Reduces post-operative complications
In patients with lung cancer, significantly fewer post-operative complications were reported from 2 meta-analyses of studies looking at pre-operative exercise interventions (4-5). A matched pair analysis study in gastric cancer patients with a high BMI found a pre-operative exercise programme reduced post-operative complications such as bleeding, pneumonia and post-surgical abdominal complications (7). In one prospective study, the patient group with the highest level of self-assessed physical activity required significantly less time off work compared to the group with physical activity levels of only 1-2 times per week (6).
Quality of evidence
Moderate quality – studies are heterogenous with regards to the design of prehabilitation programmes, risk of bias and small sample sizes. Further, large RCTs are recommended.
Strength of recommendation
Weak – on the basis of existing evidence and expert clinical opinion, some cancer patients may be expected to have fewer post-operative complications with pre-surgical physical activity
Preoperative exercise is safe and its benefits in reducing postoperative complications are promising and warrant further investigation.
