Employment two years after breast cancer diagnosis: role of household characteristics, CANTO cohort

Abstract

Abstract Background Breast cancer is associated with a high 5-year survival rate and more than half women are still of working age at diagnosis. Many studies evaluated the clinical determinants of return to work (RTW) but few investigated RTW in relation to family factors. Our objective was to study the role of household characteristics in non-RTW two years after breast cancerdiagnosis. Methods We used data of a French prospective cohort of women diagnosed with stage I-III, primary breast cancer (CANTO, NCT01993498). Patients had to be under 57 and have a job at diagnosis. We performed logistic regressions to model non-RTW two years after diagnosis in relation to household characteristics at diagnosis (marital status, children, support from partner), adjusting for tumor characteristics, health status at baseline and one year after diagnosis, and household income at diagnosis. In a second step, we conducted analyses stratified for household income at diagnosis. Results In total, 1874 women were eligible. Being in a relationship did not impact non-RTW (OR = 1.43 [95% CI 0.95-2.16]). Among the 1566 women in a relationship, being married was associated with elevated odds of non-RTW(OR = 1.37 [0.96-1.94]). Having children(OR = 1.17 [0.81-1.69]) or receiving support from their partner (OR = 1.17 [0.77-1.78]) was not associated with non-RTW. However, the situation differed in low-income households(<2500€) among whom being married was associated with more elevated odds of non-RTW(OR = 1.94 [0.97-3.88]). No clear association was observed between having children (OR = 1.85 [0.85-4.03]) and non-RTW, but living with at least two children (OR = 2.76 [1.14-6.70]) and receiving support from their partner (OR = 2.28 [1.01-5.17]) was associated with increased odds of non-RTW. Conclusions The family environment is associated with non-RTW among the poorest women but not the others. Key messages Among the poorest women, the family environment is associated with non-RTW. Among all women, the family environment is not associated with non-RTW.
