AIM: This study assessed the responsiveness and convergent validity of two preference-based measures; the newly developed cancer-specific EORTC Quality of Life Utility Measure-Core 10 dimensions (QLU-C10D) relative to the generic three-level version of the EuroQol 5 dimensions (EQ-5D-3L) in evaluating short-term health related quality of life (HRQoL) outcomes after esophagectomy. METHODS: Participants were enrolled in a multicentre randomised controlled trial to determine the impact of preoperative and postoperative immunonutrition versus standard nutrition in patients with esophageal cancer. HRQoL was assessed seven days before and 42 days after esophagectomy. Standardized Response Mean and Effect Size were calculated to assess responsiveness. Ceiling effects for each dimension were calculated as the proportion of the best level responses for that dimension at follow-up/post-operatively. Convergent validity was assessed using Spearman's correlation and the level of agreement was explored using Bland-Altman plots. RESULTS: Data from 164 respondents (mean age: 63 years, 81% male) were analysed. HRQoL significantly reduced on both measures with large effect sizes (> 0.80), and a greater mean difference (0.29 compared to 0.16) on QLU-C10D. Both measures had ceiling effects (> 15%) on all dimensions at baseline. Following esophagectomy, ceiling effects were observed with self-care (86%), mobility (67%), anxiety/depression (55%) and pain/discomfort (19%) dimensions on EQ-5D-3L. For QLU-C10D ceiling effects were observed with emotional function (53%), physical function (16%), nausea (35%), sleep (31%), bowel problems (21%) and pain (20%). A strong correlation (r = 0.71) was observed between EQ-5D-3L anxiety and QLU-C10D emotional function dimensions. Good agreement (3.7% observations outside the limits of agreement) was observed between the utility scores. CONCLUSION: The QLU-C10D is comparable to the more widely applied generic EQ-5D-3L, however, QLU-C10D was more sensitive to short-term utility changes following esophagectomy. Cognisant of requirements by policy makers to apply generic utility measures in cost effectiveness studies, the disease-specific QLU-C10D should be used alongside the generic measures like EQ-5D-3L. TRIAL REGISTRATION: The trial was registered with the Australian New Zealand Clinical Trial Registry (ACTRN12611000178943) on the 15th of February 2011.
目的:本研究评估了两种偏好测量方法的反应度和收敛效度;新开发的癌症特异性 EORTC 生命质量效用测量核心 10 维度(QLU-C10D)与通用三级版欧洲五维健康量表(EQ-5D-3L)在评估食管癌术后短期健康相关生活质量(HRQoL)结果方面的差异。
方法:参与者被纳入一项多中心随机对照试验,以确定术前和术后免疫营养与标准营养对食管癌患者的影响。HRQoL 在食管癌术前 7 天和术后 42 天进行评估。使用标准化反应均值和效应量评估反应度。计算每个维度的天花板效应,即该维度在随访/术后的最佳水平反应比例。收敛效度采用斯皮尔曼相关系数评估,采用 Bland-Altman 图探索一致性水平。
结果:对 164 名应答者(平均年龄:63 岁,81%为男性)的数据进行了分析。两种测量方法的 HRQoL 均显著降低,且 QLU-C10D 的效应量较大(>0.80),平均差异较大(0.29 比 0.16)。在基线时,两种测量方法在所有维度上均存在大于 15%的天花板效应。食管癌术后,EQ-5D-3L 的自我护理(86%)、移动性(67%)、焦虑/抑郁(55%)和疼痛/不适(19%)维度出现天花板效应。QLU-C10D 的情绪功能(53%)、身体功能(16%)、恶心(35%)、睡眠(31%)、肠问题(21%)和疼痛(20%)维度也出现了天花板效应。EQ-5D-3L 的焦虑和 QLU-C10D 的情绪功能维度之间存在很强的相关性(r=0.71)。效用评分之间的一致性较好(3.7%的观察值超出一致性界限)。
结论:QLU-C10D 与更广泛应用的通用 EQ-5D-3L 相当,但 QLU-C10D 对食管癌术后短期效用变化更为敏感。考虑到决策者在成本效益研究中应用通用效用措施的要求,应将疾病特异性 QLU-C10D 与通用措施(如 EQ-5D-3L)一起使用。
试验注册:该试验于 2011 年 2 月 15 日在澳大利亚和新西兰临床试验注册中心(ACTRN12611000178943)注册。
