Predictors of return to work after autologous stem cell transplantation in patients with multiple myeloma.

Return to work (RTW) is a marker of functional recovery in cancer patients, with quality of life, financial and social implications. We investigated frequency and factors associated with RTW in a cohort of patients younger than 66 years, with newly diagnosed multiple myeloma (MM), uniformly treated with a bortezomib-based induction followed by autologous stem cell transplantation (ASCT). Socio-economic and working status data were collected by a self-administered questionnaire. One hundred and eighty-six patients entered the study. Of whom, 145 (78%) where employed at diagnosis, which was more frequent in younger (median 55 vs. 60 years, p < 0.001), men (59.3% vs. 34.2%, p = 0.004), and with college studies (44.8% vs. 24.4%, p = 0.008). Forty-three (30%) of the 145 patients who had a job at diagnosis, RTW after ASCT in a median of 5 (range 1-27) months. Factors independently associated with RTW were having three or more children (HR 2.87, 95% CI 1.33-6.18), college studies (HR 2.78, 95% CI 1.21-6.41), and a family income >40 × 103€/year (HR 2.31, 95% CI 1.12-4.78). In conclusion, the frequency of RTW herein reported in MM patients seems lower than reported in other malignancies. The risk factors observed may guide the design RTW programs.
