Palliative intent treatment for head and neck cancer: an analysis of practice and outcomes

Radiation Therapy Oncology Group 8502 "QUAD shot" regimen using volumetric modulated arc therapy for incurable head and neck cancer

OBJECTIVES

We aimed to evaluate the outcomes of the Radiation Therapy Oncology Group 8502 "QUAD shot" regimen using volumetric modulated arc therapy (VMAT) for incurable head and neck cancer (HNC).

MATERIALS AND METHODS

We included 105 patients with HNC in the study, undergoing at least one QUAD shot regimen cycle. We planned the radiotherapy using VMAT with 6 MV photons. One QUAD shot cycle included 14.8 Gy in 4 fractions with at least 6-hour intervals over 2 consecutive days, repeated every 3-6 weeks up to 3 cycles.

RESULTS

We completed 1, 2, and 3 cycles in 11 (10 %), 17 (16 %), and 77 (73 %) patients, respectively. We concurrently performed systemic therapy in 13 (12 %) patients. Tumor response was observed in 92 (88 %) patients and at least one symptom relief in 51 (71 %) of 72 patients. We observed an overall response (tumor response or symptom relief) in 98 (93 %) patients with all patients who completed 3 cycles achieving it. The median overall survival (OS) was 6.8 months. Our multivariate analysis revealed that non-squamous cell carcinoma (p < 0.001), T category of 0-2 (p = 0.021), and 3 QUAD shot cycles (p < 0.001) were independent prognostic factors of better OS. We observed Grade 3 toxicity in 2 (2 %) patients while no ≥ Grade 4 acute or ≥ Grade 3 late toxicity.

CONCLUSIONS

The QUAD shot regimen using VMAT exerts appropriate palliative effect in patients with incurable HNC. Treatment with higher QUAD shot cycle number would be recommended for better treatment outcomes.

Treatment priorities and regret in older adults with head and neck cancer: A systematic review

BACKGROUND

The majority of head and neck cancer (HNC) diagnoses are seen in people aged 70 and older; these numbers are set to increase. Greater understanding of treatment needs of older patients with HNC is essential. These older patients often have co-existing health conditions, are prone to frailty and may not prioritise survival when considering treatment options. This systematic review examines the current research with regard to priorities and factors influencing treatment regret in older people with HNC.

METHODS

Studies were eligible for inclusion if they (i) reported data from patients with a mean age of 65 years or older who had a confirmed diagnosis of HNC and had been treated using surgery, chemotherapy and/or radiotherapy with either palliative or curative intent, (ii) considered patient's priorities or preferences or examined treatment regret as one of the primary outcomes of the study (iii) were published in English.

RESULTS

Pilot search identified n = 7222 articles; however, following screening, only four papers met the inclusion criteria. Narrative synthesis was indicated to analyse quantitative and qualitative evidence in parallel, as meta-analyses were not possible.

DISCUSSION

There is a paucity in the literature examining older adults with HNC. There is an indication that older adults prioritise maintaining independence when making treatment decisions and treatment regret is seen in those with high levels of depression with level of frailty also a contributing factor. Clinicians should consider patient's social circumstances, premorbid status and priorities in maintaining independence and managing symptoms when making treatment decisions in this cohort.

Understanding the challenges and need for support of informal caregivers to individuals with head and neck cancer - A basis for developing internet-based support

PURPOSE

Being an informal caregiver of an individual with head and neck cancer can be demanding. Still, informal caregivers can provide valuable support to patients throughout the disease trajectory. The aim of this study was to explore informal caregivers' views on their challenges and needs in attaining high preparedness for caregiving.

METHODS

Fifteen informal caregivers of individuals with head- and neck cancer participated in a focus group discussion or an individual interview. Thematic analysis utilizing an inductive approach was performed.

RESULTS

The results describe the challenges that informal caregivers to individuals with head and neck cancer perceive and their needs for support in preparedness for caregiving. Three main themes were found: Challenges of being an informal caregiver, Transformation in life and Informal caregiver' needs of support and sharing care.

CONCLUSION

This study contributes to the understanding of the challenges for informal caregivers to individuals with head and neck cancer in increasing preparedness for caregiving. To improve preparedness for caregiving, informal caregivers need education, information and support regarding physical, psychological and social issues for individuals with head and neck cancer.

Learnings From Longitudinal Patient-Reported and Clinical Outcomes in Palliative Head and Neck Cancer Care

OBJECTIVE

Patients with palliative head and neck cancer experience many symptoms in a short period of time. Longitudinal data on patient-reported outcomes in this phase are lacking. The aim of this study is to use structurally obtained patient-reported outcome data combined with clinical patient data and obtain insight in patient-reported outcomes, survival, circumstances of death, and interventions and treatment during the palliative phase in order to improve the quality of end-of-life care and patient-centered counseling.

STUDY DESIGN

Longitudinal observational cohort study.

SETTING

Tertiary cancer center.

METHOD

Quality of life was prospectively collected using the European Organization for Research and Treatment of Cancer QLQ-C15-PAL. Tumor- and patient-specific data were retrospectively collected. Descriptive statistics, linear mixed models, and regression analyses were performed.

RESULTS

A significant deterioration was found in global health status, physical functioning, fatigue, dyspnea, appetite loss, and constipation over time. However, emotional functioning improved. Median survival was 5.1 months, and only a low percentage of in-hospital death was observed (7.8%). Higher global health status at intake was associated with prolonged survival.

CONCLUSION

Structural measurement of patient-reported outcome together with clinical outcomes provides unique insight, which enables improvement of patient-centered counseling and care.

Palliative care management of head and neck cancer patients among otolaryngology surgeons: a novel national survey assessing knowledge, decision making, perceived confidence and training in the UK

Objective

Management of head and neck cancer patients provides unique challenges. Palliation serves to optimise quality-of-life by alleviating suffering and maintaining dignity. Prompt recognition and management of suffering is paramount to achieving this. This study aimed to assess perceived confidence, knowledge and adequacy of palliative training among UK-based otolaryngologists.

Method

Eight multiple-choice questions developed by five palliative care consultants via the Delphi method were distributed over five weeks. Knowledge, perceived confidence and palliative exposure among middle-grade and consultant otolaryngologists were assessed, alongside training deficits.

Results

Overall, 145 responses were collated from middle-grade (n = 88, 60.7 per cent) and consultant (n = 57, 39.3 per cent) otolaryngologists. The mean knowledge score was 5 out of 10, with 22.1 per cent (n = 32) stating confidence in palliative management. The overwhelming majority (n = 129, 88.9 per cent) advocated further training.

Conclusion

A broad understanding of palliative care, alongside appropriate specialist involvement, is key in meeting the clinical needs of palliative patients. Curriculum integration of educational modalities such as simulation and online training may optimise palliative care.

Palliation of head and neck cancer: a review of the unique difficulties

Each year, there are 11 900 new diagnoses of head and neck cancers in the UK, with around 4000 deaths. Survival rates are higher for those diagnosed earlier, however, patients are often diagnosed later, with 20% palliative at the time of diagnosis. There is a scarcity of head and neck cancer palliative care literature available. This review article aims to discuss the unique challenges of head and neck cancer palliation. It specifically focusses on the challenges of pain management, airway obstruction, dysphagia, haemorrhage and the psychology of palliative head and neck cancer management. This article explores the advantages and disadvantages of many of the different treatment options available. It is hoped that this article will highlight the unique difficulties encountered by patients with head and neck cancer towards the end of their life and offer insights and suggestions to improve patients' quality of life in their final weeks and months.

Association between palliative care referral and burden of illness among cancers of the lip, oral cavity and pharynx

PURPOSE

To evaluate the burden of illness--length of stay (LOS), total charges, and discharge disposition--among cancers of the lip, oral cavity and pharynx (CLOP) patients with and without palliative care (PC) referral.

METHODS

This cross-sectional study utilized the 2017 National inpatient sample database to identify hospitalizations with a primary diagnosis of CLOP. Generalized linear models were used to assess the association between PC referral status and the outcomes-LOS, total charges, and discharge disposition while controlling for patients' characteristics.

RESULTS

There were 4165 PC referral among 52, 524 CLOP patients. The geometric mean of LOS for non-PC referral patients was 3.7 days, and for PC referral was 5.02 days, P < 0.001. In the adjusted analysis, CLOP patients with PC referral were more likely to have a higher LOS (Coefficient: 1.16; 95% CI, 1.01-1.25) compared to those without PC referral. The geometric mean of total charge among non-PC referral group was 48,308 USD, and CLOP-PC referral was 48,983 USD, P = 0.72. After adjusting for covariates, there was still no significant difference between the PC and non-PC referral groups. Discharge disposition were considerably different across the non-PC vs. PC referral groups. Compared to non-PC referral patients, PC referral patients were more likely to be discharge to skilled nursing facility, intermediate care, and another type of facility (aOR = 7.10; CIs, 5.51-9.12), or home health care (aOR = 4.13; CIs, 3.31-5.15).

CONCLUSION

During primary hospitalization, total charges was not different between patient non-PC and PC referral groups; however, the LOS and discharge dispositions were significantly different.

The unmet needs of patients with advanced incurable head and neck cancer and their carers: A systematic review and meta-ethnography of qualitative data

INTRODUCTION

Patients with advanced-stage head and neck cancers (HNC) endure a significant symptom burden and suffer greatly towards the end of their lives. Qualitative evidence can provide insight into how existing services meet their needs. We aimed to synthesise qualitative data from patients with advanced HNC and their carers to inform improvements to services and care.

METHODS

A systematic search was conducted in MEDLINE and EMBASE for studies containing qualitative data from patients with advanced HNC and their carers. An interpretive account was generated using the meta-ethnography methodology.

RESULTS

We identified 8 studies including 38 patients and 25 carers. Twenty-six themes were synthesised into five concepts: psychological impact and adjustment, physical limitations and deliverance of symptomatic care, communication and information needs from healthcare professionals, social support and dependence, and needs of the primary caregiver. We identified that patients had complex psychological needs, centred on uncertainty and fear of suffering. Patients desired full information and found poor communication highly distressing. There was a dearth of literature on the subjective impact of physical limitations. Patients became reliant on social networks, and those with lower quality relationships coped poorly. However, caregivers struggled to meet patients' complex needs, resulting in distress and isolation.

CONCLUSIONS

Patients with advanced HNCs have complex needs that are not met in current systems. Further qualitative work focusing on the physical and psychological impact of advanced HNC would be of value.

Palliative care in metastatic head and neck cancer

BACKGROUND

Due to inherent impact on quality of life, metastatic head and neck cancer patients are well-suited to benefit from palliative care (PC). Our objective was to examine factors that shape PC utilization and implications for overall survival in stage IVc head and neck cancer patients.

METHODS

A retrospective study of patients with stage IVc head and neck cancer in the National Cancer Database from 2004 and 2015 was conducted.

RESULTS

7794 cases met inclusion criteria, of which 19.3% received PC. PC use was associated with more recent years of diagnosis, Northeast facility geography, and non-private insurances (p < 0.05). Compared to no PC, "interventional" PC, defined as palliative surgery, radiation, and/or chemotherapy, and "pain management only" PC were associated with lower overall survival (p < 0.05).

CONCLUSIONS

PC use increased over time and was associated with demographic and clinical factors. There remains opportunity for improvement in optimal implementation of palliative care.

Associations of insurance, urbanity, and comorbidity with types of palliative care received by patients with head and neck cancer

BACKGROUND

Our study examined some of the social and medical factors associated with receiving pain palliation alone over more aggressive cytoreductive palliative measures, such as surgery, chemotherapy, or radiation among patients with head and neck cancer.

METHODS

This retrospective study used the National Cancer Database 2016 for data analysis. Patient and tumor characteristics were examined using bivariate analysis and logistic regression to identify their association with receiving pain palliation alone versus cytoreductive palliation treatment.

RESULTS

Using multivariate logistic regression analysis, insurance status (odds ratio [OR]: 0.27, 95% confidence interval [CI]: 0.15-0.50, p < 0.001), urbanity (OR: 1.73, 95%CI: 1.21-2.46, p = 0.002), and Charlson-Deyo scores greater than 3 (OR: 2.49, 95%CI: 1.38-4.47, p = 0.002) were significantly associated with receipt of pain palliation alone.

CONCLUSIONS

Clinicians should be aware of non-health-related factors, such as insurance status, that may influence patients' receipt of treatments in head and neck cancer.

A Nordic survey of the management of palliative care in patients with head and neck cancer

BACKGROUND

The five Nordic countries with a population of 27M people form a rather homogenous region in terms of health care. The management of Head and Neck Cancer (HNC) is centralized to the 21 university hospitals in these countries. Our aim was to survey the current status of organization of palliative care for patients with HNC in the Nordic countries as the field is rapidly developing.

MATERIALS AND METHODS

A structured web-based questionnaire was sent to all the Departments of Otorhinolaryngology-Head and Neck Surgery and Oncology managing HNC in the Nordic countries.

RESULTS

All 21 (100%) Nordic university hospitals responded to the survey. A majority (over 90%) of the patients are discussed at diagnosis in a multidisciplinary tumor board (MDT), but the presence of a palliative care specialist is lacking in 95% of these MDT's. The patients have access to specialized palliative care units (n = 14, 67%), teams (n = 10, 48%), and consultants (n = 4, 19%) in the majority of the hospitals.

CONCLUSION

The present results show that specialized palliative care services are available at the Nordic university hospitals. A major finding was that the collaboration between head and neck surgeons, oncologists and palliative care specialists is not well structured and the palliative care pathway of patients with HNC is not systematically organized. We suggest that early integrated palliative care needs to be included as an addition to the already existing HNC care pathways in the Nordic countries.

Hypofractionated palliative volumetric modulated arc radiotherapy with the Radiation Oncology Study Group 8502 "QUAD shot" regimen for incurable head and neck cancer

BACKGROUND

To review a single institutional experience of the Radiation Therapy Oncology Group (RTOG) 8502 "QUAD shot" regimen using volumetric modulated arc radiotherapy (VMAT) for incurable head and neck cancer (HNC).

METHODS

Thirty-four consecutive patients with HNC were treated with at least one cycle of the RTOG 8502 regimen. Treatment plans included the use of VMAT with 6 MV photons generated by a linear accelerator. Two daily fractions of 3.7 Gy were delivered with an interval of at least 6 h for 2 consecutive days, totaling 14.8 Gy over 4 fractions. This was repeated every 3-4 weeks for a total of three cycles. No concurrent systemic therapy was performed.

RESULTS

The number of completed cycles was 1 in 6 (18%) patients, 2 in 5 (15%), and 3 in 23 (68%). Tumor response was achieved in 29 (85%) patients and symptom relief in 20 (77%) of 26 patients. Overall response (tumor response or symptom relief) was achieved in 32 (94%) patients. All patients who received 2 or more treatment cycles achieved overall response. Median overall survival (OS) was 5.7 months. Multivariate analysis revealed that completion of all three treatment cycles was significantly associated with better OS (P = 0.002). Grade 2 toxicity was observed in four (12%) patients, but no acute Grade ≥ 3 or late toxicity was observed.

CONCLUSIONS

The RTOG 8502 "QUAD shot" regimen using VMAT is effective for incurable HNC with highly reduced toxicity. Treatment with multiple cycles is recommended for better treatment response and/or survival.

Disease trajectories, place and mode of death in people with head and neck cancer: Findings from the 'Head and Neck 5000' population-based prospective clinical cohort study

BACKGROUND

Few large studies describe initial disease trajectories and subsequent mortality in people with head and neck cancer. This is a necessary first step to identify the need for palliative care and associated services.

AIM

To analyse data from the Head and Neck 5000 study to present mortality, place and mode of death within 12 months of diagnosis.

DESIGN

Prospective cohort study.

PARTICIPANTS

In total, 5402 people with a new diagnosis of head and neck cancer were recruited from 76 cancer centres in the United Kingdom between April 2011 and December 2014.

RESULTS

Initially, 161/5402 (3%) and 5241/5402 (97%) of participants were treated with 'non-curative' and 'curative' intent, respectively. Within 12 months, 109/161 (68%) in the 'non-curative' group died compared with 482/5241 (9%) in the 'curative' group. Catastrophic bleed was the terminal event for 10.4% and 9.8% of people in 'non-curative' and 'curative' groups, respectively; terminal airway obstruction was recorded for 7.5% and 6.3% of people in the same corresponding groups. Similar proportions of people in both groups died in a hospice (22.9% 'non-curative'; 23.5% 'curative') and 45.7% of the 'curative' group died in hospital.

CONCLUSION

In addition to those with incurable head and neck cancer, there is a small but significant 'curative' subgroup of people who may have palliative needs shortly following diagnosis. Given the high mortality, risk of acute catastrophic event and frequent hospital death, clarifying the level and timing of palliative care services engagement would help provide assurance as to whether palliative care needs are being met.
