RESUMO

Objective: The prevalence of dementia and cancer has increased in recent years. The presence of dementia complicates the care of terminal cancer patients and affects their family caregivers. However, palliative care research seldom focuses on the family caregivers of patients with terminal cancer and dementia. This study aimed to evaluate the degree and factors of caregiver burden in cancer patients with dementia who died in hospice palliative care units. Methods: A nationwide cross-sectional survey was conducted among bereaved family members of patients with cancer who died in palliative care units. An anonymous self-report questionnaire was sent to bereaved family members, and they were asked if they were aware of the diagnosis of dementia. The short version of the Caregiver Consequence Inventory was used to measure caregiver burden. Results: The analysis included 670 bereaved family members. Of these, 83 (12.4%) were bereaved family members of terminal cancer patients with dementia. The caregiver burden was statistically significantly higher (3.61 ± 1.58 vs 3.22 ± 1.47; p < 0.036) among family caregivers of terminal cancer patients with dementia. Longer anti-cancer treatment duration (odd ratio, 4.63), poor mental and physical health of family caregivers (odds ratio, 2.05 and 2.20, respectively), pain (odd ratio, 1.72), and dyspnea (odds ratio, 1.67) were contributing factors for caregiver burden. Conclusions: Family caregivers of terminal cancer patients with dementia require care that considers the characteristics of the two serious diseases. Considering the goal of anti-cancer treatment and symptom relief may be a useful strategy for reducing caregiver burden.

RESUMO

OBJECTIVE: The present study aims to describe fall-related self-efficacy as perceived by patients with chemotherapy-induced peripheral neuropathy (CIPN). The characteristics of patients associated with low perceived self-efficacy of preventing falls were investigated. METHODS: A cross-sectional study of four hospitals in Japan. In this study, 100 outpatients who were receiving chemotherapy for cancer and experiencing CIPN were recruited. Participants completed an anonymous, self-administered questionnaire. Self-efficacy was measured with the falling self-efficacy (FSE) scale, and the severity and impact of CIPN was assessed with the Comprehensive Assessment Scale for CIPN in Survivors of Cancer (CAS-CIPN). Data about the demographic information of the patients, cancer diagnosis and treatment, pain and fatigue symptoms, and history of previous falls were collected. Logistic regression analysis was used to assess relationships between variables. RESULTS: A total of 81 (81.0%) participants with CIPN completed the questionnaire. They reported experiencing fear of falling during their daily activities, which include the act of standing up, walking, and using the stairs. Small events, such as unstable postures and uncomfortable situations, affected their confidence of preventing falls. Logistic regression revealed that low FSE scores were significantly associated with female sex (P = 0.022), low body mass index (BMI; P = 0.026), and the CAS-CIPN score (P < 0.001). CONCLUSIONS: Female patients with CIPN and low BMI might have an increased need for enhanced fall-related self-efficacy. A comprehensive assessment of CIPN in patients at risk of low FSE scores is likely to be beneficial.

RESUMO

CONTEXT: Unfinished business often causes psychological issues after bereavement. Providing care for families of terminally ill patients with cancer to prevent unfinished business is important. OBJECTIVES: To clarify the prevalence and types of unfinished business in families of end-of-life patients with cancer admitted to palliative care units (PCUs), explore depression and grief associated with unfinished business, and explore the factors affecting unfinished business. METHODS: We conducted a cross-sectional, anonymous, self-report questionnaire survey with 967 bereaved families of patients with cancer admitted to PCUs. The questionnaire assessed the presence or the absence of unfinished business, content of unfinished business, depression, grief, process of preparedness, condition of the family and patient, and the degree of involvement of health care professionals. RESULTS: Questionnaires were sent to 967 families, and 73.0% responded. In total, 26.0% of families had some unfinished business, with improvement of the patient-family relationship being a common type of unfinished business. Families with unfinished business had significantly higher depression and grief scores after bereavement compared with those without. Factors that influenced the presence or the absence of unfinished business were preparedness for the patient's death (P = 0.001), discussion between the patient and family about the disease trajectory and way to spend daily life (P < 0.001), good patient-family relationship (P = 0.011), and family and health care professionals considering together the appropriate timing to accomplish the family's wishes (P = 0.021). CONCLUSION: Many families have unfinished business. Health care professionals should coordinate the appropriate timing for what the family wishes to do, with consideration of family dynamics, including the family's preparedness, communication pattern, and relationships.

RESUMO

Extracellular free amino acids contribute to the interaction between a tumor and its microenvironment through effects on cellular metabolism and malignant behavior. System xc(-) is composed of xCT and CD98hc subunits and functions as a plasma membrane antiporter for the uptake of extracellular cystine in exchange for intracellular glutamate. Here, we show that the EGFR interacts with xCT and thereby promotes its cell surface expression and function in human glioma cells. EGFR-expressing glioma cells manifested both enhanced antioxidant capacity as a result of increased cystine uptake, as well as increased glutamate, which promotes matrix invasion. Imaging mass spectrometry also revealed that brain tumors formed in mice by human glioma cells stably overexpressing EGFR contained higher levels of reduced glutathione compared with those formed by parental cells. Targeted inhibition of xCT suppressed the EGFR-dependent enhancement of antioxidant capacity in glioma cells, as well as tumor growth and invasiveness. Our findings establish a new functional role for EGFR in promoting the malignant potential of glioma cells through interaction with xCT at the cell surface. Cancer Res; 76(10); 2954-63. ©2016 AACR.
