Abstract
Objective This study identified the potential subgroups of fear of cancer recurrence (FCR) in family caregivers (FCs) of patients with hematologic malignancies receiving chemotherapy, as well as exploring factors associated with subgroups. Methods This was a cross-sectional study involving 206 pairs of participating patients with hematologic malignancies receiving chemotherapy and their FCs. Using Mplus 8.3 to perform the latent profile analysis of FCs' FCR, the FCs' burden, quality of life, psychological resilience, and anxiety as well as their demographic characteristics were compared between the subgroups, with a logistic regression analysis being applied to examine the factors associated with the FCR subgroups. Results A total of 206 FCs were classified into two subgroups: "a low level of FCR" (Class 1, 65.4%) and "a high level of FCR" (Class 2, 34.6%). Quality of life, anxiety, and frequency of chemotherapy were significantly associated with the two subgroups. Conclusions FCs of patients with hematologic malignancy receiving chemotherapy had two FCR subgroups, "a low level of FCR" and "a high level of FCR", in association with quality of life, anxiety, and frequency of chemotherapy. These findings provide the theoretical foundations for screening the FCR factor of FCs and conducting interventions for them.

Abstract
PURPOSE To investigate the level of fear of cancer recurrence (FCR) in spouses of patients with lymphoma and its relationship with patients' FCR, as well as the correlations between FCR, sense of spousal support (SSS), anxiety, and depression in the couples. METHODS A cross-sectional study of 233 couples where one partner had lymphoma was conducted from May 2021 to February 2022. Participants provided demographic information and completed the Spouse Support Inventory and Hospital Anxiety and Depression Scale. The Fear of Progression Questionnaire (for patients) and Fear of Progression Questionnaire for Partners (for spouses) were used to measure FCR. Descriptive analyses, t-tests, variance analysis, Spearman's correlation analysis, and multiple linear regression analysis was performed. RESULTS The prevalence of FCR, anxiety, and depression in patients was 37.7%, 68.7%, and 83.3%, respectively. The prevalence of FCR, anxiety, and depression in spouses was 56.2%, 78.1%, and 81.1%, respectively. Spouses' FCR scores were higher than those of patients, whereas patients' SSS and anxiety scores were higher than those of their spouses. Multiple linear regression analysis showed that patients' anxiety and SSS, as well as spouses' FCR were significantly associated with patients' FCR. Variables significantly associated with higher FCR among spouses were anxiety, per capita monthly household income, and patients' FCR. CONCLUSIONS Patients with lymphoma and their spouses have a certain degree of FCR, anxiety, and depression. FCR levels in spouses are higher than in patients. IMPLICATIONS FOR CANCER SURVIVORS Psychological support interventions for couples may be effective in reducing FCR and facilitating family adaptation to cancer.

Demirbas M, Hahn-Pedersen JH, Jørgensen HL. Comparison Between Burden of Care Partners of Individuals with Alzheimer's Disease Versus Individuals with Other Chronic Diseases. Neurol Ther 2023; 12:1051-1068. [PMID: 37222859 PMCID: PMC10310688 DOI: 10.1007/s40120-023-00493-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 05/05/2023] [Indexed: 05/25/2023] Open
Abstract
BACKGROUND Caregiving in Alzheimer's disease (AD) is often provided by informal care partners, who spend more hours per week on average than care partners of individuals with conditions other than AD. However, the burden of care in partners of individuals with AD has not been systematically compared to that of other chronic diseases. OBJECTIVE The current study therefore aims to compare the care partner burden of AD to that of other chronic diseases through a systematic literature review. METHODS Data was collected from journal articles published in the last 10 years, using two unique search strings in PubMed and analysed using pre-defined patient-reported outcome measures (PROMs) including the EQ-5D-5L, GAD-7, GHQ-12, PHQ-9, WPAI and the ZBI. The data was grouped according to the included PROMs and the diseases studied. The number of participants in the studies reporting burden of caregiving in AD was adjusted to reflect the number of participants in studies reporting care partner burden in other chronic diseases. RESULTS All results in this study are reported as a mean value and standard deviation (SD). The ZBI measurement was the most frequently used PROM to collect care partner burden (15 studies) and showed a moderate burden (mean 36.80, SD 18.35) on care partners of individuals with AD, higher than most of the other included diseases except for those characterized by psychiatric symptoms (mean scores 55.92 and 59.11). Other PROMs such as PHQ-9 (six studies) and GHQ-12 (four studies) showed a greater burden on care partners of individuals with other chronic diseases such as heart failure, haematopoietic cell transplantations, cancer and depression compared to AD. Likewise, GAD-7 and EQ-5D-5L measurements showed a lesser burden on care partners of individuals with AD compared to care partners of individuals with anxiety, cancer, asthma and chronic obstructive pulmonary disease. The current study suggests that care partners of individuals with AD experience a moderate burden, but with some variations depending on the PROMs used. CONCLUSION The results of this study were mixed with some PROMs indicating a greater burden for care partners of individuals with AD versus other chronic diseases, and other PROMs showing a greater burden for care partners of individuals with other chronic diseases. Psychiatric disorders imposed a greater burden on care partners compared to AD, while somatic diseases in the musculoskeletal system resulted in a significantly smaller burden on care partners compared to AD.

Abstract
OBJECTIVE Fear of cancer recurrence (FCR) is reported by both cancer survivors and caregivers however less is known about caregiver FCR. This study aimed to (a) conduct a meta-analysis to compare survivor and caregiver FCR levels; (b) examine the relationship between caregiver FCR and depression, and anxiety; (c) evaluate psychometric properties of caregiver FCR measures. METHODS CINAHL, Embase, PsychINFO and PubMed were searched for quantitative research examining caregiver FCR. Eligibility criteria included caregivers caring for a survivor with any type of cancer, reporting on caregiver FCR and/or measurement, published in English-language, peer-review journals between 1997 and November 2022. The COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) taxonomy was used to evaluate content and psychometric properties. The review was pre-registered (PROSPERO ID: CRD42020201906). RESULTS Of 4297 records screened, 45 met criteria for inclusion. Meta-analysis revealed that caregivers reported FCR levels as high as FCR amongst survivors, with around 48% of caregivers reporting clinically significant FCR levels. There was a strong correlation between anxiety and depression and medium correlation with survivor FCR. Twelve different instruments were used to measure caregiver FCR. Assessments using the COSMIN taxonomy revealed few instruments had undergone appropriate development and psychometric testing. Only one instrument met 50% or more of the criteria, indicating substantial development or validation components were missing in most. CONCLUSIONS Results suggest FCR is as often a problem for caregivers as it is for survivors. As in survivors, caregiver FCR is associated with more severe depression and anxiety. Caregiver FCR measurement has predominately relied on survivor conceptualisations and unvalidated measures. More caregiver-specific research is urgently needed.

Abstract
OBJECTIVE Ovarian cancer (OC) can significantly change the way women feel about their body. However, personal accounts regarding these changes are lacking in the literature. Therefore, the aim of this study was to gain an understanding of the ways in which OC can affect relationships, sexuality, womanhood and body image. METHODS Ninety-eight Australian women aged 18 and over diagnosed with OC completed an online survey that invited narrative responses to open-ended questions about relationships, sexuality, body image and womanhood following OC treatment. Responses were analysed thematically while applying a sociocultural lens. RESULTS Three themes and two subthemes were identified: Failure and Loss of Femininity and Womanhood, Internalising Public Perception of Body and Illness and Altered Relationships which comprised two subthemes, Loss of the Sexual Self and Relationship Burden. These themes suggest women view themselves and their relationships in comparison with sociocultural understandings of body normalcy. Women often questioned their self-worth, their relationships and place within society due to changes in fertility, sexuality and bodily functioning. CONCLUSION These results highlight a need for health care professionals to open dialogue with women about sexuality and ensure information and support is given to reduce stigma and positively influence self-perception and increase body acceptance.

Abstract
Increasing evidence on men's involvement in informal, unpaid care has not transferred to the research literature around men's experiences. The aim was to explore the perspectives of men who are caring for a female partner with cancer over 1 year. Longitudinal narrative interviews (n = 22) were conducted with eight men in the UK from 2018 to 2019. Participants were aged from 32 to 76 years old, were all white British and in heterosexual relationships with women diagnosed with a range of cancer types. Interviews were transcribed and then analysed using a structural and performance approach to narrative analysis. We present, across four scenes, a process of change, transition and emotion management as the men were launched into a role that came with new responsibilities and expectations. Our study advances knowledge by highlighting the way that men perform and reflect on their negotiation with masculine discourses while supporting their partner, with implications for policy, research and practice.

Abstract
PURPOSE Cancer impacts caregivers as well as patients. Ambulatory oncology surgeries requiring a short hospital stay place additional responsibility on informal caregivers as they help patients navigate their post-operative recovery at home, and determine if symptoms are expected or emergent. Our objective was to explore the experience of informal caregivers during patients' ambulatory cancer surgery and then recovery at home with remote monitoring of symptoms via web-based patient-reported outcomes questionnaire ("Recovery Tracker"). METHODS Semi-structured interviews were conducted with caregivers from a larger sample participating in a randomized trial of the Recovery Tracker. Thematic analysis was applied to derive key themes and codes via NVivo qualitative analysis software (QSR International Inc.). Recruitment was conducted iteratively to ensure a heterogenous sample and thematic saturation. RESULTS Twenty-three semi-structured interviews were conducted. Four main themes emerged: (1) Predictability reduced stress among caregivers; (2) Unexpected events caused stress for caregivers; (3) The importance of a caregiver being present during the recovery process; and (4) Caregiver involvement in remote monitoring of symptoms was minimal. CONCLUSION Caregivers report not being overly burdened by the ambulatory surgery process, but they are very sensitive to any deviations from what they expected to happen. Further research and clinical practice on caregivers in the ambulatory setting should focus on how to set expectations and avoid unexpected events.

Abstract
Ovarian cancer is the fourth-most-common cause of death among all malignant cancers in women in Poland. This study aimed to compare the functioning of the urinary system and quality of life in women in the 12-month period following the completion of surgery or adjuvant treatment for ovarian cancer, with patients who underwent a hysterectomy for non-oncological reasons (control group). The study group consisted of 50 patients diagnosed with stage I−III ovarian cancer. Among 38 patients with type II ovarian cancer (group A), surgery followed by first-line chemotherapy was performed. Within this group of patients, 20 had stage I ovarian cancer, while 18 had stage II ovarian cancer. The study was performed at least 6 months after the final chemotherapy cycle, with no clinical, marker or radiological recurrence determined. On the other hand, in 12 patients with stage I type I ovarian cancer, oncological treatment consisted of only surgery, without the need for adjuvant chemotherapy, due to the low stage of the lesions (group B). In turn, the control group consisted of 50 women who underwent uterine removal for non-oncological reasons (group C). The assessment of quality of life was conducted using the questionnaires: Satisfaction with Life Scale (SWLS); Incontinence Impact Questionnaire, short form (IIQ-7); Urogenital Distress Inventory (UDI-6); and the Sexual Satisfaction Scale for 3, 6, 9, and 12 months after the conclusion of oncological treatment. During the follow-up, a significant reduction in the quality of everyday life and sexual life was noted among patients with ovarian cancer, more pronounced in group B, compared to the control group (p < 0.05). The risk of urinary incontinence is independent of the treatment regimen chosen for ovarian cancer. It is necessary to consider comprehensive psychological care and sexual therapy in patients with ovarian cancer and their families.
