Healthcare use and fear of recurrence in adult cancer survivors at 2.5years after a cancer diagnosis: a nationwide register study in Denmark.

To investigate the association between fear of cancer recurrence (FCR) and healthcare use in general practice among cancer survivors. We linked nationwide register data to survey data on FCR in cancer survivors at 2.5years after a cancer diagnosis. Multiple regression models were used to analyse the association between high FCR level and quartiles of healthcare use at 18-30months before the cancer diagnosis (habitual healthcare use) and between high FCR level and healthcare use at 18-30months after the cancer diagnosis (survivorship healthcare use). We included 1538 cancer survivors in the study. High habitual healthcare use was associated with a high level of FCR (odds ratio = 2.07 (95% confidence interval (CI): 1.36-3.15)) for the 4th quartile of healthcare use compared to the 1st quartile. A high FCR score was also associated with higher healthcare use during cancer survivorship (incidence rate ratio (IRR) = 1.26 (95% CI: 1.14-1.40)). This association remained statistically significant when adjusting for habitual healthcare use (IRR = 1.20 (95% CI: 1.09-1.33)). High healthcare use before the cancer diagnosis was associated with high FCR during survivorship. This indicates that FCR is partly explained by a general (pre-diagnostic) health concern. High FCR predicted high healthcare use during cancer survivorship, even when adjusting for habitual healthcare use. Our results suggest that FCR in cancer survivors is triggered by a general high level of health concern, and the cancer diagnosis may further exacerbate this concern.

Exploring Fear of Cancer Recurrence (FCR) in cancer survivors from a medical social work perspective: A qualitative study of medical social workers in South Korea

Background Fear of Cancer Recurrence (FCR) in cancer survivors has been insufficiently addressed despite its imperativeness in cancer journey. Although several studies have investigated healthcare professionals’ experience with FCR in cancer survivors, a medical social work perspective has rarely been reflected. This study aimed to explore Korean medical social workers’ experience with intervening FCR in cancer survivors. Methods Snowball sampling recruited 12 experienced medical social workers intervening with cancer survivors at tertiary or university cancer hospitals in South Korea. Individual and focus-group interviews (FGI) were conducted with the medical social workers. The interviews were recorded, transcribed, and analyzed by using an inductive qualitative content analysis. Results Content analysis of the interviews extracted the following major themes regarding FCR in cancer survivors. First, when and how FCR among cancer survivors emerged at the early stage of medical social work interventions was identified. Second, how medical social workers dealt with FCR in cancer survivors was illustrated. Third, the responses of cancer survivors to medical social work interventions for FCR were assessed. Finally, the internal and external issues underlying the medical social work interventions for FCR among cancer survivors were revealed and discussed. Conclusion Based on the results, this study suggested the implications on dealing with FCR in cancer survivors in the realm of medial social work profession. Furthermore, it expanded the discussion about FCR in cancer survivors from cancer hospitals to community.

Social Support and Fear of Cancer Recurrence Among Chinese Breast Cancer Survivors: The Mediation Role of Illness Uncertainty.

ObjectiveTo examine the relations between social support, illness uncertainty (IU), and fear of cancer recurrence (FCR).MethodsUsing data from a convenience sample of 231 breast cancer survivors in China to perform structural equation modeling with bootstrapping estimation. Participants were recruited from a general hospital in Shenyang, China. Participants completed the Perceived Social Support Scale, Mishel Uncertainty in Illness Scale, and Fear of Cancer Recurrence Inventory- Shorter Form.ResultsThe majority of breast cancer survivors have FCR (67.5%). FCR was significantly negatively associated with social support, and was significantly positively associated with IU (both P < 0.01). Moreover, IU was found to mediate the relationship between social support and FCR (standardized indirect effect = –0.18; bias-corrected 95% confidence interval: –0.255, –0.123).ConclusionThe findings support the final model. Good social support can directly mitigate FCR, while illness uncertainty can play a mediation role between social support and FCR. Further studies should be conducted to explore effective interventions for social support and IU to ultimately mitigate FCR in cancer survivors.

On top of that all, now Covid-19, too. A scoping review of specificities and correlates of fear of cancer recurrence in breast cancer patients during COVID-19.

Fear of cancer recurrence (FCR) is a normal response in cancer survivors and one of the most prevalent reactions reported by up to 87% of them. However, elevated levels of FCR impair well-being, quality of life and professional functioning, and lead to anxiety, depression or PTSD. COVID-19 pandemic can exacerbate FCR symptoms, given the restricting access to follow-up investigations and treatment, the isolation restrictions imposed and the possibility of the medical system becoming overworked. This scoping review's objective was to synthesize the literature investigating the factors associated with higher levels of FCR in cancer survivors during the COVID-19 pandemic. The focus was on FCR in breast cancer patients, including most of the studies (5 out of 9) on this topic. However, given the novelty of the subject, the increased interest in it, and the fact that there are few studies in this field, the review included 4 other studies with mixed samples of patients with breast cancer and other oncological pathologies. Following rigorous methodological criteria, 9 studies with quantitative or mixed methodology were included (N = 4831 patients). The results indicate that high levels of FCR are associated with distress and concerns regarding the pandemic impact, with most common concerns of patients being changes in treatment plan (delays and interruptions), dysfunctional communication with medical staff or difficult access to food or medicine. The most common correlates of FCR during the pandemic are marital status, childlessness, low financial status, level of education, type of cancer diagnosis, generalized anxiety and depression.

Interpretation Bias in Breast Cancer Survivors Experiencing Fear of Cancer Recurrence.

Introduction: Fear of cancer recurrence (FCR) is a prevalent and persistent challenge that many cancer survivors endure. While the role of interpretation bias, a tendency to perceive ambiguous situations as threatening, has been established in the onset and maintenance of FCR, few studies have examined cancer-related interpretation bias specifically. Grounded in the cognitive formulation of FCR, the current study aimed to fill this gap by investigating the relationship between cancer-related interpretation bias, FCR, and somatic symptoms, and examining whether bias mediates the relationship between somatic symptoms and FCR.Materials and Methods: This study used baseline data from a randomized controlled trial of a cognitive bias modification intervention. Breast cancer survivors (n = 110) provided demographic and medical background information as well as self-report measures of FCR and severity of somatic symptoms. A computer-based assessment of interpretation bias was used to measure cancer-related interpretation bias on several bias indices: percentage of cancer-related threat endorsement, and percentage of benign endorsement; mean reaction time (RT) for threat, and mean RT for benign endorsement.Results: Higher threat endorsement was linked to higher Overall Fear and emerged as a mediator of the relationship between overall somatic symptoms and Overall Fear. We also found that older age was related to longer benign endorsement RT.Conclusion: This study contributes understanding of factors related to cancer-related interpretation bias and provides evidence that bias may influence the relationship between somatic symptoms and FCR in cancer survivors.

Factors Correlated With Fear of Cancer Recurrence in Cancer Survivors: A Meta-analysis.

Fear of cancer recurrence (FCR) is one of the most common and aversive psychological phenomena among cancer survivors. Understanding the independent and potentially modifiable risk factors that contribute toward FCR seen in cancer survivors would inform future interventional trials aimed at reducing this risk. The aim of this study was to provide an evidence synthesis of factors correlated with FCR to inform the development of preventive interventions. A literature search was performed of the PsycINFO, EMBASE, and MEDLINE (PubMed) databases. Reports published from inception to 2020 focusing on the correlates of FCR with physical, psychological, and social factors were identified. Authors assessed the studies' risk of bias in accordance with the Standard Quality Assessment Criteria for Quantitative Studies (QualSyst criteria) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. After extracting data and assessing the quality of the included studies, meta-analysis was conducted using RevMan 5.3 software. Thirty-four articles were included in this study with a total sample of more than 13 000 cancer patients. Fear of cancer recurrence was positively correlated with anxiety, depression, avoidance, chemotherapy, distress, intrusive thoughts, fatigue, rumination, and neuroticism. It was negatively correlated with optimism, age, social support, quality of life, time since diagnosis, well-being, and self-efficacy. We identified 16 factors that are correlated with FCR, 9 positively correlated with FCR and 7 negatively correlated with FCR. The findings of this study provide direction for the development of precise interventions for FCR in cancer survivors and lay the foundation for the further construction of an FCR-related nursing theoretical framework.

The Association Between Fear of Cancer Recurrence and the Gut Microbiota in Breast Cancer Survivors (P05-030-19)

ObjectivesDysfunctional processing of fear memory may be involved in the pathophysiology of fear of cancer recurrence (FCR), which is cited as the major unmet psychological need of cancer survivors. Emerging evidence has shown that the microbiota-gut-brain (MGB) axis affects psychiatric disorders, including depressive and anxiety disorders, which are associated with fear memory (PMID: 29628046). We therefore hypothesized that the gut microbiota is associated with FCR in cancer survivors (PMID: 29628046). MethodsThis cross-sectional study enrolled women diagnosed with invasive breast cancer who were not currently undergoing chemotherapy. Fecal samples were obtained to assess the gut microbiota. FCR grade was assessed using the Concerns About Recurrence Scale (CARS). ResultsMean age of the participants (n = 126) was 58 years; 47% had stage I disease. Multiple regression analysis with adjustment for possible confounders showed that the relative abundance of the Bacteroides genus (beta = 0.180, P = 0.03) was significantly and directly associated with FCR. In the 57 participants with a history of chemotherapy, higher FCR was associated with lower microbial diversity (P = 0.04), lower relative abundance of Firmicutes (P = 0.03) and higher relative abundance of Bacteroidetes (P = 0.04) at the phylum level, and higher relative abundance of Bacteroides (P < 0.01) and lower relative abundance of Lachnospiraceae.g (P = 0.03) and Ruminococcus (P = 0.02) at the genus level. ConclusionsOur findings provide the first evidence of an association between the gut microbiota and FCR and suggest that chemotherapy-induced changes in gut microbiota can influence FCR. Further studies should examine the effects of the gut microbiota on FCR using a prospective design. Funding SourcesThis study was supported in-part by a donation from Morinaga Milk Industry Co.

Impact of chemotherapy on the association between fear of cancer recurrence and the gut microbiota in breast cancer survivors

BackgroundDysfunctional processing of fear memory may be involved in the pathophysiology of fear of cancer recurrence (FCR), which is cited as the major unmet psychological need of cancer survivors. Emerging evidence has shown that the microbiota-gut-brain (MGB) axis affects depressive and anxiety disorders, and chemotherapy-associated psychological distress. We therefore hypothesized that the gut microbiota is associated with FCR in cancer survivors. MethodsThis cross-sectional study enrolled women diagnosed with invasive breast cancer who were not currently undergoing chemotherapy. Fecal samples were obtained to assess the gut microbiota. FCR grade was assessed using the Concerns About Recurrence Scale (CARS). ResultsMean age of the participants (n = 126) was 58 years; 47% had stage I disease. Multiple regression analysis with adjustment for possible confounders showed that the relative abundance of the Bacteroides genus (beta = 0.180, p = 0.03) was significantly and directly associated with FCR.

ConclusionOur findings provide the first evidence of an association between the gut microbiota and FCR and suggest that chemotherapy-induced changes in gut microbiota can influence FCR. Further studies should examine the effects of the gut microbiota on FCR using a prospective design.

Fear of cancer recurrence among breast cancer survivors could be controlled by prudent dietary modification with polyunsaturated fatty acids

BackgroundThe pathophysiology of fear of cancer recurrence (FCR), the leading unmet psychological need of cancer survivors, may involve the dysfunctional processing of fear memory. n-3 polyunsaturated fatty acids (PUFAs) have beneficial effects on psychiatric disorders, including depressive disorder and anxiety disorders, and are involved in fear memory processing. We hypothesized that n-3 PUFA composition is associated with FCR in cancer survivors. MethodsWe conducted a cross-sectional study to examine the relationship between n-3 PUFAs and FCR among breast cancer survivors. Adults who had been diagnosed with invasive breast cancer and were not undergoing chemotherapy were asked to participate. Blood PUFA composition was evaluated by using capillary blood. We directly administered the Concerns About Recurrence Scale (CARS) to assess the grade of FCR. ResultsAmong 126 participants used for the analysis, the mean age (SD) was 58 (11) years and 47% had stage I cancer. Multiple regression analysis controlling for possible confounders, depressive symptoms, and post-traumatic stress disorder (PTSD) symptoms revealed that the alpha-linolenic acid (ALA) level was significantly inversely associated with the average score on the CARS overall fear index (beta = −0.165, p = 0.04). No significant associations were found for other PUFAs. LimitationsOur findings were obtained from a cross-sectional study in a single institute. ConclusionThese findings provide the first evidence of a beneficial effect of ALA on FCR and indicate the need for prospective study of this association. FCR among breast cancer survivors might be controllable by prudent selection of ALA-containing cooking oil.

Long-term results of a phase II randomized controlled trial (RCT) of a psychological intervention (Conquer Fear) to reduce clinical levels of fear of cancer recurrence in breast, colorectal, and melanoma cancer survivors.

LBA10000 Background: Up to 70% of cancer survivors report clinically significant fear of cancer recurrence (FCR). This parallel RCT evaluated the impact of a psychological intervention, Conquer Fear (CF), on FCR in cancer survivors. Methods: Participants were disease-free stage I-III breast, colorectal or melanoma cancer survivors, 2 months to 5 years post-treatment, who scored above the clinical cut-off (≥13) on the FCR Inventory (FCRI) severity subscale. CF included 5 sessions incorporating attention training, detached mindfulness, challenging unhelpful metacognitions, values clarification and psycho-education. Participants were randomised to the intervention ( n= 121) or a relaxation training (RT) control arm ( n= 101) (target n= 260). The primary end-point was reduction in FCR (FCRI total) immediately after intervention completion. Follow-up assessments occurred immediately, 3- and 6-months post-treatment. Data analysis was by intention to treat. The differences in change in FCR from baseline between CF and RT and secondary outcomes were tested using independent t-tests. A difference of 14.5 points in FCR was considered clinically significant. Long-term changes in FCR and secondary outcomes were evaluated using linear regression models fitted with generalized estimating equations (GEE), adjusted for baseline FCR. Results: Reduction in FCR between baseline and immediately post-treatment was significantly more in CF participants compared to RT. (Difference in change (95% CI): -10.5 (-16.1, -4.9); p &lt; 0.001). Greater FCR reductions were also observed amongst CF participants at 3 months (-7.6 (-13.9, -1.4), p = 0.02) and 6 months (-7.8 (-14.2, -1.4), p = 0.02) compared with RT. The pattern of change in outcomes over time was consistent between treatment groups as no significant linear trends in treatment effects over time were observed. Conclusions: Conquer Fear is a theoretically-grounded intervention to reduce FCR and its associated psychological morbidity which leads to significantly greater reductions in FCR in the first 6 months following treatment than relaxation training.

Efficacy of Blended Cognitive Behavior Therapy for High Fear of Recurrence in Breast, Prostate, and Colorectal Cancer Survivors: The SWORD Study, a Randomized Controlled Trial.

Purpose Fear of cancer recurrence (FCR) is a common problem experienced by cancer survivors. Approximately one third of survivors report high FCR. This study aimed to evaluate whether blended cognitive behavior therapy (bCBT) can reduce the severity of FCR in cancer survivors curatively treated for breast, prostate, or colorectal cancer. Patients and Methods This randomized controlled trial included 88 cancer survivors with high FCR (Cancer Worry Scale score ≥ 14) from 6 months to 5 years after cancer treatment. Participants were randomly allocated (ratio 1:1, stratified by cancer type) to receive bCBT, including five face-to face and three online sessions (n = 45) or care as usual (CAU; n = 43). Participants completed questionnaires at baseline (T0) and 3 months later (T1). The intervention group completed bCBT between T0 and T1. The primary outcome was FCR severity assessed with the Cancer Worry Scale. Secondary outcomes included other distress-related measures. Statistical (one-way between-group analyses of covariance) and clinical effects (clinically significant improvement) were analyzed by intention to treat. Results Participants who received bCBT reported significantly less FCR than those who received CAU (mean difference, -3.48; 95% CI, -4.69 to -2.28; P < .001) with a moderate-to-large effect size ( d = 0.76). Clinically significant improvement in FCR was significantly higher in the bCBT group than in the CAU group (13 [29%] of 45 compared with 0 [0%] of 43; P < .001); self-rated improvement was also higher in the bCBT group (30 [71%] of 42 compared with 12 [32%] of 38 in the CAU group; P < .001). Conclusion bCBT has a statistically and clinically significant effect on the severity of FCR in cancer survivors and is a promising new treatment approach.

Fear of cancer recurrence: a theoretical review and novel cognitive processing formulation.

Fear of cancer recurrence (FCR) is prevalent among survivors. However, a comprehensive and universally accepted theoretical framework of FCR to guide intervention is lacking. This paper reviews theoretical frameworks previously used to explain FCR and describes the formulation of a novel theoretical framework for FCR. A systematic review of the literature was undertaken to identify conceptual frameworks or theories applied to FCR. MEDLINE, PubMED, CINAHL, AMED, PsycINFO and Web of Science were searched. Identified conceptual frameworks were reviewed for strength of evidence supporting their validity. Of 558 papers initially identified, 16 made reference to six different conceptual frameworks relating to FCR. The most comprehensive and evidence-based theoretical approach is the Common Sense Model (CSM). Other approaches have limited evidence supporting their application to FCR. Two theoretical approaches developed in the context of emotional disorders that appear to be highly relevant to FCR: the Self-Regulatory Executive Function (S-REF) model and Relational Frame Theory were combined with the CSM to produce a novel cognitive processing account of FCR. Few conceptual frameworks have been used consistently to guide FCR research, and not all frameworks are empirically well supported, suggesting that further discussion regarding the conceptualisation of FCR is needed. The novel theoretical framework for FCR presented highlights the multidimensional nature of FCR and the importance of cognitive processing and metacognitions in the development and maintenance of FCR. The novel theoretical formulation of FCR outlined here provides a much-needed comprehensive framework to further investigate and address FCR in cancer survivors.

Fear of cancer recurrence in young early‐stage breast cancer survivors: the role of metacognitive style and disease‐related factors

Fear of cancer recurrence (FCR) is a common challenge of cancer survivorship, particularly in younger survivors. Maladaptive metacognitions have been shown to be important to the development of a range of emotional disorders but have not previously been explored in the context of FCR. This study aimed to explore the relationship between FCR and a maladaptive metacognitions. This cross-sectional study included young women diagnosed with early-stage breast cancer at least 1 year prior to study entry. Participants completed a web-based questionnaire, which included the Fear of Cancer Recurrence Inventory (FCRI) and the brief Metacognitions Questionnaire-30 (MCQ-30). Linear regression was used to calculate unadjusted and adjusted slope estimates of the association of FCR with six metacognition variables, the total score of the MCQ-30 and the five subscales. Two-hundred and eighteen women with a mean age of 39 years at diagnosis participated. All measures of metacognitive style were moderately correlated with FCRI scores (r=0.31-0.49) and significantly associated with FCRI in both unadjusted and adjusted models. Overall metacognitive style explained 36% of the variance in FCR scores in combination with disease and demographic factors. Negative metacognitions (R(2) =0.32) and need for control over cognition (R(2)=0.26) were the MCQ-30 subscales most associated with higher FCR. Unhelpful metacognitions appear to play an important role in FCR in young women with early-stage breast cancer. Treatments that focus on changing unhelpful metacognitions may prove a useful approach for treating clinical FCR in cancer survivors in the future.
