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

ABSTRACT:

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.

Project description:ImportanceFear 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.ObjectiveTo characterize the prevalence of and risk factors for clinically significant fear of cancer recurrence in adult survivors of childhood cancer.Design, setting, and participantsThis 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 measuresClinically 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.ResultsThe 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 relevanceDecades 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.

Project description:ObjectiveInterventions for fear of recurrence (FOR) of cancer have nominal effects, perhaps due to limited integration of empirically supported skills. This pilot trial tested the acceptability and feasibility of a multimodal, mind-body resiliency intervention targeting FOR among survivors of various cancers.MethodsEarly stage cancer survivors 3-30 months post-treatment were recruited to participate in an eight-session in-person mind-body resiliency group intervention that taught relaxation skills, cognitive-behavioral techniques, healthy lifestyle behaviors, mindfulness meditation, and positive psychology skills all targeted for FOR. Primary outcomes were feasibility (enrollment rate, session attendance, survey completion, skills practice) and acceptability (enjoyableness, convenience, helpfulness, relevance). Patient-reported outcomes (FOR, uncertainty intolerance, cancer-related uncertainty, perceived stress, resiliency, positive affect, and coping skills) were collected at baseline, post-intervention, +1 month, and +3 months. Exit interviews assessed survivors' reported benefits.ResultsParticipants (N = 4 groups, 23 survivors, enrollment response rate = 58%) included survivors of seven common cancer types who were on average 12 months post-treatment. Attendance was high (M = 6.1 sessions), and 96% of survivors completed all surveys. Sustained increases in relaxation skills practice 3+ days/week were reported (baseline = 16%, post-intervention = 76%, +3 months = 71%). Most sessions (87%) were rated as highly or very highly acceptable. Moderate-to-large (d = 0.87) improvements in FOR severity were observed post-intervention (p < .01) and across assessments (p < .01), with similar changes observed in other patient-reported outcomes. Exit interviews revealed behavioral, cognitive, emotional, and existential benefits.ConclusionsThe targeted mind-body resiliency intervention shows promising acceptability, feasibility, and favorable changes in FOR and coping skills practice. Further adaptation and testing in a randomized trial are warranted. ClinicalTrials.govRegistration Number: NCT03695406.

Project description:ImportanceMost of the rapid increase in cutaneous melanoma incidence in the US has been localized disease that is treated surgically and is associated with high survival rates. However, little is known about the psychological well-being of survivors in the US.ObjectiveTo explore the lived experiences and fear of cancer recurrence among survivors of localized cutaneous melanoma.Design, setting, and participantsThis was a qualitative and survey-based study that used semistructured interviews and the Fear of Cancer Recurrence Inventory short form (FCRI-SF) survey tool with participants recruited from an academic dermatology practice affiliated with the University of Texas, Austin. Interviews were completed via telephone or in person from August 2021 to September 2022. Each of the 9 items in the FCRI-SF was rated on a 5-point Likert scale, scored from 0 to 4, with a maximum possible score of 36 points. Data analyses were performed from February 2022 to June 2023.Main outcomes and measuresSemistructured interviews were analyzed for themes and subthemes associated with the lived experiences of survivors of cutaneous melanoma. The FCRI-SF scores were tabulated, with scores of 13 or greater identifying potential cases of clinically significant fear of cancer recurrence.ResultsIn all, 51 participants (mean [SD] age, 49.5 [11.7] years; 34 [67%] female and 17 [33%] male) with a history of localized melanoma (stage 0-IIA) completed the interview and survey. Among them, 17 (33%) had survived a diagnosis of stage 0 melanoma, and the remainder, at least 1 invasive melanoma diagnosis (stage I-IIA). Semistructured interviews revealed several themes: (1) emotions surrounding follow-up appointments, (2) intensity of melanoma surveillance, (3) lifestyle changes regarding sun exposure, and (4) thoughts about life and death. Thirty-eight of 51 participants had an FCRI-SF score above the threshold for clinical fear of cancer recurrence.Conclusions and relevanceThis qualitative and survey-based study found that despite having an excellent prognosis, some survivors of localized melanoma, even those who had stage 0, have high rates of fear of cancer recurrence and intense survivorship experiences that affect their psychological well-being.
