Assessing factors associated with long-term work disability after cancer in Belgium: a population-based cohort study using competing risks analysis with a 7-year follow-up

Interventions for work participation of unemployed or work-disabled cancer survivors: a systematic review

Background: Supporting unemployed or work-disabled cancer survivors in their work participation can have extensive individual and societal benefits. We aimed to identify and summarise interventions for work participation of unemployed or work-disabled cancer survivors.Methods: Five databases (Medline, Embase, PsycINFO, CINAHL and Cochrane Library) were systematically searched for quantitative studies on interventions aimed at enhancing work participation of unemployed or work-disabled cancer survivors. Work participation refers to participation in the workforce, fulfilling one's work role. Manual and automatic screening (with ASReview software) were performed on titles and abstracts, followed by manual full-text screening. Data were extracted regarding study, patient and intervention characteristics, and work participation outcomes. Risk of bias (RoB) was assessed using the Cochrane RoB2 and QUIPS tools.Results: We identified 10,771 articles, of which we included two randomised controlled trials (RCTs), of which one feasibility RCT, and three cohort studies. In total, 1862 cancer survivors were included, with predominantly breast cancer. Work participation was mainly measured as time to return to work (RTW) and RTW rate. Interventions included components of coaching (e.g., psychological or rehabilitation), training (e.g., building confidence and managing fatigue) and self-management. Two RCTs with unclear RoB did not show an effect of multicomponent interventions compared to care as usual. One cohort study found a significant effect of a psycho-educational intervention on RTW rates, with moderate RoB. The other two cohort studies, with moderate RoB, reported significant associations between components including job search and placement assistance, and work participation.Discussion: Only few interventions aimed at enhancing work participation of unemployed or work-disabled cancer survivors, have been evaluated. In two cohort studies, promising components for future multicomponent interventions were identified. However, findings suggest that more evidence is necessary on such multicomponent interventions, in which elements explicitly directed at work and including the workplace should be included.

Return to work in head and neck cancer survivors: a systematic review

PURPOSE

Cancer survivors face higher rates of unemployment compared with individuals without a history of cancer. Compared to other cancer types, head and neck cancer (HNC) survivors face unique disease and treatment-specific issues that may limit return to work (RTW). This review aimed to determine employment outcomes of HNC survivors post-treatment and identify factors associated with RTW.

METHODS

A systematic search was conducted in MEDLINE, CINAHL and PsycINFO in December 2021. Inclusion criteria included adults (≥ 18 years); completed treatment for HNC; data available on RTW post-treatment. Both quantitative and qualitative studies were considered. Studies were critically appraised and data synthesised narratively.

RESULTS

Twenty-nine publications were included: 22 quantitative, four qualitative and three mixed methods. The proportion of HNC survivors who RTW ranged from 32 to 90%, with participants taking 3.6-11 months to RTW. Working in a professional role and having a supportive work environment were positively associated with RTW.

CONCLUSIONS

The proportion of HNC survivors who RTW varies significantly which may be due to the heterogeneity between the studies including difference in clinical characteristics of the participants and/or sample size. Future studies that are longitudinal, adequately powered and measure a range of clinical and demographic variables are needed to better understand the RTW experience and assist development of effective RTW strategies.

IMPLICATIONS FOR CANCER SURVIVORS

This review suggests potential areas for intervention, including enhanced symptom management and engaging with employers to foster supportive work environments to support RTW of HNC survivors.

Return to work of Italian cancer survivors: A focus on prognostic work-related factors

BACKGROUND: Return to work (RTW) enhances the general well-being and social participation of cancer survivors (CSs). OBJECTIVE: To describe the predictive value of work-related factors on the RTW process of CSs. The work accommodations, the perceived workload, and the barriers and facilitations of RTW are also reported. METHODS: This population-based cross-sectional survey was conducted in the Province of Reggio Emilia from July 2016 to July 2017. CSs who were 20–59 years old, first diagnosed with cancer, and employed at diagnosis were recruited. RESULTS: The majority of CSs (140/266, 53%) returned to work without difficulties, 42% reported difficulties, and 5% did not RTW. CSs who were shift workers (sex and age-adjusted Relative Risk [adj-RR] 1.30; 95% CI 0.94 –1.78) and who worked at night (adj-RR 1.36 95% CI 0.99 –1.86), in the evening (adj-RR 1.23; 95% CI 0.95 –1.57) and on Sundays (adj-RR 1.15; 95% CI 0.81 –1.63) perceived more difficulties. Physically demanding work and a long commute seemed to negatively impact RTW. Accommodations in work tasks (37%) or schedule (26%) were implemented. Workload was not acceptable for 18% of CSs. The main barriers concerned energy and drive functions, whereas remunerative employment was the foremost facilitation. CONCLUSIONS: Healthcare professionals should address work-related factors that might influence RTW with personalized interventions of vocational rehabilitation.

[Role of Clinical, Sociomedical and Psychological Factors on Return to Work of Patients with Breast Cancer 6 Months after Rehabilitation]

AIM OF THE STUDY

The majority of patients with non-metastatic breast cancer return to work after tumor therapy. A rate of up to 80% is given in national and international studies, which can vary considerably depending on the study population and the various social systems. However, it is unclear how many patients are reintegrated into work after medical rehabilitation and which clinical, sociodemographic and psychological factors play a role.

METHODS

In a multicentre study, clinical and sociodemographic data were collected from breast cancer patients at the beginning of their medical rehabilitation. Subjectively experienced deficits in attention performance (FEDA), depressive symptoms (PHQ-9) and health-related quality of life (EORTC QLQ-C30) were recorded using standardized questionnaires. The cognitive performance was also examined using a computer-based test battery (NeuroCog FX). A follow-up survey was carried out 6-9 months after medical rehabilitation. The subjective assessment of one's own cognitive performance (FEDA) was recorded again at this time.

RESULTS

396 of the originally 476 patients were included in the study. In the follow-up survey, 323/396 patients (82%) were again employed. In a regression model, sociodemographic factors proved to be particularly predictive with regard to occupational reintegration: employment at the time of the tumor diagnosis, job preserved after medical rehabilitation, employee status and gradual reintegration according to the Hamburg model (Nagelkerke R²=0.685). This model could not be improved by adding psychological variables. The subjective patient information in all questionnaires was highly correlated (r>0.57; p<0.001).

CONCLUSION

The vast majority of breast cancer patients return to work after medical rehabilitation. Socio-demographic factors play a crucial role in this. The regression model developed here, including the employment status, professional orientation and gradual reintegration, is of predictive importance and can be used in medical rehabilitation.

Returning to work in lung cancer survivors-a multi-center cross-sectional study in Germany

Purpose

To investigate the work situation of lung cancer survivors and to identify the factors associated with their returning to work.

Methods

Descriptive analysis and logistic regression were used to evaluate study population characteristics and independent factors of subsequently returning to work. To analyze time to return to work, Cox regression was used.

Results

The study sample included 232 lung cancer survivors of working age from 717 enrolled participants in the multi-center cross-sectional LARIS (Quality of Life and Psychosocial Rehabilitation in Lung Cancer Survivors) study. About 67% of the survivors were not employed during the survey. More than 51% of the survivors who were employed before their illness did not return to their work. The survivors who had returned to their careers were younger, associated with higher household income, lower fatigue score, and stable relationship and vocational training. Patients who received social service counseling showed a higher chance of regaining their career.

Conclusions

Lung cancer survivors were found to be associated with a high risk of unemployment and very low professional reintegration after interruption due to illness. More comprehensive studies are needed to support lung cancer survivors and targeting of patients in need of special attention in rehabilitation that would benefit from the findings in the present study.

Use of real-world data to study health services utilisation and comorbidities in long-term breast cancer survivors (the SURBCAN study): study protocol for a longitudinal population-based cohort study

INTRODUCTION

Breast cancer has become a chronic disease due to survival improvement and the need to monitor the side effects of treatment and the disease itself. The aim of the SURBCAN study is to describe comorbidity, healthcare services use and adherence to preventive recommendations in long-term breast cancer survivors and to compare them with those in women without this diagnosis in order to improve and adapt the care response to this group of survivors.

METHODS AND ANALYSIS

Population-based retrospective cohort study using real-world data from cancer registries and linked electronic medical records in five Spanish regions. Long-term breast cancer survivors diagnosed between 2000 and 2006 will be identified and matched by age and administrative health area with women without this diagnosis. Sociodemographic and clinical variables including comorbidities and variables on the use of health services between 2012 and 2016 will be obtained from databases in primary and hospital care. Health services use will be assessed through the annual number of visits to primary care professionals and to specialists and through annual imaging and laboratory tests. Factors associated with healthcare utilisation and comorbidities will be analysed using multilevel logistic regression models. Recruitment started in December 2018.

ETHICS AND DISSEMINATION

This study was approved by the Ethics Committee of Parc de Salut Mar. The results of the study will be published in a peer-reviewed journal and will be presented at national and international scientific conferences and at patient associations.

TRIAL REGISTRATION NUMBER

This protocol is registered in Clinical Trials.gov (identifier: NCT03846999).

Labor-force participation and working patterns among women and men who have survived cancer: A descriptive 9-year longitudinal cohort study

Aims:

Our aim was to investigate labor-force participation, working hours, job changes, and education over 9 years among persons who have survived more than 10 years after cancer, and compare it to controls.

Methods:

Register data on 2629 persons who survived cancer were stratified by gender and compared to data on 5258 matched controls. Persons who survived cancer were aged 30–50 when diagnosed with cancer and had a work contract prior to diagnosis. Descriptive analysis and t-tests were performed.

Results:

The proportion of female persons who survived cancer in the labor force was reduced from 100% to 83.9% during follow-up, demonstrating a significant difference compared to controls for each year measured. The proportion of male persons who survived cancer dropped from 100% to 84.8%, but was only significantly different compared to controls in 2 years. The proportion of female persons who had survived cancer who worked full-time was lower in all years compared to both controls and male persons who survived cancer; in turn, male persons who had survived cancer worked full-time less than male controls. The proportion of female persons who had survived cancer who worked less than 20 hours per week increased compared to controls. The frequency of change of employer was higher among female persons who survived cancer compared to controls for some years, but no significant differences between male persons who survived cancer and controls were found. Female persons who survived cancer were in education more often than male persons who survived cancer.

Conclusions:

Persons who survived cancer experienced reduced labor-force participation and working hours 9 years after diagnosis, and the reduction was more pronounced for women than for men. Working patterns were also different between genders and between persons who survived cancer and controls.

Psychosocial determinants predicting long-term sickness absence: a register-based cohort study

Background

This study assessed the psychosocial determinants as explanatory variables for the length of the work disability period. The aim was to estimate the predictive value of a selected set of psychosocial determinants from the Quickscan questionnaire for the length of the sick leave period. A comparison was also made with the most common biomedical determinant: diagnosis.

Methods

In a cohort study of 4 981 insured Belgian patients, the length of the sick leave was calculated using Kaplan–Meier. Predictive psychosocial determinants were selected using backward conditional selection in Cox regression and using concordance index values (C-index) we compared the predictive value of the biomedical to the psychosocial model in a sample subset.

Results

Fourteen psychosocial determinants were significantly (p<0.10) related to the length of the sick leave: health perception of the patient, physical workload, social support management, social support colleagues, work–health interference, psychological distress, fear of colleagues’ expectations, stressful life-events, autonomy, learning and development opportunities, job satisfaction, workload, work expectations and expectation to return to work. The C-index of this biopsychosocial model including gender, age and labour status was 0.80 (CI: 0.78; 0.81) (n=4 981). In the subset of 2 868 respondents with diagnostic information, the C-index for the same model was .73 (CI: 0.71; 0.76) compared with 0.63 (CI: 0.61; 0.65) for the biomedical model.

Conclusions

A set of 14 psychosocial determinants showed good predictive capacity (C-index: 0.80). Also, in a subset of the sample, the selected determinants performed better compared with diagnostic information to predict long-term sick leave (>6 months).

The changing relationship between health burden and work disability of Australian cancer survivors, 2003-2017: evidence from a longitudinal survey

BACKGROUND

The purpose of this study was to examine the relationship between the cancer health burden and themagnitude of work disability on cancer survivors in Australia from 2003 to 2017.

METHODS

A longitudinal prospective study design was undertaken among cancer patients using data from the Household, Income and Labour Dynamics in Australia survey. The longitudinal effect was captured using a fixed effect multinomial logistic regression model, which predicted changes in the relationship between cancer burden and work disability level controlling for socio-demographic, lifestyle and life conditions predictors.

RESULTS

The prevalence of long-term disability among cancer survivors was 50%, with 18% of patients experiencing extreme work disability. The magnitude of disability levels increased significantly with the level of health burden. Cancer survivors who faced a severe health burden were at 5.32 times significantly higher risk of having work disability compared with patients who had no health burden. Other potential predictors, such as older patients (relative risk ratio, RRR = 1.82; 95% CI: 1.57, 5.87), those engaged in lower levels of physical activities (RRR = 1.91; 95% CI: 1.07, 3.40), those who drink alcohol (RRR = 1.29; 95% CI: 1.15, 1.49), and poor socioeconomic status (RRR = 1.28; 95% CI: 1.16, 2.23) were all significantly associated with extreme work disability.

CONCLUSION

A substantial proportion of cancer survivors experienced work disability which was more pronounced with the magnitude of the cancer health burden. The different dimensions of disability might be prevented by introducing cancer survivor-specific evidence-based interventions, and incorporating comprehensive social support. Recommendations to improve public health policy aimed at reducing population-level unhealthy lifestyle behaviours include: using these findings to better outline the management of a sequelae course of treatment for cancer survivors; and identifying those who should undergo more intensive physical rehabilitation aimed at reducing their work disability level.

Long-Term Employment Outcomes among Female Cancer Survivors

Advances in early detection and treatment have led to a growing population of female cancer survivors, many of whom are of working age. We examined the relationship between cancer and long-term (>5 years) employment outcomes in a nationally representative sample of working-age women in the United States. Data from nine waves of the Health and Retirement Study were used to examine employment status and weekly hours worked among cancer survivors (n = 483) and women without cancer (n = 6605). We used random slope regression models to estimate the impact of cancer and occupation type on employment outcomes. There was no difference in employment status between cancer survivors and women without cancer at baseline; however, during follow-up, cancer survivors were more likely to be employed than women without cancer (odds ratio (OR) = 1.33, 95% confidence interval (CI): 1.11–1.58). Among 6–10-year survivors, professional workers were less likely (OR = 0.40, 95% CI: 0.21–0.74) to be employed than manual workers. Among >10-year survivors, professional workers averaged fewer weekly hours worked (−2.4 h, 95% CI: −4.4–−0.47) than manual workers. The impact of cancer on long-term employment outcomes may differ by occupation type. Identifying the occupation-specific mechanisms associated with the return to work will be critical to developing targeted strategies to promote employment in the growing female cancer survivor population.

Work adjustments and employment among breast cancer survivors: a French prospective study

PURPOSE

The objective of our study was to assess the rate of work adjustments 1 year after the diagnosis in a population of female breast cancer (BC) survivors, in the context of the French system of social protection. We also characterised these adjustments and their influence on the reduction of professional exclusion of patients 1 year after the diagnosis.

METHODS

This observational, prospective study was conducted from February 2015 to April 2016 among female patients with BC. Inclusion criteria were women aged between 18 and 65 years, treated for BC and integrated into the labour market at the time of diagnosis (working or on sick leave). Exclusion criteria were metastatic BC, retired patients and refusal to participate. A 1-year follow-up was scheduled, and data collection was performed with questionnaires.

RESULTS

In total, 213 patients were included between February 2015 and April 2016. One year after the diagnosis (T1), among 185 BC survivors, 78 (42.2%) patients were working. Among them, 13 patients did not interrupt their occupational activity and 65 returned to work after a period of sick leave. Sixty-four patients returned to work after the end of chemotherapy (after 6 months), and one returned to work before this therapeutic threshold. Sixty-six patients (35.7%) benefited from at least one adjustment of their work conditions to facilitate their return to work (RTW) or maintenance at work: working hours were decreased for 43 patients, and workstation changes were performed for 22 patients. An occupational health physician was involved for some patients; work adjustments were prescribed to 42 patients, 7 patients had medical restrictions for physical reasons and 4 patients had restrictions for psychological reasons. Forty-three patients benefited from part-time work prescribed for therapeutic reasons.

CONCLUSIONS

Referral to occupational health physicians and work adjustments remain limited in the process of RTW or maintenance at work after BC in France, despite their positive impact.

The EMPCAN study: protocol of a population-based cohort study on the evolution of the socio-economic position of workers with cancer

BACKGROUND

The improvements in cancer control led to an increase in the number of cancer survivors, notably, in the working age population (16-64 years). There is a strong need to assess and understand their reintegration on the labour market, which underlines and ensures their social integration and quality of life. The objectives of the EMPCAN study is therefore to measure the scale of return-to-work after cancer and to identify the determining factors, allowing for the implementation of an adequate socio-professional support.

METHODS

We requested data from the Belgian Cancer Registry and the Crossroad Bank for Social Security. We included all socially insured Belgian workers diagnosed between 2004 and 2011 with colorectal, breast, head & neck, prostate, testis, lung and corpus uteri cancer. The end of (administrative) follow-up was 31st December 2012. We include demographic, health-related and work-related factors in the analysis and observed how these factors interplay to determine the working status. After having solved legal, ethical and technical issues for the coupling, we will perform survival analysis with competing risks using the Fine and Gray model; we will also perform a multistate model using transitions probabilities; and finally, a group-based modeling for longitudinal data using the 'proc traj' package in SAS.

DISCUSSION

The results of the EMPCAN study will allow the provision of an evidence-based support to professional reintegration policies. It will also bring some key features for the prediction of the cancer-related social security needs. Besides the raise of awareness among health professionals and policy makers, this study could lead to a better planning and organization of vocational rehabilitation programs.
