Abstract: To assess the effects of a group class physical exercise program on health-related quality of life (HRQOL), physical fitness and activity, and safety in early breast cancer women after treatment, a double phase trial [16-week control phase (CP) followed by a 16-week intervention phase (IP)] was designed. Outcomes were evaluated at baseline (T1), 8 (T2) and 16 (T3) weeks (CP), and 24 (T4) and 32 (T5) weeks (IP). The primary endpoint was global health status. Out of 82 enrolled patients, 37 completed the IP. Global health status decreased (−10,1; 95% CI −19.8 to −0.4; p = 0.040) during the CP and stabilized during the IP. Physical and sexual functioning increased during the IP (p = 0.008; p = 0.017), while cardiorespiratory fitness increased in the CP (p = 0.004). Upper limb strength and lower limb functionality increased during both phases [CP: p < 0.0001, p = 0.001 (surgical and nonsurgical arm), p = 0.028; IP: p < 0.0001, p = 0.002, p = 0.009]. Body mass index decreased in the IP (p = 0.026). Waist circumference increased in the CP (p = 0.001) and decreased in the IP (p = 0.010); sedentary behaviours and moderate and vigorous physical activity did not change. Adherence to 70% of the sessions was reported in 54% of patients. No serious adverse events related to the intervention were reported. In conclusion, the physical exercise program was able to prevent the decline in global health status and to improve other domains of HRQOL and physical fitness. As physical exercise is not the standard of care in many countries, the implementation of group class programs might be an option.
