Abstract: | ObjectiveThe aim of this systematic review was to evaluate whether exercise prehabilitation programs reduce postoperative complications, postoperative mortality, and length of hospital stay (LoS) in patients undergoing surgery for non-small cell lung cancer (NSCLC), thereby accounting for the quality of the physical exercise program.MethodsTwo reviewers independently selected randomized controlled trials (RCTs) and observational studies and assessed them for methodological quality and therapeutic quality of the exercise prehabilitation program (i-CONTENT tool). Eligible studies included patients with NSCLC performing exercise prehabilitation and reported the occurrence of 90-day postoperative complications, postoperative mortality, and LoS. Meta-analyses were performed and the certainty of the evidence was graded (Grading of Recommendations Assessment, Development and Evaluation (GRADE)) for each outcome.ResultsSixteen studies, comprising 2,096 patients, were included. Pooled analyses of RCTs and observational studies showed that prehabilitation reduces postoperative pulmonary complications (OR 0.45), postoperative severe complications (OR 0.51), and LoS (mean difference −2.46 days), but not postoperative mortality (OR 1.11). The certainty of evidence was very low to moderate for all outcomes. Risk of ineffectiveness of the prehabilitation program was high in half of the studies due to an inadequate reporting of the dosage of the exercise program, inadequate type and timing of the outcome assessment, and low adherence.ConclusionAlthough risk of ineffectiveness was high for half of the prehabilitation programs and certainty of evidence was very low to moderate, prehabilitation seems to result in a reduction of postoperative pulmonary and severe complications, as well as LoS in patients undergoing surgery for NSCLC. |
