Association of physical activity with health-related quality of life in rectal cancer survivors

Abstract Background Health-related quality of life (HRQoL) in rectal cancer survivors after completion of surgical treatment may be influenced by various factors including physical activity. The purpose of this study was to examine the association between regular exercise and physical and mental health in rectal cancer survivors. Methods People who underwent surgical resection of rectal cancer with temporary ileostomy from 2018 to 2021 were invited to participate. Participants were drawn from the Clinic for Digestive Surgery and the Clinic for Emergency Surgery of the University Clinical Center of Serbia, as well as the nationwide laparoscopic program - LapSerb consortium. Data were collected through interviews in late 2022 and early 2023. The HRQoL was evaluated using the physical composite score (PCS) and mental composite score (MCS) of the Short Form-36 (SF-36) questionnaire. Socio-demographic, clinical and behavioral characteristics including the frequency of exercise were analyzed in multiple linear regression models. Results A total of 134 rectal cancer survivors were tested. Few participants (18.7%) exercised regularly, while most of the study population occasionally (41.8%) or never engaged (39.5%) in physical activity. Rectal cancer survivors who exercised regularly had significantly higher scores of physical (75.5 vs. 62.8, p = 0.019) and mental quality of life (78.9 vs. 63.8, p = 0.008). Regular exercise remained associated with better physical and mental health after the adjustment for demographic, clinical and behavioral characteristics. Conclusions Consistent physical exercise seems to be significant contributor of better physical and mental quality of life in rectal cancer survivors after completion of surgical treatment. Key messages • Physical exercise may help rectal cancer survivors improve their physical and mental health. • Promotion of physcial activity in rectal cancer survivors could optimize recovery after surgery.
