Automated Cell Classification Pipeline
This study introduces a novel semi-automated pipeline that integrates Uniform Manifold Approximation and Projection (UMAP) with DBSCAN clustering and Support Vector Machine (SVM) to analyze flow cytometry data from bone marrow samples. The methodology is designed to overcome the limitations of traditional manual gating, providing a more efficient and accurate classification of B-cell pediatric leukemia.

Automated Patient Monitoring
High-Resolution B-Cell Maturation States
The UMAP and DBSCAN algorithms successfully identified four main cellular subpopulations in regenerated bone marrow (RBM) and distinguished B lymphocyte maturation states (Pro-B, Pre-B, Transition, Mature). This automated classification aligns with biological definitions and routine clinical analysis, demonstrating high agreement and resolution.
95%
Agreement with Manual Gating for MRD
UMAP and t-SNE techniques for flow cytometry data for early detection of MRD in leukemias and lymphomas resulted in over 95% agreement with manual gating.
The analysis revealed abnormal B lymphocyte percentages in leukemic bone marrow at diagnosis compared to RBM samples, consistent with the nature of B-ALL. Longitudinal monitoring highlighted the kinetic differences in B-cell compartment recovery between relapsing and non-relapsing patients, particularly at the +78 day mark.
Clinical Impact & Prediction
Our research demonstrates that automated analysis of bone marrow cell composition, especially B lymphocyte percentages and Mean Fluorescence Intensity (MFI) of specific markers like CD19 and CD20, can differentiate between relapsing (R) and non-relapsing (NR) B-ALL patients. These differences are particularly significant at the +78 day time point, offering valuable prognostic insights.
| Method | Accuracy |
|---|---|
| Random Forest (Without Oversampling) | 0.733 |
| Random Forest (With Oversampling, Train/Test) | 0.733 |
| Random Forest (With Oversampling, Cross-validation) | 0.760 |
The developed Random Forest classifier, incorporating oversampling and cross-validation, achieved an accuracy of 0.76 in distinguishing patient groups. This predictive capability, coupled with the system's ability to process samples in just two minutes, offers a significant advancement for routine clinical settings, aiding in early intervention and personalized therapy adjustments.
