Advances in Supportive Care for Late Effects of Head and Neck Cancer

Case-control study of oral disease indexes in individuals with head and neck cancer after antineoplastic therapy

ABSTRACT Objective To evaluate the oral health of patients with head and neck cancer after antineoplastic treatment, and to compare them with patients with no history of cancer. Methods A total of 75 patients, divided into Study Group, composed of individuals after antineoplastic treatment (n=30), and Control Group, with individuals with no history of cancer (n=45), aged 37 to 79 years. The oral health status was evaluated through the index of decayed, missing or filled permanent teeth (DMFT), community periodontal index and evaluation of the use and need of prosthesis. All of these items were evaluated according to the criteria recommended by the World Health Organization. The statistical analysis was descriptive and used the Pearson’s χ2 test. Results The community periodontal index was higher in the Study Group when compared to the Control Group (p<0.0001). The need for an upper (p<0.001) and lower (p<0.0001) prostheses was higher in the Study Group. Also, the use of upper prosthesis was higher in the Study Group (p<0.002). The missing or filled permanent teeth index between the two groups (p>0.0506) and the use of lower prosthesis (p>0.214) did not present a relevant statistical difference. Conclusion Periodontal disease and edentulism are the most significant changes in individuals who received antineoplastic therapy for head and neck cancer as well as greater need for oral rehabilitation.

Self-expression and identity after total laryngectomy: Implications for support

OBJECTIVE

To explore how individuals with a laryngectomy (IWL) from diverse backgrounds make meaning and adjust to the physical and functional changes from a total laryngectomy. To examine the extent primary supporters (PS) and health professionals (HP) are able to support IWL with the psychosocial and existential challenges rendered by a surgery that significantly impacts a person's talking, breathing, swallowing, and appearance.

METHODS

A constructivist grounded theory approach and symbolic interactionism were used to guide data collection and analysis. Semi-structured interviewing occurred.

RESULTS

Twenty-eight participants (12 IWL, 9 PS, and 7 HP) were interviewed. The findings suggest that IWL experience significant change to their self-identity and there is evidence of a range of passive and active reframing patterns (destabilised, resigned, resolute, and transformed). The loss of self-expression included changes to communicative participation, personal style, food preferences, and social roles. Short and longer-term supports appear to influence outcomes but are often ill-equipped to manage the psychosocial needs of IWL.

CONCLUSIONS

Loss of self-expression after total laryngectomy influences self-identity and adjustment. How individuals reframe their identity appears to be tied with how they view their disabilities and disfigurement. These perceptions also appear to be influenced by the reactions of others and the support available. Further resourcing, education, and training are needed so that PS and HP can provide holistic care.

Consensus and clinical recommendations for nutritional intervention for head and neck cancer patients undergoing chemoradiotherapy in Taiwan

Because of the anatomical location, patients with head and neck cancer (HNC) frequently experience dysphagia and malnutrition at the time of diagnosis and these conditions are often exacerbated after chemoradiotherapy. There is an emerging medical need to establish a consensus on nutritional intervention for these patients. A panel of 30 senior physicians and experts from multidisciplinary teams drafted clinical recommendations to improve the management of nutritional interventions in Taiwan and to provide updated treatment strategy recommendations in hope of improving the nutritional status of patients with HNC. This clinical review describes the resulting consensus document, including the impact of malnutrition on clinical outcomes, the role of prophylactic tube feeding, the choice of tube feeding, and the benefit of oral nutritional supplements in patients with HNC undergoing chemoradiotherapy. The outcomes of this review will support clinicians in their efforts to improve the nutritional status of patients with HNC.

Dual delivery of hydrophilic and hydrophobic drugs from chitosan/diatomaceous earth composite membranes

Oral administration of drugs presents important limitations, which are frequently not granted the importance that they really have. For instance, hepatic metabolism means an important drug loss, while some patients have their ability to swell highly compromised (i.e. unconsciousness, cancer…). Sublingual placement of an accurate Pharmaceutical Dosage Form is an attractive alternative. This work explores the use of the β-chitosan membranes, from marine industry residues, composed with marine sediments for dual sublingual drug delivery. As proof of concept, the membranes were loaded with a hydrophilic (gentamicin) and a hydrophobic (dexamethasone) drug. The physico-chemical and morphological characterization indicated the successful incorporated of diatomaceous earth within the chitosan membranes. Drug delivery studies showed the potential of all formulations for the immediate release of hydrophilic drugs, while diatomaceous earth improved the loading and release of the hydrophobic drug. These results highlight the interest of the herein developed membranes for dual drug delivery.

Survivorship Care Planning and Quality of Life

Roughly 436,000 survivors are living with a history of head and neck cancer (HNC), accounting for approximately 3% of all cancer survivors in the United States [1, 2]. With advances in treatment, long-term survival is increasingly common in HNC populations. Despite increasing awareness of survivorship issues, many challenges remain. These include lack of knowledge on late and long-term effects of treatment, and poor integration of survivorship care guidelines into oncology practice. Survivorship care plans (SCPs) are increasingly important for HNC survivors to improve quality of long-term survival. Quality survivorship care should focus on management of late and long-term effects of treatment, surveillance for cancer recurrence and second primaries, promotion of healthy lifestyle, and care coordination between providers. This chapter will describe common quality of life (QOL) issues in HNC survivorship, and review the current survivorship care guidelines in HNC.

The Impact on Resource Utilization of Supportive Care Consults on Patients at the University of North Carolina Hospital, 2010-2012

BACKGROUND

Cancer patients have a high rate of emergency department (ED) visits and inpatient hospitalizations (IHs) that may be reduced by use of outpatient palliative care services.

OBJECTIVE

To determine whether the outpatient adult palliative care service at the University of North Carolina (UNC) Hospital, begun in 2008, reduced the frequency of ED visits and IH during a two-year period.

DESIGN

The charts of patients with lung cancer or head and neck cancer seen by the supportive care service from 2010 to 2011, and of a contemporaneous set of potential consults that were not seen, were retrospectively reviewed to determine the impact of this care delivery model.

SETTING/SUBJECTS

The number of individuals with lung cancer and head cancer seen during this two-year period was 24 and 23, respectively, permitting a statistical analysis from which meaningful conclusions could be drawn.

MEASUREMENTS

The frequency of ED visits and IHs for each patient was reviewed. Descriptive statistics were used. Fisher's exact test was used for data categorized into two by two contingency tables. The nonparametric Jonckheere-Terpstra method was used to test for ordered differences across categories.

RESULTS

Consultation with supportive care did not decrease overall use of ED visits. Patients with head and neck cancer showed an increase in ED visits (p = 0.08) but a reduction in inpatient admissions (p = 0.0004). In patients with lung cancer, the opposite effect was seen-an increase in inpatient visits (p = 0.02) but a decrease in ED visits. The frequency of ED visits was correlated with distance to the ED (p = 0.02), a finding that has not been noted before.

CONCLUSIONS

Further work is needed to define the best model for outpatient palliative care.

Evaluation of bond strength of a conventional adhesive system in irradiated teeth

Abstract Introduction One of the most common treatments of head and neck cancer patients is radiotherapy, a treatment method which uses ionizing radiation beam and destroys tumor cells, minimizing damage to neighbor cells. Purpose To evaluate the bond strength of a conventional adhesive system in irradiated teeth. Method 24 third human molars, 12 of which were randomly exposed to radiation and prepared from the removal of occlusal enamel, then exposed to a flat dentine surface. The adhesive system Stae was applied according to the manufacturer’s instructions. Next, two 2 mm increments of resin were implemented. The samples were hemi sectioned specimens, originating shapped toothpick. To evaluate the bond strength, a micro tensile test was done with 500N load and speed of 0.5 mm/minute. Result There was no statistically significant difference between the bond strength of teeth which were or were not exposed to radiation and which used a conventional adhesive system. Conclusion Although the radiation doses applied may cause some alterations in microscopic range in dental tissues, it can be concluded that these alterations do not influence in the bond strength in dentin of irradiated teeth.

Survivorship of patients with head and neck cancer receiving care in a tertiary health facility in Nigeria

Background

Head and neck cancer (HNC) is a major clinical and public health concern worldwide which impairs the vital functions of life. The treatment of metastatic HNCs is mainly palliative. This study examined the survival patterns and treatment outcomes in patients with HNCs in a tertiary hospital in Nigeria.

Materials and methods

A review of the case files and treatment cards of patients with histological diagnosis of HNCs seen between January 2002 and December 2011 at the Radiotherapy Department, University College Hospital, Ibadan, was conducted. A total of 494 cases were identified, of which 481 had valid records. Analyses were done using Kaplan–Meier survival function and Cox proportional hazard regression techniques at 5% significance level.

Results

The median age of patients was 42 years with a male-to-female ratio of 2:1. Most patients presented at stages 3 (50.7%) and 4 (36.8%). Nasopharyngeal carcinoma was the most common (42.6%) HNC, followed by paranasal sinus (17.7%) and laryngeal cancer (11.6%). The lung was the most common site of metastasis (25.5%). Patients who presented at stages 1 and 4 disease had a median survival of 7.8 years and 1.9 years, respectively. Patients treated with a combination of chemotherapy and radiotherapy had a median survival of 8.0 years compared with those who had a single modality of treatment (~6.3 years).

Conclusion

Patient survival was inversely proportional to the stage of the disease. To encourage the early presentation of HNC cases, health education of the population on routine medical check-ups and on the symptoms suggestive of HNC is recommended. Health care providers should be trained to refer suspected cases promptly to tertiary health facilities for management.

Development of a survivorship needs assessment planning tool for head and neck cancer survivors and their caregivers: a preliminary study

PURPOSE

The purpose of this study was to characterize primary end-of-treatment challenges in head and neck cancer (HNC) to drive the development of a survivorship needs assessment planning (SNAP) tool and evaluate its acceptability and feasibility.

METHODS

Using qualitative methods (focus groups, interviews), we identified physical, emotional, and social post-treatment challenges from the perspectives of survivors (N = 17), caregivers (N = 14), and healthcare providers (N = 14) and pretested the SNAP tool. After Advisory Board ratings and consensus, the tool was finalized.

RESULTS

Survivors, caregivers and clinicians consistently highlighted the importance of assessing symptoms and functional abilities (e.g., dry mouth, speech/swallowing difficulties, weight loss), health behaviors (e.g., smoking, alcohol), emotional concerns (e.g., depression, isolation, nutritional distress), and social challenges (e.g., support, finances). Caregivers were overwhelmed and intensely focused on survivors' nutrition and trach/feeding tube care while clinicians emphasized financial and access concerns. Most participants were enthusiastic about the tool and directed a flexible care plan design due to variability in dyad needs. Over 75% reported high comfort using and navigating questions on a tablet and were in strong agreement that the care plan would help families practically and emotionally. Coordination of survivorship visits with follow-up care was critical to address travel and time barriers. While survivors and clinicians recommended waiting 1-6 months after treatment, caregivers preferred earlier survivorship visits.

CONCLUSIONS

Results pinpointed optimal end-of-treatment domains for routine assessment and support the feasibility of implementing a SNAP tool in the clinic.

IMPLICATIONS FOR CANCER SURVIVORS

Capitalizing on technology to direct HNC survivorship care is promising.

Feasibility of tongue strength measurements during (chemo)radiotherapy in head and neck cancer patients

PURPOSE

The aim of this study was to investigate the feasibility of tongue strength measures (TSMs) and the influence of bulb location, sex, and self-perceived pain and mucositis in head and neck cancer (HNC) patients during chemoradiotherapy (CRT).

METHODS

Twenty-six newly diagnosed HNC patients treated with CRT performed anterior and posterior maximal isometric tongue pressures by means of the Iowa Oral Performance Instrument (IOPI). The Oral Mucositis Weekly Questionnaire (OMWQ) and a Visual Analogue Scale (VAS) for pain during swallowing were completed weekly from baseline to 1 week post CRT.

RESULTS

Feasibility of TSMs during CRT declines significantly from 96 to 100% at baseline to 46% after 6 weeks of CRT. But post-hoc analyses reveal only significant differences in feasibility between baseline and measurements after 4 weeks of treatment. No effect of gender or bulb location was established, but feasibility is influenced by pain and mucositis.

CONCLUSIONS

Feasibility of TSMs declines during CRT and is influenced by mucositis and pain. For the majority of subjects, TSMs were feasible within the first 4 weeks, which provides a window of scientific and clinical opportunities in this patient population.

Physical and emotional well-being and support in newly diagnosed head and neck cancer patient-caregiver dyads

The purpose of this study was to examine the physical and emotional well-being and social support in newly diagnosed head and neck cancer (HNC) patients and caregivers and identify sociodemographic, clinical, and behavioral risk factors associated with compromised well-being in patients and caregivers. Newly diagnosed HNC patients and their primary caregivers (N = 72 dyads) completed questionnaires before treatment assessing physical and mental well-being, depression, cancer worry, and open-ended support questions. Patients reported worse physical well-being than caregivers (p < 0.05) but similar levels of mental well-being. Caregivers reported providing emotional and instrumental support most frequently with an emphasis on nutrition and assistance with speech, appearance, and addictions. Both patients and their caregivers reported suboptimal mental well-being and depression. Smoking was associated with compromised well-being in patients, caregivers, and dyads. Compromised well-being in patients and their caregivers was more likely when patients were younger, had worse symptoms, and smoked/consumed alcohol (p < 0.05). While patients face more physical strain than caregivers, both equally confront emotional challenges. Results highlight risk factors for compromised well-being in both patients and their caregivers that should be assessed at diagnosis to guide identification of needed dyadic-focused supportive care resources.

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

CONTEXT

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSION

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

Supportive care for older people with frailty in hospital: An integrative review

BACKGROUND

Growing numbers of older people living with frailty and chronic health conditions are being referred to hospitals with acute care needs. Supportive care is a potentially highly relevant and clinically important approach which could bridge the practice gap between curative models of care and palliative care. However, future interventions need to be informed and underpinned by existing knowledge of supportive care.

AIM

To identify and build upon existing theories and evidence about supportive care, specifically in relation to the hospital care of older people with frailty, to inform future interventions and their evaluation.

DESIGN

An integrative review was used to identify and integrate theory and evidence. Electronic databases (Cochrane Medline, EMBASE and CIHAHL) were searched using the key term 'supportive care'. Screening identified studies employing qualitative and/or quantitative methods published between January 1990 and December 2015. Citation searches, reference checking and searches of the grey literature were also undertaken.

DATA SOURCES

Literature searches identified 2733 articles. After screening, and applying eligibility criteria based on relevance to the research question, studies were subject to methodological quality appraisal. Findings from included articles (n=52) were integrated using synthesis of themes.

RESULTS

Relevant evidence was identified across different research literatures, on clinical conditions and contexts. Seven distinct themes of the synthesis were identified, these were: Ensuring fundamental aspects of care are met, Communicating and connecting with the patient, Carer and family engagement, Building up a picture of the person and their circumstances, Decisions and advice about best care for the person, Enabling self-help and connection to wider support, and Supporting patients through transitions in care. A tentative integrative model of supportive care for frail older people is developed from the findings.

CONCLUSION

The findings and model developed here will inform future interventions and can help staff and hospital managers to develop appropriate strategies, staff training and resource allocation models to improve the quality of health care for older people.

Quality of life and functional status of terminally ill head and neck cancer patients: a nation-wide, prospective observational study at tertiary cancer centers in Japan

BACKGROUND

Little is known about quality of life and functional status of patients with terminally ill head and neck cancers.

METHODS

We conducted a multicenter, prospective, observational study to examine quality of life and functional status in terminally ill head and neck cancer patients.

RESULTS

Of the 100 patients meeting inclusion criteria, 72 were observed until death. There was no significant difference in the quality of life score between baseline and Week 3. Forty patients (54.9%) could speak and 22 patients (30.5%) could have oral intake upon study entry. Fifty-three patients (74.6%) received enteral nutrition. Twenty-six patients (36.6%) required dressing changes for fungating tumors. The route of nutritional intake (nasogastric tube vs. percutaneous gastric tube) might be predictive for the duration of hospital stay (64 vs. 21 days, P = 0.0372).

CONCLUSION

There was no significant relationship between quality of life and functional status seen in this study. Feeding tube type could have the most impact on quality of life.

Efficacy of Traditional Chinese Medicine in Xerostomia and Quality of Life during Radiotherapy for Head and Neck Cancer: A Prospective Pilot Study

Xerostomia is one of the most common acute and late complications of radiotherapy for head and neck cancer, and it affects quality of life. We conducted a prospective study to evaluate the efficacy of traditional Chinese medicine (TCM) in toxicities and quality of life during radiotherapy. Head and neck cancer patients who were scheduled for radiotherapy were checked for inclusion/exclusion criteria before enrollment. Patients in the study group (inpatients) were hospitalized in a Chinese medicine ward and received concomitant TCM intervention during radiotherapy, while those in the control group (outpatients) received only conventional cancer treatments at the Western outpatient department. The primary end point was amelioration of postradiotherapy side effects. The secondary end points were quality of life during the cancer therapy and occurrence of adverse events following the TCM treatments. Thirty inpatients and 50 outpatients completed the study. Compared to the control group, those in the TCM group had decreased severity of xerostomia. There was no treatment-related impairment of renal or hepatic function among TCM group. Although better outcomes of social contact, dyspnea, physical and emotional function, and financial problems were found in the TCM group, we need further confirmation about the impact of hospitalization itself on these results.

Locally advanced head and neck cancer in either the older or the vulnerable adult: Making the case for a team-based, "gero-centric" approach

Multidisciplinary, team-based care goes hand in hand with geriatric oncology paradigms for caring for older adults with cancer. Team-based care was the central theme for the 2015 SIOG Annual Meeting. Team-based approaches to the evaluation and management of older adults with different cancer types, including head and neck cancer, were presented. This review aims to summarize the salient points of that presentation, including a synthesis of recent multidisciplinary, "gero-centric" research efforts to improve the care for older adults with more advanced stages of head and neck cancer.

Dental Care for Survivors of Adolescent and Young Adult Cancer: Special Considerations

PURPOSE

Oral health is important for quality of life, but may be undermanaged for survivors of cancer. We examine dental care use and barriers among long-term survivors of adolescent and young adult (AYA) cancer in comparison to individuals without a history of cancer.

METHODS

The 2008-2012 Medical Expenditure Panel Survey (MEPS) identified 1216 individuals diagnosed with cancer at AYA ages (15-39 years), who were at least 5 years from diagnosis. A comparison group was matched using age, sex, and other factors. We evaluated self-reported dental visits in the previous 12 months, and inability and delay in receiving necessary dental care among survivors and the comparison group. Furthermore, individual factors associated with dental care use were identified using multivariable logistic regressions.

RESULTS

Of survivors, 60.86% reported no dental visits in the previous year compared to 51.96% of the comparison individuals (p < 0.001). Survivors were more likely to report inability (10.71% vs. 6.29%, p = 0.001) and delay (8.12% vs. 4.45%, p = 0.001) in getting necessary dental care than the comparison group. Notably, survivors without dental insurance were more likely to report inability and delay. Female survivors were more likely to use dental care than males (odds ratio = 1.76, 95% confidence interval 1.15-2.71, p = 0.01). Hispanic survivors, those diagnosed at younger ages, and uninsured survivors were less likely to have at least one dental visit.

CONCLUSION

Survivors of AYA cancer need timely surveillance to manage late effects, including dental complications. Yet, these survivors, particularly those who are uninsured, delay dental care more often than individuals from the general population. Survivor-specific interventions are needed to reduce dental care barriers.
