Lung cancer poses multiple challenges to adopting an exercise (EX) program, and the ideal timing of an EX program to improve quality of life (QoL) is unknown. This study explored the EX counselling and programming preferences of lung cancer survivors and examined the association of EX before diagnosis, during treatment and after treatment on QoL.
Cross-sectional, retrospective survey design in a sample of lung cancer survivors. EX preferences were compared between patients who had received radical chest radiation or lung surgery versus those who had not. EX was measured by self-report using the Godin Leisure Time Exercise Questionnaire (GLTEQ). Separate linear regression models, controlling for significant covariates, examined the association of EX at each time point with scores on QoL measures and subscales.
Participants (N = 66, M age 66.4 ± 9.1) were between 4 months and 11.5 years after lung cancer diagnosis (M = 31.7 ± 22.9 months). Patients who had lung surgery were more likely to prefer to start an EX program during adjuvant treatment than those who did not have surgery (t(33) = 2.43, p = .025). Compared to prediagnosis EX (M = 36.7 ± 56.0 MET h/week), EX levels declined significantly during (M = 12.4 ± 25.0 MET h/week) and after (M = 12.3 ± 17.4 MET h/week) treatment (p < .05). After controlling for disease stage and income, regression models were not significant, but EX after treatment was a significant individual predictor of fatigue (β = .049, p = .006) and QoL measured by the Chronic Respiratory Disease Questionnaire (β = .163, p = .025).
Lung cancer patient preferences indicate that EX program timing should take into account whether the patient has undergone surgery. Lung cancer survivors' EX levels declined after diagnosis and engaging in EX after treatment may improve fatigue and QoL.
肺癌给采用运动(EX)计划带来了多重挑战,而改善生活质量(QoL)的运动计划的理想时机尚不清楚。本研究探讨了肺癌幸存者对运动咨询和计划的偏好,并研究了诊断前、治疗期间和治疗后运动与生活质量之间的关联。
对肺癌幸存者样本进行横断面回顾性调查设计。比较接受根治性胸部放疗或肺手术的患者与未接受此类治疗的患者的运动偏好。使用戈丁休闲时间运动问卷(GLTEQ)通过自我报告来测量运动情况。在控制显著协变量的情况下,采用单独的线性回归模型研究每个时间点的运动与生活质量测量指标及分量表得分之间的关联。
参与者(N = 66,平均年龄66.4±9.1岁)在肺癌诊断后4个月至11.5年之间(平均 = 31.7±22.9个月)。与未进行手术的患者相比,接受肺手术的患者更倾向于在辅助治疗期间开始运动计划(t(33) = 2.43,p = 0.025)。与诊断前的运动水平(平均 = 36.7±56.0代谢当量小时/周)相比,治疗期间(平均 = 12.4±25.0代谢当量小时/周)和治疗后(平均 = 12.3±17.4代谢当量小时/周)的运动水平显著下降(p < 0.05)。在控制疾病阶段和收入后,回归模型不显著,但治疗后的运动是疲劳(β = 0.049,p = 0.00)和慢性呼吸系统疾病问卷测量的生活质量(β = 0.163,p = 0.025)的显著个体预测因素。
肺癌患者的偏好表明,运动计划的时机应考虑患者是否接受过手术。肺癌幸存者诊断后的运动水平下降,治疗后进行运动可能改善疲劳和生活质量。
