Considering current reliance on cancer registry data, we sought to assess the potential for bias in myelodysplastic syndrome (MDS) registration using SEER-Medicare data 2001-2005. Using a validated claims-based algorithm, we identified and compared registered and non-registered MDS patients, and found that median cumulative survival was 18 and 28 months, 74% and 64% used erythropoiesis-stimulating agents (ESAs), and average 6-month health care cost was $24,249 and $21,750, respectively. While most non-registered MDS patients showed resource utilization and survival characteristics consistent with lower-risk MDS, a subset was registered as acute myeloid leukemia (7.6%) and accounted for early mortality.
考虑到目前对癌症登记数据的依赖,我们试图利用 SEER-Medicare 数据(2001-2005 年)评估骨髓增生异常综合征(MDS)登记中存在的偏倚的可能性。我们使用经过验证的基于索赔的算法,确定并比较了登记和未登记的 MDS 患者,发现中位累积生存率分别为 18 个月和 28 个月,74%和 64%使用红细胞生成刺激剂(ESA),平均 6 个月的医疗保健费用分别为 24249 美元和 21750 美元。虽然大多数未登记的 MDS 患者的资源利用和生存特征与低危 MDS 一致,但有一部分被登记为急性髓系白血病(7.6%),并导致早期死亡。
