Management of the Neck in Well-Differentiated Thyroid Cancer.

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. 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.

Immune cell infiltration in head and neck squamous cell carcinoma and patient outcome: a retrospective study.

BACKGROUND: Human papillomavirus (HPV) prevalence in oropharynx squamous cell carcinoma (OPSCC) is on the rise. HPV-linked OPSCCs represent a distinct clinical entity with a better treatment response and patient survival compared to tumors not linked to HPV. An emerging role in treatment response has been attributed to immune cell infiltration in human tumors. In this study, we investigated immune cell infiltration in human SCC of the head and neck region and its relation to overall survival after treatment with surgery (with or without radiotherapy) or concomitant chemo (or cetuximab)-radiotherapy. MATERIALS AND METHODS: Paraffin-embedded tumor samples of 136 patients with SCC of the larynx, hypopharynx, oral cavity and oropharynx were processed for immunohistochemical detection of CD3+ T-cells, CD8+ cytotoxic T-cells, CD20+ B-cells and CD163+ M2 macrophages within the tumor infiltrated area. Clinico-pathological data were analyzed as a function of tumor location and p16-status. Immune cell infiltration was represented as stained area on the whole tumor infiltrated area, compared for the different tumor locations and correlated to patient survival. RESULTS: Patients with oropharynx tumors expressing significant p16 levels (p16-sg) had a 5-year overall survival of 85% compared to 43% for patients with no significant p16 (p16-ns) expression (HR: 0.3 - 95% CI: 0.1-0.6). Median immune cell infiltration (T- and B-lymphocytes) was significantly elevated in p16-sg oropharyngeal tumors, compared to p16-ns oropharyngeal tumors and to all other head and neck tumor locations. No difference in CD163+ macrophage infiltration was observed across the different patient groups. In the whole population, a high infiltration by CD3+ T-lymphocytes was associated to a significantly (p = .03; HR: 0.6, 95% CI: 0.4-0.97) better overall survival. CONCLUSION: Oropharynx cancer with significant p16 expression showed an increased overall survival and elevated T- and B-lymphocyte infiltration, which suggests a prognostic relevance of immune cell infiltration.

Quality assurance in head and neck surgery: special considerations to catch up.

PURPOSE: Quality assurance is much more difficult to achieve in surgical oncology than in medical oncology and radiotherapy where doses are standardized and toxicities are well-classified. To better define what is required in surgery, we analyzed recent articles addressing the point in head and neck surgery. RESULTS: The surgical report should match with the pathological description of the resected specimen with accurate delineation of the margins, number and level(s) of lymph nodes (capsular rupture if any). Complications (minor and major) should be standardized and meticulously recorded; as well as comorbidities and patient status. The acuity of the procedure should be defined by metrics collected in check-lists. Age > 60 years, male gender, tumor site and T4 stage, neck dissection(s), flap reconstruction, alcohol and tobacco consumption, are acknowledged risk factors for more complications and longer hospital stay (or readmission). NEEDS: Randomized controlled trials should be designed adopting the consolidated standards of reporting trials (CONSORT). Training young head and neck surgeons should encompass formation in designing, conducting and interpreting clinical trials.

Impact of prophylactic central neck dissection on oncologic outcomes of papillary thyroid carcinoma: a review.

Prophylactic neck dissection (PND) for papillary thyroid carcinoma (PTC) is controversial. Our aim was to assess current levels of evidence (LE) according to the Oxford Centre for Evidence-based Medicine ( http://www.cebm.net/?O=1025 ) regarding the oncologic benefits of PND. Data were analyzed via MEDLINE keywords: PTC, differentiated thyroid carcinoma, PND, central lymph node metastases, central compartment, recurrence-free survival. There was conflicting evidence regarding the rate of reoperation for recurrence, with some studies showing a lower rate after PND with increased recurrence-free survival and a higher rate of undetectable pre- and post-ablation thyroglobulin levels (LE 4), whereas other studies did not show a difference (LE 4). Only one study (LE 4) showed improved disease-specific survival with PND. PND may improve recurrence-free survival, although this is supported by only a low LE. Current recommendations can only be based on low-level evidence.

The role of neck dissection in squamous cell carcinoma of the head and neck.

ORIGINAL STATEMENT: Lymph node metastases in the neck are a major prognostic factor in patients with head and neck squamous cell carcinoma (HNSCC). Assessment and treatment of lymph nodes in the neck are of utmost importance. Inappropriate management of lymph node metastases can result in regional failure. Radical neck dissection has been and is still considered the "gold standard" for the surgical management of lymph node metastases of HNSCC. However, the philosophy of treatment of the neck has evolved during the last decades. Surgeons progressively realized that extensive neck dissections were associated with a higher morbidity but not always with a better oncologic outcome than more limited procedures. Today, a comprehensive therapeutic approach of the neck is multidisciplinary, taking into account the patient's quality of life without jeopardizing cure and survival. A better understanding of the patterns of lymph node metastasis promoted the use of selective neck dissection in selected patients. Sentinel lymph node biopsy is a reliable diagnostic procedure for staging the neck in node-negative early oral cavity squamous cell carcinoma. With increasing use of chemoradiation in locally advanced HNSCC, paradigms are evolving. Currently, there are strong arguments supporting the position that neck dissection is no longer justified in patients without clinically residual disease in the neck.

The controversy in the management of the N0 neck for squamous cell carcinoma of the maxillary sinus.

Squamous cell carcinoma (SCC) of the maxillary sinus is a relatively rare disease. As the reported incidence of regional metastasis varies widely, controversy exists as to whether or not the N0 classified neck should be treated electively. In this review, the data from published series are analyzed to decide on a recommendation of elective treatment of the neck in maxillary SCC. The published series consist of heterogeneous populations of different subsites of the paranasal sinuses, different histological types, different staging and treatment modalities used and different ways of reporting the results. These factors do not allow for recommendations based on high levels of evidence. Given this fact, the relatively high incidence rate of regional metastasis at presentation or in follow-up in the untreated N0 neck, and the relatively low toxicity of elective neck irradiation, such irradiation in SCC of the maxillary sinus should be considered.

Carotid body paragangliomas: a systematic study on management with surgery and radiotherapy.

The definitive universally accepted treatment for carotid body tumors (CBT) is surgery. The impact of surgery on cranial nerves and the carotid artery has often been underestimated. Alternatively, a few CBTs have been followed without treatment or irradiation. The goal of this study is to summarize the existing evidence concerning the efficacy and safety of surgery and external beam radiotherapy (EBRT) for CBT. Relevant articles were identified using strict criteria for systematic searches. Sixty-seven articles met the criteria which included 2,175 surgically treated patients. On the other hand, 17 articles including 127 patients treated with EBRT were found. Long-term control of the disease was obtained in 93.8% of patients who received surgical treatment and in 94.5% of the radiotherapy group. Surgery resulted in 483 (483/2,175 = 22.2%) new cranial nerve permanent deficits, whereas in the EBRT group, no new deficits were recorded (p = 0.004). The common/internal carotid artery was resected in 271 (12.5%) patients because of injury or tumor encasement, with immediate reconstruction in 212 (9.7%) patients. Three percent (60) of patients developed a permanent stroke and 1.3% (26) died due to postoperative complications. The major complications rates and the mortality after completion of the treatment also were significantly higher in surgical series compared to EBRT series. This systematic analysis highlights evidence that EBRT offers a similar chance of tumor control with lower risk of morbidity as compared to surgery in patients with CBT. This questions the traditional notion that surgery should be the mainstay of treatment.

Is elective neck dissection indicated during salvage surgery for head and neck squamous cell carcinoma?

Among patients with head and neck squamous cell carcinoma with a negative neck who are initially treated with (chemo)radiotherapy, a number of cases will recur locally without obvious neck recurrence. There is little information available as to the most efficacious management of the neck in these cases. We have reviewed the literature to see what conclusions can be drawn from previous reports. We conducted a bibliography search on MEDLINE and EMBASE databases. Studies published in the English language and those on squamous cell carcinoma of the oral cavity, nasopharynx, oropharynx, larynx and hypopharynx were included. Data related to neck management were extracted from the articles. Twelve studies satisfied the inclusion criteria. Five studies reported only one treatment plan (either neck dissection or observation), while the others compared neck dissection to observation. The rate of occult metastases ranged from 3.4 to 12 %. The studies included a variable distribution of primary sites and stages of the recurrent primary tumors. The risk of occult neck node metastasis in a clinically rN0 patient correlated with tumor site and T stage. Observation of the neck can be suggested for patients with T1-2 glottic tumors, who recurred with less advanced tumors (rT1-2). For patients with more advanced laryngeal recurrences or recurrence at other high-risk sites, neck dissection could be considered for the rN0 patient, particularly if the neck was not included in the previous radiation fields.

Causes of death of patients with laryngeal cancer.

Despite remarkable advances in the care of patients with laryngeal cancer over the past several decades, including a growing awareness of therapeutic complications and attention to quality of life, little is known about the causes of mortality in this population. In addition to the laryngeal malignancy itself, acute and late or chronic treatment-associated causes, second primary cancers, intercurrent disease and psychosocial factors are all responsible for patient morbidity and mortality. We examine the current literature related to the causes of death in patients with laryngeal cancer, in the hope of guiding future interventions to improve the longevity and quality of life of individuals with this cancer.

Treatment of the neck in residual/recurrent disease after chemoradiotherapy for advanced primary laryngeal cancer.

Concomitant chemoradiotherapy (CRT) is extensively used as primary organ preservation treatment for selected advanced laryngeal squamous cell carcinomas (LSCC). The oncologic outcomes of such regimens are comparable to those of total laryngectomy followed by adjuvant radiotherapy. However, the management of loco-regional recurrences after CRT remains a challenge, with salvage total laryngectomy being the only curative option. Furthermore, the decision whether to perform an elective neck dissection (END) in patients with rN0 necks, and the extent of the neck dissection in patients with rN + necks is still, a matter of debate. For rN0 patients, meta-analyses have reported occult metastasis rates ranging from 0 to 31 %, but no survival advantage for END. In addition, meta-analyses also showed a higher incidence of complications in patients who received an END. Therefore, END is not routinely recommended in addition to salvage laryngectomy. Although some evidence suggests a potential role of END for supraglottic and locally advanced cases, the decision to perform END should weigh benefits against potential complications. In rN + patients, several studies suggested that selective neck dissection (SND) is oncologically safe for patients with specific conditions: when lymph node metastases are not fixed and are absent at level IV or V. Super-selective neck dissection (SSND) may be an option when nodes are confined to one level. In conclusion, current evidence suggests that in rN0 necks routine END is not necessary and that in rN + necks with limited nodal recurrences SND or a SSND could be sufficient.

The evolving role of selective neck dissection for head and neck squamous cell carcinoma.

Neck dissection is an important part of the surgical treatment of head and neck squamous cell carcinoma (HNSCC). The historical concept of neck dissection implied the removal of all lymph node-bearing tissue in the neck, which began in the late nineteenth century. However, more conservative variations of neck dissection have been performed and promoted as well. Anatomic, pathologic, clinical investigations, and prospective studies have demonstrated that the lymphatic dissemination of HNSCC occurs in predictable patterns. Supported by these studies, selective neck dissection (SND), which consists of the removal of select levels of lymph nodes in the neck that have the highest risk of harboring undetected metastases, has become widely accepted in the treatment of the clinically uninvolved neck. More recently, evidence supports using SND in a therapeutic setting in selected cases of HNSCC with limited metastatic disease. Additionally, even more targeted dissections referred to as super-selective neck dissection have been explored for selected patients undergoing elective node dissection for supraglottic cancer and as an adjuvant therapy for salvage of residual lymphadenopathy confined to a single neck level following chemoradiation. In the future, the trend to tailor treatment to individual patients and to limit toxicity and morbidity may further increase the use of SND. The indications have to be guided by further research, in relation with non-surgical treatment options while optimizing oncological effectiveness.

Follow-up strategies in head and neck cancer other than upper aerodigestive tract squamous cell carcinoma.

Post-therapy follow-up for patients with head and neck cancer other than upper aerodigestive tract squamous cell carcinoma should meet several objectives: to detect both local, regional or distant recurrences, to evaluate acute and long-term treatment-related side effects, to guide the rehabilitation process, and to provide psychosocial support when needed. To our knowledge, there are no published reports in the literature dedicated to the follow-up of patients with these tumours. A comprehensive literature search for post-treatment follow-up strategies spanning from 1980 to 2012 was performed on several databases. This review focuses on malignant salivary gland tumors, soft tissue sarcomas, cutaneous squamous cell carcinomas, and sinonasal adenocarcinomas. Given the varying biological behavior and treatment-related factors and based on the literature, different recommendations are made on the follow-up of patients with the above-mentioned tumors.

Superselective neck dissection: rationale, indications, and results.

It has been established that an appropriately indicated selective neck dissection can achieve the same oncologic results as more extensive dissections. An even more modified selective neck dissection, termed superselective neck dissection, involves the compartmental removal of the fibrofatty tissue contents within the defined boundaries of two or fewer contiguous neck levels. Evidence from retrospective studies suggests that superselective neck dissection (SSND) is oncologically sound for two indications: elective treatment of the clinically N0 neck and salvage treatment of persistent lymph node disease after chemoradiotherapy. While there is broader support for the former scenario, evidence that SSND may constitute optimal treatment in the latter is in conformity with the trend toward developing surgical techniques that provide better functional outcomes without compromising efficacy.

Post-therapeutic surveillance strategies in head and neck squamous cell carcinoma.

The management of head and neck squamous cell carcinomas does not end with the completion of ablative therapy. The oncologic objectives of post-treatment follow-up are to detect recurrences and second primary tumors; beyond that, follow-up should evaluate acute and chronic treatment-related side effects, guide the rehabilitation process, alleviate functional loss, manage pain, restore nutritional status and assess psychosocial factors. In this structured review, we address the questions of timing and the tools required to achieve a complete and coherent routine surveillance. Several guidelines and consensus statements recommend clinical examination as the cornerstone of follow-up which should be performed for at least 5 years, although there are no data in favor of any one particular follow-up program, and only low-level evidence suggests an improvement in oncologic outcomes by close follow-up. Baseline imaging (computed tomography and magnetic resonance imaging) should be obtained within 2-6 months after definitive therapy if used for treatment response evaluation. Metabolic response, if indicated, should be assessed preferably after 3 months in patients who undergo curative-intent therapy with (chemo)-radiotherapy. Chest computed tomography is more sensitive than plain radiography, if used in follow-up, but the benefit and cost-effectiveness of routine chest computed tomography has not been demonstrated. There are no current data supporting modifications specific to the surveillance plan of patients with human papillomavirus-associated disease.

Concomitant chemoradiotherapy versus acceleration of radiotherapy with or without concomitant chemotherapy in locally advanced head and neck carcinoma (GORTEC 99-02): an open-label phase 3 randomised trial.

BACKGROUND: Concomitant chemoradiotherapy and accelerated radiotherapy independently improve outcomes for patients with locally advanced head and neck squamous-cell carcinoma (HNSCC). We aimed to assess the efficacy and safety of a combination of these approaches. METHODS: In our open-label phase 3 randomised trial, we enrolled patients with locally advanced, stage III and IV (non-metastatic) HNSCC and an Eastern Cooperative Oncology Group performance status of 0-2. We randomly allocated patients centrally with a computer program (with centre, T stage, N stage, and localisation as minimisation factors) in a 1:1:1 ratio to receive conventional chemoradiotherapy (70 Gy in 7 weeks plus three cycles of 4 days' concomitant carboplatin-fluorouracil), accelerated radiotherapy-chemotherapy (70 Gy in 6 weeks plus two cycles of 5 days' concomitant carboplatin-fluorouracil), or very accelerated radiotherapy alone (64·8 Gy [1·8 Gy twice daily] in 3·5 weeks). The primary endpoint, progression-free survival (PFS), was assessed in all enrolled patients. This trial is completed. The trial is registered with ClinicalTrials.gov, number NCT00828386. FINDINGS: Between Feb 29, 2000, and May 9, 2007, we randomly allocated 279 patients to receive conventional chemoradiotherapy, 280 to accelerated radiotherapy-chemotherapy, and 281 to very accelerated radiotherapy. Median follow-up was 5·2 years (IQR 4·9-6·2); rates of chemotherapy and radiotherapy compliance were good in all groups. Accelerated radiotherapy-chemotherapy offered no PFS benefit compared with conventional chemoradiotherapy (HR 1·02, 95% CI 0·84-1·23; p=0·88) or very accelerated radiotherapy (0·83, 0·69-1·01; p=0·060); conventional chemoradiotherapy improved PFS compared with very accelerated radiotherapy (0·82, 0·67-0·99; p=0·041). 3-year PFS was 37·6% (95% CI 32·1-43·4) after conventional chemoradiotherapy, 34·1% (28·7-39·8) after accelerated radiotherapy-chemotherapy, and 32·2% (27·0-37·9) after very accelerated radiotherapy. More patients in the very accelerated radiotherapy group had RTOG grade 3-4 acute mucosal toxicity (226 [84%] of 268 patients) compared with accelerated radiotherapy-chemotherapy (205 [76%] of 271 patients) or conventional chemoradiotherapy (180 [69%] of 262; p=0·0001). 158 (60%) of 265 patients in the conventional chemoradiotherapy group, 176 (64%) of 276 patients in the accelerated radiotherapy-chemotherapy group, and 190 (70%) of 272 patients in the very accelerated radiotherapy group were intubated with feeding tubes during treatment (p=0·045). INTERPRETATION: Chemotherapy has a substantial treatment effect given concomitantly with radiotherapy and acceleration of radiotherapy cannot compensate for the absence of chemotherapy. We noted the most favourable outcomes for conventional chemoradiotherapy, suggesting that acceleration of radiotherapy is probably not beneficial in concomitant chemoradiotherapy schedules.

Pharyngeal Reconstruction Methods to Reduce the Risk of Pharyngocutaneous Fistula After Primary Total Laryngectomy: A Scoping Review.

INTRODUCTION: The most common early postoperative complication after total laryngectomy (TL) is pharyngocutaneous fistula (PCF). Rates of PCF are higher in patients who undergo salvage TL compared with primary TL. Published meta-analyses include heterogeneous studies making the conclusions difficult to interpret. The objectives of this scoping review were to explore the reconstructive techniques potentially available for primary TL and to clarify which could be the best technique for each clinical scenario. METHODS: A list of available reconstructive techniques for primary TL was built and the potential comparisons between techniques were identified. A PubMed literature search was performed from inception to August 2022. Only case-control, comparative cohort, or randomized controlled trial (RCT) studies were included. RESULTS: A meta-analysis of seven original studies showed a PCF risk difference (RD) of 14% (95% CI 8-20%) favoring stapler closure over manual suture. In a meta-analysis of 12 studies, we could not find statistically significant differences in PCF risk between primary vertical suture and T-shaped suture. Evidence for other pharyngeal closure alternatives is scarce. CONCLUSION: We could not identify differences in the rate of PCF between continuous and T-shape suture configuration. Stapler closure seems to be followed by a lower rate of PCF than manual suture in those patients that are good candidates for this technique.

Recurrent Differentiated Thyroid Cancer: The Current Treatment Options.

Differentiated thyroid carcinomas (DTC) have an excellent prognosis, but this is sometimes overshadowed by tumor recurrences following initial treatment (approximately 15% of cases during follow-up), due to unrecognized disease extent at initial diagnosis or a more aggressive tumor biology, which are the usual risk factors. The possible sites of recurrence are local, regional, or distant. Local and regional recurrences can usually be successfully managed with surgery and radioiodine therapy, as are some isolated distant recurrences, such as bone metastases. If these treatments are not possible, other therapeutic options such as external beam radiation therapy or systemic treatments should be considered. Major advances in systemic treatments have led to improved progression-free survival in patients previously considered for palliative treatments; among these treatments, the most promising results have been achieved with tyrosine kinase inhibitors (TKI). This review attempts to give a comprehensive overview of the current treatment options suited for recurrences and the new treatments that are available in cases where salvage surgery is not possible or in cases resistant to radioiodine.

A Meta-analysis of Surgical Outcomes of T4a and Infranotch T4b Oral Cancers.

OBJECTIVE: To determine the overall surgical outcomes of infranotch T4b oral cancers and compare them with T4a oral cancers. METHODS: PubMed, EMBASE and Cochrane databases from 2000 to 2022 were systematically searched. Clinical studies reporting at least one outcome following curative surgery and adjuvant therapy for comparison of patients with either infranotch T4b (IN-T4b) or T4a tumour. The heterogeneity of the included studies was determined using Tau-squared, Chi-squared, and the Higgins I2 test. The random effects model was used to determine the log odds ratio (logOR). RESULTS: The systematic review comprised 11,790 patients from 16 included studies. Seven studies were included in the meta-analysis (n = 11,381). For IN-T4b patients, the pooled 2 and 5 year overall survival (OS) were 59.3% and 53.2%, 2 and 5 year disease-free survival (DFS) 57.9% and 48.4%, 2 and 5 year disease-specific survival (DSS) 72% and 68%, and 2 and 5 year local control (LC), 47% and 56%, respectively. There was no statistically significant difference in 2 year OS [logOR = 0.28 (-0.47, 1.03), p = 0.46, confidence interval (CI) = 95%], 5 year OS [logOR = 0.7 (-0.4, 1.8), p = 0.54, CI = 95%], 2 year DFS [logOR = 0.22 (-0.35, 0.79), p = 0.45, CI = 95%], 5 year DFS [logOR = 0.17 (-0.42, 0.77), p = 0.57, CI = 95%], 2 year LC [logOR = 0.47 (-0.33, 1.26), p = 0.25, CI = 95%] and 5 year LC [logOR = 0.34 (-0.31, 0.99), p = 0.31, CI = 95%] between IN-T4b and T4a oral cancers. CONCLUSION: Results of this meta-analysis suggest that IN-T4b oral cancers have similar outcomes to T4a oral cancers, which supports down-staging IN-T4b cancers to T4a cancers.

Neck Surgery for Non-Well Differentiated Thyroid Malignancies: Variations in Strategy According to Histopathology.

Lymph node metastases in non-well differentiated thyroid cancer (non-WDTC) are common, both in the central compartment (levels VI and VII) and in the lateral neck (Levels II to V). Nodal metastases negatively affect prognosis and should be treated to maximize locoregional control while minimizing morbidity. In non-WDTC, the rate of nodal involvement is variable and depends on the histology of the tumor. For medullary thyroid carcinomas, poorly differentiated thyroid carcinomas, and anaplastic thyroid carcinomas, the high frequency of lymph node metastases makes central compartment dissection generally necessary. In mucoepidermoid carcinomas, malignant peripheral nerve sheath tumors, sarcomas, and malignant thyroid teratomas or thyroblastomas, central compartment dissection is less often necessary, as clinical lymphnode involvement is less common. We aim to summarize the medical literature and the opinions of several experts from different parts of the world on the current philosophy for managing the neck in less common types of thyroid cancer.

Management of the neck in the setting of definitive chemoradiation: is there a consensus? A GETTEC study.

BACKGROUND: The management of the neck remains controversial in the definitive chemoradiation setting of advanced N2-3 head and neck squamous cell carcinoma. Most published data favor omission of neck dissection (ND) after complete response for N2-3 or selective ND for residual disease METHODS: We studied the patterns of care in the French-Belgian Groupe d'Etude des Tumeurs de la Tête Et du Cou (GETTEC) through a questionnaire-based survey. RESULTS: Eighteen percent of institutions never performed up-front ND, 20% rarely, 40% sometimes, 14% often, and 8% systematically. Induction chemotherapy was indicated in 30% of the cases, and most ND were performed either between induction and radiation or after chemoradiation for residual disease. Response to chemoradiation was assessed by computed tomographic scan and positron emission tomography in 72% of cases. Selective ND was more common than radical ND. CONCLUSIONS: Omission of ND based on computed tomographic scan and positron emission tomography-based complete response to chemoradiation is the most common strategy for advanced nodal disease among centers. However, neck management strategies vary among institutions, and some institutions continue advocating systematic ND before irradiation. The new treatment options and the changing epidemiology, namely docetaxel-based induction chemotherapy and human papilloma virus-related head and neck squamous cell carcinoma having better response profiles and prognosis, are adding to the nonconsensual approach. The best therapeutic index in terms of neck management remains to be defined in this evolving context.
