A 1-year prospective study of individual variation in distress, and illness perceptions, after treatment for breast cancer

Can illness representations be used to understand pain experienced in breast cancer survivorship-a cross-sectional study

BACKGROUND

Chronic pain is a recognised long-term consequence associated with breast cancer and its treatment; however, it is often underdiagnosed and undertreated. This study aims to explore the associations between illness representations, chronic cancer pain, and HRQoL in women who have survived breast cancer.

DESIGN AND METHODS

A cross-sectional online survey design was used. Data from 182 women who participated in the survey were analysed.

RESULTS

Chronic cancer pain was reported by 66% of respondents. Using the BPI-SF (score 0-10), participants were categorised into one of four pain categories: no chronic pain (BPI score 0; 34.1%), mild pain (BPI score 1-3; 35.7%), moderate pain (BPI score 4-6; 25.3%), and severe pain (BPI score 7 + ; 4.9%). The main findings were that having a strong illness identity (IPQ-R subscale which assesses the number of symptoms an individual attributes to their illness) was found to be a significant predictor of pain severity (OR 1.21 (95% CI 1.07-1.37), p = 0.003). Furthermore, HRQoL was significantly associated and predictive of pain severity (OR 0.97 (95% CI 0.95-0.99), p < 0.001). An additional finding was that not being in paid work was strongly associated with being in a higher pain category (OR 5.92 (95% CI 1.84-19.05), p = 0.003).

CONCLUSIONS

The findings of this study highlight the high prevalence of chronic cancer pain experienced by this population. Results show that dimensions of illness representations are associated with chronic cancer pain experienced by breast cancer survivors. Furthermore, having a strong illness identity and HRQoL were found to be independent, significant predictors of pain severity.

IMPLICATIONS FOR CANCER SURVIVORS

These findings demonstrate that chronic pain is an unmet clinical need experienced by breast cancer survivors, which is associated with reduced overall HRQoL. Therefore, consideration is needed regarding the assessment and management of chronic pain experienced by this population.

Psychometric properties of the Malay version of the Illness Cognition Questionnaire among cancer patients in Malaysia

OBJECTIVE

The Illness Cognition Questionnaire (ICQ) was translated from its original English version to the Malay version for this research, adapted the Malay language version of the ICQ (ICQ-M) for use in cancer patients, and assessed the internal consistency, content, face, construct, convergent, discriminant and concurrent validity of the ICQ-M among a cohort of cancer patients with mixed cancer types in Malaysia.

METHOD

Initially, the ICQ was translated into Malay and back-translated, and its content and face validity were evaluated. Then, 346 cancer patients with various cancer types received the ICQ-M, and its internal consistency, convergent, discriminant, construct, and concurrent validity were evaluated.

RESULTS

The ICQ-M and its domains had acceptable internal consistency with Cronbach's α ranging from 0.742 to 0.927. Construct validity assessment demonstrated that the ICQ-M consists of 17 items designated in two domains with good convergent and discriminant validity. The ICQ-M and its domains also had moderate correlations with the Acceptance and Action Questionnaire II, which denotes that the ICQ-M had acceptable concurrent validity.

CONCLUSION

The ICQ-M had good psychometric properties and is now available to measure the illness cognition of cancer patients in Malaysia.

Patient and family members' experiences with language and environment when receiving bad news: A qualitative exploratory study

OBJECTIVES

Receiving bad news about one's health can be devastating, yet little is known about how the therapeutic nature of the environment where bad news is delivered affects the experience. The current study aimed to explore how patients and their families were affected by the language and the built, natural, social, and symbolic environments when receiving bad news, through the Therapeutic Landscapes theoretical framework.

METHODS

Patients diagnosed with a life-limiting illness living in regional Victoria who had a hospital admission within 24 months and a diagnostic/prognostic conversation were invited to participate, as well as a family member who witnessed the conversation. Participants were recruited through social media and snowballing, resulting in 14 online semi-structured interviews being conducted between November 2021 and March 2022, audio-recorded, and transcribed verbatim. Reflexive thematic analysis was used to develop the themes.

RESULTS

Fourteen semi-structured interviews were conducted with women aged between 30 and 77 years. Interviews lasted between 45 and 120 minutes, with an average of 69 minutes, and were conducted online or via mobile phone. Four central themes were developed: "Hearing bad news for the first time," "Preferences for having hard conversations," "Creating a sense of safety for ongoing care," and "The therapeutic nature of the ward."

SIGNIFICANCE OF RESULTS

This body of work will help inform practice and future policy regarding bad news delivery and the design and aesthetics of environments where bad news is delivered. It is essential that bad news is delivered within a quiet, calm, and emotionally safe environment within a supportive therapeutic relationship.

Psychological interventions for women with non-metastatic breast cancer

BACKGROUND

Breast cancer is the most common cancer affecting women worldwide. It is a distressing diagnosis and, as a result, considerable research has examined the psychological sequelae of being diagnosed and treated for breast cancer. Breast cancer is associated with increased rates of depression and anxiety and reduced quality of life. As a consequence, multiple studies have explored the impact of psychological interventions on the psychological distress experienced after a diagnosis of breast cancer. This review is an update of a Cochrane Review first published in 2015.

OBJECTIVES

To assess the effect of psychological interventions on psychological morbidities and quality of life among women with non-metastatic breast cancer.  SEARCH METHODS: We searched the Cochrane Breast Cancer Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov up to 16 March 2021. We also scanned the reference lists of relevant articles.

SELECTION CRITERIA

Randomised controlled trials that assessed the effectiveness of psychological interventions for women with non-metastatic breast cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently appraised, extracted data from eligible trials, and assessed risk of bias and certainty of the evidence using the GRADE approach. Any disagreement was resolved by discussion. Extracted data included information about participants, methods, the intervention and outcomes.

MAIN RESULTS

We included 60 randomised controlled trials comprising 7998 participants. The most frequent reasons for exclusion were non-randomised trials and the inclusion of women with metastatic disease. The updated review included 7998 randomised women; the original review included 3940 women. A wide range of interventions was evaluated. Most interventions were cognitive- or mindfulness-based, supportive-expressive, and educational. The interventions were mainly delivered face-to-face (56 studies) and in groups (50 studies) rather than individually (10 studies). Most intervention sessions were delivered on a weekly basis with an average duration of 14 hours. Follow-up time ranged from two weeks to 24 months.  Pooled standardised mean differences (SMD) from baseline indicated that the intervention may reduce depression (SMD -0.27, 95% confidence interval (CI) -0.52 to -0.02; P = 0.04; 27 studies, 3321 participants, I2 = 91%, low-certainty evidence); anxiety (SMD -0.43, 95% CI -0.68 to -0.17; P = 0.0009; 22 studies, 2702 participants, I2 = 89%, low-certainty evidence); mood disturbance in the intervention group (SMD -0.18, 95% CI -0.31 to -0.04; P = 0.009; 13 studies, 2276 participants, I2 = 56%, low-certainty evidence); and stress (SMD -0.34, 95% (CI) -0.55 to -0.12; P = 0.002; 8 studies, 564 participants, I2 = 31%, low-certainty evidence). The intervention is likely to improve quality of life in the intervention group (SMD 0.78, 95% (CI) 0.32 to 1.24; P = 0.0008; 20 studies, 1747 participants, I2 = 95%, low-certainty evidence). Adverse events were not reported in any of the included studies.

AUTHORS' CONCLUSIONS

Based on the available evidence, psychological intervention may have produced favourable effects on psychological outcomes, in particular depression, anxiety, mood disturbance and stress. There was also an improvement in quality of life in the psychological intervention group compared to control group. Overall, there was substantial variation across the studies in the range of psychological interventions used, control conditions, measures of the same outcome and timing of follow-up.

The Significance of Adaptation and Coping with Disease among Patients with Diagnosed Gynaecological Cancer in the Context of Disease Acceptance

Uterine/endometrial and ovarian tumours are among the most common gynaecological cancers. Adaptation to cancer encompasses a variety of complex behavioural, cognitive, and emotional processes. The purpose of mental adaptation is to alleviate emotional discomfort and regain mental stability. The aim of the study was to assess the influence of adaptation and coping with gynaecological cancer on the level of disease acceptance among the studied women. The study included 81 patients diagnosed with gynaecological cancer. Mental adaptation to cancer was measured using the Min-Mac scale, disease acceptance was measured using the AIS and the level of adaptation was measured using the CAPS. The average AIS score was 26.65 ± 8.85 points. Adaptation and coping methods did not vary significantly depending on the diagnosed type of cancer. The constructive style of fighting the disease prevailed (45.11 ± 6.01). The AIS scores correlated significantly and positively with the intensity of the constructive style of mental adaptation, and negatively with the intensity of the destructive style. The studied group of patients with gynaecological cancer displayed a moderate level of disease acceptance, the constructive style of adaptation was the most prevalent, and the location of the cancer did not have an effect on coping mechanisms.

The Significance of Patient-Reported Outcomes for Metastatic Breast Cancer Patients

BACKGROUND

Breast cancer is still the most common malignancy in women worldwide. Once metastasized, breast cancer treatment primarily aims at reducing symptom burden, thereby trying to maintain and improve a patient´s quality of life (QoL), delaying disease progression, and prolonging survival. Curing the disease is not possible in the palliative setting. To better understand metastatic breast cancer patients, their symptoms and wishes, which are important for treatment-decision making and outcome, patient-reported outcomes (PROs) are of great importance, giving an impression of what really matters to and concerns a patient.

SUMMARY

Many advances have been made to implicate PROs in clinical trials, non-interventional studies, registries, and clinical routine care of metastatic breast cancer. For example, large phase III trials like PALOMA-3 (NCT01942135), MONALEESA-7 (NCT02278120), HER2CLIMB (NCT02614794), and KEYNOTE-119 (NCT02555657) trials implemented PROs in their trial design to assess the QoL of their trial patients. Also, non-interventional studies on metastatic breast cancer, like e.g., the NABUCCO study (IOM-02240), and prospective non-interventional, multicenter registries e.g., the tumor registry breast cancer (NCT01351584) or the breast cancer registry platform OPAL (NCT03417115), have implemented PROs to assess QoL during the anti-cancer treatment periods of the patients. Key Message: Using PROs in metastatic breast cancer can support shared treatment-decision making and management of symptoms, eventually leading to an improvement in QoL. Progressively, regulatory authorities take PROs into consideration for the approval of new drugs. Hence, the implication of PROs in cancer treatment, and especially in MBC, is of significant value.

Les représentations de la maladie : choix des outils de mesure et applications dans le champ du cancer

Objectif : Dresser un bilan des outils quantitatifs disponibles pour mesurer les représentations de la maladie et analyser leur utilisation empirique auprès de patients atteints de cancer.

Matériel et méthodes : Revue de la littérature.

Résultats : Sept outils de mesure des représentations de la maladie existent dont un spécifique au cancer. L’Illness Perception Questionnaire est utilisé dans 29 des 33 études retenues.

Conclusion : Associer ces échelles avec des méthodes reposant sur des approches davantage centrées sur le contexte socioculturel semble à privilégier.

Longitudinal Trends in Illness Perception and Depression during Adjuvant Breast Cancer Endocrine Therapy: A Prospective Observational Study

This study aimed to identify the changes in the illness perceptions and depression of women with breast cancer, undergoing AET, at three time points (i.e., before initiating AET, 3 months follow-up, and 12 months follow-up). We investigated the interaction effects of their demographic and clinical characteristics on illness perception changes over time. Furthermore, factors including the patient’s characteristics and illness perceptions associated with depressive symptoms 1 year after starting AET were explored. Illness perception and depressive symptoms were assessed with the brief illness perception questionnaire and the Center for Epidemiologic Studies Depression Scale, in a prospective study of 150 women. The changes in illness perceptions and depression between the three time points were analyzed using repeated measures ANOVA. The factors associated with depressive symptoms were identified using regression analysis. Illness perception improved overall over the 12 months. However, more patients perceived their illness as chronic, experienced more symptoms, and developed negative beliefs that treatment could not control their disease. Patients’ depressive symptoms decreased significantly. Depression at the baseline, cancer stage, and the perception of personal control were highly associated with depression after 12 months. These findings suggest that healthcare providers should offer appropriate interventions to patients, for managing symptoms, having a positive belief that treatment can control their disease, and preventing long-term depressive symptoms.

Sensation seeking and neuroticism in fear conditioning and extinction: The role of avoidance behaviour

Maladaptive avoidance behaviour, a key symptom of anxiety-related disorders, prevents extinction learning and maintains anxiety. Individual personality traits likely influence avoidance propensity: high sensation-seeking may decrease avoidance, thereby increasing extinction, and neuroticism may have the reverse effect. However, research on this is scarce. Using a naturalistic conditioned avoidance paradigm, 163 women underwent differential fear acquisition to a conditioned stimulus (CSplus). Next, during extinction, participants could either choose a risky shortcut, anticipating shock signalled by CSplus, or a time-consuming avoidance option (lengthy detour). Across participants, increased skin conductance (SCR) acquisition learning predicted subsequent instrumental avoidance. Avoidance, in turn, predicted elevated post-extinction SCR and shock-expectancy, i.e., 'protection-from-extinction'. Mediation analyses revealed that sensation seeking decreased protection-from-extinction-both for shock-expectancy and SCR-via attenuating avoidance. Neither sensation seeking nor neuroticism were related to acquisition learning and neuroticism was neither related to avoidance nor extinction. Transcranial direct currentstimulation administered before extinction did not influence present results. Results highlight the important role of elevated avoidance propensity in fear maintenance. Results moreover provide evidence for reduced sensation-seeking and increased acquisition learning to be avoidance-driving mechanisms. Since approach-avoidance conflicts are faced by anxiety patients on a daily basis, strengthening sensation-seeking-congruent attitudes and approach behaviours may optimize individualized treatment.

Predicting Pain Trajectories in the One Year Following Breast Cancer Diagnosis-An Observational Study

The impact of psychosocial vulnerability on pain in the year following breast cancer diagnosis has been little studied. To identify a score of psychosocial vulnerability (cognitive, emotional, quality of life and precariousness parameters) as a predictor of a pain trajectory, we conducted an observational prospective study and included women with newly diagnosed breast cancer. One year follow-up with 3 visits (day of breast cancer diagnosis; 6 and 12 months) aimed to identify distinct pain-time trajectories. Baseline psychosocial vulnerability was characterized by z-score transformation, a higher score representing a more vulnerable patient. A total of 89 patients were included (59.3 ± 10.7 years). Two trajectories of pain were identified-"Transient Pain trajectory" (TP) (39/89 patients) and "Persistent Pain trajectory" (PP) (50/89). A significant difference of pain over time between trajectories (PP vs. TP at 6 months: 2.23 ± 0.23 vs. 0.27 ± 0.09, p < 0.001) was observed. Psychosocial vulnerability showed a large effect size (d, -0.82; 95% CI, -1.25 to -0.38; p < 0.001) and a higher score in "Persistent pain trajectory" (PP vs. TP: 0.12 ± 0.36 vs. -0.14 ± 0.26, p < 0.001). A predictive vulnerability marker of pain development is proposed and could be used at cancer diagnosis to orientate the care pathway of patients experiencing breast cancer.

Primary breast cancer and health related quality of life in Spanish women: The EpiGEICAM case-control study

This study evaluates the impact of breast cancer (BC) in health related quality of life (HRQL) and in psychological distress (PD) during the initial phases of the disease and looks for contributing factors. A multicentric case-control study, EpiGEICAM, was carried out. Incident BC cases and age- and residence- matched controls were included. Clinical, epidemiological, HRQL (SF-36) and PD information (GHQ-28) was collected. We used multivariable logistic regression models to estimate OR of low HRQL and of PD in cases compared to controls, and to identify factors associated with low HRQL and with PD. Among 896 BC cases and 890 control women, cases had poorer scores than both, the reference population and the control group, in all SF-36 scales. BC women with lower education, younger, active workers, never smokers, those with comorbidities, in stage IV and with surgical treatment had lower physical HRQL; factors associated with low mental HRQL were dissatisfaction with social support, being current smoker and having children. Cases had a fivefold increased odds of PD compared to controls. Managing comorbidities and trying to promote social support, especially in younger and less educated women, could improve well-being of BC patients.

Pessimism predicts anxiety and depression in breast cancer survivors: A 5-year follow-up study

OBJECTIVE

We investigated the prevalence of anxiety and depression at diagnosis and at 1, 3, and 5 years after breast cancer diagnosis. We hypothesized that a low level of optimism (pessimism) at diagnosis could predict change in anxiety and depression 5 years later.

METHODS

Three hundred sixty-seven women with operable breast cancer were included, and data were collected at all five-time points for 293 of these. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS). Dispositional optimism/pessimism was measured using the Life Orientation Test-Revised (LOT-R). Frequency analysis was used to determine the prevalence of anxiety and depression. Logistic regression was used to examine dispositional optimism/pessimism as a predictor of change in anxiety and depression 5 years after diagnosis.

RESULTS

The prevalence rates of anxiety and depression 5 years after diagnosis were 26.3% and 9.6%, respectively. Predictors of change in anxiety 5 years after diagnosis were pessimism (odds ratio [OR] = 0.82; 95% confidence interval [CI]: 0.76-0.89, P < .001); younger age (OR = 0.96; 95% CI: 0.93-0.99, P = .005); and anxiety at diagnosis (OR = 2.41; 95% CI: 1.33-4.37, P = .004). Predictors of change in depression 5 years after diagnosis were pessimism (OR = 0.84; 95% CI: 0.77-0.94, P < .001) and comorbidity (OR = 1.51, 95% CI: 1.10-2.06, P = 0.01).

CONCLUSION

Anxiety and depression did not decrease after the first postoperative year. Pessimism was a predictor of change in both anxiety and depression 5 years after breast cancer diagnosis.

Optimism outweighs neuroticism and anxiety sensitivity to predict insomnia symptoms in women after surgery for breast cancer

PURPOSE

Insomnia symptoms are common among women who have undergone surgery for breast cancer. Personality traits are also believed to have an impact on sleep. However, there are no reports to address the effects of personality traits on sleep in women with breast cancer. This study examined the separate and competing roles of neuroticism, anxiety sensitivity, and optimism in predicting post-surgery insomnia symptoms.

METHODS

Women with breast cancer (n = 749) were enrolled the week prior to surgery and required to complete a demographic questionnaire, the Chinese version of Neuroticism subscale of NEO-Five Factor Inventory (CV-N-NEO-FFI), Anxiety Sensitivity Index-3 (CV-ASI-3), and Life Orientation Test-Revised (CV-LOT-R). Four weeks post-surgery, the Chinese version of Insomnia Severity Index (CV-ISI) was administered to evaluate insomnia symptoms.

RESULTS

Neuroticism (β = 0.317, p < 0.001), anxiety sensitivity (β = 0.220, p < 0.001), and optimism (β = - 0.332, p < 0.001) could predict post-surgery insomnia symptoms. When putting them together into one stepwise regression, optimism (β = - 0.215, p < 0.001) became the statistically most important predictor for insomnia symptoms. Optimism suppressed the predictions of insomnia symptoms provided by neuroticism (β = 0.114, p < 0.001) and anxiety sensitivity (β = 0.079, p < 0.001).

CONCLUSION

Neuroticism and anxiety sensitivity positively predicted insomnia, but optimism negatively predicted insomnia. In particular, optimism plays a more important role in post-surgery insomnia symptoms in women with breast cancer compared to neuroticism and anxiety sensitivity. Sleep intervention in women with breast cancer should focus on enhancing their optimism level.

Identifying and predicting distinct distress trajectories following a breast cancer diagnosis - from treatment into early survival

OBJECTIVE

Most longitudinal studies on distress in breast cancer (BC) patients reported a continuous decrease after diagnosis, however masking individual variations in patterns of adjustment. We sought to identify distinct trajectories of distress during primary treatment into survivorship and to identify variables that are determinants of which patient follows which type of adjustment trajectory.

METHODS

Psychological distress was measured at four significant time points (after surgery/biopsy, at treatment completion, two and six months thereafter) among 181 newly diagnosed BC patients. A latent growth mixture modeling approach was used to identify distinct distress trajectories.

RESULTS

Four distress trajectories were identified: a 'resilient' pattern (73.1%), a 'high-remitting' (7.7%) trajectory, a 'delayed' increase in distress (7.9%), and a constantly high 'chronic' distress (11.3%) pattern. High perceived burden from physical symptoms at treatment completion encompassed a higher chance for the 'high-remitting' and 'chronic' distress trajectory. High self-efficacy at baseline increased chances for the 'high-remitting' pattern. Neither type of treatment, demographic or medical characteristics, nor baseline distress reliably predicted distress trajectories.

CONCLUSION

The majority of BC patients adjust well through a demanding treatment period. High patient-perceived burden from physical symptoms, and high coping self-efficacy is suggesting a transient, self-limiting distress trajectory, while patients experiencing constant 'chronic' distress, and those developing distress following treatment completion only cannot be identified by a single, initial assessment. Only systematic tracking with repeated measurement extending into survivorship can eliminate this problem. Interventions should aim at reducing the impact of symptom burden on women's every-day life and on strengthening coping-self efficacy.

Promoting Emotional Well-Being in Older Breast Cancer Patients: Results From an eHealth Intervention

Breast cancer is the most common cancer in women worldwide, with increases in diagnoses at all ages. Due to several age-related factors, older breast cancer patients show particular difficulties in adjusting to breast cancer and its related treatments. One consistent indicator of vulnerability to long-term complications is emotional distress occurring within 3 months of diagnosis. Thus, it is critical to develop early interventions specifically aimed at mitigating distress and promoting emotional wellbeing in older breast cancer patients. By taking advantage of the opportunities of online interventions, the present study aimed to test the efficacy of a 2 weeks e-health stress inoculation training (SIT) intervention on emotion regulation and cancer-related well-being, compared with a control group without such intervention. Twenty-nine women with a diagnosis of breast cancer, who had received radical surgery and who were suitable candidates for adjuvant chemotherapy with anthracyclines and taxanes (mean age = 62.76; SD = 6.19) voluntarily took part in the current study after giving written informed consent. To test intervention efficacy, self-report questionnaires were administered to all participants at baseline, at the end of the 2 weeks intervention, and 3 months after the end of the intervention. Results showed that after 2 weeks of ehealth intervention, patients did not achieve significant change, however, they significantly reduced emotional suppression and increased cancer-related emotional well-being 3 months after the end of the intervention. Furthermore, by monitoring at a distance the emotional experience during the online intervention, we found an increase in relaxation and a reduction of anxiety. Finally, patients in the experimental group reported a good level of acceptance of the ehealth intervention. To conclude, designing and developing eHealth interventions as part of the regular care path for breast cancer patients of all ages represents both a challenge and an opportunity; in particular, online interventions can be an important step in universal psychosocial care within a tiered model of care.

Negativity bias in false memory: moderation by neuroticism after a delay

The negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic associates of an unpresented word (the critical lure). Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately (Experiment 1), individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay (Experiment 2), individuals higher in neuroticism maintained greater false memory for negative versus positive critical lures, but those lower in neuroticism showed no difference in false memory between negative and positive critical lures. Possible mechanisms and implications for mental health disorders are discussed.

Survivorship care plans have a negative impact on long-term quality of life and anxiety through more threatening illness perceptions in gynecological cancer patients: the ROGY care trial

Purpose

Prior results from the registration system oncological gynecology (ROGY) care trial showed that survivorship care plans (SCPs) increased threatening illness perceptions in gynecological cancer survivors, but it remained unclear whether this would result in poorer physical and psychosocial outcomes. The aim of the current study is to assess the direct and indirect effects of SCPs on health-related quality of life (HRQoL) and anxiety and depression, through illness perceptions.

Methods

Twelve hospitals in the South of the Netherlands were randomized to providing ‘SCP care’ or ‘usual care.’ Newly diagnosed endometrial and ovarian cancer patients completed questionnaires after initial treatment (endometrial, 221 [75%]; ovarian, 174 [71%]) and after 6, 12, and 24 months. SCPs were automatically generated after initial treatment by the oncology providers through the web-based ROGY. Illness perceptions were measured after initial treatment and HRQoL and anxiety and depression after 6, 12, and 24 months.

Results

Structural equation models showed that endometrial cancer patients who experienced more symptoms or concern due to the SCP reported worse social functioning (β = − 0.82; p = 0.01) and more fatigue, insomnia, pain, and anxiety (β = 0.58–0.86, p < 0.05) within 12 months after treatment. Ovarian cancer patients who had lower trust that the treatment would cure their disease due to the SCP reported worse emotional functioning 6 months after treatment (β = 0.27, p = 0.02).

Conclusions

Current results show that SCPs may have negative effects on HRQoL and anxiety in patients who experience more threatening illness perceptions due to the SCP. We should be aware of the potential negative consequences of SCPs.

Predictors of emotional distress a year or more after diagnosis of cancer: A systematic review of the literature

Objective

Why some people recover emotionally after diagnosis and treatment of cancer and others do not is poorly understood. To identify factors around the time of diagnosis that predict longer‐term distress is a necessary step in developing interventions to reduce patients' vulnerability. This review identified the demographic, clinical, social, and psychological factors available at or within 3 months of diagnosis that are reliable predictors of emotional distress at least 12 months later.

Methods

A systematic search of literature for prospective studies addressing our research question and predicting a range of distress outcomes was conducted. Thirty‐nine papers (reporting 36 studies) were subjected to narrative synthesis of the evidence.

Results

There was no consistent evidence that demographic, clinical, or social factors reliably predicted longer‐term distress. Of the psychological factors examined, only baseline distress (significant in 26 of 30 relevant papers; 24 of 28 studies) and neuroticism (significant in all 5 papers/studies that examined it) consistently predicted longer‐term distress. The heterogeneity of included studies, particularly in populations studied and methodology, precluded meta‐analytic techniques.

Conclusions

This review supports current clinical guidance advising early assessment of distress as a marker of vulnerability to persistent problems. Additionally, neuroticism is also indicated as a useful marker of vulnerability. However, the review also highlights that more sophisticated research designs, capable of identifying the psychological processes that underlie the association between these marker variables and persistent distress, are needed before more effective early interventions can be developed.

The Relationship between Physical Activity Intensity and Mental Health Status in Patients with Breast Cancer

The aim of this study was to investigate the correlation between physical activity (PA) level and mental health status in a population-based sample of Korean female patients with breast cancer. Our analysis included 76 patients with breast cancer and 44 healthy controls. The Korean versions of the International Physical Activity Questionnaire (IPAQ), Beck Depressive Inventory (BDI), State-Trait Anxiety Inventory-KY (STAI-KY), and Somatosensory Amplification Scale (SSAS), and Quality of Life (QOL) scale were assessed. The frequency of moderate PA level in breast cancer patients was significantly lower than that of healthy control subjects (t = -2.6; P = 0.011). In turn, the incidence of low PA level in breast cancer patients was significantly higher than that observed in healthy controls (t = 2.85; P = 0.005). A moderate PA level was inversely correlated with BDI score (r = -0.35; P = 0.008) and was positively correlated with QOL score (r = 0.38; P = 0.011). A low level of PA was inversely correlated with SSAS score (r = -0.39; P < 0.001). In healthy controls, a high level of PA was positively correlated with QOL score (r = 0.50; P = 0.043). Moderate PA level was inversely correlated with SSAS score (r = -0.59; P < 0.001). A low level of PA was also positively correlated with BDI score (r = 0.35; P = 0.008). A moderate or low intensity of PA was inversely correlated with depression and somatosensory amplification and was positively correlated with QOL in breast cancer patients. Finally, we suggest that progressively low-to-moderate levels of PA can be well adapted to positively impact several measures of mental health.

Cross-cultural comparison of breast cancer patients' Quality of Life in the Netherlands and Japan

Purpose

Cultural differences are hypothesized to influence patients’ Quality of Life (QoL) reports. However, there is a lack of empirical cross-cultural studies comparing QoL of patients with cancer. This study aims to compare QoL of women with breast cancer in the Netherlands and Japan, and to investigate the association of QoL with sociodemographic, clinical, and psychological variables (illness perceptions).

Methods

Dutch (n = 116) and Japanese (n = 148) women with early breast cancer undergoing chemotherapy completed the EORTC QLQ-C30 and Brief Illness Perception Questionnaire immediately before their second cycle of chemotherapy.

Results

Dutch women reported poorer Physical, Role, Emotional, and Cognitive functioning than Japanese women. Additionally, illness perceptions were significantly different in Japan and the Netherlands, but these did not vary across treatment type. In Japan, QoL of women receiving AC-chemotherapy was better than that of women receiving FEC-chemotherapy, whereas in the Netherlands, QoL did not vary as a function of chemotherapy. Illness perceptions about symptom severity, adverse consequences, and emotional representations were negatively related to most domains of patients’ QoL in both countries. Adding illness perceptions as covariates to the ANOVA analyses rendered the effects of country and treatment type on QoL non-significant.

Conclusions

Comparing Dutch and Japanese women with early breast cancer revealed important differences in treatment modalities and illness perceptions which both appear to influence QoL. Perceptions about cancer have been found to vary across cultures, and our study suggests that these perceptions should be considered when performing cross-cultural studies focusing on patient-reported outcomes.

Perceived distress and its association with depression and anxiety in breast cancer patients

Background

Breast cancer patients often experience a high level of distress. Psychological distress is a broad construct encompass both depression and anxiety. Previous studies in examining which of these psychological symptoms (either anxiety or depression) were more significantly associated with the distress level in breast cancer patients is lacking. This study aims to compare the level of depression and anxiety between patients with different level of distress. The correlation between the changes in distress level with depression or anxiety over 12 months was also examined.

Methods

This study is from the MyBCC cohort study. Two hundred and twenty one female breast cancer patients were included into the study. They were assessed at the time of diagnosis, 6 months and 12 month using Hospital Anxiety and Depression Scale (HADS) and distress thermometer. The information on age, ethnicity, treatment types and staging of cancer were collected.

Results

50.2%, 51.6% and 40.3% of patients had perceived high level of distress at baseline, 6 months and 1 year after diagnosis. Those with high perceived level of distress had significant higher anxiety scores even after adjusted for the underlying depressive scores (Adjusted OR at baseline = 1.28, 95% CI = 1.13–1.44; adjusted OR at 6 months = 1.27, 95% CI = 1.11–1.45; adjusted OR at 12 months = 1.51, 95% CI = 1.29–1.76). There were no significant differences in the depressive scores between the subjects with either low or high distress level. There was reduction in perceived level of distress, anxiety and depression scores at 12 months after the diagnosis. The decrease of distress was positively correlated with the reduction of anxiety scores but not the changes of depressive scores (r’ = 0.25).

Conclusion

Anxiety is a more significant psychological state that contributed to the feeling of distress in breast cancer as compared with depression. Levels of anxiety at diagnosis in this study would justify screening for anxiety, early identification and therapy for maintaining the psychological well-being of breast cancer patients. Further studies will be needed to measure the effectiveness of therapeutic interventions.

A prospective study of changes in anxiety, depression, and problems in living during chemotherapy treatments: effects of age and gender

PURPOSE

Monitoring distress assessment in cancer patients during the treatment phase is a component of good quality care practice. Yet, there is a dearth of prospective studies examining distress. In an attempt to begin filling this gap and inform clinical practice, we conducted a prospective, longitudinal study examining changes in distress (anxiety, depression, and problems in living) by age and gender and the roles of age and gender in predicting distress.

METHODS

Newly diagnosed Brazilian cancer patients (N = 548) were assessed at three time points during chemotherapy. Age and gender were identified on the first day of chemotherapy (T1); anxiety, depression, and problems in living were self-reported at T1, the planned midway point (T2), and the last day of chemotherapy (T3).

RESULTS

At T1, 37 and 17% of patients reported clinically significant levels of anxiety and depression, respectively. At T3, the prevalence was reduced to 4.6% for anxiety and 5.1% for depression (p < .001). Patients 40-55 years, across all time points, reported greater anxiety and practical problems than patients >70 years (p < .03). Female patients reported greater emotional, physical, and family problems than their male counterparts (p < .04).

CONCLUSIONS

For most patients, elevated levels of distress noted in the beginning of treatment subsided by the time of treatment completion. However, middle-aged and female patients continued to report heightened distress. Evidence-based psychosocial intervention offered to at risk patients during early phases of the treatment may provide distress relief and improve outcomes over the illness trajectory while preventing psychosocial and physical morbidity due to untreated chronic distress.

Predicting general and cancer-related distress in women with newly diagnosed breast cancer

BACKGROUND

Psychological distress can impact medical outcomes such as recovery from surgery and experience of side effects during treatment. Identifying the factors that explain variability in distress would guide future interventions aimed at decreasing distress. Two factors that have been implicated in distress are illness perceptions and coping, and are part of the Self-Regulatory Model of Illness Behaviour (SRM). The model suggests that coping mediates the relationship between illness perceptions and distress. Despite this; very little research has assessed this relationship with cancer-related distress, and none have examined women with screen-detected breast cancer. This study is the first to examine the relative contribution of illness perceptions and coping on general and cancer-related distress in women with screen-detected breast cancer.

METHODS

Women recently diagnosed with breast cancer (N = 94) who had yet to receive treatment completed measures of illness perceptions (Revised Illness Perception Questionnaire), cancer-specific coping (Mental Adjustment to Cancer Scale), general anxiety and depression (Hospital Anxiety and Depression scale), and cancer-related distress.

RESULTS

Hierarchical regression analyses revealed that medical variables, illness perceptions and coping predicted 50% of the variance in depression, 42% in general anxiety, and 40% in cancer-related distress. Believing in more emotional causes to breast cancer (β = .22, p = .021), more illness identity (β = .25, p = .004), greater anxious preoccupation (β = .23, p = .030), and less fighting spirit (β = -.31, p = .001) predicted greater depression. Greater illness coherence predicted less cancer-related distress (β = -.20, p = .043). Greater anxious preoccupation also led to greater general anxiety (β = .44, p < .001) and cancer-related distress (β = .37, p = .001). Mediation analyses revealed that holding greater beliefs in a chronic timeline, more severe consequences, greater illness identity and less illness coherence increases cancer-specific distress (ps < .001) only if women were also more anxiously preoccupied with their diagnosis.

CONCLUSIONS

Screening women for anxious preoccupation may help identify women with screen-detected breast cancer at risk of experiencing high levels of cancer-related distress; whilst illness perceptions and coping could be targeted for use in future interventions to reduce distress.

Illness representations, coping, and illness outcomes in people with cancer: a systematic review and meta-analysis

OBJECTIVE

Cancer is associated with negative health and emotional outcomes in those affected by it, suggesting the need to better understand the psychosocial determinants of illness outcomes and coping. The common sense model is the leading psychological model of self-regulation in the face of illness and assumes that subjective illness representations explain how people attempt to cope with illness. This systematic review and meta-analysis examines the associations of the common sense model's illness representation dimensions with health and coping outcomes in people with cancer.

METHODS

A systematic literature search located 54 studies fulfilling the inclusion criteria, with 38 providing sufficient data for meta-analysis. A narrative review of the remaining studies was also conducted.

RESULTS

Random-effects models revealed small to moderate effect sizes (Fisher Z) for the relations between illness representations and coping behaviors (in particular between control perceptions, problem-focused coping, and cognitive reappraisal) and moderate to large effect sizes between illness representations and illness outcomes (in particular between identity, consequences, emotional representations, and psychological distress). The narrative review of studies with insufficient data provided similar results.

CONCLUSIONS

The results indicate how illness representations relate to illness outcomes in people with cancer. However, more high-quality studies are needed to examine causal effects of illness representations on coping and outcomes. High heterogeneity indicates potential moderators of the relationships between illness representations and health and coping outcomes, including diagnostic, prognostic, and treatment-related variables. This review can inform the design of interventions to improve coping strategies and mental health outcomes in people with cancer.

Psychological adjustment after breast cancer: a systematic review of longitudinal studies

OBJECTIVES

Breast cancer (BC) can be a traumatic and stressful experience for women, but there are wide-ranging differences in the ways in which women respond and adapt to BC. This systematic review examines which sociodemographic, disease-related, and psychosocial factors near diagnosis predict later psychological adjustment to BC.

METHODS

Database searches were conducted in 9 different health-related databases from 2000 to December 2015 using relevant search terms. Full-text, peer-reviewed articles in English that analyzed potential predictors of psychological adjustment in longitudinal studies were considered for inclusion.

RESULTS

Of 1780 abstracts, 41 studies fulfilled inclusion criteria. Consistent sociodemographic and disease-related variable predictors of adjustment were income, fatigue, cancer stage, and physical functioning. Psychosocial factors, particularly optimism and trait anxiety, as well as perceived social support, coping strategies, and initial levels of psychological functioning, were found to be predictive of later depressive and anxiety symptoms, psychological distress, and quality of life for women with BC, in predictable ways. Other psychosocial variables, such as cognitive and body image factors, predicted psychological adjustment but were explored only by a few studies.

CONCLUSIONS

The majority of studies showed a significant relationship between psychosocial factors and psychological adjustment. These results point to specific sociodemographic, disease-related, and psychosocial factors that can help to identify women at the time of diagnosis who are at risk for long-term psychological challenges so they can be referred for psychological support that targets their specific needs and can improve their quality of life and mood and decrease indicators of anxiety, depression, and psychological distress.

The relationship between illness representations, risk perception and fear of cancer recurrence in breast cancer survivors

OBJECTIVE

Fear of cancer recurrence, although distinct from distress continues to be under-evaluated, captured, or treated when standard distress scales are used to assess concerns of cancer survivors. We tested a model assessing the association of demographic and clinical factors, illness representations, and perceived risk with fear of cancer recurrence in breast cancer survivors.

METHODS

We recruited 117 breast cancer survivors at least one year after completing breast cancer treatment from Internet discussion boards for this cross-sectional, descriptive, correlational study. Participants completed a survey that assessed their level of fear of cancer recurrence as well as their illness representations, perceived risk of recurrence, and demographic and medical characteristics.

RESULTS

Our model explained 62% of the variance in fear of cancer recurrence. Emotional representations (β = .46, p < .01), symptom attribution (β = .21, p < .01), timeline (β = .23, p < .01), and consequences (β = .16, p < .03) were significantly related to fear of recurrence. By contrast, the majority of clinical and demographic variables were not significant contributors to fear of recurrence.

CONCLUSIONS

Upon completion of cancer treatment, survivors with more emotional representations of the experience and those who attribute unrelated symptoms to their breast cancer have a higher level of fear of recurrence. Evaluation of these factors during treatment may help mitigate fear of recurrence in the survivorship phase of the breast cancer trajectory. Copyright © 2016 John Wiley & Sons, Ltd.

Depressive symptom trajectories in women affected by breast cancer and their male partners: a nationwide prospective cohort study

PURPOSE

The purpose of this study was to identify subgroups of breast cancer patients and their partners based on distinct trajectories of depressive symptoms, to examine how relationship quality and medical and sociodemographic factors were associated with these trajectories, and to explore whether patients and partners had similar trajectories.

METHODS

A nationwide, population-based cohort of couples dealing with breast cancer was established in Denmark. Participants completed the Center for Epidemiologic Studies-Depression Scale at baseline and 5 and 12 months later. Sociodemographic and medical characteristics were retrieved from registers. A trajectory finite mixture model was used to identify trajectories.

RESULTS

The trajectories of depressive symptoms over time were analyzed in 546 patients and 508 partners. Among patients, 13 % had a high stable trajectory, 38 % an intermediate decreasing trajectory, and 49 % a low trajectory. Similar trajectories were found for partners (11, 22, and 67 %, respectively). Compared to the low trajectory, trajectories with higher depressive symptoms were associated with poorer relationship quality and previous use of antidepressants for patients and partners and with younger age, comorbidity, basic education, and chemotherapy for patients. The trajectories of patients and their partners were weakly correlated.

CONCLUSIONS

A considerable minority of patients and partners had a persistently high level of depressive symptoms. Poorer relationship quality and previous antidepressant use most consistently characterized patients and partners with higher depressive symptom trajectories.

IMPLICATIONS FOR CANCER SURVIVORS

In clinical practice, attention to differences in depressive symptom trajectories is important to identify and target patients and partners who might need support.

Predictors of initial levels and trajectories of anxiety in women before and for 6 months after breast cancer surgery

BACKGROUND

The diagnosis of breast cancer, in combination with the anticipation of surgery, evokes fear, uncertainty, and anxiety in most women.

OBJECTIVE

Study purposes were to examine in patients who underwent breast cancer surgery how ratings of state anxiety changed from the time of the preoperative assessment to 6 months after surgery and to investigate whether specific demographic, clinical, symptom, and psychosocial adjustment characteristics predicted the preoperative levels of state anxiety and/or characteristics of the trajectories of state anxiety.

INTERVENTIONS/METHODS

Patients (n = 396) were enrolled preoperatively and completed the Spielberger State Anxiety inventory monthly for 6 months. Using hierarchical linear modeling, demographic, clinical, symptom, and psychosocial adjustment characteristics were evaluated as predictors of initial levels and trajectories of state anxiety.

RESULTS

Patients experienced moderate levels of anxiety before surgery. Higher levels of depressive symptoms and uncertainty about the future, as well as lower levels of life satisfaction, less sense of control, and greater difficulty coping, predicted higher preoperative levels of state anxiety. Higher preoperative state anxiety, poorer physical health, decreased sense of control, and more feelings of isolation predicted higher state anxiety scores over time.

CONCLUSIONS

Moderate levels of anxiety persist in women for 6 months after breast cancer surgery.

IMPLICATIONS FOR PRACTICE

Clinicians need to implement systematic assessments of anxiety to identify high-risk women who warrant more targeted interventions. In addition, ongoing follow-up is needed to prevent adverse postoperative outcomes and to support women to return to their preoperative levels of function.

Trajectories of Anxiety Among Women with Breast Cancer: A Proxy for Adjustment from Acute to Transitional Survivorship

Anxiety is one of the main components of distress among women with breast cancer (BC), particularly in the early stages of the disease. Changes in anxiety over time may reflect the process of adjustment or lack thereof. The process of adjustment in the traverse of acute to transitional stages of survivorship warrants further examination. To examine the trajectory of anxiety and the specific patterns that may indicate a lack of adjustment within 2 years following BC surgery, survey data from a 2-year prospective cohort study of 725 women with BC were analyzed by Mixture Growth Modelling and logistic regression and Analysis of Variance. A piece-wise growth curve displayed the best fit to the data, indicating a significant decrease in anxiety in the first year, followed by a slower rate of change during the second year. Four classes of trajectories were identified: High Stable, High Decrease, Mild Decrease, and Low Decrease. Of these, High Stable anxiety showed the most substantive indications of lack of adjustment. This subgroup was predominantly characterized by sociodemographic variables such as financial difficulties. Our results support an emphasis on the transitional nature of the stage that follows the end of primary active treatment and imply a need for supportive follow up care for those who display lack of adjustment at this stage.

Co-occurrence of anxiety and depressive symptoms following breast cancer surgery and its impact on quality of life

PURPOSE

Little is known about the prevalence of combined anxiety and depressive symptoms (CADS) in breast cancer patients. Purpose was to evaluate for differences in demographic and clinical characteristics and quality of life (QOL) prior to breast cancer surgery among women classified into one of four distinct anxiety and/or depressive symptom groups.

METHODS

A total of 335 patients completed measures of anxiety and depressive symptoms and QOL prior to and for 6 months following breast cancer surgery. Growth Mixture Modelling (GMM) was used to identify subgroups of women with distinct trajectories of anxiety and depressive symptoms. These results were used to create four distinct anxiety and/or depressive symptom groups. Differences in demographic, clinical, and symptom characteristics, among these groups were evaluated using analyses of variance and Chi square analyses.

RESULTS

A total of 44.5% of patients were categorized with CADS. Women with CADS were younger, non-white, had lower performance status, received neoadjuvant or adjuvant chemotherapy, had greater difficulty dealing with their disease and treatment, and reported less support from others to meet their needs. These women had lower physical, psychological, social well-being, and total QOL scores. Higher levels of anxiety with or without subsyndromal depressive symptoms were associated with increased fears of recurrence, hopelessness, uncertainty, loss of control, and a decrease in life satisfaction.

CONCLUSIONS

Findings suggest that CADS occurs in a high percentage of women following breast cancer surgery and results in a poorer QOL. Assessments of anxiety and depressive symptoms are warranted prior to surgery for breast cancer.

Illness representation and sense of coherence in dementia caregiving

The objectives of this study were to describe illness representations in dementia caregiving and examine the relationship between illness perceptions and carers’ sense of coherence. Illness perceptions were assessed by the Brief Illness Perception Questionnaire. We measured sense of coherence, symptoms of anxiety and depression and carer burden. Regression analyses indicated that after controlling for demographic factors, burden and psychological distress in carers, illness coherence and emotional responses to the disease independently contributed towards explaining variance in carers’ sense of coherence. Results provide support for the usefulness of the self-regulation model in understanding dementia caregiving.

Trajectories of depressive symptoms following breast cancer diagnosis

BACKGROUND

This longitudinal study sought to identify groups of breast cancer survivors exhibiting distinct trajectories of depressive symptoms up to 24 months following diagnosis, and to describe characteristics associated with these trajectories.

METHODS

A total of 653 women completed baseline questionnaires within 8 months of breast cancer diagnosis on patient characteristics, symptoms, and psychosocial variables. Depressive symptoms were assessed at baseline and 6, 12, and 18 months after baseline. Chart reviews provided cancer and treatment-related data. Finite mixture modeling identified trajectories of depressive symptoms measured with the Beck Depression Inventory (BDI).

RESULTS

Six distinct trajectories were identified. Just over half of the sample had consistently very low (3.8%) or low (47.3%) BDI scores well below the traditional BDI cutoff point of 10 thought to be indicative of clinically significant depression; 29.2% had consistently borderline scores; 11.3% had initially high scores that declined over time, but remained above the cutoff point; 7.2% showed increased BDI over time; and a small but unique group (1.1%) reported chronically high scores above 25. Women in groups with lower depressive symptom levels were older, had less rigorous chemotherapy, fewer physical symptoms (fatigue and pain), and lower levels of illness intrusiveness.

CONCLUSIONS

Approximately 20% of women had levels of depressive symptoms indicative of clinical depression that were maintained 2 years postdiagnosis. Factors related to trajectory membership such as illness intrusiveness, social support, fatigue, pain, and vasomotor symptoms suggest targets for possible intervention.

IMPACT

Results demonstrate the heterogeneity of depressive symptoms following breast cancer and the need for continued screening posttreatment.

Illness representations and psychological adjustment of Greek couples dealing with a recently-diagnosed cancer: dyadic, interaction and perception-dissimilarity effects

The aim was to examine the impact of the dyadic, interaction and dissimilarity effects of the illness representations on the psychological health of recently diagnosed cancer patients and spouses in Greece. The sample consisted of 298 individuals nested in 149 couples. Effects were examined with the Actor-Partner Interdependence Model. Both actor (i.e., within person) and partner (i.e., between partners) effects were detected for both patients' and spouses' psychological symptoms. The negative association of patients' psychological symptoms with their representations of illness coherence was weak at the higher and medium levels, and stronger at the lower levels of spouse corresponding representations. Patient-partner discrepancy in perceived illness consequences was associated with more psychological symptoms in patients. Adaptation to cancer is a dyadic process within the context of which patient and partner psychological well-being is affected by each other's understanding of illness. Thus, the parallel examination of the illness representations of both partners is needed from the early phases of the illness trajectory.

Indicators of distress in newly diagnosed breast cancer patients

Background. The diagnosis, treatment, and long-term management of cancer can present individuals with a multitude of stressors at various points in that trajectory. Psychosocial distress may appear early in the diagnostic process and have negative effects on compliance with treatment and subsequent quality of life.

Purpose. The aim of the study was to determine early-phase predictors of distress before any medical treatment.

Method. Consistent with the goals of the study, 123 newly diagnosed breast cancer patients (20 to 74 years old) completed multiple indicators of knowledge about breast cancer management and treatment, attitudes toward cancer, social support, coping efficacy, and distress.

Results. SEM analysis confirmed the hypothesized model. Age was negatively associated with the patient’s knowledge (β = − 0.22), which, in turn, was positively associated with both attitudes toward breast cancer (β = 0.39) and coping self-efficacy (β = 0.36). Self-efficacy was then directly related to psychological distress (β = − 0.68).

Conclusions. These findings establish indicators of distress in patients early in the cancer trajectory. From a practical perspective, our results have implications for screening for distress and for the development of early interventions that may be followed by healthcare professionals to reduce psychological distress.

Coping Strategies of Southern Italian Women Predict Distress Following Breast Cancer Surgery

The present study was aimed at investigating the role of coping strategies in predicting emotional distress following breast cancer, over and above the illness severity, operationalized in terms of the type of surgery performed. In order to achieve this goal, two groups of newly diagnosed breast cancer women were selected and compared on the basis of the type of surgical treatment received. A subsample of 30 women with quadrantectomy and sentinel lymph-node biopsy (SLNB) and a subsample of 31 patients with mastectomy and axillary dissection (MAD) filled in the Brief Cope scale and Hospital Anxiety and Depression Scale. Summarizing, results showed that emotional support, venting, and humor explained a statistically significant increment of variance in psychological distress indices. Implication for clinical practice and future research were discussed.

Psychological interventions for women with non-metastatic breast cancer

BACKGROUND

Breast cancer is the most common cancer affecting women worldwide. It is a distressing diagnosis and, as a result, considerable research has examined the psychological sequelae of being diagnosed and treated for breast cancer. Breast cancer is associated with increased rates of depression and anxiety and reduced quality of life. As a consequence, multiple studies have explored the impact of psychological interventions on the psychological distress experienced after a diagnosis of breast cancer.

OBJECTIVES

To assess the effects of psychological interventions on psychological morbidities, quality of life and survival among women with non-metastatic breast cancer.

SEARCH METHODS

We searched the following databases up to 16 May 2013: the Cochrane Breast Cancer Group Specialised Register, CENTRAL, MEDLINE, EMBASE, CINAHL and PsycINFO; and reference lists of articles. We also searched the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) search portal and ClinicalTrials.gov for ongoing trials in addition to handsearching.

SELECTION CRITERIA

Randomised controlled trials that assessed the effectiveness of psychological interventions for non-metastatic breast cancer in women.

DATA COLLECTION AND ANALYSIS

Two review authors independently appraised and extracted data from eligible trials. Any disagreement was resolved by discussion. Extracted data included information about participants, methods, the intervention and outcome.

MAIN RESULTS

Twenty-eight randomised controlled trials comprising 3940 participants were included. The most frequent reasons for exclusion were non-randomised trials and the inclusion of women with metastatic disease. A wide range of interventions were evaluated, with 24 trials investigating a cognitive behavioural therapy and four trials investigating psychotherapy compared to control. Pooled standardised mean differences (SMD) from baseline indicated less depression (SMD -1.01, 95% confidence interval (CI) -1.83 to -0.18; P = 0.02; 7 studies, 637 participants, I(2) = 95%, low quality evidence), anxiety (SMD -0.48, 95% CI -0.76 to -0.21; P = 0.0006; 8 studies, 776 participants, I(2) = 64%, low quality evidence) and mood disturbance (SMD -0.28, 95% CI -0.43 to -0.13; P = 0.0003; 8 studies, 1536 participants, I(2) = 47%, moderate quality evidence) for the cognitive behavioural therapy group than the control group. For quality of life, only an individually-delivered cognitive behavioural intervention showed significantly better quality of life than the control with an SMD of 0.65 (95% CI 0.07 to 1.23; P = 0.03; 3 studies, 141 participants, I(2) = 41%, very low quality evidence). Pooled data from two group-delivered studies showed a non-significant overall survival benefit favouring cognitive behavioural therapy compared to control (pooled hazard ratio (HR) 0.76, 95% CI 0.25 to 2.32; P = 0.63; 530 participants, I(2) = 84%, low quality evidence). Four studies compared psychotherapy to control with one to two studies reporting on each outcome. The four studies were assessed as high risk of bias and provided limited evidence of the efficacy of psychotherapy. Adverse events were not reported in any of the included studies.

AUTHORS' CONCLUSIONS

A psychological intervention, namely cognitive behavioural therapy, produced favourable effects on some psychological outcomes, in particular anxiety, depression and mood disturbance. However, the evidence for survival improvement is still lacking. These findings are open to criticism because of the notable heterogeneity across the included studies and the shortcomings of the included studies.

Illness perceptions within 6 months of cancer diagnosis are an independent prospective predictor of health-related quality of life 15 months post-diagnosis

OBJECTIVE

Studies have found that illness perceptions explain significant variance in health outcomes in numerous diseases. However, most of the research is cross-sectional and non-oncological. We examined, for the first time in breast, colorectal and prostate cancer patients, if cognitive and emotional illness perceptions near diagnosis predict future multidimensional health-related quality of life (HRQoL).

METHODS

UK-based patients (N = 334) completed the illness perception questionnaire-revised within 6 months post-diagnosis and the quality of life in adult cancer survivors scale 15 months post-diagnosis. Sociodemographic and clinical data were obtained from medical records. Hierarchical multiple regression analyses were conducted.

RESULTS

The sociodemographic and clinical factors collectively significantly predicted 8/12 HRQoL domains, although for 5/8 accounted for <10% of the variance. For all 12 HRQoL domains, illness perceptions collectively explained significant substantial additional variance (∆R(2) range: 5.6-27.9%), and a single illness perception questionnaire-revised dimension was the best individual predictor of 9/12 HRQoL domains. The consequences dimension independently predicted 7/12 HRQoL domains; patients who believed their cancer would have a more serious negative impact on their life reported poorer future HRQoL. The emotional representations and identity dimensions also predicted multiple HRQoL domains.

CONCLUSIONS

Future research should focus on realising the potential of illness perceptions as a modifiable target for and mediating mechanism of interventions to improve patients' HRQoL.

Trajectories of distress, anxiety, and depression among women with breast cancer: Looking beyond the mean

OBJECTIVE

Little is known about the development of psychological wellbeing over time among women who have been treated for breast cancer. The aim of this study was to identify distinct patterns of distress, anxiety, and depression in such women.

METHODS

We invited 426 consecutive women with newly diagnosed primary breast cancer to participate in this study, and 323 (76%) provided information on distress ('distress thermometer') and on symptoms of anxiety and depression ('hospital anxiety and depression scale'). Semiparametric group-based mixture modeling was used to identify distinct trajectories of distress, anxiety, and depressive symptoms assessed the week before surgery and four and eight months later. Logistic regression analysis was used to evaluate the characteristics of women in the distinct groups.

RESULTS

Although no sub-group of women with chronic severe anxiety or depressive symptoms was found, we did identify a sub-group of 8% of the women who experienced continuously severe distress. Young age, having a partner, shorter education, and receiving chemotherapy but not radiotherapy might characterize women whose psychological symptoms remain strong eight months after diagnosis.

CONCLUSION

By looking beyond the mean, we found that 8% of the women experienced chronic severe distress; no sub-groups with chronic severe anxiety or depression were identified. Several socio-demographic and treatment factors characterized the women whose distress level remained severe eight months after diagnosis. The results suggest that support could be focused on relatively small groups of patients most in need.

The association of metacognitive beliefs with emotional distress after diagnosis of cancer

OBJECTIVE

Emotional distress after a diagnosis of cancer is normal and, for most people, will diminish over time. However, a significant minority of patients with cancer experience persistent or recurrent symptoms of emotional distress for which they need help. A model developed in mental health, the self-regulatory executive function model (S-REF), specifies that maladaptive metacognitive beliefs and processes, including persistent worry, are key to understanding why such emotional problems persist. This cross-sectional study explored, for the first, time whether metacognitive beliefs were associated with emotional distress in a cancer population, and whether this relationship was mediated by worry, as predicted by the S-REF model.

METHOD

Two hundred twenty-nine participants within 3 months of diagnosis of, and before treatment for, primary breast or prostate cancer completed self-report questionnaires measuring anxiety, depression, posttraumatic stress disorder (PTSD) symptoms, metacognitive beliefs, worry, and illness perceptions.

RESULTS

Regression analysis showed that metacognitive beliefs were associated with symptoms of anxiety, depression, and PTSD, and explained additional variance in these outcomes after controlling for age, gender, and illness perceptions. Structural equation modeling was consistent with cross-sectional hypotheses derived from the theory that metacognitive beliefs cause and maintain distress both directly and indirectly by driving worry.

CONCLUSIONS

The findings provide promising first evidence that the S-REF model may be usefully applied in cancer. Further study is required to establish the predictive and clinical utility of these findings.
