Exercise prescription for symptoms and quality of life improvements in lung cancer patients: a systematic review
A partir d’une revue systématique de la littérature publiée entre 1998 et 2019 (10 études, 835 patients), cette étude analyse les effets des exercices physiques sur les symptômes et la qualité de vie chez des patients atteints d’un cancer du poumon
Purpose :The purpose of this study was to conduct a systematic review to assess the effect of exercise on symptoms and quality of life in lung cancer patients. Methods : We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Medline, Embase, Scopus, Web of Science, and SciELO were searched for studies published from January 1998 to January 2019. The review included all randomized controlled trials that evaluated the effect of exercise on symptoms and quality of life of lung cancer patients. Two reviewers independently assessed the quality of all the included studies using the Physiotherapy Evidence Database scale. Results : In total, ten studies (835 participants) met all inclusion criteria. Three studies investigated the effect of exercise after lung resection, whereas four studies investigated it as a pre-surgery intervention. Two studies investigated the effect of exercise in patients under systemic treatment only, and one study included patients on diverse treatment plans. Exercise protocols consisted of different combinations of strength, aerobic, and inspiratory muscle training. Two trials, including 101 participants, found significant difference in quality of life between groups, favoring the intervention group; and five trials, including 549 participants, found significant inter-group differences in isolated symptoms, also favoring the intervention group. Conclusions : Exercise can lead to improvements of symptoms and of quality of life in lung cancer survivors. Providing resistance training combined with high-intensity interval aerobic exercise after lung resection seems to be particularly effective. Further studies are warranted to investigate exercise for patients with poor performance status.
