Towards the validation of a new, blended theoretical model of fear of cancer recurrence

It is Time to Address Fear of Cancer Recurrence in Family Caregivers: Feasibility and Acceptability of a Randomized Pilot Study of the Family Caregiver Version of the Fear of Recurrence Therapy (FC-FORT)

OBJECTIVE

Fear of cancer recurrence (FCR) is common, persistent, and associated with lower quality of life, impaired functioning, and psychological distress in family caregivers (FC) of individuals with a cancer diagnosis. Interventions are needed to specifically target FCR in FC. This study aimed to pilot test the adapted Family Caregiver-Fear Of Recurrence Therapy (FC-FORT) to establish its feasibility, acceptability, and clinical significance.

METHODS

This pilot study used a mixed-method, parallel, two-group randomized control trial (FC-FORT vs. waitlist control group) design. Women FC were recruited through Canadian hospitals, community partners, and social media. FC in the intervention group completed 7 weekly sessions of virtual group therapy (FC-FORT) and an exit interview. All participants completed questionnaires at baseline, post-intervention, and 3-month follow-up. Feasibility (e.g., recruitment, allocation, fidelity), acceptability (e.g., dropout, completion, satisfaction) and clinical significance of secondary outcomes were evaluated. Descriptive statistics, mixed ANOVAs, and conventional content analyses were used.

RESULTS

Regarding feasibility, 22 FC were recruited, 18 were randomized and therapist fidelity was 87%. As to acceptability, 67% of participants completed≥ ${\ge} $ 5 sessions (33% dropout). Questionnaire completion rate was 92%. FC satisfaction was 80%. Analyses did not reveal any significant differences on the secondary outcomes between groups. Qualitative analyses revealed high importance, helpfulness, satisfaction, and group cohesion. Suggestions were made by FC for improvements.

CONCLUSIONS

This is one of the first interventions to address FCR in FC. While acceptability of FC-FORT was good, important feasibility issues need to be addressed before moving forward with a larger randomized control trial.

Investigation of the Relationship Between Intolerance of Uncertainty, Metacognitions, Maladaptive Coping, and Fear of Cancer Recurrence via Moderated Mediation Model

OBJECTIVE

In recent years, many studies have investigated the triggers, perpetuating factors, and outcomes of Fear of Cancer Recurrence (FCR), highlighting its complexity with multiple dimensions that encompass both antecedents and consequences. In this sense, the cognitive approach to FCR has explored variables such as metacognition, maladaptive coping strategies, and intolerance of uncertainty (IU). On the other hand, the findings of a restricted number of studies investigating the relationship between FCR and stated variables appear to be inconsistent. The objective of this study was thus to examine the relationship that existed among these variables in breast cancer survivors by moderated mediation model.

METHODS

In this cross-sectional study, 130 breast cancer survivors completed the Fear of Cancer Recurrence Inventory (FCRI), the Intolerance of Uncertainty Scale Short Form (IUS-12), Metacognitions Questionnaire-30 (MCQ-30), and Brief COPE Scale (BCS) Short Form. The mediated moderation analysis was conducted using Process Macro.

RESULTS

There was a significant positive correlation found between FCR and IU (r = 0.87, p < 0.001), and between FCR and negative metacognitions (r = 0.72, p < 0.001). A weak to moderate positive correlation was identified between IU and maladaptive coping strategies (r = 0.19, p < 0.05), and between negative metacognitions and maladaptive coping strategies (r = 0.31, p < 0.001). The relationship between FCR and maladaptive coping strategies was nonsignificant (r = 0.16, p > 0.05). As a result of hierarchical regression analysis, controlling for demographic and clinical variables, IU, positive metacognitions, and negative metacognitions significantly explained 45%, 2%, and 1% of the variance in FCR, respectively.

CONCLUSION

The results of the current study contribute to the literature in terms of supporting the views that cognitive models of worrying could be used to understand the FCR mechanism and address the IU been which has limitedly studied in the FCR literature. The current study's findings have also contributed to the clinical field by highlighting the importance of incorporating breast cancer survivors' metacognitions and IU in FCR intervention programs.

Scanxiety and Fear of Recurrence in Young Adult Female Breast and Gynaecological Cancer Survivors: Investigating Shared Mechanisms

BACKGROUND

Adolescent and young adult (AYA) females are vulnerable to psychological sequelae following cancer diagnosis and treatment. Fear of cancer recurrence (FCR) is well-documented in cancer survivors, however AYA survivors of breast and gynaecological cancers are less well-studied. Moreover, little is known about scan-related fears and anxiety ('scanxiety') in survivors of any age group.

AIMS

This study aimed to assess demographic, medical, and quality-of-life correlates of FCR and scanxiety in AYA female breast and gynaecological cancer survivors post-treatment. Additionally, we explored potential shared mechanisms of FCR and scanxiety, including intolerance of uncertainty, bodily threat monitoring, and perceived stress.

METHODS

AYA breast and gynaecological cancer survivors (N = 115) completed measures of FCR, scanxiety, intolerance of uncertainty, bodily threat monitoring, perceived stress, and quality of life. Bivariate associations and a structural equation model explored relationships between these variables.

RESULTS

Both FCR and scanxiety were prevalent, with 84% reporting clinically meaningful FCR and 38% reporting severe FCR. Higher FCR and scanxiety were both associated with poorer quality of life. FCR and scanxiety were moderately associated but not entirely overlapping. Intolerance of uncertainty, bodily threat monitoring, and perceived stress were significantly correlated with both FCR and scanxiety. The structural equation model indicated that bodily threat monitoring is a plausible intermediate variable linking intolerance of uncertainty and FCR, but not scanxiety.

CONCLUSIONS

FCR and scanxiety are common in AYA survivors of breast and gynaecological cancers, with potentially distinct underlying mechanisms. Interventions targeting intolerance of uncertainty and bodily threat monitoring may reduce FCR, while further research is needed to identify therapeutic targets for scanxiety.

Understanding mental health in breast cancer from screening to Survivorship: an integrative phasic Model and tool

Integrative models of mental illness and health in psycho-oncology are aimed at all types of cancer, although the patients' experiences and issues may vary. This review summarizes the different theories and models of mental illness and health pertaining to the breast cancer experience and proposes an integrative phasic model applicable to the breast cancer trajectory. Five databases were searched for studies related to breast cancer mental health and illness theories and models. The PRISMA checklist form was used to extract the essential information from the included studies. Eleven theories and models on the experience of breast cancer were found. The integrative model based on these theories and models illustrates that the breast cancer experience is conceptualized as a trajectory with seven landmark 'events', each associated with a pathogenic 'challenge' leading to six possible 'symptoms', 1) psychological distress with anxious features, 2) psychological distress with depressive features, 3) non-specific distress 4) psychological distress with trauma-related features 5) low health-related quality of life, and 6) fear of recurrence. The Breast Cancer Psychological Integrative Phasic Model is supported by a simple clinical tool (BreastCancerPsych - Integrative Clinical Tool) that serves as a valuable resource throughout the care trajectory. These integrative phasic model and clinical tool are designed to help mental health clinicians formulate treatments that are tailored to the needs of their patients, especially for trajectories that are not marked by resilience.

It is time to address fear of cancer recurrence in family caregivers: protocol for the feasibility and acceptability of a randomized pilot study of the online version of the Family Caregiver-Fear Of Recurrence Therapy (FC-FORT)

BACKGROUND

Fear of cancer recurrence (FCR) is common, persistent, and is associated with lower quality of life, impaired functioning, and psychological distress in cancer patients. Studies suggest that family caregivers of cancer patients experience equal or greater levels of FCR than patients themselves. In the past 5 years, several interventions have demonstrated their ability to reduce FCR among cancer patients and in patient-caregiver dyads. However, to date, no intervention exists to individually target family caregiver's FCR. The aims of the proposed pilot study are to (1) assess the feasibility and acceptability of the newly adapted Family Caregiver-Fear Of Recurrence Therapy (FC-FORT) intervention to inform a larger randomized control trial study, and (2) estimate the clinical significance of FC-FORT. Initial evaluation of FC-FORT revealed high user satisfaction and usability.

METHODS

A parallel, two-group, pilot randomized controlled trial comparing FC-FORT to a waitlist control (care as usual) will be conducted. Participant inclusion criteria are (a) women family caregivers taking care of adult cancer patients (no recurrence), (b) experiencing clinical levels of FCR, (c) access to a computer/internet connection, and (d) living in Canada. Participants (n = 36) will be recruited at Ottawa and Toronto hospitals, previous study participant pools, through social media and community partners across Canada. Participants in the intervention group will complete the FC-FORT intervention (7 consecutive weeks of virtual group therapy and homework). Participants in the control group will be offered the intervention after their participation in the study. All participants will be asked to complete questionnaire packages at baseline (T0), immediately post-intervention (7 weeks; T1) and at 3-months post-intervention (T2). Feasibility (e.g., recruitment, allocation, fidelity), acceptability (e.g., dropout, completion, satisfaction) and clinical significance of secondary outcomes will be evaluated (i.e., FCR illness uncertainty). Participants in the intervention group will be asked to complete measures of group cohesion and therapeutic alliance and take part in a semi-structured exit interview exploring their overall experience with FC-FORT.

DISCUSSION

This project will evaluate the acceptability and feasibility of the newly adapted FC-FORT to inform a larger trial.

The relationship between uncertainty and fear of disease progression among newly diagnosed cancer patients: the mediating role of intolerance of uncertainty

BACKGROUND

One of the most prevalent unmet needs among cancer patients is the fear of disease progression (FoP). This cross-sectional study aimed to identify the relationships among uncertainty in illness (UI), intolerance of uncertainty (IU), and FoP among newly diagnosed cancer patients and to verify the mediating role of IU in the relationship between UI and FoP.

METHODS

A total of 202 newly diagnosed cancer patients (male: 105, 51.98%; mean age: 47.45 ± 14.8 years; lung cancer: 49, 24.26%) were recruited by convenience sampling. The patients completed a homemade questionnaire that assessed demographic characteristics, the Fear of Progression Questionnaire-Short Form, the Mishel Uncertainty in Illness Scale, and the Intolerance of Uncertainty Scale.

RESULTS

The prevalence of FoP among newly diagnosed cancer patients was 87.62%, and the prevalences of high, medium, and low levels of UI were 15.84%, 73.27%, and 10.89%, respectively. The mean score on the Intolerance of Uncertainty Scale was 41.19 ± 10.11. FoP among newly diagnosed cancer patients was positively correlated with UI (r = 0.656, P < 0.001) and IU (r = 0.711, P < 0.001). Moreover, IU was positively correlated with UI (r = 0.634, P < 0.001). IU partially mediated the effect of UI on FoP, accounting for 47.60% of the total effect.

CONCLUSIONS

Newly diagnosed cancer patients have a high prevalence of FoP. UI can directly or indirectly affect FoP through the mediating role of IU. Healthcare professionals can help newly diagnosed cancer patients mitigate their FoP by reducing IU in light of UI.

Fear of Cancer Recurrence in Adult Survivors of Childhood Cancer

Importance

Fear of cancer recurrence is common among survivors of adult-onset cancer and associated with increased distress, functional impairment, and health care utilization. However, little is known about the prevalence and risk factors of fear of cancer recurrence among adult survivors of childhood cancer who are also at high risk for subsequent malignant neoplasms.

Objective

To characterize the prevalence of and risk factors for clinically significant fear of cancer recurrence in adult survivors of childhood cancer.

Design, Setting, and Participants

This cross-sectional investigation included participants recruited from the Childhood Cancer Survivor Study, a retrospective cohort study of long-term childhood cancer survivors treated at 31 institutions between 1970 and 1999 across North America. Participants were recruited and completed psychosocial measures via online survey between October 2018 and April 2019. Cancer and treatment-related variables were abstracted from medical records. Data were analyzed from May 2023 to July 2024.

Main Outcomes and Measures

Clinically significant fear of cancer recurrence was assessed via the Fear of Cancer Recurrence Inventory-Short Form. Poisson regression models estimated prevalence ratios (PRs) with 95% CIs adjusted for age and sex to examine the associations of demographic, disease, treatment, and psychosocial variables with fear of cancer recurrence.

Results

The final sample included 229 adult survivors of childhood cancer (115 female [50.2%]; mean [SD] age, 39.6 [9.9] years; mean [SD] time since diagnosis, 31.7 [8.4] years). Among survivors, 38 (16.6%; 95% CI, 11.6%-21.6%) reported clinically significant fear of cancer recurrence, and an additional 36 (15.7%) reported high fear of cancer recurrence. Clinically significant fear of cancer recurrence was associated with unemployment (PR, 2.5; 95% CI, 1.3-4.8), presence of neurologic chronic health conditions (PR, 3.3; 95% CI, 1.8-6.1), treatment with pelvic radiation (PR, 2.9; 95% CI, 1.5-5.6), and amputation or limb sparing surgery (PR, 2.4; 95% CI, 1.2-4.9). Higher risk of clinically significant fear of cancer recurrence was also associated with having either elevated anxiety or depression (PR, 2.6; 95% CI, 1.2-5.9), having both elevated (PR, 3.2; 95% CI, 1.2-8.4), and perceived poor health status (PR, 3.0; 95% CI, 3.1-9.7).

Conclusions and Relevance

Decades following treatment, one-third of childhood cancer survivors in this study reported elevated fear their cancer will recur or a subsequent malignant neoplasm will develop. Findings suggest that fear of cancer recurrence should be routinely screened, and clinically significant symptoms intervened upon as a part of survivorship care.

Associations between empirically proportionate and disproportionate fears of cancer recurrence and anxiety and depression in uveal melanoma survivors: Five-year prospective study

OBJECTIVE

Fear of cancer recurrence (FCR) may develop into elevated anxiety or depression symptoms, but few risk factors for this development are known. Objective recurrence risk estimation is possible in some cancers. Using theories of risk communication and phobias, we examined whether the proportionality of FCR to known objective recurrence risk influences the development of anxiety and depression symptoms.

METHOD

Uveal melanoma (UM) patients can opt for reliable prognostic testing. Patients experience either a 'good' or 'poor' prognostic outcome, whereby 10-year mortality due to metastatic disease is, respectively, low or high. In a five-year prospective study of a consecutive sample of 589 UM survivors, we used random intercept cross lagged panel analyses to examine whether proportionality differentially influences whether FCR progresses to anxiety and depression.

RESULTS

Positive cross paths predicting anxiety from FCR were stronger in the poor prognosis group than the good prognosis and not tested groups. Prognostic group differences were not evident for depression.

CONCLUSIONS

FCR was more likely to progress to elevated anxiety symptoms when proportionate to the known objective recurrence risk. Objective evidence may play a prominent role in the development and structure of fear because it assumes a high epistemic weight that activates a wide range of emotional and cognitive responses. Interventions that assist survivors to tolerate FCR in the presence of higher recurrence risks may be important in reducing anxiety symptoms.

Fear of cancer recurrence in breast cancer survivors carrying a BRCA1 or 2 genetic mutation : a cross-sectional study

BACKGROUND

Fear of cancer recurrence (FCR) affects virtually all patients who have been treated for cancer, to varying degrees. Breast cancer survivors who carry a BRCA1 or BRCA2 gene mutation are at high risk of cancer recurrence. No study has yet assessed FCR specifically in this population.

OBJECTIVES

This cross-sectional study, conducted in women who were treated for breast cancer and carrying a BRCA1/2 mutation, aimed to: (1) assess the mean level of FCR and estimate the proportion of patients with clinical levels of FCR; (2) examine the relationships between FCR and selected psychological variables (e.g., avoidance, intolerance to uncertainty) and quality of life; (3) explore whether FCR levels vary as a function of the past preventive treatment received; and (4) to assess the associations between FCR and the presence of decisional conflict or regret regarding the various preventive options.

METHOD

Participants were recruited through an e-mail sent to an oncogenetic network mailing list (Réseau ROSE). Participants were asked to complete a battery of questionnaires online assessing FCR and other psychological and quality of life variables.

RESULTS

A total of 89 women completed the survey. Most participants had undergone a preventive mastectomy (62.9%) and a preventive salpingo-oophorectomy (75.3%) at the time of the study. The mean Fear of Cancer Recurrence Inventory-severity score was 16.8, which exceeds the clinical cut-off score of 13, and 70.8% of the participants showed a clinical level of FCR. FCR was significantly associated with higher levels of anxiety and depression, and higher avoidance and intolerance of uncertainty, but not with quality of life. No significant difference was observed on the total FCR score between women who had received preventive surgery (mastectomy and/or salpingo-oophorectomy) and those considering it, and those not considering it. The association was significant between higher FRC scores and greater decisional conflicts and regrets about choosing to undergo preventive surgery.

CONCLUSION

These data suggest that FCR is a significant problem for breast cancer survivors carrying a BRCA1/2 genetic mutation, even after undergoing a prophylactic surgery. This highlights the importance of providing these women with specific psychological intervention focusing on FCR.

Afraid and tired: A longitudinal study of the relationship between cancer-related fatigue and fear of cancer recurrence in long-term cancer survivors

OBJECTIVE

Cancer-related fatigue (CRF) and fear of cancer recurrence (FCR) are two common concerns experienced by cancer survivors. However, the relationship between these two concerns is poorly understood, and whether CRF and FCR influence each other over time is unclear.

METHODS

Data were from a national, prospective, longitudinal study, the American Cancer Society's Study of Cancer Survivors-I (SCS-I). Surveys were completed by 1395 survivors of 10 different cancer types at three time-points, including assessment 1.3 years (T1), 2.2 years (T2) and 8.8 years (T3) following their cancer diagnosis. CRF was assessed using the fatigue-inertia subscale of the Profile of Mood States, and FCR by the FCR subscale of the Cancer Problems in Living Scale. Multiple group random intercepts cross-lagged panel models investigated prospective associations between CRF and FCR.

RESULTS

For younger participants (at or below median age of 55 years, n = 697), CRF at T1 and T2 marginally and significantly predicted FCR at T2 and T3, respectively, but no lagged effects of FCR on subsequent CRF were observed. Cross-lagged effects were not observed for survivors over 55 years of age.

CONCLUSION

Both CRF and FCR are debilitating side effects of cancer and its treatments. Given that CRF may be predictive of FCR, it possible that early detection and intervention for CRF could contribute to lowering FCR severity.

The Heterogeneity of Symptom Burden and Fear of Progression Among Kidney Transplant Recipients: A Latent Class Analysis

Purpose

Kidney transplant recipients (KTRs) may experience symptoms that increase their fear of progression (FoP), but a dearth of research examines the issue from a patient-centered perspective. Our study aimed to first determine the category of symptom burden, then to explore the differences in characteristics of patients in different subgroups, and finally to analyze the impact of symptom subgroup on FoP.

Patients and Methods

Sociodemographic and Clinical Characteristics, Symptom Experience Scale, and Fear of Progression Questionnaire-Short Form were used. Latent class analysis was used to group KTRs according to the occurrence of symptoms. We used multivariate logistic regression to analyze the predictors of different subgroups. The differences in FoP among symptom burden subgroups were analyzed by hierarchical multiple regression.

Results

Three subgroups were identified, designated all-high (20.5%), moderate (39.9%), and all-low (39.6%) according to their symptom occurrence. Multivariate logistic regression showed that gender, post-transplant time, per capita monthly income, and hyperuricemia were the factors that distinguished and predicted the all-high subgroup (P < 0.05). Hierarchical multiple regression showed that symptom burden had a significant effect on FoP (class1 vs class3: β = 0.327, P < 0.001; class2 vs class3: β = 0.104, P = 0.046), explaining the 8.0% variance of FoP (ΔR2 = 0.080).

Conclusion

KTRs generally experience moderate or low symptom burden, and symptom burden is an influencing factor in FoP. Identifying the traits of KTRs with high symptom burden can help clinicians develop targeted management strategies and ease FoP of KTRs.

Core and bridge symptoms of demoralization in Chinese female cancer patients: a network analysis

Objective

In this study, we explore the core and bridge symptoms of demoralization in female cancer patients in China, and provide a basis for precise psychological intervention among female cancer patients.

Methods

This study used a cross-sectional survey. Participants were recruited from three third-class hospitals in Jiangsu Province from June 2022 to June 2023 using the convenience sampling method. The severity of each symptom of demoralization was investigated in female cancer patients using the Demoralization Scale (DS). Network analysis was performed using the R language to identify core and bridge symptoms in the network and further explore some characteristic edge connections in the network.

Results

The network structure model of demoralization had strong accuracy and stability. In the network, the symptoms with the highest strength centrality were "Discouragement" (C3, strength=2.19), "No self-worth" (A3, strength=1.21), "Don't want to live" (A5, strength=1.20), "Hopeless" (D4, strength=0.81), and "Vulnerability" (B3, strength=0.74), respectively. The bridge strength analysis identified "Hopeless" (D4, bridge strength=0.92), "Discouragement" (C3, bridge strength=0.85), "No self-worth" (A3, bridge strength=0.75), "Poor spirits" (E2, bridge strength=0.71), and "Vulnerability" (B3, bridge strength=0.69) as the bridge symptoms. The strongest edge connections of all dimensions were "No self-worth" and "Worthless" (A3-E6, edge weighting=0.27), "Poor spirits" and "Loss of emotional control" (E2-D1, edge weighting=0.22), "Discouragement" and "Vulnerability" (C3-B3, edge weighting=0.14), and "Hopeless" and "No meaning of survival" (D4-A4, edge weighting=0.12).

Conclusion

"Discouragement (C3)", "No self-worth (A3)", "Hopeless (D4)", and "Vulnerability (B3)" are both core symptoms and bridge symptoms. These symptoms can not only trigger a patient's demoralization but also stimulate more severe symptom clusters through interactions. The early recognition of and intervention regarding these symptoms could be important for the prevention and treatment of demoralization among female cancer patients.

Fear of recurrence in women with ovarian cancer: A qualitative evidence synthesis

PURPOSE

Approximately 80% of ovarian cancers recur after first-line treatments. Women with ovarian cancer (OC) are therefore particularly vulnerable to experiencing fear of cancer recurrence (FCR). This study aimed to synthesise experiences of fear of cancer recurrence among women living with ovarian cancer.

METHOD

A qualitative evidence synthesis (QES) was conducted in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. A systematic search of seven databases was undertaken to identify all available qualitative research exploring fear of cancer recurrence in women with OC. Thematic synthesis of extracted data from included studies was undertaken and managed in NVivo.

RESULTS

Twenty-two papers reporting on eighteen studies were included in the synthesis. Three main themes were developed (triggers, responses, and coping) and included ten subthemes. FCR was triggered by factors relating to awareness of prognosis, treatment, and negative communication. Women responded to FCR by performing body checking and protecting their families. FCR led to adverse effects on women's wellbeing as it exacerbated uncertainty about their future. Women attempted to cope with FCR through seeking support, regaining control, and redirecting negative thoughts and actions.

CONCLUSIONS

Women use a variety of approaches to manage their fear of recurrence. Further research on the most appropriate interventions for FCR tailored specifically to the needs of women with OC is needed.

Disruptions in Cancer Care Due to the COVID-19 Pandemic and Fear of Cancer Recurrence in Women with Breast Cancer: A Mixed-Methods Study

OBJECTIVE

This study investigated if fear of cancer recurrence (FCR) levels and the proportion of women having a clinical level of FCR differed by whether women had or had not experienced disruptions in their cancer tests and treatments due to the pandemic.

METHODS

We conducted a mixed-methods study between November 2020 and March 2021 among women diagnosed with breast cancer in the previous five years at the time of their entry in the study. Women completed a questionnaire online assessing disruptions in breast cancer tests and treatments due to the pandemic and the severity subscale of the Fear of Cancer Recurrence Inventory. Semi-structured interviews were also conducted with a subsample of 24 participants and were thematically analyzed.

RESULTS

The proportion of patients with a clinical level of FCR was significantly higher among those who experienced the postponement or cancellation of diagnostic and disease progression tests (e.g., blood tests, X-rays, or magnetic resonance imaging; adjusted PR = 1.27 95% CI = 1.13-1.43). Qualitative findings suggest that FCR was exacerbated by the pandemic context. In particular, perceived or actual barriers to care access due to the pandemic were identified as significant FCR-enhancing factors.

CONCLUSIONS

These results highlight the need to keep diagnostic and progression tests as timely as possible to prevent increases in FCR levels and offer counselling about FCR when postponing or cancellation are inevitable.

Fear of cancer recurrence in breast cancer survivors carrying a BRCA1/2 mutation: A qualitative study

BACKGROUND

There is preliminary evidence suggesting that FCR is a major problem for breast cancer survivors carrying a BRCA1/2 mutation. The goal of this qualitative study, conducted among women who were treated for breast cancer, was to provide a deeper understanding of how FCR is experienced in the context of a genetic predisposition to breast cancer.

METHOD

Three focus groups (90-110 min) were conducted with 19 breast cancer survivors carrying a BRCA1/2 mutation. The semistructured interview probed FCR level and impact, the role FCR played in the decision to have a prophylactic bilateral mastectomy and/or salpingo-oophorectomy, the effect that surgery had on FCR, and the relevance of offering a psychological intervention targeting FCR to this population.

RESULTS

Findings indicated that FCR was a significant issue in these women, even though a majority had undergone a prophylactic surgery. Patients strongly affirmed the need to develop and provide access to FCR interventions that are specifically adapted to the needs of this group.

DISCUSSION

These results suggest that, although being the most effective medical option to reduce the actual risk of local recurrence (or second breast cancer), prophylactic surgery only partially reduces FCR. A psychological intervention targeting specifically FCR would be an appropriate complement to preventive surgery.

Trajectories of fear of cancer recurrence and its influence factors: A longitudinal study on Chinese newly diagnosed cancer patients

OBJECTIVE

The fear of cancer recurrence (FCR) is an ongoing and common psychological problem faced by cancer patients. The objective of this study was to explore the variation trend of FCR and its influencing factors in Chinese newly diagnosed cancer patients from admission to 2 months after discharge. Demographic and tumor characteristics, as well as experiential avoidance (EA), were used as predictors.

METHOD

A longitudinal design and a consecutive sampling method were used to select 266 newly diagnosed cancer patients admitted to a tertiary cancer hospital in China from July to December 2022. Measurements of FCR and EA were obtained at admission (T1), 1 month after discharge (T2), and 2 months post-discharge (T3). Generalized estimating equations were used to identify factors associated with FCR for longitudinal data analysis.

RESULTS

A total of 266 participants completed the follow-up. Both FCR and EA scores of patients with newly diagnosed cancer showed a significant trend of first increasing and then decreasing at baseline and follow-up (p < 0.001). The junior secondary and less education level, rural residence, advanced tumor and high EA level were risk factors for higher FCR.

CONCLUSIONS

Our findings suggest that the FCR levels of most newly diagnosed cancer patients in China are different at the three time points and affected by different factors, with the highest level at 1 month after discharge. These results have significant implications for future identifying populations in need of targeted intervention based on their FCR trajectories.

Familial aspects of fear of cancer recurrence: current insights and knowledge gaps

Fear of cancer recurrence is fear or worry about cancer recurrence or progress. Fear of recurrence can impact patients' quality of life and wellbeing. Cancer survivors' families support them practically and emotionally, making them a vital supplement for official healthcare. Given the well-established important role of the family in dealing with cancer, we compiled the studies that examined the relationship between family-related factors and fear of cancer recurrence (FCR) among cancer survivors (CSs). One of the foremost studies in this field is the FCR model presented by Mellon and colleagues, which included concurrent family stressors and family-caregiver FCR as factors linked to survivor FCR. Our goal was to prepare the ground for a family-based model of FCR that is more comprehensive than the one proposed by Mellon et al. sixteen years ago. The studies included those with samples of adult cancer survivors from different regions of the world. Most of the studies we reviewed are cross-sectional studies. We categorized family-related factors associated with survivor FCR into partner-related factors, including subgroups of disclosure to partner, cognitions of partner, and partner's sources of support; parenthood-related factors, including having children and parenting stress; family-related factors, including living situation, family history of cancer, family's perception of the illness, and family characteristics; and social interactions including social support, disclosure, social constraints, and attitudes of others. This review sheds light on how significant others of cancer survivors can affect and be affected by cancer-related concerns of survivors and emphasizes the necessity of further investigation of family-related factors associated with FCR.

Supportive care needs of breast cancer survivors with different levels of fear of cancer recurrence: A cross-sectional survey study

PURPOSE

To examine the supportive care needs of breast cancer survivors with nonclinical, subclinical, or clinical fear of cancer recurrence.

METHODS

In this cross-sectional study, 385 breast cancer survivors consented and completed a set of online questionnaires. Supportive care needs were assessed by using the 34-item Supportive Care Needs Survey. Fear of cancer recurrence was assessed by using the Fear of Cancer Recurrence Inventory.

RESULTS

One hundred eighty-four (47.8%) participants reported nonclinical fear of cancer recurrence, 147 (38.2%) reported subclinical fear of cancer recurrence, and 54 (14.0%) reported clinical fear of cancer recurrence. Higher levels of fear of cancer recurrence were associated with higher levels of supportive care needs in five domains (β = 0.30-0.60, P < 0.001) after adjusting for places of residence, education, motherhood, and time since diagnosis. Among participants with nonclinical fears of cancer recurrence, the most common needs were in the 'Health care system/Information' domain (50.5%). Among participants with subclinical or clinical fear of cancer recurrence, the most common needs were in the 'Psychological' domain (85.7% and 96.3%, respectively).

CONCLUSION

Fear of cancer recurrence was associated with supportive care needs. The most common needs among participants with subclinical or clinical fears of cancer recurrence were psychological needs.

It's time to address fear of cancer recurrence in family caregivers: usability study of an virtual version of the Family Caregiver-Fear Of Recurrence Therapy (FC-FORT)

Background

Family caregivers of cancer survivors experience equal or greater levels of fear of cancer recurrence (FCR) than survivors themselves. Some interventions have demonstrated their ability to reduce FCR among cancer survivors and dyads (patient and caregivers). However, to date, no validated intervention exists to focus solely on family caregiver's FCR.

Objectives

This study aimed to (1) adapt the evidence-based in-person Fear Of Recurrence Therapy (FORT) for family caregivers (referred here in as FC-FORT) and to a virtual delivery format and (2) test its usability when offered virtually.

Methods

The adaptation of FC-FORT was overseen by an advisory board and guided by the Information Systems Research Framework. Following this adaptation, female family caregivers and therapists were recruited for the usability study. Participants took part in 7 weekly virtual group therapy sessions, a semi-structured exit interview and completed session feedback questionnaires. Therapists were offered a virtual training and weekly supervision. Fidelity of treatment administration was assessed each session. Quantitative data were analyzed using descriptive statistics. Exit interviews were transcribed verbatim using NVivo Transcription and coded using conventional content analysis. Results were presented back to the advisory board to further refine FC-FORT.

Results

The advisory board (n = 16) met virtually on 7 occasions to adapt FC-FORT (i.e., patient manuals, virtual format) and discuss recruitment strategies. Minor (e.g., revised text, adapted materials to virtual format) and major adaptations (e.g., added and rearranged sessions) were made to FC-FORT and subsequently approved by the advisory board. Four family caregivers and three therapists took part in the first round of the usability testing. Six family caregivers and the same three therapists took part in the second round. Overall, participants were very satisfied with FC-FORT's usability. Qualitative analysis identified 4 key themes: usability of FC-FORT, satisfaction and engagement with content, group cohesion, and impact of FC-FORT. All participants indicated that they would recommend FC-FORT to others as is.

Conclusions

Using a multidisciplinary advisory board, our team successfully adapted FC-FORT and tested its usability using videoconferencing. Results from this study indicate that the efficacy and acceptability of FC-FORT are now ready to be tested in a larger pilot study.

Caregiver fear of cancer recurrence: A systematic review and meta-analysis of quantitative studies

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.

The role of uncertainty intolerance in adjusting to long-term physical health conditions: A systematic review

Long-term physical health conditions (LTPHCs) are associated with poorer psychological well-being, quality of life, and longevity. Additionally, individuals with LTPHCs report uncertainty in terms of condition aetiology, course, treatment, and ability to engage in life. An individual's dispositional ability to tolerate uncertainty-or difficulty to endure the unknown-is termed intolerance of uncertainty (IU), and may play a pivotal role in their adjustment to a LTPHC. Consequently, the current review sought to investigate the relationship between IU and health-related outcomes, including physical symptoms, psychological ramifications, self-management, and treatment adherence in individuals with LTPHCs. A systematic search was conducted for papers published from inception until 27 May 2022 using the databases PsycINFO, PubMed (MEDLINE), CINAHL Plus, PsycARTICLES, and Web of Science. Thirty-one studies (N = 6,201) met the inclusion criteria. Results indicated that higher levels of IU were associated with worse psychological well-being outcomes and poorer quality of life, though impacts on self-management were less clear. With the exception of one study (which looked at IU in children), no differences in IU were observed between patients and healthy controls. Although findings highlight the importance of investigating IU related to LTPHCs, the heterogeneity and limitations of the existing literature preclude definite conclusions. Future longitudinal and experimental research is required to investigate how IU interacts with additional psychological constructs and disease variables to predict individuals' adjustment to living with a LTPHC.

Validation of the Lee-Jones theoretical model of fear of cancer recurrence among breast cancer survivors using a structural equation modeling approach

OBJECTIVE

The Lee-Jones model posits that antecedent individual and interpersonal factors predicate the development of fear of cancer recurrence (FCR) through cognitive and emotional processing, which further to behavioral, emotional, and/or physiological responses. We analyzed data from FoRtitude, a FCR intervention grounded in the Lee-Jones FCR model, to evaluate associations between FCR antecedents, resources (e.g., breast cancer self-efficacy, BCSE) and psychological and behavioral consequences.

METHODS

Women with breast cancer who completed treatment and reported clinically elevated levels of FCR were randomized into a 4-week online psychosocial intervention or contact control group. We assessed BCSE, FCR, and physical activity, anxiety and depression, or symptoms at baseline, 4 and 8 weeks. Separate structural equation models were constructed with both baseline data and change scores (baseline-8 weeks) to examine the pathways linking BCSE, FCR and: (1) physical activity; (2) anxiety and depression; and (3) symptoms (fatigue, sleep disturbance, cognitive concerns).

RESULTS

At baseline, higher levels of BCSE were associated with lower levels of FCR. Higher FCR was associated with worse psychological effects and symptoms but not behavioral response. Change models revealed that an increase in BCSE was associated with a decrease in FCR at 8-week assessment, which was associated with reductions in psychological effects. A change in BCSE was also directly associated with reductions in psychological effects.

CONCLUSIONS

Results support the Lee-Jones model as a foundation for FCR interventions among breast cancer survivors. Replicability among varied populations is needed to examine effects on behavioral outcomes of FCR such as health care utilization.

Fear of cancer recurrence and adverse cancer treatment outcomes: predicting 2- to 5-year fear of recurrence from post-treatment symptoms and functional problems in uveal melanoma survivors

OBJECTIVE

The fear of cancer recurrence (FCR) in later survivorship can lead to poorer mental health, quality of life and physical and functional recovery. Later-occurring FCR may be a consequence of late-emerging physical symptoms and functional problems from cancer or its treatment. Based on the self-regulation model, we predicted that persistent or escalating symptoms and functional problems would prospectively predict FCR observed 2-5 years after diagnosis and treatment.

METHODS

This is a five-year study of 708 uveal melanoma (UM) patients, measuring self-reported visual and ocular symptoms, functional problems and FCR at 6, 12, 24, 36, 48 and 60 months post-diagnosis. A mixed measures design over four levels with observations staggered to represent prospective prediction. Criterion variables were FCR at 24, 36, 48 and 60 months. Predictors were symptom and function scores measured at the previous two observations to FCR. Controls were FCR measured at the previous observation to the criterion FCR measure and demographic, clinical and treatment variables.

RESULTS

Linear mixed modelling showed that FCR was uniquely predicted by enduring symptoms, those that emerged two observations previously, but not symptoms arising at the previous observation. FCR was predicted by functional problems, which emerged in the observation prior to FCR, but not the observation previous to that.

CONCLUSIONS

Persistent or emerging post-treatment symptoms and functional limitations are probable risk factors for late-occurring FCR in UM survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Monitoring symptoms and functional limitations assists in identifying at-risk survivors and targeting preventive interventions. Self-regulation theory suggests that helping survivors to more realistically appraise symptoms and functional problems may prevent FCR.

Fear of cancer recurrence as a pathway from fatigue to psychological distress in mothers who are breast cancer survivors

Fatigue is prevalent and pervasive among breast cancer survivors. Mothers are particularly susceptible to fatigue due to the ongoing demands of their caring role. While fatigue has been associated with psychological distress in prior research, the pathway by which fatigue translates into psychological distress is unclear. Given the theoretical and empirical links between fatigue, fear of cancer recurrence (FCR) and psychological distress, the role of FCR in mediating the relationship between fatigue and psychological distress in mothers who are breast cancer survivors was investigated. Ninety-two mothers who were breast cancer survivors completed the Depression, Anxiety and Stress Scale, PROMIS-Cancer Fatigue Short Form and Concerns About Cancer Recurrence scale in an online survey. Mediation analysis via PROCESS was used to examine whether fatigue predicted depression, anxiety or stress through FCR. Fear of cancer recurrence mediated the relationships between fatigue and anxiety and fatigue and stress, while fatigue directly predicted depression. This study highlights FCR as a potential pathway to anxiety and stress in response to ongoing fatigue, and as a mechanism of action to reduce psychological distress among mothers who are breast cancer survivors. Future research examining this pathway from fatigue to psychological distress should also explore the nature of mothers' fears about their cancer recurring.

Perfectionism, intolerance of uncertainty and coping in relation to fear of cancer recurrence in breast cancer patients

OBJECTIVE

Improved medical treatment has led to an increased cohort of cancer survivors. The prevalence of emotional problems in this group is high, with fear of cancer recurrence (FCR) being among the most prevalent and distressing conditions. In order to gain more insight in the psychological mechanisms playing a role in levels of FCR, this study examined the relationship between perfectionism and FCR in breast cancer patients, as well as the mediating role of intolerance of uncertainty (IU) and coping in this relationship. In order to contribute to a more comprehensive understanding of the mechanisms related to the experience of FCR in breast cancer patients, the purpose of the present study is to investigate the relationship between perfectionism and FCR, with IU and coping strategies as possible mediating factors.

METHODS

Validated Dutch versions of the FCR Inventory, the Multidimensional Perfectionism Scale, the Intolerance of Uncertainty Scale and the Utrechtse Coping List were filled out by 146 breast cancer patients, at least one year after (finishing) medical treatment. Correlation analyses were conducted to administer the associations between FCR, perfectionism, IU, coping and demographic/medical variables. PROCESS was used to examine mediation mechanisms.

RESULTS

A significant correlation was found between perfectionism and FCR (r = 0.19, p = 0.024). IU was found to mediate the relationship between perfectionism and FCR. In contrast, coping style did not emerge as a significant mediating factor.

CONCLUSIONS

This study shows that intolerance of uncertainty mediates the relationship between perfectionism and FCR. Psychological interventions targeting FCR may benefit from incorporating specific modules on dealing with uncertainty. Future research is necessary to further increase understanding of the mechanisms that play a role in FCR, in order to optimize and personalize psychological treatment for cancer patients with this type of emotional distress.

The fear of cancer recurrence and progression in patients with pancreatic cancer

PURPOSE

It is plausible that patients with pancreatic cancer experience fear of tumor recurrence or progression (FOP). The aim of this study was to compare FOP in patients with pancreatic cancer treated with surgical resection, palliative systemic treatment, or best supportive care (BSC) and analyze the association between quality of life (QoL) and FOP and the effect of FOP on overall survival (OS).

METHODS

This study included patients diagnosed with pancreatic cancer between 2015 and 2018, who participated in the Dutch Pancreatic Cancer Project (PACAP). The association between QoL and WOPS was assessed with logistic regression analyses. OS was evaluated using Kaplan-Meier curves with the log-rank tests and multivariable Cox proportional hazard analyses adjusted for clinical covariates and QoL.

RESULTS

Of 315 included patients, 111 patients underwent surgical resection, 138 received palliative systemic treatment, and 66 received BSC. Patients who underwent surgical resection had significantly lower WOPS scores (i.e., less FOP) at initial diagnosis compared to patients who received palliative systemic treatment or BSC only (P < 0.001). Better QoL was independently associated with the probability of having a low FOP in the BSC (OR 0.95, 95% CI 0.91-0.98) but not in the surgical resection (OR 0.97, 95% CI 0.94-1.01) and palliative systemic treatment groups (OR 0.97, 95% CI 0.94-1.00). The baseline WOPS score was not independently associated with OS in any of the subgroups.

CONCLUSION

Given the distress that FOP evokes, FOP should be explicitly addressed by health care providers when guiding pancreatic cancer patients through their treatment trajectory, especially those receiving palliative treatment or BSC.

Trajectories of fear of cancer recurrence in young breast cancer survivors

BACKGROUND

Fear of cancer recurrence (FCR) is more intense in younger women. Because FCR is a powerful determinant of quality of life, identifying those at risk for persistently elevated FCR can inform timing of interventions.

METHODS

A total of 965 women with stage 0 to stage III breast cancer enrolled in the Young Women's Breast Cancer Study, a prospective cohort of women diagnosed with breast cancer at age ≤40 years, completed the 3-item Lasry Fear of Recurrence Index. Group-based trajectory modeling was used to classify distinct FCR patterns from baseline through 5 years post-diagnosis. Multinomial logistic regression was used to identify patient, disease, and treatment characteristics associated with each trajectory.

RESULTS

Five FCR trajectories were identified with the majority of participants having moderate (33.1%) or high FCR (27.6%) that improved over time. A total of 6.9% participants had moderate FCR that worsened, whereas 21.7% had high FCR at baseline that remained high throughout. In the fully adjusted multinomial model, stages II and III (vs stage I) were associated with lower odds (of being in the high/stable trajectory). White (vs non-White) were associated with higher odds of being in a trajectory that improved over time.

CONCLUSIONS

Although FCR improves over time for many young women with breast cancer, approximately one-third had FCR that was severe and did not improve or worsened over 5 years after diagnosis. Ongoing monitoring is warranted, with early referral to mental health professionals indicated for those at highest risk for unresolved FCR.

LAY SUMMARY

Fear of recurrence is common among young women with breast cancer. The authors followed a large cohort of young women diagnosed with breast cancer when they were 40 years of age and younger, and found 5 distinct trajectories that show moderate and severe fears do not always improve over time and may require targeted mental health intervention.

A systematic mixed studies review of fear of cancer recurrence in families and caregivers of adults diagnosed with cancer

PURPOSE

Fear of cancer recurrence (FCR) may be equally prevalent, persistent and burdensome in cancer caregivers as in survivors. This systematic review evaluated FCR prevalence, severity, correlates, course, impact and interventions in cancer caregivers.

METHODS

Electronic databases were searched from 1997 to May 2021. Two reviewers identified eligible peer-reviewed qualitative or quantitative studies on FCR in adult caregivers or family members of adult cancer survivors. The risk of bias was assessed using the Cochrane Risk of Bias tools for randomised and non-randomised studies and the Mixed-Methods Appraisal Tool. A narrative synthesis and thematic synthesis occurred on quantitative and qualitative studies, respectively.

RESULTS

Of 2418 papers identified, 70 reports (59 peer-reviewed articles, 11 postgraduate theses) from 63 studies were included. Approximately 50% of caregivers experienced FCR. Younger caregivers and those caring for survivors with worse FCR or overall health reported higher FCR. Most studies found caregivers' FCR levels were equal to or greater than survivors'. Caregivers' FCR was persistently elevated but peaked approaching survivor follow-up appointments. Caregivers' FCR was associated with poorer quality of life in caregivers and survivors. Three studies found couple-based FCR interventions were acceptable, but had limited efficacy.

CONCLUSIONS

FCR in caregivers is prevalent, persistent and burdensome. Younger caregivers of survivors with worse overall health or FCR are at the greatest risk. Further research on identifying and treating caregivers' FCR is required.

IMPLICATIONS FOR CANCER SURVIVORS

Caregiver and survivor FCR are similarly impactful and appear interrelated. Addressing FCR may improve outcomes for both cancer caregivers and survivors.

Fear about Alzheimer's disease among Israeli and German laypersons, persons with Mild Neurocognitive Disorder and their relatives: a qualitative study

OBJECTIVES

Alzheimer's disease (AD), the most common type of dementia, is one of the most feared diseases, obstructing help-seeking, and leading to discrimination. While research interest in fear of developing AD is increasing, little is known about its characterization, triggers, and consequences, especially among different cultures. In this study, we aimed at exploring and characterizing AD fear as experienced by laypersons (LP), persons with Mild Neurocognitive Disorder (MND), and their relatives, in Israel and Germany.

DESIGN

A qualitative study using focus groups (FGs) and semi-structured interviews was used. Thematic content analysis was conducted to extract key themes.

SETTING

Israeli and German not yet diagnosed people.

PARTICIPANTS

The study included a total of 130 participants (63 Israeli and 67 German participants) representing 3 groups: LP (n = 82), persons with MND (n = 28), and relatives of persons with MND (n = 20).

RESULTS

Two overarching themes were identified across groups and countries: fear of developing AD and fear of stigmatization. Other types of fear, such as fear of a person with AD, fear about the impact of a diagnosis of AD on family members, fear of becoming a caregiver, and fear of losing one's self-determination because of developing AD, were specific to a group type or country. Different types of fear were awakened by different triggers, and were dealt with different coping strategies.

Association Between Daily Worry, Pathological Worry, and Fear of Progression in Patients With Cancer

Background: Fear of progression (FoP), or fear of cancer recurrence (FCR), is characterized by worries or concerns about negative illness-related future events. Actually, to worry is a common cognitive process that, in its non-pathological form, belongs to daily life. However, worry can also become pathological appearing as a symptom of mental disorders. This study aimed at investigating the associations among daily worry, pathological worry, and FoP in patients with cancer.

Methods: This is a cross-sectional study that includes 328 hospitalized patients with cancer. Patients filled out the FoP Questionnaire (FoP-Q), the Worry Domains Questionnaire (WDQ) for the assessment of daily worry, and the Penn State Worry Questionnaire (PSWQ) for the assessment of pathological worry. Depressive, anxiety, and somatic symptoms were measured with modules of the Patient Health Questionnaire [Patient Health Questionnaire-Depressive Symptoms (PHQ-2), Generalized Anxiety Disorder-2 (GAD-2), and Patient Health Questionnaire-Somatic Symptoms (PHQ-15)]. Furthermore, a structured clinical interview was conducted for the assessment of anxiety disorders. The hierarchical multiple linear regression analysis was used to identify factors independently associated with FoP.

Results: Mean age of the participants was M = 58.5 years (SD = 12.8), and 64.6% were men. FoP and worry were significantly intercorrelated (r = 0.58–0.78). The level of FoP was most strongly associated with daily worry (β = 0.514, p < 0.001), followed by pathological worry (β = 0.221, p < 0.001). Further significant determinants were younger age and depressive and anxiety symptoms. Clinical variables were not independently associated with FoP. The final model explained 74% of the variance.

Discussion: Fear of progression is strongly associated with daily worry and pathological worry. These results bring up the question of whether FoP is an expression of a general tendency to worry. Whether a general tendency to worry, in fact, represents an independent vulnerability factor for experiencing FCR/FoP needs to be investigated in a longitudinal research design.

Factors Associated With Fear of Cancer Recurrence in Family Caregivers of Cancer Survivors: A Systematic Review

Objective: Fear of cancer recurrence (FCR) is a significant concern for family caregivers of cancer survivors and is associated with many adverse outcomes, including increased emotional distress and poorer quality of life. Although several theoretical models have been proposed to account for FCR in cancer survivors, their applicability to caregivers is unknown. The aim of this review was to identify clinical, demographic and psychological factors that are associated with, and predict, FCR in caregivers of cancer survivors.

Method: AMED, CINAHL, Medline, PsycINFO, and Scopus were systematically searched for relevant studies reporting quantitative data on factors associated with FCR or similar constructs (e.g., worry or anxiety about cancer recurrence) in family caregivers of adult cancer survivors. Included studies were assessed for methodological quality using a standardized checklist adapted from the Agency for Healthcare Research and Quality.

Results: Sixteen studies, half of which were cross-sectional, were included and summarized narratively. Non-modifiable factors, including age (n = 6) and treatment modality (n = 4), were found to be associated with increased FCR. Significant positive associations were also reported between illness perceptions and FCR (n = 3). However, there was heterogeneity across included studies with regards to factors examined and most were conducted in the USA. There were also several methodological limitations to the included studies.

Conclusions: Research examining FCR in caregivers of cancer survivors has predominantly focused on demographic and clinical factors. Given the paucity of research exploring the psychological mechanisms underpinning FCR, future research should investigate theoretical underpinnings of FCR in caregivers of cancer survivors to support the development of psychological interventions for this population.

Fear of cancer recurrence in patients undergoing germline genome sequencing

PURPOSE

Fear of cancer recurrence/occurrence (FCR/O) is prevalent and associated with poorer psychological outcomes but can also motivate individuals to pursue genomic information about cancer risk. Guided by Protection Motivation Theory, this study investigated FCR/O prevalence and associated factors among probands previously diagnosed with a cancer of likely heritable origin, and their relatives, who had agreed to have germline genome sequencing.

METHODS

Three hundred and forty-eight probands and 167 relatives completed the Concerns about Recurrence Questionnaire (adapted for occurrence for some relatives) within 1 month of agreeing to undertake genome sequencing. Linear regressions investigated demographic, disease, attitude and behavioral associations with FCR/O.

RESULTS

Probands demonstrated greater FCR compared to relatives. In probands, greater FCR was associated with being female, non-English speaking at home, less time since diagnosis, greater intention to change behavior if gene variant found, lower perceived ability to cope with results, higher perceived susceptibility to having a recurrence, and more negative attitudes towards uncertainty. For relatives with cancer, greater FCR was associated with being male, greater intention to change behavior if a gene variant found, and higher perceived susceptibility to recurrence. In relatives without cancer, greater FCO was associated with not having had genetic testing prior to this study, lower perceived ability to cope with results, and higher perceived susceptibility to developing cancer.

CONCLUSION

Current findings on FCR/O prevalence and associated demographic and attitudinal variables in those who pursue genomic risk information might be used to target interventions that can prevent adverse psychological outcomes in vulnerable patients.

A Systematic Review of Fear of Cancer Recurrence Among Indigenous and Minority Peoples

While cancer survivors commonly experience fear and anxiety, a substantial minority experience an enduring and debilitating fear that their cancer will return; a condition commonly referred to as fear of cancer recurrence (FCR). Despite recent advances in this area, little is known about FCR among people from Indigenous or other ethnic and racial minority populations. Given the high prevalence and poor outcomes of cancer among people from these populations, a robust understanding of FCR among people from these groups is critical. The current review identified and aggregated existing literature on FCR amongst adult cancer survivors from Indigenous and minority populations. The protocol of this review was registered with PROSPERO in July 2020 (Registration number: CRD42020161655). A systematic search of bibliographic databases was conducted for relevant articles published from 1997 to November 2019. Data from eligible articles were extracted and appraised for quality by two independent reviewers. Nineteen articles from four countries (United States of America, Canada, Australia and the United Kingdom) met the inclusion criteria, including 14 quantitative, 4 qualitative and 1 mixed-methods study. Only one article reported on an Indigenous population. Few studies reported on FCR prevalence (n = 3) or severity (n = 9). While the variation in tools used to measure FCR hindered a robust estimate of severity, results suggested some differences in FCR severity between minority and dominant populations, although these may have been due to study metholodological differences. Few factors were reported as being associated with FCR in minorities across multiple studies. The qualitative synthesis found five themes associated with the lived experience of FCR: (i) variations in the lived experience of FCR; (ii) spirituality and worldview impacting on FCR; (iii) the importance of staying positive; (iv) complexities around support; and (v) increasing cancer knowledge. The findings of this review highlight differences in FCR across cultures and contexts, which reinforces the need for culturally-specific approaches to this condition. The dearth of research in this area is of concern given the significant burden of cancer in these populations. A deeper understanding of this condition among Indigenous and minority populations is critical to developing and delivering appropriate and effective psychosocial care for cancer survivors from these groups.

Fear of Cancer Recurrence, Health Anxiety, Worry, and Uncertainty: A Scoping Review About Their Conceptualization and Measurement Within Breast Cancer Survivorship Research

Objective: Fear of Cancer Recurrence (FCR), Health Anxiety (HA), worry, and uncertainty in illness are psychological concerns commonly faced by cancer patients. In survivorship research, these similar, yet different constructs are frequently used interchangeably and multiple instruments are used in to measure them. The lack of clear and consistent conceptualization and measurement can lead to diverse or contradictory interpretations. The purpose of this scoping review was to review, compare, and analyze the current conceptualization and measurements used for FCR, HA, worry, and uncertainty in the breast cancer survivorship literature to improve research and practice. Inclusion Criteria: We considered quantitative, qualitative, and mixed methods studies of breast cancer survivors that examined FCR, HA, worry, or uncertainty in illness as a main topic and included a definition or assessment of the constructs. Methods and Analysis: The six-staged framework was used to guide the scoping review process. Searches of PubMed, CINAHL, and PsycINFO databases were conducted. The principle-based qualitative analysis and simultaneous content analysis procedures were employed to synthesize and map the findings. Findings: After duplicate removal, the search revealed 3,299 articles, of which 82 studies met the inclusion criteria. Several critical attributes overlapped the four constructs, for example, all were triggered by internal somatic and external cues. However, several unique attributes were found (e.g., a sense of loss of security in the body is observed only among survivors experiencing FCR). Overall, findings showed that FCR and uncertainty in illness are more likely to be triggered by cancer-specific factors, while worry and HA have more trait-like in terms of characteristics, theoretical features, and correlates. We found that the measures used to assess each construct were on par with their intended constructs. Eighteen approaches were used to measure FCR, 15 for HA, 8 for worry, and 4 for uncertainty. Conclusion: While consensus on the conceptualization and measurement of the four constructs has not yet been reached, this scoping review identifies key similarities and differences to aid in their selection and measurement. Considering the observed overlap between the four studied constructs, further research delineating the unique attributes for each construct is warranted.

Pursuing germline genome sequencing to reduce illness uncertainty may involve additional uncertainties for cancer patients: A mixed-methods study

Cancer-related illness uncertainty has been associated with poorer psychological outcomes for patients. While some cancer patients believe obtaining genomic information will reduce their illness uncertainty, the complexity of genomics has the potential to compound illness uncertainty. The aim of this mixed-methods study was to investigate uncertainty in patients with a cancer of likely heritable origin immediately following their decision to have germline genome sequencing. Participant (N = 348) negative attitudes toward uncertainty were associated with higher satisfaction with decision to have germline genome sequencing and greater fear of cancer recurrence. Thematic analysis of semi-structured interviews with a subset of participant (N = 20) revealed the following four themes: (a) germline genome sequencing to reduce illness uncertainty; (b) germline genome sequencing to reduce uncertainty related to relatives' risk; (c) uncertainty generated by germline genome sequencing; and (d) resilience and coping with uncertainty. This study demonstrated the complexity of uncertainty in germline genome sequencing in cancer patients. These results provide genomic healthcare professionals with important information about cancer patient's motivation to pursue germline genome sequencing, the specific uncertainties generated by germline genome sequencing, and how cancer patients cope with uncertainty.

Factor structure of the Fear of Cancer Recurrence Inventory (FCRI): Comparison of international FCRI factor structure data and factor analysis of the Dutch FCRI-NL using three predominantly breast cancer samples

Objective

Factor structure results of Fear of Cancer Recurrence Inventory (FCRI) translations are inconclusive. Through investigating the factor structure, this study aimed to improve the FCRI and its usability. Therefore, we did a comprehensive comparison of the factor structure results of all translations, by exploring and improving the structure of the Dutch FCRI‐NL and by testing this new factor structure in two patient samples.

Methods

To compare factor structure results of FCRI translations, we did a literature search using PubMed and Google Scholar. We performed exploratory factor analysis (EFA) in a mixed cancer sample. The confirmatory factor analyses (CFAs) were secondary analyses performed in two randomized controlled trial samples: consecutive breast cancer patients and distressed, mainly breast cancer patients.

Results

All translations showed comparable and reasonable factor structure results; however, the FCRI factor structure can be improved. The EFA resulted in a four‐factor solution: fear of cancer recurrence (FCR) severity, cognitive coping, impact of FCR on functioning and behavioural coping. However, the 4‐factor CFAs did not fit the sample 2 and 3 data well.

Conclusion

Further exploring the FCRI‐NL factor structure did not result in a psychometrically stronger FCRI‐NL. Therefore, we recommend retaining the 7‐factor FCRI‐NL.

Fear of Cancer Recurrence and Inhibited Disclosure: Testing the Social-Cognitive Processing Model in Couples Coping With Breast Cancer

BACKGROUND

Withholding cancer-related concerns from one's partner (protective buffering) and feeling that one's partner is inaccessible or unresponsive to such disclosure (social constraints) are two interpersonal interaction patterns that separately have been linked to poorer adjustment to cancer.

PURPOSE

Guided by the Social-Cognitive Processing Model, we examined the joint effects of social constraints and protective buffering on fear of cancer recurrence (FCR) in survivors and spouses. Social constraints and protective buffering were hypothesized to emerge as independent predictors of higher FCR.

METHODS

Early-stage breast cancer survivors and spouses (N = 79 couples; 158 paired individuals) completed up to five repeated measures of FCR, social constraints, protective buffering, and relationship quality during the year postdiagnosis. A second-order growth curve model was estimated and extended to test the time-varying, within-person effects of social constraints and protective buffering on a latent FCR variable, controlling for relationship quality.

RESULTS

As hypothesized, greater social constraints and protective buffering significantly (p < .05) predicted higher concurrent FCR at the within-person level, controlling for global relationship quality and change in FCR over time. The fixed effects were found to be similar for both survivors and spouses.

CONCLUSIONS

Findings suggest that interaction patterns resulting in inhibited disclosure are associated with greater FCR for both survivors and spouses, consistent with the Social-Cognitive Processing Model. This work adds to the growing body of research highlighting the social context of FCR.

Setting an International Research Agenda for Fear of Cancer Recurrence: An Online Delphi Consensus Study

Background

Fear of cancer recurrence (FCR) is common amongst cancer survivors. There is rapidly growing research interest in FCR but a need to prioritize research to address the most pressing clinical issues and reduce duplication and fragmentation of effort. This study aimed to establish international consensus among clinical and academic FCR experts regarding priorities for FCR research.

Methods

Members of the International Psycho-oncology Society (IPOS) Fear of Cancer Recurrence Special Interest Group (FORwards) were invited to participate in an online Delphi study. Research domains identified in Round 1 were presented and discussed at a focus group (Round 2) to consolidate the domains and items prior to presentation in further survey rounds (Round 3) aimed at gaining consensus on research priorities of international significance.

Results

Thirty four research items were identified in Round 1 and 33 of the items were consolidated into six overarching themes through a focus group discussion with FCR experts. The 33 research items were presented in subsequent rounds of the delphi technique. Twenty one participants contributed to delphi round 1, 16 in round 2, and 25 and 29 participants for subsequent delphi rounds. Consensus was reached for 27 items in round 3.1. A further four research items were identified by panelists and included in round 3.2. After round 3.2, 35 individual research items were ratified by the panelists. Given the high levels of consensus and stability between rounds, no further rounds were conducted. Overall intervention research was considered the most important focus for FCR research. Panelists identified models of care that facilitate greater access to FCR treatment and evaluation of the effectiveness of FCR interventions in real world settings as the two research items of highest priority. Defining the mechanisms of action and active components across FCR/P interventions was the third highest priority identified.

Conclusion

The findings of this study outline a research agenda for international FCR research. Intervention research to identify models of care that increase access to treatment are based on a flexible approach based on symptom severity and can be delivered within routine clinical care were identified as research areas to prioritize. Greater understanding of the active components and mechanisms of action of existing FCR interventions will facilitate increased tailoring of interventions to meet patient need.

Cause or Effect? The Role of Prognostic Uncertainty in the Fear of Cancer Recurrence

Background

Fear of cancer recurrence (FCR) is an important cause of suffering for cancer survivors, and both empirical evidence and theoretical models suggest that prognostic uncertainty plays a causal role in its development. However, the relationship between prognostic uncertainty and FCR is incompletely understood.

Objective

To explore the relationship between prognostic uncertainty and FCR among patients with ovarian cancer (OC).

Design

A qualitative study was conducted utilizing individual in-depth interviews with a convenience sample of patients with epithelial ovarian cancer who had completed first-line treatment with surgery and/or chemotherapy. Semi-structured interviews explored participants’ (1) understanding of their prognosis; (2) experiences, preferences, and attitudes regarding prognostic information; and (3) strategies for coping with prognostic uncertainty. Inductive qualitative analysis and line-by-line software-assisted coding of interview transcripts was conducted to identify key themes and generate theoretical insights on the relationship between prognostic uncertainty and FCR.

Results

The study sample consisted of 21 participants, nearly all of whom reported experiencing significant FCR, which they traced to an awareness of the possibility of a bad outcome. Some participants valued and pursued prognostic information as a means of coping with this awareness, suggesting that prognostic uncertainty causes FCR. However, most participants acknowledged fundamental limits to both the certainty and value of prognostic information, and engaged in various strategies aimed not at reducing but constructing and maintaining prognostic uncertainty as a means of sustaining hope in the possibility of a good outcome. Participants’ comments suggested that prognostic uncertainty, fear, and hope are connected by complex, bi-directional causal pathways mediated by processes that allow patients to cope with, construct, and maintain their uncertainty. A provisional dual-process theoretical model was developed to capture these pathways.

Conclusion

Among patients with OC, prognostic uncertainty is both a cause and an effect of FCR—a fear-inducing stimulus and a hope-sustaining response constructed and maintained through various strategies. More work is needed to elucidate the relationships between prognostic uncertainty, fear, and hope, to validate and refine our theoretical model, and to develop interventions to help patients with OC and other serious illnesses to achieve an optimal balance between these states.

Spotlight on the Fear of Cancer Recurrence Inventory (FCRI)

Fear of cancer recurrence (FCR) is a pervasive concern for people living with cancer. The rapidly expanding FCR literature has been weakened somewhat by use of miscellaneous FCR measures of varying quality. The Fear of Cancer Recurrence Inventory (FCRI) has been widely used in observational and intervention studies and the FCRI severity subscale, also known as the FCRI-Short Form (FCRI-SF), is often used to identify potential cases of clinically significant FCR. Given the FCRI's increasing use in research and clinical practice, we aimed to provide an overview, critique, and suggested improvements of the FCRI. Studies citing the original FCRI validation paper were identified and synthesised using narrative and meta-analytic methods. The 42-item FCRI has demonstrated a reasonably robust 7-factor structure across evaluations in multiple languages, although certain subscales (eg, Coping) demonstrate sub-optimal reliability. Confirmation of the cross-cultural equivalence of several FCRI translations is needed. Meta-analysis of FCRI-SF scores revealed a combined weighted mean score of 15.7/36, a little above the lowest proposed cut-off score (≥13) for clinical FCR. Depending on the FCRI-SF cut-off used, between 30.0% and 53.9% of the cancer population (ie, patients and survivors) appear to experience sub-clinical or clinical FCR. Higher FCRI scores were associated with younger age and female gender, pain/physical symptoms and psychological morbidity, consistent with the FCR literature generally. Issues regarding the application and interpretation of the FCRI remain. Whether the FCRI is well suited to assessing fear of progression as well as recurrence is unclear, the meaningfulness of the FCRI total score is debatable, and the use of the FCRI-SF to screen for clinical FCR is problematic, as items do not reflect established characteristics of clinical FCR. Refinement of the FCRI is needed for it to remain a key FCR assessment tool in future research and clinical practice.

Psychological distress and quality of life following positive fecal occult blood testing in colorectal cancer screening

OBJECTIVE

This study aimed to assess psychological functioning, quality of life, and regret about screening after a positive fecal immunochemical test (FIT) and subsequent colonoscopy, and to evaluate changes over time.

METHODS

This is a prospective cohort study. Individuals aged 55 to 75 with a positive FIT that were referred for colonoscopy between July 2017 and November 2018, were invited to complete questionnaires related to psychological distress and health-related quality of life at three predefined time points: before colonoscopy, after histopathology result notification, and after 6 months. Four questionnaires were used: the Psychological Consequences Questionnaire (PCQ), the six-item Cancer Worry Scale (CWS), the Decision Regret Scale (DRS), and the 36-item Short-Form (SF-36).

RESULTS

A total of 1066 participants out of 2151 eligible individuals were included. Patients with cancer showed a significant increase in psychological dysfunction (P = .01) and cancer worry (P = .008) after colonoscopy result notification, and a decline to pre-colonoscopy measurements after 6 months. In the no-cancer groups, psychological dysfunction and cancer worry significantly decreased over time (P < .05) but there was no ongoing decline. After 6 months, 17% of participants with no cancer experienced high level of cancer worry (CWS ≥ 10). Yet, only 5% reported high level of regret about screening participation (DRS > 25). A good global quality of life was reported in participants with no cancer.

CONCLUSION

Some psychological distress remains up to 6 months after colonoscopy in participants who tested false-positive in the Dutch bowel cancer screening program.

Study protocol: a randomized controlled trial comparing the efficacy of therapist guided internet-delivered cognitive therapy (TG-iConquerFear) with augmented treatment as usual in reducing fear of cancer recurrence in Danish colorectal cancer survivors

BACKGROUND

Cognitive therapy has been shown to reduce fear of cancer recurrence (FCR), mainly in breast cancer survivors. The accessibility of cognitive behavioural interventions could be further improved by Internet delivery, but self-guided interventions have shown limited efficacy. The aim of this study is to test the efficacy of a therapist guided internet-delivered intervention (TG-iConquerFear) vs. augmented treatment as usual (aTAU) in Danish colorectal cancer survivors.

METHODS/DESIGN

A population-based randomized controlled trial (RCT) comparing TG-iConquerFear with aTAU (1:1) in n = 246 colorectal cancer survivors who suffer from clinically significant FCR (Fear of Cancer Recurrence Inventory Short Form (FCRI-SF) ≥ 22 and semi-structured interview). Evaluation will be conducted at 2 weeks, 3 and 6 months post-treatment and between-group differences will be evaluated. Long-term effects will be evaluated after one year. Primary outcome will be post-treatment FCR (FCRI-SF). Secondary outcomes are global overall health and global quality of life (Visual Analogue Scales 0-100), bodily distress syndrome (BDS checklist), health anxiety (Whiteley-6), anxiety (SCL4-anx), depression (SCL6-dep) and sickness absence and health expenditure (register data). Explanatory outcomes include: Uncertainty in illness (Mishels uncertainty of illness scale, short form, MUIS), metacognitions (MCQ-30 negative beliefs about worry subscale), and perceived risk of cancer recurrence (Visual analogue Scale 1-100).

DISCUSSION

This RCT will provide valuable information on the clinical and cost-effectiveness of TG-iConquerFear vs. aTAU for CRC survivors with clinical FCR, as well as explanatory variables that may act as outcome moderators or mediators.

Fear of cancer recurrence promotes cancer screening behaviors among family caregivers of cancer survivors

BACKGROUND

Fear of cancer recurrence (FCR) has been associated with cancer screening behaviors among cancer survivors, but to the authors' knowledge, the question of whether the same is true for caregivers is unknown. The current study investigated the extent to which FCR among caregivers predicted their cancer screening behaviors years after their relatives' cancer diagnosis.

METHODS

A total of 813 caregivers (67% of whom were female, mean age of 56 years, and 92% non-Hispanic white) completed surveys 2 years (T1) and 8 years (T2) after their patients' cancer diagnosis. FCR, anxiety (Profile of Mood States-Short Form [POMS-SF]), and general mental health (Medical Outcomes Study 36-Item Short-Form Health Survey [MOS SF-36]) were reported at T1; caregivers' engagement in screening for colorectal, breast, and prostate cancers because of the patients' diagnoses were reported at T2.

RESULTS

Caregivers were found to engage in cancer screening at rates similar to those of the national average. Controlling for covariates, hierarchical logistic regression modeling for each type of cancer screening demonstrated that greater FCR was linearly related to a higher likelihood of undergoing colorectal cancer screening (odds ratio [OR], 1.15) and maintaining prostate cancer screening (OR, 1.34), but a lower likelihood of maintaining breast cancer screening in an age-appropriate manner (OR, 0.27). Examining curvilinear effects demonstrated that moderate levels of FCR were associated with a higher likelihood of maintaining age-appropriate colorectal cancer screening (OR, 1.48).

CONCLUSIONS

The overall FCR among caregivers uniquely promotes their engagement in cancer screening behaviors. The role of caregivers' FCR in other types of cancer preventive behaviors and ways to channel FCR concerns into promoting healthy lifestyle behaviors should be investigated.

Testing a model of fear of cancer recurrence or progression: the central role of intrusions, death anxiety and threat appraisal

We recently proposed a model of cancer-related anxiety to account for the etiology and maintenance of clinically significant anxiety in the context of cancer. This study tested predictions arising from the model to explain fear of cancer recurrence or progression (FCR). Patients with cancer were recruited from a research registry or outpatient hospital clinics (n = 211). In bivariate analyses, FCR was associated with metacognitive beliefs, intolerance of uncertainty, core belief disruption, less meaning in life, social constraints, death anxiety, intrusions, threat appraisal, and coping. A hierarchical regression explained 65% of the variance in FCR. FCR was predicted by younger age, intrusions, death anxiety, threat appraisal and meta-cognitions. The findings highlight the importance of both cognitive processes and content in FCR, including intrusions, fears about death and dying, beliefs about worry, and threat appraisals.

Perceived cancer-related pain and fatigue, information needs, and fear of cancer recurrence among adult survivors of childhood cancer

OBJECTIVE

Pain and fatigue are under-researched late effects of childhood cancer and its treatment, and may be interpreted by survivors as indicating cancer recurrence. Moreover, unmet information needs for managing pain and fatigue may be related to fear of cancer recurrence. We investigated the complex relationships between perceived cancer-related pain and fatigue, unmet information needs for managing pain and fatigue, and fear of cancer recurrence.

METHODS

We surveyed 404 adult survivors of any form of childhood cancer (M = 16.82 years since treatment completion).

RESULTS

Many survivors reported perceived cancer-related pain (28.7%) and fatigue (40.3%), and anticipated future pain (19.3%) and fatigue (26.2%). These symptomologies were all related to unmet information needs for managing pain (18.8%) and fatigue (32.2%; all p's<.001). Survivors reporting unmet information needs for managing pain (B = .48, 95% CI = 0.19-0.76, p = .001) and fatigue (B = .32, 95% CI = 0.06-0.52, p = .015) reported higher fear of cancer recurrence than survivors reporting no information needs.

CONCLUSION

Survivors often have unmet information needs for managing pain and fatigue, and these unmet needs are related to fear of cancer recurrence.

PRACTICE IMPLICATIONS

Long-term follow-up clinics should assess pain and fatigue. Information provision about pain and fatigue may be an important tool to help manage fear of cancer recurrence.

The role of daily couple communication in the relationship between illness representation and fear of cancer recurrence in breast cancer survivors and their spouses

OBJECTIVE

Previous studies have shown the significance of illness representation in maintaining of fear of cancer recurrence (FCR). The current study explored the association of illness representation and fear of cancer recurrence in daily life among breast cancer survivors and their spouses, considering the role of daily couple communication.

METHODS

A total of 54 couples in which the wives were breast cancer survivors were recruited to complete Brief Illness Perception Questionnaire and to report their communication information and fear of cancer recurrence in daily life.

RESULTS

At the between-person level, individuals with severer illness representation were likely to express more negative and less positive information in daily life, irrespective of whether they were patients or spouses. At the within-person level, perceptions of positive information acted as a mediator between disclosures of positive/negative information and changes in FCR.

CONCLUSIONS

There were interactions of the relationship of illness representation to FCR between breast cancer survivors and their spouses. Daily couple communication played critical roles in the association between illness representation and FCR.
