A controlled study of income development for breast cancer survivors in Norway

Out-of-pocket payments and loss of income among long-term breast cancer survivors in Germany: a multi-regional population-based study

PURPOSE

This study aims to examine the magnitude of out of pocket (OOP) payments and income loss, as well as to identify socioeconomic and clinical factors among long-term breast cancer (BC) survivors in Germany.

METHODS

We examine data from 2654 long-term BC survivors in Germany that participated in the "CAncEr Survivorship - A multi-Regional population-based study" (CAESAR) and who were at least 5 years post diagnosis. BC-related OOP payments and income loss both within the 12 months prior to the survey were analyzed. Two-part regression models were performed to identify socioeconomic and clinical factors.

RESULTS

OOP payments were incurred by 51.9% of survivors with a total mean spending of 566 euros. Income loss was present among 9.6% of survivors and averaged 5463 euros among those reporting such. Socioeconomic and clinical factors associated with higher OOP payments (p ≤ 0.05) included age at time of diagnosis (65-79 years), education (10-11 years), (early) retirement, stage of diagnosis (stage III), time from diagnosis (more than 10 years), comorbidities (at least 1), and the use of rehabilitation services. Regarding income loss, age at time of diagnosis (50-59 years), (early) retirement, stage of diagnosis (stage II), time from diagnosis (5-7 years), comorbidities (at least 1), and receiving chemotherapy treatment were associated with higher losses.

CONCLUSIONS

For some survivors in Germany, financial burden can be considerably high despite comprehensive healthcare and support from social security.

IMPLICATIONS FOR CANCER SURVIVORS

OOP payments related to domestic help and nursing staff as well as to outpatient care are most frequent.

Short-term effect of colorectal cancer on income: analysis of an Italian cohort

INTRODUCTION

The ability to return to work after a cancer diagnosis is a key aspect of cancer survivorship and quality of life. Studies have reported a significant risk of income loss for cancer survivors; however, there is limited evidence of the Italian context.

METHODS

The Work Histories Italian Panel (WHIP)-Salute database was used to select a cohort of incident cases of colorectal cancer (CRC) among workers in the private sector, based on hospital discharges. A propensity score matching was used to find a balanced control group for several confounders. Ordinary least square and logistic regressions were used to estimate the effect of a CRC diagnosis on annual income and the probability of switching from a full-time contract to a part-time one considering 3 years after the diagnosis.

RESULTS

Overall, we identified 925 CRC incident cases from 2006 until 2012. Our results confirm a statistically significant reduction in survivors' income compared with controls. This reduction was greater in the first year and then tend to decrease, with an average income loss over 3 years of about €12 000. Stratified analyses by sex and position confirmed the overall trend while indicating a strong effect modification. Regarding the switching from full-time to part-time employment, the results were never significant.

CONCLUSION

Income loss does not seem to be related to an increase in part-time contracts, but rather to survivors' reduced work capacity following the invasive treatments. Further research is needed to investigate the complex dynamics behind this association.

Joint exposure to parental cancer and income loss during childhood and the child's socioeconomic position in early adulthood: a Danish and Norwegian register-based cohort study

BACKGROUND

Parental cancer as well as economic hardship in the family during childhood can affect the child negatively. Our aim was to examine the association between the joint exposure to parental cancer and income loss in childhood and the child's socioeconomic position in early adulthood.

METHODS

We conducted a register-based prospective cohort study of children born in Denmark between 1978 and 1986 and in Norway between 1979 and 1987. The children were followed from 1 January 1994 (in Denmark) or 1995 (in Norway). Educational level and personal income were measured at age 30 years. Children who experienced parental cancer between the years they turned 8 and 16 years were identified, and exposure to income loss was measured in the same period. Adjusted multinomial logistic regression model was used to estimate relative risk ratios for the joint exposure of parental cancer and income loss during childhood.

RESULTS

Children who experienced parental cancer and an income loss during childhood had an increased risk of low education and lower income at age 30 years. The associations were weaker for children only exposed to income loss and less clear for those only exposed to parental cancer. Further, exposure to parental cancer with a severe cancer type was associated with lower educational level.

CONCLUSION

The child's educational attainment and income level in early adulthood were negatively affected by exposure to income loss in childhood, and even more so if exposed to both parental cancer and income loss. The associations with educational attainment were stronger for more severe cancer types.

Longitudinal Assessment of Labor Market Earnings Among Patients Diagnosed With Cancer in Canada

IMPORTANCE

To our knowledge, there have been no studies that estimated the short-, mid-, and long-term effects on cancer survivors' labor market earnings using administrative data.

OBJECTIVE

To estimate the change in labor market earnings due to cancer diagnosis stratified by cancer type and age category.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cohort study used a retrospective analysis of Statistics Canada's administrative linkage file, which includes microdata from the 1991 Census, the Canadian Cancer Registry, mortality records, and personal income tax files. Participants included patients newly diagnosed with cancer from 1992 to 2008. All statistical analyses were finished on September 30, 2020.

EXPOSURES

Cancer diagnosis using the International Classification of Diseases, Ninth Revision, and the International Classification of Diseases, Tenth Revision.

MAIN OUTCOMES AND MEASURES

Annual and percent change in labor market earnings. The empirical strategy used a combination of the Mahalanobis distance and propensity score matching method and the difference-in-difference regression method to select a control group similar to the cancer survivors in this study and assess the association of the cancer diagnosis with labor market earnings, respectively.

RESULTS

A total of 59 532 patients with cancer and 243 446 patients without cancer were included in the main analysis. The mean (SD) age was similar between the matched treatment and control cohort (49.70 [8.1] years vs 49.68 [7.2] years), as was the proportion of females (0.49 vs 0.49), and the individual reported income ($37 937 [$18 645] vs $37 396 [$16 876]). The results showed the negative associations of cancer with labor market earnings. Additionally, the severity of the cancer was associated with labor market earnings, where cancer survivors with a severe type of cancer in terms of the 5-year survival rate are shown to have a larger and more persistent earnings difference compared with the control group.

CONCLUSIONS AND RELEVANCE

The findings of this cohort study suggest that labor market earnings losses are associated with a cancer diagnosis. A better understanding of the loss of labor market earnings following cancer diagnosis and by cancer type can play an important role in starting a dialogue in future policy initiatives to mitigate the financial burden faced by cancer survivors.

Socioeconomic inequalities in stage-specific breast cancer incidence: a nationwide registry study of 1.1 million young women in Norway, 2000-2015

BACKGROUND

Women with high socioeconomic status (SES) have the highest incidence rates of breast cancer. We wanted to determine if high SES women only have higher rates of localized disease, or whether they also have higher rates of non-localized disease. To study this, we used data on a young population with universal health care, but not offered screening.

MATERIAL AND METHODS

Using individually linked registry data, we compared stage-specific breast cancer incidence, by education level and income quintile, in a Norwegian cohort of 1,106,863 women aged 30-48 years during 2000-2015 (N = 7531 breast cancer cases). We calculated stage-specific age-standardized rates and incidence rate ratios and rate differences using Poisson models adjusted for age, period and immigration history.

RESULTS

Incidence of localized and regional disease increased significantly with increasing education and income level. Incidence of distant stage disease did not vary significantly by education level but was significantly reduced in the four highest compared to the lowest income quintile. The age-standardized rates for tertiary versus compulsory educated women were: localized 28.2 vs 19.8, regional 50.8 vs 40.4 and distant 2.3 vs 2.6 per 100,000 person-years. The adjusted incidence rate ratios (tertiary versus compulsory) were: localized 1.40 (95% CI 1.25-1.56), regional 1.25 (1.15-1.35), distant 0.90 (0.64-1.26). The age-standardized rates for women in the highest versus lowest income quintile were: localized 28.9 vs 17.7, regional 52.8 vs 41.5 and distant 2.3 vs 3.2 per 100,000 person-years. The adjusted incidence rate ratios (highest versus lowest quintile) were: localized 1.63 (1.42-1.87), regional 1.27 (1.09-1.32), distant 0.64 (0.43-0.94).

CONCLUSION

Increased breast cancer rates among young high SES women is not just increased detection of small localized tumors, but also increased incidence of tumors with regional spread. The higher incidence of young high SES women is therefore real and not only because of excessive screening.

Stage-specific survival has improved for young breast cancer patients since 2000: but not equally

Purpose

The stage-specific survival of young breast cancer patients has improved, likely due to diagnostic and treatment advances. We addressed whether survival improvements have reached all socioeconomic groups in a country with universal health care and national treatment guidelines.

Methods

Using Norwegian registry data, we assessed stage-specific breast cancer survival by education and income level of 7501 patients (2317 localized, 4457 regional, 233 distant and 494 unknown stage) aged 30–48 years at diagnosis during 2000–2015. Using flexible parametric models and national life tables, we compared excess mortality up to 12 years from diagnosis and 5-year relative survival trends, by education and income as measures of socioeconomic status (SES).

Results

Throughout 2000–2015, regional and distant stage 5-year relative survival improved steadily for patients with high education and high income (high SES), but not for patients with low education and low income (low SES). Regional stage 5-year relative survival improved from 85 to 94% for high SES patients (9% change; 95% confidence interval: 6, 13%), but remained at 84% for low SES patients (0% change; − 12, 12%). Distant stage 5-year relative survival improved from 22 to 58% for high SES patients (36% change; 24, 49%), but remained at 11% for low SES patients (0% change; − 19, 19%).

Conclusions

Regional and distant stage breast cancer survival has improved markedly for high SES patients, but there has been little survival gain for low SES patients. Socioeconomic status matters for the stage-specific survival of young breast cancer patients, even with universal health care.

The long-term financial consequences of breast cancer: a Danish registry-based cohort study

BACKGROUND

A breast cancer diagnosis affects an individual's affiliation to labour market, but the long-term consequences of breast cancer on income in a Danish setting have not been examined. The present study investigated whether breast cancer affected future income among Danish women that participated in the work force. We also examined the roles of sociodemographic factors and prior psychiatric medical treatment.

METHODS

This registry-based cohort study was based on information retrieved from linked Danish nationwide registries. We compared the incomes of 13,101 women (aged 30-59 years) diagnosed with breast cancer (exposed) to those of 60,819 women without breast cancer (unexposed). Changes in income were examined during a 10-year follow-up; for each follow-up year, we calculated the mean annual income and the relative change compared to the income earned one year prior to diagnosis. Expected changes in Danish female income, according to calendar year and age, were estimated based on information from Statistics Denmark. For exposed and unexposed groups, the observed income changes were dichotomized to those above and those below the expected change in income in the Danish female population. We examined the impact of breast cancer on income each year of follow-up with logistic regression models. Analyses were stratified according to educational level, marital status, and prior psychiatric medical treatment.

RESULTS

Breast cancer had a temporary negative effect on income. The effect was largest during the first three years after diagnosis; thereafter, the gap narrowed between exposed and unexposed cohorts. The odds ratio for an increase in income in the cancer cohort compared to the cancer-free cohort was 0.81 (95% CI 0.77-0.84) after three years. After seven years, no significant difference was observed between cohorts. Stratified analyses demonstrated that the negative effect of breast cancer on income lasted longest among women with high educational levels. Being single or having received psychiatric medical treatment increased the chance to experience an increase in income among women with breast cancer.

CONCLUSION

A breast cancer diagnosis led to negative effects on income, which ameliorated over the following seven years. Sociodemographic factors and prior psychiatric medical treatment might influence long-term consequences of breast cancer on income.

Undesirable financial effects of head and neck cancer radiotherapy during the initial treatment period

BACKGROUND

Healthcare cost and reforms are at the forefront of international debates. One of the current discussion themes in oncology is whether and how patients' life changes due to costs of cancer care. In Norway, the main part of the treatment costs is supported by general taxpayer revenues.

OBJECTIVES

The objective of this study was to clarify whether head and neck cancer patients (n=67) in northern Norway experienced financial health-related quality of life (HRQOL) deterioration due to costs associated with treatment.

DESIGN

HRQOL was examined by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 in the beginning and in the end of radiation treatment in patients treated at the University Hospital in Northern Norway. Changes in financial HRQOL were calculated and compared by paired sample T-tests. Multiple regression analyses were used to examine correlations among gender, marital status, age and treatment with or without additional chemotherapy and changes in the HRQOL domain of financial difficulties.

RESULTS

The majority of score results at both time points were in the lower range (mean 15-25), indicating limited financial difficulties. We observed no statistically significant differences by gender, marital status and age. Increasing financial difficulties during treatment were reported by male patients and those younger than 65, that is, patients who were younger than retirement age. The largest effect was seen in singles. However, differences were not statistically significant.

CONCLUSIONS

During the initial phase of the disease trajectory, no significant increase in financial difficulties was found. This is in line with the aims of the Norwegian public healthcare model. However, long-term longitudinal studies should be performed, especially with regard to the trends we observed in single, male and younger patients.
