Flow cytometry has been widely used for the diagnosis of various hematopoietic diseases. Although there have been advances in the number of biomarkers that can be analyzed simultaneously and technologies that enable fast performance, the diagnostic data are still interpreted by a manual gating strategy. The process is labor-intensive, time-consuming, and subject to human error.
We used 80 sets of flow cytometry data from 44 healthy donors, 21 patients with chronic lymphocytic leukemia (CLL), and 15 patients with follicular lymphoma (FL). Approximately 15% of data from each group were used to build the profiles. Our approach was able to successfully identify 36/37 healthy donor cases, 18/18 CLL cases, and 12/13 FL cases.
This proof-of-concept study demonstrated that an automated diagnosis of CLL and FL can be obtained by examining the cell capture rates of a test case using the computational method based on the multi-profile detection algorithm. The testing phase of our system is efficient and can facilitate diagnosis of B-lymphocyte neoplasms.
流式细胞术已广泛应用于各种造血系统疾病的诊断。尽管在可同时分析的生物标志物数量以及实现快速检测的技术方面取得了进展,但诊断数据仍通过手动设门策略进行解读。该过程劳动强度大、耗时且容易出现人为误差。
我们使用了来自44名健康供者、21例慢性淋巴细胞白血病(CLL)患者和15例滤泡性淋巴瘤(FL)患者的80套流式细胞术数据。每组约15%的数据用于构建图谱。我们的方法能够成功识别36/37例健康供者病例、18/18例CLL病例和12/13例FL病例。
这项概念验证研究表明,通过基于多图谱检测算法的计算方法检查测试病例的细胞捕获率,可以实现CLL和FL的自动化诊断。我们系统的测试阶段效率高,有助于B淋巴细胞肿瘤的诊断。
