Higher Rates of Inadequate Adjuvant Radiation Dose Among Older Adults with Head and Neck Cancer

OBJECTIVE

To determine the rate of inadequate radiotherapy and identify risk factors associated with inadequate adjuvant radiotherapy for head and neck cancer among older adults.

METHODS

A retrospective review of the National Cancer Database (NCDB) was performed to identify patients diagnosed with squamous cell cancer of the head and neck between 2004 and 2017. Patients with a single malignancy, negative surgical margins, no extranodal extension, and receipt of adjuvant radiation without systemic therapy were included in the study cohort. The main outcome of interest was the adjuvant radiation dose received. Participant data were compared using univariable, multivariable, and correlation analyses to evaluate risk factors for inadequate radiation therapy (RT) dosing.

RESULTS

Among 7608 patients, 1010 patients (13.3%) received an inadequate radiation dose and 6598 (86.7%) received an adequate dose. Patients living in a higher income zip-code, younger age, and those who received intensity-modulated RT (IMRT) were more likely to receive an adequate radiation dose (p < 0.05). Patients older than 70 and 80 years old had a greater likelihood of receiving an inadequate radiation dose (≥70 vs. <70: 16.9% vs. 12.5%; p < 0.05 and ≥80 vs. <80: 20.6% vs. 13.0%%; p < 0.05). Similarly, increasing age was negatively correlated with radiation dose (correlation coefficient: -0.05; p < 0.001).

CONCLUSION

A substantial proportion of older patients receiving adjuvant radiation do not complete the full treatment. Older age, year of diagnosis, non-IMRT, and living in a lower-income zip code were associated with early termination of RT. Future studies should examine strategies to improve tolerance of adjuvant RT so that more patients complete the full treatment.

Organization of head and neck cancer rehabilitation care: a national survey among healthcare professionals in Dutch head and neck cancer centers

PURPOSE

Head and neck cancer (HNC) treatment often leads to physical and psychosocial impairments. Rehabilitation can overcome these limitations and improve quality of life. The aim of this study is to obtain an overview of rehabilitation care for HNC, and to investigate factors influencing rehabilitation provision, in Dutch HNC centers, and to some extent compare it to other countries.

METHODS

An online survey, covering five themes: organizational structure; rehabilitation interventions; financing; barriers and facilitators; satisfaction and future improvements, among HNC healthcare- and financial professionals of Dutch HNC centers.

RESULTS

Most centers (86%) applied some type of rehabilitation care, with variations in organizational structure. A speech language therapist, physiotherapist and dietitian were available in all centers, but other rehabilitation healthcare professionals in less than 60%. Facilitators for providing rehabilitation services included availability of a contact person, and positive attitude, motivation, and expertise of healthcare professionals. Barriers were lack of reimbursement, and patient related barriers including comorbidity, travel (time), low health literacy, limited financial capacity, and poor motivation.

CONCLUSION

Although all HNC centers included offer rehabilitation services, there is substantial practice variation, both nationally and internationally. Factors influencing rehabilitation are related to the motivation and expertise of the treatment team, but also to reimbursement aspects and patient related factors. More research is needed to investigate the extent to which practice variation impacts individual patient outcomes and how to integrate HNC rehabilitation into routine clinical pathways.

Factors associated with oral hygiene compliance in patients treated with radiation therapy for head and neck cancer

BACKGROUND

Patients who are oral hygiene noncompliant (OHNC) are more likely to lose teeth after radiation therapy (RT) for head and neck cancer (HNC), which increases the risk of developing osteoradionecrosis. A previous study revealed that patients who were OHNC at baseline (BL) who became oral hygiene compliant during follow-up had the best tooth-failure outcomes. The purpose of this study was to identify factors associated with oral hygiene compliance (OHC), overall, and among those who were BL OHNC.

METHODS

This was an observational, prospective, cohort study of 518 patients with HNC assessed before RT and at post-RT follow-up visits every 6 months for 2 years. Patient and treatment-related information was collected at BL and during follow-up, including self-reported OHC. OHC was defined as toothbrushing at least twice daily and flossing at least once daily.

RESULTS

Of the 296 patients who self-reported being BL OHNC, 44 (14.9%) became oral hygiene compliant at all follow-up visits. Among this group, those who had dental insurance (P = .026), surgery before RT (P = .008), limited mouth opening before RT (P = .001), compliant fluoride use (P = .023), primary RT site of oral cavity (P = .004), and primary surgical site of larynx and hypopharynx (P = .042) were more likely to become oral hygiene compliant post-RT.

CONCLUSIONS

The reasons for the cohort of patients with HNC in this study being OHNC are multifaceted and relate to socioeconomic factors and cancer characteristics.

PRACTICAL IMPLICATIONS

Finding ways to increase OHC and fluoride use among patients with HNC who are at greatest risk of being OHNC should be explored.

Measuring financial toxicity in head and neck cancer: a systematic review

Objective

The current study systematically reviews the literature about financial toxicity (FT) in head and neck cancer patients. Three databases were reviewed: PubMed, Scopus and Web of Science.

Methods

Full text English papers published from 2000 to 2022 reporting on quantitative results about FT in head and neck cancer survivors collected through structured questionnaires or interviews were included.

Results

Twenty-seven articles were included. Most of the articles were published after 2015 and from United States. There was a slight prevalence of papers dealing with oropharyngeal cancer, squamous-cell carcinoma and locally advanced head and neck cancer. Measures of FT were obtained through validated questionnaires like COST, FIT and FDQ. Collected data were mostly referrable to financial spending, financial resources, psychosocial aspect, support seeking, coping care and coping lifestyle subdomain. FT scores by COST were found to be worse in the COVID era. Financial counseling and adequate information about the costs of treatment were two effective strategies to mitigate FT.

Conclusions

FT is a relatively new challenge in head and neck cancer treatment, whose expenses are higher than therapies for other cancers. A universal method to assess FT and a unified guideline for the administration of questionnaires are needed to mitigate FT and to improve patient outcomes.

Mendelian randomization eradicates the causal relationship between educational attainment, household income, and oropharyngeal cancer

Background

It was reported that educational attainment and household income are associated with oropharyngeal cancer. However, whether such an association is causal is still unknown.

Methods

The Mendelian randomization (MR) design was performed to disentangle their causal relationship. Initially, genetic variants proxied for educational attainment and household income were extracted from the largest genome-wide association studies (GWAS), and two oropharyngeal GWAS datasets were used in the discovery and validation stages separately. A reverse MR analysis was carried out to judge whether oropharyngeal cancer affects educational attainment and household income. The results from the two stages were combined using meta-analysis. The heterogeneity and horizontal pleiotropy were appraised using several methods.

Results

All selected genetic variants were valid. In the discovery stage, genetically elevated years of education might decrease the risk of oropharyngeal cancer (IVW OR = 0.148 [0.025, 0.872], p-value = 0.035), while such a result became insignificant in the validation stage (IVW p-value >0.05). Household income cannot change the risk of oropharyngeal cancer at both stages. The reverse MR suggested that oropharyngeal cancer should slightly alter household income (IVW OR = 1.001 [1.000, 1.003], p-value = 0.036) in the discovery set, but the result cannot be replicated in the validation stage. The meta-analysis did not find any significant results either. The results were also assessed by sensitivity analyses, and there was no heterogeneity or horizontal pleiotropy in the analyses. The statistical powers were all above 80% at the discovery stage.

Conclusions

There should be no causal association between educational attainment, household income, and oropharyngeal cancer.
