Purpose: The trial PhysSURG-B examined prehabilitation before breast cancer surgery by randomizing patients to a non-supervised physical activity or a control group. Within the trial, the effects on both short and long-term Quality of Life (QoL) was examined, with a pre-specified subgroup analysis of patients receiving adjuvant chemotherapy. Methods: Female patients planned for surgery were randomly assigned to either an intervention of 30 min of self-administered physical aerobic activity daily 2 weeks before and 4 weeks after surgery, or control. QoL was assessed with questionnaires at baseline, 4 weeks and 12 months post-op using the instruments FACT-B, RAND-36 and EQ-VAS. Results: Out of 354 included participants at 12 months after surgery, 287 were available for QoL analysis. FACT-B scores at 4 weeks and 12 months showed no differences between intervention compared to control, Odds Ratio (OR) of 0.975 and 0.883, respectively. There was no difference in EQ-VAS seen comparing intervention to control at 4 weeks and 12 months, respectively, OR=1.163 and 0.817. RAND-36 domains “role limitations due to physical health” and “pain” showed a decrease at 4 weeks in both groups, returning towards baseline at 12 months follow-up. The subgroup of patients receiving adjuvant chemotherapy had significantly lower QoL measured using FACT-B at 12 months compared to patients not receiving chemotherapy (OR=0.475). Conclusion: An intervention of non-supervised physical activity before and after surgery for breast cancer had no effect on short or long-term QoL, neither in the subgroup of patients receiving adjuvant chemotherapy.
