Sickness absence and disability pension following breast cancer – A population-based matched cohort study.

Purpose To compare sickness absence and disability pension in a population-based cohort of women with breast cancer ( n = 463) from 1 year pre-diagnosis until 3 years post-diagnosis with a matched control group ( n = 2310), and to investigate predictors of sickness absence during the 2nd and 3rd year post-diagnosis. Results Following breast cancer, the proportion of disease-free women with sickness absence decreased post-diagnosis (1st–3rd year; 78%-31%-19%), but did not reach the pre-diagnostic level (14%; P < 0.05). Post-diagnosis, patients were more likely than controls to be sickness absent (1st–3rd year; P < 0.001). No between-group differences were observed for disability pension post-diagnosis ( P > 0.05). Among patients, chemotherapy, baseline fatigue and pre-diagnosis sick days predicted sickness absence during the 2nd, 3rd, and 2nd and 3rd year post-diagnosis, respectively ( P < 0.05). Conclusions Breast cancer is associated with increased sickness absence 3 years post-diagnosis. In a clinical setting, prevention and treatment of side effects are important in reducing long-term consequences. [ABSTRACT FROM AUTHOR]
