长期生存的最新监测是基于人群和临床癌症登记的一项重要任务。几年前，引入了一种新的生存分析方法（称为周期分析），以提供更最新的长期生存估计。然而，典型的周期分析可能不适用于事件案例记录延迟的情况。我们在此引入一种混合类型的分析，它结合了传统分析和时期分析的元素，在这种情况下这仍然是可行的。与其他设计方案相比，混合类型分析的性能经过实证评估，并针对美国被诊断患有癌症的儿童进行了说明。实证评估表明，如果随着时间的推移生存率有显着改善，即使在事件病例记录严重延迟的情况下，与传统设计方案相比，混合分析可能有助于得出更最新的长期生存率估计。 (C) 2004 Elsevier Ltd. 保留所有权利。
Up-to-date monitoring of long-term survival is an important task of population-based and clinical cancer registries. A few years ago, a new method of survival analysis, denoted period analysis, was introduced to provide more up-to-date estimates of long-term survival. However, a prototypical period analysis may not be applicable in situations with delayed recording of incident cases. We introduce herein a hybrid type of analysis that combines elements of both traditional and period analyses which may still be feasible in such settings. The performance of the hybrid type of analysis compared with other design options is empirically evaluated and illustrated for children diagnosed with cancer in the United States. The empirical evaluation indicates that hybrid analysis may be useful to derive more up-to-date estimates of long-term survival compared with traditional design options if there is a strong improvement of survival over time, even in situations with a substantial delay in recording of incident cases.
