Social determinants of health and treatment decisions in head and neck cancer

Readability of Patient Education Materials in Head and Neck Cancer: A Systematic Review

Importance

Patient education materials (PEMs) can promote patient engagement, satisfaction, and treatment adherence. The American Medical Association recommends that PEMs be developed for a sixth-grade or lower reading level. Health literacy (HL) refers to an individual's ability to seek, understand, and use health information to make appropriate decisions regarding their health. Patients with suboptimal HL may not be able to understand or act on health information and are at risk for adverse health outcomes.

Objective

To assess the readability of PEMs on head and neck cancer (HNC) and to evaluate HL among patients with HNC.

Evidence Review

A systematic review of the literature was performed by searching Cochrane, PubMed, and Scopus for peer-reviewed studies published from 1995 to 2024 using the keywords head and neck cancer, readability, health literacy, and related synonyms. Full-text studies in English that evaluated readability and/or HL measures were included. Readability assessments included the Flesch-Kincaid Grade Level (FKGL grade, 0-20, with higher grades indicating greater reading difficulty) and Flesch Reading Ease (FRE score, 1-100, with higher scores indicating easier readability), among others. Reviews, conference materials, opinion letters, and guidelines were excluded. Study quality was assessed using the Appraisal Tool for Cross-Sectional Studies.

Findings

Of the 3235 studies identified, 17 studies assessing the readability of 1124 HNC PEMs produced by professional societies, hospitals, and others were included. The mean FKGL grade ranged from 8.8 to 14.8; none of the studies reported a mean FKGL of grade 6 or lower. Eight studies assessed HL and found inadequate HL prevalence ranging from 11.9% to 47.0%.

Conclusions and Relevance

These findings indicate that more than one-third of patients with HNC demonstrate inadequate HL, yet none of the PEMs assessed were developed for a sixth grade or lower reading level, as recommended by the American Medical Association. This incongruence highlights the need to address the readability of HNC PEMs to improve patient understanding of the disease and to mitigate potential barriers to shared decision-making for patients with HNC. It is crucial to acknowledge the responsibility of health care professionals to produce and promote more effective PEMs to dismantle the potentially preventable literacy barriers.

Expanding the role of combined immunochemotherapy and immunoradiotherapy in the management of head and neck cancer (Review)

Immunotherapy has become one of the most promising approaches in tumor therapy, and there are numerous associated clinical trials in China. As an immunosuppressive tumor, head and neck squamous cell carcinoma (HNSCC) carries a high mutation burden, making immune checkpoint inhibitors promising candidates in this field due to their unique mechanism of action. The present review outlines a comprehensive multidisciplinary cancer treatment approach and elaborates on how combining immunochemotherapy and immunoradiotherapy guidelines could enhance clinical efficacy in patients with HNSCC. Furthermore, the present review explores the immunology of HNSCC, current immunotherapeutic strategies to enhance antitumor activity, ongoing clinical trials and the future direction of the current immune landscape in HNSCC. Advanced-stage HNSCC presents with a poor prognosis, low survival rates and minimal improvement in patient survival trends over time. Understanding the potential of immunotherapy and ways to combine it with surgery, chemotherapy and radiotherapy confers good prospects for the management of human papillomavirus (HPV)-positive HNSCC, as well as other HPV-positive malignancies. Understanding the immune system and its effect on HNSCC progression and metastasis will help to uncover novel biomarkers for the selection of patients and to enhance the efficacy of treatments. Further research on why current immune checkpoint inhibitors and targeted drugs are only effective for some patients in the clinic is needed; therefore, further research is required to improve the overall survival of affected patients.

Limited English proficiency and head and neck cancer outcomes

PURPOSE

Limited English proficiency (LEP) is common among hospitalized patients and may impact clinical care and outcomes. This study aimed to examine the relationship between LEP and clinical oncological outcomes for patients with head and neck cancer (HNC).

MATERIALS AND METHODS

A single center retrospective review was conducted including adult patients with squamous cell carcinoma of the head and neck who received treatment with curative intent between January 1, 2014 and July 1, 2019. Clinical data collected included patient demographics and clinical variables. Univariate and multivariate analysis was performed to determine whether there was an association between LEP and demographic and clinical factors.

RESULTS

There were 477 patients included in the study; 426 (81%) were English proficient (EP) while 51 (10.7%) were LEP. The LEP patients were diagnosed with cancer at a later overall stage (p = 0.03) and less frequently treated with surgery alone compared to English speaking patients (p < 0.001). After adjusting for overall stage and primary site, LEP patients were significantly more likely to receive primary surgical management compared to primary non-surgical management [OR = 2.29 95% CI (0.93, 5.58), p = 0.008]. There was also a significant association between LEP and primary site of tumor (p < 0.01). Kaplan-Meyer curves for overall survival and disease specific survival showed no significant differences between the two cohorts (p = 0.8063 and p = 0.4986, respectively).

CONCLUSIONS

LEP may impact access to care resulting in more advanced overall tumor stage at presentation and treatment with primary surgery compared to non-surgical management after adjusting for tumor stage and primary site. Interventions to provide better access to care, awareness of HNC in the LEP populations, and earlier detection may improve outcomes for LEP patients.
