      abstract     = {Benefits of exercise interventions for cancer patients are
                      well established. This systematic review aimed to
                      investigate the sustainability of exercise interventions
                      with respect to physical activity behaviour of breast cancer
                      patients in the longer term.The databases Pubmed, Cochrane,
                      Embase, and Web of Science were systematically searched for
                      randomized controlled trials (RCTs) investigating aerobic
                      exercise, resistance exercise, or combined exercise
                      interventions in breast cancer patients and assessing
                      physical activity at least 2 months after the intervention.
                      Random-effect models were used to calculate standardized
                      mean differences (SMD).A total of 27 RCTs with 4120
                      participants were included in the review, of which 11 RCTs
                      with 1545 participants had appropriate data for the
                      meta-analyses. Physical activity was mainly self-reported,
                      and most exercise interventions were supervised. Exercise
                      interventions tended to show a moderate significant effect
                      up to 6 months for moderate to vigorous physical activity
                      (SMD $[95\%$ CI] = 0.39 [0.07, 0.70]) and small,
                      non-significant effects on total physical activity at 6
                      months (SMD $[95\%$ CI] = 0.14 [- 0.00, 0.28]) and up to 60
                      months after the intervention (SMD = 0.29 [-0.31, 0.90]).
                      Differences between intervention characteristics, such as
                      supervised versus unsupervised, were inconclusive due to the
                      small number of RCTs.The physical activity behaviour in
                      breast cancer patients remained improved for several months
                      beyond the end of exercise interventions, but effects were
                      small to moderate and diminished over time. Future studies
                      should clarify how to maintain a healthy level of physical
                      activity after completion of an exercise intervention.},
