“…HRQoL is a multidimensional construct encompassing patientsâ perceptions of domains such as physical, emotional, social, and cognitive functions [ 35 ], and these perceptions are influenced not only by exercise capacity [ 20 ], but also by clinical factors such as the administration of adjuvant chemotherapy [ 36 , 37 ], specific symptoms such as fatigue and pain [ 38 , 39 , 40 ], the extent of surgical resection [ 12 , 13 , 40 , 41 ], and psychosocial determinants such as anxiety, depression, self-efficacy, and social support [ 14 ]. Furthermore, evidence on the effects of pre- and/or postoperative exercise training on HRQoL has been limited to reviews that only included preoperative assessments [ 28 , 30 ], have not provided information on important health dimensions such as global quality of life and cancer-specific symptoms such as fatigue [ 34 ], and included non-randomized control trials in the quantitative synthesis [ 27 ], which tend to result in larger effect estimates [ 42 ].…”
