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.

Extranodal extension of tumour on histopathology is known to be a negative prognostic factor in head and neck cancer. Compelling evidence suggests that extranodal extension detected on radiological imaging is also a negative prognostic factor. Furthermore, if imaging detected extranodal extension could be identified reliably before the start of treatment, it could be used to guide treatment selection, as patients might be better managed with non-surgical approaches to avoid the toxicity and cost of trimodality therapy (surgery, chemotherapy, and radiotherapy together). There are many aspects of imaging detected extranodal extension that remain unresolved or are without consensus, such as the criteria to best diagnose them and the associated terminology. The Head and Neck Cancer International Group conducted a five-round modified Delphi process with a group of 18 international radiology experts, representing 14 national clinical research groups. We generated consensus recommendations on the terminology and diagnostic criteria for imaging detected extranodal extension to harmonise clinical practice and research. These recommendations have been endorsed by 19 national and international organisations, representing 34 countries. We propose a new classification system to aid diagnosis, which was supported by most of the participating experts over existing systems, and which will require validation in the future. Additionally, we have created an online educational resource for grading imaging detected extranodal extensions.

Answer questions and earn CME/CNE The recently released eighth edition of the American Joint Committee on Cancer (AJCC) Staging Manual, Head and Neck Section, introduces significant modifications from the prior seventh edition. This article details several of the most significant modifications, and the rationale for the revisions, to alert the reader to evolution of the field. The most significant update creates a separate staging algorithm for high-risk human papillomavirus-associated cancer of the oropharynx, distinguishing it from oropharyngeal cancer with other causes. Other modifications include: the reorganizing of skin cancer (other than melanoma and Merkel cell carcinoma) from a general chapter for the entire body to a head and neck-specific cutaneous malignancies chapter; division of cancer of the pharynx into 3 separate chapters; changes to the tumor (T) categories for oral cavity, skin, and nasopharynx; and the addition of extranodal cancer extension to lymph node category (N) in all but the viral-related cancers and mucosal melanoma. The Head and Neck Task Force worked with colleagues around the world to derive a staging system that reflects ongoing changes in head and neck oncology; it remains user friendly and consistent with the traditional tumor, lymph node, metastasis (TNM) staging paradigm.

Growing interest is evident in longitudinal mixed methods research, particularly fully longitudinal mixed methods designs in which both quantitative and qualitative data are collected concurrently for the duration of the study. Fully longitudinal mixed methods designs are particularly relevant for research on dynamic phenomena because of their ability to illuminate both quantitative and qualitative dimensions of change in real time as the phenomenon of interest changes. However, these are complex research designs and their data-intense nature makes them potentially burdensome for study participants, challenging for research teams, and costly for funding agencies. Despite growing use, the methodological literature on fully longitudinal mixed methods research is sparse and little guidance is available for researchers considering this approach. We address this gap by describing our experience with the design and implementation of a fully longitudinal mixed methods study of a dynamic phenomenon, namely, family caregiving during cancer treatment. We describe important questions and key decisions confronted while developing the research proposal, proactive strategies for study implementation, and implementation realities encountered while the study was in progress. On the basis of insights gained through real-world experience, we offer three guiding principles for researchers undertaking such a study. First, align the study design with the nature of the dynamics in the phenomenon of interest. Second, plan from the start when and how the integration of the longitudinal quantitative and qualitative data will occur. Third, employ implementation strategies that take into account the practical aspects of repeated contacts with study participants for an extended period.

The staging of oropharyngeal squamous cell carcinoma has undergone key changes in the eighth edition of the American Joint Committee on Cancer Staging Manual, set to take effect January 1, 2018. The most significant change relates to the development of a novel staging system for human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinomas, distinct from that for non-HPV-associated squamous cell carcinomas of the oropharynx. We describe the revised staging parameters and the rationale in support of the changes.

The role of art in medicine is complex, varied and uncertain. To examine one aspect of the relationship between art and medicine, investigators analysed the interactions between a professional artist and five adult patients with head and neck cancer as they cocreated portraits in a clinical setting. The artist and four members of an interdisciplinary team analysed the portraits as well as journal entries, transcripts of portrait sessions and semistructured interviews. Over the course of 5 months, 24 artworks evolved from sittings that allowed both the patients and the artist to collaborate around stories of illness, suffering and recovery. Using narrative inquiry and qualitative arts-based research techniques five emergent themes were identified: embracing uncertainties; developing trusting relationships; engaging in reflective practices; creating shared stories; and empowerment. Similar themes are found in successful physician-patient relationships. This paper will discuss these findings and potential implications for healthcare and medical education.

These NCCN Guidelines Insights focus on recent updates to the 2015 NCCN Guidelines for Head and Neck (H&N) Cancers. These Insights describe the different types of particle therapy that may be used to treat H&N cancers, in contrast to traditional radiation therapy (RT) with photons (x-ray). Research is ongoing regarding the different types of particle therapy, including protons and carbon ions, with the goals of reducing the long-term side effects from RT and improving the therapeutic index. For the 2015 update, the NCCN H&N Cancers Panel agreed to delete recommendations for neutron therapy for salivary gland cancers, because of its limited availability, which has decreased over the past 2 decades; the small number of patients in the United States who currently receive this treatment; and concerns that the toxicity of neutron therapy may offset potential disease control advantages.

These NCCN Guidelines Insights focus on some of the major updates to the 2014 NCCN Guidelines for Thyroid Carcinoma. Kinase inhibitor therapy may be used to treat thyroid carcinoma that is symptomatic and/or progressive and not amenable to treatment with radioactive iodine. Sorafenib may be considered for select patients with metastatic differentiated thyroid carcinoma, whereas vandetanib or cabozantinib may be recommended for select patients with metastatic medullary thyroid carcinoma. Other kinase inhibitors may be considered for select patients with either type of thyroid carcinoma. A new section on "Principles of Kinase Inhibitor Therapy in Advanced Thyroid Cancer" was added to the NCCN Guidelines to assist with using these novel targeted agents.

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Head and Neck Cancers focuses on glottic laryngeal cancer, which is the most common type of laryngeal cancer and has an excellent cure rate. The lymphatic drainage of the glottis is sparse, and early stage primaries rarely spread to regional nodes. Because hoarseness is an early symptom, most glottic laryngeal cancer is early stage at diagnosis. Updates to these guidelines for 2014 include revisions to "Principles of Radiation Therapy" for each site and "Principles of Surgery," and the addition of a new section on "Principles of Dental Evaluation and Management."

BACKGROUND: The present study aims to quantify the opportunity cost of training residents and fellows for head and neck surgery. METHODS: A 2005-2015 review of ablative head and neck surgical procedures was performed using the National Surgical Quality Improvement Program (NSQIP). Work relative value units (wRVU) generated per hour were compared among procedures performed by attendings alone, attendings with residents, and attendings with fellows. RESULTS: Among 34,078 ablative procedures, the rate of wRVU generation per hour was greatest for attendings alone (10.3), followed by attendings with residents (8.9) and attendings with fellows (7.0, p < 0.001). Resident and fellow involvement was associated with opportunity costs of $60.44 per hour (95% CI: $50.21-$70.66/h) and $78.98 per hour ($63.10-$94.87/h, 95% CI), respectively. CONCLUSION: wRVU-based physician reimbursement does not consider or adjust for the extra effort involved in training future head and neck surgeons. LEVEL OF EVIDENCE: NA Laryngoscope, 134:113-119, 2024.

Extranodal extension (ENE) is a pattern of cancer growth from within the lymph node (LN) outward into perinodal tissues, critically defined by disruption and penetration of the tumor through the entire thickness of the LN capsule. The presence of ENE is often associated with an aggressive cancer phenotype in various malignancies including head and neck squamous cell carcinoma (HNSCC). In HNSCC, ENE is associated with increased risk of distant metastasis and lower rates of locoregional control. ENE detected on histopathology (pathologic ENE; pENE) is now incorporated as a risk-stratification factor in human papillomavirus (HPV)-negative HNSCC in the eighth edition of the American Joint Committee on Cancer (AJCC) and the Union for International Cancer Control (UICC) TNM classification. Although ENE was first described almost a century ago, several issues remain unresolved, including lack of consensus on definitions, terminology, and widely accepted assessment criteria and grading systems for both pENE and ENE detected on radiological imaging (imaging-detected ENE; iENE). Moreover, there is conflicting data on the prognostic significance of iENE and pENE, particularly in the context of HPV-associated HNSCC. Herein, we review the existing literature on ENE in HNSCC, highlighting areas of controversy and identifying critical gaps requiring concerted research efforts.
ABSTRACT
Portraits of clinicians quickly became emblematic of what the COVID-19 pandemic has demanded of everyone, especially caregivers who witnessed deaths likely unprecedented in number during their careers. This article describes an arts-based research protocol exploring portraiture as a medium for representing and understanding clinicians' experiences, mostly during the first year of the pandemic. This article presents Shadow of Corona, a large oil on canvas portrait commissioned by the AMA Journal of Ethics to commemorate the American Medical Association's 175th year. The article also includes Sarah, a charcoal study drawing for that portrait, and Front Lines of Care, a 3 by 3 collection of 9 smaller oil on canvas portraits.

BACKGROUND: Few studies have investigated the needs of head and neck surgery trainees and areas for improvement of fellowship programs. METHODS: We conducted a qualitative study by interviewing a nationally representative sample of program directors and national leaders in head and neck surgery. We asked about the current state and strengths of training; and areas for further improvement. All interviews were independently coded and analyzed by two reviewers. RESULTS: All experts (100%) believed that the current training provides a strong foundation and furthermore, a standardized curriculum is beneficial. Multidisciplinary training (80%), participation in tumor boards (75%), and a syllabus (60%) were the most frequently mentioned components. Most believed that a formal certification process would be beneficial (73%), though there was no consensus on the format. CONCLUSION: Experts in head and neck surgery are generally in favor of a standardized curriculum. Further discussions of a formal certification process might be warranted.

BACKGROUND: The recent trends in education and geographic distribution of the head and neck surgery workforce have not been studied extensively. METHODS: We reviewed publicly available sources to locate all fellowship-trained head and neck surgeons and recent graduates. The number of surgeons in each state was compared against head and neck cancer incidence data from the Centers for Disease Control. RESULTS: The number of graduates increased annually by 1 per 100 000 000 people from 2011-2020. The average number of fellowship-trained surgeons per state was 10 (SD: 12). The average number of new head and neck cancer cases per surgeon was 247 (SD: 135). Ten states (20%) had cases >1 SD above the national average/surgeon, while 3 (6%) had cases >1 SD below the national average. CONCLUSION: Head and neck surgeons are located in most states, but not uniformly. Most states have approximately average density of surgeons; however, several states are outliers.
