Sickness Absence and Disability Pension After Breast Cancer Diagnosis: A 5-Year Nationwide Cohort Study

Future sick leave, disability pension, and unemployment among patients with cancer after returning to work: Swedish register-based matched prospective cohort study

INTRODUCTION

Despite increasing numbers of working-age cancer survivors, evidence on their future work-related circumstances is limited. This study examined their future sick leave, disability pension, and unemployment benefits compared to matched cancer-free individuals.

METHODS

A matched cohort study was conducted using nationwide Swedish registers. In total, 94,411 individuals aged 25 to 59 years when diagnosed with incident cancer in 2001-2012 and who returned to work after cancer were compared with their matched cancer-free individuals (N = 354,814). Follow-up started from the year before cancer diagnosis and continued up to 14 years. Generalized estimating equations were used to calculate incidence rate ratios (IRR) and odds ratios for the difference between cancer survivors and matched cancer-free individuals.

RESULTS

Compared with cancer-free individuals, cancer survivors had six times higher sick-leave days per year after cancer (IRR 6.25 [95% CI, 5.97-6.54] for men; IRR, 5.51 [5.39-5.64] for women). This higher number of sick-leave days declined over time but a two-fold difference persisted. An approximate 1.5 times higher risk of receiving disability pension remained during follow-up. The unemployment days tended to be lower for cancer survivors (IRR, 0.84 [0.75-0.94] for men; IRR, 0.91 [0.86-0.96] for women). Risk of sick leave and disability pension was higher among those with leukemia, colorectal, and breast cancer than skin and genitourinary cancers.

CONCLUSIONS

Cancer survivors who returned to work experienced a high and persisting sick leave and disability pension for over a decade. Prolonged receipt of a high amount of benefits may have long-term adverse impacts on financial circumstances; more knowledge to promote the environment that encourages returning to and remaining in work is needed.

Genetic variants and social benefit receipt in premenopausal women with breast cancer treated with docetaxel: a Danish population-based cohort study

PURPOSE

Breast cancer patients' need for social benefits may increase following taxane-based chemotherapy, due to long-lasting side effects. Specific single nucleotide polymorphisms (SNPs) may mediate such side effects. We investigated the association between SNPs related to taxane metabolism, transport, toxicity, or DNA and neural repair, and receipt of social benefits.

METHODS

From the Danish Breast Cancer Group, we identified premenopausal women diagnosed with stage I-III breast cancer during 2007-2011 and treated with docetaxel-based chemotherapy. We genotyped 21 SNPs from archived breast tumors using TaqMan assays. We ascertained social benefit payments from 1 year before to 5 years after diagnosis, using nationwide, administrative registry data. For each week, we categorized women as receiving health-related benefits (including sick leave and disability pension), labor market-related benefits (including unemployment benefits), or as being self-supporting. We computed rate ratios (RRs) of social benefit receipt for variant carriers (heterozygotes plus homozygotes) vs. non-carriers, using negative binominal regression with robust variance estimation.

RESULTS

Among 2430 women, 12% received health-related benefits before diagnosis, 80% at diagnosis, and ~ 24% 2 to 5 years after diagnosis. Labor market-related benefits were uncommon (3-6%). All RRs were near-null and/or imprecise.

CONCLUSION

We found no clinically meaningful impact of the selected SNPs on social benefit receipt among premenopausal breast cancer survivors treated with docetaxel.

Predictive factors for return to work among cancer survivors in Europe: A systematic review

Of the 4.4 million people diagnosed with cancer in Europe each year, around 36 % are of working age. Return-to-work rates vary across Europe. Work is important for the individual, as well as for society, and this review aims to provide an overview of the predictors for the return to work (RTW) process in European cancer survivors of working age. A systematic literature search was conducted. The present review included quantitative and qualitative study designs published since 2013. In total, the review included 85 papers examining cancer survivors with various cancer diagnoses in 18 European countries. Identified predictive factors for RTW related to the social system, treatment, disease, health behavior, the individuals' psychosocial, work, and sociodemographic situations. There is a need for a standardized definition and operationalization of RTW. Providers can use these results to identify survivors at risk and support cancer survivors in their RTW process.

Social characteristics and social benefit use among premenopausal breast cancer survivors in Denmark: a population-based cohort study

PURPOSE

In 2020, one million women aged < 55 years were diagnosed with breast cancer globally. The impact of breast cancer and its treatments on these women's ability to work and need for social benefits may differ by social characteristics. We evaluated social benefit use following breast cancer by education and cohabitation.

METHODS

We conducted a nationwide population-based cohort study, including women aged 18-55 years diagnosed with stage I-III breast cancer in Denmark during 2002-2011. Statistics Denmark provided information on cohabitation, education, and social benefit use from 1 year pre-diagnosis to 10 years post-diagnosis. We calculated weekly proportions of self-support, unemployment, disability pension, flexi jobs, and sick leave according to education and cohabitation.

RESULTS

Of 5345 women, 81.8% were self-supporting, 4.5% received disability pensions, 1.6% had flexi jobs, 3.6% were on sick leave, and 5.5% were unemployed 1 year pre-diagnosis. Ten years post-diagnosis, the proportions were 69.0%, 13.0%, 10.5%, 3.4%, and 2.0% of 3663 survivors. Disability pensions and flexi jobs increased from 12.1 to 26.4% and 2.8 to 13.5% in women with short education, from 4.1 to 12.8% and 1.8 to 12.2% in women with medium education, and from 0.8 to 6.0% and 0.9 to 6.9% in longer educated. Disability pensions increased more in women living alone (7.8 to 19.9%), than in cohabiting women (3.6 to 11.3%).

CONCLUSIONS

Use of social benefits reflecting lost ability to work was highest in less educated women and in women living alone.

IMPLICATIONS FOR CANCER SURVIVORS

Awareness of these groups is crucial when tailoring efforts to support work participation in cancer survivors.

Temporal trends in social security benefits for female breast cancer in Brazil

Abstract The aim of this study was to assess temporal trends in disability benefits for breast cancer awarded to women by Brazil’s National Social Security Institute. We conducted a time-series analysis of disability benefit incidence rates between 2007 and 2018 using joinpoint regression and data from the Unified Benefits Information System (SUIBE) and open access social security system database. The age-adjusted incidence rate increased by 6.7% per year between 2015 and 2018 after a period of stability between 2007 and 2014. The number of benefits granted to women aged 20-49 increased, on average, by 3.4% per year, showing a marked rise from 2015 to 2018 (10.4% per year). The findings highlight that breast cancer is an important cause of sick leave among female workers and that the incidence of the disease is growing in younger economically active women, reinforcing the importance of early referral to the Social Security Professional Rehabilitation Program to help workers return to work and readapt to working life.

Use of sickness benefits by patients with metastatic breast cancer-A Swedish cohort study

OBJECTIVE

The objective of this study is to determine the prevalence and predictors of sickness absence (SA) and disability pension (DP) in women with metastatic breast cancer (mBC).

METHODS

Data were obtained from Swedish registers concerning 1,240 adult women diagnosed 1997-2011 with mBC, from 1 year before (y-1) to 2 (y1) and 2 (y2) years after diagnosis. SA and DP prevalence was calculated. Odds ratios (AOR) were determined for factors associated with using long-term (SA > 180 days or DP > 0 days) sickness benefits.

RESULTS

Prevalence of SA and DP was 56.0% and 24.8% during y-1, 69.9% and 28.9% during y1, and 64.0% and 34.7% during y2, respectively. Odds of using long-term sickness benefits were higher y1 and y2 in patients using long-term sickness benefits the year before diagnosis (AOR = 3.82, 95% CI 2.91-5.02; AOR = 4.31, 95% CI 2.96-6.29, respectively) and y2 in patients with mBC diagnosis 1997-2000 (AOR = 1.84, 95% CI 1.10-3.08) and using long-term sickness benefits the year after diagnosis (AOR = 22.10, 95% CI 14.33-34.22).

CONCLUSIONS

The prevalence of sickness benefit utilisation was high and increased after mBC diagnosis, particularly for patients using long-term sickness benefits prior to diagnosis. Additional study is needed to determine factors that might reduce the need for sickness benefits and enhance work ability in these patients.

Return to work and sick leave patterns following a work injury among young adults: a study protocol of a Swedish multimodal study

INTRODUCTION

There is a lack of studies that focus exclusively on return to work (RTW) and sick leave patterns following a work injury among young adults. This study aims to close the gap by contributing with knowledge regarding young adults' sick leave pattern after a work injury and their experience of RTW after a work injury in Sweden.

METHODS AND ANALYSIS

The present study is a multimodal study, which will use Swedish national register data and qualitative data collection by photovoice. Injuries classified as work injuries according to the Swedish injury classification were included. Registry data will be retrieved from the Swedish National-based registers of Swedish Information System on Occupational Accidents and Work-related diseases, the Swedish Social Insurance Agency's database MicroData for Analysis of Social Insurance and the Swedish Longitudinal Integration Database for Health Insurance and Labour Market Studies. Persons who have registered a work injury at the Swedish Work Environment Authority in 2012 will be included. Sick leave patterns will be analysed using group-based trajectory models and multivariate analyses to explore how sick leave patterns have developed over 5 years. Subsequently, a participatory approach using photovoice method will be conducted to explore young adults' perceptions of barriers and facilitators in RTW after a work injury. Results from the photovoice group sessions will be analysed using a grounded theoretical approach.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the Ethical Review Board (case number 2019/028-6) in Sweden. Results of the study will be disseminated through peer-reviewed journals, print and media presentation, conferences and via reports to the funding agency.

Sickness absence and disability pension among women with breast cancer: a population-based cohort study from Sweden

BACKGROUND

Women's return to work after diagnosis of breast cancer (BC) is becoming more prevalent. However, register-based national investigation on sickness absence (SA) and disability pension (DP) in BC women is lacking. The aim of the study was to explore SA and DP before and after a first BC diagnosis and the possibility to predict new cancer-related SA by using disease-related and sociodemographic factors.

METHODS

A longitudinal register study of the 3536 women in Sweden aged 19-64 with a first BC diagnosis in 2010 was conducted by linkage of five nationwide registers. Particularly, detailed information on SA and DP was obtained from the National Social Insurance Agency. Descriptive statistics on SA and DP 2 years before through 3 years after the BC diagnosis were performed. The risk of having a new SA spell due to BC or BC-related diagnoses was modeled using logistic regression.

RESULTS

The proportion of women with SA increased during the year following the BC diagnosis date and declined over the next 2 years to proportions before diagnosis. At the time of BC diagnosis, half of the women began a new SA spell > 14 days with cancer, cancer-related, or mental diagnosis. Disease-related and sociodemographic factors including occupational sector, living area, age, cancer stage, educational level, and number of previous SA days showed statistical significance (p < 0.05) in predicting a new SA around BC diagnosis. By using these factors, it was possible to correctly predict 67% of the new SA spell.

CONCLUSIONS

SA among women with BC was elevated mainly in the first year after diagnosis. New SA following BC diagnosis can accurately be predicted.

Sickness absence and disability pension among swedish women prior to breast cancer relapse with a special focus on the roles of treatment and comorbidity

OBJECTIVE

We aimed to determine the longitudinal prevalence and the predictors of sickness absence (SA) and disability pension (DP) in breast cancer (BC) women who eventually developed relapse.

METHODS

A total of 1293 BC women, who were ages 20-63 years, diagnosed between 1996 and 2011 and by 2016 had all developed relapse, were identified in Swedish registers and were followed from two years before to five years after their primary diagnosis, while they were relapse-free. Annual prevalence of SA and DP was calculated. Logistic regression was used to estimate adjusted odds ratios (AOR) for long-term SA (>30 days) at one (y1) and three (y3) years post-diagnosis.

RESULTS

Prevalence of long-term SA was 68.1% in y1 and 16.3% in y5. Prevalence of DP progressively increased from 16.3% in y1 to 29.0% in y5. Predictors of long-term SA included age <50 years (y1:AOR = 1.79 [1.39-2.29]), TNM stage III (y1:AOR = 1.54 [1.03-2.31]; y3:AOR = 2.21 [1.32-3.72]), metastasis (y1:AOR = 1.64 [1.26-2.12]; y3:AOR = 1.51 [1.05-2.18]), comorbidity (y1:AOR = 2.41 [1.55-3.76]; y3 AOR = 4.62 [2.49-8.57]) and any combination of radiotherapy, chemotherapy and hormonal therapy (y1:AOR = 2.05-5.71).

CONCLUSION

Among BC women who later developed relapse, those who had higher stages of BC, had comorbidity and received neoadjuvant and/or adjuvant therapy were at significantly higher risk of needing long-term SA after their diagnosis.

Sequence analysis of sickness absence and disability pension in the year before and the three years following a bicycle crash; a nationwide longitudinal cohort study of 6353 injured individuals

Background

Bicyclists are the road user group with the highest number of severe injuries in the EU, yet little is known about sickness absence (SA) and disability pension (DP) following such injuries.

Aims

To explore long-term patterns of SA and DP among injured bicyclists, and to identify characteristics associated with the specific patterns.

Methods

A longitudinal register-based study was conducted, including all 6353 individuals aged 18–59 years and living in Sweden in 2009, who in 2010 had incident in-patient or specialized out-patient healthcare after a bicycle crash. Information about sociodemographic factors, the injury, SA (SA spells > 14 days), and DP was obtained from nationwide registers. Weekly SA/DP states over 1 year before through 3 years after the crash date were used in sequence and cluster analyses. Multinomial logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for factors associated with each identified sequence cluster.

Results

Seven clusters were identified: “No SA or DP” (58.2% of the cohort), “Low SA or DP” (7.4%), “Immediate SA” (20.3%), “Episodic SA” (5.9%), “Long-term SA” (1.7%), “Ongoing part-time DP” (1.7%), and “Ongoing full-time DP” (4.8%). Compared to the cluster “No SA or DP”, all other clusters had higher ORs for women, and higher age. All clusters but “Low SA and DP” had higher ORs for inpatient healthcare. The cluster “Immediate SA” had a higher OR for: fractures (OR 4.3; CI 3.5–5.2), dislocation (2.8; 2.0–3.9), sprains and strains (2.0; 1.5–2.7), and internal injuries (3.0; 1.3–6.7) compared with external injuries. The cluster “Episodic SA” had higher ORs for: traumatic brain injury, not concussion (4.2; 1.1–16.1), spine and back (4.5; 2.2–9.5), torso (2.5; 1.4–4.3), upper extremities (2.9; 1.9–4.5), and lower extremities (3.5; 2.2–5.5) compared with injuries to the head, face, and neck (not traumatic brain injuries). The cluster “Long-term SA” had higher ORs for collisions with motor vehicles (1.9;1.1–3.2) and traumatic brain injury, not concussion (18.4;2.2–155.2).

Conclusion

Sequence analysis enabled exploration of the large heterogeneity of SA and DP following a bicycle crash. More knowledge is needed on how to prevent bicycle crashes and especially those crashes/injuries leading to long-term consequences.

Long-term cervical cancer survivors on disability pension: a subgroup in need of attention from health care providers

PURPOSE

Survivors of cervical cancer have an increased risk for permanently reduced work ability qualifying for disability pension (DP). Few studies describe the social and health situation of long-term survivors of cervical cancer (LSCCs) on DP as a subgroup among LSCCs. The purpose was to investigate the socio-demographic and health status of LSCCs holding DP in a population-based cohort using LSCCs holding paid work as reference.

METHODS

Altogether, 354 LSCCs under 67 years (age of retirement pension in Norway) at survey participated in this study. They responded to a mailed questionnaire containing social, health, and clinical issues.

RESULTS

Among LSCCs 24% held DP at a median of 11 years (range 6-15) after diagnosis versus 12% in the general female population. Compared to LSCCs in paid work, those on DP had significantly higher mean age at survey, short education, more comorbid somatic diseases, poorer self-rated health, higher level of neurotoxic side effects, more chronic fatigue, and higher mean levels of anxiety and depression. Increased age, presence of musculo-skeletal diseases, and increased levels of depression and pain remained significantly associated with DP in multivariate analysis.

CONCLUSIONS

One in four LSCCs held DP which was twice the rate of the general female population. Several somatic and psychological conditions amenable to treatment were significantly associated with holding DP.

IMPLICATIONS FOR CANCER SURVIVORS

LSCCs holding DP should check their health regularly since conditions that can be treated are common, and health care providers should be aware of this opportunity.

Introduction to special section on: current topics in cancer survivorship and work

Work is a key contributor to quality of life and an important aspect of cancer survivorship. We call attention to current topics in cancer survivorship and work with 12 articles on cancer survivorship and work in this special section. The focus is on less studied diagnostic groups such as gastrointestinal cancer and prostate cancer, and on long-term effects of cancer diagnosis and treatment on work. Furthermore, studies are included on topics not generally studied including cognitive limitations and pain, the role of the employer on work outcomes among different types of cancer survivors and some countries not typically covered in the existing literature on work and cancer survivorship. We conclude that to improve sustainable work participation in cancer survivors, personalised, tailored interventions should be provided. A prerequisite for this is the identification of groups and individuals at high risk for adverse work outcomes. In order to develop such interventions, research involving new approaches such as matching data registries, participatory approaches and the involvement of many stakeholders and survivors with these different types of cancer diagnoses is necessary. IMPLICATIONS FOR CANCER SURVIVORS: The goal of sustainable work participation in cancer survivors can be improved by the delivery of a personalised or risk-based tailored intervention. Furthermore, successful work outcomes often involve many stakeholders who should all be included Implications for Cancer Survivors. The goal of sustainable work participation in cancer survivors can be improved by the delivery of a personalised or risk-based tailored intervention. Furthermore, successful work outcomes often involve many stakeholders who should all be included.

Long-term work retention after treatment for cancer: a systematic review and meta-analysis

PURPOSE

Almost half of people diagnosed with cancer are working age. Survivors have increased risk of unemployment, but little is known about long-term work retention. This systematic review and meta-analysis assessed work retention and associated factors in long-term cancer survivors.

METHODS

We searched Medline/Pubmed, Embase, PsychINFO, and CINAHL for studies published 01/01/2000-08/01/2019 reporting work retention in adult cancer survivors ≥ 2 years post-diagnosis. Survivors had to be in paid work at diagnosis. Pooled prevalence of long-term work retention was estimated. Factors associated with work retention from multivariate analysis were synthesized.

RESULTS

Twenty-nine articles, reporting 21 studies/datasets including 14,207 cancer survivors, were eligible. Work retention was assessed 2-14 years post-diagnosis. Fourteen studies were cross-sectional, five were prospective, and two contained both cross-sectional and prospective elements. No studies were scored as high quality. The pooled estimate of prevalence of long-term work retention in cancer survivors working at diagnosis was 0.73 (95%CI 0.69-0.77). The proportion working at 2-2.9 years was 0.72; at 3-3.9 years 0.80; at 4-4.9 years 0.75; at 5-5.9 years 0.74; and 6+ years 0.65. Pooled estimates did not differ by cancer site, geographical area, or study design. Seven studies assessed prognostic factors for work retention: older age, receiving chemotherapy, negative health outcomes, and lack of work adjustments were associated with not working.

CONCLUSION

Almost three-quarters of long-term cancer survivors working at diagnosis retain work.

IMPLICATIONS FOR CANCER SURVIVORS

These findings are pertinent for guidelines on cancer survivorship care. Professionals could focus support on survivors most likely to have poor long-term work outcomes.

Trajectories of sickness absence and disability pension in the 2 years before and 3 years after breast cancer diagnosis: A Swedish longitudinal population-based cohort study

BACKGROUND

After breast cancer (BC) diagnosis, work incapacity often occurs among working-age women. We investigated the trajectories of previous and subsequent sickness absence and/or disability pension (SA/DP) days, and risk factors for consistently high levels of future SA/DP among these women.

METHODS

This longitudinal cohort study included all 3536 women in Sweden aged 19-64 years who received a first BC diagnosis in 2010. Their annual SA/DP net days from 2 years before to 3 years after diagnosis were calculated. SA/DP patterns were depicted by a group-based trajectory model. Logistic regressions were used to calculate odds ratios (ORs) with 95% CIs of >90 or >180 SA/DP days/year.

RESULTS

Three trajectories of SA/DP days/year were identified: increasing only in year₊₁ (61% of all), increasing then decreasing in year₊₃ (30%), and constantly very high (9%). The risk factors associated with annual SA/DP days >90 (long) and >180 days (extreme long) were similar. Factors associated with having >90 SA/DP days for years 1-3 were: stage II (OR, 4.59; 95% CI, 2.98-7.07), stage III+IV (OR, 26.57; 95% CI, 13.52-52.22), prediagnosis SA 1-30 days (OR, 2.73; 95% CI, 1.30-5.70), prediagnosis SA >90 days (OR, 24.52; 95% CI, 12.25-49.08), and prediagnosis DP (OR, 659.97; 95% CI, 292.52->999.99). Conversely, adjusting for prediagnosis SA/DP and stage, sociodemographic factors were not associated with high levels of SA/DP.

CONCLUSION

After BC diagnosis, SA/DP increased significantly but then decreased. The absolute majority had no SA/DP during year 3. Advanced cancer stage and previous high SA/DP rendered the greatest risk for future high SA/DP. More knowledge is needed for applying the information in rehabilitation and return-to-work planning.

Impact of Breast Cancer Treatment on Employment: Results of a Multicenter Prospective Cohort Study (CANTO)

PURPOSE

Adverse effects of breast cancer treatment can negatively affect survivors’ work ability. Previous reports lacked detailed clinical data or health-related patient-reported outcomes (PROs) and did not prospectively assess the combined impact of treatment and related sequelae on employment.

METHODS

We used a French prospective clinical cohort of patients with stage I-III breast cancer including 1,874 women who were working and ≥ 5 years younger than legal retirement age (≤ 57 years) at breast cancer diagnosis. Our outcome was nonreturn to work (non-RTW) 2 years after diagnosis. Independent variables included treatment characteristics as well as toxicities (Common Toxicity Criteria Adverse Events [CTCAE] v4) and PROs (European Organization for Research and Treatment of Cancer [EORTC] Quality of life Questionnaires, Breast cancer module [QLQ-BR23] and Fatigue module [QLQ-FA12], Hospital Anxiety and Depression Scale) collected 1 year after diagnosis. Logistic regression models assessed correlates of non-RTW, adjusting for age, stage, comorbidities, and socioeconomic covariates.

RESULTS

Two years after diagnosis, 21% of patients had not returned to work. Odds of non-RTW were significantly increased among patients treated with combinations of chemotherapy and trastuzumab (odds ratio [OR] v chemotherapy-hormonotherapy: for chemotherapy-trastuzumab, 2.01; 95% CI, 1.18 to 3.44; for chemotherapy-trastuzumab-hormonotherapy, 1.62; 95% CI, 1.10 to 2.41). Other significant associations with non-RTW included grade ≥ 3 CTCAE toxicities (OR v no, 1.59; 95% CI, 1.15 to 2.18), arm morbidity (OR v no, 1.59; 95% CI, 1.19 to 2.13), anxiety (OR v no, 1.47; 95% CI, 1.02 to 2.11), and depression (OR v no, 2.29; 95% CI, 1.34 to 3.91).

CONCLUSION

Receipt of systemic therapy combinations including trastuzumab was associated with increased odds of non-RTW. Likelihood of unemployment was also higher among patients who reported severe physical and psychological symptoms. This comprehensive study identifies potentially vulnerable patients and warrants supportive interventional strategies to facilitate their RTW.

Occupational Class Differences in Long-Term Sickness Absence Due to Breast Cancer during 2005-2013: A Population-Based Study among Finnish Women

Breast cancer is the most common cancer among women in Western countries with clear socioeconomic differences. Higher occupational class is associated with higher breast cancer incidence but with better survival from the disease, whereas lower occupational class is associated with higher risk of sickness absence. We are not aware of previous studies examining changes over time in occupational class differences in sickness absence due to breast cancer. This paper focuses on occupational class differences in the incidence and duration of sickness absence due to breast cancer over the period of 2005-2013. Age-adjusted occupational class differences in the cumulative incidence and duration of sickness absence due to breast cancer were calculated utilising a nationally representative 70% random sample of employed Finnish women aged 35-64 years (yearly N varying between 499,778 and 519,318). The results show that higher occupational class was associated with higher annual cumulative incidence of sickness absence due to breast cancer. Lower occupational class was associated with longer duration of absence. Occupational class differences in both cumulative incidence and duration of absence remained broadly stable. As a conclusion, these results suggest that measures should be targeted particularly to promotion of work capacity among employees with breast cancer in lower occupational classes.

Women's experiences of encounters with healthcare professionals' regarding work after breast-cancer surgery and associations with sickness absence: a 2-year follow-up cohort study

INTRODUCTION

Breast cancer (BC) is the most common cancer among women, and half of those diagnosed are of working age. Positive encounters regarding work from healthcare professionals have been shown to promote return to work among sickness absentees in general. However, the knowledge about encounters possible associations with sickness absence (SA) in women with BC is scarce.

AIM

To explore if women had experienced encounters regarding work from healthcare professionals during the first year after BC surgery and if this was associated with SA during the second year after surgery, controlled for treatment and sociodemographic effects.

METHODS

A prospective cohort study of 690 Swedish women with primary BC, aged 24-63 years included after surgery. Descriptive statistics and adjusted logistic regression (age, birth country, education, self-rated health, treatment) with 95% confidence intervals (CI) were used.

RESULTS

Eighty percent of the women had experienced encounters regarding work. Women who got advice and support regarding work (adjusted odds ratio (OR) 0.5; 0.3-0.9) or were encouraged to work (adjusted OR 0.6; 0.3-0.9) had less SA. A larger proportion of those encouraged to work had less advanced cancer, surgery, hormone, or radiotherapy. Consistently, women encouraged to be on SA had more SA, but this was partly explained by disease or treatment factors (crude OR 1.6; 1.1-2.4, adjusted OR 1.2 (0.8-1.9) since a larger proportion of those with more advanced cancer, surgery, or chemotherapy had more SA.

CONCLUSION

Most women experienced encounters regarding work, and the nature of these encounters were associated with SA 2 years after BC surgery.

The longitudinal integrated database for health insurance and labour market studies (LISA) and its use in medical research

Education, income, and occupation are factors known to affect health and disease. In this review we describe the Swedish Longitudinal Integrated Database for Health Insurance and Labour Market Studies (LISA, Longitudinell Integrationsdatabas för Sjukförsäkrings- och Arbetsmarknadsstudier). LISA covers the adult Swedish population aged ≥ 16 years registered on December 31 each year since 1990 (since 2010 individuals aged ≥ 15 years). The database was launched in response to rising levels of sick leave in the country. Participation in Swedish government-administered registers such as LISA is compulsory, and hence selection bias is minimized. The LISA database allows researchers to identify individuals who do not work because of injury, disease, or rehabilitation. It contains data on sick leave and disability pension based on calendar year. LISA also includes information on unemployment benefits, disposable income, social welfare payments, civil status, and migration. During 2000–2017, an average of 97,000 individuals immigrated to Sweden each year. This corresponds to about 1% of the Swedish population (10 million people in 2017). Data on occupation have a completeness of 95%. Income data consist primarily of income from employment, capital, and allowances, including parental allowance. In Sweden, work force participation is around 80% (2017: overall: 79.1%; men 80.3% and women 77.9%). Education data are available in > 98% of all individuals aged 25–64 years, with an estimated accuracy for highest attained level of education of 85%. Some information on civil status, income, education, and employment before 1990 can be obtained through the Population and Housing Census data (FoB, Folk- och bostadsräkningen).

Experiences of positive encounters with healthcare professionals among women on long-term sickness absence due to breast cancer or due to other diagnoses: a nationwide survey

Background

Experiences of encounters with professionals have been shown to influence return to work (RTW) among sickness absentees in general. The aim was to gain knowledge on experiences of encounters with healthcare professionals and the ability to RTW among women on long-term sickness absence (SA) due to breast cancer (BC) compared to among women on long-term SA due to other diagnoses.

Methods

Analyses of questionnaire data about experiences of encounters with healthcare professionals among 6197 women aged 19–65 years and on a SA spell lasting 4–8 months. Of those, 187 were on SA due to BC. Descriptive statistics and adjusted (for age, birth country, educational level, depressive symptoms) logistic regression analyses with 95% confidence intervals (CI) were conducted.

Results

About 95% in both groups of women stated that they had experienced positive encounters with healthcare, and a minority, about 20%, had experienced negative encounters. Four specific types of positive encounters had been experienced to a lesser extent by women with BC: “allowed me to take own responsibility” (odds ratio (OR) 0.6; 95% CI 0.4–0.8), “encouraged me to carry through my own solutions” (OR 0.5; 95% CI 0.4–0.7), “made reasonably high demands” (OR 0.6; 95% CI 0.4–0.9), and “sided with me/stood on my side” (OR 0.6; 95% CI 0.4–0.8). Among the women with BC, 46% stated that positive encounters promoted their ability to RTW compared to 56% among the others. Conclusion: Most of the women had experienced positive encounters and about half stated that positive encounters promoted their ability to RTW, although a slightly smaller proportion of the women with BC stated that. This study emphasizes that not only medical treatment but also encounters may influence the ability to RTW, something that is of clinical importance.

Unemployment following breast cancer diagnosis: A population-based study

OBJECTIVES

The population of breast cancer survivors is growing. In Western societies, many of these women are working age, and therefore, potentially desire to return to the work force. We aimed to evaluate the unemployment risk for up to 8 years following a breast cancer diagnosis and identify contributing socio-economic factors.

METHODS

This historical prospective study included baseline measurements from the Israeli Central Bureau of Statistics 1995 National Census, with follow-up to 2011. We retrieved data on employment from the Israeli Tax Authority database and cancer status from the National Cancer Registry. A control group without cancer was selected to match the patients. Analyses were controlled for socio-economic factors and the baseline employment status 2 years prior to diagnosis.

RESULTS

We retrieved data for 2341 patients with breast cancer and 6837 age-matched women without cancer. We found an elevated risk of unemployment during the 8 years after breast cancer diagnosis (2-year OR 1.82, 95%CI: 1.59-2.075; 8-year OR 1.26, 95%CI: 1.07-1.47). Age and all examined socio-economic variables were correlated to increased risk of unemployment. The strongest predictor was pre-diagnosis unemployment (2-year OR 18.95, 95%CI: 16.68-21.52; 8-year OR 4.92, 95%CI: 4.07-5.96). Surprisingly, patients with axillary involvement were associated with less risk of unemployment than other patients.

CONCLUSIONS

Breast cancer survivorship was associated with long-term risk of unemployment. Older patients and patients with lower socio-economic status were at increased risk of unemployment.

Factors Affecting Sick Leave Duration for Non-Work-Related Temporary Disabilities in Brazilian University Public Servants

Sickness absenteeism in public institutions compromises the execution of services, and may also generate direct impacts on the population that receives coverage. To determine if sick leave duration for temporary disabilities is associated with non-work-related illnesses (NWRI), a historical cohort study was carried out of workers at a Brazilian University. The Charlson Comorbidity Index (CCI) was obtained from the most prevalent diagnoses in each expert examination and from the corresponding days of sick leave per episode, adjusting simple and multiple Cox regression models. As a result, 70% of the NWRI temporary disabilities were due to depressive disorders, convalescence, and dorsalgia with a sick leave duration between 4 and 320 days. The factors of protection for sick leave durations until the rehabilitation were non-insulin-dependent diabetes mellitus and hypertension. Long-term sick leaves were observed in the cases that required rehabilitation of those workers diagnosed with recurrent depressive disorders, conjunctivitis, acute sinusitis, skin disorders, calculus of kidney and ureter, abdominal and pelvic pain, and same-level fall accidents. It is also worth noting that even in a disease that can justify long-term sick leaves, such as breast cancer, the duration may be shorter according to the worker’s capacity and self-efficacy.

Loss in working years after a breast cancer diagnosis

Background:

Breast cancer can negatively influence working life, but it is unclear how many working years women with breast cancer can expect to lose.

Methods:

Women diagnosed with breast cancer between 1997 and 2012 were identified in the Breast Cancer Data Base Sweden (N=19 661), together with breast cancer-free comparison women (N=81 303). Using flexible parametric survival modelling, the loss in working years was calculated as the difference in the remaining years in the work force between women with and without breast cancer.

Results:

Women aged 50 years at diagnosis with stage I disease lost on average 0.5 years (95% CI, 0.2–0.7) of their remaining working time; the corresponding estimates were 0.9 years (0.5–1.2) in stage II, 2.5 years (1.9–3.1) in stage III and 8.1 years (6.5–9.7) in stage IV. Women with in situ breast cancer did not lose any working years. The strongest treatment determinant was axillary lymph node dissection.

Conclusions:

We found a loss in working years not only in late but also in early-stage breast cancer. Although it is reassuring that some groups had no or only a modest work loss, the economic consequences for society are considerable given the large number of women annually diagnosed with breast cancer.

Cancer immunotherapy beyond immune checkpoint inhibitors

Malignant cells have the capacity to rapidly grow exponentially and spread in part by suppressing, evading, and exploiting the host immune system. Immunotherapy is a form of oncologic treatment directed towards enhancing the host immune system against cancer. In recent years, manipulation of immune checkpoints or pathways has emerged as an important and effective form of immunotherapy. Agents that target cytotoxic T lymphocyte-associated molecule-4 (CTLA-4), programmed cell death receptor-1 (PD-1), and programmed cell death ligand-1 (PD-L1) are the most widely studied and recognized. Immunotherapy, however, extends beyond immune checkpoint therapy by using new molecules such as chimeric monoclonal antibodies and antibody drug conjugates that target malignant cells and promote their destruction. Genetically modified T cells expressing chimeric antigen receptors are able to recognize specific antigens on cancer cells and subsequently activate the immune system. Native or genetically modified viruses with oncolytic activity are of great interest as, besides destroying malignant cells, they can increase anti-tumor activity in response to the release of new antigens and danger signals as a result of infection and tumor cell lysis. Vaccines are also being explored, either in the form of autologous or allogenic tumor peptide antigens, genetically modified dendritic cells that express tumor peptides, or even in the use of RNA, DNA, bacteria, or virus as vectors of specific tumor markers. Most of these agents are yet under development, but they promise to be important options to boost the host immune system to control and eliminate malignancy. In this review, we have provided detailed discussion of different forms of immunotherapy agents other than checkpoint-modifying drugs. The specific focus of this manuscript is to include first-in-human phase I and phase I/II clinical trials intended to allow the identification of those drugs that most likely will continue to develop and possibly join the immunotherapeutic arsenal in a near future.
