glands were resected and sent for pathology. One hundred forty-four glands had normal histologic findings. Normal or benign histologic changes were present in 187 glands. Three submandibular glands showed invasion from a locally involved lymph node, and six had direct extension from a primary lesion. The primary lesions were all ipsilateral to the involved gland and originated from cancers of the floor of the mouth, alveolar ridge, and tongue. No submandibular glands showed pathologic evidence of metastases. CONCLUSIONS: Because the submandibular gland has no intraparenchymal lymph nodes, its involvement in upper aerodigestive tract carcinomas must be through extension from a locally involved lymph node or the primary tumor. Previous work has demonstrated that the submandibular gland can undergo transplantation out of the neck with subsequent reimplantation, as a possible means of protection from the effects of radiation. We demonstrated the submandibular gland to be involved only in cases of ipsilateral oral cavity tumors or metastasis to ipsilateral level I lymph nodes. We conclude that it is oncologically sound to consider transplantation and replantation of the contralateral submandibular gland for patients with head and neck squamous cell carcinoma when level I lymph nodes are unlikely to be involved.

Postoperative radiation for squamous cell carcinoma metastatic to cervical lymph nodes from an unknown primary site: outcomes and patterns of failure.

BACKGROUND: This retrospective study assesses the outcomes and patterns of failure in patients with squamous cell carcinoma metastatic to cervical lymph nodes from an unknown primary site treated with combined surgery and postoperative radiotherapy. METHODS: One hundred thirty-six patients with squamous cell carcinoma metastatic to cervical lymph nodes from an unknown primary source were treated postoperatively with radiotherapy at the University of Texas M. D. Anderson Cancer Center between the years 1968 and 1992. Stage distribution was: N1, 31 patients; N2a, 49; N2b, 25; N2c, 3; N3, 18; and Nx, 10. Thirty-nine patients had excisional biopsies only, 64 patients underwent modified neck dissections, and 33 had radical neck dissections. Extracapsular extension was present in 87 cases. Fifty-nine patients had multiple nodes involved. The median duration of follow-up for surviving patients was 8.7 years. RESULTS: Twelve patients, all with extracapsular nodal disease, developed regional relapse. The 5-year actuarial rates of regional relapse in patients with and without extracapsular nodal disease were 16% and 0%, respectively (p = .004). Nine patients (22%) with extracapsular disease and multiple nodes relapsed compared with three patients (7%) with extracapsular disease and a solitary node (p = .02). None of the patients treated with excisional biopsy and radiotherapy relapsed regionally. No statistically significant relationship between dose, treatment duration, time interval between surgery, and the start of radiotherapy and relapse was detected. The 2-, 5-, and 10-year actuarial disease-specific survival rates were 82%, 74%, and 68%, respectively. Fourteen patients developed cancers in head and neck mucosal sites; six of these cancers were located in unirradiated tissues. CONCLUSIONS: Relapse occurred infrequently in patients treated with excisional biopsies and postoperative radiotherapy. Extracapsular extension and multiple nodes were associated with worse regional control and disease-specific survival. These results appear consistent with those expected for patients with advanced neck disease and a known primary site, and the absence of a primary site should not exclude patients from studies aiming to improve outcomes in patients with extensive neck disease from a head and neck squamous cell cancer. We continue to recommend radiation to the necks and pharyngeal axis for patients suspected of having residual microscopic disease following surgery for squamous cell carcinoma metastatic to the neck from an unknown primary site.

Experience in the surgical treatment of diseases of the thyroid gland.

Over a 7-yr period from January 1967 to January 1974, 141 patients underwent thyroid surgery for various pathology at the Bexar County Hospital - University of Texas Medical School at San Antonio. Of these, 113 patients underwent subtotal thyroidectomy for benign diseases, including 28 of thyrotoxic patients who underwent subtotal thyroidectomy as definitive treatment. In this group of patients special interest and emphasis was placed in the preoperative and intraoperative management of the difficult and complicated hyperthyroid patient. Preoperative treatment was accomplished by the utilization of multiple drug combinations - including antithyroid drugs, adrenergic blocking agents, and iodine - which resulted in significant decrease in preparation time for surgery. Furthermore, this short intensive preoperative management of complicated hyperthyroid patients allowed satisfactory correction of their problems with little or no morbidity which otherwise would have been extremely difficult if not impossible to resolve. At operation, 28 patients were diagnosed to have malignant disease; 23 underwent total thyroidectomy and the other 5 had subtotal thyroidectomy. In addition to total or subtotal thyroidectomy, 23 patients had either classical or modified radical neck dissection including 9 patients who had bilateral neck dissection. The various surgical techniques utilized, the rationale for rapid preoperative preparation of complicated hyperthyroid patients, morbidity, and long-term follow-up are discussed.

Cutaneous head and neck squamous cell carcinoma metastatic to cervical lymph nodes (nonparotid): a better outcome with surgery and adjuvant radiotherapy.

OBJECTIVE: The aim of this study is to report on the experience of treating cutaneous squamous cell carcinoma (SCC) metastatic to cervical (nonparotid) lymph nodes at the Head and Neck Unit, Westmead Hospital, Sydney, Australia. STUDY DESIGN: Retrospective chart review. METHODS: Patients diagnosed with previously untreated metastatic cutaneous SCC to cervical lymph nodes (levels I-V) and treated with radiotherapy, surgery, or surgery and adjuvant radiotherapy were identified. Relapse and outcome was analyzed using Cox regression analysis. RESULTS: Between 1980 and 2000, 74 patients were treated with curative intent. There were 59 males and 15 females, with a median age of 66 (range 37-93) years. Median duration of follow up was 48 (range 12-187) months. Fifty-two were treated with neck dissection and radiotherapy, 13 with neck dissection alone, and 9 with only radiotherapy. Most patients (85%) had an identifiable index lesion. Level I (38%) and II (36%) lymph nodes were the most often involved. In total, 25 (34%) patients developed recurrent disease, predominantly locoregional (22 of 25). Median time to recurrence was 5.2 (2-34.3) months. Increasing nodal size (> or =3 cm) (P =.01), metastatic spread to multiple nodes (P =.05), and the presence of extranodal spread (P =.01) all predicted for worse survival. Patients undergoing combined modality treatment had a lower relapse rate (15%) and a significantly better disease free survival (P =.001) compared with single modality treatment. CONCLUSION: Metastatic cutaneous SCC is uncommon but potentially lethal. Surgery and adjuvant radiotherapy remain the best practice and provide the best chance of achieving locoregional control.

Neck surgery in patients with primary oropharyngeal cancer treated by radiotherapy.

BACKGROUND: The role of neck surgery in node-positive patients whose primary tumors are treated by definitive radiotherapy is controversial. This analysis was undertaken to assess the risk of withholding planned neck dissection in patients who obtain a complete nodal response to irradiation. METHODS: We reviewed the records of 100 patients who presented between 1984 and 1993 with oropharyngeal cancers metastatic to the neck and whose primary tumors were treated by radiotherapy using the concomitant boost regimen. Seventy-five patients had their nodal disease treated definitively by radiotherapy; those who had complete clinical resolution of all nodal disease (62) had no planned surgery, while 13 underwent neck dissection for presumed residual disease. The remaining 25 patients had either node excision (8) or neck dissection (17) prior to radiotherapy. RESULTS: There were 8 cases of isolated neck failure of which 3 occurred in the 62 patients who had no planned neck surgery, 0 in the 13 patients who had surgery for presumed residual (pathologically negative in 7). and 5 in the 25 patients who had initial neck surgery. In those who obtained a complete response to definitive radiotherapy, the risk of neck relapse was unrelated to pretreatment nodal size. CONCLUSIONS: The policy of observation of the neck after complete nodal response to full-dose irradiation is both safe and cost effective. Imaging to confirm the resolution of nodal disease is recommended.
