患者的身体机能在癌症患者的治疗处方中起着主导作用。对身体功能的客观评估可能比经常使用的主观指标(如东方合作肿瘤学组织/世界卫生组织(ECOG/WHO)绩效评分)更能预测治疗耐受性和存活率。使用智能手机测量身体活动和健康状况可能提供一个极好的机会，在低成本和短时间的情况下客观地评估患者的身体功能。我们调查了智能手机测量癌症患者步数和体能的可行性、有效性和可靠性。总共有72名患者参与其中。他们佩戴了14天的智能手机，以测量平均每天的步数，并在前7天配上了加速度计。患者通过智能手机应用程序在户外进行了两次6分钟步行测试(6MWT)，一次是在医院的测试环境中。可行性是通过完成研究的患者比例以及智能手机对步数和身体健康的评估来评估的。通过组内相关系数(ICC)评估加速度计与智能手机使用第一周步数之间的相关性，以及医院内6MWT与体能应用之间的相关性。在智能手机评估的第一周和第二周的步数水平之间，以及在家庭环境中的第一次和第二次6分钟步行测试之间，使用ICC评估了测试-重测的可靠性。智能手机测量的准确率在步数方面约为90%，在身体健康评估方面约为%。步数的效度(ICC = 0.97，p<； 0.001)和健身的一般(ICC = 0.47，p<； 0.001)的效度都很好。我们发现步数(ICC = 0.91，P<； 0.001)和身体健康(ICC = 0.88，P<； 0.001)具有极好的重测可靠性。本研究表明，客观智能手机测量步数在临床实践中是可行、有效和可靠的。这些发现表明，在癌症临床实践中使用智能手机客观评估体力活动是有前景的，可以用于选择患者进行治疗和参与研究，在治疗过程中监控患者，并指导治疗决策。
A patient’s physical function plays a leading role in the treatment prescription for patients with cancer. Objective assessments of physical function may be more predictive for treatment tolerability and survival than frequently used subjective measures, such as the Eastern Cooperative Oncology Group/World Health Organization (ECOG/WHO) performance score. The use of smartphones to measure physical activity and fitness may provide an excellent opportunity to objectively estimate a patient’s physical function against low costs and little time. We investigated feasibility, validity and reliability of smartphone measurements of step count and physical fitness in patients with cancer. In total, 72 patients participated. They wore a smartphone for 14 days to measure the mean number of steps per day, concomitant with an accelerometer during the first 7 days. Patients performed a six-minute walk test (6MWT) twice outdoors via a smartphone application and once in a test environment in the hospital. Feasibility was evaluated by the proportion of patients who completed the study as well as smartphone assessments of step count and physical fitness. Validity was assessed with the intraclass correlation coefficient (ICC) between the accelerometer and the first week of the smartphone for step count, and between the 6MWT in the hospital and via the application for physical fitness. Test-retest reliability was assessed with the ICC between step count levels of the first and second week of smartphone assessments, and between the first and second six-minute walk test in the home environment. The completeness of smartphone measurements was approximately 90% for step count and 64% for physical fitness assessments. Validity was excellent for step count (ICC = 0.97, p < 0.001) and fair for fitness (ICC = 0.47, p < 0.001). We found excellent test-retest reliability for step count (ICC = 0.91, p < 0.001) and physical fitness (ICC = 0.88, p < 0.001). This study showed that objective smartphone measurements of step count in clinical practice are feasible, valid and reliable. These findings indicate that the use of smartphones to objectively assess physical activity in clinical cancer practice is promising and may be used to select patients for treatment and study participation, to monitor patients during treatment and to guide treatment decisions.
