Wondering why leukemia patients need genetic testing? Director Zheng Qinlong explains its vital role in precision hematology care. Genetic heterogeneity drives varied chemo responses; gene sequencing guides targeted therapy, MRD surveillance and risk stratification. Comprehensive molecular profiling avoids ineffective regimens, cuts costs and enables personalized long-term treatment plans.

Clinical evaluations are systematically carried out centered on five core laboratory divisions (naming varies across hospitals): Cell Morphology Laboratory, Pathological Diagnosis Laboratory, Flow Cytometry Laboratory, Cytogenetics Laboratory, and Molecular Diagnosis Laboratory. Corresponding tests include cell morphology and cytochemical staining, pathology and immunohistochemistry, flow cytometry, karyotype analysis, FISH, gene testing, etc.

Many patients wonder: How long can CAR-T therapy last? Its long-term efficacy depends not only on the initial anti-tumor effect but also on the persistence of CAR-T cells in the body. Factors like T-cell quality, production process, tumor immune escape, and standardized whole-process management all affect outcomes. To improve durability, doctors recommend early intervention, optimized cell preparation, personalized targets, and long-term monitoring.
