Abstract
PURPOSE Substantial changes have been made in the neck management of patients with head and neck squamous cell carcinomas (HNSCC) in the past century. These have been fostered by changes in cancer epidemiology and technological progress in imaging, surgery, or radiotherapy, as well as disruptive concepts in oncology. We aimed to review changes in nodal management, with a focus on HNSCC patients with nodal involvement (cN+) undergoing (chemo)radiotherapy. METHODS A narrative review was conducted to review current advances and address knowledge gaps in the multidisciplinary management of the cN+ neck in the context of (chemo)radiotherapy. RESULTS Metastatic neck nodes are associated with poorer prognosis and poorer response to radiotherapy, and have therefore been systematically treated by surgery. Radical neck dissection (ND) has gradually evolved toward more personalized and less morbid approaches, i.e., from functional to selective ND. Omission of ND has been made feasible by use of positron-emission tomography/computed tomography to monitor the radiation response in cN+ patients. Human papillomavirus-driven oropharyngeal cancers and their cystic nodes have shown dramatically better prognosis than tobacco-related cancers, justifying a specific prognostic classification (AJCC) creation. Finally, considering the role of lymph nodes in anti-tumor immunity, de-escalation of ND and prophylactic nodal irradiation in combination are intense areas of investigation. However, the management of bulky cN3 disease remains an issue, as aggressive multidisciplinary strategies or innovative combined treatments have not yet significantly improved their prognosis. CONCLUSION Personalized neck management is an increasingly important aspect of the overall therapeutic strategies in cN+ HNSCC.

Abstract
Detection of extranodal extension on histopathology in surgically treated head and neck squamous cell carcinoma indicates poor prognosis. However, there is no consensus on the diagnostic criteria, interpretation, and reporting of histology detected extranodal extension, which has contributed to conflicting evidence in the literature, and likely clinical inconsistency. The Head and Neck Cancer International Group conducted a three-round modified Delphi process with a group of 19 international pathology experts representing 15 national clinical research groups to generate consensus recommendations for histology detected extranodal extension diagnostic criteria. The expert panel strongly agreed on terminology and diagnostic features for histology detected extranodal extension and soft tissue metastasis. Moreover, the panel reached consensus on reporting of histology detected extranodal extension and on nodal sampling. These consensus recommendations, endorsed by 19 organisations representing 34 countries, are a crucial development towards standardised diagnosis and reporting of histology detected extranodal extension, and more accurate data collection and analysis.

Oral Surg Oral Med Oral Pathol Oral Radiol 2024; 137:632-639. [PMID: 38679502 DOI: 10.1016/j.oooo.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 03/06/2024] [Accepted: 03/17/2024] [Indexed: 05/01/2024]
Abstract
OBJECTIVE Extranodal extension (ENE) is an important prognostic factor in oral squamous cell carcinoma (OSCC). This study aimed to evaluate the clinical significance of stratifying minor or major ENE in OSCC. STUDY DESIGN This retrospective cohort study included 75 patients who had undergone neck dissection for OSCC and were classified as pN+. ENE was measured using hematoxylin-eosin-stained specimens and stratified into major (ENEma, >2 mm) and minor (ENEmi, ≤2 mm) by distance. Their association with survival, locoregional relapse, and distant metastases were assessed. RESULTS Of 49 patients with pathological ENE, 23 had ENEmi, and 26 had ENEma. The 5-year overall survival (OS) was 38%, 66%, and 76% in the ENEma, ENEmi, and no ENE groups, respectively. Compared with no ENE, ENEma was associated with significantly decreased 5-year cumulative OS and disease-specific survival. ENEma was a risk factor for decreased OS (HR: 2.54, 95% CI: 1.04-6.18, P = .040) in the multivariable Cox regression analysis, and was associated with distant metastasis. CONCLUSION In patients with OSCC, ENEma is associated with a significantly poorer prognosis; therefore stratifying ENE is clinically relevant. ENEma may increase the risk of distant metastasis; therefore, new treatment modalities that contribute to distant metastasis control are required.

Abstract
We present a cohort review of TORS resection for HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) and its associated oncological outcomes spanning a 10-year period. A retrospective case series review was performed of patients undergoing primary surgical treatment for HPV-associated OPSCC through the St. Vincent's Head and Neck Cancer service from 2011 to 2022. The primary outcomes were to investigate complete resection of the primary tumour, rates of recurrence, and survival analysis. Secondary outcomes included complications, rates of adjuvant therapy, sites of recurrence and rates of percutaneous endoscopic gastrostomy (PEG). 184 patients underwent TORS-based therapy with neck dissection, and guideline-directed adjuvant therapy for HPV-associated OPSCC. Our median follow-up was 46 months. The positive margin rate on final histopathology analysis was 10.9%. Adjuvant therapy was indicated in 85 patients (46%). The local recurrence rate was 10.9% with the majority (80%) of patients recurring in the first 3 years since treatment. The disease-specific survival at 3 years was 98.6% and at 5 years was 94.4%. The 3-year and 5-year OS for the cohort was 96.7% and 92.5%, respectively. The presence of extranodal extension and positive margins were associated with increased risk of recurrence, whereas adjuvant therapy was found to be a protective factor for both overall recurrence and survival. Major complications occurred in 12 patients (6.5%), resulting in one death. This study has demonstrated that primary surgical therapy for HPV-associated OPSCC is a safe and effective treatment modality with low local recurrence and complication rates, and overall survival benefits.

Abstract
Objective Although large retrospective database studies have associated extranodal extension (ENE) with worse survival in several head and neck cancers, the prognostic significance of ENE in laryngeal squamous cell carcinoma (LSCC) remains unclear. Our study examines ENE and overall survival (OS) in LSCC. Methods The 2006-2017 National Cancer Database was queried for patients with LSCC undergoing surgical resection and neck dissection, with or without adjuvant therapy. Kaplan-Meier and multivariable Cox regression survival analyses were implemented to identify the independent impacts of pathologic nodal (pN) classification and ENE on OS. Results Of 4208 patients satisfying inclusion criteria, 2343 (55.7%) were pN0/ENE-negative, 1059 (25.2%) were pN1-2/ENE-negative, and 806 (19.2%) were pN1-2/ENE-positive. The 5-year OS of pN0/ENE-negative, pN1-2/ENE-negative, and pN1-2/ENE-positive patients was 62.8%, 56.7%, and 32.9%, respectively (p < .001). Among pN1-2/ENE-positive patients undergoing no adjuvant therapy, adjuvant radiotherapy alone, and adjuvant chemoradiotherapy, 5-year OS was 24.1%, 30.7%, and 36.7%, respectively (p < .001). After adjusting for patient demographics, clinicopathologic features, and adjuvant therapy, ENE-positivity was associated with worse OS than ENE-negativity (adjusted hazard ratio [aHR] 1.76, 95% confidence interval [CI] 1.53-2.02, p < .001). pN1/ENE-positivity (aHR 1.82, 95% CI 1.31-2.54) and pN2/ENE-positivity (aHR 1.89, 95% CI 1.49-2.40) were associated with worse OS than pN1/ENE-negativity (p < .001). Microscopic (aHR 1.83, 95% CI 1.54-2.18) and macroscopic ENE-positivity (aHR 1.75, 95% 1.35-2.26) were associated with worse OS than ENE-negativity (p < .001). Conclusion ENE-positivity has prognostic significance in LSCC and is associated with worse OS than ENE-negativity. pN classification did not have prognostic significance independent of ENE. ENE should be carefully considered when determining the prognosis of LSCC and selecting adjuvant therapy. Level of Evidence 4.

Abstract
PURPOSE OF REVIEW In 2017, the American Joint Committee on Cancer (AJCC) introduced the inclusion of extracapsular nodal extension (ENE) into the N staging of nonviral head and neck squamous cell carcinoma (HNSCC), while retaining the traditional N classification based on the number and sizes of metastatic nodes. The extent of ENE was further defined as microscopic ENE (ENEmi) and major ENE (ENEma) based on extent of disease beyond the nodal capsule (≤ or > 2 mm). This article reviews the evidence and progress made since these changes were introduced. RECENT FINDINGS The 'gold standard' for evaluation ENE is histopathologic examination, the current preferred primary treatment of patients with HNSCC is by radiation-based therapy ± chemotherapy or biotherapy. The current pretreatment staging is by imaging, which needs improved reliability of radiologic rENE assessment with reporting needs to consider both sensitivity and specificity (currently computed tomography images have high-specificity but low-sensitivity). Adjuvant chemotherapy is indicated for patients with ENEma to enhance disease control, whereas for patients with ENEmi, there is a need to assess the benefit of adjuvant chemotherapy. Evidence that the presence of pENE in HPV-positive oropharyngeal carcinoma is an independent prognostic factor and should be considered for inclusion in future AJCC editions has recently emerged. SUMMARY There remains a paucity of data on the reliability of imaging in the staging of rENE, more so the for the accurate assessment of ENEmi. Optimistic early results from use of artificial intelligence/deep learning demonstrate progress and may pave the way for better capabilities in tumor staging, treatment outcome prediction, resulting in improved survival outcomes.

Abstract
BACKGROUND The extra-capsular spread (ECS) of lymph node metastasis (LNM) is a hallmark of aggressive primary tumor phenotype in head and neck cancer (HNC); however, the factors influencing ECS are poorly understood. PATIENTS AND METHODS This was a retrospective study, including 190 cases of oral tongue cancer (OTC), 148 cases of oropharyngeal cancer (OPC) (118 HPV-positive and 30 HPV-negative), and 100 cases of hypopharyngeal cancer (HPC). Tumor dimension, tumor biological variables (lymphovascular/perineural invasion and histologic grade), and LNM variables (LNM number and size) were analyzed according to the presence of ECS using multivariable logistic regression and receiver operating characteristic (ROC) curve analyses. RESULTS LNM variables were significant factors for ECS in all subsites of HNC (p < 0.05), except HPV-positive OPC. In OTC, tumor dimensional variables were significantly related to ECS (p < 0.01). Meanwhile, in OPC and HPC, neither the primary tumor dimension nor the T status were significant factors for ECS occurrence. The predictability of ECS by ROC curve using multiple variables was 0.819 [95% confidence interval: 0.759-0.878] in OTC, 0.687 [0.559-0.815] in HPV-positive OPC, 0.823 [0.642-1.000] in HPV-negative OPC, and 0.907 [0.841-0.973] in HPC. CONCLUSION LNM variables were correlated with ECS occurrence for most HNC subsites, and site-dependent primary tumor characteristics might contribute differentially to the ECS development of LNM in HNC.

Abstract
OBJECTIVES The aims of the study were to determine the predictive imaging findings of extranodal extension (ENE) in metastatic cervical lymph nodes of head and neck squamous cell carcinoma and to investigate the interobserver agreement among radiologists with different experience levels. MATERIALS AND METHODS Patients with cervical lymph node dissection and who had metastatic lymph nodes and preoperative imaging were included. Three radiologists evaluated nodal necrosis, irregular contour, gross invasion, and perinodal fat stranding. They also noted their overall impression regarding the presence of the ENE. Sensitivity, specificity, odds ratios based on logistic regression, and interobserver agreement of ENE status were calculated. RESULTS Of 106 lymph nodes (that met inclusion criteria), 31 had radiologically determined ENE. On pathologic examination, 22 of 31 nodes were positive for ENE. The increasing number of metastatic lymph nodes was associated with the presence of the ENE ( P = 0.010). Irregular contour had the highest sensitivity (78.6%) and gross invasion had the highest specificity (96%) for the determination of the ENE. The radiologists' impression regarding the presence of the pathlogical ENE had 39.3% sensitivity and 82% specificity. Metastatic lymph nodes with a perinodal fat stranding and with the longest diameter of greater than 2 cm were found to be strong predictors of the ENE. The gross invasion demonstrated the highest κ value (0.731) among the evaluated imaging criteria. CONCLUSIONS In the assessment of ENE, the gross invasion had the highest specificity among imaging features and showed the highest interobserver agreement. Perinodal fat stranding and the longest diameter of greater than 2 cm in a metastatic lymph node were the best predictors of the ENE.

Abstract
BACKGROUND Tumor deposits (TDs) are an infrequently mentioned feature of head and neck squamous cell carcinoma (HNSCC) that are currently grouped under extranodal extension (ENE) in the AJCC 8th edition of HNSCC TNM staging. The prognostic implication of TDs in comparison to ENE remains uncertain. METHODS This observational, retrospective, non-randomized study evaluated patients with HNSCC who underwent initial surgical resection, with neck dissection and adjuvant radiotherapy ± chemotherapy. Clinical variables were considered, and statistical analyses were conducted to compare time progression and overall survival (OS) in patients with TDs against those with ENE. RESULTS Of the 71 patients included in the study, 50 were diagnosed with ENE (pN2a-ENE in 38 patients and pN3b-ENE in 12), while 21 had TDs ± ENE. The median time to progression was significantly different based on the presence of ENE or TDs (p = .002) and pN2a-ENE/pN3b-ENE or TDs (p = .007). The three-year OS was 55.7% for the entire group, 60.4% in ENE and 38.4% in TDs (p = .021). The OS difference between the pN2a-ENE, pN3b-ENE, and the TDs group was also significant (p = .05). The hazard ratio between ENE and TDs was Exp (B) 4.341 (p = .044). CONCLUSIONS TDs in HNSCC are associated with a lower OS than ENE, despite intensified adjuvant therapy. Our results confirm a better prognosis for pN2a-ENE vs. pN3b-ENE, and pN3b-ENE vs. TDs. TDs may serve as an indicator of poor prognosis and require separate TNM classification in HNSCC staging. Larger studies are needed to evaluate TDs impact on treatment strategies and outcomes.

Abstract
BACKGROUND. Pathologic extranodal extension (ENE) in metastatic lymph nodes (LNs) has been associated with unfavorable prognosis in patients with non-small cell lung cancer (NSCLC). OBJECTIVE. The purpose of this article was to evaluate the prognostic utility of radiologic ENE and its diagnostic performance in predicting pathologic ENE in patients with NSCLC. METHODS. This retrospective study included 382 patients (mean age, 67 ± 10 [SD] years; 297 men, 85 women) diagnosed with NSCLC and clinical N1 or N2 disease between January 2010 and December 2016. Two thoracic radiologists reviewed staging chest CT examinations to record subjective overall impression for radiologic ENE (no ENE, possible/probable ENE, or unambiguous ENE), reviewing 30 examinations in consensus and the remaining examinations independently. Kaplan-Meier survival analysis and multivariable Cox proportional hazards model were used to evaluate the utility of radiologic ENE in predicting overall survival (OS). Prognostic utility of radiologic ENE was also assessed in patients with clinical N2a disease. In patients who underwent surgery, sensitivity and specificity were determined of radiologic unambiguous ENE in predicting pathologic ENE. RESULTS. The 5-year OS rates for no ENE, possible/probable ENE, and unambiguous ENE were 44.4%, 39.1%, and 20.9% for reader 1 and 45.7%, 36.6%, and 25.6% for reader 2, respectively. Unambiguous ENE was an independent prognostic factor for worse OS (reader 1: adjusted HR, 1.72, p = .008; reader 2: adjusted HR, 1.56, p = .03), whereas possible/probable ENE was not (reader 1: adjusted HR, 1.18, p = .33; reader 2: adjusted HR, 1.21, p = .25). In patients with clinical N2a disease, 5-year OS rate in patients with versus without unambiguous ENE for reader 1 was 22.2% versus 40.6% (p = .59) and for reader 2 was 27.6% versus 41.0% (p = .49). In 203 patients who underwent surgery (66 with pathologic ENE), sensitivity and specificity of radiologic unambiguous ENE for predicting pathologic ENE were 11% and 93% for reader 1 and 23% and 87% for reader 2. CONCLUSION. Radiologic unambiguous ENE was an independent predictor of worse OS in patients with NSCLC. The finding had low sensitivity but high specificity for pathologic ENE. CLINICAL IMPACT. Radiologic ENE may have a role in NSCLC staging workup and treatment selection.

Abstract
Head and neck cancer is notoriously challenging to treat in part because it constitutes an anatomically and biologically diverse group of cancers with heterogeneous prognoses. While treatment can be associated with significant late toxicities, recurrence is often difficult to salvage with poor survival rates and functional morbidity.1,2 Thus, achieving tumor control and cure at the initial diagnosis is the highest priority. Given the differing outcome expectations (even within a specific sub-site like oropharyngeal carcinoma), there has been growing interest in personalizing treatment: de-escalation in selected cancers to decrease the risk of late toxicity without compromising oncologic outcomes, and intensification for more aggressive cancers to improve oncologic outcomes without causing undue toxicity. This risk stratification is increasingly accomplished using biomarkers, which can represent molecular, clinicopathologic, and/or radiologic data. In this review, we will focus on biomarker-driven radiotherapy dose personalization with emphasis on oropharyngeal and nasopharyngeal carcinoma. This radiation personalization is largely performed on the population level by identifying patients with good prognosis via traditional clinicopathologic factors, although there are emerging studies supporting inter-tumor and intra-tumor level personalization via imaging and molecular biomarkers.

Abstract
BACKGROUND Oral tongue squamous cell carcinoma (OTSCC) is a common malignancy of the oral cavity with poor survival rates. The aim of this project is to investigate the relationship between certain histopathological factors such as Worst Pattern of Invasion (WPOI) and Extranodal Extension (ENE) in patients with oral tongue squamous cell carcinoma (OTSCC) who underwent surgical resection at Loyola University Medical Center. METHODS This was a retrospective cohort study at a tertiary care academic medical center. All patients that underwent primary surgical resection of OTSCC between 1/1/2015 and 1/1/2022 were reviewed. Patients were identified using the Cerner CoPath Laboratory Information System. RESULTS A total of 82 patients met inclusion criteria and were included in the study. Higher grades of WPOI (WPOI 5) were not significantly associated with the presence of ENE in our study (P = 0.82), regardless of the presence of major or minor ENE. WPOI 5 was associated with a higher incidence of local recurrence (P = 0.011). CONCLUSIONS Higher grades of WPOI were not found to correlate with the presence of ENE, a common histopathological factor that is used as an important prognostic indicator in OTSCC. It is important for clinicians to consider these factors separately when determining whether a patient is high-risk and would benefit from aggressive multimodal treatment.

Abstract
BACKGROUND Whether extra-nodal extension (ENE+) and surgical margin positivity (margin+) are poor prognostic factors in HPV-associated (HPV+) oropharyngeal carcinoma (OPC) remains uncertain. RESULTS Our study evaluated if microscopic ENE+ and/or margin+ are associated poorer recurrence free survival (RFS) and overall survival (OS) in HPV+ OPC. Patients were classified as high risk (ENE+ and/or margin+) or low risk (ENE- and margins-). Of a total of 176 patients HPV+ OPC, 81 underwent primary surgery and dad data on ENE and margin status. There was no statistically significant difference in RFS (p = 0.35) or OS (p = 0.13) for high-risk versus low-risk groups. Ongoing smoking (p = 0.023), alcohol use (p = 0.044) and advanced stage (p = 0.019) were associated with higher risk of recurrence. Only advanced stage (p-value <0.0001) was associated poorer overall survival. CONCLUSIONS The presence of ENE+ and/or margin+ was not an independent predictor of poor RFS or OS in HPV+ OPC.

Abstract
Soft tissue deposits, also known as tumour deposits (TDs), have not been studied well in head and neck squamous cell carcinoma (HNSCC) and are not included in any of the staging systems or treatment guidelines. The aim of this systematic review was to determine the prevalence and prognostic implications of TDs in patients with HNSCC. This systematic review of the literature was conducted following the PRISMA guidelines. The PubMed, Embase, and Scopus electronic databases were searched for relevant studies, from inception to August 2022. Although 14 studies qualified for inclusion, only eight were finally included in the review due to the considerable overlap of patients in several studies. Data from 7127 patients were analysed. The pooled prevalence of TDs was 21% (95% confidence interval (CI) 9-33%). The presence of TDs was adversely associated with overall survival and disease-free survival, with hazard ratios of 2.08 (95% CI 1.60-2.70) and 2.56 (95% CI 1.97-3.32), respectively. TDs are detected in a significant number of patients with HNSCC and adversely affect survival. Longitudinal prospective studies are needed to evaluate the prognostic implications of TDs in HNSCC for their potential role in cancer staging and adjuvant treatment planning.

Abstract
The treatment of HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) continues to evolve as multiple ongoing and recently completed clinical trials investigate the role of surgery, radiation therapy, chemotherapy, and immunotherapy. Current trials are investigating transoral robotic surgery (TORS) in treatment de-escalation protocols in an effort to optimize quality of life, while maintaining historical survival rates. The advantage of TORS is its minimally invasive approach to primary resection of the tumor as well as valuable pathologic staging. The ORATOR trial reported poorer quality of life in patients treated with TORS compared to primary radiotherapy though this was not a clinically meaningful difference. The recently published ECOG 3311 trial showed that surgery can be used to safely de-escalate the adjuvant radiation dose to 50 Gy in intermediate-risk patients. In this review, we summarize and discuss the past and current clinical trials involving surgery in the treatment of HPV-positive OPSCC.

Abstract
Extranodal extension (ENE) is a significant prognostic factor for human papilloma virus (HPV)-negative head and neck squamous cell carcinoma and is incorporated into AJCC 8th edition pN stage. It remains controversial whether ENE or the degree of ENE is prognostically relevant in HPV-positive oropharyngeal squamous cell carcinoma (OPSCC). A detailed clinicopathologic review was conducted in a large retrospective cohort of 232 surgically treated patients with HPV-positive OPSCC and nodal metastasis. Fifty-six patients (24%) had nodal metastasis with ENE. The median vertical extent of ENE was 2.9 mm (range 0.2-20.3 mm), and the median horizontal span of ENE was 2.5 mm (range: 0.3-14.0 mm). Comparing with patients without ENE, those with ENE were associated with a higher number of positive lymph nodes, lymphovascular invasion, perineural invasion, adjuvant chemotherapy, larger primary tumor size, and shorter follow up period. Patients with ENE had shortened overall survival (OS), disease specific survival (DSS), disease free survival (DFS), distant metastasis free survival (DMFS), and regional recurrence free survival (RRFS) on univariate survival analysis. The 5-year OS, DSS, and DFS were 95%, 97%, and 90% respectively for the group without ENE, and 64%, 71%, and 65% respectively for the group with ENE. On Multivariate survival analysis, the presence of ENE was an independent adverse prognostic factor for OS, DSS, and DFS. Additionally, major ENE defined as a vertical extent of ≥4 mm or irregular soft tissue deposit independently predicted shortened OS, DSS, and RFS. In conclusion, the presence of ENE, in particular major ENE, is an independent prognostic factor in HPV-positive OPSCC. Therefore, we propose to document the presence and extent of ENE for these tumors. Consideration may be given for AJCC 9th edition to include ENE into pN stage of HPV-positive OPSCC.

Abstract
BACKGROUND Extranodal extension (ENE) in lymph node metastases is one of the most important prognostic factors in head and neck squamous cell carcinomas. Studies have shown inconsistency among pathologists in the assessment of ENE. The aims of this study were: (1) to determine the interrater and intrarater reliability and agreement in the assessment of ENE among Danish pathologists and (2) to test if a standardized assessment method may increase interrater agreement. METHODS Four Danish head and neck pathologists assessed ENE presence or absence in 120 histological slides from lymph nodes with oropharyngeal squamous cell carcinoma metastases (first round). Subsequently, guidelines were introduced to the pathologists and a new assessment was performed (second round). Finally, two of the pathologists assessed the slides to determine intrarater reliability and agreement (third round). RESULTS Interrater kappa coefficients varied between 0.57 and 0.67 in the first round and between 0.59 and 0.72 in the second round. The intrarater agreement between round 2 and 3 was 0.88 for pathologist 1 and 0.92 for pathologist 2 with resulting kappa coefficients of 0.76 (95% CI 0.64-0.88) and 0.84 (95% CI 0.74-0.94), respectively. CONCLUSION We found a moderate level of reliability and agreement among pathologists for ENE in lymph node metastases from oropharyngeal squamous cell carcinomas. The intrarater reliability and agreement was generally higher than interrater measures. Interrater agreement was slightly improved by standardized assessment.

Abstract
OBJECTIVE To analyze the prognostic significance of microscopic vs macroscopic extranodal extension and to assess the impact of chemoradiation on overall survival among patients with oral cavity squamous cell carcinoma and varying degrees of extranodal extension. METHODS Utilizing the National Cancer Database, we performed a retrospective cohort study of 7975 patients with oral cavity squamous cell carcinoma and varying degrees of extranodal extension who underwent primary surgical intervention. Propensity-score matched models following Cox regression analyses allowed us to assess the impact of adjuvant radiation alone vs adjuvant chemoradiation on overall survival in patients with microscopic extranodal extension and macroscopic extranodal extension. RESULTS 7975 patients with oral cavity squamous cell carcinoma were included in the final analysis. Within this cohort, 25.4% had microscopic extranodal extension and 5.2% had macroscopic extranodal extension. On univariate analysis, we found that microscopic and macroscopic extranodal extension were associated with decreased overall survival when compared to those with positive nodes without extranodal extension (HR = 1.67; 95% CI 1.56, 1.79 and HR = 1.88; 95% CI 1.66, 2.14, respectively). On multivariate analysis after propensity-score matching, we found no significant difference in overall survival in patients who received adjuvant radiation alone vs. adjuvant chemoradiation for both microscopic and macroscopic extranodal extension. CONCLUSION Our data suggest that microscopic extranodal extension in oral cavity squamous cell carcinoma is associated with worse overall survival than patients without extranodal extension following primary surgical intervention with neck dissection. The results of this study also suggest that the addition of chemotherapy to adjuvant radiation may not provide a significant survival benefit in patients with oral cavity squamous cell carcinoma with microscopic and macroscopic extranodal extension. Comprehensive assessment of the benefits of adjuvant chemoradiation in the setting of microscopic vs macroscopic extranodal extension would need to be studied in a randomized controlled trial.

Abstract
Robotic systems for head and neck surgery are at different stages of technical development and clinical application. Currently, robotic systems are predominantly used for transoral surgery of the pharynx and larynx. Robotic surgery of the neck, the thyroid, and the middle and inner ear is much less common; however, some oncological and functional outcomes have been reported. This article provides an overview of the current state of robot-assisted head and neck surgery with a special emphasis on patient benefit and postoperative quality of life (QoL). The focus is placed on the role of transoral robotic surgery (TORS) for the resection of oropharyngeal carcinomas. For this application, reported long-term outcomes show functional post-operative advantages for selected oropharyngeal cancer patients after TORS compared to open surgery and primary radiotherapy. Since TORS also plays a significant role in the context of potential therapy de-escalation for HPV-positive oropharyngeal cancer patients, ongoing trials are presented. Regarding the evaluation of the therapeutic benefit and the QoL of cancer patients, special attention has to be paid to the large degree of variability of individual patients' preferences. Influencing factors and tools for a detailed assessment of QoL parameters are therefore detailed at the beginning of this article. Notably, while some robotic systems for ear and skull base surgery are being developed in Europe, TORS systems are mainly used in North America and Asia. In Europe and Germany in particular, transoral laser microsurgery (TLM) is a well-established technology for transoral tumor resection. Future trials comparing TORS and TLM with detailed investigation of QoL parameters are therefore warranted and might contribute to identifying suitable fields for the application of the different techniques.

Abstract
PURPOSE To determine the rate of detectability of ctHPVDNA after surgery but before adjuvant therapy in patients with HPV-associated oropharyngeal squamous cell carcinoma (HPV(+)OPSCC) and to investigate whether detectable ctHPVDNA at this time point may be associated with risk of recurrence. METHODS AND MATERIALS Prospectively collected samples from patients with OPSCC were examined in a blinded fashion using a multi-analyte PCR assay. 45 samples were collected from HPV(+)OPSCC patients pre-op (prior to any treatment), and 159 samples post-op (before or at the start of adjuvant RT). Samples were identified via the radiation oncology biobank or via participation in a clinical trial. RT consisted of 60 Gy +/- cisplatin or de-escalation (30 Gy to 36 Gy in 20 b.i.d. fractions + docetaxel). 32 patients had paired samples available pre and post-op for the primary analysis. Additional exploratory analyses including associations of patient and tumor characteristics with recurrence were assessed using Cox proportional hazards models for all 159 post-op samples.. Detectability of ctHPVDNA was compared across groups utilizing logistic regression. Estimates of recurrence free survival (RFS) were made using Kaplan-Meier (KM). RESULTS In a paired analysis of 32 pre and post-op timepoints, 94% of patients had detectable ctHPVDNA pre-op and 41% post-op. RFS at 18 months was 83% (95% CI: 47-95%) for patients with detectable post-op ctHPVDNA compared to 100% for patients with undetectable post-op ctHPVDNA (p=.094).In an exploratory analysis of non-paired post-op samples, ctHPVDNA was detectable in 26% (41 of 159) of patients (median of 22 days post-op). Age (1.06, p=0.025), LVSI (OR 3.17, p=0.011) and ENE (OR=5.67, p=0.001) were associated with detectable ctHPVDNA after surgery. Detectable post-op ctHPVDNA was significantly associated with RFS (p<0.001). CONCLUSION Amongst patients with detectable pre-op ctHPVDNA, a significant proportion have detectable post-op ctHPVDNA in paired post-op samples, collected prior to the initiation of adjuvant radiation therapy. Future prospective study is warranted to investigate the association of detectable post-op ctHPVDNA with recurrence, including in comparison to established clinical and pathologic risk factors.

Abstract
Background: Head and neck squamous cell carcinoma (HNSCC) was the
seventh most common cancer worldwide in 2018. Lymphatic metastasis (LM) is
closely related to HNSCC prognosis and recurrence. However, the underlying
mechanism of LM remains unclear. Therefore, this study aimed to identify the key
genes in the LM of HNSCC. Methods: We used The Cancer Genome Atlas
(TCGA) to identify differentially expressed genes (DEGs) between LM and non-LM
cases. A random forest model, the Search Tool for the Retrieval of Interacting
Genes, Cytoscape, and cytoHubba were used to identify hub genes among DEGs,
including KRT20 (Cytokeratins 20). We analyzed the survival of KRT20 in TCGA,
and we overexpressed KRT20 in HNSCC cell lines to investigate its effects on
migration and invasion. We also correlated the expression of KRT20 in HNSCC
tissue microarrays with survival and clinicopathological features.
Results: We identified 243 DEGs—143 upregulated genes and 100
downregulated genes. Further analysis revealed that KRT20 is a potential key
gene associated with LM and overall survival rates among patients with HNSCC.
Overexpression of KRT20 increased the migration and invasion ability of HNSCC
cell lines Tu686 and FD-LSC-1. Tissue microarray studies demonstrated an
overexpression of KRT20 among N1+ patients (including N1-N3 patients). Survival
analysis results and the clinicopathological features of HNSCC tissue
microarrays were consistent with our analysis of TCGA. Thus, a high KRT20
expression level might suggest an adverse HNSCC prognosis. Our gene set
enrichment analysis showed that KRT20 participates in many metabolic pathways,
including those related to tumorigenesis and cancer development.
Conclusions: We propose that KRT20 may be a key gene in HNSCC
with LM.

Abstract
BACKGROUND Adjuvant guidelines in surgically resected p16+ oropharyngeal carcinoma (OPC) with positive surgical margins (PSM) or extranodal extension (ENE) are based on randomized controlled trials predating p16 status. It remains unclear if adjuvant chemotherapy is necessary in p16+ patients with these features. METHODS The National Cancer Database was used to identify cases of nonmetastatic p16+ OPC diagnosed from 2010 to 2017. Patients treated with surgical resection followed by adjuvant radiation (aRT) or adjuvant chemoradiation (aCRT) were eligible for analysis. RESULTS A total of 14 071 patients were eligible for analysis. Overall survival (OS) was not statistically different between aRT and aCRT in patients with PSM (hazard ratio (HR) 0.84, 95% confidence interval (CI) 0.56-1.28), ENE (HR 0.93, 95% CI 0.69-1.27) or both (HR 0.73, 95% CI 0.41-1.31). CONCLUSIONS In patients with p16+ OPC with ENE, PSM, or both, adding chemotherapy to aRT was not associated with improved OS.

Abstract
BACKGROUND Extranodal extension (ENE) is a crucial prognostic factor of oral squamous cell carcinoma (OSCC). However, the role of ENE in regional recurrence (rENE) remains unclear. The purpose of our study is to assess the salvage outcome according to the presence of rENE in oral cancer patients with isolated nodal recurrence. METHODS Oral cancer patients diagnosed with isolated nodal recurrence at the National Taiwan University Hospital between January 2010 and December 2015 were reviewed. All patients were classified into two groups: with and without rENE. The treatment included salvage neck dissection (ND) ± metronomic chemotherapy, salvage ND and radiation (RT)/concurrent chemoradiation (CCRT), Salvage RT/CCRT alone, metronomic chemotherapy, or supportive care. RESULTS We analyzed 198 patients, 156 with rENE and 42 without rENE. rENE presented more frequently in patients with initial ENE+ (OR = 3.17, p = 0.04), prior RT+ (OR = 2.96, p = 0.02), initial N2/N3 (OR = 2.76, p = 0.01), and recurrent LN size >1.5 cm (OR = 2.33, p = 0.03). The extent of rENE were also significantly different in these patients. The 2-year disease-free survival for patients with and without rENE were 15.7% and 31.7%, respectively (p = 0.002). The 2-year overall survival for patients with and without rENE were 19.6% and 43.9%, respectively (p = 0.004). For patients without rENE, those received salvage ND had better survival outcome (p < 0.001). By contrast, for patients with rENE, those received salvage RT/CCRT had better survival outcome (p < 0.001). CONCLUSION The rENE is frequently present (78.79%) in OSCC patients with isolated nodal recurrence. Individualized treatment modalities based on the presence of rENE should be recommended to achieve better salvage outcomes.

Abstract
INTRODUCTION Although salvage surgery (SS) is considered the best curative choice in recurrent head and neck cancer, the identification of patients who can benefit the most from this treatment is challenging. METHODS We systematically reviewed the prognostic role of pre- and post-surgery factors in patients undergoing SS for recurrent head and neck cancer (oral cavity, oropharynx, hypopharynx, and larynx). RESULTS Twenty-five studies met the inclusion criteria out of 1280 screened citations. Pre-surgery factors significantly associated with worse overall survival were age>60 years, advanced initial stage, early recurrence, and regional recurrence; no heterogeneity between study emerged. Among post- surgery factors, worse survival emerged for positive surgical margins, extracapsular extension and perineural invasion. CONCLUSION The identification of pre-surgery factors associated with poor outcomes may help the selection of the best candidate to SS; alternative treatments should be considered for high-risk patients. Post-surgery predictors of worse prognosis may guide clinicians in tailoring patients' surveillance.

Abstract
OBJECTIVE Pathologic extranodal extension (ENE) is an important adverse feature for human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC), but the prognostic significance of microscopic ENE (ENEmi) and role of adjuvant concurrent chemoradiation (CRT) for ENEmi remain unclear. This study evaluates (1) the prognostic significance of ENEmi in HPV-negative HNSCC and (2) whether adjuvant CRT is associated with improved overall survival (OS) for these patients. STUDY DESIGN Retrospective cohort study. SETTING Commission on Cancer (CoC)-accredited facilities. METHODS This retrospective cohort study included patients in the National Cancer Database from 2009 to 2015 with pathologic node-positive (pN+) HPV-negative HNSCC with either pathologic ENEmi or no ENE who had undergone margin-negative surgery. The association of ENEmi with OS was evaluated using Cox proportional hazard analyses. Analyses were repeated in patients with ENEmi receiving adjuvant therapy to evaluate the association of adjuvant CRT with OS. RESULTS We included 5483 patients with pN+ HPV-negative HNSCC, of whom 24% had ENEmi. On multivariable analysis, ENEmi was associated with decreased OS relative to no ENE (adjusted hazard ratio [aHR], 1.43; 95% CI, 1.28-1.59). Among patients with ENEmi who received ≥60 Gy of adjuvant radiation therapy (RT) (n = 617), adjuvant CRT was not associated with improved OS relative to RT (aHR, 0.91; 95% CI, 0.66-1.27). CONCLUSION For patients with HPV-negative HNSCC, pN+ with ENEmi is associated with worse OS than pN+ without ENE. However, for patients with ENEmi, concurrent CRT is not associated with improved OS relative to RT. The optimal adjuvant paradigm for ENEmi requires additional investigation.

Abstract
Introduction Extracapsular extension (ECE) in the lymph nodes for patients with head and neck cancer has been found to be a poor prognostic factor in multiple studies. The purpose of the study is to evaluate the predictive factors for ECE on computer tomography (CT) imaging for patients undergoing surgery and to analyze outcomes. Methods We conducted an Institutional Review Board-approved, Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective review of 82 patients with biopsy-proven squamous cell carcinomas of the head and neck who underwent definitive surgery without neoadjuvant chemotherapy or radiation therapy. CT scans were evaluated for the level of involvement, size, and presence or absence of central necrosis. Extracapsular extension in lymph nodes on the postoperative pathology was correlated with the central necrosis in the lymph nodes appreciated on the CT neck with contrast. Survival estimates were evaluated using the Kaplan-Meier test. Results ECE on postoperative pathology was seen in 74.07% of patients who had evidence of central necrosis in lymph nodes on preoperative CT neck compared to 46.43% without CT necrosis (p=0.013). The incidence of ECE is higher in poorly differentiated tumors and also nodal stages >N2c at presentation. Patents with ECE had inferior disease-free and overall survival (OS). Conclusions Our results reveal that patients with necrosis on CT and with moderately to poorly differentiated tumors have a high incidence of extracapsular extension. There was no difference in local control (LC) between the groups of patients, but the OS was inferior in patients with ECE. Predicting extracapsular extension upfront helps to formulate the appropriate treatment. We propose to study additional chemotherapy to improve outcomes in patients with positive extracapsular extension.

Abstract
The aim of this paper is to define the pre-treatment radiological characteristics of oropharyngeal squamous cell carcinoma (OPSCC) using morphological and non-morphological magnetic resonance imaging (MRI), based on HPV status, in a single-institution cohort. In total, 100 patients affected by OPSCC were prospectively enrolled in the present study. All patients underwent 1.5T MR with standard sequences, including diffusion-weighted imaging with and intravoxel incoherent motion (IVIM-DWI) technique and a dynamic contrast-enhanced (DCE) MRI. For all patients, human papillomavirus (HPV) status was available. No statistically significant differences in the volume of primary tumors (PTs) and lymph nodes (LNs) were observed based on HPV status. When comparing the two patient groups, no significant differences were found for the PT radiologic characteristics (presence of well-defined borders, exophytic growth, ulceration, and necrosis) and LN morphology (solid/cystic/necrotic). Tumor subsite, smoking status, and alcohol intake significantly differed based on HPV status, as well as ADC and Dt values of both PTs and LNs. We detected no significant difference in DCE-MRI parameters by HPV status. Based on a multivariate logistic regression model, the combination of clinical factors, such as tumor subsite and alcohol habits, with the perfusion-free diffusion coefficient Dt of LNs, may help to accurately discriminate OPSCC by HPV status.

Abstract
Objective The recent introduction of 3D exoscopic surgery has allowed interesting technical improvements in head and neck surgery resulting in technical solutions that are also applicable to neck dissection. The aim is to replace robotic surgery while minimising the costs of the procedure. Methods Based on these considerations, we conducted a preclinical investigation in the cadaver lab focused on approaching conventional neck dissection using a retroauricular incision, and evalute the applications and usefulness of the Storz 3D Exoscopic System at different stages of the surgical procedure. The acronym RAND-3D (3D exoscopic surgery) was coined to describe the application of this optical tool in neck dissection. Results The current study in the cadaver lab indicates that RAND-3D is an acceptable alternative operating technique in performing neck dissection by a retroauricular approach. Technically feasible and safe, this technique assures a complete compartment-oriented dissection without damaging major vascular or nervous structures. Conclusions This approach can be used in selected cases with a clear cosmetic benefit and represents a valid alternative to endoscopic- and robotic-assisted neck dissection.

Abstract
OBJECTIVE To analyze the patterns, risk factors, and salvage outcomes for locoregional recurrences (LRR) after treatment with transoral robotic surgery (TORS) for HPV-associated oropharyngeal squamous cell carcinoma (HPV+ OPSCC). STUDY DESIGN Retrospective analysis of HPV+ OPSCC patients completing primary TORS, neck dissection, and NCCN-guideline-compliant adjuvant therapy at a single institution from 2007 to 2017. METHODS Features associated with LRR, detailed patterns of LRR, and outcomes of salvage therapy were analyzed. Disease-free survival (DFS) and overall survival (OS) were calculated for subgroups of patients receiving distinct adjuvant treatments. RESULTS Of 541 patients who completed guideline-indicated therapy, the estimated 5-year LRR rate was 4.5%. There were no identifiable clinical or pathologic features associated with LRR. Compared to patients not receiving adjuvant therapy, those who received indicated adjuvant radiation alone had a lower risk of LRR (HR 0.28, 95% CI [0.09-0.83], P = .023), but there was no difference in DFS (P = .21) and OS (P = .86) between adjuvant therapy groups. The 5-year OS for patients who developed LRR was 67.1% vs. 93.9% for those without LRR (P < .001). Patients who initially received adjuvant chemoradiation and those suffering local, in-field, and/or retropharyngeal node recurrences had decreased disease control after salvage therapy. CONCLUSION LRR rates are low for HPV+ OPSCCs completing TORS and guideline-compliant adjuvant therapy. Patients without indication for adjuvant therapy more often suffer LRR, but these recurrences are generally controllable by salvage therapy. Improved understanding of the patterns of recurrence most amenable to salvage therapy may guide treatment decisions, counseling, and adjuvant therapy de-escalation trials.

Abstract
Importance Regional lymph node metastasis remains an important prognostic factor in patients with oropharyngeal squamous cell carcinoma (OPSCC). Although survival among patients with regional metastasis in human papillomavirus (HPV)-related OPSCC is more favorable compared with patients who are HPV negative, prognostic variables associated with failure in patients with single-node metastasis are not known. Objective To evaluate recurrence and survival in patients with HPV-related OPSCC with single-lymph node metastasis treated with transoral surgery. Design, Setting, and Participants A retrospective cohort study was conducted of 207 adults with newly diagnosed p16-positive OPSCC and pathology-confirmed single-node disease who underwent surgical resection with or without adjuvant therapy at 2 tertiary academic medical centers from January 1, 2007, to December 31, 2016. Statistical analysis was performed from September 1, 2018, to September 1, 2020. Interventions Surgery alone (n = 59), surgery with adjuvant radiation (n = 75), or surgery with adjuvant chemoradiation (n = 73). Main Outcomes and Measures The primary outcome was regional recurrence. Secondary outcomes included overall survival, any recurrence, and identification of factors associated with regional recurrence and overall survival. Results Among 207 patients, 178 (86%) were men, with a median age of 57 years (range, 35-82 years) at the time of surgery. Median follow-up was 36.2 months (range, 7-127 months). Regional recurrence occurred in 11 patients (5%). Of these, 1 patient (9%) was lost to follow-up after diagnosis, 1 (9%) was treated with palliative chemotherapy, and 9 (82%) were treated with curative intent. Ultimately, 7 patients received successful salvage treatment, and 3 died with disease. Overall, there were 21 patients (10%) with any recurrence, with 4 patients (19%) experiencing local recurrence, 11 (52%) experiencing regional recurrence, and 6 (29%) experiencing distant metastasis. The 5-year overall survival was 95% (95% CI, 89%-98%) for all patients. Older age (odds ratio [OR], 1.2; 95% CI, 1.1-1.2), advanced T stage (OR, 3.5; 95% CI, 0.9-14.0), and positive margins (OR, 10.9; 95% CI, 1.8-67.5) were associated with increased regional recurrence. Extranodal extension (OR, 0.2; 95% CI, 0.04-0.8), lymph node size greater than 3 cm (OR, 0.2; 95% CI, 0.1-0.7), and adjuvant therapy (OR, 0.08; 95% CI, 0.02-0.4) were associated with decreased regional recurrence. Advanced comorbidities (hazard ratio, 6.20; 95% CI, 1.4-27.7), lymphovascular invasion (hazard ratio, 4.7; 95% CI, 1.0-21.2), and regional recurrence (hazard ratio, 16.0; 95% CI, 3.1-82.0) were associated with worse overall survival. Conclusions and Relevance The findings of this cohort study suggest that patients with HPV-related OPSCC and single-node disease undergoing surgical resection with or without adjuvant treatment have excellent survival. Adjuvant therapy appears to improve regional control. Among patients with regional recurrence of OPSCC, there is a high rate of successful salvage treatment.

Abstract
BACKGROUND The impact of close surgical margins on oncologic outcomes in HPV-related oropharyngeal squamous cell carcinoma (HPV + OPSCC) is unclear. METHODS Retrospective case series including patients undergoing single modality transoral robotic surgery (TORS) for HPV + OPSCC at three academic medical centers from 2010 to 2019. Outcomes were compared between patients with close surgical margins (<1 mm or requiring re-resection) and clear margins using the Kaplan-Meier method. RESULTS Ninety-nine patients were included (median follow-up 21 months, range 6-121). Final margins were close in 22 (22.2%) patients, clear in 75 (75.8%), and positive in two (2.0%). Eight patients (8.1%) recurred, including two local recurrences (2.0%). Four patients died during the study period (4.0%). Local control (p = 0.470), disease-free survival (p = 0.513), and overall survival (p = 0.064) did not differ between patients with close and clear margins. CONCLUSIONS Patients with close surgical margins after TORS for HPV + OPSCC without concurrent indications for adjuvant therapy may be considered for observation alone.

Abstract
Tumor breaching the capsule of a lymph node is termed extranodal extension (ENE). It reflects aggressiveness of a tumor, creates anatomic challenges for disease clearance, and increases the risk of distant metastasis. Extranodal extension can be assessed on a pathology specimen, by radiology studies, and by clinical examination. Presence of ENE in a pathology specimen has long been considered a high-risk feature of disease progression and would ordinarily benefit from the addition of chemotherapy to adjuvant radiotherapy. Although the eighth edition of the Union for International Cancer Control/American Joint Committee on Cancer stage classification dichotomizes pathologic ENE according to its presence or absence, emerging evidence suggests that the extent of a pathologic ENE may provide additional value for risk stratification to guide adjuvant therapy. Recent data suggest that the prognostic importance of pathologic ENE is also applicable for HPV-associated head and neck squamous cell carcinoma. In addition, compelling data demonstrate that indisputable radiologic ENE is a powerful risk stratification tool to identify patients at high risk for treatment failure, especially distant metastasis, applicable for both HPV-positive and HPV-negative head and neck squamous cell carcinoma. However, the definition and taxonomy of radiologic ENE requires standardization. The goal of this review is to clarify the contemporary understanding of the prognostic implications of ENE in head and neck squamous cell carcinoma, present the nuances of what is presently known and unknown, and elucidate how to classify ENE pathologically and radiologically with an understanding of the strengths and weaknesses of each approach. Finally, with the development of several risk stratification methods, the relative role of ENE and other prognostic schema will be explored.

Abstract
BACKGROUND Matted nodes in human papillomavirus (HPV)-mediated oropharyngeal squamous cell carcinoma (OPC) is an independent predictor of distant metastases and decreased overall survival. We aimed to classify imaging patterns of metastatic lymphadenopathy, analyze our classification system for reproducibility, and assess its prognostic value. METHODS The metastatic lymphadenopathy was classified based on radiological characteristics for 216 patients with HPV-mediated OPC. Patient outcomes were compared and inter-rater reliability was calculated. RESULTS The presence of ≥3 abutting lymph nodes with imaging features of surrounding extranodal extension (ENE), one subtype of matted nodes, was associated with worse 5-year overall survival, overall recurrence-free survival, regional recurrence-free survival, and distant recurrence-free survival (p ≤ 0.03). Other patterns were not significantly associated with outcome measures. Overall inter-rater agreement was substantial (κ = 0.73). CONCLUSION One subtype of matted nodes defined by ≥3 abutting lymph nodes with imaging features of surrounding ENE is the radiological marker of worst prognosis.

Cancer 2021; 127:1590-1597. [PMID: 33595897 DOI: 10.1002/cncr.33414] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 10/23/2020] [Accepted: 10/28/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND Modern disease staging systems have restructured human papillomavirus (HPV)-negative (HPV-) and HPV-positive (HPV+) oropharyngeal carcinoma (OPC) into distinct pathologic nodal systems. Given that quantitative lymph node (LN) burden is the dominant prognostic factor in most head and neck cancers, we investigated whether HPV- and HPV+ OPC warrant divergent pathologic nodal classification. METHODS Multivariable Cox regression models of OPC surgical patients identified via U.S. cancer registry data were constructed to determine associations between survival and nodal characteristics. Nonlinear associations between metastatic LN number and survival were modeled with restricted cubic splines. Recursive partitioning analysis (RPA) was used to derive unbiased nodal schema. RESULTS Mortality risk escalated continuously with each successive positive LN in both OPC subtypes, with analogous slope. Survival hazard increased by 18.5% (hazard ratio [HR], 1.19 [95% CI, 1.16-1.21]; P < .001) and 19.1% (HR, 1.19 [95% CI, 1.17-1.21]; P < .001), with each added positive LN for HPV- and HPV+ OPC, respectively, up to identical change points of 5 positive LNs. Extranodal extension (ENE) was an independent predictor of HPV- OPC (HR, 1.55 [95% CI, 1.20-1.99]; P < .001) and HPV+ OPC (HR 1.73 [95% CI, 1.36-2.20]; P < .001) mortality. In RPA for both diseases, metastatic LN was the principal nodal covariate driving survival, with ENE as a secondary determinant. Given the similarities across analyses, we propose a concise, unifying HPV-/HPV+ OPC pathologic nodal classification schema: N1, 1-5 LN+/ENE-; N2, 1-5 LN+/ENE+; N3, >5 LN+. CONCLUSION HPV- and HPV+ OPC exhibit parallel relationships between nodal characteristics and relative mortality. In both diseases, metastatic LN number represents the principal nodal covariate governing survival, with ENE being an influential secondary element. A consolidated OPC pathologic nodal staging system that is based on these covariates may best convey prognosis. LAY SUMMARY The current nodal staging system for oropharyngeal carcinoma (OPC) has divided human papillomavirus (HPV)-negative (HPV-) and HPV-positive (HPV+) OPC into distinct systems that rely upon criteria that establish them as separate entities, a complexity that may undermine the core objective of staging schema to clearly communicate prognosis. Our large-scale analysis revealed that HPV- and HPV+ pathologic nodal staging systems in fact mirror each other. Multiple analyses produced conspicuously similar nodal staging systems, with metastatic lymph node number and extranodal extension delineating the highest risk groups that shape prognosis. We propose unifying HPV- and HPV+ nodal systems to best streamline prognostication and maximize staging accuracy.

PET/CT Poorly Predicts AJCC 8th Edition Pathologic Staging in HPV-Related Oropharyngeal Cancer. Laryngoscope 2021; 131:1535-1541. [PMID: 33428218 DOI: 10.1002/lary.29366] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 12/10/2020] [Accepted: 12/24/2020] [Indexed: 11/10/2022]
Abstract
OBJECTIVE The American Joint Committee on Cancer (AJCC) 8th edition introduced distinct clinical and pathological staging paradigms for human papilloma virus positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC). Treatment planning for OPSCC often utilizes positron emission tomography/computed tomography (PET/CT) to assess clinical stage. We hypothesize that PET/CT will accurately predict final pathologic AJCC 8th edition staging in patients with HPV+ OPSCC. METHODS All patients with primary HPV+ OPSCC with preoperative PET/CT who underwent transoral robotic surgery and neck dissection between 2011 and 2017 were identified. Data were collected via chart review. Two neuroradiologists performed blinded re-evaluation of all scans. Primary tumor size and cervical nodal disease characteristics were recorded and TNM staging was extrapolated. Cohen's kappa statistic was used to assess interrater reliability. Test for symmetry was performed to analyze discordance between radiologic and pathologic staging. RESULTS Forty-nine patients met inclusion criteria. Interrater reliability was substantial between radiologists for nodal (N) and overall staging (OS) (κ = 0.715 and 0.715). Radiologist A review resulted in identical OS for 67% of patients, overstaging for 31%, and understaging for 2%. Radiologist B review resulted in 61% identical OS, 39% overstaging, and 0% understaging. In misclassified cases, the test of symmetry shows strong bias toward overstaging N stage and OS (P < .001). Radiologic interpretation of extracapsular extension showed poor interrater reliability (κ = 0.403) and poor accuracy. CONCLUSION PET/CT predicts a higher nodal and overall stage than pathologic staging. PET/CT should not be relied upon for initial tumor staging, as increased FDG uptake is not specific for nodal metastases. PET/CT is shown to be a poor predictor of ECE.

Abstract
This article outlines the ways that transoral robotic surgery and transoral laser microsurgery relate to treatment de-escalation in the treatment of head and neck cancer. Treatment de-escalation has particular importance in context of human papillomavirus-related oropharynx squamous cell carcinoma, which responds well to therapy but leaves many survivors with decades of treatment-related sequelae. We compare these less invasive transoral approaches with previously used open approaches to the oropharynx. We discuss the topic of treatment de-escalation in human papillomavirus-related disease and outline completed and ongoing clinical trials investigating the choice of primary treatment modality and de-escalation of adjuvant therapy.

Abstract
BACKGROUND The prognostic significance of various histopathologic lymph node-based biomarkers in oral squamous cell carcinoma (OSCC) needs further evaluation. METHODS Retrospective analysis of 212 OSCC patients with regional metastasis to determine the association of extranodal extension (ENE), extent of ENE, size of metastatic deposit, lymph node yield (LNY), lymph node ratio (LNR), and topography of involvement with survival outcomes. RESULTS The presence of ENE, larger nodal deposit, higher pN stage, lymph nodes in the lower levels, and patients who did not receive adjuvant treatment had poor disease-free survival (DFS). In addition, more positive nodes and high LNR showed worse overall survival (OS). ENE beyond 5 mm resulted in poorer outcomes. Larger sizes of metastatic deposit predisposed to ENE. Multivariate analyses showed only lower level of neck involvement to affect both DFS and OS. CONCLUSIONS Lymph node metastasis to lower levels and other lymph node characteristics affect prognosis and must be considered in the evolution of staging systems for OSCC.

Abstract
Salvage surgery after failed organ preservation treatment offers challenges for both the patient and the surgeon. The outcome is often uncertain and even today, 5‐year overall survival does not exceed 50 per cent. The chemoradiotherapy induced toxicity asks for meticulous discussion and planning in a multidisciplinary manner in a changing environment of increasing incidence of human papillomavirus induced oropharyngeal tumours, evolving surgical techniques and patient participation. Herein, we discuss the latest literature on salvage surgery and the need for identifying the proper prognosticators to ensure for an optimal treatment plan in potentially salvageable patients.

Abstract
To investigate the prognostic significance of the stratification of extranodal extension (ENE) into ENE minor (ENEmi, up to 2mm) and ENE major (ENEma, over 2mm) in non-HPV-related squamous cell cancers of the head and neck, we retrospectively reviewed microscopic slides from neck dissection specimens of ENE-positive patients and subcategorised them into ENEmi and ENEma. We then compared the two groups in terms of overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). Forty-four patients with pathologically positive necks had ENE in the histological report. Twenty-six had ENEmi and 18 ENEma. The three-year OS was 46% in the ENEmi group and 38.9% in the ENEma group. DSS and DFS were 80.8% and 80.8%, respectively, in the ENEmi group and 61.1% and 77.8%, respectively, in the ENEma group. None of the comparisons revealed any statistically significant difference. The results of our survival analysis seem to show a trend towards better survival rates in the ENEmi group, particularly regarding OS. Nonetheless, extension of the tumour outside the lymph node capsule by more than 2mm was not found to be significantly associated with any of the explored survival outcomes.

Abstract
Extranodal extension (ENE) is a very strong prognostic factor in head and neck squamous cell carcinoma. However, significant variance in reported incidence of ENE suggests discordance in perception of ENE among pathologists. This study aims to map the different definitions of histopathological ENE used in the literature. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. Guided by the research question: "How is histopathological ENE defined?" the databases Medline, Embase, and Cochrane were systematically searched. All retrieved studies were reviewed and qualitatively analyzed. Three categories of existing definitions were formed. The systematic literature search yielded 1786 studies after removal of duplicates. Nine hundred and thirty-four full text articles were assessed for inclusion and 44 unique ENE definitions were identified and categorized 1-3; (1) simple definitions only describing a breach in the capsule (48%), (2) definitions also including a description of the perinodal tissue (43%), and (3) definitions adding a description of a specific reaction in the perinodal structure (9%). No consensus definition of ENE exists, but based on the level of details in the identified definitions, three overall categories of ENE definitions were established.

Abstract
OBJECTIVE To determine the prognostic role of extranodal extension (ENE) among patients with human papilloma virus-positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) through a systematic review and meta-analysis of institutional studies. DATA SOURCES MEDLINE, Embase, Scopus, and PubMed. REVIEW METHODS Two independent authors searched the databases on December 3, 2019, to identify studies of HPV+ OPSCC comparing prognostic outcomes stratified by ENE. The I2 statistic was used to determine study heterogeneity. Fixed and random effects models were used to determine hazard ratios (HRs) with 95% CIs. RESULTS Eighteen observational studies met inclusion criteria, yielding 3603 patients with HPV+ OPSCC (1521 ENE+ and 2082 ENE-) with a median follow-up of 49 months. The presence of pathologic ENE (pENE) and radiologic ENE (rENE) was associated with decreased overall survival (pENE HR, 1.89 [95% CI, 1.15-3.13], I2 = 35%; rENE HR, 2.64 [95% CI, 1.46-4.78], I2 = 75%) and distant recurrence (pENE HR, 3.23 [95% CI, 1.25-8.33], I2 = 0%; rENE HR, 3.83 [95% CI, 1.88-7.80], I2 = 0%). Neither pENE nor rENE was associated with locoregional recurrence (pENE HR, 0.75 [95% CI, 0.20-2.84], I2 = 0%; rENE HR, 2.03 [95% CI, 0.86-4.79], I2 = 0%). pENE was not associated with disease-specific survival (pENE HR, 1.45 [95% CI, 0.84-2.49], I2 = 0%). CONCLUSION pENE and rENE are moderately associated with an increased risk of all-cause mortality and recurrence with distant metastasis in a cohort of patients with HPV+ OPSCC. These findings may be used to inform exclusion criteria for deintensification trials and assist in refined risk stratification.

Abstract
Squamous cell carcinomas of the head and neck are the subject of numerous current studies, especially in view of the increasing incidence of tumors induced by human papillomavirus (HPV) and the latest changes to the TNM classification of oropharyngeal squamous cell carcinoma (OPSCC). In addition to HPV status, the presence of extranodal extension of lymph node metastases represents an important risk and prognostic factor, which has now been integrated into the staging algorithm of the eighth edition of TNM classification for HPV-negative OPSCC. In the past numerous studies had shown a lack of prognostic significance of extranodal extension in HPV-associated tumors. However, extranodal extension–as a possible risk factor even in HPV-positive OPSCC–remains an important subject of current studies, which are now particularly characterized by high numbers of cases. In this paper, diagnostic methods and the prognostic significance of extranodal extension in surgically treated HPV-positive OPSCC are presented and discussed based on relevant literature, and the results of current publications are summarized. Further development of diagnostic criteria and procedures as well as international standardization of clinical diagnostics of extranodal extension should be encouraged. Several studies demonstrate that extranodal extension results in worse survival outcomes even in HPV-positive tumors, in contrast to results of previous studies. Consequently, whether the prognostic significance of extranodal extension is not actually relevant to outcome and the staging algorithm of HPV-positive OPSCC should be questioned and further analyzed.

Abstract
BACKGROUND We investigated T cell clonality (TCC) and T cell fraction (TCF) in human papilloma virus associated oropharyngeal squamous cell carcinoma (HPV(+)OPSCC) progressors [cases] vs. non-progressors [controls]. METHODS This nested case-control study included patients undergoing intent-to-cure surgery ± adjuvant therapy from 6/1/2007-10/3/2016. Patients experiencing local/regional/distant disease (progressors), and a consecutive sample of non-progressors were matched (2 controls: 1 case) on tumor subsite, T-stage and number of metastatic lymph nodes. We performed imunosequencing of the CDR3 regions of human TCRβ chains. RESULTS 34 progressors and 65 non-progressors were included. There was no statistically significant difference in baseline TCF (range: 0.039-1.084) and TCC (range: 0.007-0.240) (p > 0.05). Female sex was associated with higher TCF (p = 0.03), while extranodal extension (ENE) was associated with lower TCF (p = 0.01). There was a positive correlation between tumor size and clonality (R = 0.34, p < 0.01). The strongest predictor of progression-free survival (PFS) was TCF (HR 0.80, 95%CI 0.66-0.96, p = 0.02). The strongest predictors of cancer specific survival (CSS) were TCF (HR0.69, 95%CI 0.47-1.00, p < 0.05) and Adult Comorbidity Evaluation-27 (ACE-27) score (p < 0.05). Similarly, the strongest predictors of overall survival (OS) were TCF (HR 0.62, 95%CI 0.43-0.91, p = 0.01) and ACE-27 score (p = 0.03). On multivariable modeling, TCF ≥ 0.4 was independently associated with PFS (HR 0.34, 95%CI 0.14-0.85, p = 0.02) while an ACE-27 score of ≥ 2 independently predicted CSS (HR 3.85, 95%CI 1.07-13.85, p = 0.04) and OS (HR 3.51, 95%CI 1.10-11.20, p = 0.03). CONCLUSIONS In patients with HPV(+)OPSCC, TCF was higher in female patients and those without ENE, suggesting differential immune responses. Lower TCF was significantly and independently associated with disease progression. Better ACE-27 scores appear to predict improved oncologic control.

Int J Oral Maxillofac Surg 2020; 50:309-315. [PMID: 32713777 DOI: 10.1016/j.ijom.2020.07.006] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Revised: 04/18/2020] [Accepted: 07/03/2020] [Indexed: 12/11/2022]
Abstract
A grade of extranodal extension (ENE) may advance risk stratification related to survival in patients with metastatic oral cavity squamous cell carcinoma (OCSCC). Pathological examination of 174 OCSCC patients who were primarily surgically treated with tumour resection and elective neck dissection was performed. Data of ENE presence, its extent (in millimetres), patients and tumour characteristics were statistically analysed with respect to disease-free survival (DFS) and overall survival (OS). Ninety patients (51.7%) were identified with occult nodal disease, with 41 patients (23.6%) presenting with ENE. Receiver operating characteristics (ROC) curve analysis set the threshold at 1.9 mm as an optimal ENE cut-off regarding both DFS and OS. Patients were divided by extent into minor ENE (≤1.9 mm) and major ENE (>1.9 mm) subgroups. The subgroup with minor ENE had significantly higher DFS and OS rates compared with major ENE. ENE cut-off threshold at 1.9 mm discriminates low and high-risk subgroups of patients with occult OCSCC in terms of DFS and OS.

Otolaryngol Head Neck Surg 2020; 163:992-999.

Abstract
OBJECTIVE To determine whether machine learning (ML) can predict the presence of extracapsular extension (ECE) prior to treatment, using common oncologic variables, in patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC). STUDY DESIGN Retrospective database review. SETTING National Cancer Database study. METHODS All patients with HPV-associated OPSCC treated surgically between January 1, 2010, and December 31, 2015, were selected from the National Cancer Database. Patients were excluded if surgical pathology reports did not include information regarding primary tumor stage, number of metastatic regional lymph nodes, size of largest metastatic regional lymph node, and tumor grade. The data were split into a random distribution of 80% for training and 20% for testing with ML methods. RESULTS A total of 3753 adults with surgically treated HPV-associated OPSCC met criteria for inclusion in the study. Approximately 38% of these patients treated with surgical management demonstrated ECE. ML models demonstrated modest accuracy in predicting ECE, with the areas under the receiver operating characteristic curves ranging from 0.58 to 0.68. The conditional inference tree model (0.66) predicted the metastatic lymph node number to be the most important predictor of ECE. CONCLUSION Despite a large cohort and the use of ML algorithms, the power of clinical and oncologic variables to predict ECE in HPV-associated OPSCC remains limited.

Treatment implications of postoperative chemoradiotherapy for squamous cell carcinoma of the oral cavity with minor and major extranodal extension. Oral Oncol 2020; 110:104845. [PMID: 32615441 DOI: 10.1016/j.oraloncology.2020.104845] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 05/20/2020] [Accepted: 06/02/2020] [Indexed: 12/22/2022]
Abstract
OBJECTIVES To evaluate adjuvant chemoradiotherapy (CRT) for patients with oral cavity squamous cell carcinoma (OSCC) with minor or major extranodal extension (ENE). MATERIALS AND METHODS Surgically resected OSCC with pathologically involved lymph node(s) (pN+) between 2006 and 2017. Sections of pN+ were re-reviewed and classified as no, minor (≤2 mm), or major (>2 mm) ENE. Patterns of failure and survival were compared between the groups and stratified by adjuvant treatment. Multivariable (MVA) analysis assessed the value of adjuvant treatment for minor and major ENE. RESULTS Total of 384 patients, 62 had minor and 114 had major ENE. Adjuvant CRT was delivered in 32(15%), 21(34%), and 45(39%) of patients with no, minor and major ENE, respectively. Patients with minor ENE had similar 5-year loco-regional control (LRC) and distant control (DC) but lower disease-free survival (DFS) (38% vs. 51%, p = 0·02) compared to patients with no ENE, while patients with major ENE had marginally lower LRC (59% vs 74%, p = 0·07), lower DC (58% vs 82%,p = 0·005) and DFS (13% vs. 38%, p=·001) compared to those with minor. On MVA, adjuvant chemotherapy was associated with improved DFS for major ENE (adjusted HR = 0·49; 95% CI 0·29-0·85, p = 0·01) but not for minor ENE after adjusting for age, ECOG status, T-, N-category, margin status, and radiotherapy. CONCLUSIONS Adjuvant chemoradiotherapy improves outcomes in patients with major ENE, but the benefit is unclear in patients with minor ENE. Future trials should focus on intensification of treatment for patients with major ENE and alternative adjuvant strategies for patients with minor ENE.
