Does physical activity improve quality of life in cancer patients undergoing chemotherapy?

ABSTRACT

BACKGROUND: Improved cancer treatments have resulted in prolonged survival. Nevertheless, tumor symptoms and side effects still compromise physical activity and quality of life (QoL). PATIENTS AND METHODS: We conducted an anonymous survey among cancer patients undergoing chemotherapy using standardized questionnaires the 'Freiburger Fragebogen zur körperlichen Aktivität' (Freiburg Questionnaire on Physical Activity) and European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30. Two main questions were addressed were there differences (1) in physical activity and QoL between patients who do not believe that sport could improve their QoL and those who believe it could (group A vs. B); and (2) in QoL between patients with a total activity (TA) < 18 metabolic equivalent of task (MET) h/week and those with a TA of ≥ 18 MET h/week (group C vs. D)? RESULTS: 276 of 400 questionnaires were completed. Groups A and B were balanced in terms of baseline characteristics. Group A suffered significantly more from fatigue and pain; group B reported higher levels of global health status (GHS) and TA. Groups C and D differed in gender distribution, age, and educational background. Group D had significantly higher levels of GHS, group C suffered more from fatigue, pain, and appetite loss. CONCLUSION: Physical activity correlates with a better QoL of cancer patients undergoing chemotherapy.
