Functional outcomes and rehabilitation strategies in patients treated with chemoradiotherapy for advanced head and neck cancer: a systematic review

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.

Prevalence of obstructive sleep apnea after treatment for advanced T-stage head and neck cancer

PURPOSE

Treatment of head and neck cancer (HNC) may lead to obstructive sleep apnea (OSA), but conclusive results on the prevalence of OSA are lacking. The objective of this study is to investigate the prevalence of OSA in a cohort of patients treated for advanced T-stage HNC.

METHODS

A cross-sectional study was conducted in two tertiary cancer care centers including patients at least 1 year after treatment with curative intent with surgery and/or (chemo)radiotherapy ((C)RT) for advanced T-staged (T3-4) cancer of the oral cavity, oropharynx, hypopharynx, or larynx. A polysomnography (PSG) was performed in all participants. OSA was defined as an apnea-hypopnea index (AHI) of 15 events/h or higher or an AHI of 5 events/h and higher with OSA related symptoms, such as sleeping problems, daytime dysfunction and/or cardiac/metabolic comorbidities collected through file review and questionnaires.

RESULTS

Of the 67 participants, 48 (72%, 95% CI 59-82%) were diagnosed with OSA. Possible risk factors are male gender, higher BMI, greater neck circumference, more nicotine pack years, cardiometabolic comorbidities, use of medication with sleepiness as side effect, present tonsils, lower T-stage (T3 vs. T4 stage), higher AJCC stage and a HPV-negative tumor.

CONCLUSION

In this population of advanced T-stage HNC patients, the prevalence of OSA was 72%, which is considerably higher than in the general population (2-50%). Given the high prevalence, screening of this entire subgroup for OSA may be indicated. Future studies to identify high risk factors and develop an OSA screening protocol are needed.

Machine learning in the evaluation of voice and swallowing in the head and neck cancer patient

PURPOSE OF REVIEW

The purpose of this review is to present recent advances and limitations in machine learning applied to the evaluation of speech, voice, and swallowing in head and neck cancer.

RECENT FINDINGS

Novel machine learning models incorporating diverse data modalities with improved discriminatory capabilities have been developed for predicting toxicities following head and neck cancer therapy, including dysphagia, dysphonia, xerostomia, and weight loss as well as guiding treatment planning. Machine learning has been applied to the care of posttreatment voice and swallowing dysfunction by offering objective and standardized assessments and aiding innovative technologies for functional restoration. Voice and speech are also being utilized in machine learning algorithms to screen laryngeal cancer.

SUMMARY

Machine learning has the potential to help optimize, assess, predict, and rehabilitate voice and swallowing function in head and neck cancer patients as well as aid in cancer screening. However, existing studies are limited by the lack of sufficient external validation and generalizability, insufficient transparency and reproducibility, and no clear superior predictive modeling strategies. Algorithms and applications will need to be trained on large multiinstitutional data sets, incorporate sociodemographic data to reduce bias, and achieve validation through clinical trials for optimal performance and utility.

Exploring the use of rehabilitation in individuals with head and neck cancer undergoing treatment: a scoping review

Explore the use, characteristics, feasibility, and functional outcomes of rehabilitation interventions used for individuals with head and neck cancer (HNC) during treatment.

Searches were conducted in four databases from Jan 2011 to Dec 31, 2022. Included studies had to include adults with HNC undergoing treatment, a rehabilitation intervention, an assessment of functional outcome(s) addressed by the International Classification of Functioning Framework (ICF) and be published in English language. Title and abstract screening, full-text review, and data extraction were completed independently, in duplicate. Descriptive statistics and a qualitative synthesis summarized findings.

Twenty-seven studies were included in this review. The majority of studies were randomized controlled trials (70%). Most individuals represented in the included studies were males (92% of all participants) between 50 and 60 years of age. Interventions led by a speech language pathologist (33%) were most commonly described. Sixteen studies (59%) described primary outcomes that fit the ICF "impairment" domain.

We identified few studies that explored the use, feasibility, and effectiveness of rehabilitation interventions for individuals with HNC during treatment. Future research should assess the effectiveness of rehabilitation interventions on functional outcomes beyond the ICF body function and structure domain.

Non-medical interventions to enhance return to work for people with cancer

BACKGROUND

People with cancer are 1.4 times more likely to be unemployed than people without a cancer diagnosis. Therefore, it is important to investigate whether programmes to enhance the return-to-work (RTW) process for people who have been diagnosed with cancer are effective. This is an update of a Cochrane review first published in 2011 and updated in 2015.

OBJECTIVES

To evaluate the effectiveness of non-medical interventions aimed at enhancing return to work (RTW) in people with cancer compared to alternative programmes including usual care or no intervention.

SEARCH METHODS

We searched CENTRAL (the Cochrane Library), MEDLINE, Embase, CINAHL, PsycINFO and three trial registers up to 18 August 2021. We also examined the reference lists of included studies and selected reviews, and contacted authors of relevant studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and cluster-RCTs on the effectiveness of psycho-educational, vocational, physical or multidisciplinary interventions enhancing RTW in people with cancer. The primary outcome was RTW measured as either RTW rate or sick leave duration measured at 12 months' follow-up. The secondary outcome was quality of life (QoL).

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed RCTs for inclusion, extracted data and rated certainty of the evidence using GRADE. We pooled study results judged to be clinically homogeneous in different comparisons reporting risk ratios (RRs) with 95% confidence intervals (CIs) for RTW and mean differences (MD) or standardised mean differences (SMD) with 95% CIs for QoL.

MAIN RESULTS

We included 15 RCTs involving 1477 people with cancer with 19 evaluations because of multiple treatment groups. In this update, we added eight new RCTs and excluded seven RCTs from the previous versions of this review that were aimed at medical interventions. All included RCTs were conducted in high-income countries, and most were aimed at people with breast cancer (nine RCTs) or prostate cancer (two RCTs). Risk of bias We judged nine RCTs at low risk of bias and six at high risk of bias. The most common type of bias was a lack of blinding (9/15 RCTs). Psycho-educational interventions We found four RCTs comparing psycho-educational interventions including patient education and patient counselling versus care as usual. Psycho-educational interventions probably result in little to no difference in RTW compared to care as usual (RR 1.09, 95% CI 0.96 to 1.24; 4 RCTs, 512 participants; moderate-certainty evidence). This means that in the intervention and control groups, approximately 625 per 1000 participants may have returned to work. The psycho-educational interventions may result in little to no difference in QoL compared to care as usual (MD 1.47, 95% CI -2.38 to 5.32; 1 RCT, 124 participants; low-certainty evidence). Vocational interventions We found one RCT comparing vocational intervention versus care as usual. The evidence was very uncertain about the effect of a vocational intervention on RTW compared to care as usual (RR 0.94, 95% CI 0.78 to 1.13; 1 RCT, 34 participants; very low-certainty evidence). The study did not report QoL. Physical interventions Four RCTs compared a physical intervention programme versus care as usual. These physical intervention programmes included walking, yoga or physical exercise. Physical interventions likely increase RTW compared to care as usual (RR 1.23, 95% CI 1.08 to 1.39; 4 RCTs, 434 participants; moderate-certainty evidence). This means that in the intervention group probably 677 to 871 per 1000 participants RTW compared to 627 per 1000 in the control group (thus, 50 to 244 participants more RTW). Physical interventions may result in little to no difference in QoL compared to care as usual (SMD -0.01, 95% CI -0.33 to 0.32; 1 RCT, 173 participants; low-certainty evidence). The SMD translates back to a 1.8-point difference (95% CI -7.54 to 3.97) on the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire Core 30 (EORTC QLQ-C30). Multidisciplinary interventions Six RCTs compared multidisciplinary interventions (vocational counselling, patient education, patient counselling, physical exercises) to care as usual. Multidisciplinary interventions likely increase RTW compared to care as usual (RR 1.23, 95% CI 1.09 to 1.33; 6 RCTs, 497 participants; moderate-certainty evidence). This means that in the intervention group probably 694 to 844 per 1000 participants RTW compared to 625 per 1000 in the control group (thus, 69 to 217 participants more RTW). Multidisciplinary interventions may result in little to no difference in QoL compared to care as usual (SMD 0.07, 95% CI -0.14 to 0.28; 3 RCTs, 378 participants; low-certainty evidence). The SMD translates back to a 1.4-point difference (95% CI -2.58 to 5.36) on the EORTC QLQ-C30.

AUTHORS' CONCLUSIONS

Physical interventions (four RCTs) and multidisciplinary interventions (six RCTs) likely increase RTW of people with cancer. Psycho-educational interventions (four RCTs) probably result in little to no difference in RTW, while the evidence from vocational interventions (one RCT) is very uncertain. Psycho-educational, physical or multidisciplinary interventions may result in little to no difference in QoL. Future research on enhancing RTW in people with cancer involving multidisciplinary interventions encompassing a physical, psycho-educational and vocational component is needed, and be preferably tailored to the needs of the patient.

Development and Evaluation of the Psychometric Properties of the Tamil Version of Eating Assessment Tool - 10 (EAT-10): Preliminary Findings from Persons with Head and Neck Cancer

Aims: This study aimed to develop and evaluate the psychometric properties of the Tamil version of the Eating Assessment Tool (EAT-10). Setting & Study Design: Prospective cross-sectional study on persons with Head and Neck Cancer (HNC) during their follow-up for oncological and swallowing consultation at a tertiary care hospital and healthy individuals recruited from the community. Methods: The study was conducted in two phases: (1) translation and development of the Tamil version of EAT-10 and (2) administration of Tamil EAT-10 to assess internal consistency reliability, test-retest reliability and known-group validity. 92 participants with HNC in the clinical group and 149 healthy adults in the control group completed the Tamil EAT-10. In addition, a subgroup of 20 participants with HNC repeated the questionnaire within a week to assess test-retest reliability. Results: The Cronbach alpha for the 10 items was 0.96 indicating high internal consistency reliability. The test-retest reliability of the individual items and the total scores (r = 0.98) of the Tamil version of EAT-10 were high. The total EAT-10 scores for the HNC group (14.4 ± 11.5) were significantly higher (p < 0.001) than the scores for healthy adults (0.72 ± 2.0). Conclusion: The Tamil version of the EAT-10 developed in this study is a reliable and valid self-administered tool for identifying concerns related to swallowing among persons treated for HNC and healthy adults. This tool can be implemented for clinical practice and research in dysphagia among a Tamil-speaking population.

Expert Consensus Statement: Management of Dysphagia in Head and Neck Cancer Patients

OBJECTIVE

To develop an expert consensus statement (ECS) on the management of dysphagia in head and neck cancer (HNC) patients to address controversies and offer opportunities for quality improvement. Dysphagia in HNC was defined as swallowing impairment in patients with cancers of the nasal cavity, paranasal sinuses, nasopharynx, oral cavity, oropharynx, larynx, or hypopharynx.

METHODS

Development group members with expertise in dysphagia followed established guidelines for developing ECS. A professional search strategist systematically reviewed the literature, and the best available evidence was used to compose consensus statements targeted at providers managing dysphagia in adult HNC populations. The development group prioritized topics where there was significant practice variation and topics that would improve the quality of HNC patient care if consensus were possible.

RESULTS

The development group identified 60 candidate consensus statements, based on 75 initial proposed topics and questions, that focused on addressing the following high yield topics: (1) risk factors, (2) screening, (3) evaluation, (4) prevention, (5) interventions, and (6) surveillance. After 2 iterations of the Delphi survey and the removal of duplicative statements, 48 statements met the standardized definition for consensus; 12 statements were designated as no consensus.

CONCLUSION

Expert consensus was achieved for 48 statements pertaining to risk factors, screening, evaluation, prevention, intervention, and surveillance for dysphagia in HNC patients. Clinicians can use these statements to improve quality of care, inform policy and protocols, and appreciate areas where there is no consensus. Future research, ideally randomized controlled trials, is warranted to address additional controversies related to dysphagia in HNC patients.

The Change in Social Eating over Time in People with Head and Neck Cancer Treated with Primary (Chemo)Radiotherapy: The Role of Swallowing, Oral Function, and Nutritional Status

This study aimed at investigating the change in social eating problems from diagnosis to 24 months after primary (chemo)radiotherapy and its associations with swallowing, oral function, and nutritional status, in addition to the clinical, personal, physical, psychological, social, and lifestyle dimensions. Adult patients from the NETherlands QUality of life and BIomedical Cohort (NET-QUBIC) treated with curative intent with primary (chemo)radiotherapy for newly-diagnosed HNC and who provided baseline social eating data were included. Social eating problems were measured at baseline and at 3-, 6-, 12-, and 24-month follow-up, with hypothesized associated variables at baseline and at 6 months. Associations were analyzed through linear mixed models. Included patients were 361 (male: 281 (77.8%), age: mean = 63.3, SD = 8.6). Social eating problems increased at the 3-month follow-up and decreased up to 24 months (F = 33.134, p < 0.001). The baseline-to-24 month change in social eating problems was associated with baseline swallowing-related quality of life (F = 9.906, p < 0.001) and symptoms (F = 4.173, p = 0.002), nutritional status (F = 4.692, p = 0.001), tumor site (F = 2.724, p = 0.001), age (F = 3.627, p = 0.006), and depressive symptoms (F = 5.914, p < 0.001). The 6-24-month change in social eating problems was associated with a 6-month nutritional status (F = 6.089, p = 0.002), age (F = 5.727, p = 0.004), muscle strength (F = 5.218, p = 0.006), and hearing problems (F = 5.155, p = 0.006). Results suggest monitoring social eating problems until 12-month follow-up and basing interventions on patients' features.

Trismus Occurrence and Link With Radiotherapy Doses in Head and Neck Cancer Patients Treated With Chemoradiotherapy

BACKGROUND

Chemoradiotherapy (CRT) for head and neck cancer (HNC) induces side-effects, including trismus, which impairs quality of life by causing difficulty to eat, speak, and maintain good oral hygiene, and by altering social life. Given the wide variation of reported trismus prevalence and as a first mandatory step for the preventive physiotherapy OPEN program (NCT03979924) this study evaluated trismus occurrence and its link with radiation doses.

METHODS

Study population was non-larynx HNC patients with epidermoid carcinoma treated with CRT, with or without surgery. A physiotherapist measured maximal interincisal distance before, during and after CRT, at 10 weeks and 6 months. The proportion of patients with trismus (with a 95% confidence interval) was estimated. Irradiation doses were analyzed between patients with and without trismus using non-parametric Kruskal-Wallis test.

RESULTS

We included 45 patients (77.8% male), median age 61 years (range 41-77). The proportion of trismus at baseline was 24.4%, 26.8% at 10 weeks and 37.1% at 6 months. During radiotherapy, it was 27.9% at week 3 and increased to 41.9% at week 6. Trismus occurrence at 10 weeks was higher when the radiation dose to the ipsilateral lateral pterygoid muscle was above the median value, that is, 36.8 grays.

CONCLUSION

Trismus occurrence differed according to radiation dose and cancer location. These findings highlight the necessity of early preventive physiotherapy programs to reduce trismus occurrence. The second step, of the interventional multicenter OPEN program, is currently evaluating the impact of preventive physiotherapy and patient education on trismus in a sample of 175 patients.

Photobiomodulation therapy in management of cancer therapy-induced side effects: WALT position paper 2022

Disclaimer

This article is based on recommendations from the 12th WALT Congress, Nice, October 3-6, 2018, and a follow-up review of the existing data and the clinical observations of an international multidisciplinary panel of clinicians and researchers with expertise in the area of supportive care in cancer and/or PBM clinical application and dosimetry. This article is informational in nature. As with all clinical materials, this paper should be used with a clear understanding that continued research and practice could result in new insights and recommendations. The review reflects the collective opinion and, as such, does not necessarily represent the opinion of any individual author. In no event shall the authors be liable for any decision made or action taken in reliance on the proposed protocols.

Objective

This position paper reviews the potential prophylactic and therapeutic effects of photobiomodulation (PBM) on side effects of cancer therapy, including chemotherapy (CT), radiation therapy (RT), and hematopoietic stem cell transplantation (HSCT).

Background

There is a considerable body of evidence supporting the efficacy of PBM for preventing oral mucositis (OM) in patients undergoing RT for head and neck cancer (HNC), CT, or HSCT. This could enhance patients’ quality of life, adherence to the prescribed cancer therapy, and treatment outcomes while reducing the cost of cancer care.

Methods

A literature review on PBM effectiveness and dosimetry considerations for managing certain complications of cancer therapy were conducted. A systematic review was conducted when numerous randomized controlled trials were available. Results were presented and discussed at an international consensus meeting at the World Association of photobiomoduLation Therapy (WALT) meeting in 2018 that included world expert oncologists, radiation oncologists, oral oncologists, and oral medicine professionals, physicists, engineers, and oncology researchers. The potential mechanism of action of PBM and evidence of PBM efficacy through reported outcomes for individual indications were assessed.

Results

There is a large body of evidence demonstrating the efficacy of PBM for preventing OM in certain cancer patient populations, as recently outlined by the Multinational Association for Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO). Building on these, the WALT group outlines evidence and prescribed PBM treatment parameters for prophylactic and therapeutic use in supportive care for radiodermatitis, dysphagia, xerostomia, dysgeusia, trismus, mucosal and bone necrosis, lymphedema, hand-foot syndrome, alopecia, oral and dermatologic chronic graft-versus-host disease, voice/speech alterations, peripheral neuropathy, and late fibrosis amongst cancer survivors.

Conclusions

There is robust evidence for using PBM to prevent and treat a broad range of complications in cancer care. Specific clinical practice guidelines or evidence-based expert consensus recommendations are provided. These recommendations are aimed at improving the clinical utilization of PBM therapy in supportive cancer care and promoting research in this field. It is anticipated these guidelines will be revised periodically.

Longitudinal Analysis of Swallowing Displacement Kinematics After Oropharyngeal Cancer Treatment

BACKGROUND/OBJECTIVE

Quantitative swallowing displacement kinematics evolve in patients treated for oropharyngeal squamous cell carcinoma (OPSCC). We aimed to longitudinally assess these measurements and correlate them with functional swallowing outcomes.

METHOD

A retrospective review was conducted on patients with OPSCC treated with definitive (chemo)radiation ([C]RT) or surgery with adjuvant (chemo)radiation (S-[C]RT) who completed at least two videofluoroscopic swallow studies (VFSS). Longitudinal analysis was accomplished via mixed-effects logistic regression for the Functional Oral Intake Scale (FOIS), and Penetration Aspiration Scale (PAS), and mixed-effects linear regression for kinematic measures. Spearman's correlation was conducted between changes in FOIS/PAS and kinematic measures.

RESULTS

Ninety-seven patients (76 males; mean age 61) completed 245 VFSS studies. A total of 94% had human papillomavirus (HPV)/p16 positive OPSCC and 74% were T0-T2. Sixty-four patients underwent [C]RT while 33 patients underwent S-[C]RT. After treatment, posterior pharyngeal wall at hold (PPWhold) increased 3.2 standard deviation (SD) between 0 and 6 months (p < 0.001), then decreased 2.2 SD between 6 and 12 months (p < 0.001) and did not return to baseline. Hyoid-to-larynx (HL) (p = 0.046) and maximal hyoid displacement (Hmax) + HL (p = 0.042) increased between 6 and 12 months. Hmax (p = 0.020) and Hmax + HL (p < 0.001) decreased between 12-24 months beyond baseline values. The decrease in HL and increase in PPWhold (p < 0.05) correlated with an increase in PAS. From baseline, increased pharyngeal constriction ratio correlated with decreased FOIS and PPWhold (p < 0.05).

CONCLUSIONS

Quantitative swallowing kinematic measures can effectively track changes in swallowing physiology. Increased PPWhold and restricted hyolaryngeal movement were seen in patients with OPSCC after treatment and correlated with a change in swallowing outcome, emphasizing the need for serial VFSS monitoring and targeted intervention.

Clinical and Epidemiological Characteristics of Bloodstream Infections in Head and Neck Cancer Patients: A Decadal Observational Study

This retrospective study aims to describe the clinico-epidemiological characteristics of bloodstream infections (BSIs) and the risk factors in patients with head and neck cancer (n = 227) treated at the Department of Otolaryngology, Head and Neck Surgery, Tohoku University Hospital between April 2011 and March 2021. Overall, 23.3% of blood cultures were positive. In the culture-positive group, catheter-related bloodstream infections (CRBSIs) were the most common (38.8%), followed by respiratory tract infections (19.4%), and catheter-associated urinary tract infections (6.0%). Methicillin-resistant Staphylococcus aureus (26.9%), Staphylococcus epidermidis (17.9%), and Pseudomonas aeruginosa (10.4%) infections were common. The most frequent treatment for head and neck cancer was surgery (23.9%), followed by treatment interval or palliative care (19.4%), and single radiotherapy (13.4%). The 30-day mortality rate was significantly higher in the BSI than in the non-BSI group (10.4% vs. 1.8%, respectively). CRBSIs are the most frequent source of BSIs in patients with head and neck cancer. In conclusion, central venous catheters or port insertion should be used for a short period to prevent CRBSIs. The risk of developing BSI should be considered in patients with pneumonia. Understanding the epidemiology of BSIs is crucial for diagnosing, preventing, and controlling infections in patients with head and neck cancer.

Metabolism-Related Bioinformatics Analysis Reveals That HPRT1 Facilitates the Progression of Oral Squamous Cell Carcinoma In Vitro

Objectives

Many studies have shown that dysregulation of metabolism contributes to oncogenesis. However, the exact roles of metabolism-related genes (MRGs) in oral squamous cell carcinoma (OSCC) remain unclear. Thus, we aimed to identify a prognostic signature related to MRGs in OSCC.

Methods

The gene sequencing data of OSCC samples and the MRG set were downloaded from The Cancer Genome Atlas (TCGA) and the Molecular Signatures Database (MSigDB). The Wilcoxon rank-sum test was used to identify differentially expressed MRGs. Then, a prognostic signature was established by multivariate Cox regression analysis. Finally, prognosis-related MRGs were selected and further validated in OSCC tissues and cell lines.

Results

A prognostic signature that included 8 MRGs was constructed. Multiple survival analysis revealed that only HPRT1 might be an independent biomarker and indicator of poor overall survival in OSCC patients. The expression of HPRT1 was then found to be upregulated in OSCC tissues and cell lines, and suppression of HPRT1 gene expression by siRNA inhibited the proliferation, migration, and invasion of OSCC cells in vitro.

Conclusions

MRGs play an important role in the development of OSCC. Furthermore, HPRT1 might be an independent biomarker of OSCC and enhance OSCC proliferation, migration, and invasion in vitro; these results emphasize the potential utility of HPRT1 in OSCC therapy.

Comprehensive Analysis of the Immune and Prognostic Implication of TRIM8 in Breast Cancer

Background: Breast cancer remains one of most lethal illnesses and the most common malignancies among women, making it important to discover novel biomarkers and therapeutic targets for the disease. Immunotherapy has become a promising therapeutic tool for breast cancer. The role of TRIM8 in breast cancer has rarely been reported.

Method: Here we identified TRIM8 expression and its potential function on survival in patients with breast cancer using TCGA (The cancer genome atlas), GEO (Gene expression omnibus) database and METABRIC (Molecular Taxonomy of Breast Cancer International Consortium). Then, TIMER and TISIDB databases were used to investigate the correlations between TRIM8 mRNA levels and immune characteristics. Using stepwise cox regression, we established an immune prognostic signature based on five differentially expression immune-related genes (DE-IRGs). Finally, a nomogram, accompanied by a calibration curve was proposed to predict 1-, 3-, and 5-year survival for breast cancer patients.

Results: We found that TRIM8 expression was dramatically lower in breast cancer tissues in comparison with normal tissues. Lower TRIM8 expression was related with worse prognosis in breast cancer. TIMER and TISIDB analysis showed that there were strong correlations between TRIM8 expression and immune characteristics. The receiver operating characteristic (ROC) curve confirmed the good performance in survival prediction and showed good accuracy of the immune prognostic signature. We demonstrated the model usefulness of predictions by nomogram and calibration curves. Our findings indicated that TRIM8 might be a potential link between progression and prognosis survival of breast cancer.

Conclusion: This is a comprehensive study to reveal that tripartite motif 8 (TRIM8) may serve as a potential prognostic biomarker associating with immune characteristics and provide a novel therapeutic target for the treatment of breast cancer.

Speech pathology service enhancement for people with head and neck cancer living in rural areas: Using a concept mapping approach to inform service change

BACKGROUND

Speech pathology (SP) services provide swallowing and communication intervention to people with head and neck cancer (HNC) across the continuum of care. However, difficulties exist with access and delivery of services in rural areas. The study aim was to identify actionable goals for SP change, utilizing a concept mapping approach.

METHODS

Eleven SP staff from two regional/remote services completed the concept mapping process. Multivariate analysis and multidimensional scaling were used to develop a final set of prioritized goals for change.

RESULTS

Between the two participating health services, 30 actionable goals were identified within the "green-zone" on the go-zone graph of importance and changeability. Among the most highly rated areas for change was the need to deliver and receive more support for training, mentoring, and supervision to consolidate skills.

CONCLUSIONS

This methodology enabled identification of prioritized, actionable changes to improve SP services for people with HNC living in regional/remote areas.

Newly designed flat surface artificial tongue system for speech improvement in glossectomy patients: A preliminary study

PURPOSE

To design an efficient tongue prosthesis with reproducibility and to objectively evaluate improvement in speech function.

METHODS

A silicon anatomical artificial tongue (AT) and a flat surface artificial tongue system (FTS) were used in our study. Twenty healthy participants (10 males and 10 females, 26.3 ± 1.8 years) were fitted with a tongue movement suppression appliance (TSA) that fit the dental arch to simulate the glossectomy condition. TSA, TSA + FTS, and TSA + AT simulated the state of glossectomy patients without artificial tongue, with normal artificial tongue, and newly designed artificial tongue, respectively. Three speech intelligibility tests were performed for each of the following conditions: pronouncing 100 Japanese monosyllables, 40 Japanese words, and reading a short story. One-way ANOVA, Wilcoxon signed-rank test, and Tukey-Kramer post-hoc test were used for statistical analyses.

RESULTS

Significant differences were observed for 100 Japanese monosylla bles and 40 Japanese words between the TSA + FTS, TSA, and TSA + AT conditions (p ‹ 0.05). Regarding the speech intelligibility test for reading a short story, the TSA + FTS condition resulted in a significantly higher speech intelligibility than the TSA and TSA + AT conditions (p ‹ 0.05).

CONCLUSIONS

A flat surface artificial tongue system contributed to the improvement in speech function. This structure can be easily used in cases where conventional artificial tongue are applicable, regardless of variation in the oral condition; thus, making it a widely applicable treatment option for glossectomy patients.

Radiation therapy in head and neck cancer

This review summarizes the beginning of radiotherapy, techniques of modern radiation therapy with different types, toxicities induced by radiotherapy and their management. Head and neck radiation therapy is still improving for the better management and control of the cancer and induced radiotherapy toxicities.

Cost-utility and cost-effectiveness of a guided self-help head and neck exercise program for patients treated with total laryngectomy: Results of a multi-center randomized controlled trial

OBJECTIVES

The guided self-help exercise program called In Tune without Cords (ITwC) is effective in improving swallowing problems and communication among patients treated with a total laryngectomy (TL). This study investigated the cost-utility and cost-effectiveness of ITwC.

MATERIALS AND METHODS

Patients within 5 years after TL were included in this randomized controlled trial. Patients in the intervention group (n = 46) received access to the self-help exercise program with flexibility, range-of-motion and lymphedema exercises, and a self-care education program. Patients in the control group (n = 46) received access to the self-care education program only. Healthcare utilization (iMCQ), productivity losses (iPCQ), health status (EQ-5D-3L, EORTC QLU-C10D) and swallowing problems (SwalQol) were measured at baseline, 3- and 6-months follow-up. Hospital costs were extracted from medical files. Mean total costs and effects (quality-adjusted life-years (QALYs) or SwalQol score) were compared with regression analyses using bias-corrected accelerated bootstrapping.

RESULTS

Mean total costs were non-significantly lower (-€685) and QALYs were significantly higher (+0.06) in the intervention compared to the control group. The probability that the intervention is less costly and more effective was 73%. Sensitivity analyses with adjustment for baseline costs and EQ-5D scores showed non-significantly higher costs (+€119 to +€364) and QALYs (+0.02 to +0.03). A sensitivity analysis using the QLU-C10D to calculate QALYs showed higher costs (+€741) and lower QALYs (-0.01) and an analysis that used the SwalQol showed higher costs (+€232) and higher effects (improvement of 6 points on a 0-100 scale).

CONCLUSION

ITwC is likely to be effective, but possibly at higher expenses.

Evolving target volume concepts in locally advanced non-small cell lung cancer

Radiotherapy (RT) target volume concepts for locally advanced lung cancer have been under discussion for years. Although they may be as important as treatment doses, many aspects of them are still based on conventions, which, due to the paucity of prospective data, rely on long-term practice or on clinical knowledge and experience (e.g., on patterns of spread or recurrence). However, in recent years, large improvements have been made in medical imaging and molecular imaging methods have been implemented, which are of great interest in RT. For lung cancer, in recent years, 18F-fluoro-desoxy-glucose (FDG)-positron-emission tomography (PET)/computed tomography (CT) has shown a superior diagnostic accuracy as compare to conventional imaging and has become an indispensable standard tool for diagnostic workup, staging and response assessment. This offers the chance to optimize target volume concepts in relation to modern imaging. While actual recommendations as the EORTC or ESTRO-ACROP guidelines already include imaging standards, the recently published PET-Plan trial prospectively investigated conventional versus imaging guided target volumes in relation to patient outcome. The results of this trial may help to further refine standards. The current review gives a practical overview on procedures for pre-treatment imaging and target volume delineation in locally advanced non-small cell lung cancer (NSCLC) in synopsis of the procedures established by the PET-Plan trial with the actual EORTC and ACROP guidelines.

European white paper: oropharyngeal dysphagia in head and neck cancer

PURPOSE

To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe.

METHODS

Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion.

RESULTS

Twenty-four sections on HNC-specific OD topics.

CONCLUSION

This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Improvement of a delayed swallowing reflex following treatment for advanced head and neck cancer

Background

The latency of the swallowing reflex is an important factor causing dysphagia in head and neck cancer patients. Although there are many reports comparing voluntary swallowing function before and after treatment, few studies have focused on the latency of the swallowing reflex, which is a risk factor for pneumonia due to silent aspiration. The aim of this retrospective study was to clarify the changes in the latency of the swallowing reflex before and after treatment.

Methods

The latency of the swallowing reflex was quantified using the time from the injection of 1 ml of distilled water into the pharynx through a nasal catheter to the onset of swallowing.

Results

The latency time of the swallowing reflex was significantly decreased 3 months after treatment compared to before treatment. A significant reduction was also observed in patients with pharyngeal cancer who underwent chemoradiation therapy.

Conclusions

This retrospective study showed that a delayed swallowing reflex improved with treatment in advanced head and neck cancer patients.

Neck Disability and Swallowing Function in Posttreatment Head and Neck Cancer Patients

Objective

To examine the relationship between symptoms of neck disability and swallowing dysfunction among head and neck cancer (HNC) survivors.

Study Design

Cross-sectional analysis.

Setting

Single-center, university-affiliated HNC survivorship clinic.

Subjects and Methods

Survivors’ patient-reported symptoms of neck disability and swallowing dysfunction were prospectively collected from March 2017 to May 2018. Neck disability and swallowing dysfunction were measured using the Neck Disability Index and Eating Assessment Tool (EAT-10), respectively. Linear regression was used to analyze the association between neck disability and swallowing dysfunction.

Results

A total of 179 survivors, predominantly male (n = 130, 72.6%) with an average age of 64.64 ± 9.91 years, were included in the analysis. Primary cancer sites were oropharynx (n = 85, 47.5%), oral cavity (n = 59, 33.0%), and larynx/hypopharynx (n = 35, 19.5%). Mean EAT-10 score was 10.07 ± 10.89 (range = 0-40; >2 indicative of swallowing dysfunction). Survivors treated for early stage cancer had lower EAT-10 scores than those with advanced stage (early = 3.55 ± 7.46; advanced = 11.95 ± 11.02, P < .001). After controlling for age, time since treatment, American Joint Committee on Cancer stage, and treatment modality, the EAT-10 score for patients with mild neck disability was 6.88 (95% confidence interval [CI], 3.71-10.06; P < .001) points higher than those without neck disability, and the score for those with moderate-complete neck disability was 13.65 (95% CI, 9.47-17.83; P < .001) points higher than those without neck disability.

Conclusions

Swallowing dysfunction is a commonly recognized effect of HNC treatment. The prevalence and burden of neck disability are shown to be highly correlated with swallowing dysfunction. These results support the need for comprehensive, multidisciplinary rehabilitation interventions for patients with HNC.

Dose-volume correlates of the prevalence of patient-reported trismus in long-term survivorship after oropharyngeal IMRT: A cross-sectional dosimetric analysis

PURPOSE

To ascertain the dose-toxicity relationship for the prevalence of self-reported trismus in long-term survivors after intensity-modulated radiotherapy (IMRT) for oropharyngeal carcinoma (OPC).

MATERIALS AND METHODS

Self-reported mouth opening was ascertained prospectively via a cross-sectional survey of OPC survivors using the intraoral finger-test. RT dose-volume histograms (DVHs) were generated for the following masticatory regions of interest: medial pterygoid, lateral pterygoid, and masseter muscles which were designated as ipsilateral or contralateral to the primary tumor. Trismus was defined as self-reported mouth opening of <3 finger-widths. Recursive partitioning analysis (RPA) was performed to identify the dose-volume thresholds associated with late trismus.

RESULTS

At a median follow-up time of 72 months (95% CI 68-74), 168 of the 587 (29%) survey respondents reported late trismus. Multivariate analysis demonstrated a significant association between late trismus and the following clinical variables: tonsillar primary site, advanced T stage, or higher total RT dose. RPA showed DVH-derived ipsilateral lateral pterygoid (ILP) mean dose of 61 Gy and volume receiving 27 Gy of at least 98.6% were independently associated with late trismus. The association between the ILP dosimetric parameters and the prevalence of late trismus was maintained after adjustment for clinical variables.

CONCLUSION

The integral dose of IMRT results in unavoidable low/intermediate dose to non-target masticatory muscles that is associated with increased prevalence of late trismus in OPC survivors. Whenever clinically and technically applicable, applying the proposed dosimetric constraints to the ILP (V27 <98.6 and D_mean <61 Gy) may reduce the prevalence of late trismus after IMRT for OPC patients.

Assessment of Predictive Scoring System for 90-Day Mortality Among Patients With Locally Advanced Head and Neck Squamous Cell Carcinoma Who Have Completed Concurrent Chemoradiotherapy

IMPORTANCE

There is currently no system to predict 90-day morality among patients with locally advanced head and neck squamous cell carcinoma (HNSCC) after the completion of concurrent chemoradiotherapy (CCRT).

OBJECTIVE

To validate the accuracy of a predictive scoring system for 90-day mortality among patients with locally advanced HNSCC who have completed CCRT.

DESIGN, SETTING, AND PARTICIPANTS

This prognostic study included 16 029 patients with HNSCC who completed CCRT between January 2006 and December 2015. Data were extracted from the Taiwan Cancer Registry Database. A risk scoring system was developed based on significant risk factors and corresponding risk coefficients. Data analysis was conducted from June 2018 to February 2019.

EXPOSURES

Mortality within 90 days of completion of definitive CCRT.

MAIN OUTCOMES AND MEASURES

The 90-day mortality rate after completion of CCRT and the accuracy of the scoring system, based on a comparison of mortality rates between training and test data sets.

RESULTS

Among 16 029 patients with locally advanced HNSCC, 1068 (6.66%; 1016 [95.1%] men; mean [SD] age, 55.11 [11.45] years) died before reaching the 90-day threshold, and 14 961 (93.4%; 14 080 [94.1%] men; mean [SD] age, 52.07 [9.99] years) survived. Multivariable analysis revealed that being aged 50 years or older (adjusted hazard ratio [aHR], 1.263; 95% CI, 1.104-1.445; P < .001), being aged 70 years or older (aHR, 2.183; 95% CI, 1.801-2.645; P < .001), having pneumonia (aHR, 1.946; 95% CI, 1.636-2.314; P < .001), having sepsis (aHR, 3.005; 95% CI, 2.503-3.607; P < .001), having hemiplegia (aHR, 1.430; 95% CI, 1.085-1.884; P = .01), having moderate or severe renal disease (aHR, 2.054; 95% CI, 1.643-2.568; P < .001), having leukemia (aHR, 4.541; 95% CI, 1.132-8.207; P = .03), and having non-HNSCC metastatic solid cancers (aHR, 1.457; 95% CI, 1.292-1.644; P < .001) were significant risk factors for 90-day mortality. Risk scores were categorized as very low risk (score of 0), low risk (score 1-3), moderate risk (score 4-6), and high risk (score ≥7), with 90-day mortality rates of 3.37%, 5.00% to 10.98%, 16.15% to 29.13%, and 33.93% to 37.50%, respectively. Mortality rates for patients with the same risk score in the training and test data sets were similar (score of 0, 3.27% vs 3.66%; score of 6, 27.42% vs 25.00%).

CONCLUSIONS AND RELEVANCE

In this prognostic study, a 90-day mortality scoring system accurately predicted 90-day mortality among patients with locally advanced HNSCC who completed CCRT.

Long-term swallowing, trismus, and speech outcomes after combined chemoradiotherapy and preventive rehabilitation for head and neck cancer; 10-year plus update

BACKGROUND

The objective of this study was to explore the 10-year plus outcomes of Intensity Modulated Radiotherapy with concomitant chemotherapy (CRT) combined with preventive swallowing rehabilitation (CRT+) for head and neck cancer (HNC).

METHODS

Subjective and objective swallowing, trismus, and speech related outcomes were assessed at 10-year plus after CRT+. Outcomes were compared to previously published 6-year results of the same cohort.

RESULTS

Fourteen of the 22 patients at 6-year follow-up were evaluable. Although objective swallowing-related outcomes showed no deterioration (eg, no feeding tube dependency and no pneumonia), swallowing-related quality of life slightly deteriorated over time. No patients had or perceived trismus. Voice and speech questionnaires showed little problems in daily life. Overall quality of life (QOL) was good.

CONCLUSIONS

After CRT with preventive rehabilitation exercises for advanced HNC, swallowing, trismus, and speech related outcomes moderately deteriorated from 6 to 10 years, with an on average good overall QOL after.

Impact of Neck Disability on Health-Related Quality of Life among Head and Neck Cancer Survivors

OBJECTIVE

Although neck impairment has been described following surgical resection, limited studies have investigated its prevalence in nonsurgical treatment. The purpose of this study is to determine the prevalence and predictors of neck disability following head and neck cancer (HNC) treatment and to explore its association with quality of life (QOL).

STUDY DESIGN

Cross-sectional study.

SETTING

HNC survivorship clinic.

SUBJECTS AND METHODS

We identified 214 survivors who completed treatment ≥1 year prior to evaluation in the clinic. Self-reported neck impairment was measured using the Neck Disability Index. QOL was measured using the University of Washington QOL Questionnaire, with physical and social subscale scores calculated. Regression analysis and trend tests were employed to explore associations.

RESULTS

Over half of survivors (54.2%) reported neck disability. The odds of neck disability in survivors who received nonsurgical treatment and those who received surgery plus adjuvant treatment were 3.46 and 4.98 times higher compared to surgery alone (P = .008, P = .004). Survivors who underwent surgery only had higher physical and social QOL than those who received nonsurgical treatment (physical QOL: P < .001, social QOL: P = .023) and those who received surgery plus adjuvant treatment (physical QOL: P < .001, social QOL: P = .039).

CONCLUSION

This study revealed a high prevalence of neck disability following nonsurgical treatment. While neck disability is an established sequela of surgical resection, the impact of nonsurgical treatment has gone unrecognized. Early identification and intervention to prevent progression of neck disability are crucial to optimize QOL.

Interactive website for head and neck cancer patients: Adherence and coping program to prevent dysphagia after radiation

INTRODUCTION

Pharyngeal and laryngeal cancers are highly curable; however survivors are at high risk for long-term dysphagia after radiation. To address lack of access to preventive care in community settings, we developed a responsive web-based application to help patients adhere to preventive swallowing exercises and cope with radiation side effects. We conducted an interim study analysis to determine website usage characteristics and to examine the effect size for future trials.

METHODS

Pharyngeal and laryngeal cancer patients were recruited for enrollment by speech language pathologists before primary radiation and introduced to the interactive website. The program (English and Spanish) features tracking logs for preventive exercises, instructional videos, patient stories and search features. Patients' self-reported swallowing function was assessed with the MD Anderson Dysphagia Inventory (MDADI) at baseline and at 6 months. Adherence to preventive exercises was assessed during the 10 week intervention. Number of unique website visits, total duration of website exposure, and rankings of the most popular webpages were calculated. Preliminary regression models were run using adherence and MDADI as outcomes.

RESULTS

Of the 160 enrolled, 96 had 10-week adherence data and 61 had 6-month MDADI data. The average age was 63 (SD = 12.26), 49.4% were from rural counties, 44% had a high school education or lower, and 42% reported annual income of $30,000 or less. The average number of visits was 5.49 (SD = 9.96) and the average total time spent with the website was 41.09 min (SD =88.48). Preliminary analyses indicated that number of unique visits to the website was independently associated with increased adherence to preventive exercises (p = .001-.008).

CONCLUSION

Our website showed significant effects in promoting adherence to swallowing exercises. However, our return visit rate showed that the platform needs improvement in navigability and usability for this older population undergoing challenging treatment in community settings with low resources.

Swallowing disorders after treatment for head and neck cancer

Background

Dysphagia is a common consequence of treatment for head and neck cancer (HNC). The purpose of the study was to evaluate the prevalence of dysphagia in a group of patients treated for HNC in Slovenia, and to identify factors contributing to the development of dysphagia.

Patients and methods

One-hundred-nine consecutive patients treated for HNC at two tertiary centers were recruited during their follow-up visits. They fulfilled EORTC QLQ-H&N35 and “Swallowing Disorders after Head and Neck Cancer Treatment questionnaire” questionnaires. Patients with dysphagia were compared to those without it.

Results

Problems with swallowing were identified in 41.3% of the patients. Dysphagia affected their social life (in 75.6%), especially eating in public (in 80%). Dysphagia was found the most often in the patients with oral cavity and/or oropharyngeal cancer (in 57.6%) and in those treated less than 2 years ago (p = 0.014). In univariate analysis, a significant relationship was observed between dysphagia prevalence and some of the consequences of anti-cancer treatment (impaired mouth opening, sticky saliva, loss of smell, impaired taste, oral and throat pain, persistent cough, and hoarseness), radiotherapy (p = 0.003), and symptoms of gastroesophageal reflux (p = 0.027). After multiple regression modelling only persistent cough remained.

Conclusions

In order to improve swallowing abilities and, consequently, quality of life of the patients with HNC a systematic rehabilitation of swallowing should be organized. A special emphasis should be given to gastroesophageal reflux treatment before, during and after therapy for HNC

Factors associated with depression over time in head and neck cancer patients: A systematic review

Objective

To systematically review the literature on factors associated with a clinical diagnosis of depression or symptoms of depression (depression) among head and neck cancer (HNC) patients.

Methods

The search was conducted in PubMed, PsycINFO, and CINAHL. Studies were included if they investigated factors associated with depression among HNC patients, they were of prospective or longitudinal nature, and English full text was available. The search, data extraction, and quality assessment were performed by two authors. Based on the data extraction and quality assessment, the level of evidence was determined.

Results

In total, 35 studies were included: 21 on factors associated with depression at a single (later) time point, 10 on the course of depression, and four on both. In total, 77 sociodemographic, lifestyle, clinical, patient‐reported outcome measures, and inflammatory factors were extracted. Regarding depression at a single time point, there was strong evidence that depression at an earlier time point was significantly associated. For all other factors, evidence was inconclusive, although evidence suggests that age, marital status, education, ethnicity, hospital/region, sleep, smoking, alcohol, surgery, treatment, tumor location, and recurrence are not important associated factors. Regarding the course of depression, we found inconclusive evidence for all factors, although evidence suggests that gender, age, chemotherapy, pain, disease stage, treatment, and tumor location are not important associated factors.

Conclusion

Depression at an earlier time point is significantly associated with depression later on. Several sociodemographic and clinical factors seem not to be important factors associated with depression. For other factors, further research is warranted.

An interactive surgical simulation tool to assess the consequences of a partial glossectomy on a biomechanical model of the tongue

Oral cancer surgery has a negative influence on the quality of life (QOL). As a result of the complex physiology involved in oral functions, estimation of surgical effects on functionality remains difficult. We present a user-friendly biomechanical simulation of tongue surgery, including closure with suturing and scar formation, followed by an automated adaptation of a finite element (FE) model to the shape of the tongue. Different configurations of our FE model were evaluated and compared to a well-established FE model. We showed that the post-operative impairment as predicted by our model was qualitatively comparable to a patient case for five different tongue maneuvers.

Associations between pre-, post-, and peri-operative variables and health resource use following surgery for head and neck cancer

OBJECTIVE

We examined associations between pre-, post-, and peri-operative variables and health resource use in head and neck cancer patients.

METHODS

Patients (N = 183) who were seen for a pre-surgical consult between January 2012 and December 2014 completed surveys that assessed medical history, a patient-reported outcome measure (PROM) of dysphagia, and quality of life (QOL). After surgery, peri-operative (e.g., tracheostomy, feeding tube) and post-operative (e.g., complications) variables were abstracted from patients' medical records.

RESULTS

Multivariate regression models using backward elimination showed that pre-surgical University of Washington Quality of Life (UW-QOL) Inventory and M.D. Anderson Dysphagia Inventory (MDADI) composite scores, documented surgical complications, and having a tracheostomy, were all significant predictors of hospital length of stay, explaining 57% of the total variance (F(5, 160) = 18.71, p < .001). Male gender, psychiatric history, and lower pre-surgical MDADI scores significantly predicted thirty-day unplanned readmissions (30dUR). Pre-surgical MDADI composite scores also significantly predicted emergencey department (ED) visits within 30 days of initial hospital discharge (p = .02).

CONCLUSIONS

Assessment of PROMs and QOL in the pre-surgical setting may assist providers in identifying patients at risk for prolonged LOS and increased health resource use after hospital discharge.

Electronic Swallowing Intervention Package to Support Swallowing Function in Patients With Head and Neck Cancer: Development and Feasibility Study

Background

Many patients undergoing treatment for head and neck cancer (HNC) experience significant swallowing difficulties, and there is some evidence that swallowing exercises may improve outcomes, including quality of life. This feasibility study developed an evidence-based, practical Swallowing Intervention Package (SiP) for patients undergoing chemoradiotherapy (CRT) for HNC. As part of the study, an electronic version of SiP (e-SiP) was concurrently developed to support patients to self-manage during treatment. This paper reports on the e-SiP component of this work.

Objective

The objective of our study was to develop and conduct a preliminary evaluation of an electronic support system (e-SiP) for patients undergoing CRT for HNC.

Methods

The study was conducted using a recognized mHealth development and evaluation framework and involved health professionals and patients who were undergoing CRT for HNC. The scoping stage of e-SiP development investigated the potential usefulness of the app, exploring how e-SiP would look and feel and what content would be appropriate to provide. Patient and carer focus groups and a health professionals’ consensus day were used as means of data gathering around potential e-SiP content. A repeat focus group looked at an outline version of e-SiP and informed the next stage of its development with regard to refining the requirements for the tool. This was followed by further development and a testing stage of e-SiP that involved the coding of a prototype, which was then evaluated using a series of steering group meetings, semistructured interviews with both patients and health care professionals, and analysis of e-SiP log data.

Results

Feedback from focus groups and health professional interviews was very positive, and it was felt e-SiP use would support and encourage patients in conducting their swallowing exercises. However, of the 10 patients who were offered e-SiP, only 2 opted to use it. For these patients, the aspects of the e-SiP app were considered useful, in particular, the ease of keeping a diary of exercises performed. Interviews with users and nonusers suggested significant barriers to its use. Most significantly, the lack of flexibility of the platform on which e-SiP could be accessed appeared a dominant factor in deterring e-SiP use.

Conclusions

The results suggest that further research needs to be conducted around the implementation of e-SiP. This involves evaluating how e-SiP can be better integrated into usual care and through patient training and staff engagement, can be perceived as a beneficial tool to help support patients in conducting swallowing exercises.

Potential Benefits of Annona muricata in Combating Cancer: A Review

The incidence of cancer is increasing each year, which generates concerns regarding the efficacy of the current treatment options. This has caused patients to seek alternatives to complement or to replace surgery, chemotherapy and radiotherapy. Annona muricata and other plants have been shown to have promising compounds that can be utilised in the treatment of cancer. Native to the tropical and subtropical parts of the world, A. muricata plant extracts contain compounds that are particularly effective against cancer cells. In light of increasing concerns regarding the limitations of cancer treatment in hospitals, this review attempts to highlight the benefits of A. muricata and its potential to be integrated as one of the treatment options against cancer.

Tumor volume as a predictor of survival in T3 glottic carcinoma: A novel approach to patient selection

BACKGROUND

The optimal treatment for T3 glottic cancers continues to be debated. Organ preservation has become the standard of care, but not all tumors respond equally. The purpose of this was to investigate the long-term survival outcomes of organ preservation protocols based on tumor volume.

METHODS

A retrospective review of prospectively collected data from 1966 to 2016 was performed. Patients with T3 vocal cord cancer treated with radiation therapy (RT) at the University of Florida were included. Local control rates as well as survival rates were determined with a Kaplan Meier and Cox regression analysis. Survival was analyzed as a function of tumor volume and an optimal cut point was determined.

RESULTS

107/234 patients were included. 79% received RT and 21% chemo-RT. 5-year local control was 61.5% and 5-year disease specific survival was 79.3%. Tumor volume was a significant predictor of survival (p = 0.007). An optimal cut point for tumor volume was 2.5 cc. Patients with tumor volumes ≥2.5 cc had significantly worse (p < 0.05) tumor control rates (100% vs. 70.4%).

CONCLUSION

Tumor volume is a significant predictor of survival outcomes in T3 vocal cord cancers, but will need external validation. Tumors <2.5 cc have favorable outcomes. Those with higher volume tumors should be counselled appropriately and be considered for primary surgical management.

Home-based telehealth service for swallowing and nutrition management following head and neck cancer treatment

Introduction

Following (chemo)radiotherapy (C/RT) for head and neck cancer (HNC), patients return to hospital for regular outpatient reviews with speech pathology (SP) and nutrition and dietetics (ND) for acute symptom monitoring, nutritional management, and swallowing and communication rehabilitation. The aim of the current study was to determine the feasibility of a home-based telehealth model for delivering SP and ND reviews, to provide patients with more convenient access to these appointments.

Methods

Service outcomes, costs, and consumer satisfaction were examined across 30 matched participants: 15 supported via the standard model of care (SMOC), and 15 via the home-based telehealth model of care (TMOC).

Results

All patients were successfully managed via telehealth. The TMOC was more efficient, with a reduced number ( p < 0.003) and duration ( p < 0.01) of appointments required until discharge. Significant patient cost savings ( p = 0.002) were reported for the TMOC due to decreased travel requirements. While staff costs were reduced, additional telehealth equipment levies resulted in a lower but non-significant overall cost difference to the health service when using the TMOC. High satisfaction was reported by all participants attending the TMOC.

Discussion

The findings support the feasibility of a home-based telehealth model for conducting SP and ND reviews post C/RT for HNC.

An evaluation of nutrition intervention during radiation therapy in patients with locoregionally advanced nasopharyngeal carcinoma

Purpose

To evaluate the effectiveness of nutrition intervention during radiation for patients with locoregionally advanced (III-IVa) nasopharyngeal carcinoma (NPC).

Materials and Methods

We retrospectively reviewed 117 patients with locoregionally advanced (III-IVa) NPC treated between December 2015 and March 2016 in Zhejiang Cancer Hospital. All the patients underwent radical chemo-radiotherapy. First, all the patients were divided into the nutrition intervention group and the control group, depending on whether they accepted nutrition intervention. Repeated measures were used to analyze the change of nutritional indicators before, during, and after radiation therapy and to simultaneously compare the difference in nutritional status between the two groups at the same time point. Subsequently, the 117 patients were divided into the malnourished group (weight loss > 5%) and the non-malnourished group (weight loss ≤ 5%) according to whether their weight loss was over 5% of their body weight during radiotherapy. Chi-square tests and logistic regression analysis were used to explore the influence factors for the weight loss.

Results

The repeated measures showed that all indicators including weight, body mass index (BMI), albumin, pre-albumin(PA), and prognostic nutritional index (PNI) dramatically declined in both groups compared with their levels before radiation therapy (All p < 0.001). However, there was no significant difference between the intervention and non-intervention groups regarding the mean values of nutritional indicators at the same time point, that before, during, and after radiation therapy, except BMI (All p > 0.05). Logistic regression analysis revealed grade ≥ 3 radiation-induced oral mucositis as the prognostic factor for a poor nutrition status (odds ratio, OR = 3.232, p = 0.021, confidence interval, CI [1.198, 8.820]). Besides this, patients with a decrease of >15% in pre-albumin level were more likely to be malnourished (OR = 2.442, p = 0.041, CI [1.036, 5.757]). Similar to that observed in our former analysis, we did not find that existing nutrition intervention can significantly improve nutritional status (OR = 1.217, p = 0.704, CI [0.042, 3.348]).

Conclusions

Our study shows that the nutritional status of the patients gradually declined during treatment. We concluded that grade ≥ 3 radiation-induced oral mucositis would aggravate the extent of malnutrition during radiation therapy in patients with locoregionally advanced NPC. Pre-albumin level was a predictive marker for weight loss in patients with NPC. However, current nutrition intervention during radiation therapy can't significantly reverse nutritional status.

Self-management strategies used by head and neck cancer survivors following completion of primary treatment: A directed content analysis

OBJECTIVE

Head and neck cancer (HNC) survivors encounter unique challenges following treatment. This study aimed to identify self-management strategies that HNC survivors use to overcome these posttreatment challenges.

METHODS

Twenty-seven individuals from 4 designated cancer centres in Ireland were interviewed about self-management strategies that helped them overcome challenges following HNC treatment. Interviews were audio-recorded, transcribed, and analysed using directed content analysis.

RESULTS

Twenty self-management strategy types (encompassing 77 specific strategies) were identified. The most frequently used self-management strategy types were self-sustaining (used by 26 survivors), self-motivating (n = 25), and proactive problem solving (n = 25). The most frequently used specific strategies were adaptive approaches to ongoing physical consequences of HNC and its treatment (n = 24), customising dietary practices (n = 24), and maintaining a positive outlook (n = 22).

CONCLUSIONS

The study identified strategies that helped HNC survivors to self-manage posttreatment challenges. This information could inform the design/development of self-management interventions tailored towards HNC survivors.

A comparison of oncological outcomes between transoral surgical and non-surgical treatment protocols in the management of oropharyngeal squamous cell carcinoma

Background:

The incidence of oropharyngeal squamous cell carcinoma in the Western world is increasing, with the human papillomavirus epidemic implicated in this observed trend. The optimal treatment modality is yet undetermined regarding oncological outcomes.

Methods:

This study comprised 98 patients with oropharyngeal squamous cell carcinoma, treated with either primary transoral surgery with adjuvant therapy or primary chemoradiotherapy with curative intent, between 2008 and 2012. Clinicopathological characteristics including tumour–node–metastasis stage, human papillomavirus status, treatment modality, recurrence and overall survival were collated.

Results:

Five per cent of primary surgical patients had locoregional recurrences compared with 25 per cent of primary chemoradiotherapy patients. A lower rate of locoregional recurrence was observed in the human papillomavirus positive group.

Conclusion:

This paper reports higher rates of overall survival and local control for oropharyngeal squamous cell carcinoma treated with primary surgery compared with primary chemoradiotherapy. This reflects overall lower tumour stage and higher human papillomavirus status in this group.

Randomized controlled trial of a multisite speech pathology telepractice service providing swallowing and communication intervention to patients with head and neck cancer: Evaluation of service outcomes

BACKGROUND

The purpose of this study was to present our evaluation of a new speech pathology telepractice service supporting the swallowing and communication management of patients with head and neck cancer.

METHODS

A multicenter randomized controlled trial was conducted within a large public cancer service. Referrals from speech pathologists at 3 regional sites (spoke sites) were managed by a specialist clinician from a cancer center (hub site) either via standard care (phone/email support/appointments at the hub site) or a newly established telepractice service (online consultation between the hub site and spoke site).

RESULTS

Eighty-two referrals (39 for standard care and 43 for telepractice care) were managed. Service efficiency favoring the telepractice model was reported with a significant reduction in the number (p = .004) and duration (p = .024) of contact events required to manage the referrals.

Dysphagia, Speech, Voice, and Trismus following Radiotherapy and/or Chemotherapy in Patients with Head and Neck Carcinoma: Review of the Literature

Introduction. Patients with head and neck cancer suffer from various impairments due to the primary illness, as well as secondary consequences of the oncological treatment. This systematic review describes the effects of radiotherapy and/or chemotherapy on the functions of the upper aerodigestive tract in patients with head and neck cancer. Methods. A systematic literature search was performed by two independent reviewers using the electronic databases PubMed and Embase. All dates up to May 2016 were included. Results. Of the 947 abstracts, sixty articles met the inclusion criteria and described one or more aspects of the sequelae of radiotherapy and/or chemotherapy. Forty studies described swallowing-related problems, 24 described voice-related problems, seven described trismus, and 25 studies described general quality of life. Only 14 articles reported that speech pathologists conducted the interventions, of which only six articles described in detail what the interventions involved. Conclusion. In general, voice quality improved following intervention, whereas quality of life, dysphagia, and oral intake deteriorated during and after treatment. However, as a consequence of the diversity in treatment protocols and patient characteristics, the conclusions of most studies cannot be easily generalised. Further research on the effects of oncological interventions on the upper aerodigestive tract is needed.

Development and feasibility of a Swallowing intervention Package (SiP) for patients receiving radiotherapy treatment for head and neck cancer-the SiP study protocol

Background

Head and neck cancer (HNC) is the sixth most common cancer worldwide, and the functional, psychological and social consequences of HNC cancer and its treatment can be severe and chronic. Dysphagia (swallowing problems) affects up to two thirds of patients undergoing combined chemoradiotherapy. Recent reviews suggest that prophylactic swallowing exercises may improve a range of short- and long-term outcomes; however, the importance of psychological and behavioural factors on adherence to swallowing exercises has not been adequately studied. This study aims to develop and test the feasibility of a Swallowing intervention Package (SiP) designed in partnership with patients, speech and language therapists (SLTs) and other members of the head and neck multi-disciplinary team (MDT), for patients undergoing chemoradiotherapy (CRT) or radiotherapy (RT) for head and neck cancer.

Methods/design

This feasibility study uses quantitative and qualitative research methods, within a quasi-experimental design, to assess whether patients will tolerate and adhere to the SiP intervention, which aspects of the intervention can be implemented and which cannot, whether treatment fidelity can be achieved across different contexts, whether study processes and outcome measures will be feasible and acceptable and to what extent the intervention is likely to have an impact on swallowing dysfunction and quality of life. Patients are being recruited from five sites in Scotland and England (three interventions and two usual care). The SLT based in the relevant intervention centre teaches the exercise programme and provides supporting materials. A combination of patient-reported outcome measures (PROMs), adherence measures and clinical swallowing assessments are used prior to intervention (baseline), at the end of treatment, 3 and 6 months post-treatment.

Discussion

This collaborative study has taken a unique approach to the development of a patient-centred and evidence-based swallowing intervention. The introduction of an e-SiP app provides an exploration of the use of technology in delivering this intervention. The study provides an opportunity to examine the feasibility of delivering and participating in a supported swallowing intervention across several different NHS sites and will provide the evidence needed to refine intervention and study processes for a future trial.

The need for supportive care among head and neck cancer patients: psychometric assessment of the Dutch version of the Supportive Care Needs Survey Short-Form (SCNS-SF34) and the newly developed head and neck cancer module (SCNS-HNC)

Purpose

The purpose of this study is to assess the psychometric properties of the Dutch version of the 34-item Short-Form Supportive Care Needs Survey (SCNS-SF34) and the newly developed module for head and neck cancer (HNC) patients (SCNS-HNC).

Methods

HNC patients were included from two cross-sectional studies. Content validity of the SCNS-HNC was analysed by examining redundancy and completeness of items. Factor structure was assessed using confirmatory and exploratory factor analyses. Cronbach’s alpha, Spearman’s correlation, Mann–Whitney U test, Kruskall–Wallis and intraclass correlation coefficients (ICC) were used to assess internal consistency, construct validity and test–retest reliability.

Results

Content validity of the SCNS-HNC was good, although some HNC topics were missing. For the SCNS-SF34, a four-factor structure was found, namely physical and daily living, psychological, sexuality and health system and information and patient support (alpha = .79 to .95). For the SCNS-HNC, a two-factor structure was found, namely HNC-specific functioning and lifestyle (alpha = .89 and .60). Respectively, 96 and 89 % of the hypothesised correlations between the SCNS-SF34 or SCNS-HNC and other patient-reported outcome measures were found; 57 and 67 % also showed the hypothesised magnitude of correlation. The SCNS-SF34 domains discriminated between treatment procedure (physical and daily living p = .02 and psychological p = .01) and time since treatment (health system, information and patient support p = .02). Test–retest reliability of SCNS-SF34 domains and HNC-specific functioning domain was above .70 (ICC = .74 to .83), and ICC = .67 for the lifestyle domain. Floor effects ranged from 21.1 to 70.9 %.

Conclusions

The SCNS-SF34 and SCNS-HNC are valid and reliable instruments to evaluate the need for supportive care among (Dutch) HNC patients.

Low level laser therapy/photobiomodulation in the management of side effects of chemoradiation therapy in head and neck cancer: part 1: mechanisms of action, dosimetric, and safety considerations

PURPOSE

There is a large body of evidence supporting the efficacy of low level laser therapy (LLLT), more recently termed photobiomodulation (PBM), for the management of oral mucositis (OM) in patients undergoing radiotherapy for head and neck cancer (HNC). Recent advances in PBM technology, together with a better understanding of mechanisms involved, may expand the applications for PBM in the management of other complications associated with HNC treatment. This article (part 1) describes PBM mechanisms of action, dosimetry, and safety aspects and, in doing so, provides a basis for a companion paper (part 2) which describes the potential breadth of potential applications of PBM in the management of side-effects of (chemo)radiation therapy in patients being treated for HNC and proposes PBM parameters.

METHODS

This study is a narrative non-systematic review.

RESULTS

We review PBM mechanisms of action and dosimetric considerations. Virtually, all conditions modulated by PBM (e.g., ulceration, inflammation, lymphedema, pain, fibrosis, neurological and muscular injury) are thought to be involved in the pathogenesis of (chemo)radiation therapy-induced complications in patients treated for HNC. The impact of PBM on tumor behavior and tumor response to treatment has been insufficiently studied. In vitro studies assessing the effect of PBM on tumor cells report conflicting results, perhaps attributable to inconsistencies of PBM power and dose. Nonetheless, the biological bases for the broad clinical activities ascribed to PBM have also been noted to be similar to those activities and pathways associated with negative tumor behaviors and impeded response to treatment. While there are no anecdotal descriptions of poor tumor outcomes in patients treated with PBM, confirming its neutrality with respect to cancer responsiveness is a critical priority.

CONCLUSION

Based on its therapeutic effects, PBM may have utility in a broad range of oral, oropharyngeal, facial, and neck complications of HNC treatment. Although evidence suggests that PBM using LLLT is safe in HNC patients, more research is imperative and vigilance remains warranted to detect any potential adverse effects of PBM on cancer treatment outcomes and survival.
