Cancer and dementia: an exploratory study of the experience of cancer treatment in people with dementia

Good Death and Quality of End-of-Life Care in Patients with Coexisting Cancer and Dementia: Perspective of Bereaved Families

Background

Patients with coexisting cancer and dementia often have complex health care needs and face challenges in achieving a good death.

Objectives

To evaluate good death achievement and end-of-life (EOL) care in patients with coexisting cancer and dementia from the perspective of bereaved families.

Design

Cross-sectional nationwide postal survey.

Setting/Subjects

Bereaved families of patients with cancer who died in hospice and palliative care units across Japan.

Measurements

Bereaved families completed an anonymous, self-reported questionnaire. Their perspective on achieving a good death was assessed using the Good Death Inventory (GDI) (total score: 18-126). The Revised Care Evaluation Scale-short version (CES2) was used to assess EOL care (total score: 10-60). We examined the Brief Grief Questionnaire (BGQ) (total score: 0-10) and Patient Health Questionnaire 9 (PHQ9) (total score: 0-27).

Results

Data from 670 participants were analyzed, including 83 (12.4%) bereaved families of patients with coexisting cancer and dementia. No statistical differences were observed in the total GDI score for 18 items (dementia comorbidity vs. nondementia comorbidity groups, mean ± standard deviation, respectively, 78.4 ± 17.7 vs. 80.0 ± 15.5, adjusted [adj] P = 0.186), CES2 score (49.70 ± 9.22 vs. 48.82 ± 8.40, adj P = 0.316), BGQ score (3.40 ± 2.41 vs. 4.36 ± 2.28, adj P = 0.060), and PHQ9 score (4.67 ± 4.71 vs. 5.50 ± 5.37, adj P = 0.788).

Conclusions

GDI, CES2, BGQ, and PHQ9 scores did not differ significantly between groups, regardless of the presence of dementia in hospice and palliative care units. Patients with coexisting cancer and dementia can achieve a good death by high-quality EOL care.

Towards an improved dementia care experience in clinical radiography practice: A state-of-the-art review

INTRODUCTION

The increasing global incidence rate of dementia and associated co/multimorbidity has consequently led to a rise in the number of people with dementia (PwD) requiring clinical radiography care services. This review aims to explore and integrate findings from diverse settings with a focus on the experiences of PwD and stakeholders, towards the development of a holistic approach for dementia care and management within the context of radiography services.

METHOD

An electronic search was performed across the following databases: PUBMED, CINAHL, Medline, SCOPUS, and ScienceDirect for articles published from January 2009 and June 2023. Articles were included if they fulfilled a predefined criteria mainly focused on experiences of PwD and/or other stakeholders when using the radiography services. Data obtained from the included studies were analysed using a result-based convergent synthesis.

RESULT

Eleven studies from diverse settings met the inclusion criteria. A mix of both positive and negative experiences of PwD and stakeholders were reported following visits to radiology and radiotherapy departments were highlighted across settings. The findings were themed around the need for: person-centred care, effective communication, attitudinal changes of staff, specialised and improved clinical environment and inclusion of caregivers for the care of PwD.

DISCUSSION

This study emphasise the critical importance of adopting holistic approaches to caring for PwD. This involves adopting a person-centred approach, actively involving caregivers, effective communication, and adequate training for radiographers to provide quality services, all in dementia-friendly environments.

CONCLUSION

The experiences of various stakeholders highlight the need for a more holistic approach and strategy for the care and management of PwD within the context of the radiography services. This calls for an urgent need for a comprehensive strategy that includes awareness creation of staff to enhance the quality of care and the overall experience for PwD using the radiography services.

Factors Related to Person-Centered Care for Older Patients With Cancer and Dementia in Designated Cancer Hospitals

BACKGROUND

Person-centered care (PCC) should be promoted for patients with cancer and dementia who are likely to be hindered from pursuing a meaningful life owing to their will not being reflected in the cancer treatment process.

OBJECTIVE

This study aimed to clarify the factors related to nurses' practice of PCC for older patients with cancer and dementia in designated cancer hospitals.

METHODS

An online cross-sectional survey was administered to nurses working at designated cancer hospitals in Japan. The survey items included demographic data and factors assumed to be related to nursing practice and practice of PCC.

RESULTS

A multiple regression analysis indicated that the factors related to the practice of PCC were attitude toward patients with dementia (β = 0.264, P < .001), holding conferences (β = 0.255, P < .001), knowledge about cancer nursing (β = 0.168, P < .001), knowledge about dementia (β = 0.128, P = .003), and participation in dementia care training (β = 0.088, P = .032).

CONCLUSIONS

Nurses' practice of PCC may not be sufficient to provide personalized care tailored to patients' cognitive function. The factors related to PCC are attitude toward patients with dementia, holding conferences, knowledge about cancer and dementia, and dementia care training.

IMPLICATIONS FOR PRACTICE

To promote PCC for patients with cancer and dementia, nurses should learn about these conditions with an interest in patients and collaborate with other professionals. Future studies should use cluster sampling and focus on the extent of cancer or dementia symptoms.

S2k Guideline - Merkel cell carcinoma (MCC, neuroendocrine carcinoma of the skin) - Update 2022

Merkel cell carcinoma (MCC, ICD-O M8247/3) is a rare, malignant, primary skin tumor with epithelial and neuroendocrine differentiation. The tumor cells share many morphologic, immunohistochemical, and ultrastructural features with cutaneous Merkel cells. Nevertheless, the cell of origin of MCC is unclear. MCC appears clinically as a reddish to purple spherical tumor with a smooth, shiny surface and a soft to turgid, elastic consistency, usually showing rapid growth. Spontaneous and often complete regressions of the tumor are observed. These likely immunologically-mediated regressions explain the cases in which only lymph node or distant metastases are found at the time of initial diagnosis and why the tumor responds very well to immunomodulatory therapies even at advanced stages. Due to its aggressiveness, the usually given indication for sentinel lymph node biopsy, the indication of adjuvant therapies to be evaluated, as well as the complexity of the necessary diagnostics, clinical management should already be determined by an interdisciplinary tumor board at the time of initial diagnosis.

Understanding the experiences and psychosocial support needs of caregivers of people with comorbid dementia and cancer

BACKGROUND

Family carers of people living with comorbid dementia and cancer (CDC) play a vital supportive role, but this may be particularly burdensome and adversely impact their own health and wellbeing.

OBJECTIVE

To examine the experiences and psychosocial support needs of caregivers of people with CDC.

METHODS

A flyer advertising the study was distributed to relevant UK voluntary sector organisations and shared across social media. 13 carers of people with CDC were recruited. In-depth semi-structured interviews were conducted and transcripts were analysed using reflexive thematic analysis, underpinned by an inductive phenomenological approach.

RESULTS

Complex interactions of dementia and cancer resulted in heightened responsibility for carers, who played a crucial role in recognition/management of symptoms, performing difficult cancer-related care, and treatment decision-making that posed difficult ethical challenges. Care-recipients had reduced insight into their cancer diagnosis and prognosis, so carers often carried the emotional burden alone. Responsibilities faced by carers were compounded by a lack of targeted, accessible information/support for CDC. Carers expressed a desire to talk to and learn from others who understand the unique challenges of navigating cancer-related decision-making, treatment and care for people who are also living with dementia.

CONCLUSIONS

Cancer alongside dementia presents complex challenges for carers, who desire more cancer-related information and support which is tailored to people living with dementia and their family caregivers.

Cancer care for people with dementia: Literature overview and recommendations for practice and research

As many countries experience population aging, patients with cancer are becoming older and have more preexisting comorbidities, which include prevalent, age-related, chronic conditions such as dementia. People living with dementia (PLWD) are vulnerable to health disparities, and dementia has high potential to complicate and adversely affect care and outcomes across the cancer trajectory. This report offers an overview of dementia and its prevalence among patients with cancer and a summary of the research literature examining cancer care for PLWD. The reviewed research indicates that PLWD are more likely to have cancer diagnosed at an advanced stage, receive no or less extensive cancer treatment, and have poorer survival after a cancer diagnosis. These cancer disparities do not necessarily signify inappropriately later diagnosis or lower treatment of people with dementia as a group, and they are arguably less feasible and appropriate targets for care optimization. The reviewed research indicates that PLWD also have an increased risk of cancer-related emergency presentations, lower quality processes of cancer-related decision making, accessibility-related barriers to cancer investigations and treatment, higher experienced treatment burden and higher caregiver burden for families, and undertreated cancer-related pain. The authors propose that optimal cancer care for PLWD should focus on proactively minimizing these risk areas and thus must be highly person-centered, with holistic decision making, individualized reasonable adjustments to practice, and strong inclusion and support of family carers. Comprehensive recommendations are made for clinical practice and future research to help clinicians and providers deliver best and equitable cancer care for PLWD and their families.

Is there evidence of age bias in breast cancer health care professionals' treatment of older patients?

OBJECTIVES

Despite NICE (2009; 2018) guidelines to treat breast cancer patients 'irrespective of age', older women experience differential treatment and worse outcomes beyond that which can be explained by patient health or patient choice. Research has evidenced the prevalence of ageism and identified the role of implicit bias in reflecting and perhaps perpetuating disparities across society, including in healthcare. Yet age bias has rarely been considered as an explanatory factor in poorer outcomes for older breast cancer patients.

METHODS

This mixed methods study explored age bias amongst breast cancer HCPs through four components: 1) An implicit associations test (31 HCPs) 2) A treatment recommendations questionnaire (46 HCPs). 3) An attitudes about older patients questionnaire (31 HCPs). 4) A treatment recommendations interview (20 HCPs).

RESULTS

This study showed that breast cancer HCPs held negative implicit associations towards older women; HCPs were less likely to recommend surgery for older patients; some HCPs held assumptions that older patients are more afraid, less willing and able to be involved in decision-making, and are less willing and able to cope with being informed of a poor treatment prognosis; and conditions which disproportionately affect older patients, such as dementia, are not always well understood by breast cancer HCPs.

CONCLUSIONS

These results indicate that there are elements of age bias present amongst breast cancer HCPs. The study's findings of age-based assumptions and a poorer understanding of conditions which disproportionately affect older patients align with patterns of differential treatment towards older breast cancer patients suggesting that age bias may be, at least in part, driving differential treatment.

End-of-Life Costs of Cancer Patients With Alzheimer's Disease and Related Dementias in the U.S

CONTEXT

End-of-Life (EOL) care consumes a substantial amount of healthcare resources, especially among older persons with cancer. Having Alzheimer's Disease and Related Dementias (ADRD) brings additional complexities to these patients' EOL care.

OBJECTIVES

To examine the Medicare expenditures at the EOL (last 12 months of life) among beneficiaries having cancer and ADRD vs. those without ADRD.

METHODS

A retrospective cohort study used 2004-2016 Surveillance, Epidemiology, and End Results-Medicare data. Patient populations were deceased Medicare beneficiaries with cancer (breast, lung, colorectal, and prostate) and continuously enrolled for 12 months before death. Beneficiaries with ADRD were propensity score matched with non-ADRD counterparts. Generalized Estimating Equation Model was deployed to estimate monthly Medicare expenditures. Generalized Linear Models were constructed to assess total EOL expenditures.

RESULTS

Eighty six thousand three hundred ninety-six beneficiaries were included (43,198 beneficiaries with ADRD and 43,198 beneficiaries without ADRD). Beneficiaries with ADRD utilized $64,901 at the EOL, which was roughly $407 more than those without ADRD ($64,901 vs. $64,494, P = 0.31). Compared to beneficiaries without ADRD, those with ADRD had 11% higher monthly expenditure and 7% higher in total expenditures. Greater expenditure was incurred on inpatient (5%), skilled nursing facility (SNF) (119%), home health (42%), and hospice (44%) care.

CONCLUSION

Medicare spending at the EOL per beneficiary was not statistically different between cohorts. However, specific types of service (i.e., inpatient, SNF, home health, and hospice) were significantly higher in the ADRD group compared to their non-ADRD counterparts. This study underscored the potential financial burden and informed Medicare about allocation of resources at the EOL.

Caregiver experiences of making treatment decisions for older women with breast cancer and dementia

Family caregivers are an important source of support for older people living with dementia, especially when faced with a new diagnosis of cancer. Little is currently known about the caregiver role in facilitating treatment discussions, and the factors that underpin breast cancer treatment decision-making in older patients. This study used a sequential explanatory mixed method approach to explore the role of family caregivers in making cancer treatment decisions for older women (aged over 70 years) with pre-existing dementia and primary operable breast cancer. Thirteen caregivers participated in the study (13 completed a postal questionnaire; eight questionnaire respondents participated in a semi-structured interview). Quantitative data were analysed descriptively, and the Framework Approach was used to analyse qualitative findings and identify themes. Three themes were generated: (a) Clinical interactions, information and support; (b) Treatment decision-making processes and (c) Influences on treatment choice. These findings highlight the complexities that caregivers face when navigating cancer treatment options and their role in facilitating treatment decisions.

Evaluation of mild cognitive impairment and dementia in patients with metastatic renal cell carcinoma

BACKGROUND

Dementia and cancer are both more common in adults as they age. As new cancer treatments become more popular, it is important to consider how these treatments might affect older patients. This study evaluates metastatic renal cell carcinoma (mRCC) as a risk factor for older adults developing mild cognitive impairment or dementia (MCI/D) and the impact of mRCC-directed therapies on the development of MCI/D.

METHODS

We identified patients diagnosed with mRCC in a Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset from 2007 to 2015 and matched them to non-cancer controls. Exclusion criteria included age < 65 years at mRCC diagnosis and diagnosis of MCI/D within the year preceding mRCC diagnosis. The main outcome was time to incident MCI/D within one year of mRCC diagnosis for cases or cohort entry for non-cancer controls. Cox proportional hazards models were used to measure associations between mRCC and incident MCI/D as well as associations of oral anticancer agent (OAA) use with MCI/D development within the mRCC group.

RESULTS

Patients with mRCC (n = 2533) were matched to non-cancer controls (n = 7027). mRCC (hazard ratio [HR] 8.52, p < .001), being older (HR 1.05 per 1-year age increase, p < .001), and identifying as Black (HR 1.92, p = .047) were predictive of developing MCI/D. In addition, neither those initiating treatment with OAAs nor those who underwent nephrectomy were more likely to develop MCI/D.

CONCLUSIONS

Patients with mRCC were more likely to develop MCI/D than those without mRCC. The medical and surgical therapies evaluated were not associated with increased incidence of MCI/D. The increased incidence of MCI/D in older adults with mRCC may be the result of the pathology itself or risk factors common to the two disease processes.

Balancing the needs of individuals and services in cancer treatment for people with dementia: A focused ethnographic study

BACKGROUND

Managing multiple conditions is difficult for patients and their families, increasing complexity in care. Two of the most common long-term conditions, cancer and dementia, both disproportionately affect older adults. However, little is known about the needs and experiences of those living with both conditions, which could inform practice in the area.

OBJECTIVES

This focused ethnographic study sought to understand how oncology services balance the unique and complex needs of these patients with those of the service more widely.

DESIGN

Focused ethnography.

SETTING

Two National Health Service hospital trusts.

PARTICIPANTS

Seventeen people with dementia and cancer, 22 relatives and 19 staff members participated.

METHODS

Participant observation, informal conversations, semi-structured interviews, and medical notes review.

RESULTS

Improved satisfaction and outcomes of care were reported when staff were delivering person-centred care. Staff tried to balance the need for personalised and flexible support for individuals with dementia with managing targets and processes of cancer care and treatment. The importance of continuity of people, places, and processes was consistently highlighted.

CONCLUSION

Navigating and managing the delicate balance between the needs of the individual and the needs of services more widely was difficult for both staff and patients. Improved awareness, identification and documentation of dementia would help to ensure that staff are aware of any specific patient needs. Consistency in staffing and appointment locations should develop familiarity and routine for people with dementia.

Understanding and identifying ways to improve hospital-based cancer care and treatment for people with dementia: an ethnographic study

Background

Providing cancer care and treatment for ageing populations with complicating comorbidities like dementia is a growing global challenge. This study aimed to examine the hospital-based cancer care and treatment challenges and support needs of people with dementia, and identify potential ways to address these.

Methods

A two-site ethnographic study in England involving semi-structured interviews, observations and accompanying conversations, and medical record review. Participants (N = 58) were people with dementia and comorbid cancer (n = 17), informal caregivers (n = 22) and hospital staff (n = 19). Ethnographically informed thematic analysis was conducted.

Results

There was an accumulated complexity of living with both illnesses simultaneously. People with dementia and families could feel confused and uninformed due to difficulties understanding, retaining and using cancer information, which impacted their informed treatment decision-making. Dementia increased the complexity and burden of travelling to and navigating unfamiliar hospital environments, frequent lengthy periods of waiting in hospital, and self-managing symptoms and side-effects at home. Oncology staff were often working without the full picture, due to variable documenting of dementia in medical records, dementia training was limited, and time and resource pressures impeded the highly individualised, flexible cancer care required by people with dementia. Supportive family carers were crucial in enabling people with dementia to access, navigate and undergo cancer treatment and care.

Conclusions

Dementia complicates cancer care in a range of ways accumulating across the cancer pathway. Our findings suggest there are several strategies and interventions, which we list here, with potential to improve cancer care and treatment for people with dementia and their families.

Understanding the training and education needs of homecare workers supporting people with dementia and cancer: A systematic review of reviews

Many people with dementia, supported by family carers, prefer to live at home and may rely on homecare support services. People with dementia are also often living with multimorbidities, including cancer. The main risk factor for both cancer and dementia is age and the number of people living with dementia and cancer likely to rise. Upskilling the social care workforce to facilitate more complex care is central to national workforce strategies and challenges. Training and education development must also respond to the key requirements of a homecare workforce experiencing financial, recruitment and retention difficulties. This systematic review of reviews provides an overview of dementia and cancer training and education accessible to the homecare workforce. Findings reveal there is a diverse range of training and education available, with mixed evidence of effectiveness. Key barriers and facilitators to effective training and education are identified in order to inform future training, education and learning development for the homecare workforce supporting people with dementia and cancer.

Potential for identification of memory problems in the cancer clinic to enable improved treatment experience and outcomes: Mixed methods case study research

PURPOSE

To inform improvement in cancer treatment experience and outcomes for people with dementia or milder cognitive impairment. People with dementia, compared to those without, experience more side effects from cancer treatment and have poorer outcomes including poorer survival.

METHODS

The research was a mixed methods exploratory case study. Each case was a cancer treatment in a person with memory loss, a common symptom of dementia. Observations were conducted in 30 clinic sessions at one cancer centre between September 2014 and February 2015. Thirty-three encounters between people with a memory problem and a staff member were observed and ten consultations recorded. Interviews were conducted with five staff members and six people receiving cancer treatment, five accompanied by their carer. Analysis, informed by hermeneutic phenomenology, enabled the treatment pathway to be mapped and modelled to reveal sites for intervention.

FINDINGS

Five potential sites of intervention were identified in the treatment pathway. Five actions at the sites of intervention that may improve patient experience and outcomes include, raising awareness of common problems for people with cognitive impairment receiving cancer treatment, encouraging disclosure of memory problems, staff training to identify memory problems and to know what to do, offering tools and techniques to aid self-management of memory problems, and addressing carer support needs.

CONCLUSION

Embedding biomedical treatment of cancer within a dementia-friendly psychosocial system may enable safe cancer treatment for a greater number of people with dementia or milder cognitive impairment.

Navigating cancer treatment and care when living with comorbid dementia: an ethnographic study

Objectives

The risks of developing cancer and dementia increase as we age; however, this comorbidity remains relatively under-researched. This study reports on the challenges that people affected by comorbid cancer and dementia face when navigating engagement with cancer treatment within secondary care.

Materials and methods

An ethnographic study recruiting 17 people with cancer and dementia, 22 relatives and 19 oncology staff in two UK National Health Service Trusts. Observations (46 h) and informal conversations were conducted during oncology appointments involving people with dementia. Semi-structured interviews (n = 37) with people living with cancer and dementia, their relatives and staff working in various roles across oncology services were also carried out. Data were analysed using ethnographically informed thematic analysis.

Results

People with cancer and dementia experienced challenges across three areas of navigating cancer treatment and care: navigating through multiple services, appointments and layers of often complex information; repeatedly navigating transport to and from hospital; and navigating non-dementia-friendly hospital outpatient environments alongside the cognitive problems associated with dementia.

Conclusions

Dementia impacts patients’ abilities to navigate the many practical aspects of attending hospital for cancer treatment and care. This study indicates the importance of addressing ways to improve the experience of travelling to and from the hospital, alongside extending the ongoing efforts to develop ‘dementia-friendly’ hospital in-patient areas and practices, to outpatient departments. Such steps will serve to improve hospital-based cancer treatment and care and more broadly outpatient appointment experiences for people with dementia and their families.

An Overview of Treating People with Comorbid Dementia: Implications for Cancer Care

With increasing prevalence of both cancer and dementia in the UK, due to an ageing population, oncology healthcare professionals will experience higher numbers of people with both conditions. As dementia is highly heterogeneous and symptoms vary from individual to individual, it presents specific challenges for healthcare professionals, people with dementia and caregivers alike. This overview will describe current theories that explain the association between cancer and dementia, report prevalence rates and highlight the evidence on the impact of having a diagnosis of dementia on outcomes along the cancer pathway from cancer symptom detection to cancer treatment outcomes. It suggests that although prevalence rates of cancer and dementia are typically lower than other comorbidities, people with cancer and dementia have poorer cancer-related outcomes. This includes later stage cancer diagnoses, fewer cancer treatment options and an increased risk of death compared with people who have cancer alone or other comorbid conditions. Considerations for cancer treatment decision making and management are proposed to improve patient experience for this group.

Decision-making in cancer care for people living with dementia

OBJECTIVE

Increasing numbers of people are expected to live with comorbid cancer and dementia. Cancer treatment decision-making for these individuals is complex, particularly for those lacking capacity, requiring support across the cancer care pathway. There is little research to inform practice in this area. This ethnographic study reports on the cancer decision-making experiences of people with cancer and dementia, their families, and healthcare staff.

METHODS

Participant observations, informal conversations, semi-structured interviews, and medical note review, in two NHS trusts. Seventeen people with dementia and cancer, 22 relatives and 19 staff members participated.

RESULTS

Decision-making raised complex ethical dilemmas and challenges and raised concerns for families and staff around whether correct decisions had been made. Whose decision it was and to what extent a person with dementia and cancer was able to make decisions was complex, requiring careful and ongoing consultation and close involvement of relatives. The potential impact dementia might have on treatment understanding and toleration required additional consideration by clinicians when evaluating treatment options.

CONCLUSIONS

Cancer treatment decision-making for people with dementia is challenging, should be an ongoing process and has emotional impacts for the individual, relatives, and staff. Longer, flexible, and additional appointments may be required to support decision-making by people with cancer and dementia. Evidence-based decision-making guidance on how dementia impacts cancer prognosis, treatment adherence and efficacy is required.

Enabling people with dementia to access and receive cancer treatment and care: The crucial role of supportive networks

OBJECTIVES

Despite cancer and dementia being conditions in which prevalence increases with age, there remains limited research on the cancer treatment and care needs of this population. Our study aimed to address this gap and this paper reports on the role of supportive networks in enabling people with dementia to access cancer treatment and care.

MATERIALS AND METHODS

An ethnographic study involving seventeen people with cancer and dementia, 22 relatives and nineteen oncology staff. It comprised observations (46 h) of and informal conversations during oncology appointments attended by people with dementia and their relatives and semi-structured interviews (n = 37) with people living with cancer and dementia, their relatives and staff working in various roles across oncology services. Data were analysed using thematic analysis.

RESULTS

Patients and oncology staff relied on and expected relatives to provide practical and emotional support around cancer treatment and care. Families varied in their ability to provide required support due to extent of the family network, practical issues, knowledge of the patient and their wishes, family conflict and the patient's willingness to accept help. Where no family network was available, support provision was complex and this could compromise access to cancer treatment.

CONCLUSIONS

People with comorbid cancer and dementia rely heavily on a supportive family network to access treatment and care. Oncology services need to assess the supportive networks available to individual patients in developing cancer treatment plans. Urgent consideration needs to be given to how those with no family networks can be appropriately supported.

Embracing the complexity: Older adults with cancer-related cognitive decline-A Young International Society of Geriatric Oncology position paper

Cancer-related cognitive decline (CRCD) may have particularly significant consequences for older adults, impacting their functional and physical abilities, level of independence, ability to make decisions, treatment adherence, overall quality of life, and ultimately survival. In honor of Dr. Hurria's work we explore and examine multiple types of screening, assessment and non-pharmacologic treatments for CRCD. We then suggest future research and clinical practice questions to holistically appreciate the complexity of older adults with cancer's experiences and fully integrate the team-based approach to best serve this population.

S2k guidelines for Merkel cell carcinoma (MCC, neuroendocrine carcinoma of the skin) - update 2018

Merkel cell carcinoma (MCC, ICD-O M8247 / 3) is a rare malignant primary skin tumor with epithelial and neuroendocrine differentiation. The neoplastic cells share many morphological, immunohistochemical and ultrastructural characteristics with Merkel cells of the skin. The diagnosis of MCC is rarely made on clinical grounds. Histological and immunohistochemical studies are usually required to confirm the clinical suspicion. Given the frequent occurrence of occult lymph node metastasis, sentinel lymph node biopsy should be performed once distant metastasis has been ruled out by cross-sectional imaging. Primary tumors without evidence of organ metastases are treated with complete surgical excision with appropriate surgical margins. Radiation therapy should be considered at all stages of the disease. For advanced MCC that is no longer amenable to curative treatment by surgery or radiation therapy, there is currently no established systemic therapy for which an improvement in recurrence-free survival or overall survival has been demonstrated in a prospective randomized trial. However, immunotherapy using PD-1/PD-L1 blockade seems to be superior to chemotherapy. Various factors warrant that further diagnostic and therapeutic interventions be determined by an interdisciplinary tumor board. These factors include the tumor's aggressiveness, the frequent indication for sentinel lymph node biopsy along with the frequent occurrence in the head and neck region, the potential indication for adjuvant radiation therapy as well as the complexity of the required diagnostic workup.

How are caregivers involved in treatment decision making for older people with dementia and a new diagnosis of cancer?

OBJECTIVE

To explore how caregivers are involved in making treatment decisions for older people living with dementia and a new diagnosis of cancer.

METHOD

A systematic review of PubMed, CINAHL, PsycINFO, Web of Science, and Scopus databases was conducted. Studies recruiting formal or informal caregivers for older people with dementia and a diagnosis of cancer were considered for inclusion.

RESULTS

Of 1761 articles screened, 36 full texts were assessed for eligibility, and six were included in the review. This review has identified that health care professionals (HCPs) are often unaware of the coexistence or severity of dementia in cancer patients, and therefore fail to properly address care needs as a result. While caregivers are relied on to help make decisions, they have unmet information needs and feel excluded from decision-making.

CONCLUSION

Treatment decision making in the context of older adults with dementia and a new diagnosis of cancer needs further research. This will help HCPs to understand their needs and improve the experience of decision making for both caregivers and the people that they care for.

Living with and beyond cancer with comorbid illness: a qualitative systematic review and evidence synthesis

Purpose

To identify the qualitative evidence on the experience of cancer and comorbid illness from the perspective of patients, carers and health care professionals to identify psycho-social support needs, experience of health care, and to highlight areas where more research is needed.

Methods

A qualitative systematic review following PRISMA guidance. Relevant research databases were searched using an exhaustive list of search terms. Two reviewers independently screened titles and abstracts and discussed variations. Included articles were subject to quality appraisal before data extraction of article characteristics and findings. Thomas and Harden’s thematic synthesis of extracted findings was undertaken.

Results

Thirty-one articles were included in the review, covering a range of cancer types and comorbid conditions; with varying time since cancer diagnosis and apparent severity of disease for both cancer and other conditions. The majority of studies were published after 2010 and in high income countries. Few studies focused exclusively on the experience of living with comorbid conditions alongside cancer; such that evidence was limited. Key themes identified included the interaction between cancer and comorbid conditions, symptom experience, illness identities and ageing, self-management and the role of primary and secondary care.

Conclusions

In addition to a better understanding of the complex experience of cancer and comorbidity, the review will combine with research prioritisation work with consumers to inform an interview study with the defined patient group.

Implications for Cancer Survivors

Expanding this evidence base will help to illuminate developing models of cancer patient-centred follow-up care for the large proportion of patients with comorbid conditions.

Bridging the divide: the adjustment and decision-making experiences of people with dementia living with a recent diagnosis of cancer and its impact on family carers

The risk of living with dementia and, separately, cancer, increases exponentially with age. However, to date, there is a paucity of research investigating the experiences of people living with both these conditions. This study used semi-structured interviews to explore the decision-making and treatment options for people who live with both dementia and cancer. In total, ten people living with both dementia and cancer (aged 39–93 years) and nine family carers were interviewed. Braun and Clarke's approach to thematic analysis was used together with framework matrices to organise the data. In this article four sequential and descriptive themes are presented. ‘Reaching a diagnosis of cancer’ describes the vital role that family carers play in encouraging the person with dementia to seek an explanation for their presenting (undiagnosed cancer) symptoms to their general practitioner. ‘Adjusting to the cancer diagnosis when living with dementia’ outlines a variety of emotional and practical responses to receiving news of the diagnosis. ‘Weighing up the cancer treatment options’ highlights the different decisions and circumstances that family carers and people living with both dementia and cancer are faced with post-diagnosis. ‘Undergoing cancer treatment’ shares the finding that cancer treatment decision-making was not straightforward and that people living with both dementia and cancer would often forget about their cancer and what procedures they had been through.

Cancer-related information needs and treatment decision-making experiences of people with dementia in England: a multiple perspective qualitative study

OBJECTIVES

Little is known about the cancer experience and support needs of people with dementia. In particular, no evidence currently exists to demonstrate the likely complex decision-making processes for this patient group and the oncology healthcare professionals (HCP) involved in their care. The aim of this study was to explore the cancer-related information needs and decision-making experiences of patients with cancer and comorbid dementia, their informal caregivers and oncology HCPs.

DESIGN

Cross-sectional qualitative study. Semistructured interviews were conducted face to face with participants. Interviews were audio recorded and transcribed prior to thematic analysis.

SETTING

Patients with a diagnosis of cancer and dementia, their informal caregivers and oncology HCPs involved in their care, all recruited from a regional treatment cancer centre.

PARTICIPANTS

Purposeful sample of 10 patients with a diagnosis of cancer-dementia, informal caregivers (n=9) and oncology HCPs (n=12).

RESULTS

Four themes were identified: (1) leading to the initial consultation-HCPs require more detailed information on the functional impact of dementia and how it may influence cancer treatment options prior to meeting the patient; (2) communicating clinically relevant information-informal caregivers are relied on to provide patient information, advocate for the patient and support decision-making; (3) adjustments to cancer care-patients with dementia get through treatment with the help of their family and (4) following completion of cancer treatment-there are continuing information needs. Oncology HCPs discussed their need to consult specialists in dementia care to support treatment decision-making.

CONCLUSIONS

Although patients with cancer-dementia are involved in their treatment decision-making, informal caregivers are generally crucial in supporting this process. Individual patient needs and circumstances related to their cancer must be considered in the context of dementia prognosis highlighting complexities of decision-making in this population. Oncology teams should strive to involve healthcare staff with dementia expertise as early as possible in the cancer pathway.

Carer Experience Supporting Someone With Dementia and Cancer: A Narrative Approach

In this article, we examine the challenges of informal carers supporting someone with dementia and cancer within the United Kingdom. Interviews were conducted with seven informal carers using a narrative approach to examine the construction of their experiences. Our findings demonstrate how informal carers navigate a path through complex cancer treatments and support their relative. A cancer diagnosis often requires multiple treatment visits to an oncology center, and this can be challenging for carers. They find that they need to coordinate and manage both health professionals and their relative in terms of getting access to appropriate services and support. This process can be particularly challenging in the presence of a cognitive impairment that often demands effective communication with different agencies. Carers frequently experienced multiple challenges including dealing with the stigma that is characteristic of the dementia experience and the added complexity of negotiating this within a cancer care context.
