Genetic Risk For Depression and Quality of Life in Patients With Head and Neck Cancer.

Importance: Although patients with head and neck cancer (HNC) have been shown to experience high distress, few longitudinal studies include a comprehensive evaluation of biopsychosocial factors affecting quality of life (QoL), including genetic risk for depression. Objective: To identify factors at the time of cancer diagnosis associated with QoL scores at 3 months after treatment in patients newly diagnosed with a first occurrence of HNC. Design, Setting, and Participants: This prospective longitudinal study of 1464 participants with a 3-month follow-up, including structured clinical interviews and self-administered measures was carried out at the Department of Otolaryngology Head and Neck Surgery at 2 tertiary care McGill University Affiliated Hospitals, McGill University Health Centre, and Jewish General Hospital. Eligible patients were adults newly diagnosed within 2 weeks with a primary first occurrence of HNC, had a Karnofsky Performance Scale score higher than 60, and an expected survival of more than 6 months. Two hundred and twenty-three patients (72%) consented to participate and completed the baseline questionnaire, and 71% completed the 3-month follow-up measures. Exposures: An a priori conceptual model including sociodemographics, medical variables, psychosocial risk factors, and a polygenic risk score for depression (PRS-D) was tested. Main outcomes and measures: The Functional Assessment of Cancer Therapy-Head and Neck measured QoL at baseline and at 3 months. Results: Participants were mostly men (68.7%), with a mean (range) age of 62.9 (31-92) years, 36.6% having a university degree, 35.6% living alone, and 71.4% diagnosed with advanced HNC with mostly cancers being of the oropharynx (42.2%), oral cavity (17%), and larynx (16.3%). QoL at 3 months after HNC diagnosis was associated with higher PRS-D (B = -4.71; 95% CI, -9.18 to -0.23), and a diagnosis of major depressive disorder within 2 weeks of an HNC diagnosis (B = -32.24; 95% CI, -51.47 to 13.02), lifetime suicidal ideation (B = -22.39; 95% CI, -36.14 to -8.65), living with someone (B = 12.48; 95% CI, 3.43-21.52), having smoked cigarettes in the past 30 days pre-HNC diagnosis (B = -15.50; 95% CI, -26.07 to -4.93), chemotherapy type (B = -11.13; 95% CI, -21.23 to -1.02), and total radiotherapy dose (Gy) (B = -0.008; 95% CI, -0.01 to -0.002). Conclusions and relevance: This study identified the predictive value of a genetic predisposition to depression on QoL and function immediately after oncologic treatments. These findings highlight the potential importance of genetic profiling pretreatment to identify those most susceptible to experience QoL and functional compromise. Depression is a clear area of public health concern and should be a central focus in the treatment of patients with HNC.

Established Adult Tracheostomy Tube Exchange: How Often is Enough?

Currently, there is no clinical consensus on how often adults with long-term tracheostomies should have their tubes exchanged. For high-functioning patients who are able to provide diligent tracheostomy care tubes can be exchanged every 6 months. Patients who have a difficult time with tracheostomy care should have them exchanged every 1-3 months.

Geriatric Voice: Distinctive Clinical Profiles of Working Seniors in a Tertiary Laryngology Clinic.

OBJECTIVES: Voice disorders have been reported in up to 47% of the geriatric population. Few studies have assessed dysphonia in the elderly, with none examining vocal function in working seniors. This study aims to profile the clinical characteristics of individuals aged 65 years and older, comparing working and non-working seniors. STUDY DESIGN: Retrospective cohort study. METHODS: Medical charts were reviewed for patients aged 65 years and older referred to the McGill University Health Centre Laryngology Clinic (January 2018-March 2020). Variables studied included sociodemographics, comorbidities, voice complaints, lifestyle factors, diagnoses, voice acoustics [maximum phonation time (MPT), S/Z ratio, F0], GRBAS scale, Voice Handicap Index-10 (VHI-10), Reflux Symptom Index (RSI), and treatment modalities. RESULTS: A total of 267 patients were included, with a mean [standard deviation (SD)] age of 74.2 (6.6) years and 61% of female patients. Occupation information was available in 148 cases, of which 31.1% were still working and 12.8% were professional voice users. The predominant voice complaint was dysphonia/hoarseness (48.8%) and the most prevalent diagnosis was presbyphonia (31.8%). The mean (SD) VHI-10 and RSI scores were 19.8 (9.0) and 18.7 (9.4) points, respectively. Voice therapy was prescribed for 155 patients (58.7%): 124 attended at least one session with significant post-treatment improvements in the GRBAS and VHI-10 scores (P < 0.01). In the univariate analysis, working seniors had a significantly more prevalent singing habit (P = 0.04) and laryngopharyngeal reflux diagnosis (P = 0.01), displaying a significantly longer MPT (P < 0.001) and lower G-B-S scores (P < 0.05). After adjusting mean differences, only MPT and the G-S scores were significantly different between both groups. CONCLUSIONS: The predominant diagnosis in elders with voice complaints was presbyphonia. Voice therapy proved effective in improving the VHI-10 and GRBAS scores for geriatric patients. Almost one-third of seniors remained in the workforce, demonstrating superior vocal profiles, specifically in the MPT and the grade and strain of perceptual voice quality.

Laryngeal Amyloidosis: What is the Role of Imaging?

OBJECTIVE/HYPOTHESIS: To review the imaging findings of laryngeal amyloidosis and to identify radiological findings suggestive of this disease. STUDY DESIGN: Retrospective case series. METHODS: A retrospective chart review of patients with pathologically confirmed laryngeal amyloidosis was performed from 2009 to 2022. Clinical and demographic factors were collected. A fellowship-trained head and neck radiologist reviewed all computed tomography (CT) scans and magnetic resonance imaging (MRI) findings within this cohort. RESULTS: 12 patients were identified and a total of 36 imaging studies analyzed. Localized amyloidosis was found in the supraglottic region (n = 6), glottic region (n = 7), and subglottic region (n = 5); six patients had disease spanning two subsites. The most common finding on the CT scan was a homogeneous and well-defined submucosal soft tissue mass. Punctate calcifications were present in three cases. The presence of contrast enhancement was identified in the majority of patients who underwent MRI (4/5). MRI showed consistent signal intensity, hypointense, or isointense on both T1-weighted and T2-weighted images. Diffusion-weighted sequences were obtained in every patient and did not demonstrate diffusion restriction. CONCLUSION: This is the largest series searching for unifying imaging characteristics of laryngeal amyloidosis. This research suggests that characteristics from CT and MR provide both similar and unique features of laryngeal amyloidosis on imaging. Both modalities identify a submucosal mass. CT is the preferred modality to demonstrate punctate calcifications, while MRI identifies enhancement and altered signal characteristics. The main benefit of serial imaging is the correlation with patient symptoms, identification of the extent of disease, and assisting in delineating appropriate timing for surgery.

Surgical Treatment of Early Glottic Cancer.

The incidence of all head and neck malignancies is rising worldwide, with carcinoma of the larynx constituting approximately 1% of all cancers. Early glottic cancer responds quite favorably to surgical intervention due to its early presentation, coupled with the low rate of regional and distant metastases. This article focuses on various approaches to the surgical treatment of early glottic cancer. Details include the clinical and radiological evaluation of laryngeal cancer, the goals of treatment, current surgical options for early disease, approach to surgical resection margins and management of nodal disease, and complications associated with each treatment modality.

Genetic predisposition to depression and inflammation impacts symptom burden and survival in patients with head and neck cancer: A longitudinal study.

OBJECTIVE: The primary purpose of this study was to investigate the contribution of genetic predispositions to depression and inflammation, as measured through polygenic risk scores, on symptom burden (physical and psychological) in patients with head and neck cancer in the immediate post-treatment period (i.e., at three months post-diagnosis), as well as on 3-, 6-, 12-, 24- and 36-month survival. METHODS: Prospective longitudinal study of 223 adults (72 % participation) newly diagnosed with a first occurrence of primary head and neck cancer, paired with genetic data (Illumina PsychArray), validated psychometric measures, Structured Clinical Interviews for DSM Disorders (SCID-I), and medical chart reviews. RESULTS: Symptom burden at 3 months was predicted by (R2 adj. = 0.38, p < 0.001): a baseline SCID-I Anxiety Disorder (b = 1.69, B = 0.23, 95%CI = 0.43-2.94; p = 0.009), baseline levels of HADS anxiety (b = 0.20, B = 0.29, 95%CI = 0.07-0.34; p = 0.003), the polygenic risk score (PRS) for depression (b = 0.66, B = 0.18, 95%CI = 0.003-1.32; p = 0.049), and cumulated dose of radiotherapy (b = 0.002, B = 0.46, 95%CI = 0.001-0.003; p < 0.001). When controlling for factors known to be associated with cancer survival, patients with a higher PRS associated with depression and inflammation, respectively, presented higher risk of death within 36 months (b = 1.75, Exp(B) = 5.75, 95%CI = 1.55-21.27, p = 0.009 and b = 0.14, Exp(B) = 1.15, 95%CI = 1.01-1.30, p = 0.03). CONCLUSIONS: Our results outline three potential pathways of symptom burden in patients with head and neck cancer: a genetic predisposition towards depression; an initial anxiety disorder upon being diagnosed with cancer or high levels of anxiety upon diagnosis; and a dose-related response to radiotherapy. One may want to investigate early interventions in these areas to alleviate symptom burden in patients faced with a life-threatening disease, as well as consider targeting genetic predisposition towards depression and inflammation implicated in survival. The high prevalence of distress in patients with head and neck cancer is an opportunity to study genetic predispositions, which could potentially be broadly generalized to other cancers and diseases.

Airway Resistance and Respiratory Distress in Laryngeal Cancer: A Computational Fluid Dynamics Study.

BACKGROUND: Obstructive upper airway pathologies are a great clinical challenge for the airway surgeon. Protection against acute obstruction is critical, but avoidance of unnecessary tracheostomy must also be considered. Decision-making regarding airway, although supported by some objective findings, is largely guided by subjective experience and training. This investigation aims to study the relationship between clinical respiratory distress and objective measures of airway resistance in laryngeal cancer as determined by computational fluid dynamic (CFD) and morphometric analysis. METHODS: Retrospective CT and clinical data were obtained for series of 20 cases, defined as newly diagnosed laryngeal cancer patients who required admission or urgent airway surgery, and 20 controls. Cases and controls were matched based on T-staging. Image segmentation and morphometric analysis were first performed. Computational models based on the lattice Boltzmann method were then created and used to quantify the continuous mass flow, rigid wall, and constant static pressure inlet boundary conditions. RESULTS: The analysis demonstrated a significant relationship between airway resistance and acute obstruction (OR 1.018, 95% CI 1.001-1.045). Morphometric analysis similarly demonstrated a significant relationship when relating measurements based on the minimum cross-section, but not on length of stenosis. Morphometric measurements also showed significance in predicting CFD results, and their relationship demonstrated that airway pressures increase exponentially below 2.5 mm. Tumor subsite did not show a significant difference, although the glottic subgroup tended to have higher resistances. CONCLUSION: Airway resistance analysis from CFD computation correlated with presence of acute distress requiring emergent management. Morphometric analysis showed a similar correlation, demonstrating a radiologic airway assessment technique on which future risk estimation could be performed.

Complication Rate of Percutaneous Dilatational Tracheostomy in Critically Ill Adults With Obesity: A Systematic Review and Meta-analysis.

Importance: Obesity has traditionally been described as a relative contraindication to percutaneous dilatational tracheostomy (PDT). Increased familiarity with the technique and use of bronchoscopy or real-time ultrasonography to enhance visualization have led many practitioners to expand the indication for PDT to patients historically deemed to have high risk of perioperative complications. Objective: To assess the reported complication rate of PDT in critically ill adults with obesity and compare it with that of open surgical tracheostomies (OSTs) in this patient population and with that of PDT in their counterparts without obesity. Data Sources: In this systematic review and meta-analysis, Ovid MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from January 1, 2000, to March 1, 2022. Key terms related to percutaneous tracheostomy and obesity were included. Study Selection: Original investigations of critically ill adult patients (age ≥18 years) with obesity who underwent PDT that reported at least 1 complication of interest were included. Case reports or series with fewer than 5 patients were excluded, as were studies in a language other than English or French. Data Extraction and Synthesis: Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) were used, with independent extraction by multiple observers. Frequencies were reported for all dichotomous variables. Relative risks for complications were calculated using both fixed-effects and random-effects models in the meta-analysis. Main Outcomes and Measures: Main outcomes included mortality directly associated with the procedure, conversion to OST, and complications associated with the procedure (subclassified into life-threatening or non-life-threatening adverse events). Results: Eighteen studies were included in the systematic review, comprising 1355 patients with obesity who underwent PDT. The PDT-related complication rate was 16.6% among patients with obesity overall (791 patients, 17 studies), most of which were non-life-threatening. Only 0.6% of cases (8 of 1314 patients, 17 studies) were aborted or converted to an OST. A meta-analysis of 12 studies (N = 4212; 1078 with obesity and 3134 without obesity) showed that patients with obesity had a higher rate of complications associated with PDT compared with their counterparts without obesity (risk ratio, 1.78; 95% CI, 1.38-2.28). A single study compared PDT with OST directly for critically ill adults with obesity; thus, the intended meta-analysis could not be performed in this subgroup. Conclusions and Relevance: The findings suggest that the rate of complications of PDT is low in critically ill individuals with obesity, although the risk of complications may be higher than in individuals without obesity.

Percutaneous Tracheostomy With a Demistifier Canopy in the COVID-19 Era: A Safe Technique in the Intensive Care Unit.

BACKGROUND: Endoscopic percutaneous tracheostomy (PT) is a safe technique that is performed frequently by otolaryngologists and intensivists. New challenges have been identified in order to maintain the safety of this procedure during the COVID-19 pandemic. A novel approach, using a modified demistifier canopy, was developed during the first wave of the pandemic and implemented for 17 consecutive percutaneous tracheostomies in order to enhance procedural safety. METHODS: A protocol was developed after performing a literature review of tracheostomy in COVID-19 patients. A multidisciplinary tracheostomy team was established, including the departments of otolaryngology, critical care, and respiratory therapy. Simulation was performed prior to each PT, and postoperative debriefings were done. RESULTS: A protocol and technical description of PT using a modified demistifier canopy covering was written and video documented. Data were collected on 17 patients who underwent this procedure safely in our tertiary care hospital. There were no procedure-related complications, and no evidence of COVID-19 transmission to any member of the health care team during the study period. CONCLUSION: As patients continue to recover from COVID-19, their need for tracheostomy will increase. The technique described provides a safe, multidisciplinary method of performing PT in COVID-19 patients.

Functional Analysis of Injectable Substance Treatment on Surgically Injured Rabbit Vocal Folds.

OBJECTIVES: The objective of this study was to evaluate the efficacy of immediate injection treatments of dexamethasone, hyaluronic acid (HA)/gelatin (Ge) hydrogel and glycol-chitosan solution on the phonatory function of rabbit larynges at 42 days after surgical injury of the vocal folds, piloting a novel ex vivo phonatory functional analysis protocol. METHODS: A modified microflap procedure was performed on the left vocal fold of 12 rabbits to induce an acute injury. Animals were randomized into one of four treatment groups with 0.1 mL injections of dexamethasone, HA/Ge hydrogel, glycol-chitosan or saline as control. The left mid vocal fold lamina propria was injected immediately following injury. The right vocal fold served as an uninjured control. Larynges were harvested at Day 42 after injection, then were subjected to airflow-bench evaluation. Acoustic, aerodynamic and laryngeal high-speed videoendoscopy (HSV) analyses were performed. HSV segments of the vibrating vocal folds were rated by three expert laryngologists. Six parameters related to vocal fold vibratory characteristics were evaluated on a Likert scale. RESULTS: The fundamental frequency, one possible surrogate of vocal fold stiffness and scarring, was lower in the dexamethasone and HA/Ge hydrogel treatment groups compared to that of the saline control (411.52±11.63 Hz). The lowest fundamental frequency value was observed in the dexamethasone group (348.79±14.99 Hz). Expert visual ratings of the HSV segments indicated an overall positive outcome in the dexamethasone treatment group, though the impacts were below statistical significance. CONCLUSION: Dexamethasone injections might be used as an adjunctive option for iatrogenic vocal fold scarring. An increased sample size, histological correlate, and experimental method improvements will be needed to confirm this finding. Results suggested a promising use of HSV and acoustic analysis techniques to identify and monitor post-surgical vocal fold repair and scarring, providing a useful tool for future studies of vocal fold scar treatments.

Biopsychosocial Markers of Body Image Concerns in Patients with Head and Neck Cancer: A Prospective Longitudinal Study.

(1) Background: Patients and survivors of head and neck cancer (HNC) are at a high risk of developing body image concerns. Despite the prevalence of body image concerns in patients with HNC, there is a lack of longitudinal research exploring the wide array of its associated determinants. The current longitudinal study examined the determinants and longitudinal course of body image dissatisfaction in patients with HNC. (2) Methods: Patients participated in Structured Clinical Interviews and self-administered questionnaires at four time-points: (T1) upon cancer diagnosis, (T2) at 3 months post-diagnosis, (T3) at 6 months post-diagnosis, and (T4) at 12 months post-diagnosis. They also underwent a disfigurement rating on an objective scale. (3) Results: Two hundred and twenty-four patients participated in our study. Fourteen percent to twenty-eight percent of patients reported at least moderate body image concerns across time points, with the lowest rates at baseline and the highest at 3 months (T1). It was found that patients more predisposed to developing higher levels of body image concerns presented physical markers (i.e., advanced cancer stage, lower physical functioning, higher disfigurement), psychosocial markers (i.e., higher depression, higher anxiety, and higher levels of coping with denial), and health disparities (i.e., younger age, female sex, French language, and marital status, with divorced and widowers most affected). (4) Conclusions: The findings of this study highlight the multifaceted nature of body image concerns in patients with HNC and its biopsychosocial determinants. Clinicians should pay specific attention to these biopsychosocial markers in their clinics to predict high levels of body image concerns and tailor communication/refer for support accordingly.

Diagnostic Accuracy of Liquid Biomarkers in Airway Diseases: Toward Point-of-Care Applications.

Background: Liquid biomarkers have shown increasing utility in the clinical management of airway diseases. Salivary and blood samples are particularly amenable to point-of-care (POC) testing due to simple specimen collection and processing. However, very few POC tests have successfully progressed to clinical application due to the uncertainty and unpredictability surrounding their diagnostic accuracy. Objective: To review liquid biomarkers of airway diseases with well-established diagnostic accuracies and discuss their prospects for future POC applications. Methodology: A literature review of publications indexed in Medline or Embase was performed to evaluate the diagnostic accuracy of liquid biomarkers for chronic obstructive pulmonary disease (COPD), asthma, laryngopharyngeal reflux (LPR), and COVID-19. Results: Of 3,628 studies, 71 fulfilled the inclusion criteria. Sputum and blood eosinophils were the most frequently investigated biomarkers for the management of asthma and COPD. Salivary pepsin was the only biomarker with a well-documented accuracy for the diagnosis of LPR. Inflammatory blood biomarkers (e.g., CRP, D-dimers, ferritin) were found to be useful to predict the severity, complications, and mortality related to COVID-19 infection. Conclusion: Multiple liquid biomarkers have well-established diagnostic accuracies and are thus amenable to POC testing in clinical settings.

Body Image Concerns in Patients With Head and Neck Cancer: A Longitudinal Study.

Objective: Head and neck cancer (HNC) treatments are known to significantly affect functionality and appearance, leading to an increased risk for body image disturbances. Yet, few longitudinal studies exist to examine body image in these patients. Based on a conceptual model, the current study aimed to determine, in patients newly diagnosed with HNC: (1) the prevalence, level, and course of body image concerns; (2) correlates of upon cancer diagnosis (pre-treatment) body image concerns; (3) predictors of immediate post-treatment body image concerns; and (4) association between body image concerns and levels of anxiety, depression, suicidal ideation, support (i.e., satisfaction with support from physician, social/family wellbeing, and unmet support needs), and alcohol and drug misuse. Methods: Two hundred and twenty-three (participation rate = 72%), newly diagnosed with a primary HNC were assessed using structured clinical interviews and psychometric measures at three, and 6 months after diagnosis. Primary outcome was 3-month, as it was most salient to body image disturbance. Multiple linear regression analyses were conducted on the potential body image predictors, based on the model. Results: Sixty-eight percent of patients with HNC (n = 148 of 218) presented some level of body image concerns. Body image concerns at baseline (i.e., upon cancer diagnosis, pre-treatment) and post-treatment were significantly related and significantly increased from pre- to post-treatment. Immediately post-treatment (i.e., at 3 month follow-up), 89% (n = 132 of 148) presented some level of body image concerns. Correlates of body image concerns in patients with HNC at baseline included: physical symptom burden, difficulties with communication and eating, coping with the cancer diagnosis using denial, suicidal ideation, and having had a past anxiety diagnosis. When controlling for sociodemographic and medical variables, body image concerns in patients with HNC in the immediate post-treatment were predicted by: baseline body image, physical symptom burden, and neuroticism. Conclusion: This longitudinal study helps identify patients more susceptible to experience body image disturbance following head and neck cancer. Clinicians ought to pay special attention to body image concerns upon cancer diagnosis, physical symptom burden, and neuroticism, and may want to target these factors in future preventive interventions.

Psychosocial outcomes of human papillomavirus (HPV)- and non-HPV-related head and neck cancers: A longitudinal study.

OBJECTIVES: Human papillomavirus (HPV) has prompted a need to further investigate how this new biomarker changes the head and neck cancer (HNC) psychosocial landscape. This study aimed to: (a) characterize the sociodemographic, psychological, and social profiles of patients with HPV-positive versus -negative squamous cell carcinoma of the head and neck; and (b) identify how HPV status contributes to anxiety and depression (primary outcome), quality of life (QoL), and sexuality needs. METHODS: We conducted a prospective longitudinal study of 146 patients newly diagnosed with oral, oropharyngeal, nasopharyngeal, and hypopharyngeal cancer. Seventy-nine patients were HPV-positive and 67 HPV-negative. Patients completed self-administered psychometric measures upon HNC and 3-month follow-up, and Structured Clinical Interviews for DSM Diagnoses. RESULTS: Patients with HPV-negative tumors generally presented with higher anxiety and depression and lower QoL immediately post-HNC diagnosis (<2 weeks) compared to HPV-positive cancers. A Major Depressive Disorder (MDD) immediately post-HNC diagnosis negatively affected patients' anxiety and depression and QoL levels upon diagnosis only when the cancer was HPV-positive. Immediately posttreatment, HPV status was not associated with outcomes. A previous history of suicidal ideation, and upon cancer diagnosis cigarette smoking, anxiety and depression, and feeling close to one's partner were instead explanatory. CONCLUSION: While patients with HPV-positive HNC generally present with initially lower psychological distress, their vulnerability immediately posttreatment indicates an equal need for support. Head and neck clinics may need to better address MDD, anxiety and depression, a prior history of suicidal ideation, health behavior change, and quality of relationships.

Metastatic Clear Renal-Cell Carcinoma Mimicking Anaplastic Thyroid Cancer: A Case Report.

Metastatic renal cell carcinoma to the thyroid is a rare yet aggressive histopathologic diagnosis, which may often be omitted from the initial clinical differential. This is in part due to the long latency period between the initial renal primary and appearance of metastatic disease, coupled with the diagnostic limitations of fine-needle aspiration biopsies. We herein present an interesting case of a metastatic clear-cell renal-cell carcinoma mimicking an aggressive primary thyroid neoplasm, 10 years after a nephrectomy for a renal primary, highlighting key diagnostic and management considerations.

Longitudinal study indicating antecedent psychosocial vulnerability as predictor of anxiety disorders post-treatment in people with head and neck cancer.

OBJECTIVE: This study aimed to: (1) determine the contribution of pre-cancer psychosocial vulnerability as an independent predictor of anxiety disorder (AD) onset immediately post-treatment in patients diagnosed with a first occurrence of head and neck cancer (HNC), controlling for sociodemographics and medical variables; and (2) estimate prevalence of AD and identify trajectories from the moment of diagnosis to the immediate post-treatment (i.e., over a period of 3 months) in this population. METHODS: Two-hundred twenty-four consecutive patients (participation rate = 72%) newly diagnosed with a primary HNC were assessed with a structured clinical interview for a mental disorder, validated psychometric measures, and medical chart reviews. RESULTS: Twenty-five percent of patients presented a lifetime AD, 19.4% within 2 weeks of HNC diagnosis, and 16.6% immediately post-treatment; representing 26.7% of patients with AD at any timepoint from the moment of diagnosis to immediately post-treatment. Patients were more likely to present an AD immediately post-treatment when they: were diagnosed with advanced-stage cancer (OR = 3.40, p = 0.006), presented a upon cancer diagnosis AD (OR = 2.45, p = 0.008) and/or experienced childhood abuse (OR = 1.96, p = 0.03). CONCLUSIONS: Several AD trajectories may arise when patients are diagnosed with primary HNC. Health professionals should address AD and screen for risk factors (i.e., advanced stage cancer, AD upon cancer diagnosis, history of childhood abuse) as early as possible to assure optimal mental health care in this vulnerable population.
