Article Synopsis
  • A study evaluated a new curriculum designed to boost confidence among nonpsychiatry healthcare providers in treating mental health issues.
  • Nonbehavioral health physicians and practitioners participated in a 2-day seminar, with pre- and posttests measuring their confidence in managing mental health conditions and medications.
  • Results showed significant improvements in confidence, with 87.5% of participants rating the seminar as "excellent" and an increase in those treating depression and anxiety post-seminar, suggesting this approach can effectively expand the mental health workforce.

Article Synopsis
  • Accurate staging for nasopharyngeal carcinoma (NPC) is vital for treatment and prognosis, using the AJCC/UICC TNM system as a standardized approach, necessitating ongoing updates to reflect modern care practices.
  • The study aimed to enhance the accuracy and relevance of the TNM-8 system for NPC by analyzing patient data from 2014-2015 and undergoing rigorous validation processes leading to the development of TNM-9.
  • Results from over 4,900 patients highlighted that advanced extranodal extension was a key negative prognostic factor, prompting a proposed restructuring of staging for nonmetastatic cases from TNM-8 classifications.

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).

Article Synopsis
  • Detection of extranodal extension (ENE) in head and neck squamous cell carcinoma indicates a poor prognosis, but there's currently a lack of standardized diagnostic criteria and reporting methods in the literature.
  • The Head and Neck Cancer International Group organized a modified Delphi process involving 19 pathology experts to establish consensus recommendations for diagnosing and reporting ENE.
  • The resulting guidelines, supported by 19 organizations from 34 countries, aim to standardize the diagnosis and improve accuracy in data collection regarding histology detected extranodal extension.

Importance: Despite interest in therapy de-escalation for survivors of human papillomavirus-mediated oropharyngeal squamous cell carcinoma (HPV-positive OPSCC), the association of de-escalated therapy with patient-reported quality of life (QoL) outcomes and burden of depressive symptoms remains unclear.

Objective: To identify associations between clinicopathologic and therapeutic variables with patient-reported QoL outcomes and depression symptom burden in patients with HPV-positive OPSCC, who were enrolled in a therapy de-escalation trial.

Design, Setting, And Participants: In this nonrandomized controlled, open-label, curative-intent therapy de-escalation clinical trial in adults with stage I, II, and III HPV-positive OPSCC, patients were recruited from a high-volume head and neck oncology practice.

The objective of the study is to compare sentinel lymph node (SLN) identification rates and performance characteristics of lymphoscintigraphy using Tc-sulfur colloid (SC) and Tc-tilmanocept (TL) for head and neck cutaneous melanoma. This study is a retrospective study, conducted at a single, tertiary care cancer center. Patients underwent sentinel lymph node biopsy (SLNB) for head and neck cutaneous melanoma, using SC or TL, between October 2014 and February 2019.

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.

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.

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.

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.

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 , a large oil on canvas portrait commissioned by the to commemorate the American Medical Association's 175th year.

Objective: To study the association between the development of moderate or greater depression during curative-intent therapy and overall survival (OS) in patients with stages II-IV head and neck cancer (HNC).

Methods: In this secondary analysis of a randomized double-blind placebo-controlled trial, of 148 eligible participants diagnosed with stages II-IV HNC but without baseline depression, 125 were evaluable and were randomly allocated to prophylactic escitalopram oxalate (n = 60) or placebo (n = 65). Participants were followed for development of moderate or greater depression, using Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR, range 0-27, score ≥11 indicated moderate or greater depression), and were stratified by demographics; cancer site and stage; and primary treatment modality (surgery with or without radiotherapy vs.

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.

Background And Purpose: To explore the prognostic value of different radiologic extranodal extension (rENE) grades and their potential improvement for the 8th edition N category in nasopharyngeal carcinoma (NPC).

Materials And Methods: From 2009 to 2013, a cohort of 1887 patients with NPC was retrospectively enrolled and randomized to the training (n = 955) and validation (n = 932) groups. rENE was categorized as follows: grade 0, nodes without rENE; grade 1, nodes with rENE infiltrating the surrounding fat only; grade 2, matted nodes; grade 3, nodes with rENE infiltrating adjacent structures.

Medical and especially surgical teaching stresses the importance of careful observation, developing tolerance for ambiguity, and cultivating empathy for patients' and colleagues' experiences of receiving and giving health care. Portraiture is defined by portraitist Mark Gilbert as a collaborative process between subject and artist; sitting is as critical to this process as painting or drawing. This article draws upon the second author's work with Gilbert to examine how portraiture can motivate key teaching and learning goals in health professions education by facilitating learners' explorations of their own and others' biases, limitations, and approaches to gathering information from and about a source (eg, a subject or a patient).
