Negative illness perceptions are related to poorer health-related quality of life among thyroid cancer survivors: Results from the PROFILES registry

Illness perception profile among cancer patients and its influencing factors: A cross-sectional study

PURPOSE

The purpose of this study was to explore latent profiles of illness perception among cancer patients and its influencing factors.

METHODS

This study was a cross-sectional study adopting convenience sampling to select cancer patients from two hospitals in China. A total of 286 patients completed Brief Illness Perception Questionnaire, Post-traumatic Growth Inventory, Fear of Disease Progression Questionnaire and Psychosocial Adjustment to Illness Scale. Latent profile analysis and multiple linear regression were performed to explore the subgroups and factors influencing classification.

RESULTS

Three subgroups were identified, which were labelled as "Moderate Illness Perception Group" (16.8%; C1), "High Illness Perception with Heightened Concerns Group" (68.5%; C2) and "High Resilience and Low Symptomatic Impact Group" (14.7%; C3). Specifically, "Normal", "Mild symptom" and "Bed time during the day <50%" of "Functional Status" were more associated with C3. "Worker", "Farmer" and "Self-employed" were more associated with C1 and C2. Patients who had more "knowledge of the disease" were more associated with C2 and C3, who had less "post-traumatic growth" were more associated with C1, and who had less "fear of disease progression" and more "psychosocial adjustment" were more associated with C3 (all P < 0.05).

CONCLUSIONS

There was significant variability of illness perception among three subgroups of cancer patients, which emphasized the complexity of psychological condition. The insights derived from these distinct profiles enables tailored interventions and patient-centered communication strategies. However, integrating objective measures or biomarkers is needed to complement self-reported data.

Distress, illness perception and coping style among thyroid cancer patients after thyroidectomy: A cross-sectional study

PURPOSE

Thyroid cancer generally has a good prognosis, and thyroidectomy is the main treatment given to thyroid cancer patients. Almost every cancer patient experiences varying degrees of distress, which can reduce their quality of life. This study aims to explore the level of distress and its relationship with illness perception and coping style among Chinese thyroid cancer patients after thyroidectomy and to identify the influencing factors on distress.

METHODS

A cross-sectional study with convenience sampling method was conducted. Totally 184 thyroid cancer patients after thyroidectomy were recruited in a tertiary hospital in Southern China with the response rate being 94.4% . The participants were investigated by a self-designed demographic and disease-related questionnaire, the Distress Management, the Brief Illness Perception Questionnaire, and the Medical Coping Modes Questionnaire. Descriptive statistics, univariate analysis, and multivariate linear regression were applied for data analysis.

RESULTS

In total, 99 (53.8%) thyroid cancer patients after thyroidectomy scored 4 or higher on the DT. Illness perception, emotional problem, body image loss by surgical scars, and acceptance-resignation were the influencing factors of distress and could explain 67.6% of the variance of distress among thyroid cancer patients after thyroidectomy.

CONCLUSIONS

Healthcare professionals should not ignore the distress among thyroid cancer patients after thyroidectomy and should take effective measures to alleviate the distress of thyroid cancer patients after thyroidectomy by enhancing their accurate and positive illness perceptions, decreasing their emotional problems, alleviating their body image loss by surgical scars, and avoiding acceptance-resignation coping style.

Trajectories of illness perceptions in paediatric cancer patients and their parents and associations with health-related quality of life: Results of a prospective-longitudinal study

OBJECTIVE

In paediatric oncology, little is known about trajectories of illness perceptions and their longitudinal associations with health-related quality of life (HRQoL). Therefore, the aim of this study was to investigate changes in illness perceptions in children and parents over a one-year-period and to investigate predictive value of child's and parent's illness perceptions during acute treatment for child's HRQoL 1 year later.

METHODS

N = 65 child-parent-dyads participated in a longitudinal study (retention rate: 80.2%). Children were 4-18 years of age and underwent acute cancer treatment at baseline. Children and parents reported on their own illness perceptions (Illness-Perception-Questionnaire-Revised), as well as on the child's HRQoL (KINDL-R) at baseline and one-year-follow-up. Paired-samples t-tests were calculated to investigate changes over time. A hierarchical multiple regression analysis was performed to investigate predictive value of child's and parent's illness perceptions for child's HRQoL.

RESULTS

Child's HRQoL t(63) = -6.73, p < 0.001, their perceptions of coherence (i.e. understanding; t(54) = -2.36, p = 0.022) and consequences of their illness (t(54) = 2.86, p = 0.006), and parent's perception of cyclical trajectory (t(61) = 2.06, p = 0.044) improved from baseline to 1-year-follow-up. All other illness perceptions remained stable. Exploratory post-hoc analyses showed differences in the pattern of change in age-, gender-, and diagnosis-specific subgroups. After controlling for baseline levels of HRQoL, child's perceptions of symptoms and consequences were independent predictors of their HRQoL 1 year later (R2 = 0.396, F(2,52) = 10.782, p < 0.001), whereas no parent's illness perceptions added predictive value.

CONCLUSION

In paediatrics, child's and parent's illness perceptions should be assessed. Our findings highlight the importance of illness perceptions as potential modifiable variables in interventions to improve child's HRQoL.

The puppet interview to measure illness perceptions in paediatric oncology: development and psychometric properties in acute treatment and follow-up care

BACKGROUND

Illness perceptions comprise assumptions about symptoms, timeline, consequences, controllability, and emotional responses to an illness. Recent evidence shows that illness perceptions are associated with coping and well-being. So far, assessment in paediatric care was based on parental report only, since no instrument for the direct assessment of young children was available. We aim to describe the development (incl. indication and contraindication) of an innovative puppet interview to assess illness perceptions in children with cancer from the age of four years. Moreover, we investigate longitudinal trajectories and examine psychometric properties.

METHODS

The puppet interview was developed based on the Illness-Perception-Questionnaire-Revised and the Berkeley-Puppet-Interview. Longitudinal trajectories and psychometric properties were examined in a sample of patient-parent dyads (N = 75) in a prospective longitudinal study in acute treatment with a 1-year follow-up (study 1: nT1 = 41, nT2 = 27) and in a cross-sectional study in follow-up care (study 2, n = 34).

RESULTS

The puppet interview is comprehensible and well-received by children in acute treatment and follow-up care. There were significant differences in perceptions of a chronic timeline (U = 301.00, p = .008), consequences (U = 251.00, p = .008), and emotional representations (U = 244.50, p = .020) between children in acute treatment and children in follow-up care. Over the course of one year, children in acute treatment perceived more symptoms as part of their illness (MT1 = 3.6, SDT1 = 2.9, MT2 = 4.5, SDT2 = 3.1, n = 27, Z = -2.603, p = .009). We found expected intercorrelations between illness perception dimensions, e.g. between perception of consequences and emotional representations (rτ = .27, p = .033), and between perception of a chronic timeline and consequences (rτ = .38, p = .001). Moreover, we found confirming results regarding construct validity, as child's perceptions of symptoms correlated with their self-rated HRQoL (rτ = -.32, padj. = .014). Also parent-rated subscale on illness-specific aspects of child's HRQoL correlated with child's perception of symptoms (rτ = -.26, padj. = .016), cyclicity (rτ = -.28, padj. = .016), and consequences (rτ = -.34, padj. = .014). Acceptable internal consistency was shown for the dimensions timeline-acute/chronic and personal control.

CONCLUSIONS

Parental report can now be complemented by a self-report of illness perceptions in children aged four years and older. This will allow for the further adaptation of medical and psychosocial care during and after acute cancer treatment.

The "not so good" thyroid cancer: a scoping review on risk factors associated with anxiety, depression and quality of life

The incidence of thyroid cancer has increased in recent years, leading to a growing number of survivors facing lifelong consequences. This scoping review investigated anxiety, depression, and quality of life (QoL) in thyroid cancer survivors compared to the general population, those with benign pathology, and survivors of other types of cancers. Moreover, we aimed to identify the risk factors associated with anxiety, depression, and QoL in thyroid cancer patients. A total of 727 articles were identified through PubMed, ProQuest, Cochrane, and Google Scholar databases, and 68 articles that met the criteria were selected for data extraction. Thyroid cancer survivors have a poorer QoL compared to the general population, population with benign pathology, and survivors of other types of cancer associated with worse clinical outcomes. The main risk factors are grouped into socioeconomic factors, disease-specific factors, management factors, comorbidities, and patient perceptions. Effective communication between the patient and the medical team and behavioral interventions may reduce these risks. Despite the common perception of thyroid cancer as a "good cancer," the findings of this review demonstrate the need to address the risk factors associated with increased anxiety, depression, and lower QoL in survivors.

Illness perceptions, fear of progression and health-related quality of life during acute treatment and follow-up care in paediatric cancer patients and their parents: a cross-sectional study

BACKGROUND

This study examines the role of illness perceptions and fear of progression (FoP) in paediatric cancer patients and their parents for patient's health-related quality of life (HRQoL), controlling for sociodemographic and medical variables. 4-18-year-old patients in acute treatment or follow-up care and one parent were examined.

METHODS

N = 46 patient-parent dyads in acute treatment and n = 84 dyads in follow-up care completed measures on illness perceptions (Illness-Perceptions-Questionnaire for 12-18-year-old patients and parents or as age-adapted puppet interview for 4-11-year-old patients) and FoP (Fear-of-Progression-Questionnaire for 7-18-year-old patients and parents). Patients also completed the KINDL-R to measure HRQoL. Hierarchical multiple regression analyses were calculated.

RESULTS

In acute treatment, patient's perceptions of symptoms and cyclicity of their illness explained variation in their HRQoL in addition to sociodemographic and medical variables. In follow-up care, patient's FoP and parent's perception of consequences explained additional variation in patient's HRQoL. Overall, sociodemographic and medical variables explained less variation in HRQoL in follow-up care than in acute treatment.

CONCLUSIONS

Our results stress the importance of psychological factors for the well-being of paediatric cancer patients, particularly in follow-up care, where sociodemographic and medical variables play a lesser role. We recommend screening for illness perceptions and FoP during and after acute treatment to support patients and parents. Furthermore, standardized interventions focussed on changing maladaptive illness perceptions should be developed and evaluated. As parents' perceptions, thoughts, and feelings may also play an important role for the well-being of the patients, interventions should be family-focussed and include parents.

Global thyroid cancer incidence trend and age-period-cohort model analysis based on Global Burden of Disease Study from 1990 to 2019

Background

In view of the rapid increase in the incidence of thyroid cancer (TC) and the spread of overdiagnosis around the world, the quantitative evaluation of the effect of age, period and birth cohort on the incidence of TC, and the analysis of the role of different factors in the incidence trend can provide scientific basis and data support for the national health departments to formulate reasonable prevention and treatment policies.

Methods

The study collated the global burden disease study data of TC incidence from 1990 to 2019, and used APC model to analyze the contribution of age, period and birth cohort to the incidence trend of TC.

Results

There was an obvious unfavorable upward trend in terms of age and cohort effect all over the world. Since 2007, the growth rate of risk slowed down and the risk in female even decreased since 2012, which mainly contributed to the developed countries. In all SDI countries, 2002 is the dividing point of risk between male and female. In 2019, The global age-standardized incidence rate (ASIR) of TC in the 5 SDI countries all showed a significant upward trend, with the largest upward trend in the middle SDI countries.

Conclusion

The trend of rapid increase in the incidence of TC has begun to slow down, but the global incidence of TC has obvious gender and regional/national heterogeneity. Policy makers should tailor specific local strategies to the risk factors of each country to further reduce the burden of TC.

Measuring Clinical, Biological, and Behavioral Variables to Elucidate Trajectories of Patient (Reported) Outcomes: The PROFILES Registry

To take cancer survivorship research to the next level, it's important to gain insight in trajectories of changing patient (reported) outcomes and impaired recovery after cancer. This is needed as the number of survivors is increasing and a large proportion is confronted with changing health after treatment. Mechanistic research can facilitate the development of personalized risk-stratified follow-up care and tailored interventions to promote healthy cancer survivorship. We describe how these trajectories can be studied by taking the recently extended Dutch population-based PROFILES (Patient Reported Outcomes Following Initial treatment and Long term Evaluation of Survivorship) registry as an example. PROFILES combines longitudinal assessment of patient-reported outcomes with novel, ambulatory and objective measures (e.g., activity trackers; blood draws; hair samples; online food diaries; online cognitive tests; weighing scales; online symptoms assessment), and cancer registry and pharmacy databases. Furthermore, we discuss methods to optimize the use of a multidomain data collection like return of individual results to participants which may not only improve patient empowerment but also long-term cohort retention. Also, advanced statistical methods are needed to handle high-dimensional longitudinal data (with missing values) and provide insight into trajectories of changing patient (reported) outcomes after cancer. Our coded data can be used by academic researchers around the world. Registries like PROFILES, that go beyond boundaries of disciplines and institutions, will contribute to better predictions of who will experience changes and why. This is needed to prevent and mitigate long-term and late effects of cancer (treatment) and to identify new interventions to promote health.

"Dear hair loss"-illness perceptions of female patients with chemotherapy-induced alopecia

OBJECTIVE

Chemotherapy-induced alopecia (CIA) is one of the most common and distressing side effects of chemotherapy treatment. This study aims to assess the illness perceptions of female patients dealing with CIA, and their associations with demographic and clinical characteristics, coping strategies, and quality of life. The secondary aim was to compare the illness perceptions of patients with CIA with other samples, to help elucidate the specific perceptions of patients with CIA.

METHOD

Forty female patients at risk of severe hair loss due to chemotherapy treatment were included at the oncological daycare unit of a teaching hospital in the Netherlands. Patients were asked to complete the Brief-Illness Perception Questionnaire (B-IPQ) and the Hair Quality of Life (Hair-QoL) questionnaire.

RESULTS

Illness perceptions indicated that although patients understood their hair loss, they lacked being able to make sense of managing it, negatively impacting patients' lives. Psychological quality of life was significantly correlated with the B-IPQ domains: consequences, degree of concern, and emotional response. Social quality of life was significantly correlated with psychological quality of life. Patients with CIA felt significantly less able to manage their hair loss, compared to patients with breast cancer and psoriatic arthritis.

CONCLUSION

As patients' beliefs of being able to manage their hair loss are important for adopting and maintaining adequate coping behaviors, additional effort of health care providers in fostering patients' sense of control is indicated, focusing on patients' strengths during and after chemotherapy treatment. In the context of developing interventions for patients with CIA, consequences, concern, and emotional response are the major dimensions that should be taken in account to help patients deal with hair loss.

Machine learning-based random forest for predicting decreased quality of life in thyroid cancer patients after thyroidectomy

OBJECTIVE

Decreased quality of life (QoL) in thyroid cancer patients after thyroidectomy is a common, but there is a lack of predictive methods for decreased QoL. This study aimed to construct a machine learning-based random forest for predicting decreased QoL in thyroid cancer patients 3 months after thyroidectomy.

MATERIALS AND METHODS

Two hundred and eighty-six thyroid cancer patients after thyroidectomy were enrolled in this prospective cross-sectional study from November 2018 to June 2019, and were randomly assigned to training and validation cohorts at a ratio of 7:3. The European Organization for Research and Treatment of Cancer quality of life questionnaire version 3 (EORTC QLQ-C30) questionnaire was used to assess the QoL 3 months after thyroidectomy, and decreased QoL was defined as EORTC QLQ-C30 < 60 points. The random forest model was constructed for predicting decreased QoL in thyroid cancer patients after thyroidectomy.

RESULTS

The mean QoL 3 months after thyroidectomy was 65.93 ± 9.00 with 21.33% (61/286) decreased QoL. The main manifestation is fatigue in symptom scales and social functioning dysfunction in functional scales. The top seven most important indices affecting QoL were clinical stage, marital status, histological type, age, nerve injury symptom, economic income and surgery type. For random forest prediction model, the areas under the curve in the training and validation courts were 0.834 and 0.897, respectively.

CONCLUSION

The present study demonstrated that random forest model for predicting decreased QoL in thyroid cancer patients 3 months after thyroidectomy displayed relatively high accuracy. These findings should be applied clinically to optimise health care.

Relationship between illness perception, fear of progression and quality of life in interstitial lung disease patients: A cross-sectional study

AIMS AND OBJECTIVES

This study aimed to investigate whether fear of progression mediates the association between illness perception and quality of life among interstitial lung disease patients.

BACKGROUND

So far, the physiological treatment of interstitial lung disease is limited. In addition to immunosuppressants such as glucocorticoids, two anti-fibrosis drugs (pirfenidone and nintedanib) have shown moderately beneficial effects on slowing the progression of interstitial lung disease fibrosis. However, none of these drugs has shown reliable or strong beneficial effects on improving quality of life. Psychological care and mental health support strategies focusing on improving patients' quality of life are particularly important.

DESIGN

A cross-sectional study.

METHODS

A convenience sample of patients suffering from interstitial lung disease were enrolled from August to December 2019. Data including sociodemographic and clinical characteristics, illness perception, fear of progression and quality of life were collected. The descriptive analysis and Pearson correlations were analysed by SPSS 26.0 (IBM Corp.). PROCESS v3.4 (by Andrew F. Hayes) macro was applied to analyse the mediating effects. We used the STROBE checklist to report the results.

RESULTS

Both illness perception and fear of progression were correlated with quality of life. Fear of progression mediated the association between illness perception and quality of life. The indirect effect was 0.121, and the proportion of intermediary effect in the main effect was 26.36%.

CONCLUSION

Interstitial lung disease patients experience relatively poor quality of life and fear of progression exerts a mediating role between illness perception and quality of life.

RELEVANCE TO CLINICAL PRACTICE

This study alerts medical staff to pay attention to negative illness perception and excessive fear, which is helpful to formulate effective interventions to manage interstitial lung disease patients' quality of life.

Negative illness perceptions are related to poorer health-related quality of life among thyroid cancer survivors: Results from the PROFILES registry

BACKGROUND

Differentiated thyroid cancer (DTC) reports a poorer health-related quality of life (HRQoL) than a norm population. Patients' illness perceptions are modifiable and known associates of HRQoL in other cancers. The aim was to examine the relationship between illness perceptions and HRQoL among DTC survivors.

METHODS

DTC survivors registered in the Netherlands Cancer Registry diagnosed between 1990 and 2008, received a survey on illness perceptions (Brief-Illness Perception Questionnaire; B-IPQ) and HRQoL (European Organisation for Research and Treatment of Cancer, Quality of Life Questionnaire-Core 30; EORTC QLQ-C30). Multiple regression analyses were conducted investigating the relation between illness perceptions and HRQoL, while controlling for sociodemographic and clinical characteristics.

RESULTS

Two hundred and eighty-four DTC survivors were included. DTC survivors who believed their illness had many negative consequences; who perceived their illness as controllable by treatment; who had strong beliefs symptoms could be attributed to their illness; and who had strong beliefs their illness causes negative emotions, reported a poorer HRQoL.

CONCLUSIONS

Stronger negative illness perceptions are related to a poorer HRQoL among DTC survivors.
