Impact of chemotherapy, radiotherapy, and endocrine therapy on sick leave in women with early-stage breast cancer during a 5-year period : a population-based cohort study

• Purpose: To examine the influence of type of oncological treatment on sick leave in women of working age with early-stage breast cancer.Methods: We identified 8870 women aged 30-64 diagnosed with stage I-II breast cancer between 2005 and 2012 in the Breast Cancer Data Base Sweden. Associations between type of oncological treatment (radiotherapy, endocrine therapy, and chemotherapy) and sick leave were estimated by hazard ratios, probabilities, and length of sick leave using multi-state survival analysis.Results: During the first 5 years after diagnosis, women aged 50-54 years at diagnosis receiving chemotherapy spent on average 182 (95% CI 151-218) additional days on sick leave compared with women not receiving chemotherapy, but with otherwise similar characteristics. Correspondingly, women initiating endocrine therapy spent 30 (95% CI 18-44) additional days on sick leave and women receiving post-mastectomy radiotherapy 53 (95% CI 37-69) additional days. At year five, the rate of sick leave was increased in women who had received chemotherapy (HR 1.19, 95% CI 1.11-1.28) or endocrine therapy (HR 1.15, 95% CI 1.05-1.26). Chemotherapy and endocrine therapy were associated with increased rates of sick leave due to depression or anxiety.Conclusion: Our findings of increased long-term risks of sick leave after oncological treatment for breast cancer warrant attention from caregivers taking part in cancer rehabilitation. In light of the ongoing debate about overtreatment of early-stage breast cancer, our findings point to the importance of properly selecting patients for chemotherapy not only for the medical toxicity but also the possible impact on their livelihood.
