Medical, demographic and psychological correlates of fear of cancer recurrence (FCR) morbidity in breast, colorectal and melanoma cancer survivors with probable clinically significant FCR seeking psychological treatment through the ConquerFear study
PurposeDespite the prevalence of fear of cancer recurrence (FCR), understanding of factors underlying clinically significant FCR is limited. This study examined factors associated with greater FCR morbidity, according to a cognitive processing model, in cancer survivors who screened positively for clinically significant FCR seeking psychological treatment through the ConquerFear trial.MethodsParticipants had completed treatment for breast, colorectal or melanoma cancer 2 months to 5 years previously and scored ≥ 13/36 on the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). Hierarchical regression analyses examined associations between demographic, medical and psychological variables, namely metacognitions (MCQ-30), post-traumatic stress symptoms (IES-R) and FCR (FCRI total score).ResultsTwo hundred and ten (95%) of the 222 cancer survivors who consented to the ConquerFear trial completed the baseline questionnaire. Participants were predominantly (89%) breast cancer survivors. The final regression model accounted for 68% of the variance in FCR (demographic and medical variables 13%, metacognitions 26%, post-traumatic stress symptoms 28%). Negative metacognitive beliefs about worry and intrusive post-traumatic stress symptoms were significant individual correlates of FCR, but negative beliefs about worry did not significantly moderate the impact of intrusions on FCR morbidity.ConclusionsResults provide partial support for the cognitive processing model of FCR. Psychological factors were found to play an important role in FCR morbidity after controlling for demographic/medical factors. More intrusive thoughts and negative beliefs about worry were strong independent predictors of FCR morbidity. Cancer survivors with clinically significant FCR may benefit from assessment for intrusive thoughts and metacognitions and delivery of trauma- and/or metacognitive-based interventions accordingly.
Understanding how cancer patients actualise, relinquish, and reject advance care planning: implications for practice
Purpose Although advance care planning (ACP) is recognised as integral to quality cancer care, it remains poorly integrated in many settings. Given cancer patients’ unpredictable disease trajectories and equivocal treatment options, a disease-specific ACP model may be necessary. This study examines how Australian cancer patients consider ACP. Responses will inform the development of an Australian Cancer Centre’s ACP programme. Methods A constructivist research approach with grounded theory design was applied. Eighteen adults from lung and gastro-intestinal tumour streams participated. Participants first described their initial understanding of ACP, received ACP information, and finally completed a semi-structured interview assisted by the vignette technique. Qualitative inter-rater reliability was integrated. Results Participants initially had scant knowledge of ACP. On obtaining further information, their responses indicated that: For cancer patients, ACP is an individualised, dynamic, and shared process characterised by myriad variations in choices to actualise, relinquish, and/or reject its individual components (medical enduring power of attorney, statement of choices, refusal of treatment certificate, and advanced directive). Actualisation of each component involves considering, possibly conversing about, planning, and communicating a decision, usually iteratively. Reactions can change over time and are informed by values, memories, personalities, health perceptions, appreciation of prognoses, and trust or doubts in their substitute decision makers. Conclusion Findings endorse the value of routinely, though sensitively, discussing ACP with cancer patients at various time points across their disease trajectory. Nonetheless, ACP may also be relinquished or rejected and ongoing offers for ACP in some patients may be offensive to their value system.
Psychological intervention (ConquerFear) for treating fear of cancer recurrence: mediators and moderators of treatment efficacy
PurposeConquerFear is an efficacious intervention for fear of cancer recurrence (FCR) that demonstrated greater improvements than an attention control (relaxation training) in a randomized controlled trial. This study aimed to determine mediators and moderators of the relative treatment efficacy of ConquerFear versus relaxation.MethodsOne hundred and fifty-two cancer survivors completed 5 therapy sessions and outcome measures before and after intervention and at 6 months’ follow-up. We examined theoretically relevant variables as potential mediators and moderators of treatment outcome. We hypothesized that metacognitions and intrusions would moderate and mediate the relationship between treatment group and FCR level at follow-up.ResultsOnly total FCR score at baseline moderated treatment outcome. Participants with higher levels of FCR benefited more from ConquerFear relative to relaxation on the primary outcome. Changes in metacognitions and intrusive thoughts about cancer during treatment partially mediated the relationship between treatment group and FCR.ConclusionsThese results show that ConquerFear is relatively more effective than relaxation for those with overall higher levels of FCR. The mediation analyses confirmed that the most likely mechanism of treatment efficacy was the reduction in unhelpful metacognitions and intrusive thoughts during treatment, consistent with the theoretical framework underpinning ConquerFear.Implications for Cancer SurvivorsConquerFear is a brief, effective treatment for FCR in cancer survivors with early-stage disease. The treatment works by reducing intrusive thoughts about cancer and changing beliefs about worry and is particularly helpful for people with moderate to severe FCR.
Survivorship issues following treatment completion—results from focus groups with Australian cancer survivors and health professionals
Background The number of cancer survivors is increasing dramatically. Many survivors report long-term psychosocial, physical and other consequences. To understand the issues faced by Australian cancer survivors we conducted focus groups with cancer patients and health professionals. Methods Patients were identified through a peer support program at a major cancer treatment center (Peter Mac). Health professionals were also recruited from Peter Mac. Focus groups followed a semi-structured format based on themes identified from the literature. Questions focused on treatment completion, and 1 year post-treatment. Participants were also asked to suggest solutions to address identified issues. Focus groups were taped, transcribed, cross-checked for accuracy, and analyzed independently. Results The most common needs (in terms of both frequency and intensity) reported at treatment completion by both survivors and professionals were dealing with fatigue, anxiety about cancer recurrence, others expecting you to be back to normal, having to create new expectations about physical ability, and anxiety about leaving the hospital system. The most common needs at 1 year were anxiety about check-ups and results, and going into early menopause. The most frequently suggested ways of meeting these perceived needs were reassuring survivors the way they feel is normal and putting them in contact with others who have been through the same experience. Discussion There was a high level of congruence in the themes identified by survivors and health professionals. Implications for cancer survivors These results provide a clear direction for the development of resources to support cancer survivors following treatment completion.
Unmet needs in cancer patients: development of a supportive needs screening tool (SNST)
Goals of work A diagnosis of cancer can have a profound impact on the physical, emotional, psychological, social and spiritual areas of a person’s life. Supportive care services are directed towards this full range of issues associated with cancer. Identification of need is the first step in meeting supportive care concerns, but there is a lack of tools and processes regularly used in clinical practice. This article reports the first steps in the development of a supportive needs screening tool appropriate for use in an oncology outpatient setting. Materials and methods A review of the literature was undertaken, and a draft tool developed using a process of item reduction. A small pre-test followed by a pilot test with 87 patients attending Peter MacCallum Cancer Centre, Melbourne Australia was undertaken. Evaluation to identify usability and acceptability in clinical practice included descriptive statistics to profile patient needs and referrals generated by the supportive needs screening tool (SNST), interviews with a small sample of participants and surveys completed by staff. Main results The SNST was developed with 41 questions, the majority requiring a yes/no response. From the tool, a total of 1,085 needs were identified (mean = 12 needs/patient). A total of 264 referrals were generated, with 72% of patients receiving at least one referral. Patients and staff reported high acceptability. Conclusions The SNST has face validity and demonstrated usability in an ambulatory care oncology stetting, as first steps in instrument development. Further testing of reliability and validity are being undertaken.
The practical challenges of recruitment and retention when providing psychotherapy to advanced breast cancer patients
Goals of work The goal of the present study was to investigate recruitment issues relevant to psychotherapy trials for metastatic cancer patients. First, we undertook a literature review of the psychotherapy intervention research for metastatic cancer patients. Second, we piloted pragmatic recruitment methods for a couples’ intervention for women with metastatic breast cancer and their partners. Methods An extensive literature search was conducted to identify psychotherapy trials involving people with metastatic cancer published in peer-reviewed journals. Study characteristics and recruitment methodologies were examined. In the pilot study, we trialled the recruitment strategies of approaching participants at outpatients’ appointments, via letter, referral from the treating team and through direct advertising using two community support services. Results The literature search identified 1,905 potentially relevant articles, which were narrowed to 18 studies specifically involving metastatic cancer patients involving a professionally trained facilitator and a specified theoretical orientation. Limited information was found on recruitment rates and the success of recruitment strategies. Barriers to recruitment identified in the literature included degree of patient illness, lack of interest/perceived benefit, insufficient time, socio-demographic factors and negative clinician attitudes. Our pilot study identified 72 eligible couples of which 66 were approached. Our recruitment strategies resulted in six couples consenting (9.1%) but only three couples completing the study (4.5%). The main reasons for study refusal were the intervention was not needed, lack of interest, insufficient time, patient illness and travel distance. Conclusions Recruitment for couple-based psychotherapy interventions is challenging. More work is required on developing acceptable and feasible recruitment processes for metastatic cancer patients to be able to access support.
Using Metaphors to Assess Anticipatory Perceptions of Personal Death
The Revised Death Fantasy Scale (RDFS) is an 18-item measure based on metaphors of personal death. It was constructed to assess psychological aspects of contemplating personal death, at levels of awareness less conscious than those tapped by conventional self-report measures. It contains two subscales: Positive Metaphors and Negative Metaphors. In several studies the RDFS has shown evidence of reliability and validity. The scale may be potentially useful in health-related research and in the training and support of individuals whose work is related to death and dying.
Promoting healthy survivorship
Furthermore, improvements in quality of life with decreased levels of depression, better reports of self-esteem and body image, lowered levels of fatigue, better weight management and overall fitness have been demonstrated.
Clinical iron deficiency disturbs normal human responses to hypoxia
Iron bioavailability has been identified as a factor that influences cellular hypoxia sensing, putatively via an action on the hypoxia-inducible factor (HIF) pathway. We therefore hypothesized that clinical iron deficiency would disturb integrated human responses to hypoxia. We performed a prospective, controlled, observational study of the effects of iron status on hypoxic pulmonary hypertension. Individuals with absolute iron deficiency (ID) and an iron-replete (IR) control group were exposed to two 6-hour periods of isocapnic hypoxia. The second hypoxic exposure was preceded by i.v. infusion of iron. Pulmonary artery systolic pressure (PASP) was serially assessed with Doppler echocardiography. Thirteen ID individuals completed the study and were age- and sex-matched with controls. PASP did not differ by group or study day before each hypoxic exposure. During the first 6-hour hypoxic exposure, the rise in PASP was 6.2 mmHg greater in the ID group (absolute rises 16.1 and 10.7 mmHg, respectively; 95% CI for difference, 2.7-9.7 mmHg, P = 0.001). Intravenous iron attenuated the PASP rise in both groups; however, the effect was greater in ID participants than in controls (absolute reductions 11.1 and 6.8 mmHg, respectively; 95% CI for difference in change, -8.3 to -0.3 mmHg, P = 0.035). Serum erythropoietin responses to hypoxia also differed between groups. Clinical iron deficiency disturbs normal responses to hypoxia, as evidenced by exaggerated hypoxic pulmonary hypertension that is reversed by subsequent iron administration. Disturbed hypoxia sensing and signaling provides a mechanism through which iron deficiency may be detrimental to human health. ClinicalTrials.gov (NCT01847352). M.C.

A cross-sectional study of the prevalence and associations of iron deficiency in a cohort of patients with chronic obstructive pulmonary disease
ObjectivesChronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Iron deficiency, with or without anaemia, is associated with other chronic conditions, such as congestive heart failure, where it predicts a worse outcome. However, the prevalence of iron deficiency in COPD is unknown. This observational study aimed to determine the prevalence of iron deficiency in COPD and associations with differences in clinical phenotype.SettingUniversity hospital outpatient clinic.Participants113 adult patients (65% male) with COPD diagnosed according to GOLD criteria (forced expiratory volume in 1 s (FEV1): forced vital capacity (FVC) ratio <0·70 and FEV1 <80% predicted); with age-matched and sex-matched control group consisting of 57 healthy individuals.Main outcome measuresPrevalence of iron deficiency, defined as: any one or more of (1) soluble transferrin receptor >28.1 nmol/L; (2) transferrin saturation <16% and (3) ferritin <12 µg/L. Severity of hypoxaemia, including resting peripheral arterial oxygen saturation (SpO2) and nocturnal oximetry; C reactive protein (CRP); FEV1; self-reported exacerbation rate and Shuttle Walk Test performance.ResultsIron deficiency was more common in patients with COPD (18%) compared with controls (5%). In the COPD cohort, CRP was higher in patients with iron deficiency (median 10.5 vs 4.0 mg/L, p<0.001), who were also more hypoxaemic than their iron-replete counterparts (median resting SpO2 92% vs 95%, p<0.001), but haemoglobin concentration did not differ. Patients with iron deficiency had more self-reported exacerbations and a trend towards worse exercise tolerance.ConclusionsNon-anaemic iron deficiency is common in COPD and appears to be driven by inflammation. Iron deficiency associates with hypoxaemia, an excess of exacerbations and, possibly, worse exercise tolerance, all markers of poor prognosis. Given that it has been shown to be beneficial in other chronic diseases, intravenous iron therapy should be explored as a novel therapeutic option in COPD.
