Patient-Reported Outcomes of Regular Aerobic Exercise in Gastric Cancer.

The benefits of exercise for health-related quality of life (HRQOL) and depression in patients with gastrointestinal disease remain unclear, and studies on gastric cancer are scant. This study examines the association between the maintenance of regular aerobic exercise at a recommended level and depression and HRQOL in patients with gastric cancer during or after treatment. In this cross-sectional study, a face-to-face survey was used to collect data from 126 patients with primary gastric cancer during or after treatment in a tertiary acute-care hospital in Korea. Regular exercise was defined as regularly maintained aerobic exercise of at least moderate intensity consuming ≥4 metabolic equivalents for ≥150 min/wk for at least 6 months. Depression was measured using the 9-item version of the Patient Health Questionnaire, and HRQOL was assessed using the EORTC QLQ-C30. Patients who maintained aerobic exercise at a recommended level were less likely to have depression and more likely to have improved global QOL, as well as physical, role, and emotional functioning. Patients with depression were less likely to report improved global QOL and functioning. Thus, exercise can have a synergistic effect on improvement in HRQOL via indirect positive effects on depression and direct effects on HRQOL in patients with gastric cancer. Oncology nurses should encourage patients with gastric cancer who suffer from a depressive mood to set up and implement specific plans for practicing regular exercise, which can lead to an improvement in both depression and HRQOL.
