Factors associated with return to work after breast cancer treatment

Relatively few studies have addressed problems regarding return to work after primary treatment for early-stage breast cancer. The purpose of this study was to investigate whether socio-economic and treatment-related factors were associated with problems of returning to work among pre-menopausal women included in a randomized trial of adjuvant endocrine therapy. The duration of all endocrine treatments in the trial was two years. At 24 months after randomization 35 of the 222 recurrence-free patients (16%) had not returned to work. The use of adjuvant endocrine therapy was associated with a twofold increase in the odds ratio of not having returned to work, although the confidence interval of this ratio was wide and included unity. Tumour stage was negatively associated with work status, possibly because of its association with adjuvant chemotherapy and radiotherapy to the regional nodes. Age and investigated social factors (educational level, matrimonial status and presence of under-age children) were not significantly associated with return to work. Determining the significance of other social factors such as vocational motivation, level of income and vocational rehabilitation merits further research.
