A novel clinician-delivered intervention to reduce fear of recurrence in breast cancer survivors: Results from a Phase I/II implementation study (CIFeR_2).

OBJECTIVE: Fear of cancer recurrence (FCR) is highly prevalent, however there is no formal training for clinicians to address FCR. A novel brief clinician intervention to help patients manage FCR (Clinician Intervention to Reduce Fear of Recurrence (CIFeR)) was shown to be feasible, acceptable, and reduced FCR in breast cancer patients in a pilot study. We now aim to explore the barriers and facilitators of implementing CIFeR within routine oncology practice in Australia. METHODS: This multicentre, single-arm Phase I/II implementation study recruited surgical, medical and radiation oncologists who treat women with early breast cancer. Participating clinicians completed online CIFeR training and were asked to use CIFeR for the next 6 months. Questionnaires were administered before (T0), immediately after (T1), then 3 (T2) and 6 months (T3) after training to assess confidence in addressing FCR and Proctor Implementation outcomes. The primary outcome was adoption at T2. Secondary outcomes were self-efficacy in FCR management, acceptability, feasibility, costs, barriers and facilitators of implementation. RESULTS: Fifty-two clinicians consented of whom 37 completed the CIFeR intervention training. Median age of participants was 41.5 (range 29-61), 73% were female and 51% were medical oncologists. The primary endpoint was met, with CIFeR adopted by 82%. Clinician intervention delivery took 7.4 min on average and was deemed acceptable, appropriate and feasible. Self-efficacy in managing FCR improved significantly across all domains (p < 0.001). Lack of time was the greatest barrier to routine CIFeR_2 implementation. CONCLUSIONS: A structured brief, low-cost clinician intervention to reduce FCR is useful, acceptable and improved self-efficacy with FCR management. Fear of cancer recurrence training should be incorporated into communication skills training of oncologists and surgeons.

Differentiating melancholic and non-melancholic depression via biological markers: A review.

OBJECTIVES: Melancholia is a severe form of depression that is typified by greater genetic and biological influence, distinct symptomatology, and preferential response to physical treatment. This paper sought to broadly overview potential biomarkers of melancholia to benefit differential diagnosis, clinical responses and treatment outcomes. Given nuances in distinguishing melancholia as its own condition from other depressive disorder, we emphasised studies directly comparing melancholic to non-melancholic depression. METHODS: A comprehensive literature search was conducted. Key studies were identified and summarised qualitatively. RESULTS: 105 studies in total were identified. These studies covered a wide variety of biomarkers, and largely fell into three domains: endocrinological (especially cortisol levels, particularly in response to the dexamethasone suppression test), neurological, and immunological (particularly inflammatory markers). Less extensive evidence also exists for metabolic, genetic, and cardiovascular markers. CONCLUSIONS: Definitive conclusions were predominantly limited due to substantial heterogeneity in how included studies defined melancholia. Furthermore, this heterogeneity could be responsible for the between- and within-group variability observed in the candidate biomarkers that were examined. Therefore, clarifying these definitional parameters may help identify underlying patterns in biomarker expression to improve diagnostic and therapeutic precision for the depressive disorders.

Protocol of an implementation study of a clinician intervention to reduce fear of recurrence in cancer survivors (CIFeR_2 implementation study).

BACKGROUND: Fear of cancer recurrence (FCR) affects 50-70% of cancer survivors with 30% reporting an unmet need for help with managing FCR. Patients indicate desire to discuss FCR with clinicians, however clinicians indicate discomfort with managing FCR and no formal educational interventions on how to discuss FCR or worry exists for oncology clinicians. Our team developed a novel clinician-driven brief education intervention to help patients manage FCR (the Clinician Intervention to Reduce Fear of Recurrence (CIFeR) intervention). In earlier work, we demonstrated the feasibility, acceptability, and efficacy of CIFeR in reducing FCR in breast cancer patients. We now aim to explore the barriers and facilitators to implementing this low-cost brief intervention within routine oncology practice in Australia. The primary objective is to assess the adoption of CIFeR in routine clinical practice. Secondary objectives are to identify the uptake and sustainability, perceived acceptability, feasibility, costs, barriers and facilitators of implementation of CIFeR in routine clinical practice, and to assess whether training in CIFeR increases clinicians' self-efficacy in managing FCR with their patients. METHODS: This multicentre, single-arm Phase I/II implementation study will recruit medical and radiation oncologists and oncology surgeons who treat women with early breast cancer. Participants will complete online CIFeR training. They will then be asked to use CIFeR with suitable patients for the next 6 months. Participants will complete questionnaires prior to, immediately after and 3 and 6 months after training to assess confidence addressing FCR, and 3 and 6 months after training to assess Proctor Implementation outcomes. At 6 months, they will also be asked to participate in a semi-structured telephone interview to elicit their feedback about barriers and facilitators to using CIFeR in routine clinical practice. DISCUSSION: This study will provide further data to support the routine use of an evidence-based, clinician-lead educational intervention to reduce FCR in breast cancer patients. Additionally, this study will identify any barriers and facilitators to implementing the CIFeR intervention in routine care and evidence for integration of FCR training into oncology communication skills education.

Patients' and oncologists' perspectives on a novel Clinician-led Fear of Cancer Recurrence (CIFeR) Intervention.

PURPOSE: Despite strong demand from breast cancer survivors, there is a dearth of flexibly delivered, accessible psychological interventions addressing fear of cancer recurrence (FCR). This study aimed to explore patients' and clinicians' perspectives concerning the experience, utility and barriers to a novel clinician-led FCR intervention (CIFeR). METHODS: Twenty female participants (mean age, 59.8, SD = 11.43), diagnosed with early-stage breast cancer (mean years since diagnosis = 2.8, SD = 1.37 years) participated in telephone interviews, and their five oncologists completed a semi-structured electronic survey. Thematic qualitative analyses were performed on interview transcripts and survey responses. RESULTS: Findings indicated both patients and clinicians were positive about CIFeR with perceived cognitive, behavioural and emotional benefits of CIFeR most pronounced for patients with clinically significant FCR. All patients, however, found that receiving CIFeR (especially the tailored prognostic information) from their oncologists with whom they had a long-standing relationship added a much-needed human element to addressing FCR. Similarly, clinicians valued CIFeR as a clear and consistent way to address unmet needs around FCR, with some barriers around time, language and cultural issues noted. CONCLUSION: Overall, all participants perceived CIFeR as strongly beneficial in reducing FCR and related worries, thus warranting further evaluation of its utility in clinical practice.

Novel Clinician-Lead Intervention to Address Fear of Cancer Recurrence in Breast Cancer Survivors.

PURPOSE: Fear of cancer recurrence (FCR) affects 50%-70% of cancer survivors. This multicenter, single-arm study sought to determine the participant-rated usefulness of an oncologist-delivered FCR intervention. METHODS: Women who completed treatment for early breast cancer (could be receiving endocrine therapy) with baseline FCR > 0 were invited to participate. FCR was measured using a validated 42-item FCR Inventory. The brief oncologist-delivered intervention entailed (1) FCR normalization; (2) provision of personalized prognostic information; (3) recurrence symptoms education, (4) advice on managing worry, and (5) referral to psycho-oncologist if FCR was high. FCR, depression, and anxiety were assessed preintervention (T0), at 1 week (T1), and 3 months (T2) postintervention. The primary outcome was participant-rated usefulness. Secondary outcomes included feasibility and efficacy. RESULTS: Five oncologists delivered the intervention to 61/255 women invited. Mean age was 58 ± 12 years. Mean time since breast cancer diagnosis was 2.5 ± 1.3 years. Forty-three women (71%) were on adjuvant endocrine therapy. Of 58 women who completed T1 assessment, 56 (97%) found the intervention to be useful. FCR severity decreased significantly at T1 (F = 18.5, effect size = 0.39, P < .0001) and T2 (F = 24, effect size = 0.68, P < .0001) compared with baseline. There were no changes in unmet need or depression or anxiety. Mean consultation length was 22 minutes (range, 7-47 minutes), and mean intervention length was 8 minutes (range, 2-20 minutes). The intervention was perceived as useful and feasible by oncologists. CONCLUSION: A brief oncologist-delivered intervention to address FCR is useful and feasible, and has preliminary efficacy in reducing FCR. Plans for a cluster randomized trial are underway.
