Health-related quality of life differences between African Americans and non-Hispanic whites with head and neck cancer

"I won't be able to speak for three days after": Ethical and practical considerations in qualitative research involving people with a laryngectomy

Purpose: A laryngectomy impacts communication, swallowing and breathing. It is disfiguring and can disrupt quality of life, one's sense of identity, and relationships. It can increase dependence on others, trigger social stigma, avoidant coping and suicidal risk. Qualitative research has the potential to enable greater understanding of these consequences. However, almost nothing has been written about the specific ethical issues that can arise when carrying out research with people with laryngectomy (PWL). This paper builds on the experiences of the authors in the field and seeks to examine and explain these research ethics considerations and how they impact research design, data collection, data analysis and dissemination.Method: Using a framework based on the values underpinning the Australian National Statement on Ethical Conduct in Human Research, respect, merit and integrity, justice and beneficence, we have highlighted key issues relevant to this particular population.Main contribution: Different practical approaches are provided to address the ethical concerns that arise when conducting research with PWL. These include access to participants and ensuring diverse representation; balancing harm and benefit; achieving accurate interpretation, analysis and representation of the data generated through the research; research as a partnership that is respectful, empowering and fosters collaboration.Conclusion: This paper breaks new ground in discussing the ethical considerations and practical challenges relevant to researching the experiences of PWL.

A Systematic Review of Head and Neck Cancer Health Disparities: A Call for Innovative Research

OBJECTIVE

(1) Describe the existing head and neck cancer health disparities literature. (2) Contextualize these studies by using the NIMHD research framework (National Institute on Minority Health and Health Disparities). (3) Explore innovative ideas for further study and intervention.

DATA SOURCES

Ovid MEDLINE, Embase, Web of Science, and Google Scholar.

REVIEW METHODS

Databases were systematically searched from inception to April 20, 2020. The PRISMA checklist was followed (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Two authors reviewed all articles for inclusion. Extracted data included health disparity population and outcomes, study details, and main findings and recommendations. Articles were also classified per the NIMHD research framework.

RESULTS

There were 148 articles included for final review. The majority (n = 104) focused on health disparities related to at least race/ethnicity. Greater than two-thirds of studies (n = 105) identified health disparities specific to health behaviors or clinical outcomes. Interaction between the individual domain of influence and the health system level of influence was most discussed (n = 99, 66.9%). Less than half of studies (n = 61) offered specific recommendations or interventions.

CONCLUSIONS

There has been extensive study of health disparities for head and neck cancer, largely focusing on individual patient factors or health care access and quality. This review identifies gaps in this research, with large numbers of retrospective database studies and little discussion of potential contributors and explanations for these disparities. We recommend shifting research on disparities upstream toward a focus on community and societal factors, rather than individual, and an evaluation of interventions to promote health equity.

Understanding Underuse of Advance Care Planning Among a Cohort of African American Patients With Advanced Cancer: Formative Research That Examines Gaps in Intent to Discuss Options for Care

BACKGROUND

Advance care planning (ACP), palliative care (PC), and hospice are often underutilized by African Americans (AAs). This study assessed the impact of stage of intent to discuss ACP options as key potential barriers.

METHODS

We examined intent to discuss completion of ACP, PC, and hospice among 22 AA patients with cancer admitted to a local safety net hospital. Participants were asked about intent to discuss an advanced directive or living will (AD/LW), medical power of attorney (MPOA), PC, and hospice with their doctors. Intent to discuss these ACP components was based on the transtheoretical model. Electronic health records were reviewed at various intervals to assess completion of ACP behaviors and survival.

RESULTS

Participants had colorectal (33%), breast (44%), and lung (23%) cancer, and 82% had stage III/IV disease. Low percentages of patients were in the precontemplation stage for AD/LW completion (4.6%), MPOA completion (13.6%), and PC discussions (27.2%), but 77.2% were in the precontemplation stage for hospice discussions. At 1 year, only 5% completed an AD/LW, 36.4% appointed an MPOA, 42.9% were referred to PC, and 12.5% were referred to hospice. More than half (54.6%) were deceased by the study's conclusion. Most (81%) of these died within 6 months of their baseline study assessment.

CONCLUSIONS

Despite being hospitalized with advanced cancer and having poor prognosis, intent to discuss ACP options, PC, and hospice in this population was variable, and completion of these activities was low. This formative research is needed to develop education and counseling interventions for this high-risk, vulnerable population.

Immunometabolic Alterations by HPV Infection: New Dimensions to Head and Neck Cancer Disparity

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer, with high morbidity and mortality. Racial disparity in HNSCC is observed between African Americans (AAs) and whites, effecting both overall and 5-year survival, with worse prognosis for AAs. In addition to socio-economic status and demographic factors, many epidemiological studies have also identified factors including coexisting human papillomavirus (HPV) infection, primary tumor location, and a variety of somatic mutations that contribute to the prognostic incongruities in HNSCC patients among AAs and whites. Recent research also suggests HPV-induced dysregulation of tumor metabolism and immune microenvironment as the major regulators of HNSCC patient prognosis. Outcomes of several preclinical and clinical studies on targeted therapeutics warrant the need to elucidate the inherent mechanistic and population-based disparities underlying patient responses. This review systematically reports the underlying reasons for inconsistency in disease prognosis and therapy responses among HNSCC patients from different racial populations. The focus of this review is twofold: aside from discussing the causes of racial disparity, we also seek to identify the consequences of such disparity in terms of HPV infection and its associated mutational, metabolic, and immune landscapes. Considering the clinical impact of differential patient outcomes among AA and white populations, understanding the underlying cause of this disparity may pave the way for novel precision therapy for HNSCC.

Effects of income and residential area on survival of patients with head and neck cancers following radiotherapy: working age individuals in Taiwan

Objectives

The five-year survival rate of head and neck cancer (HNC) after radiotherapy (RT) varies widely from 35% to 89%. Many studies have addressed the effect of socioeconomic status and urban dwelling on the survival of HNC, but a limited number of studies have focused on the survival rate of HNC patients after RT.

Materials and methods

During the period of 2000–2013, 40,985 working age individuals (20 < age < 65 years) with HNC patients treated with RT were included in this study from a registry of patients with catastrophic illnesses maintained by the Taiwan National Health Insurance Research Database (NHIRD).

Results

The cumulative survival rate of HNC following RT in Taiwan was 53.2% (mean follow-up period, 3.75 ± 3.31 years). The combined effects of income and geographic effect on cumulative survival rates were as follows: high income group > medium income group > low income group and northern > central > southern > eastern Taiwan. Patients with moderate income levels had a 36.9% higher risk of mortality as compared with patients with high income levels (hazard ratio (HR) = 1.369; p < 0.001). Patients with low income levels had a 51.4% greater risk of mortality than patients with high income levels (HR = 1.514, p < 0.001).

Conclusion

In Taiwan, income and residential area significantly affected the survival rate of HNC patients receiving RT. The highest income level group had the best survival rate, regardless of the geographic area. The difference in survival between the low and high income groups was still pronounced in more deprived areas.

Health-related quality of life and psychological distress among cancer survivors in a middle-income country

OBJECTIVES

Quality of life and psychological well-being are important patient-centered outcomes, which are useful in evaluation of cancer care delivery. However, evidence from low-income and middle-income countries remains scarce. We assessed health-related quality of life (HRQoL) and prevalence of psychological distress (anxiety or depression), as well as their predictors, among cancer survivors in a middle-income setting.

METHODS

Through the Association of Southeast Asian Nations Costs in Oncology study, 1490 newly diagnosed cancer patients were followed-up in Malaysia for 1 year. Health-related quality of life was assessed by using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and EuroQol-5 (EQ-5D) dimension questionnaires at baseline, 3 and 12 months. Psychological distress was assessed by using Hospital Anxiety and Depression Scale. Data were modeled by using general linear and logistic regressions analyses.

RESULTS

One year after diagnosis, the mean EORTC QLQ-C30 Global Health score of the cancer survivors remained low at 53.0 over 100 (SD 21.4). Fifty-four percent of survivors reported at least moderate levels of anxiety, while 27% had at least moderate levels of depression. Late stage at diagnosis was the strongest predictor of low HRQoL. Increasing age, being married, high-income status, hospital type, presence of comorbidities, and chemotherapy administration were also associated with worse HRQoL. The significant predictors of psychological distress were cancer stage and hospital type.

CONCLUSION

Cancer survivors in this middle-income setting have persistently impaired HRQoL and high levels of psychological distress. Development of a holistic cancer survivorship program addressing wider aspects of well-being is urgently needed in our settings.

Exploratory Factor Analysis of NRG Oncology's University of Washington Quality of Life Questionnaire-RTOG Modification

CONTEXT

The 15-item University of Washington Quality of Life questionnaire-Radiation Therapy Oncology Group (RTOG) modification (UW-QOL-RTOG modification) has been used in several trials of head and neck cancer conducted by NRG Oncology such as RTOG 9709, RTOG 9901, RTOG 0244, and RTOG 0537.

OBJECTIVES

This study is an exploratory factor analysis (EFA) to establish validity and reliability of the instrument subscales.

METHODS

EFA on the UW-QOL-RTOG modification was conducted using baseline data from NRG Oncology's RTOG 0537, a trial of acupuncture-like transcutaneous electrical nerve stimulation in treating radiation-induced xerostomia. Cronbach α coefficient was calculated to measure reliability; correlation with the University of Michigan Xerostomia Related Quality of Life Scale was used to evaluate concurrent validity; and correlations between consecutive time points were used to assess test-retest reliability.

RESULTS

The 15-item EFA of the modified tool resulted in 11 items split into four factors: mucus, eating, pain, and activities. Cronbach α ranged from 0.71 to 0.93 for the factors and total score, consisting of all 11 items. There were strong correlations (ρ ≥ 0.60) between consecutive time points and between total score and the Xerostomia Related Quality of Life Scale total score (ρ > 0.65).

CONCLUSION

The UW-QOL-RTOG modification is a valid tool that can be used to assess symptom burden of head and neck cancer patients receiving radiation therapy or those who have recently completed radiation. The modified tool has acceptable reliability, concurrent validity, and test-retest reliability in this patient population, as well as the advantage of having being shortened from 15 to 11 items.

Factors that impact health-related quality of life over time for individuals with head and neck cancer

OBJECTIVES/HYPOTHESIS

To identify sociodemographic, behavioral, and clinical factors associated with health-related quality of life (HRQOL) for head and neck cancer (HNC) patients over time.

STUDY DESIGN

A population-based longitudinal cohort study.

METHODS

Newly diagnosed HNC patients (N = 587) were administered the Functional Assessment of Cancer Therapy-Head and Neck questionnaire at baseline (median 3 months postdiagnosis) and two follow-up assessments (median 22 and 42 months). Linear mixed-effect models were used with backward variable selection to identify factors associated with HRQOL over time (P < .05). Adjusted means reported at 2 years postdiagnosis.

RESULTS

African Americans reported better Functional Well-Being than whites (mean of 20.01 vs. 18.53) and fewer HNC symptoms over time. Older patients (75+ years) reported better HRQOL than younger patients (< 50 years). Current tobacco use compared to no tobacco use had worse Physical (20.20 vs. 21.50), Emotional (17.55 vs. 19.06), Social (21.28 vs. 22.88), and Functional (17.32 vs. 19.29) Well-Being and more HNC symptoms (21.50 vs. 23.71). Radiation therapy was associated with worse Physical and Functional Well-Being and more head and neck symptoms over time, but HRQOL was similar to those who were not irradiated by 2 to 4 years postdiagnosis.

CONCLUSION

This study identified key factors for individuals at risk for poorer HRQOL that may help clinicians and caregivers find solutions to address these decrements. Smoking cessation programs can be encouraged for survivors who use tobacco. Psychological and social support and medications may help for dealing with emotional distress and dealing with the physical symptoms from treatment.
