Fear of cancer recurrence and mental health: A comprehensive meta-analysis

Fear of cancer recurrence among adolescent and young adult cancer survivors: a mixed-methods systematic review

PURPOSE

Fear of cancer recurrence (FCR) is common and burdensome in adolescent and young adult (AYA) cancer survivors. This systematic review examines FCR assessment, prevalence, severity, progression, related factors, consequences, and interventions in AYA cancer survivors.

METHODS

Electronic databases including PubMed, CINAHL, PsycINFO, Cochrane, and Embase were searched from their inception to October 2024. Two reviewers identified eligible peer-reviewed empirical studies, including both qualitative and quantitative ones on FCR in AYA survivors. The risk of bias was assessed using the Mixed-Methods Appraisal Tool. Quantitative studies were synthesized narratively, while qualitative studies underwent thematic synthesis.

RESULTS

Among the 5340 studies identified, 34 studies were included finally. 21.4 to 93.3% of AYA cancer survivors experienced FCR. About one-third of survivors with moderate or high FCR improved over time. Female survivors, those with advanced cancer stages, and individuals with negative illness perceptions or higher anxiety reported higher FCR. Persistent FCR was associated with increased psychological problems and lower quality of life. Two studies on behavioral interventions, particularly internet-based cognitive-behavioral therapy (CBT), were acceptable but had limited evidence of efficacy.

CONCLUSION

FCR is prevalent among AYA cancer survivors, particularly in female survivors, those with advanced cancer stages, and those with negative perceptions or higher anxiety. A significant proportion experience persistent, but variability in current evidence limits a comprehensive understanding of its severity, progression, and intervention efficacy. To enhance FCR management, the use of validated assessment tools is essential in both research and clinical contexts. Addressing the physical and psychological aspects of survivorship through comprehensive care is crucial for alleviating FCR and improving overall well-being.

IMPLICATIONS FOR CANCER SURVIVORS

Identifying the key factors of FCR will stimulate the research and the development of targeted interventions for AYA cancer survivors.

The Relational Experience of Fear of Cancer Recurrence in Family Caregivers: A Reflexive Thematic Analysis Study

Fear of cancer recurrence (FCR) affects approximately 50% of family caregivers. While FCR in cancer patients has been well-documented, less is known about the experience of FCR in family caregivers. This study aimed to qualitatively explore the distinct characteristics of FCR in family caregivers. A focus group and semi-structured interviews were conducted via videoconferencing with family caregivers of cancer survivors (stages I-III, finished treatment, no recurrence). Participants were recruited through Canadian hospitals, community partners, and social media. The focus group and qualitative interviews explored family caregivers' experiences of FCR, including its content, frequency, impact, and management. A reflexive thematic analysis was used. In total, twenty family caregivers participated. Six participated in the focus group. Sixteen participated in the interviews. Two participated in both. Family caregivers described their experience of FCR as all-consuming, constant, and marked by a sense of helplessness. Qualitative analysis revealed a major theme of relational aspects of FCR in family caregivers, with the following four inter-related themes: patient-centric hypervigilance, self-silencing, FCR as isolating, and finding support. This qualitative study examined the experiences of family caregivers living with FCR. Our findings highlight that relational factors shape how family caregivers experience and manage their FCR. High-quality survivorship care should be redefined to include FCR interventions tailored to family caregivers.

Association between fear of cancer recurrence and emotional distress in breast cancer: a latent profile and moderation analysis

BACKGROUND

Breast cancer patients often experience significant psychological challenges, particularly fear of cancer recurrence (FCR), which is a prevalent and distressing concern following diagnosis. FCR can lead to heightened emotional distress, including anxiety and depression. Resilience, the ability to adapt positively to adversity, may play a crucial role in mitigating these negative emotional outcomes. This study aims to explore the heterogeneity of FCR among breast cancer patients and examine the moderating effect of resilience on the relationship between FCR and emotional distress.

MATERIALS AND METHODS

A cohort of 398 breast cancer patients participated in the Be Resilient to Breast Cancer (BRBC) program between May and December 2023. Surveys were administered to assess FCR, resilience, and emotional distress levels. Data were analyzed using two approaches: latent profile analysis (LPA) to identify distinct FCR profiles and moderation analysis to evaluate the role of resilience.

RESULTS

Three distinct FCR profiles were identified: low (27.5%), middle (53%), and high (19.5%). Resilience significantly moderated the association between FCR and anxiety (B = 0.115, SE = 0.046, P = 0.014), but no significant moderating effect was observed for depression.

DISCUSSION

The findings highlight significant heterogeneity in FCR among breast cancer patients, with a substantial proportion experiencing moderate to high levels of FCR. Resilience was found to buffer the impact of FCR on anxiety, suggesting that interventions aimed at enhancing resilience could alleviate anxiety related to FCR in this population. These results underscore the importance of incorporating resilience-focused strategies into psychological therapies for breast cancer patients.

Exploring Healthcare Provider Experiences with the EXCEL Exercise Referral Pathway for Individuals Living with and Beyond Cancer

Exercise is an evidence-based strategy shown to reduce the negative side effects associated with cancer treatment for individuals living with and beyond cancer (LWBC). Healthcare providers (HCPs) play a critical role in promoting exercise for these individuals. Notwithstanding, several barriers hinder HCPs' ability to discuss and support exercise in clinical practice. EXCEL is an exercise intervention designed to address health disparities in access to exercise oncology resources for rural/remote individuals LWBC, including a referral pathway for HCPs to use. The purpose of this study was to evaluate HCP experiences using the EXCEL exercise referral pathway. We employed an interpretive description methodology, using semi-structured interviews to assess HCP experiences with EXCEL. Overall, HCPs felt empowered to refer to exercise when they were supported in doing so. The findings highlighted (1) a need for a better understanding of the role of exercise professionals and their integration into cancer care; (2) the need for efficient referral systems including embedding referrals into existing health care electronic record systems; and (3) sharing patient feedback with exercise oncology programs back to the HCPs to drive continued referrals.

Conflicting health information increases fear of disease progression in HPV-infected individuals: disease uncertainty as mediator and tolerance of uncertainty as buffer

Background

Human papillomavirus (HPV) infection is highly prevalent, and infected individuals frequently encounter HPV-specific conflicting health information about their condition. Although this phenomenon is well documented, the mechanisms by which such information influences fear of progression (FoP) and potential interventions remain unexplored.

Methods

This research was conducted in two phases. Phase 1 (n = 218) developed and validated the HPV-Specific Conflicting Health Information Scale. Phase 2 (n = 501) examined disease uncertainty as a mediator and tolerance of uncertainty as a moderator among HPV-positive female patients.

Results

The HPV-Specific Conflicting Health Information Scale demonstrated a two-dimensional structure representing objective experiences and subjective perceptions of HPV-specific conflicting health information. Phase 2 revealed that HPV-specific conflicting health information indirectly influenced Fear of Progression via disease uncertainty, with this relationship moderated by individuals' tolerance of uncertainty.

Conclusion

This study established the first validated measure of HPV-specific conflicting health information. The findings indicate that enhancing tolerance of uncertainty may serve as an effective complement to reducing conflicting information exposure in addressing HPV-related psychological distress.

Health anxiety in cancer patients, assessed with the Whiteley Index

OBJECTIVE

Health anxiety (HA) is frequently observed in patients suffering from a severe disease such as cancer. This study aimed to test the psychometric properties of the Whiteley Index-7 (WI-7) measuring HA and to identify prognostic factors for heightened HA in cancer patients.

METHODS

A sample of 1723 cancer patients, treated in a German rehabilitation clinic, completed the Whiteley Index-7, the Generalized Anxiety Disorder screener GAD-7, the Patient Health Questionnaire PHQ-9, the Fear of Progression questionnaire FoP-Q-12, the Concerns About Cancer Recurrence questionnaire CARQ-4, and two subscales of the EORTC QLQ-SURV100.

RESULTS

The internal consistency of the WI-7 was good (Cronbach's α = 0.85), and the correlations between the WI-7 and other scales were as follows: 0.64 (GAD-7), 0.63 (PHQ-9), 0.75 (FoP-Q-12), 0.71 (CARQ-4), 0.66 (SURV-HD), and 0.75 (SURV-NHO). Women showed markedly higher levels of HA than men (effect size: d = 0.40), and patients aged 60 years and above reported lower levels of HA than younger patients (d = -0.32). Melanoma patients showed the highest HA mean score (M = 10.9), and patients receiving antibody therapy showed heightened levels of HA (M = 10.7). When considering age and sex, the effects of tumor type and treatment become smaller than in the univariate analyses.

CONCLUSION

The WI-7 is a suitable instrument for assessing HA in cancer patients. When evaluating the effects of cancer type or treatment on HA, one has to take into account the age and sex distribution. Younger patients and women deserve special attention regarding HA.

Social support, fear of cancer recurrence and sleep quality in breast cancer: A moderated network analysis

PURPOSE

Fear of cancer recurrence (FCR) contributes to sleep problems and social support is a buffering factor in the literature. However, the moderating effect of social support between FCR and sleep quality is unclear.

METHODS

The moderating role of social support was examined in a cohort of 460 breast cancer patients from the 2024 Be Resilient to Breast Cancer (BRBC) program from a microscopic perspective using moderated network analysis, and then assessed macroscopically by Johnson-Neyman and response surface analysis. The Fear of Progression Questionnaire-Short Form, Perceived Social Support Scale and Pittsburgh Sleep Quality Index scale were employed in this study.

RESULTS

Social support significantly moderated the relationship between general anxiety and sleep efficiency. General anxiety was positively correlated with sleep efficiency at high levels of social support (t = 3.774, P < 0.001). Patients with high social support and low FCR experienced better sleep (F = 6.166, P < 0.01).

CONCLUSION

Our study deepens the understanding of the association between FCR, social support, and sleep quality, and emphasizes social support as a positive strategy for cancer patients to improve their physical and mental health.

Fear of cancer recurrence experienced by pediatric survivors of childhood cancer: a scoping review

PURPOSE

In contrast to the extensive literature on fear of cancer recurrence (FCR) experienced by adults, literature evaluating pediatric FCR has just begun to emerge. Given the rapidly expanding body of work assessing FCR in childhood and adolescence, a scoping review was conducted to synthesize existing findings. We aimed to assess (1) the characteristics and methods of this literature, (2) how pediatric FCR has been measured, and (3) the extant knowledge of FCR experienced by pediatric survivors of cancer.

METHODS

Inclusion criteria were: (1) original reports, (2) participants diagnosed with cancer before age 18, (3) current mean age under 18, (4) FCR was explicitly measured (quantitatively) or captured (qualitatively) via survivor self-report, and (6) published in English. Exclusion criteria were: (1) case studies, and (2) grey literature. Three databases (Embase, MEDLINE, PsycINFO) and reference lists from included studies were searched. All studies were screened for inclusion by two authors and all data were extracted by a single author.

RESULTS

Of 3906 identified studies, 19 were included. Studies (published 1991 - 2023) encompassed diverse geographical locations, study designs, and measurement methods. Few assessed FCR as a primary aim (n = 6, 32%). FCR was experienced by 43 - 90% of pediatric survivors. FCR was often positively associated with somatic symptoms and negatively associated with quality of life and emotional functioning.

CONCLUSION

FCR is a prevalent issue for children and adolescents. Additional evidence is needed to explore and confirm preliminary findings. Future pediatric FCR studies should aim to align with published priority research areas.

The Ottawa clinical fear of recurrence instruments: A screener, self-report, and clinical interview

OBJECTIVE

Clinical fear of cancer recurrence (FCR) was recently defined by a group of experts during a Delphi study. Five criteria were agreed upon, namely: (a) high levels of preoccupation, (b) high levels of worry, (c) that are persistent, (d) hypervigilance and hypersensitivity to physical sensations that e) may result in functional impairment. No existing instruments comprehensively capture all these criteria for clinical FCR.

METHODS

To remedy this gap, a set of three patient-reported outcome instruments including a one-item screener, self-report questionnaire, and semi-structured clinical interview, named the Ottawa Clinical Fear of Recurrence instruments, were developed. To do so, the research team first conducted a literature review of potential items. Additional FCR experts discussed the content of the screener and interview. The self-report's items were assessed for content validity by the same expert panel using Likert ratings and the Content Validity Index to narrow down the number of items. The three instruments were piloted with a group of cancer survivors to assess face validity following the European Organization for Research and Treatment of Cancer recommendations.

RESULTS

The literature review and content validity assessment led to a final draft pre-pilot of 23 potential items for the self-report questionnaire. The instruments were piloted. Pilot study participants suggested changing wording and response options (particularly for the self-report) for greater clarity.

CONCLUSIONS

Based on the feedback received, minor modifications were made, mostly for the self-report. In general, content and face validity for the three instruments were good for both experts and cancer survivors.

Application of artificial intelligence in the diagnosis, treatment, and recurrence prediction of peritoneal carcinomatosis

Peritoneal carcinomatosis (PC) is a type of secondary cancer which is not sensitive to conventional intravenous chemotherapy. Treatment strategies for PC are usually palliative rather than curative. Recently, artificial intelligence (AI) has been widely used in the medical field, making the early diagnosis, individualized treatment, and accurate prognostic evaluation of various cancers, including mediastinal malignancies, colorectal cancer, lung cancer more feasible. As a branch of computer science, AI specializes in image recognition, speech recognition, automatic large-scale data extraction and output. AI technologies have also made breakthrough progress in the field of peritoneal carcinomatosis (PC) based on its powerful learning capacity and efficient computational power. AI has been successfully applied in various approaches in PC diagnosis, including imaging, blood tests, proteomics, and pathological diagnosis. Due to the automatic extraction function of the convolutional neural network and the learning model based on machine learning algorithms, AI-assisted diagnosis types are associated with a higher accuracy rate compared to conventional diagnosis methods. In addition, AI is also used in the treatment of peritoneal cancer, including surgical resection, intraperitoneal chemotherapy, systemic chemotherapy, which significantly improves the survival of patients with PC. In particular, the recurrence prediction and emotion evaluation of PC patients are also combined with AI technology, further improving the quality of life of patients. Here we have comprehensively reviewed and summarized the latest developments in the application of AI in PC, helping oncologists to comprehensively diagnose PC and provide more precise treatment strategies for patients with PC.

Group-based trajectory modeling for fear of cancer recurrence in cancer survivors: a systematic review

PURPOSE

We aimed to systematically review studies that used a group-based trajectory modeling approach to explore the categories of fear of cancer recurrence (FCR) trajectories and their predictors in cancer survivors.

METHODS

MEDLINE, EMBASE, CINAHL, Scopus, and Web of Science were searched. Three authors independently reviewed the literature for predefined eligibility criteria. The Joanna Briggs Institute critical appraisal tools for Cohort Studies and the Guidelines for Reporting on Latent Trajectory Studies were used to assess the quality of included studies. A qualitative synthesis of the included studies was performed.

RESULTS

Ninety-eight studies were retrieved after removing duplicates, and 11 studies met the criteria for inclusion. There are four types of FCR trajectories: stable, decreasing, increasing, and stable-then-decreasing-then-increasing. The following factors were considered significant predictors of FCR trajectory category in at least one of the included studies: age, race, income, education, employment, cancer stage, physical symptoms, depression, anxiety, satisfaction with medical care, and selected cognitive and behavioral factors.

CONCLUSIONS

There was considerable heterogeneity among the studies included in study design and FCR trajectory results. Factors that significantly predicted FCR trajectory categories mostly focused on psychological characteristics. The correlation of sociodemographic and disease-related predictors with FCR trajectory categories was not consistent among the included studies.

IMPLICATIONS FOR CANCER SURVIVORS

We suggest that future scholars should incorporate more psychological factors when identifying cancer survivors who persistently maintain a high level of FCR and developing FCR mitigation measures.

Fear of Cancer Progression: A Comparison between the Fear of Progression Questionnaire (FoP-Q-12) and the Concerns about Recurrence Questionnaire (CARQ-4)

As cancer patients often suffer from fear of cancer progression (FoP), valid screening for FoP is of high relevance. The aims of this study were to test psychometric properties of two FoP questionnaires, to determine their relationship to other anxiety-related constructs, and to analyze the impact of sociodemographic and clinical factors on the FoP. Our sample consisted of n = 1733 patients with mixed cancer diagnoses. For measuring FoP, the Fear of Progression questionnaire (FoP-Q-12) and the Concerns About Cancer Recurrence Questionnaire (CARQ-4) were used. The mean scores of the FoP-Q-12 and the CARQ-4 were 30.0 ± 10.4 and 16.1 ± 10.8, respectively, indicating relatively high levels of FoP. Both questionnaires showed excellent internal consistency coefficients, α = 0.895 and α = 0.915, respectively. The correlation between the two FoP questionnaires was r = 0.72. Female patients reported more FoP than male patients (d = 0.84 and d = 0.54, respectively). There was a nonlinear age dependency of FoP, with an increase found in the age range from 18 to 50 years and a decrease in the older age range. Radiation, chemotherapy, and antibody therapy, but not surgery, lead to an increase in FoP. Both questionnaires show good psychometric properties and can be recommended for use in an oncological routine. Female patients and patients in the middle-age range deserve special attention from healthcare providers.
