Lifestyle interventions to improve the quality of life of men with prostate cancer : A systematic review of randomized controlled trials
A partir d'une revue systématique de la littérature publiée jusqu'en octobre 2015 (17 essais), cette étude analyse les effets des interventions destinées à améliorer les comportements de santé (meilleure alimentation, pratique d'exercices physiques, réduction des comportements à risque, ...) sur la qualité de vie des patients atteints d'un cancer de la prostate
Improving quality of life is a key issue for patients with prostate cancer (PCa). Lifestyle interventions could positively impact the quality of life of patients. However, there is no clear-cut understanding of the role of diet, exercise and risky behaviour reduction in improving the quality of life of men with PCa. The aim of this review was to systematically summarize randomized controlled trials on lifestyle in PCa patients with quality of life as main outcome. 17 trials were included. Most of them referred to exercise interventions (71%) and involved men undergoing androgen deprivation therapy (47%). Exercise studies yielded the greater amount of positive results on quality of life outcomes (67%), followed by dietary interventions (50%) and combined lifestyle interventions (33%). In particular, supervised exercise programs with resistance training sessions were the ones producing greater convincing evidence for benefits on quality of life. Further studies with high methodological quality providing adequate information to develop evidence-based, personalized lifestyle interventions that can effectively ameliorate PCa-related quality of life are needed.
