A retrospective study of 56 patients with minimal access neck dissection. Br J Oral Maxillofac Surg 2024; 62:471-476. [PMID: 38685146 DOI: 10.1016/j.bjoms.2024.01.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 01/22/2024] [Accepted: 01/30/2024] [Indexed: 05/02/2024]
Abstract
The concept of neck dissection was introduced by Crile more than a century ago. Since then, multiple modifications have been adopted to ensure the preservation of vital structures. With the new era of minimal access surgery, the incorporation of laparoscopic, endoscopic, and robotic surgery is becoming the new normal. Over the years we have carried out neck dissections using minimal access incisions. Although there is no definitive answer about the average nodal yield required in selective or modified neck dissections, it has been reported that the average nodal yield of more than 18 is associated with better survival rate. In this publication we share the results of our three-year retrospective study of 56 patients who underwent minimal access neck dissection. We look at the nodal yield, assess operating duration, complications, outcome with a three-year follow up from a single unit. Our results demonstrate that minimal access neck dissection should be considered in head and neck lymphadenectomies.

Abstract
PURPOSE To develop a nomogram to predict the cancer-specific survival of patients with local-regionally advanced oropharyngeal squamous cell carcinoma after cervical lymph node dissection. METHODS The clinical variables of patients confirmed as having oropharyngeal squamous cell carcinoma between 2008 and 2015 were retrieved from the Surveillance, Epidemiology and End Results database. Univariate and multivariate analysis were performed, followed by the construction of nomograms for CSS. Nomogram' accuracy was evaluated through the concordance index, calibration curves and decision curve analysis. RESULTS A total of 1994 oropharyngeal squamous cell carcinoma patients who underwent surgery were included in this study. Sex, T-stage, American Joint Committee on Cancer-stage, positive lymph nodes, positive lymph node ratio, log odds of positive lymph nodes, and postoperative radiotherapy were selected to establish the nomogram for oropharyngeal squamous cell carcinoma. The concordance index of the nomogram was 0.747 (95% CI 0.714-0.780) in the training calibration cohort and 0.735 (95% CI 0.68-0.789) in the validationcohort and the time-dependent Area under the curve (> 0.7) indicated satisfactory discriminative ability of the nomogram. The calibration plot shows that there is a good consistency between the predictions of the nomogram and the actual observations in the training and validation cohorts. In addition, decision curve analysis showed that the nomogram was clinically useful and had a better ability to recognize patients at high risk than the American Joint Committee on Cancer tumor-node-metastasis staging. CONCLUSION The predictive model has the potential to provide valuable guidance to clinicians in the treatment of patients with locoregionally advanced OPSCC confined to the cervical lymph nodes.

Abstract
INTRODUCTION A yield of ≥18 nodes from neck dissection has been shown to be associated with improved locoregional recurrence rates and survival. We sought to determine factors associated with lymph node yields below this threshold. MATERIALS AND METHODS A retrospective review of patients who underwent neck dissection as part of definitive surgical treatment for mucosal head and neck squamous cell carcinoma (SCC) between January 2015 and December 2018 at an academic tertiary referral center was performed. Patients with a history of prior radiation or neck dissection were excluded. RESULTS There were 412 neck dissections performed in 323 patients. Specimens containing <18 nodes decreased from 16.2% in 2015-2016 to 7.4% of neck dissections in 2017-2018. The proportion of neck dissections removing <3 levels decreased from 9.1% of neck dissections in 2015-2016 to 4.0% in 2017-2018. Multivariable regression analysis demonstrated that dissection of ≥3 levels (OR = 0.2 [0.1-0.4]) and neck dissection in 2017-2018 compared to 2015-2016 (OR = 0.4 [0.2-0.8]) were significantly associated with a lower odds of <18 nodes. Stage, site, race, sex, human papillomavirus status, positive nodes, surgeon volume, and pathologist volume were not associated with neck dissection specimens with <18 nodes, after controlling for all other variables. CONCLUSIONS Increased recognition of the importance of node count as a quality indicator, and the extent of neck dissection is associated with increased nodal yield from neck dissection. These data suggest that node count can be used as a quality measure of neck dissection for mucosal SCC. LEVEL OF EVIDENCE 4 Laryngoscope, 133:2160-2165, 2023.

Abstract
OBJECTIVES To investigate thresholds for lymph node yield (LNY), lymph node density (LND), and pN in patients with oral squamous cell carcinoma in relation to previous findings in the literature. STUDY DESIGN Retrospective register-based study. SETTING Copenhagen Oral Cavity Squamous Cell Carcinoma database. METHODS Appropriate thresholds for LNY, LND, and pN were determined by areas under the curve and subsequently subjected to multivariate analysis. Five-year overall survival and 3-year recurrence-free survival were determined by Kaplan-Meier survival curves. RESULTS In total, 413 patients diagnosed with oral squamous cell carcinoma were included. In the pN0 cohort, no superior/prognostic LNY cutoff values were detected. In the pN+ cohort, areas under the curve determined thresholds of LNY, LND, and pN to be 21 nodes, 5%, and 3 metastases, respectively. The 5-year overall survival was 52% for patients with LNY ≥21 vs 38% for patients with LNY <21 (hazard ratio [HR], 1.49; 95% CI, 1.05-2.11; P < .05), 60% for patients with LND ≤5% vs 38% for patients with LND >6% (HR, 1.63; 95% CI, 1.03-2.57; P < .05), and 43% for patients with pN <3 vs 26% for patients with pN ≥3 (HR, 1.40; 95% CI, 1.04-2.15; P < .05). CONCLUSIONS Increased nodal yield, decreased LND, and decreasing number of pN were associated with significantly improved survival outcomes. LNY might serve as a prognosticator of survival as well as a surgical quality indicator. LND may have implications as a tool in cancer staging and treatment planning.

Abstract
BACKGROUND The study investigates the prognostic significance of lymph node ratio (LNR) on patients with head and neck squamous cell carcinoma (HNSCC) with coexistence of multiple adverse pathological features. METHODS In total, 100 patients with coexistence of perineural invasion, lymphovascular invasion, and extranodal extension of first primary HNSCC treated with radical surgery followed by adjuvant chemoradiotherapy were enrolled. RESULTS The optimal LNR cut-off value for predicting overall survival (OS) and cancer specific survival (CSS) was 7%. In Cox model, we observed that LNR ≥7% was a statistically significant unfavorable predictor of OS (HR: 2.689; 95% CI: 1.228-5.889; p = 0.013) and CSS (HR: 3.162; 95% CI: 1.234-8.102; p = 0.016). CONCLUSION For HNSCC patients with coexistence of multiple adverse pathological features, LNR is an independent survival predictor. Novel intensified treatments are needed for the subgroup of patients with a high LNR.

Traditional risk factors and nodal yield-still relevant with high-quality risk-adapted adjuvant treatment for locally advanced head and neck cancer? Strahlenther Onkol 2023; 199:284-292. [PMID: 36350358 DOI: 10.1007/s00066-022-02017-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/28/2022] [Indexed: 11/11/2022]
Abstract
OBJECTIVE Patients with locally advanced head and neck cancer (LAHNC) often undergo multimodal therapy including radical resection of the primary tumor and neck dissection (ND) followed by risk-adapted adjuvant radio(chemo)therapy (R(C)T). Quality parameters influencing local control and survival of these patients have been postulated: resection status (R status), extranodal extension (ENE), interval to adjuvant treatment ≤6 weeks, R(C)T given when indicated, and nodal yield (NY) ≥18 lymph nodes per neck. For other solid tumors the trend is towards less extensive lymph node surgery to avoid toxicity such as lymphedema, damage to peripheral nerves, dysesthesia, or paresthesia. The present study aims to investigate whether the number of nodes removed during neck dissection for LAHNC is still predictive for outcome when patients receive risk-adapted adjuvant treatment according to current guidelines. METHODS Between 2008 and 2015, 468 patients with LAHNC undergoing R(C)T with curative intent were prospectively registered in a database (UICC III/IV). Among them, 359 patients received adjuvant treatment and 295 underwent neck dissection. There were 119 (40%) patients with an oropharyngeal primary, 49 (17%) with cancer of the larynx/hypopharynx, 88 (30%) of the oral cavity, and 39 (13%) of the nasal/paranasal sinuses and cancer of unknown primary (CUP). Median follow-up was 45.6 months. Histopathology revealed an R1 status in 65 (22%) cases and ENE in 93 (31%) cases. 150 (51%) patients received RCT; the median time to adjuvant treatment from the day of tumor resection was 44 days (35-54) and overall treatment time (OTT; time from surgery to the last day of R(C)T) was 90 days (82-101). Factors influencing disease-free survival (DFS) were adjusted and analyzed using CART analysis (removed nodes, number of positive nodes, body mass index (BMI), ENE, T and N classification, R status, and primary site). Local control (LC), distant metastases-free survival (DMFS), and overall survival (OS) were analyzed using Kaplan-Meier statistics and multivariate analysis (MVA) for factors predictive for DFS and OS. RESULTS CART analysis (Classification and Regression Trees) showed that T classification (T3/4) is the most important predictor for DFS, followed by age (> 61 years) and BMI (< 17.4). Primary site (OPC vs. other) and number of removed nodes (< 17) were shown to be less important for DFS, while ECE, N classification, and R status seem to be of little relevance. MVA revealed number of positive nodes, non-OPC, and T3/4 to be negative predictive factors for DFS. For OS, the number of positive nodes and non-OPC primary were predictive. Five-year rates were 86.1% for LC, 87.9% DMFS, 76.5% DFS, and 67.2% for OS. CONCLUSION In this patient cohort, the number of removed nodes is not relevant for DFS and OS, while the number of positive nodes and T classification have a negative impact on these endpoints. The high-risk factors positive resection margin and ECE seem to lose their negative impact on DFS and OS. High-quality care in head and oncology is only possible within a close multidisciplinary team and network.

Abstract
OBJECTIVES To compare overall survival outcomes associated with transoral laser microsurgery (TLM) with neck dissection versus definitive radiotherapy in the management of T2N0 supraglottic squamous cell carcinoma. METHODS Data were extracted from the National Cancer Database concerning patients with cT2N0M0 supraglottic cancer treated with either TLM and neck dissection with minimum lymph node yield of 10 or definitive radiotherapy. Predictors of overall survival were assessed via Cox proportional hazards regression. RESULTS Seventy-six cT2N0 supraglottic squamous cell carcinoma patients who underwent TLM with neck dissection (+/- adjuvant therapy) versus 991 patients who underwent radiotherapy. TLM was associated with an overall survival benefit (OR = 0.574; 95% CI 0.383-0.860) compared with radiotherapy. There was no difference in survival between TLM patients receiving adjuvant treatment and those receiving definitive radiotherapy. CONCLUSIONS An up-front, TLM-based surgical approach to cT2N0 supraglottic cancer may offer an overall survival benefit compared with definitive radiotherapy, and should receive more frequent consideration as a primary approach to this disease process.

Abstract
In this study, we aimed to investigate the prognostic value of the number of pathologically positive nodes (pN+) in p16-negative oropharyngeal (OPSCC) and hypopharyngeal (HPSCC) squamous cell carcinoma cases with pN3b status after surgery. We reviewed the clinical and pathological features of 120 newly diagnosed p16-negative OPSCC and HPSCC patients with pN3b status after radical surgery. The primary endpoints were the 5-year overall survival (OS), cancer-specific survival (CSS), and their prognostic factors. We used the Cox proportional hazards model for survival analysis. We generated predictive nomograms that incorporated the clinicopathological factors of OS and CSS. The 5-year OS and CSS rates were 44.1% and 59.1%, respectively. The optimal number of pN+ to predict the 5-year OS and CSS was pN+ = 3. In the Cox model, we observed that pN+ ≥ 3 was a significantly negative predictor of OS (HR: 1.9, 95% CI: 1.1–3.2, p = 0.021) and CSS (HR: 2.3; 95% CI: 1.2–4.6; p = 0.015). After adding the pN+ variable, the c-index of the predictive nomogram incorporating assorted clinicopathological factors increased from 0.66 to 0.689 for OS and from 0.713 to 0.75 for CSS. The results highlight the prognostic value of the pN+ number in p16-negative OPSCC and HPSCC patients with pN3b status.

Phys Imaging Radiat Oncol 2022; 20:76-81. [PMID: 35169639 PMCID: PMC8829887 DOI: 10.1016/j.phro.2021.10.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Revised: 10/29/2021] [Accepted: 10/29/2021] [Indexed: 11/24/2022] Open
Abstract
Individual elective lymph nodes can be identified using multiple Dixon T2-weighted turbo spin echo with fat suppression. Magnetic Resonance guided individual lymph node irradiation results in lower dose to the organs at risk. Especially the submandibular glands, carotid arteries and thyroid can be spared. The magnetic field on the magnetic resonance imaging - linear accelerator did not lead to increased skin dose depositions.
Background and purpose Conventional elective neck irradiation (ENI) in head and neck cancer consists of radiotherapy (RT) to the regional lymph node (LN) levels contoured on computed tomography. Hybrid Magnetic Resonance (MR) - RT modalities, such as combined magnetic resonance imaging - linear accelerators (MRLs), might enable new ENI strategies in which individual non-suspect lymph nodes (i-LNs) are targeted. In this treatment planning study, new MR-based strategies targeting i-LNs (i-ENI) were compared to conventional treatment. Materials and methods All i-LNs were delineated on MR images of ten retrospectively selected patients with T2-4aN0M0 laryngeal cancer. Three strategies were considered. Strategy A: Conventional ENI delivered with a conventional linear accelerator (35x 1.55 Gy). Strategy B: MRL-based i-ENI (35x 1.55 Gy) to the individual lymph nodes including a background dose to the conventional elective neck volumes (35x 1.03 Gy). Strategy C: Same as Strategy B, but without background dose. In all plans the dose prescription to the primary tumor was 35x 2 Gy. Mean dose (Dmean) reductions in the organs at risk (OAR) were compared using the Wilcoxon signed rank test. Results Compared to conventional ENI (strategy A), significant Dmean reductions of 6.0 Gy and 8.0 Gy were observed in the submandibular glands, of 9.4 Gy and 13 Gy in the carotid arteries and of 9.9 Gy and 19.4 Gy in the thyroid for strategy B and C, respectively. Large inter-patient variations of Dmean reductions were observed in all OARs. Conclusion MRL-based i-ENI is a new promising concept that could reduce the mean dose to OARs in the neck significantly for patients with laryngeal cancer.

Abstract
PURPOSE OF REVIEW The purpose of this review is to highlight the most important changes in the eighth TNM classification system for oral squamous cell carcinomas compared with the seventh edition with focus on lymph node staging (pN). Nodal involvement is crucial when addressing prediction of survival, and staging must mirror the disease extension. pN classification will be evaluated with respect to lymph node yield (LNY), lymph node density (LND), and a recently proposed classification: pN-N+ reflecting positive regional lymph nodes (metastatic burden) and extra nodal extension. RECENT FINDINGS TNM8 was introduced in 2018, and the most noteworthy changes were depth of invasion (DOI) and extranodal extension (ENE). Recent studies indicate, that TNM8-related pN is not superior to TNM7 with respect to predicting survival. LNY and LND are biased with ecological interference fallacy, and currently not recommended in future iterations of TNM. In contrast, the pN-N+ classification has demonstrated improved survival prediction compared with TNM8. SUMMARY The recent findings support the inclusion of pN-N+, that is, metastatic burden and extranodal extension in future iterations of TNM.

Prognostic value of the nodal yield in elective neck dissections in patients with head and neck carcinomas. Eur Arch Otorhinolaryngol 2021; 279:883-889. [PMID: 33938992 DOI: 10.1007/s00405-021-06819-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 04/09/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE The objective of this study is to assess the prognostic capacity of the nodal yield in elective neck dissections performed in patients with head and neck squamous cell carcinomas (HNSCC) without clinical or radiological evidence of regional involvement (cN0) at the time of diagnosis. METHODS Retrospective study including 647 patients with HNSCC treated with an elective neck dissection. RESULTS Patients with < 15 dissected nodes (n = 172, 26.6%) had a 5-year disease-specific survival of 64.9% (95% CI: 57.3-72.5%), while for patients with ≥ 15 dissected nodes (n = 475, 73.4%), it was of 81.9% (95% CI: 78.4-85.4%) (P = 0.0001). The nodal yield category had prognostic capacity on the disease-specific survival in patients with tumors located in the oral cavity (P = 0.001), the oropharynx (P = 0.023) and the hypopharynx (P = 0.034), while for patients with tumors located in the larynx, no significant differences appeared (P = 0.779). Differences in regional recurrence-free survival were also observed based on the nodal yield category in patients with extra-laryngeal tumors (5-year regional recurrence-free survival of 81.0% in patients with < 15 dissected nodes vs 89.0% in patients with ≥ 15 dissected nodes; P = 0.046). CONCLUSION The nodal yield in elective neck dissections in patients without evidence of lymph node disease (cN0) had prognostic capacity depending on the location of the primary tumor. For tumors located in the larynx, the number of dissected nodes did not significantly influence the prognosis. For tumors located in the oral cavity, oropharynx or hypopharynx, patients with < 15 dissected nodes had a disease-specific mortality 2.9 times higher than patients with ≥ 15 dissected nodes.

Abstract
BACKGROUND Lymph node yield is an important prognostic factor in head and neck squamous cell carcinoma. Variability in neck dissection sampling techniques has not been studied as a determinant of lymph node yield. METHODS This retrospective study used lymph node yield and average nodes per level to compare level-by-level and en bloc neck dissection sampling methods, in primary head and neck squamous cell carcinoma cases operated between March 2017 and February 2020. RESULTS From 123 patients, 182 neck dissections were analysed, of which 133 were selective and the rest were comprehensive: 55 had level-by-level sampling and 127 had undergone en bloc dissection. The level-by-level method yielded more nodes in all neck dissections combined (20 vs 17; p = 0.097), but the difference was significant only for the subcohort of selective neck dissection (18.5 vs 15; p = 0.011). However, the gain in average nodes per level achieved by level-by-level sampling was significant in both groups (4.2 vs 3.33 and 4.4 vs 3, respectively; both p < 0.001). CONCLUSION Sampling of cervical lymph nodes level-by-level yields more nodes than the en bloc technique. Further studies could verify whether neck dissection sampling technique has any impact on survival rates.

Abstract
Objectives: To analyze the significance of the number of positive lymph nodes in oral squamous cell carcinoma (SCC) stratified by p16. Methods: A total of 674 patients were retrospectively enrolled and divided into 4 groups based on their number of positive lymph nodes (0 vs. 1–2 vs. 3–4 vs. ≥5). The Kaplan-Meier method was used to calculate the disease-free survival (DFS) and disease-specific survival (DSS) rates. Cox model was used to evaluate the independent risk factor. Results: p16 showed positivity in 85 patients with a rate of 12.6%. In patients with p16 negativity, the 5-year DFS rates were 52%, 39%, and 21% in patients with 0, 1–2, and 3–4 positive lymph nodes, respectively, in patients with ≥5 positive lymph nodes, all patients developed recurrence within 2 years after operation, the difference was significant; the 5-year DSS rates were 60, 38, and 18% in patients with 0, 1–2, and 3–4 positive lymph nodes, respectively, in patients with ≥5 positive lymph nodes, all patients died within 4-years after operation. The difference was significant. In p16 positivity patients, the 3-year DFS rates were 41% and 17% in patients with 0–2 and ≥3 positive lymph nodes, respectively, the difference was significant; the 3-year DSS rates were 84 and 46% in patients with 0–2 and ≥3 positive lymph nodes, the difference was significant. Conclusions: The number of positive lymph nodes is significantly associated with the survival in oral SCC, its survival effect is not affected by p16 status.

Comparing Technical Feasibility of Non-robotic Retroauricular Versus Transcervical Approach Neck Dissection in Oral Cancers-a Preliminary Single Institute Experience. Indian J Surg Oncol 2020; 11:589-596. [PMID: 33299277 DOI: 10.1007/s13193-020-01252-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Accepted: 10/15/2020] [Indexed: 01/29/2023] Open
Abstract
Recent advances in minimal access/invasive surgeries in head and neck (robotic/endoscopic assisted) allow neck dissection without a visible scar through a retroauricular approach unlike conventional approach giving visible scar and its sequelae. We retrospectively reviewed prospectively collected data of 80 neck dissections in 72 patients from April 2017 to June 2018 for all newly diagnosed squamous cell carcinoma of oral cavity. We compared between the operative and postoperative outcomes in open- and endoscopic-assisted retroauricular approach (RA) in these patients undergoing neck dissections. Thirty-two out of seventy-two patients underwent retroauricular (RA) approach neck dissection while 40/72 patients underwent conventional open approach neck dissection. RA group had more early staged oral cancers 20/32 (62.5%) as compared to 9/40 (22.5%) in the open approach (p = 0.025). Average nodal yield and nodal yield according to levels were not statistically different in both groups. Nodal failure in both groups was also not statistically significant (p = 0.82). Postoperative complications like marginal weakness, hematoma, microvascular-related problems, and wound problems were not significantly related to the type of approach. We recommend in select group of early oral cancers the retroauricular-assisted neck dissection as minimally invasive, cost-effective, and oncologically safe approach for a scar-free neck surgery.

Abstract
BACKGROUND Process-related measures have been proposed as quality metrics in head and neck cancer care. A recent single-institution study identified four key metrics associated with increased survival. This study sought to validate the association of these quality metrics with survival in a multi-institutional cohort. METHODS Multicenter retrospective study of patients with oral cavity squamous cell (1/2005-1/2015). Baseline patient and disease characteristics and compliance with quality metrics was evaluated. Association between compliance with quality metrics with overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) was evaluated using Cox proportional hazards models. RESULTS Failure to comply with two or more of the quality metrics was associated with worse OS, DFS, and DSS. Adherence to all or all but one of the quality metrics was found to be associated with improved survival. CONCLUSIONS Process-related quality metrics are associated with increased survival in patients with oral cavity squamous cell carcinoma in a multi-institutional cohort.

Abstract
PURPOSE Controversies exist in regard to surgical neck management in total laryngectomies (TL). International guidelines do not sufficiently discriminate neck sides and sublevels, or minimal neck-dissection nodal yield (NY). METHODS Thirty-seven consecutive primary TL cases from 2009 to 2019 were retrospectively analyzed in terms of local tumor growth using a previously established imaging scheme, metastatic neck involvement, and NY impact on survival. RESULTS There was no case of level IIB involvement on any side. For type A and B tumor midline involvement, no positive contralateral lymph nodes were found. Craniocaudal tumor extension correlated with contralateral neck involvement (OR: 1.098, p = 0.0493) and showed increased involvement when extending 33 mm (p = 0.0134). Using a bilateral NY of ≥ 24 for 5-year overall survival (OS) and ≥ 26 for 5-year disease-free survival (DFS) gave significantly increased rate advantages of 64 and 56%, respectively (both p < 0.0001). CONCLUSIONS This work sheds light on regional metastatic distribution pattern and its influence on TL cases. An NY of n ≥ 26 can be considered a desirable benchmark for bilateral selective neck dissections as it leads to improved OS and DFS. Therefore, an omission of distinct neck levels cannot be promoted at this time.

Abstract
BACKGROUND Lymph node yield (LNY) is a proposed quality indicator in neck dissection for oral cavity squamous cell carcinoma (OCSCC). METHODS Retrospective series including 190 patients with OCSCC undergoing neck dissection between 2016 and 2018. A change in pathologic grossing protocol was initiated during the study period to assess residual adipose tissue. A generalized linear model was used to assess the impact of multiple variables on LNY. RESULTS Mean LNY was 28.59 (SD = 17.65). The protocol identified a mean of 10.32 lymph nodes per case. Multivariable analysis identified associations between LNY and use of the pathology protocol (P = .02), number of dissected lymph node levels (P < .001), presence of pathologic lymph nodes (P = .002), body mass index (P = .02), prior neck surgery (P = .001), and prior neck radiation (P = .001). CONCLUSIONS Assessment of residual adipose tissue within neck dissection specimens improves accuracy of LNY. LNY in neck dissection is influenced by multiple factors including methods of pathologic assessment.

Abstract
BACKGROUND The prognostic value of lymph node yield (LNY) and lymph node ratio (LNR), or the ratio of number of metastatic LNs to total number dissected, has not been well established in p16-associated oropharyngeal squamous cell carcinoma (OPSCC). METHODS This retrospective cohort study evaluated locoregional disease-free survival (LRDFS) in 82 patients with p16+ OPSCC who underwent neck dissection at a single institution from 2009 to 2017. LNR and LNY cutoffs were estimated using time-dependent receiver operator characteristic (ROC) curves. Prognostic significance of these cutoffs was compared with Eighth Edition AJCC Nodal Staging. RESULTS An increased LNR ≥ 0.129 was associated with worse 2-year LRDFS (66.9% vs 96.8%, P = .005). LNY was not significantly associated with LRDFS (P = .304). An LNR-based risk model was a better prognosticator than Eighth Edition AJCC Nodal Staging (Harrell's C, 0.9065 vs 0.7668). CONCLUSIONS LNR has good prognostic utility in predicting LRDFS in p16+ OPSCC, but further evaluation of this measure is warranted.

Abstract
To investigate the characteristics of recurrent branchial cleft anomalies (BCAs) and to evaluate the surgical technique and outcomes of patients undergoing reoperation.From January 2005 to August 2018, the clinical data of 216 patients with recurrent second, third, and fourth BCAs were retrospectively analyzed. According to the embryological and anatomical features of the cleft palate and recurrence site, selective neck dissection techniques were used for surgical treatment.Among all 216 patients, 203 healed by primary healing. Twelve patients with local infections and 1 patient with a pharyngeal fistula healed after dressing changes. Eleven patients experienced transient hoarseness and recovered after a few months. Three patients developed permanent hoarseness, and 5 patients developed coughing after eating and drinking. Three patients underwent internal jugular vein ligation. Only 4 recurrences occurred during a follow-up period of more than 1 year. The total cure rate was 98.15%.Selective neck dissection is an effective and safe surgical treatment for recurrent second, third, and fourth branchial cleft anomalies.

Abstract
Neck dissection (ND) is an essential component of treatment in head and neck squamous cell carcinoma (HNSCC). The extent of ND depends on primary tumor location and T and N stage. Trials have demonstrated improved survival for cN+ status with therapeutic ND as well as for cN0 status with selective ND if the primary has a high incidence of occult metastasis. The accuracy of the procedure is of prognostic relevance. In the prognostic model of the TNM classification, the parameter "N" does not only reflect the number of affected lymph nodes, but also their size and extranodal tumor extension. Due to its better prognosis, a positive human papillomavirus (HPV) status is also incorporated in the present TNM classification. In order to minimize morbidity after ND, one seeks to limit its extent without reducing survival time. To this aim, sentinel node biopsy or surveillance with positron-emission computed tomography (PET-CT) in cN0 necks or after primary radio(chemo)therapy are being investigated.

Abstract
OBJECTIVES The National Comprehensive Cancer Network (NCCN) guidelines state that surgical patients with advanced-stage head and neck cancer (HNC) and risk factors other than extranodal extension (ENE) or positive margins should consider post-operative chemoradiation (POCRT). The goal of our study was to determine if POCRT is associated with overall survival (OS) compared with post-operative radiation therapy (PORT) and whether this varies with patient age. MATERIAL AND METHODS We conducted a retrospective study of 5319 adult patients with stage III-IV HNC who received primary surgical treatment with POCRT or PORT in the National Cancer Database (2010-2013). Patients with distant metastases, ENE, and positive margins were excluded. Intermediate risk features included pT3-T4, pN2-N3 disease, and lymphovascular invasion. Our main outcome was overall survival (OS). Statistical analysis included chi-squared tests and Cox proportional hazards regressions. RESULTS On multivariable analysis for non-oropharyngeal cancer patients <70 years, POCRT was associated with improved OS for T1-4N2-3 disease (hazard ratio [HR], 0.73, 95% confidence interval [CI]; 0.58-0.93) but was not associated with OS for T3-4N0-1 disease (HR, 0.92; 95% CI, 0.71-1.19). For patients ≥70 years, POCRT was not associated with improved OS for patients with T1-4N2-3 disease (HR, 1.21; 95% CI, 0.79-1.86) or T3-4N0-1 disease (HR, 1.08; 95% CI, 0.71-1.65). For oropharyngeal cancer patients with HPV-positive disease, POCRT was associated with decreased OS (HR, 9.52; 95% CI, 2.38-38.08). CONCLUSION Chemoradiation may offer a survival benefit for non-oropharyngeal intermediate-risk advanced-stage HNC patients <70 years of age with T1-4N2-3 disease, but may not benefit those ≥70 years of age or those with T3-4N0-1 disease.
