Work productivity loss in breast cancer survivors and its effects on quality of life.

Background Return to work is an important process for many breast cancer survivors (BCSs) that acts as a positive step towards their reintegration into society. Objectives This study examined whether work productivity loss due to presenteeism could predict the quality of life (QOL) of employed BCSs. Methods This study used a cross-sectional design. Seventy-five BCSs and seventy-five participants in the Non-Cancer Comparison (NCC) group were surveyed. The main outcome measures were productivity loss (as measured by the Work Limitations questionnaire) and quality of life (as measure by the European Organization for Research and Treatment Quality of Life questionnaire C30). Other measures included psychological distress (as measured by the Hospital Anxiety and Depression Scale) and cognitive limitation at work (as measured by the Cognitive Symptom Checklist). Results The BCS group had a lower summary score, a lower global health related score and greater work limitation in all domains than the NCC group. The productivity loss due to presenteeism of the BCS group was 8%. The multiple regression model shows that work productivity loss and level of job stress were the significant predictors of quality of life in the BCS group. Conclusion These findings raise questions about the effects of level of job stress and work productivity loss on the QOL of BCSs. Longitudinal studies are needed to map these relationships.
