Multiple flow cytometry scores/diagnostic systems for the classification of leukemic lymphoproliferative disorders (LPD) have been published but few have been compared between them.
We classified a cohort of leukemic LPD based on eleven published flow cytometry scores/diagnostic systems and compared their classification as chronic lymphocytic leukemia (CLL) or non-CLL LPD.
329 patients were included. Patients classified as CLL ranged from 46% to 73%, depending on the score/diagnostic system used. All eleven scores/diagnostic systems agreed in 184/324 (57%) of patients while in 58/324 (18%) at least two scores/diagnostic systems classified the patient differently (from the majority). Fleiss kappa was 0.74, but pairwise agreement was variable (Cohen's kappa: 0.48 to 0.87).
This study found a suboptimal agreement between published flow cytometry scores/diagnostic systems for the classification of LPD.
已有多个流式细胞术评分/诊断系统用于白血病性淋巴增殖性疾病(LPD)的分类,但它们之间很少进行比较。
我们根据十一种已发表的流式细胞术评分/诊断系统对白血病性 LPD 进行分类,并比较了它们作为慢性淋巴细胞白血病(CLL)或非 CLL LPD 的分类。
共纳入 329 例患者。根据评分/诊断系统的不同,CLL 患者的比例范围为 46%至 73%。11 种评分/诊断系统在 324 例患者中的 184 例(57%)中一致,而在 324 例患者中的 58 例(18%)中至少两种评分/诊断系统将患者分类为不同的疾病(与多数情况不一致)。Fleiss kappa 值为 0.74,但两两之间的一致性存在差异(Cohen's kappa:0.48 至 0.87)。
本研究发现,已发表的用于 LPD 分类的流式细胞术评分/诊断系统之间的一致性较差。
