Association of Delayed Time to Treatment Initiation With Overall Survival and Recurrence Among Patients With Head and Neck Squamous Cell Carcinoma in an Underserved Urban Population

Disparities in Care for Patients with Head and Neck Cancer

This article examines disparities in head and neck cancer across the cancer care continuum. It provides a public health lens to understand multilevel determinants of health behavior and the importance of social determinants of health. This article reviews the evidence base showing profound differences in incidence, treatment, and survival for patients with head and neck cancer by race, ethnicity, socioeconomic status, and geography. Continued research is needed to understand and address disparities for patients with head and neck cancer.

Transition to Medicare Does Not Contribute to Rise in Outpatient Visits for Nonmelanoma Skin Cancer, Actinic Keratosis, or Actinic Cheilitis in the US Population

BACKGROUND

Outpatient visits for nonmelanoma skin cancer (NMSC) and actinic keratoses (AK) have risen steadily in the United States, notably among Medicare beneficiaries. Individuals may delay seeking care for minimally symptomatic conditions until they qualify for Medicare coverage, indicating potential delay of nonurgent screening interventions for uninsured or underinsured patients younger than 65 years.

OBJECTIVE

This study investigates whether an atypical increase in outpatient visits for NMSC, AK, or actinic cheilitis (AC) occurs at the age of Medicare transition by utilizing the National Ambulatory Care Survey from 1993 to 2019.

MATERIALS AND METHODS

The National Ambulatory Care Survey data were analyzed for patients aged within 5 years of 65 years. Diagnoses were identified using International Classification of Diseases codes. Linear regression and outlier detection were used to identify a relationship between Medicare eligibility and outpatient visits for NMSC and AK/AC.

RESULTS

Predicted visits for AK/AC and NMSC increased with age. However, there was no evidence of a disproportionate increase in outpatient visits for NMSC and AK/AC at the age of Medicare eligibility.

CONCLUSION

Outside evidence indicates health care utilization increases after Medicare transition. This study's data do not support a corresponding rise in outpatient visits for NMSC and AK/AC at the age of Medicare eligibility.

Factors Contributing to Postoperative Radiotherapy Delays in Head and Neck Cancer: A Comprehensive Review

Head and neck cancer encompasses a diverse group of malignancies that pose significant challenges in their management due to their heterogeneity in clinical behavior and treatment response. Postoperative radiotherapy (PORT) is a critical component in the treatment regimen for head and neck cancer, aimed at reducing local recurrence and improving overall survival (OS). However, delays in the initiation of PORT can significantly compromise patient outcomes. This comprehensive review explores the factors contributing to such delays, categorizing them into patient-related, treatment-related, and systemic factors. Patient-related factors include health status, comorbidities, socioeconomic barriers, and psychological issues. Treatment-related factors involve surgical complications, complexities in treatment planning, and coordination challenges between surgical and radiation oncology teams. Systemic and institutional factors encompass hospital resources, staffing levels, administrative and insurance issues, and geographic barriers. The review also examined the impact of these delays on patient outcomes, highlighting the increased risk of recurrence and reduced survival rates. Strategies to mitigate delays are discussed, including improved preoperative and postoperative planning, enhanced multidisciplinary coordination, patient education, and systemic policy changes. Additionally, case studies and real-world examples of successful interventions are presented. Future directions for research and policy recommendations are also outlined, emphasizing the need for continued efforts to ensure timely PORT for head and neck cancer patients. This review aims to provide a comprehensive analysis that can inform clinical practice and policy, ultimately improving the standard of care and patient outcomes in head and neck cancer treatment.

Safety and efficacy of neoadjuvant chemotherapy with paclitaxel, carboplatin, and cetuximab for locally advanced head and neck squamous cell carcinoma

BACKGROUND

As a substantial waiting time is usually required for radical surgery, safe and effective preoperative neoadjuvant chemotherapy (NAC) is desired for the treatment of locally advanced head and neck squamous cell carcinoma (HNSCC). However, the significance of NAC in advanced HNSCC is still unclear. This study aimed to assess the safety and efficacy of NAC using the paclitaxel, carboplatin, and cetuximab (PCE) regimen.

METHODS

We retrospectively evaluated the background characteristics, incidence of adverse events, overall response rate (ORR), pathological response, recurrence-free survival (RFS), and overall survival (OS) in 26 patients. Patients receiving the PCE regimen were further divided into two groups based on the number of chemotherapy cycles (one cycle or more) and eligibility for cisplatin. Patients aged ≥ 75 years and those with an estimated glomerular filtration rate (eGFR) < 60 mL/min were classified as ineligible for cisplatin.

RESULTS

The median age was 70 (27-81) years. The median eGFR at treatment initiation was 63.2 (41.1-89.7) mL/min. Fourteen (53.8%) patients were ineligible for cisplatin. Grade 3 or higher neutropenia was observed in 11 of 25 (42.3%) patients. No delay in or withdrawal from surgery was observed. The ORR was 65.4%. The 2-year RFS and OS were 61.5% and 76.7%, respectively. No significant differences in safety and efficacy between the number of chemotherapy cycles and cisplatin eligibility were observed.

CONCLUSION

NAC using the PCE regimen for patients with locally advanced HNSCC, including cisplatin-ineligible patients, has acceptable toxicity and favorable efficacy.

Association of tumor growth rate with overall survival and recurrence among patients with laryngeal squamous cell carcinoma

BACKGROUND

Delay in time to treatment initiation (TTI) is associated with worsened survival outcomes in laryngeal squamous cell carcinoma (LSCC). It is unclear whether this is due to tumor growth or an increased risk of metastatic disease.

METHODS

This retrospective cohort study at one academic center included patients with LSCC who underwent radiotherapy/chemoradiotherapy between 2005 and 2017. We examined the association between tumor growth rate (TGR) and survival outcomes.

RESULTS

Among 105 patients (mean age, 63.8 ± 11.1 years; 72% male), the threshold between "slow-growing" and "fast-growing" tumors was >0.036 mL/day (survival) and >0.082 mL/day (recurrence). Faster growth was associated with worse overall survival (OS) (hazard ratio, 1.97; 95% confidence interval [CI], 0.94-4.13) and increased recurrence (odds ratio, 9.10; 95% CI, 2.40-34.4).

CONCLUSIONS

TGR >0.036 mL/day during TTI was associated with decreased OS, and >0.082 mL/day was associated with increased recurrence. Tumor measurement in patients experiencing delay may identify those who could benefit from escalated therapy.

Language barriers in head and neck cancer: Matched pair analysis of outcomes between non-English speaking and English-speaking patients

PURPOSE

As society grows in cultural diversity, an increasing proportion of patients are expected to be from non-English speaking backgrounds. This study sought to compare the clinical outcomes between non-English speakers and English speakers treated by radiation therapy for head and neck cancer.

METHODS AND MATERIALS

Seventy-five non-English speaking patients with squamous cell carcinoma of the head and neck were matched to English-speaking controls based on patient and disease variables; clinical outcomes were compared.

RESULTS

Non-English speaking patients had inferior 3-year overall survival (64% vs. 77%, p = 0.02) and progression-free survival (59% vs. 73%, p = 0.01) compared with the English-speaking cohort. On logistical regression, non-English-speaking status was associated with a significantly increased risk of overall death (OR = 1.41; 95% CI, 1.09-1.92).

CONCLUSIONS

Prognosis differed significantly between non-English speaking and English-speaking patients. Culturally tailored programs to address language barriers should be considered to ameliorate disparities in outcome.

Oral mucosal lesions triage via YOLOv7 models

BACKGROUND/PURPOSE

The global incidence of lip and oral cavity cancer continues to rise, necessitating improved early detection methods. This study leverages the capabilities of computer vision and deep learning to enhance the early detection and classification of oral mucosal lesions.

METHODS

A dataset initially consisting of 6903 white-light macroscopic images collected from 2006 to 2013 was expanded to over 50,000 images to train the YOLOv7 deep learning model. Lesions were categorized into three referral grades: benign (green), potentially malignant (yellow), and malignant (red), facilitating efficient triage.

RESULTS

The YOLOv7 models, particularly the YOLOv7-E6, demonstrated high precision and recall across all lesion categories. The YOLOv7-D6 model excelled at identifying malignant lesions with notable precision, recall, and F1 scores. Enhancements, including the integration of coordinate attention in the YOLOv7-D6-CA model, significantly improved the accuracy of lesion classification.

CONCLUSION

The study underscores the robust comparison of various YOLOv7 model configurations in the classification to triage oral lesions. The overall results highlight the potential of deep learning models to contribute to the early detection of oral cancers, offering valuable tools for both clinical settings and remote screening applications.

Association Between Social Determinants of Health and Cancer Treatment Delay in an Urban Population

PURPOSE

Delays in oncologic time to treatment initiation (TTI) independently and adversely affect disease-specific mortality. Social Determinants of Health (SDoH) are increasingly recognized as significant contributors to patients' disease management and health outcomes. Our academic center has validated a 10-item SDoH screener, and we elucidated which specific needs may be predictive of delayed TTI.

METHODS

This is a retrospective cohort study at an urban academic center of patients with a SDoH screening and diagnosis of breast, colorectal, endocrine/neuroendocrine, GI, genitourinary, gynecologic, head and neck, hematologic, hepatobiliary, lung, or pancreatic cancer from 2018 to 2022. Variables of interest included household income, tumor stage, and emergency department (ED) or inpatient admission 30 days before diagnosis. Factors associated with delayed TTI ≥45 days were assessed using multivariable logistic regression.

RESULTS

Among 2,328 patients (mean [standard deviation] age, 64.0 (12.8) years; 66.6% female), having >1 unmet social need was associated with delayed TTI (odds ratio [OR], 1.68; 95% CI, 1.54 to 1.82). The disparities most associated with delay were legal help, transportation, housing stability, and needing to provide care for others. Those with ED (OR, 0.49; 95% CI, 0.44 to 0.54) or inpatient (OR, 0.54; 95% CI, 0.50 to 0.58) admission 30 days before diagnosis were less likely to experience delay.

CONCLUSION

Delays in oncologic TTI ≥45 days are independently associated with unmet social needs. ED or inpatient admissions before diagnosis increase care coordination, leading to improved TTI. Although limitations included the retrospective nature of the study and self-reporting bias, these findings more precisely identify targets for intervention that may more effectively decrease delay. Patients with SDoH barriers are at higher risk of treatment delay and could especially benefit from legal, transportation, caregiver, and housing assistance.

Perspectives on Referral Pathways for Timely Head and Neck Cancer Care

Importance

Timely diagnosis and treatment are of paramount importance for patients with head and neck cancer (HNC) because delays are associated with reduced survival rates and increased recurrence risk. Prompt referral to HNC specialists is crucial for the timeliness of care, yet the factors that affect the referral and triage pathway remain relatively unexplored. Therefore, to identify barriers and facilitators of timely care, it is important to understand the complex journey that patients undertake from the onset of HNC symptoms to referral for diagnosis and treatment.

Objective

To investigate the referral and triage process for patients with HNC and identify barriers to and facilitators of care from the perspectives of patients and health care workers.

Design, Participants, and Setting

This was a qualitative study using semistructured interviews of patients with HNC and health care workers who care for them. Participants were recruited from June 2022 to July 2023 from HNC clinics at 2 tertiary care academic medical centers in Boston, Massachusetts. Data were analyzed from July 2022 to December 2023.

Main Outcomes and Measures

Themes identified from the perspectives of both patients and health care workers on factors that hinder or facilitate the HNC referral and triage process.

Results

In total, 72 participants were interviewed including 42 patients with HNC (median [range] age, 60.5 [19.0-81.0] years; 27 [64%] females) and 30 health care workers (median [range] age, 38.5 [20.0-68.0] years; 23 [77%] females). Using thematic analysis, 4 major themes were identified: the HNC referral and triage pathway is fragmented; primary and dental care are critical for timely referrals; efficient interclinician coordination expedites care; and consistent patient-practitioner engagement alleviates patient fear.

Conclusions and Relevance

These findings describe the complex HNC referral and triage pathway, emphasizing the critical role of initial symptom recognition, primary and dental care, patient information flow, and interclinician and patient-practitioner communication, all of which facilitate prompt HNC referrals.

Associations Between Race and Survival Outcomes Among Veterans With Head and Neck Cancer in a Racially Diverse Setting

Objective

There is limited data on the impact of clinical-demographic factors on survival outcomes among veterans with head and neck squamous cell carcinoma (HNSCC). This study was undertaken to evaluate the impact of race and other factors on overall survival (OS) in a population of veterans with HNSCC treated with curative intent.

Methods

Demographic and clinical data were collected on veterans with HNSCC treated with curative intent at our institution between 1999 and 2021. The primary outcome was 3-year OS. Secondary outcomes included treatment delay intervals, including time to treatment initiation (TTI), total package time, and duration of chemoradiation (DCRT).

Results

Of 260 veterans with HNSCC, black veterans had significantly lower 3-year OS (49.4%) compared to white veterans (65%, P = .019). Black veterans were also more likely to experience delays in treatment initiation (median TTI 46 vs 41 days; P = .047). Black patients were more likely to receive radiation alone (25.8% [black] vs 8.4% [white]; P < .001) and less likely to receive adjuvant therapy if treated surgically (11.1% [black] vs 22.4% [white]; P = .004), despite any statistically significant difference in stage of their tumor at presentation (Stage I: 21.2% [black] vs 19.6% [white]; P = .372); (Stage IV: 44.4% [black] vs 48.6% [white]; P = .487). Other factors associated with worse 3-year OS included older age (P = .023), lower body mass index (P = .026), neurocognitive disorder/dementia (P = .037), mental health disorders (P = .020), hypopharyngeal primary (P = .001), higher stage disease (P = .002), treatment type (P = .001), need for prophylactic gastrostomy tube (P = .048) or tracheotomy (P = .005), recurrent disease (P = .036), persistent disease (P < .001), distant metastases (P = .002), longer TTI (P = .0362), and longer DCRT (P = .004).

Discussion

Black race appears to be an independent predictor of 3-year OS in veterans with HNSCC. Further studies are warranted to determine the factors responsible for disparities in survival.

Implications for Practice

This study evaluated the ways in which race affects survival for US veterans with head and neck cancer. The authors found that black veterans had an increased risk of death compared to white patients, and also experienced delays when receiving treatment.

The impact of colonialism on head and neck cancer in Brazil: a historical essay focussing on tobacco, alcohol and slavery

Colonialism's enduring impact on Brazil has had significant implications for health and oncology outcomes. This historical essay delves into the profound changes brought about by the transatlantic slave trade from Africa to the Americas, particularly in terms of its influence on the economy, sociocultural habits, and health outcomes. This essay explores the enduring connections between the colonial period's operational dynamics in Brazil and the current epidemiological panorama of head and neck cancer (HNC). The examination provides original insights on the role of tobacco and alcohol production and consumption, alongside the investigation of structural racism, which contributes to disparities in access to diagnosis, treatment, and prognosis for patients with HNC. This article presents novel visions and an analysis of evidence-based strategies to disrupt the adverse impact of colonialism's legacy on the epidemiology of HNC in Brazil.

Differences in the association of time to treatment initiation and survival according to various head and neck cancer sites in a nationwide cohort

OBJECTIVES

To assess whether there are differences in the effects of time to treatment interval (TTI) on patient survival for head and neck cancer (HNC) sites in order to provide evidence that can support decision-making regarding prioritizing treatment.

MATERIALS AND METHODS

Patients in the Netherlands with a first primary HNC without distant metastasis between 2010 and 2014 were included for analysis (N = 10,486). TTI was defined as the time from pathologic diagnosis to the start of initial treatment. Overall survival (OS), cox regression analyses and cubic spline hazard models were calculated and visualized.

RESULTS

Overall, the hazard of dying was higher (HR = 1.003; 95 % CI 1.001-1.005) with each additional day until treatment initiation. The pattern, as visualized in cubic spline graphs, differed by site the hazard increased more steeply with increasing TTI for oral cavity cancer. For oropharyngeal and laryngeal cancer, a slight increase commenced after a longer TTI than for oral cavity cancer, while there was hardly an increase in hazard with increasing TTI for hypopharyngeal cancer.

CONCLUSION

The relationship between longer TTI and decreased survival was confirmed, but slight variations in the pattern of the hazard of dying by TTI by tumour site were observed. These findings could support decisions on prioritizing treatment. However, other aspects such as extent of treatment and quality of life should be investigated further so this can also be included.

Personal Social Networks and Care-Seeking for Head and Neck Cancer: A Qualitative Study

OBJECTIVES

To investigate the role of patients' personal social networks (SNs) in accessing head and neck cancer (HNC) care through patients' and health care workers' (HCWs) perspectives.

STUDY DESIGN

Qualitative study.

SETTING

Tertiary HNC centers at 2 academic medical centers, including 1 safety net hospital.

METHODS

Patients with newly diagnosed HNC, and HCWs caring for HNC patients, aged ≥18 years were recruited between June 2022 and July 2023. Semistructured interviews were conducted with both patients and HCWs. Inductive and deductive thematic analysis was performed with 2 coders (κ = 0.82) to analyze the data.

RESULTS

The study included 72 participants: 42 patients (mean age 57 years, 64% female, 81% white), and 30 HCWs (mean age 42 years, 77% female, 83% white). Four themes emerged: (1) Patients' SNs facilitate care through various forms of support, (2) patients may hesitate to seek help from their networks, (3) obligations toward SNs may act as barriers to seeking care, and (4) the SN composition and dedication influence care-seeking.

CONCLUSION

Personal SNs play a vital role in prompting early care-seeking among HNC patients. SN-based interventions could enhance care and improve outcomes for HNC patients.

Timely delivery of PORT for head and neck squamous cell carcinoma in a county hospital

Objectives

The objective of this study was to compare the rate of post-operative radiation therapy (PORT) initiation within 6 weeks for head and neck squamous cell carcinoma patients treated at a safety net, academic institutio between 2019 and 2021 versus those treated in 2022 after implementation of a new clinical pathway.

Methods

A retrospective case-control study was performed at a single tertiary care, safety-net, academic institution. Patient demographics, tumor characteristics, dates of surgery, and other treatment dates were collected from the electronic medical record. The time from surgery to PORT was calculated. Patients who started radiation treatment within 42 days of surgery were regarded as having started PORT on time. The demographics, tumor characteristics, and rate of timely PORT for the two cohorts of patients were compared.

Results

From 2018 to 2021, our rate of PORT initiation within 6 weeks of surgery was 12% (n = 57). In 2022, our rate of timely PORT was 88% (n = 16), p < 0.5. Patient demographics and characteristics were similar with the exception of marital status and use of free-flap reconstruction. The 2022 cohort was more likely to be single (p < 0.5), and all patients underwent free-flap reconstruction in 2022 (p < 0.05).

Conclusion

Early referrals, frequent communication, and use of a secure registry were the key to the success found by our group despite the socioeconomic challenges of our underserved, safety-net hospital patient population. The changes made at our institution should serve as a template for other institutions seeking to improve the quality of care for their HNSCC patients.

Diagnostic adequacy and accuracy of surgeon-performed ultrasound guided fine needle aspiration in lateral neck masses

BACKGROUND

Surgeon-performed ultrasound guided fine needle aspiration (SUS-FNA) reduces the time to diagnosis and treatment of head and neck pathology. Although it has been validated in the investigation of thyroid pathology, there is a paucity of evidence to support its use in lateral neck masses. This study aims to determine the accuracy and adequacy of SUS-FNA in the investigation of lateral neck masses.

METHODS

A retrospective cohort analysis was performed of patients who underwent a SUS-FNA for lateral neck mass between June 2018 and October 2022 at a single institution. Pathologist reports were reviewed to determine the rate of FNA sample adequacy. A comparison was made between FNA cytology results and final histopathological diagnosis following surgical excision in a subset of patients to determine FNA accuracy.

RESULTS

A total of 110 SUS-FNAs were performed on lateral neck masses. Diagnostic adequacy of SUS-FNA was determined to be 91% (100/110). When analysing the subset of patients who proceeded to surgical excision, the diagnostic accuracy of SUS-FNA was determined to be 88% (38/43).

CONCLUSION

SUS-FNA results in high adequacy rates with good diagnostic accuracy in the investigation of lateral neck masses. This tool has great potential in reducing treatment delay in the management of head and neck cancer.

The impact of the pandemic on the presentation and treatment of head and neck squamous cell carcinoma at a county hospital

INTRODUCTION

In March 2020, the World Health Organization declared COVID-19 a pandemic, initiating stay-at-home orders which delayed cancer care and screening. The impact on head and neck cancer care in populations at risk has yet to be elucidated. The objective of this investigation is to evaluate how the presentation, diagnosis, and treatment of head and neck squamous cell carcinoma cancer patients at a county hospital were affected by the pandemic.

METHODS

A retrospective review of patients with head and neck squamous cell carcinoma that were diagnosed at a county hospital 365 days before and after stay-at-home orders were initiated. The primary outcomes were duration between diagnosis from imaging and initiation of treatment. Secondary outcomes included mortality, stage, nodal status, and distant metastasis at presentation.

RESULTS

There was a total of 105 diagnoses. Sixty-five (62 %) head and neck squamous cell carcinoma diagnoses were diagnosed before the stay-at-home orders were initiated, and 40 (38 %) after. Eighty percent (32/40) of diagnoses presenting after had stage IV disease compared to 58 % (38/65) in those before (p < 0.05). A higher percentage of patients who presented later had a >30-day delay to biopsy (43 % v. 20 %, OR: 3.0, p < 0.05). This difference was exacerbated by those with laryngeal, oral cavity, or oropharyngeal cancer (45 % v. 15 %, OR: 4.5, p < 0.05). There was a larger delay from diagnosis to treatment after the orders were initiated (68 v. 53, p < 0.05) however there was no difference in one-year mortality (25 % v. 23 %, p > 0.05). This investigation found a 14 % loss to follow-up.

CONCLUSIONS AND RELEVANCE

In this cohort of head and neck squamous cell carcinoma diagnoses at a county hospital, those diagnosed after the stay-at-home orders were initiated presented with more advanced disease. They also had more delays in diagnosis and initiation of treatment. There was no difference in one-year mortality rates between the two groups however there was a significant loss to follow-up, limiting prognostication. These findings serve to better prepare healthcare providers to implement optimized care during future shutdowns related to public health crises.

Hospital factors determining overall survival in cancer patients undergoing curative treatment

BACKGROUND

In oncology, overall survival (OS) and quality of life (QoL) are key indicators. The factors that affect OS and QoL include tumor-related characteristics (stage and grade), patient-related factors (performance status and comorbidities), and cancer-directed therapy (CDT)-related aspects. In addition, external factors such as governance or policy (e.g., inaccessibility to CDT, increased distance to service, poor socioeconomic status, lack of insurance), and hospital-related factors (e.g., facility volume and surgeon volume) can influence OS and QoL.

MATERIALS AND METHODS

The primary objective of this narrative review was to identify hospital-related factors that affect OS and QoL in patients receiving curative CDT. The authors defined extrinsic factors that can be modified at the hospital level as "hospital-related" factors. Only factors supported by randomized controlled trials (RCT), systematic reviews (SR) and/or meta-analyses (MA), and population database (PDB) analyses that address the relationship between OS and hospital factors were considered.

RESULTS

The literature review found that high hospital or oncologist volume, adherence to evidence-based medicine (EBM), optimal time-to-treatment initiation (TTI), and decreased overall treatment time (OTT) increase OS in patients undergoing curative CDT. The use of case management strategies was associated with better symptom management and treatment compliance, but had a mixed effect on QoL. The practice of enhanced recovery after surgery (ERAS) in cancer patients did not result in an increase in OS. There was insufficient evidence to support the impact of factors such as teaching or academic centers, hospital infrastructure, and treatment compliance on OS and QoL.

CONCLUSION

The authors conclude that hospital policies should focus on increasing hospital and oncologist volume, adhering to EBM, optimizing TTI, and reducing OTT for cancer patients receiving curative treatment.

Impact of time-to-surgery on survival and quality of life in oral cancer

PURPOSE

To investigate the association between time-to-surgery (TTS) and overall survival (OS), disease specific survival (DSS) and quality of life (QoL) in patients with oral squamous cell carcinoma (OSCC).

MATERIALS AND METHODS

116 patients with OSCC candidate to surgery were examined. TTS intervals starting from diagnosis (TTS-clinical-based) and from histological reports (TTS-biopsy-based) were calculated. The effects of TTS intervals and prognostic factors on 5-year OS and DSS were explored.

RESULTS

In our cohort advanced T-categories OSCCs with TTS < 30 days showed a trend to have higher DSS rate (p = 0.049). Patients with TTS-clinical-based < 30 days showed better postoperative QoL. Positive surgical margins, nodal involvement (pN+), DOI >10 mm, invasive surgery and extra-capsular extension in pN+ were found to be significantly associated with a poor OS and DSS.

CONCLUSIONS

TTS ≥ 30 days can adversely affect DSS, especially in the advanced T categories. Short TTS intervals resulted associated with a better postoperative QoL.

Prognostic significance of time trends in treatment of head and neck squamous cell carcinoma

PURPOSE

To analyze the impact of demographic, clinical, and management variables on time to treatment initiation (TTI) and overall survival (OS).

STUDY DESIGN

Retrospective chart review.

MATERIALS AND METHODS

Medical records of patients diagnosed with head and neck cancer from 2018 to 2020 were reviewed. Univariate linear and Cox-regressions identified predictors of TTI and OS. Kaplan Meier (KM) curves assessed the difference in survival by diagnostic year and TTI.

RESULTS

381 patients met eligibility criteria. Median TTI was 35.0 days (IQR: 25.0-49.0). Only 10.8 % of all patients reported any treatment delay, with TTI exceeding 90 days found in 3.7 % of patients. TTI increased with African American race (p = 0.02), ED referrals (p = 0.02), and direct admission status (p = 0.01). When compared to treatment with surgery alone, TTI was shorter in patients undergoing surgery with adjuvant radiation (p = 0.02), adjuvant chemoradiation (p = 0.04), and salvage surgery (p = 0.04). Univariate Cox-regressions found smoking (p = 0.01), direct admission status (p = 0.02), increased duration of symptoms (p = 0.02), placement of PEG tubes (p < 0.01) and tracheostomies (p < 0.01), combination treatment (p < 0.01), and surgery with adjuvant chemoradiation treatment (p = 0.01) to increase mortality risk. Disease characteristics, including tumor size (p < 0.01), presence of nodal disease (p = 0.02), and late-stage disease (p < 0.01), increased mortality risk. TTI and diagnostic year did not impact survival.

CONCLUSIONS

Our analysis determined several demographic, referral, and treatment factors impacted TTI. However, increased TTI did not impact survival. Characteristics consistent with advanced disease worsened OS. Despite the pandemic burden, patients diagnosed in 2020 showed no difference in short-term survival compared to prior years.

Factors Affecting the Compliance of Curative-Intent Treatment in Patients With Head and Neck Cancer

Objectives: This study aims to investigate the factors that lead to poor compliance in initiating the treatment in patients with newly diagnosed head and neck cancers. Methods: A total of 193 patients from the head and neck cancer database dated from January 1, 2018 to September 30, 2020, were analyzed. Variables analyzed included age, gender, primary cancer site, T stage, N stage, M stage, overall stage (I-IV), patient's residential distance, and the impact of COVID-19. Univariate and multivariate analyses were used to assess the significance of these variables in relation to the time to receiving on-time treatment as recommended by specialists. Results: Upon multivariate analysis, the advanced stage and residential distance were significantly associated with initial compliance (P < .09). The impact of nasopharyngeal carcinoma (NPC) and COVID-19 shows a borderline significance (P = .224 and P = .184). Conclusions: The overall stage and patient living distance to the healthcare facility, patient with NPC, and the impact of COVID-19 might affect the compliance of initiating a curative-intent treatment in patients with newly diagnosed head and neck cancers.

Effect of Waiting Time for Radioactive Iodine Therapy on Outcome in N1 Stage Papillary Thyroid Cancer

CONTEXT

The waiting time for radioactive iodine therapy (WRAIT) after total thyroidectomy (TT) in patients with papillary thyroid cancer (PTC) and lymph node metastases (N1) has not been sufficiently investigated for risk of adverse outcomes.

OBJECTIVE

This work aimed to estimate the effect of WRAIT on the outcomes of disease persistence and recurrence among patients with N1 PTC and investigate factors predictive of delayed radioactive iodine therapy (RAIT).

METHODS

This retrospective cohort study was conducted in a university hospital. A total of 909 patients with N1 PTC were referred for RAIT between 2014 and 2018. WRAIT is the duration between TT and initial RAIT. The optimal WRAIT threshold determined using recursive partitioning analysis was used to define early and delayed RAIT. The primary end point was tumor persistence/recurrence. We compared the outcomes of patients with early and delayed RAIT using inverse probability weighting based on the propensity score.

RESULTS

The WRAIT threshold that optimally differentiated worse long-term remission/excellent response outcomes was greater than 88 days (51% of our cohort; n = 464). WRAIT exceeding 88 days was associated with an augmented risk of disease persistence/recurrence (odds ratio, 2.47; 95% CI, 1.60-3.82) after adjustment. Predictors of delayed RAIT included residence in lower-income areas, reoperation before the initial RAIT, TT at a nonuniversity-affiliated hospital, multifocality, extrathyroidal extension, N1b disease, and pre-RAIT-stimulated thyroglobulin level less than 1 ng/mL.

CONCLUSION

Delayed RAIT beyond 88 days after TT in patients with N1 PTC independently increased the risk of disease persistence/recurrence. Evaluation of the predictive determinants of prolonged WRAIT may help target at-risk patients and facilitate interventions.

Factors affecting timeliness in management of head and neck cancer

BACKGROUND

Timeliness in the management of patients with head and neck cancer (HNC) can be affected by both patient and non-patient related factors. This study aims to investigate the factors associated with the timeliness of managing HNC.

METHODS

A retrospective review was conducted on Western Health medical records including all new patients presenting to the Western Health HNC surgical outpatient clinic in the five-year period from first January 2017 to 31st December 2021 with the diagnosis of a HNC. Both patient and non-patient related factors were compared with the duration between a patient's referral to a HNC service and the commencement of their treatment.

RESULTS

Two hundred and twenty-eight patients were included in this study. The median duration from referral to the commencement of treatment was 48 days. Lack of radiological or pathological investigations prior to referral to a HNC service as well as early staging were found to significantly impact timeliness in management. Socioeconomic factors such as non-English speaking backgrounds, distance from the hospital and lack of social supports were not found to negatively impact timeliness of management.

CONCLUSION

The management of patients with HNC require careful consideration of all patient and non-patient related factors which may affect timeliness in management, particularly investigations performed prior to their referral to a HNC service.

Patient delay and its clinical significance among head and neck cancer patients in Hungary

Introduction: Head and neck cancers represent a major health problem in Hungary. With their high incidence and mortality rates, Hungary is one of the world leaders in these indicators. The length of patient delay, defined as time from onset of symptoms to first medical consultation, is unknown in Hungarian patients with head and neck cancer. We aimed to use a representative sample of the Hungarian head and neck cancer patient population to determine patient delay according to disease localization and stage and to identify correlations with other clinical parameters. Methods: In our retrospective study, we reviewed patient documentation. For the inclusion, the patients had to be diagnosed with malignant tumors of the oral cavity, oropharynx, hypopharynx or larynx at the Department Head and Neck Surgery of Semmelweis University between 2012 and 2017. Results: We identified 236 patients who met the inclusion criteria. The median delay was 9.5 weeks (range 0-209 weeks) and the mean delay of patients was 17.57 weeks (SD 23.67). There was a significant difference in patient delay data by location. Among glottic cancers, the most common diagnosis was an early stage (67%), compared with other localizations, including most commonly the oropharynx (81%) and hypopharynx (80%), where a locoregionally advanced stage was more frequent. Discussion: Compared to data from different countries, the delay of Hungarian patients with head and neck cancer is significantly longer, which may contribute to the high mortality in Hungary. Screening and patient education in high-risk groups could contribute to earlier diagnosis and thus improve prognosis.

Missed cancer in the Danish head and neck cancer fast-track program: results from a tertiary cancer center

BACKGROUND

The Danish head and neck cancer fast-track program is a national standardized pathway aiming to reduce waiting time and improve survival for patients suspected of cancer in the head and neck (HNC). Until now, the frequency of missed cancer in the fast-track program has not been addressed. A missed cancer leads to treatment delay and may cause disease progression and worsening of prognosis. The study objective was to estimate the frequency of patients with missed cancers in the Danish HNC fast-track program and to evaluate the accuracy of the program.

MATERIALS AND METHODS

Patients who were rejected from the HNC fast-track program because cancer was not found between 1 July 2012 and 31 December 2018 at Odense University Hospital, Denmark were included and followed for three years. Patients were categorized into groups depending on the diagnostic evaluation. Group 1 included patients evaluated with standard clinical work-up without imaging and biopsy. Group 2 included patients evaluated with imaging and/or biopsy in addition to the standard clinical work-up. The local cancer database and electronic patient records were reviewed to determine if a missed cancer had occurred within the follow-up period.

RESULTS

A total of 8345 HNC fast-track courses were initiated during the study period. 1499 were patients suspected of recurrent cancer and were excluded leaving 6846 patients to be assessed for eligibility. Of these, 3752 patients were rejected because cancer was not found. Ten patients were subsequently diagnosed with cancer within the follow-up period resulting in an overall frequency of 0.15%. For group 1 and 2, the frequency was 0.04% and 0.10%, respectively. The sensitivity of the fast-track program was 99.67% and the negative predictive value was 99.73%.

CONCLUSION

The frequency of missed cancer in a tertiary HNC center following the Danish fast track program is low.

Association of Social-Ecological Factors With Delay in Time to Initiation of Postoperative Radiation Therapy: A Prospective Cohort Study

Importance

Timely initiation of postoperative radiation therapy (PORT) is associated with reduced recurrence rates and improved overall survival in patients with head and neck squamous cell carcinoma (HNSCC). Measurement of the association of social-ecological variables with PORT delays is lacking.

Objective

To assess individual and community-level factors associated with PORT delay among patients with HNSCC.

Design, Setting, and Participants

This prospective cohort study carried out between September 2018 and June 2022 included adults with untreated HNSCC who were enrolled in a prospective registry at a single academic tertiary medical center. Demographic information and validated self-reported measures of health literacy were obtained at baseline visits. Clinical data were recorded, and participant addresses were used to calculate the area deprivation index (ADI), a measure of community-level social vulnerability. Participants receiving primary surgery and PORT were analyzed. Univariable and multivariable regression analysis was performed to identify risk factors for PORT delays.

Exposures

Surgical treatment and PORT.

Main Outcomes and Measures

The primary outcome was PORT initiation delay (>42 days from surgery). Risk of PORT initiation delay was evaluated using individual-level (demographic, health literacy, and clinical data) and community-level information (ADI and rural-urban continuum codes).

Results

Of 171 patients, 104 patients (60.8%) had PORT delays. Mean (SD) age of participants was 61.0 (11.2) years, 161 were White (94.2%), and 105 were men (61.4%). Insurance was employer-based or public among 65 (38.5%) and 75 (44.4%) participants, respectively. Mean (SD) ADI (national percentile) was 60.2 (24.4), and 71 (41.8%) resided in rural communities. Tumor sites were most commonly oral cavity (123 [71.9%]), with 108 (63.5%) classified as stage 4 at presentation. On multivariable analysis, a model incorporating individual-level factors with health literacy in addition to community-level factors was most predictive of PORT delay (AOC= 0.78; R2, 0.18).

Conclusions and Relevance

This cohort study provides a more comprehensive assessment of predictors of PORT delays that include health literacy and community-level measures. Predictive models that incorporate multilevel measures outperform models with individual-level factors alone and may guide precise interventions to decrease PORT delay for at-risk patients with HNSCC.

Predictive Factors for Cancer Treatment Delay in a Racially Diverse and Socioeconomically Disadvantaged Urban Population

PURPOSE

Incremental delays in time to treatment initiation (TTI) have been shown to cause a proportional, increased independent risk of disease-specific mortality for breast cancer, colorectal cancer (CRC), head and neck cancer (HNC), non–small-cell lung cancer (NSCLC), and pancreatic cancer. Studies suggest that delays are associated with racial and socioeconomic disparities. We evaluated associations between patient factors and TTI to identify those associated with delay.

MATERIALS AND METHODS

This is a retrospective cohort study at an urban community-based academic center of patients diagnosed with or referred for curative-intent treatment of breast cancer, CRC, HNC, NSCLC, and pancreatic cancer from January 2019 to December 2021. Variables of interest included Charlson Comorbidity Index (CCI) score, insurance type, language preference, and inpatient admission 30 days before diagnosis. Factors associated with TTI delay, defined as TTI ≥ 30 days, were assessed using multivariable logistic regression.

RESULTS

Among 2,543 patients (69% female), the mean age was 63.4 years and the median TTI was 25 days (IQR, 6-44). Within multivariable models, patients treated as outpatient and not admitted 30 days before diagnosis experienced statistically significant greater delay for CRC (odds ratio [OR], 2.82; 95% CI, 1.71 to 4.66) and NSCLC (OR, 2.11; 95% CI, 1.31 to 3.39). Higher CCI score was associated with delay for HNC (OR, 2.63; 95% CI, 1.04 to 6.66) and NSCLC (OR, 1.75; 95% CI, 1.14 to 2.71). For breast cancer, uninsured and Spanish-speaking patients (OR, 1.79; 95% CI, 1.21 to 2.67) experienced increased TTI.

CONCLUSION

Care coordination/compliance (eg, inpatient 30 days before diagnosis), clinical (eg, medical comorbidities), and socioeconomic (eg, uninsured status) predictors for delayed TTI were identified and may inform delay minimizing interventions. Our data support evidence that TTI delays are associated with demographic and socioeconomic disparities. Existing disparities are likely exacerbated by delays that disproportionately affect patients with care coordination/compliance issues, multiple comorbidities, and lower socioeconomic status.

Lung Cancer Screening Penetration in an Urban Underserved County

PURPOSE

To compare residential geography, sex, socioeconomic status (SES), and race/ethnicity of patients screened at Montefiore's Lung Cancer Screening Program with those of patients diagnosed with lung cancer, assessing whether screening efforts are appropriately focused.

METHODS

This retrospective cohort study involved patients within a multisite urban medical center undergoing lung cancer screening or diagnosed with lung cancer from January 1, 2015 to December 31, 2019. Inclusion criteria were residence within the Bronx, NY and age between 55 and 80 years. Institutional review board approval was obtained. Data were analyzed using the Wilcoxon two-sample t test and χ².

RESULTS

The cohorts comprised 1568 (50.3%) women and 1551 (49.7%) men (mean age 65.6 ± 6.16). The Southeast Bronx had the most diagnosed lung cancers (29.96%) and screenings (31.22%). Sex did not significantly differ (p = 0.053). Cancer and screening cohorts were from impoverished neighborhoods with mean SES of - 3.11 ± 2.78 and - 3.44 ± 2.80 (p < 0.01). The lower tier SES neighborhoods demonstrated more patients in the screening cohort than cancer cohort (p = 0.01). Both cohorts included a majority of Hispanic patients, although race/ethnicity differed significantly (p = 0.01). Lower SES neighborhoods showed no significant difference in race/ethnicity between cancer and screening cohorts (p = 0.262).

CONCLUSION

Though statistically significant differences were found between cohorts, likely due to sample size, few clinically meaningful differences were found, implying our lung cancer screening program was effective in reaching the desired population. Demographics-based programs should be considered in global efforts to screen vulnerable populations.

Oral cancer care in the "Metropolitan I" health region in the state of Rio de Janeiro, Brazil: enabling and constraining factors

The aim was to identify constraining and enabling factors related to the organization of health care networks that influence access to oral cancer diagnosis and treatment. A case study in the "Metropolitan I" health region using data collected from health information systems and 26 semi-structured interviews with health managers and professionals. The data were analyzed using descriptive statistics and strategic conduct analysis, drawing on the theory of structuration proposed by Giddens. The findings reveal that coverage of oral health care in primary care services is generally low and prioritizes specific groups and urgent cases, hampering access to oral cancer diagnosis. While the presence of a network of secondary care services in the municipalities that make up the health region facilitates diagnosis, there are major barriers to treatment. Informal partnerships established with dental schools play an important role in diagnosis, but do not receive funding. The regulation of appointments for diagnosis was not restrictive. In contrast, the regulation of referrals for treatment lacked transparency, was subject to long delays, and shortage of places. Despite advances, constraining factors related to structure and the actions of agents involved in the care process persist, hampering the timely diagnosis and treatment of oral cancer.

Assessing the role of ultrasound for the evaluation of adult neck masses

Objectives

The American Academy of Otolaryngology clinical practice guidelines recommend cross-sectional imaging or fine needle aspiration for any neck mass in an adult that persists beyond 2 weeks that is not convincingly related to a bacterial infection. We aimed to assess the role of ultrasound in the evaluation and management of neck masses.

Methods

A retrospective chart review was performed of adult patients evaluated in the Otolaryngology clinic at a single institution from December 2014 to December 2015 for a visible or palpable neck mass persistent beyond 2 weeks who had an ultrasound exam as part of their initial workup. Patients with a history of head and neck malignancy or those presenting wtih primary salivary or thyroid gland lesions were excluded. Sonographic features, demographics, imaging, and biopsy results were recorded.

Results

Of the 56 patients who met inclusion criteria, 36 (64.3%) received FNA or biopsy, of which 18 (50%) demonstrated malignant pathology. Twenty patients (35.7%) demonstrated benign features on ultrasound and did not undergo tissue sampling. Two of these 20 patients underwent subsequent cross-sectional imaging. Eight of these 20 patients were followed with serial ultrasound with an average of 3 exams over 14.7 months. The remaining 12 patients had spontaneous resolution of their adenopathy. None of these 20 patients was subsequently diagnosed with malignancy.

Conclusion

In this study, approximately one third of patients presenting with a visible or palpable neck mass were able to safely avoid cross-sectional imaging and/or tissue sampling when ultrasound demonstrated features consistent with benign pathology. Our results suggest that ultrasound can play a useful role in the initial evaluation and management of adults presenting with a neck mass.

Impact of the COVID-19 Pandemic on Brazilian Head and Neck Surgery Centers

OBJECTIVE

The outbreak of the COVID-19 pandemic had a considerable impact on the healthcare access, treatment, and follow-up of oncologic patients. The aim of this study was to evaluate how the COVID-19 pandemic has affected consultation and follow-up demand as well as treatment volume at Brazilian Head and Neck Surgery centers.

METHODS

An anonymous online questionnaire was used for collection of data across all Brazilian Head and Neck Surgery Centers across a 3-month period (April‒June 2021). This information included the characteristics of each center, and the perceived self-reported impact of the COVID-19 pandemic on academic activities, residency training, and the diagnosis, treatment, and follow-up of patients with Head and Neck diseases between 2019 and 2020.

RESULTS

The response rate across the 40 registered Brazilian Head and Neck Surgery Centers was 47.5% (n=19). The data showed a significant reduction in the total number of consultations (24.8%) and number of attending patients (20.2%) between 2019 and 2020. The total number of diagnostic exams (31.6%) and surgical procedures (13.0%) conducted over this period also decreased significantly.

CONCLUSIONS

The COVID-19 pandemic had a significant national impact on Brazilian Head and Neck Surgery Centers. Future studies should examine the long-term effects of the pandemic on cancer treatment.

Specialty pharmacy turnaround time impediments, facilitators, and good practices

BACKGROUND: Patients receiving specialty medications have conditions that are often complex, high cost, and high need. Prompt treatment initiation is essential for the appropriate management of many conditions treated by specialty products. Improving the turnaround time (TAT) of specialty pharmacy prescriptions helps ensure patients receive the medication they need in the necessary time frame to optimize health outcomes. Despite a clinical justification for improved TAT, there is a gap in the literature describing what factors impact these times. OBJECTIVE: To determine factors that may influence specialty pharmacy TATs and to identify good practices that specialty pharmacies use to improve TAT. METHODS: This qualitative study used 4 focus groups with specialty pharmacy subject matter experts. Each focus group represented different specialty pharmacy types, including health system, payer-associated, retail chain, and independent specialty pharmacies. Attitudes, beliefs, and experiences regarding specialty pharmacy TAT were captured. Open-ended questions and prompts eliciting impediments, facilitators, and good practices associated with specialty pharmacy TAT were asked of participants. Data were analyzed thematically. RESULTS: Fifteen individuals participated across 4 focus groups: payer-associated (n = 4), independent (n = 3), health system (n = 5), and retail chain (n = 3) specialty pharmacies. Average TATs varied across specialty pharmacy type and by prescription type (clean vs intervention). Several interconnected themes were identified, including barriers with health benefits formulary management, prior authorization delays, differences in requirements between managed care organizations, and miscommunication with physicians, among others. Five subthemes were identified during the discussion of factors influencing TAT, including patient characteristics, pharmacy characteristics, provider characteristics, clinical situations, and health benefit design and formulary considerations. Pharmacy workflow improvements through technology integration are thought to improve TAT. In addition, participants noted facilitators including specialization among pharmacists and technicians in certain diseases, particularly hepatitis C and cancer. Some good practices included using patient financial advocates, technology integration, and a structured patient onboarding process, which were found to minimize delays caused by prior authorization, communication, and formularies. CONCLUSIONS: A multitude of factors impacting specialty pharmacy prescription TAT were identified. Multidisciplinary coordination between pharmacies, physicians, and managed care organizations is essential to ensure patients receive medications in the necessary time frame to optimize health outcomes. DISCLOSURES: This study was conducted with support from Pfizer.

Tendência Temporal e Distribuição Espacial da Mortalidade por Câncer de Boca em Sergipe

Introdução: Anualmente, no Brasil, 15 mil pessoas são diagnosticadas com câncer de boca, e quase metade delas morre. Sergipe está entre os sete Estados brasileiros com maiores índices. Objetivo: Analisar a tendência temporal e a distribuição espacial da mortalidade por câncer de boca em Sergipe entre 2007 e 2016. Método: Estudo ecológico de série temporal de base populacional, utilizando técnicas de análise espacial. Os dados de mortalidade foram obtidos no Sistema de Informação sobre Mortalidade (SIM). A análise das tendências temporais foi realizada no modelo de regressão de Joinpoint por meio da regressão de Poisson. Foram realizadas análises espaciais utilizando o estimador de intensidade Kernel e os índices de Moran Global e Local. Resultados: Foram analisadas 543 mortes por câncer de boca. Os casos mais frequentes ocorreram em homens (74%), com idade média de 64 anos e baixa escolaridade. As taxas de mortalidade global (variação percentual anual ‒ APC=2,5; IC 95% 0,9-6,7) e masculina (APC=2,96; IC 95% 1,2-5,6) aumentaram. Houve também uma tendência crescente de mortalidade por câncer na língua (APC=10,05; IC 95% 3,8-16,7). A mortalidade relacionada a outras localizações anatômicas foi estável. Houve concentração de óbitos nas Regiões Metropolitana, Centro-Sul e Centro-Agreste. Conclusão: Durante o período analisado, a taxa de mortalidade geral mostrou uma tendência crescente, com concentração nas Regiões Centro-Sul, Central e Metropolitana, sendo necessário manter medidas de prevenção e controle contra o câncer de boca em todo o Estado de Sergipe.

The effect of treatment delay on quality of life and overall survival in head and neck cancer patients

Objective

Head and neck squamous cell carcinomas (HNSCC) are rapidly developing tumours, and substantial delay in treatment initiation is associated with decreased overall survival. The effect of delay on health‐related quality of life (HRQOL) is unknown. The aim of this study was to assess the impact of delay on QOL and overall survival.

Methods

Patients with mucosal HNSCC were prospectively included. HRQOL and 2‐year overall survival were analysed using linear mixed‐model analyses and cox regression, respectively. Delay was defined as care pathway interval (CPI) of ≥30 days between first consultation and treatment initiation.

Results

Median CPI was 39 days for the 173 patients included. A trend towards higher HRQOL‐scores (indicating better HRQOL) during 2‐year follow‐up for patients with delay in treatment initiation was visible in the adjusted models (HRQOL summary score—β: 2.62, 95% CI: 0.57–4.67, p = 0.012). Factors associated with decreased overall survival were moderate comorbidities (HR: 5.10, 95% CI: 1.65–15.76, p = 0.005) and stage‐IV tumours (HR: 12.37, 95% CI: 2.81–54.39, p = 0.001). Delay was not associated with worse overall survival.

Conclusion

Timely treatment initiation is challenging, especially for patients with advanced tumours and initial radiotherapy treatment. Encountering delay in treatment initiation did not result in clinically relevant differences in HRQOL‐scores or decreased overall survival during 2‐year follow‐up.

Factors Associated With a Prolonged Diagnosis-to-Treatment Interval in Laryngeal Squamous Cell Carcinoma

OBJECTIVE

Evaluate factors associated with treatment delays and their effect on survival in laryngeal squamous cell carcinoma.

STUDY DESIGN

Retrospective cohort study.

SETTING

National Cancer Database.

METHODS

Patients receiving primary radiation or surgery for laryngeal squamous cell carcinoma were included from 2004 to 2017. The primary outcomes were the diagnosis-to-treatment interval (DTI) and 5-year survival. Variables of prolonged DTI (>30 days) were assessed via logistic regression models. Survival was then assessed through Cox proportional hazards models. Candidate variables for both outcomes included age, sex, race, ethnicity, distance to treatment facility, insurance coverage, treatment facility type, TNM T stage, nodal status, and DTI (in models estimating survival).

RESULTS

An overall 136,203 patients with laryngeal cancer were identified, from which 51,747 remained after exclusions were applied: 18,499 received primary surgery and 33,248 received primary radiation. Being a member of a racial or ethnic minority, advanced age, female sex, ≥30 miles from treatment facility, lack of insurance, treatment at an academic cancer center, and primary radiation were associated with a prolonged DTI. However, in spite of a faster DTI, treatment at a community cancer center was independently associated with higher mortality (hazard ratio, 1.2; P < .0001).

CONCLUSIONS

Despite being associated with prolonged DTI, receiving treatment at a high-volume academic facility was associated with significantly improved survival. Our results indicate that improved referral pathways or outreach may help improve survival in laryngeal cancer, especially in high-risk populations.

Poor treatment tolerance in head and neck cancer patients with low muscle mass

BACKGROUND

We ascertain the role of a low cervical paraspinal skeletal muscle index (CPSMI) as a biomarker for poor treatment tolerance in patients with operable mucosal head and neck squamous cell carcinoma (HNSCC).

METHODS

A prospective cohort of patients with operable HNSCC requiring microvascular reconstruction was evaluated. Low CPSMI was calculated using preoperative CT neck imaging. Poor treatment tolerance, a composite measure of incomplete therapy or severe morbidity/mortality during treatment, was the primary outcome.

RESULTS

One hundred and twenty-seven patients underwent extirpative surgery with a mean age was 60.5. Poor treatment tolerance occurred in 71 (56%) patients with 21 not completing recommended adjuvant therapy and 66 having severe treatment-related morbidity. A low CPSMI was independently associated with poor treatment tolerance (OR 2.49, 95%CI 1.10-5.93) and delay to adjuvant therapy (OR 4.48, 95%CI 1.07-27.6) after adjusting for multiple confounders.

CONCLUSION

Low CPSMI was independently associated with poor treatment tolerance in patients with operable HNSCC.

Delayed Diagnosis of Idiopathic Subglottic Stenosis

OBJECTIVE

Idiopathic subglottic stenosis (iSGS) is a rare disease, causing life-threatening dyspnea secondary to scarring. Perhaps because it is rarely encountered, there is often a delay in diagnosing iSGS. The objective of this study is to characterize diagnostic delay of iSGS, factors that prolong delay, and its impact on iSGS patients.

STUDY DESIGN

Retrospective chart review.

METHODS

A retrospective chart review of 124 iSGS patients was performed. Times of symptom onset, presentation to otolaryngologist, diagnosis, imaging, pulmonary function testing (PFTs), surgeries, emergency department (ED) visits, and hospitalizations were recorded and univariate analyses were used to identify risk factors for delay.

RESULTS

The median total time to diagnosis from symptom onset was 24.5 months, with time to first presentation of 6.3 months and healthcare delay of 17.8 months. 54.8% of patients were diagnosed with asthma. Earlier presentation to otolaryngologist was associated with shorter healthcare delay and total time to diagnosis (rho = 0.75, rho = 0.99, P < .0001). Earlier CT imaging was correlated to shorter healthcare delay (rho = 0.84, P < .0001) and total time to diagnosis (rho = 0.74, P < .001), while earlier PFTs were correlated to shorter total time to diagnosis alone (rho = 0.71, P = .01). During evaluation, 10.5% (n = 17/124) of patients had ED visits and 13.7% (n = 13/124) patients were hospitalized. Before diagnosis, 7% (9/124) of patients underwent surgeries (including 3% (n = 4) undergoing tracheostomy) and 8% (n = 10) of patients required unplanned urgent endoscopic surgery that may have been avoided with earlier diagnosis.

CONCLUSION

iSGS diagnosis is frequently delayed, resulting in additional surgeries (including tracheostomy), ED visits, and hospitalizations. Further, patients' symptoms are commonly attributed to asthma. Earlier otolaryngologist evaluation, PFTs, and CT imaging may expedite iSGS diagnosis.

Impact of Delay on Hospitalization in Older Patients With Head and Neck Cancer: A Multicenter Study

OBJECTIVE

To assess the impact of delay in treatment initiation on hospitalization, overall survival, and recurrence in older patients with head and neck cancer (HNC).

STUDY DESIGN

Retrospective multicenter study.

SETTING

Two tertiary referral centers.

METHODS

All patients with newly diagnosed HNC (≥60 years) treated between 2015 and 2017 were retrospectively included. Time-to-treatment intervals were assessed (ie, calendar days between first visit and start of treatment). Multiple multivariable models were performed with hospital admission days (>14 days), survival, and recurrence as dependent outcome variables.

RESULTS

In total, 525 patients were enrolled. The mean age was 70.7 years and 70.7% were male. Median time to treatment was 34.0 days, and 36.3% started treatment within 30 days (P = .576 between centers). Patients with radiotherapy had longer time to treatment than surgical patients (39.0 vs 29.0 days, P < .001). Current smoking status, stage IV tumors, and definitive radiotherapy were significantly associated with delay in the multivariable analysis. Time-to-treatment interval ≥30 days was a significant predictor of longer hospital admission (>14 days) in the first year after treatment in an adjusted model (odds ratio, 4.66 [95% CI, 2.59-8.37]; P < .001). Delay in treatment initiation was not associated with overall survival or tumor recurrence.

CONCLUSION

This study highlights the importance and challenges of ensuring timely treatment initiation in older patients with HNC, as treatment delay was an independent predictor of hospitalization. During oncologic workup, taking time to consider patient-centered outcomes (including minimizing time spent in hospital) while ensuring timely start of treatment requires well-structured, fast-track care pathways.

Delays in Time to Head and Neck Cancer Treatment: A South Australian Perspective

Background and Objectives: In head and neck cancer, delays in time to treatment are associated with poorer clinical outcomes. Within Australia, it is recommended that primary treatment is initiated within 56 days of initial referral. The aim of this study was to assess whether head and neck cancer treatment was delivered within these timeframe guidelines at our institution and identify factors associated with treatment delays. Methods: This retrospective cohort study assessed patients newly diagnosed with head and neck cancer over a 24 months period (2018 to 2019) at Flinders Medical Centre, Australia. Time to treatment intervals were calculated for comparison to local timeframe guidelines. Results: A total of 72 patients met the inclusion criteria. The median time from specialist referral to treatment initiation was 45.5 days (IQR 29–61), with 72% meeting the 56 days guideline. On univariate logistic regression, patients undergoing primary radiotherapy treatment were less likely to meet this guideline than those undergoing primary surgery (OR 8.8, 95% CI 2.6–28.9, p < 0.001), as were those requiring prophylactic gastrostomy tube insertion (OR 3.1, 95% CI 1.1–9.0, p < 0.05). Treatment initiation beyond 56 days had no significant impact on 12 months overall survival or disease-free survival. Conclusions: The findings of this study demonstrate that primary radiotherapy treatment is associated with delays in head and neck cancer treatment initiation, likely related to time consuming pre-treatment factors such as gastrostomy tube insertion.

Targets for improving disparate head and neck cancer outcomes in the low-income population

Low-income patients have worse head and neck cancer outcomes than those with high-income. Yet, few targets have been identified to specifically improve outcomes in the low-income population. Here, we conduct a review on the current literature on head and neck cancer outcomes in the low-income population and identify targets for intervention. The degree of disparity is in the range of 20%-90% worse overall survival in the low-income population. Eliminating smoking would have the greatest effect on head and neck cancer mortality rates in the low-income population. Additionally, access to oral cancer exams, assistance with transportation, and continued expansion of telemedicine would facilitate early diagnosis and timely treatment in patients who develop head and neck cancer.

Decision regret 3 and 6 months after treatment for head and neck cancer: An observational study of associations with clinicodemographics, anxiety, and quality of life

BACKGROUND

While quality of life (QOL), psychosocial health, and adverse treatment outcomes have been studied in head and neck cancer (HNC) patients, decision regret is an important and understudied complication that can negatively impact future health care decision making.

METHODS

Data collected using a HNC patient registry with questionnaires administered at initial consultation visits plus 3 and 6 months after treatment completion was retrospectively analyzed. A visual analog anxiety scale and the University of Washington Quality of Life were given at clinic visits. Decision regret was determined using a validated scale. Demographic and clinical variables were collected retrospectively and at baseline.

RESULTS

Patients with higher anxiety and lower self-reported QOL had higher concurrent regret at 3-month (n = 140) and at 6-month (n = 82) post-treatment. Later disease stage at presentation, nonprimary surgical treatment, and lower health literacy were associated with greater regret.

CONCLUSIONS

Decision regret was highest in HNC patients with high anxiety, low QOL, and more advanced disease.

Impact of Nonadherence to NCCN Adjuvant Radiotherapy Initiation Guidelines in Head and Neck Squamous Cell Carcinoma in an Underserved Urban Population

BACKGROUND

Nonadherence to NCCN Guidelines during time from surgery to postoperative radiotherapy (S-PORT) can alter survival outcomes in head and neck squamous cell carcinomna (HNSCC). There is a need to validate this impact in an underserved urban population and to understand risk factors and reasons for delay. We sought to investigate the impact of delayed PORT with outcomes of overall survival (OS) in HNSCC, to analyze predictive factors of delayed PORT, and to identify reasons for delay.

METHODS

We conducted a retrospective cohort study in an urban, community-based academic center. A total of 184 patients with primary HNSCC were identified through the Montefiore Medical Center cancer registry who had been treated between March 1, 2005, and March 8, 2017, and met the inclusion and exclusion criteria. The primary exposure was S-PORT. OS, recurrence, and risk factors and reasons for treatment delay were the main outcomes and measures.

RESULTS

Among 184 patients with HNSCC treated with PORT, the median S-PORT was 48.5 days (interquartile range, 41-67 days). The S-PORT threshold that optimally differentiated worse OS outcomes was >50 days (46.7% of our cohort; n=86). Independent of other relevant factors, patients with HNSCC and S-PORT >50 days had worse OS (hazard ratio, 2.30; 95% CI, 1.34-3.95) and greater recurrence (odds ratio, 3.51; 95% CI, 1.31-9.39). Predictors of delayed S-PORT included being underweight or obese, prolonged postoperative length of stay, and age >70 years. The most frequent reasons for PORT delay were complications related to surgery (22.09%), unrelated medical comorbidities (18.60%), and nonadherence/missed appointments (6.98%).

CONCLUSIONS

Delayed PORT beyond 50 days after surgery was associated with decreased OS and greater recurrence. Identification of predictive factors and reasons for treatment delay helps to target at-risk patients and facilitates interventions in underserved populations.

Role of Artificial Intelligence in the Early Diagnosis of Oral Cancer. A Scoping Review

The early diagnosis of cancer can facilitate subsequent clinical patient management. Artificial intelligence (AI) has been found to be promising for improving the diagnostic process. The aim of the present study is to increase the evidence on the application of AI to the early diagnosis of oral cancer through a scoping review. A search was performed in the PubMed, Web of Science, Embase and Google Scholar databases during the period from January 2000 to December 2020, referring to the early non-invasive diagnosis of oral cancer based on AI applied to screening. Only accessible full-text articles were considered. Thirty-six studies were included on the early detection of oral cancer based on images (photographs (optical imaging and enhancement technology) and cytology) with the application of AI models. These studies were characterized by their heterogeneous nature. Each publication involved a different algorithm with potential training data bias and few comparative data for AI interpretation. Artificial intelligence may play an important role in precisely predicting the development of oral cancer, though several methodological issues need to be addressed in parallel to the advances in AI techniques, in order to allow large-scale transfer of the latter to population-based detection protocols.

Survival analysis of patients with advanced hypopharyngeal cancer comparing patients who received primary surgery to those who received chemoradiation: An analysis of the NCDB

INTRODUCTION

The objective of this study was to use the American College of Surgeons' National Cancer Database (NCDB) to examine the association between primary treatment and overall survival (OS) among patients with locoregionally advanced hypopharyngeal cancer.

METHODS

6,055 adult patients diagnosed between 2004 and 2015 with stage III or IV, M0, hypopharyngeal squamous cell carcinoma were identified within the NCDB. Patients who received primary chemoradiation (CRT) were compared to those that received surgery with adjuvant radiation or chemoradiation (S + Adj). OS was compared between treatment groups using Kaplan-Meier analyses, propensity score adjustment, and Cox regression analyses.

RESULTS

The median survival was 22.7 months (IQR 11.0-49.0). The S + Adj group had a significantly higher comorbidity score, higher grade disease, and more advanced stage disease than the CRT group. S + Adj was associated with significantly improved survival when compared to CRT (p < 0.0001). A propensity score adjusting for facility type, facility location, care at multiple facilities, histology, and T stage was developed. S + Adj was associated with longer survival (HR: 0.72, 95% CI: 0.64-0.80) when compared to CRT in a multivariable Cox regression analysis (adjusting for age, race and ethnicity, insurance status, a comorbidity index, diagnosis year, treatment delay, N stage, and the propensity score). S + Adj was associated with significantly improved survival among those with T2 disease (p = 0.02), T3 disease (p = 0.02), and T4 disease (p < 0.0001) in sensitivity analyses examining these subcohorts independently.

CONCLUSIONS

Among patients with advanced hypopharyngeal cancer reported in NCDB, treatment with S + Adj was associated with longer survival compared to those treated with primary CRT.

Effect of socioeconomic status on survival in patients with head and neck cancer

BACKGROUND

The aim of this study was to assess the survival outcomes of head and neck cancer (HNC) by socioeconomic status.

METHODS

A national retrospective population-based cohort of HNC patients diagnosed in Israel between 2000 and 2017 was conducted. Site of residence and socioeconomic status were correlated with overall survival (OS), controlling for prognostic factors that included tumor site, stage, age, sex, and ethnic group.

RESULTS

Overall, 11 826 patients were identified. Patients from high socioeconomic areas had better overall 5-year survival than patients from low socioeconomic areas (p < 0.005). Patients in stage 3 from a high socioeconomic status had a longer median survival rate of 1.5 years than patients in the low-status group. In a cox proportional hazards analysis, we found age >65 (HR 2.91, 95% confidence interval [CI]: 2.75-3.09, p < 0.001) and low socioeconomic group (HR 1.25, 95% CI: 1.18-1.33, p < 0.001) to be correlated with inferior OS.

CONCLUSION

Our findings show that patients with HNC living in low socioeconomic areas had worse OS.

Incidental findings during the diagnostic work-up in the head and neck cancer pathway: Effects on treatment delay and survival

OBJECTIVES

As a result of the increasing number of diagnostic scans, incidental findings (IFs) are more frequently encountered during oncological work-up in patients with head and neck squamous cell carcinomas (HNSCC). IFs are unintentional discoveries found on diagnostic imaging. Relevant IFs implicate clinical consequences, resulting in delay in oncologic treatment initiation, which is associated with unfavorable outcomes. This study is the first to investigate the incidence and nature of IFs over the years and establish the effect of relevant IFs on delay.

MATERIAL AND METHODS

This retrospective study compared two time periods (2010-2011 and 2016-2017), described associations between relevant IFs and delay in carepathway interval (days between first visit and treatment initiation) and assessed the effect of relevant IFs on overall two-year survival.

RESULTS

In total, 592 patients were included. At least one IF was found in 61.5% of the patients, most frequently on chest-CT. In 128 patients (21.6%) a relevant IF was identified, resulting for the majority in radiologist recommendations (e.g. additional scanning). Presence of a relevant IF was an independent significant factor associated with delay in treatment initiation. The risk of dying was higher for patients with a relevant IF, although not significant in the multivariable model (HR: 1.46, p = 0.079).

CONCLUSION

In diagnostic work-up for HNSCC patients, relevant IFs are frequently encountered. As the frequency of additional imaging rises over the years, the number of IFs increased simultaneously. These relevant IFs yield clinical implications and this study described that relevant IFs result in significant delay in treatment initiation.
