Interventions for Concerning Patient-Reported Outcomes in Routine Cancer Care: A Systematic Review.

IMPORTANCE: Collecting patient-reported outcomes (PROs) in routine cancer care improves patient-clinician communication, decision making, and overall patient satisfaction. Recommendations exist regarding standardized ways to collect, store, and interpret PRO data. However, evidence on incorporating PROs into cancer process of care, especially the type of HIs that are warranted after observing a concerning PRO and the effectiveness of these HIs are lacking. OBJECTIVE: This study summarizes HIs triggered after PRO completion and their effectiveness in improving patient outcomes for adults being treated for cancer types that are resource intensive and associated with high symptom burden [i.e., gastrointestinal (GI), lung, and head and neck cancer (HNC)]. Secondary outcomes included factors associated with poor implementation of PROs. EVIDENCE REVIEW: A literature search of peer-reviewed publications on MEDLINE, CINAHL Plus, APA PsycInfo, Scopus, and Cochrane was conducted following PRISMA guidelines from 1 January 2012, to 31 July 2022. Trial and real-world studies describing HIs after PRO completion for adult patients being treated for GI, lung, and HNC were included. Sixteen studies involving 144,496 patients were included. The Joanna Briggs Institute critical appraisal checklist was used to assess risk of bias. FINDINGS: Of the 16 included studies, 5 included patients with HNC. Commonly used PRO measurement tools were the PRO-CTCAE and ESAS. Only three studies reported specific HIs delivered in response to concerning PROs and measured their effectiveness on patient outcomes. In all three studies, these HIs significantly improved cancer-related care. The most common HIs undertaken in response to concerning PROs were referrals to other specialists/allied healthcare professionals, medication changes, or self-management advice. Provider-related barriers to PRO measurement and delivery included the overwhelming number of alerts, the time required to address each PRO and the unclear role of healthcare providers in response to these alerts. Patient-related barriers included lower digital literacy and socioeconomic status, older age, rural living, and patients suffering from GI and HNC. CONCLUSIONS AND RELEVANCE: This review highlights that PRO-triggered HIs are heterogenous and can improve patient quality of life. Further studies are necessary to determine the types of interventions with the greatest impact on patient care and outcomes.

A scoping assessment of dental services at designated head and neck cancer centres in Ontario, Canada.

BACKGROUND: Dentists serve a crucial role in managing treatment complications for patients with head and neck cancer, including post-radiation caries and oral infection. To date, dental services for head and neck cancer patients in Ontario, Canada have not been well characterized and considerable disparities in allocation, availability, and funding are thought to exist. The current study aims to describe and assess the provision of dental services for head and neck cancer patients in Ontario. METHODS: A mixed methods scoping assessment was conducted. A purposive sample of dentist-in-chiefs at each of Ontario's 9 designated head and neck cancer centres (tertiary centres which meet provincially-set quality and safety standards) was invited to participate. Participants completed a 36-item online survey and 60-minute semi-structured interview which explored perceptions of dental services for head and neck cancer patients at their respective centres, including strengths, gaps, and inequities. If a centre did not have a dentist-in-chief, an alternative stakeholder who was knowledgeable on that centre's dental services participated instead. Thematic analysis of the interview data was completed using a mixed deductive-inductive approach. RESULTS: Survey questionnaires were completed at 7 of 9 designated centres. A publicly funded dental clinic was present at 5 centres, but only 2 centres provided automatic dental assessment for all patients. Survey data from 2 centres were not captured due to these centres' lack of active dental services. Qualitative interviews were conducted at 9 of 9 designated centres and elicited 3 themes: (1) lack of financial resources; (2) heterogeneity in dentistry care provision; and (3) gaps in the continuity of care. Participants noted concerning under-resourcing and limitations/restrictions in funding for dental services across Ontario, resulting in worse health outcomes for vulnerable patients. Extensive advocacy efforts by champions of dental services who have sought to mitigate current disparities in dentistry care were also described. CONCLUSIONS: Inequities exist in the provision of dental services for head and neck cancer patients in Ontario. Data from the current study will broaden the foundation for evidence-based decision-making on the allocation and funding of dental services by government health care agencies.

Access to symptom screening and severe symptom risk among cancer patients with major mental illness.

INTRODUCTION: Cancer symptom screening has the potential to improve cancer outcomes, including reducing symptom burden among patients with major mental illness (MMI). We determined rates of symptom screening with the Edmonton Symptom Assessment System (ESAS-r) and risk of severe symptoms in cancer patients with MMI. METHODS: This retrospective cohort study used linked administrative health databases of adults diagnosed with cancer between 2007 and 2020. An MMI was measured in the 5 years prior to cancer diagnosis and categorized as inpatient, outpatient, or no MMI. Outcomes were defined as time to first ESAS-r screening and time to first moderate-to-severe symptom score. Cause-specific and Fine and Gray competing events models were used for both outcomes, controlling for age, sex, rural residence, year of diagnosis and cancer site. RESULTS: Of 389,870 cancer patients, 4049 (1.0%) had an inpatient MMI and 9775 (2.5%) had an outpatient MMI. Individuals with inpatient MMI were least likely to complete an ESAS-r (67.5%) compared to those with outpatient MMI (72.3%) and without MMI (74.8%). Compared to those without MMI, individuals with an inpatient or outpatient MMI had a lower incidence of symptom screening records after accounting for the competing risk of death (subdistribution Hazard Ratio 0.77 (95% CI 0.74-0.80) and 0.88 (95% CI 0.86-0.90) respectively). Individuals with inpatient and outpatient MMI status consistently had a significantly higher risk of reporting high symptom scores across all symptoms. CONCLUSIONS: Understanding the disparity in ESAS-r screening and management for cancer patients with MMI is a vital step toward providing equitable cancer care.

Comparing the piezoelectric and conventional osteotome in rhinoplasty.

IMPORTANCE: Edema affects outcomes in Rhinoplasty. Edema and bruising influences patient satisfaction in the perioperative period. OBJECTIVE: A qualitative analysis of edema comparing piezoelectric and conventional osteotome, and a qualitative comparison of bruising between these methods. DESIGN: A prospective cohort study of 31 aesthetic Rhinoplasty cases. Participants act as their own control measure. An osteotome is used on one side of the nasal bone and a piezoelectric is used contralaterally. MAIN OUTCOMES AND MEASURES: Edema is calculated by comparing a pre and post-operative 3-D image with volumetric analysis. Ecchymosis is scored and compared. RESULTS: The mean volume of the piezoelectric was 1.37 cc (SD 0.87) and the mean volume of the osteotome was 1.17 cc (SD 0.70) (0.19 absolute difference [95 % CI 0.3 to 0.35], p = 0.02). Bruising scores were 0.35 points lower for the piezoelectric arm (-0.35 absolute difference [95%CI -0.7 to 0.06], p < 0.01). This corresponded to 26 % of lateral piezo osteotomies having significant bruising compared to 38 % of the lateral osteotomies using the conventional technique. CONCLUSION: There is a difference in postoperative edema and bruising with the piezoelectric and conventional osteotome for lateral osteoetomy in Rhinoplasty. There is more edema with the piezoelectric and more ecchymosis with the conventional osteotome.

Surgical Case Volume has an Impact on Outcomes for Patients with Lateral Neck Disease in Thyroid Cancer.

BACKGROUND: This study aimed to assess whether surgical case volume for lateral neck dissection has an impact on the survival of patients who have well-differentiated thyroid cancer (WDTC) with lateral cervical node metastases. The authors used a population-based cohort study design. METHODS: The study cohort consisted of WDTC patients in Ontario Canada who underwent thyroidectomy and lateral neck dissection. These patients were identified using both hospital- and surgeon-level administrative data between 1993 and 2017 (n = 1832). Surgeon and hospital volumes were calculated based on the number of cases managed in the year before the procedure by the physician and at the institution managing each case, respectively, and divided into tertiles. Multilevel Cox regression models were used to estimate the effect of volume on disease-free survival (DFS). RESULTS: A crude model without patient or treatment characteristics demonstrated that DFS was associated with both higher surgeon volume tertiles (p < 0.01) and higher hospital volume tertiles (p < 0.01). After control for clustering, patient/treatment covariates, and hospital volume, the lowest surgeon volume tertile (range, 0-20/year; mean, 6.5/year) remained an independent statistically significant negative predictor of DFS (hazard ratio, 1.71; 95 % confidence interval, 1.22-2.4; p < 0.01). CONCLUSION: Surgeon lateral neck dissection case volume is a predictor of better DFS for thyroid cancer patients, with the lowest surgeon volume tertile (<20 neck dissections per year) demonstrating poorer DFS.

Incident Cancer Detection During the COVID-19 Pandemic.

BACKGROUND: Resource restrictions were established in many jurisdictions to maintain health system capacity during the COVID-19 pandemic. Disrupted healthcare access likely impacted early cancer detection. The objective of this study was to assess the impact of the pandemic on weekly reported cancer incidence. PATIENTS AND METHODS: This was a population-based study involving individuals diagnosed with cancer from September 25, 2016, to September 26, 2020, in Ontario, Canada. Weekly cancer incidence counts were examined using segmented negative binomial regression models. The weekly estimated backlog during the pandemic was calculated by subtracting the observed volume from the projected/expected volume in that week. RESULTS: The cohort consisted of 358,487 adult patients with cancer. At the start of the pandemic, there was an immediate 34.3% decline in the estimated mean cancer incidence volume (relative rate, 0.66; 95% CI, 0.57-0.75), followed by a 1% increase in cancer incidence volume in each subsequent week (relative rate, 1.009; 95% CI, 1.001-1.017). Similar trends were found for both screening and nonscreening cancers. The largest immediate declines were seen for melanoma and cervical, endocrinologic, and prostate cancers. For hepatobiliary and lung cancers, there continued to be a weekly decline in incidence during the COVID-19 period. Between March 15 and September 26, 2020, 12,601 fewer individuals were diagnosed with cancer, with an estimated weekly backlog of 450. CONCLUSIONS: We estimate that there is a large volume of undetected cancer cases related to the COVID-19 pandemic. Incidence rates have not yet returned to prepandemic levels.

Active Versus Passive Transcutaneous Bone Conduction Hearing Devices: A Systematic Review and Meta-Analysis.

OBJECTIVES: Active and passive transcutaneous devices (tBCHDs) have been introduced in an effort to address complication concerns with percutaneous devices. Direct comparison of active and passive devices through evidence synthesis practices is incomplete. This systematic review and meta-analysis sought to synthesize and compare available evidence on audiological, quality of life, and complication-related outcomes of active and passive tBCHDs. DESIGN: MEDLINE, EMBASE, CINAHL, and Cochrane CENTRAL were searched from inception to September 23, 2019. Observational and experimental studies investigating active or passive tBCHDs in adults were eligible. Studies were screened independently in duplicate. This study is reported in accordance with the PRISMA guidelines. Risk of bias and quality assessments were completed using the Newcastle-Ottawa Scale and the Quality Appraisal Tool for Case Series. Meta-analysis was performed with random-effects models. Audiological outcomes included changes in pure-tone average, functional hearing, and high-frequency hearing. Quality of life outcomes included patient-reported results. Complications included minor, major, and total complications experienced. RESULTS: One thousand five hundred forty-two nonduplicate articles were screened. Twenty-eight studies were included. Quality of included studies was low overall. The pooled complication rate for active devices was 14.8% (95% confidence interval: 0.09-0.21, I2: 0%). The pooled improvement in functional hearing for active devices among those with mixed or conductive hearing loss was 31.8 dB (95% confidence interval: 27.7-35.9, I2: 44.6). Improvement in functional hearing ranged from 25.2 to 44.3 dB for passive devices. Active devices provided improved high-frequency hearing compared to passive devices: the weighted average hearing gains at 2, 3, 4, and 6 kHz were 26.5, 25.7, 31.8, and 34.3 dB for active devices and 26.2, 21.1, 16.8, and 6.4 dB for passive devices, respectively. Both device types demonstrated improvement in ease of communication, reverberation, and understandability in background noise. CONCLUSIONS: Both active and passive tBCHDs demonstrate acceptable safety profiles and QoL improvements. Active devices may provide better hearing outcomes, especially in high frequencies, but high-quality comparative studies are lacking. Future work is needed in this regard.

Surgeons disciplined by regulatory bodies in Canada between 2000 and 2017.

Identifying characteristics of disciplined surgeons is important for public safety. A database of all physicians disciplined by a Canadian provincial medical regulatory authority (College of Physicians and Surgeons) between 2000 and 2017 was constructed, and comparisons between surgeons and other physicians were undertaken. Of 1100 disciplined physicians, 174 (15.8 %) were surgeons. Obstetrics and gynecology was the specialty with the most disciplined surgeons (57 of 174 [32.8%]), followed by general surgery (48 of 174 [27.6%]). The overall disciplinary rate for surgeons was higher than for other physicians (12.59, 95 % confidence interval [CI] 10.69-14.83 v. 9.85, 95 % CI 8.88-10.94 cases per 10 000 physician-years, p = 0.013). Even after adjusting for surgeon age, sex, international medical graduation and years in practice, surgeons remained more likely than other physicians to be disciplined for standard of care issues (55.6%, 95% CI 46.6-64.2 v. 38.7%, 95% CI 32.6-45.2, p < 0.001).

Elective neck dissection versus positron emission tomography-computed tomography-guided management of the neck in clinically node-negative early oral cavity cancer: A cost-utility analysis.

BACKGROUND: In early oral cavity cancer, elective neck dissection (END) for the clinically node-negative (cN0) neck improves survival compared with observation. This paradigm has been challenged recently by the use of positron emission tomography-computed tomography (PET-CT) imaging in the cN0 neck. To inform this debate, we performed an economic evaluation comparing PET-CT-guided therapy with routine END in the cN0 neck. METHODS: Patients with T1-2N0 lateralized oral tongue cancer were analyzed. A Markov model over a 40-year time horizon simulated treatment, disease recurrence, and survival from a US health care payer perspective. Model parameters were derived from a review of the literature. RESULTS: The END strategy was dominant, with a cost savings of $1576.30 USD, an increase of 0.055 quality-adjusted life years (QALYs), a net monetary benefit of $4303 USD, and a 0.22 life-year advantage. END was sensitive to variation in cost and utilities in deterministic and probabilistic sensitivity analyses. PET-CT became the preferred strategy when decreasing occult nodal disease to 18% and increasing the negative predictive value (NPV) of PET-CT to 89% in 1-way sensitivity analyses. In probabilistic sensitivity analysis, assuming a cost effectiveness threshold of $50,000 USD/QALY, END was dominant in 64% of simulations and cost effective in 69.8%. CONCLUSION: END is a cost-effective strategy compared with PET-CT in patients who have node-negative oral cancer. Although lower PET standardized uptake value thresholds would result in fewer false negatives and improved NPV, it is still uncertain that PET-CT would be cost effective, as this would likely result in more false positive tests.

A cost-utility analysis comparing CT surveillance, PET-CT surveillance, and planned postradiation neck dissection for advanced nodal HPV-positive oropharyngeal cancer.

BACKGROUND: The cost utility of image-guided surveillance using computed tomography (CT) and positron emission tomography (PET)-CT to planned postradiation neck dissection (PRND) was compared for the management of advanced nodal human papillomavirus-positive oropharyngeal cancer following chemoradiation. METHODS: A universal payer perspective was adopted. A Markov model was designed to simulate four treatment approaches with 3-month cycles over a lifetime horizon: 1) CT surveillance, 2) standard PET-CT surveillance, 3) a novel PET-CT approach with repeat PET at 6 months postchemoradiation for equivocal responders, and 4) PRND. Parameters including probabilities of CT nodal progression/resolution, PET avidity, recurrence, and survival were obtained from the literature. Costs were reported in 2019 Canadian dollars and utilities were expressed in quality-adjusted life years (QALYs). Deterministic and probabilistic sensitivity analyses were performed to evaluate model uncertainty. RESULTS: PET-CT surveillance dominated CT surveillance and PRND in the base case scenario, and the novel PET-CT approach was the most cost-effective strategy across a wide range of variables tested in one-way sensitivity analysis. On probabilistic sensitivity analysis, novel PET-CT surveillance was the most cost-effective strategy in 78.1% of model iterations at a willingness-to-pay of $50,000/QALYs. Novel PET-CT surveillance resulted in a 49% lower rate of neck dissection compared with traditional PET-CT, and yielded an incremental benefit of 0.14 QALYs with average cost savings of $1309. CONCLUSIONS: Image-guided surveillance including PET-CT and CT are more cost effective than PRND. The novel PET-CT approach with repeat PET for equivocal responders was the dominant strategy and yielded both higher benefit and lower costs compared with standard PET-CT surveillance.

Development and validation of a Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN-HN) in a scarce resource setting: Response to the COVID-19 pandemic.

BACKGROUND: In the wake of the coronavirus disease 2019 (COVID-19) pandemic, access to surgical care for patients with head and neck cancer (HNC) is limited and unpredictable. Determining which patients should be prioritized is inherently subjective and difficult to assess. The authors have proposed an algorithm to fairly and consistently triage patients and mitigate the risk of adverse outcomes. METHODS: Two separate expert panels, a consensus panel (11 participants) and a validation panel (15 participants), were constructed among international HNC surgeons. Using a modified Delphi process and RAND Corporation/University of California at Los Angeles methodology with 4 consensus rounds and 2 meetings, groupings of high-priority, intermediate-priority, and low-priority indications for surgery were established and subdivided. A point-based scoring algorithm was developed, the Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN-HN). Agreement was measured during consensus and for algorithm scoring using the Krippendorff alpha. Rankings from the algorithm were compared with expert rankings of 12 case vignettes using the Spearman rank correlation coefficient. RESULTS: A total of 62 indications for surgical priority were rated. Weights for each indication ranged from -4 to +4 (scale range; -17 to 20). The response rate for the validation exercise was 100%. The SPARTAN-HN demonstrated excellent agreement and correlation with expert rankings (Krippendorff alpha, .91 [95% CI, 0.88-0.93]; and rho, 0.81 [95% CI, 0.45-0.95]). CONCLUSIONS: The SPARTAN-HN surgical prioritization algorithm consistently stratifies patients requiring HNC surgical care in the COVID-19 era. Formal evaluation and implementation are required. LAY SUMMARY: Many countries have enacted strict rules regarding the use of hospital resources during the coronavirus disease 2019 (COVID-19) pandemic. Facing delays in surgery, patients may experience worse functional outcomes, stage migration, and eventual inoperability. Treatment prioritization tools have shown benefit in helping to triage patients equitably with minimal provider cognitive burden. The current study sought to develop what to the authors' knowledge is the first cancer-specific surgical prioritization tool for use in the COVID-19 era, the Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN-HN). This algorithm consistently stratifies patients requiring head and neck cancer surgery in the COVID-19 era and provides evidence for the initial uptake of the SPARTAN-HN.

Quality of life considerations for patients with anterior and central skull base malignancies.

INTRODUCTION: The extirpation of skull base malignancies may be associated with significant morbidity and can profoundly impact health related quality of life (HRQOL). In this review, we sought to provide an overview of HRQOL and the factors that influence it for patients with skull base malignancies. MATERIALS AND METHODS: Narrative review. RESULTS: HRQOL tends to improve in the months to years following treatment and is profoundly impacted by both tumor location and treatment approach. Wherever possible, HRQOL should always be elicited from the patient directly. Several HRQOL instruments have been used in this population including generic, site-specific and disease specific measures. CONCLUSION: Given that HRQOL is a multidimensional concept with several important facets, validated disease-specific instruments are generally preferred.

Tumor volumes in T3 supraglottic cancers treated with radiotherapy in the modern era: A study of the Canadian Head & Neck Collaborative Research Initiative.

PURPOSE: To evaluate the association of primary tumor volume (TV) with overall survival (OS) and disease-free survival (DFS) in T3 N0-3M0 supraglottic cancers treated with intensity-modulated radiotherapy (IMRT). METHODS: This was a retrospective cohort study involving 239 patients diagnosed with T3 N0-3M0 supraglottic cancers between 2002 and 2018 from seven regional cancer centers in Canada. Clinical data were obtained from the patient records. Supraglottic TV was measured by neuroradiologists on diagnostic imaging. Kaplan-Meier method was used for survival probabilities, and a restricted cubic spline Cox proportional hazards regression analysis was used to analyze TV associations with OS and DFS. RESULTS: Mean (SD) of participants was 65.2 (9.4) years; 176 (73.6%) participants were male. 90 (38%) were N0, and 151 (64%) received concurrent systemic therapy. Mean TV (SD) was 11.37 (12.11) cm3 . With mean follow up (SD) of 3.28 (2.60) years, 2-year OS was 72.7% (95% CI 66.9%-78.9%) and DFS was 53.6% (47.4%-60.6%). Increasing TV was associated (per cm3 increase) with worse OS (HR, 1.01, 95% CI 1.00-1.02, p < 0.01) and DFS (HR, 1.01, 95% CI 1.00-1.02, p = 0.02). CONCLUSIONS: Increasing primary tumor volume is associated with worse OS and DFS in T3 supraglottic cancers treated with IMRT, with no clear threshold. The findings suggest that patients with larger tumors and poor baseline laryngeal function may benefit from upfront laryngectomy with adjuvant radiotherapy.

Need for Tympanostomy Tubes in Children With Recurrent Acute Otitis Media Without Middle Ear Effusion.

OBJECTIVE: Children with recurrent acute otitis media (RAOM) presenting without middle ear effusion (MEE) do not meet indications for surgical intervention as outlined by Clinical Practice Guidelines (CPGs). The objective of this study was to determine which patients presenting with RAOM without MEE ultimately received tympanostomy tubes. STUDY DESIGN: Case series. SETTING: Single academic pediatric otolaryngology clinic. METHODS: Children (0-12 years) presenting with RAOM and no MEE were identified from October 2017 to December 2019. As per CPGs, no surgery was offered initially. Patients were given a semiurgent return appointment should they experience another suspected otitis media episode. If MEE was observed, tympanostomy tube insertion was offered. Patients were followed for 1-year following enrollment. RESULTS: One-hundred and twenty-four patients were included. The median age was 3.15 years old (interquartile range: 4.10). Seventy-five (60%) patients did not require additional follow-up and thus did not require tympanostomy tubes. Forty-nine (40%) patients were seen again; of these, 11 patients received tympanostomy tubes. Therefore, of patients presenting with no MEE, 91% did not require tympanostomy tubes. Patients who had surgery were younger on initial assessment than those who did not (mean difference 2.68 years, 95% confidence interval: 2.14-3.23). CONCLUSION: This study demonstrates the practical effect of adhering to CPGs for RAOM and suggests that many children may not require tympanostomy tube placement within the 1st year after the consultation if they did not initially present with MEE.

The impact of a cancer diagnosis on nonfatal self-injury: a matched cohort study in Ontario.

BACKGROUND: Psychological distress following a cancer diagnosis potentially increases the risk of intentional, nonfatal self-injury. The purpose of this work is to evaluate and compare rates of nonfatal self-injury among individuals in Ontario diagnosed with cancer against matched controls with no history of cancer. METHODS: Adults in Ontario diagnosed with cancer from 2007 to 2019 were matched to 2 controls with no history of cancer, based on age and sex. We calculated the absolute and relative difference in rates of nonfatal self-injury in the 5 years before and after the index date (date of cancer diagnosis and dummy date for controls). We used crude difference-in-differences methods and adjusted Poisson regression-based analyses to examine whether the change in rates of nonfatal self-injury before and after index differed between cancer patients and controls. RESULTS: The cohort included 803 740 people with cancer and 1 607 480 matched controls. In the first year after diagnosis, individuals with cancer had a 1.17-fold increase in rates of nonfatal self-injury (95% confidence interval [CI] 1.03-1.33) compared with matched controls, after accounting for pre-existing differences in rates of nonfatal self-injury and other clinical characteristics between the groups. Rates of nonfatal self-injury remained elevated in the cancer group by 1.07-fold for up to 5 years after diagnosis (95% CI 0.95-1.21). INTERPRETATION: In this study, incidence of nonfatal self-injury was higher among individuals diagnosed with cancer, with the greatest impact observed in the first year after diagnosis. This work highlights the need for robust and accessible psychosocial oncology programs to support mental health along the cancer journey.

Surgeon Thyroidectomy Case Volume Impacts Disease-free Survival in the Management of Thyroid Cancer.

OBJECTIVES: To assess the association between surgeons thyroidectomy case volume and disease-free survival (DFS) for patients with well-differentiated thyroid cancer (WDTC). A secondary objective was to assess a surgeon volume cutoff to optimize outcomes in those with WDTC. We hypothesized that surgeon volume will be an important predictor of DFS in patients with WDTC after adjusting for hospital volume and sociodemographic and clinical factors. METHODS: In this retrospective population-based cohort study, we identified WDTC patients in Ontario, Canada, who underwent thyroidectomy confirmed by both hospital-level and surgeon-level administrative data between 1993 and 2017 (N = 37,233). Surgeon and hospital volumes were calculated based on number of cases performed in the year prior by the physician and at an institution performing each case, respectively and divided into quartiles. A multilevel hierarchical Cox regression model was used to estimate the effect of volume on DFS. RESULTS: A crude model without patient or treatment characteristics demonstrated that both higher surgeon volume quartiles (p < 0.001) and higher hospital volume quartiles (p < 0.001) were associated with DFS. After controlling for clustering and patient/treatment covariates and hospital volume, moderately low (18-39/year) and low (0-17/year) volume surgeons (hazard ratios [HR]: 1.23, 95% confidence interval [CI]: 1.09-1.39 and HR: 1.34, 95% CI: 1.17-1.53 respectively) remained an independent statistically significant negative predictor of DFS. CONCLUSION: Both high-volume surgeons and hospitals are predictors of better DFS in patients with WDTC. DFS is higher among surgeons performing more than 40 thyroidectomies a year.

Quantifying Neck Fibrosis: Establishing the Domain Structure of the Neck Fibrosis Scale.

OBJECTIVE: We recently described the development of the Neck Fibrosis Scale (NFS). In this submission, we confirm domain structure and validate a scoring system for the NFS. STUDY DESIGN: Prospective cross-sectional study. METHODS: Between January 2020 and December 2021, 127 head and neck cancer patients with varying degrees of cutaneous neck fibrosis completed the original 15 item NFS. Exploratory factor analysis was used to identify optimal groupings with similar underlying factors. The association between the domains of the NFS and various measures of neck morbidity (i.e., construct validity) were assessed using gamma regression. RESULTS: Exploratory factor analysis confirmed 13 of the 15 items from the NFS mapped onto two factors, which were labelled 'physical' and 'emotional' domains. Of the remaining two items, 'energy' did not load uniquely onto one factor and was removed. 'Neck-swelling' did not load on either factor (loadings <0.3) but was retained within the physical domain based on clinical importance. This resulted in a revised 14-item questionnaire. Internal consistency for these two domains was high (>0.8, p < 0.01). Both the physical and emotional domains of the revised NFS show strong correlation with the neck dissection impairment index and neck range of motion. The physical domain strongly correlated with neck elasticity (0.902 [95%CI 0.839-0.972], p < 0.01). Patients receiving multimodal therapy had physical domain scores that were 31.6% [95% 13.9-51.8] higher (worse) than unimodal therapy patients. CONCLUSIONS: A domain structure and scoring strategy have been developed for the NFS. Future efforts should be directed toward an evaluation of responsiveness.

Gaps in Depression Symptom Management for Patients With Head and Neck Cancer.

OBJECTIVE: To understand practice patterns and identify care gaps within a large-scale depression screening program for patients with head and neck cancer (HNC). STUDY DESIGN: Retrospective cohort study. METHODS: This was a population-based study of adults diagnosed with a HNC between January 2007 and October 2020. Each patient was observed from time of first symptom assessment until end of study date, or death. The exposure of interest was a positive depressive symptom screen on the Edmonton Symptom Assessment System (ESAS). Outcomes of interest included psychiatry/psychology assessment, social work referral, or palliative care assessment. Cause specific hazard models with a time-varying exposure were used to investigate the exposure-outcome relationships. RESULTS: Of 14,054 patients with HNC, 9016 (64.2%) reported depressive symptoms on at least one ESAS assessment. Within 60 days of first reporting depressive symptoms, 223 (2.7%) received a psychiatry assessment, 646 (7.9%) a social work referral, and 1131 (13.9%) a palliative care assessment. Rates of psychiatry/psychology assessment (HR 3.15 [95% CI 2.67-3.72]), social work referral (HR 1.83 [95% CI 1.64-2.02]), and palliative care assessment (HR 2.34 [95% CI 2.19-2.50]) were higher for those screening positive for depression. Certain patient populations were less likely to receive an assessment including the elderly, rural residents, and those without a prior psychiatric history. CONCLUSION: A high proportion of head and neck patients report depressive symptoms, though this triggers a referral in a small number of cases. These data highlight areas for improvement in depression screening care pathways. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:2638-2646, 2023.

Association of Household Income at Diagnosis With Financial Toxicity, Health Utility, and Survival in Patients With Head and Neck Cancer.

Importance: While several studies have documented a link between socioeconomic status and survival in head and neck cancer, nearly all have used ecologic, community-based measures. Studies using more granular patient-level data are lacking. Objective: To determine the association of baseline annual household income with financial toxicity, health utility, and survival. Design, Setting, and Participants: This was a prospective cohort of adult patients with head and neck cancer treated at a tertiary cancer center in Toronto, Ontario, between September 17, 2015, and December 19, 2019. Data analysis was performed from April to December 2021. Exposures: Annual household income at time of diagnosis. Main Outcome and Measures: The primary outcome of interest was disease-free survival. Secondary outcomes included subjective financial toxicity, measured using the Financial Index of Toxicity (FIT) tool, and health utility, measured using the Health Utilities Index Mark 3. Cox proportional hazards models were used to estimate the association between household income and survival. Income was regressed onto log-transformed FIT scores using linear models. The association between income and health utility was explored using generalized linear models. Generalized estimating equations were used to account for patient-level clustering. Results: There were 555 patients (mean [SD] age, 62.7 [10.7] years; 109 [20%] women and 446 [80%] men) included in this cohort. Two-year disease-free survival was worse for patients in the bottom income quartile (<$30 000: 67%; 95% CI, 58%-78%) compared with the top quartile (≥$90 000: 88%; 95% CI, 83%-93%). In risk-adjusted models, patients in the bottom income quartile had inferior disease-free survival (adjusted hazard ratio, 2.13; 95% CI, 1.22-3.71) and overall survival (adjusted hazard ratio, 2.01; 95% CI, 0.94-4.29), when compared with patients in the highest quartile. The average FIT score was 22.6 in the lowest income quartile vs 11.7 in the highest quartile. In adjusted analysis, low-income patients had 12-month FIT scores that were, on average, 134% higher (worse) (95% CI, 16%-253%) than high-income patients. Similarly, health utility scores were, on average, 0.104 points lower (95% CI, 0.026-0.182) for low-income patients in adjusted analysis. Conclusions and Relevance: In this cohort study, patients with head and neck cancer with a household income less than CAD$30 000 experienced worse financial toxicity, health status, and disease-free survival. Significant disparities exist for Ontario's patients with head and neck cancer.
